文章大意:本文是一篇说明文。文章主要介绍了芝加哥大学的苏珊·戈尔丁-梅多的新的研究发现,她认为情绪以多种方式表现出来:面部表情、姿势、语调等等。但是,当人们在说话时使用手势时,他们的行为是不同的。

1 . “Tie an Italian’s hands behind his back,” runs an old joke, “and he’ll be speechless.” This rests on a national stereotype: Italians are talkative and emotional, and all that arm-waggling supposedly goes to prove it.

Susan Goldin-Meadow of the University of Chicago has a rather different view. Emotions come out in lots of ways: facial expressions, posture, tone of voice and so on. But people are doing something different when they use gestures with speech, which she sums up in the title of her new book, “Thinking with Your Hands”. It is a masterly tour through a lifetime’s research.

Virtually everyone gestures, not just Italians. Experimental subjects, told after a research session that they were being watched for gestures, apologize for not having made any — but were doing so the entire time. People born blind gesture when they speak, including to each other. A woman born without arms but with “phantom limb syndrome (幻肢综合征)” describes how she uses her phantom arms when she talks — but not when she walks. All this suggests that cognition is, to some extent, “embodied”; thinking is not all done in your head.

In fact, gestures that accompany speech are a second channel of information. Subjects watch a film in which a cat runs but are told to lie and say it jumped. They do so in words — while their hands make a running motion. People who say they believe in sexual equality but gesture with their hands lower when talking about women are not indicating women’s height; they can be shown to have biases of which they may be unaware.

In “The Crown”, a historical drama series, Lady Diana is warned that her hands may betray her real emotions, which could be dangerous; they are tied together so she can learn to speak without gesticulating. No one who reads Susan’s book could ever again think that gesturing shows only a lack of control. It is about thinking and communication, and is a sophisticated aid to both.

1. Why does the author mention the old joke in Paragraph 1?
A.To present an argument.B.To describe a scene.
C.To lead in the topic.D.To clarify a doubt.
2. Which statement will Susan Goldin-Meadow probably agree with?
A.The disabled seldom use gestures.B.Gestures literally embody cognition.
C.Thinking only occurs inside the brain.D.Gestures are improper in communication.
3. What does the author try to prove in the last two paragraphs?
A.Gestures may express what the speaker really thinks.
B.People are unaware of the meanings of their gestures.
C.Gesturing during speech shows only a lack of control.
D.Speakers can lie more easily with the help of gestures.
4. Which of the following is the best title for the text?
A.Speech: A Direct Channel of InformationB.Gestures: A Vital Form of Communication
C.Italian’s Body Language: A National StereotypeD.Thinking with Your Hands: A Lifetime’s Research

文章大意:这是一篇说明文。文章主要介绍了西瓜的起源。

2 . The green and red watermelon is a sweet, refreshing summer snack. But it wasn’t always so sugary or brightly colored. So what did watermelons originally taste and look like, and from where did they come?

The fruit isn’t from the Fertile Crescent of ancient Mesopotamia, as so many other domesticated (家养的) crops are, research shows. Susanne Renner, a scientist, and her colleagues carried out comprehensive genetic sequencing (基因测序) of the domesticated watermelons — the kind you might find on supermarket shelves — along with six wild watermelon species.

“We found the modern genomes (基因组) of the domesticated watermelon are more closely related to the Sudanese wild type than any other that we analyzed,” she said. The Sudanese wild watermelon has some obvious differences from the domesticated version. “The flesh is white and not very sweet, and it’s mainly used as animal feed,” Renner said. Nevertheless, the genetic similarity between the two species led the researchers to conclude that the Sudanese fruit is probably a precursor (前身) to the red and sweet domesticated watermelon.

It’s likely that ancient farmers grew non-bitter varieties of the wild watermelon and thus increased its sweetness over many generations through the domestication process. The red color is probably also thanks to artificial selection, in which farmers likely favored and selectively bred red fruit.

We already knew that the ancient Egyptian king Tutankhamun was buried with watermelon seeds 3,300 years ago, yet that isn’t sufficient proof of a domesticated, sweet watermelon. But then, Renner found an image of a watermelon-like fruit on an ancient Egyptian tomb painting, thought to be more than 4,300 years old. In a separate tomb, another image showed the watermelon cut up in a dish alongside other sweet fruits. This realization, coupled with Renner’s genetic findings, suggests that the watermelon was most likely domesticated around that time either in Egypt or within trading distance of the ancient empire.

“Historically speaking, that’s a very significant finding,” said Hanno Schaefer, a professor of plant biodiversity. “It’s becoming clearer that we’ve greatly neglected the North African region. We’ve focused too much on the Fertile Crescent and we need to invest more resources into studying the agriculture of North Africa.”

1. What can we learn about the Sudanese wild watermelon?
A.It is brightly colored and sugary.
B.It is consumed mainly by animals.
C.It has no connection with the domesticated type.
D.It has more differences than similarities to the domesticated type.
2. What can be inferred from the text?
A.More resources will be devoted to agriculture research in South Africa.
B.The domesticated watermelon has a history of at least four thousand years.
C.The domesticated watermelon probably developed from the Sudanese type.
D.Few domesticated crops are from the Fertile Crescent of ancient Mesopotamia.
3. What is the fourth paragraph mainly about?
A.The history of the Sudanese wild watermelon.
B.Where wild watermelons actually come from.
C.The characteristics of domesticated watermelons.
D.How domesticated watermelons came into being.
4. What is Hanno Schaefer’s attitude towards Renner’s findings?
A.Favorable.B.Doubtful.C.Critical.D.Tolerant.

文章大意:本文为一篇说明文,科学家担心太空碎片的风险日益增加,一些经济学家提出“向卫星运营商收取轨道使用费”的建议,文章引用几个人的观点说明了该建议是否可行。

3 . Orbital structures are becoming increasingly important for worldwide communications and a new generation of technologies. But scientists are warning that the danger of space debris (碎片)is rapidly increasing . Space debris can include pieces of old rockets, non-operational satellites, lost tools and other parts. These pieces of wreckage present a risk to spaceships, satellites and space stations.

In an effort to reduce the amount of debris orbiting the Earth, some experts suggest creating “orbital-use fees.” A group of economists at the University of Colorado at Boulder proposed a yearly fee, or tax, on satellite operators for their use of an orbital path. The group’s study on the subject appeared recently in the publication Proceedings of the National Academy of Sciences.

Matthew Burgess helped write the study. He said in a statement: “Space is a common resource, but companies aren’t accounting for the cost their satellites impose on other operators when they decide whether or not to launch. So we need a policy that lets satellite operators directly factor in the costs their launches impose on other operators.”

Akhil Rao was the lead writer of the study. He said most proposed answers to the problem have been based on using technology to clear away the debris. Some suggestions, for example, call for nets or other devices that capture the space wreckage. But, Burgess said that removing debris only means that operators will launch more satellites. He said an international treaty calling for a yearly fee or tax would push companies to be more mindful about launching more objects into space.

Christopher Newman is a professor of space law at North Umbria University in Britain. He told the Thomson Reuters Foundation that carrying out a space tax could be tricky. Newman noted that such a cost could be seen as a restriction on the free use of space. That freedom is guaranteed in the Outer Space Treaty of 1967. The United Nations document has been signed by more than 100 nations. Newman added that the effort to place a fee on the use of space could easily be slowed by the many details involved.

1. What worries the scientists?
A.the high cost of cleaning spaceB.the increasing risk of space debris
C.the safety of communication systemD.the practical effects of new technologies
2. What was the economists’ suggestions?
A.Strengthening control over space stations.
B.Allowing companies to use space for free.
C.Charging satellites operators’ orbit-use fees.
D.Using advanced devices to catch space debris.
3. What is Burgess’s attitude towards clearing away the debris?
A.Supportive.B.Neutral.C.IndifferentD.Negative.
4. What did Newman think of the economists’ idea?
A.It would lead to an argument.B.It was well worth considering.
C.It was hard to put into practice.D.It would eventually be rejected.

文章大意:本文是一篇新闻报道。主要报道的是最近考古学家在三星堆遗址的一些惊人的发现。

4 . A RCHAEOLOGISTS have recently made some stunning discoveries at the famed Sanxingdui Ruins site in Sichuan province.

A treasure trove of bronze, gold and jade wares have been uncovered from the site’s six pits. At least 10 of the bronze wares in the trove have never been seen in the history of human civilization.

Researchers described a bronze box with a piece of green jade ware inside of it as the highlight of the 10 relics. The top and bottom of the vessel are covered with turtle shell-shaped lids, each of which resembles a net. And the sides of the box are decorated with dragon head-shaped handles and a few bronze streamers (饰带).

“It would not be an exaggeration to say that the vessel is one of a kind, given its distinctive shape, fine craftsmanship and clever design,” said Professor Li Haichao at Sichuan University. “Although we do not know what this vessel was used for, we can assume that ancient people treasured it.”

Another new find from the past was a bronze altar nearly 0.9 meters tall, upon which researchers believe the people of the Shu civilization made offerings to heaven, earth and their ancestors.

......

1. Which of the following vessels is the most impressive?
A.A bronze box.B.A jade ware.
C.A bronze streamer.D.A green zun.
2. What may the bronze altar be used for?
A.Offering heaven and earth.B.Honoring their ancestors.

5 . With the availability of easy-to-use at-home kits, DNA testing for dogs has become increasingly popular among dog owners in recent years. It can provide invaluable insights into a dog’s breed, health risks, and even behaviors.

DNA testing typically works by analyzing the genetic material found in a sample of cells taken from the inside of your dog’s cheek. This sample is then compared to a database of known breeds and genetic markers associated with certain traits or health conditions.

The first step in obtaining a DNA test kit is selecting which type you want. Most companies offer several different types of tests that vary in cost and complexity. For instance, some tests just analyze your dog’s breed composition, while others can assess additional genetic markers associated with certain diseases or behaviors.

Then it’s time to collect your dog’s sample using the provided swab (拭子) kit or saliva-collection tube included with most kits. The swab should be gently rubbed inside your pet’s cheek according to the kit’s directions before being placed into the collection container provided by the company. After collecting the sample, it should be mailed back to the laboratory for processing according to instructions given by the company providing the service. Once received by the lab, it typically takes 1-2 weeks for results to be processed and sent back via email or mail. Results will vary depending on which type of test was purchased, but they generally include detailed information about your pet’s breed composition as well as any potential health risks or behavioral traits associated with their genetics that could affect their overall well-being and quality of life.

If you’re looking for an easy way to learn more about your pup’s background without spending too much money, then DNA testing might just be right up your alley.


What is the correct order of having an DNA test?
①get the sample processed          ②rub the swab gently                             ③receive the result  
④select the type of test                  ⑤place the swab into the container         ⑥mail the sample back to the lab
A.④-②-⑤-⑥-①-③B.④ ⑤-①-②-⑥-③
C.②-⑤-④-①-⑥-③D.②-④-⑤-⑥-①-③

文章大意:本文是一篇说明文。文章主要介绍了一项新的研究发现,该研究发现最有害的人际关系不是纯粹负面的关系,而是混合了正面和负面情绪的关系,这种关系被称为“亦敌亦友”的关系,即有时帮助你,有时伤害你的关系。

6 . We often think about relationships on a scale from positive to negative. We are drawn to loving family members, caring classmates and supportive mentors. We do our best to avoid the cruel uncle, the playground bully and the jerk boss.

But the most harmful relationships aren’t the purely negative ones. They’re the ones that are a mix of positive and negative. We often call them frenemies, supposed friends who sometimes help you and sometimes hurt you. But it’s not just friends. It’s the in-laws who volunteer to watch your kids but devalue your parenting. The manager who praises your work but denies you a promotion.

Groundbreaking research led by the psychologists Bert Uchino and Julianne Holt-Lunstad shows that ambivalent (矛盾情绪的) relationships can be damaging to your health — even more than purely negative relationships.

Even a single ambivalent interaction can cause harm. In one experiment, people talked about controversial (具有争议性的) topics in front of a friend who offered feedback. The researchers had randomly assigned the friend to give ambivalent or negative comments. Receiving mixed feedback caused higher blood pressure than pure criticism. “I would have gone about the topic differently, but you’re doing fine” proved to be more distressing than “I totally disagree with everything you’ve said.”

The evidence that ambivalent relationships can be bad for us is obvious, but the reasons can be harder to read — just like the relationships themselves.

One reason is that ambivalent relationships are unpredictable. With a clear enemy, you put up a shield when you cross paths. With a frenemy, you never know whether Dr. Jekyll or Mr. Hyde is going to show up. Feeling unsure can break the body’s calming system and activate a fight-or-flight response. It’s unsettling to hope for a hug while also preparing for a likely quarrel.

Another factor is that unpleasant interactions are more painful in an ambivalent relationship. It’s more distressing to be let down by people you like sometimes than by people you dislike all the time. When someone stabs you in the back, it stings more if he’s been friendly to your face.

1. Which of the following can be considered as a frenemy?
A.Your neighbor’s kid who advises you to study hard but kill his own time.
B.Your classmate who admires your hard work at first, but doubts your intelligence later.
C.Your mother’s friend who encourages you to spend more time on homework but less on smart phones.
D.Your father’s colleague who proposes you to do a reasonable amount of homework while ensuring enough sleep.
2. What does the underlined word “distressing” in Paragraph 4 probably mean?
A.Upsetting.B.Satisfying.C.Inspiring.D.Confusing.
3. Which of the following statements can be inferred from the passage?
A.The negative impact of ambivalent interactions is strong.
B.Ambivalent relationships have a long-lasting effect on your well-being.
C.The common cause of high blood pressure is ambivalent relationship.
D.Interactions in ambivalent relationships are more painful than those in negative ones.
4. What is the passage mainly about?
A.Negative relationships are bad for health.B.Ambivalent relationships are unpredictable.
C.Ambivalent Relationships are the most harmful.D.Positive relationships are better than negative ones.

文章大意:本文是一篇说明文,主要解释了在牛体内放磁铁这种做法的原因。

7 . While we aim to avoid any appearance of baseless theories, it is noteworthy to observe the long-standing practice of putting magnets (磁铁) in cows, a phenomenon that has been carefully unfolding for years. Why are farmers putting magnets in cows?

Known as cow magnets, the devices are placed inside cattle to deal with “hardware disease”. Hardware Disease occurs after an animal eats a metallic object that then makes a hole in the wall of the reticulum, the second stomach room in ruminant animals (反刍动物). This issue arises from the natural eating behaviors of these ruminants, similar to a person at an unlimited food event — quickly and eagerly large bites without sufficient chewing. This fast-paced feeding approach makes them tend to unintentionally consume metal pieces in their food, including broken farm machinery parts, nails and wires used in fencing, for instance.

Metal objects entering the reticulum may result in infections, increased body temperatures, digestive problems, and unease for the animals. To address hardware disease, the main strategy is to prevent metal from entering the cattle’s diet. Farmers have also adopted the method of placing cow magnets into the stomach using either a stomach tube or a balling gun. The cow magnet attracts such objects and prevents them from becoming fixed in the animal’s tissue. These magnets, once positioned, remain within the animals throughout their lifespan, only being removed after death when the cows pass away or are processed for meat.

Moseley, a Veterinary Medicine professor, states in a hardware disease resource, “The magnet gathers foreign metallic objects, reducing the risk of making a hole in the reticulum.” Research shows a mild magnetic field affects a cow’s small blood pathways, improving circulation and aiding recovery without significant impact on the cow or milk quality.

1. Why are magnets fed to cows?
A.To change feeding habits.B.To prevent hardware disease.
C.To improve the milk quality.D.To enhance digestive system.
2. What is the main cause of hardware disease in ruminant animals?
A.Eating without chewing.B.Taking magnets by mistake.
C.Sufficient chewing hard food.D.Swallowing metals accidentally.
3. What is the author’s purpose in writing the passage?
A.To describe the historical practice of putting magnets in cows.
B.To deny the adoption of cow magnets to enhance cattle health.
C.To discuss the influence of a mild magnetic field on milk quality.
D.To explain the reason for using magnets to prevent hardware disease.
4. What might be a logical continuation of the passage?
A.Exploring more potential benefits of cow magnets.
B.Investigating the broader applications of magnets.
C.Discussing the alternative methods of caring for cows.
D.Evaluating the long-term effects of magnets on animals.

文章大意:本文是说明文。在中国发现的化石表明约2.5亿年前,海洋动物湖北鳄已经进化出了和须鲸类似的滤食系统。

8 . Baleen whales (须鲸), such as the blue whale, are huge sea animals. “Baleen” describes a filter-feeding (滤食的) system in their mouths through which they can eat huge numbers of very small ocean animals. But it appears now that whales are not the first sea animals to filter-feed.

Scientists recently reported their findings about the ancient remains of a sea animal called Hupehsuchus nanchangensis that lived 248 million years ago, during the Triassic Period. They say its fossil (化石), which was unearthed in China’s Hubei Province, presents evidence of a filter-feeding system similar to that of baleen whales.

Unlike blue whales, Hupehsuchus was not large. The animal measured about one meter long. Its mouth was narrow and toothless. Its lower jaw was loosely connected to the rest of the head bone. This permitted the animal to open its mouth wide to take in a large amount of water and the animals it carried. The structure traps little sea animals but lets the seawater flow out.

From two new fossils with well-kept head bones the scientists found evidence along the jaws suggesting the presence of soft tissue s that could have served as baleen. “We were amazed to discover the adaptation in such an early sea animal,” said Fang Zichen of the Wuhan Center of China Geological Survey.

Paleontologist Mike Benton said, “Altogether, this points to a soft pocket of skin around the mouth and throat, as in modern baleen whales, and some kind of filtering device hanging from the jaws, like baleen.” But, he added, the baleen and skin were not fossilized.

According to scientists, Hupehsuchus’ feeding style would match that used by baleen whales. This feeding structure is an example of a phenomenon in which distinct organisms independently evolve similar features—like the wings of birds and bats—to adapt to similar environments.

1. Why are baleen whales mentioned in the first paragraph?
A.To present another sea animal.B.To awaken curiosity about huge whales.
C.To draw attention to their current state.D.To introduce their unique feeding pattern.
2. Which aspect of Hupehsuchus is mainly discussed in paragraph 3?
A.How it filter-fed.B.Its lower jaw's function.
C.Why it grew toothless.D.Its physical characteristics.
3. What surprised the scientists about Hupehsuchus?
A.Baleen surrounded the jaws.B.It could feed and live in the sea.
C.It developed a filter-feeding system.D.Two undamaged head bones were found.
4. Which can be a suitable title for the text?
A.Hupehsuchus Proving to Be a Filter-feeder
B.Hupehsuchus Appearing Earlier than Whales
C.Scientists Unlocking the Secrets of Hupehsuchus
D.New Evidence Telling Hupehsuchus'Evolution

文章大意:本文是说明文,几十年来,研究认为抑郁或焦虑导致了睡眠不足,但是现在的研究表明,很可能是失眠导致了抑郁或焦虑的产生。

9 . When I was a graduate student, my co-workers and I were wondering how losing one night of sleep affects a person's ability to manage their emotions.

Once a week, typically on Friday evening, we would stay up all night to monitor our participants and ensure they followed the experimental plan. At about noon the next day, we would all go out of the lab, worn oat and eager to get home and rest.

Two months into the experiment, I was in my car at a traffic light when a silly love song started playing on the radio. Suddenly, I cried uncontrollably. I remember feeling surprised at my reaction. It then hit me that I was not just studying sleep deprivation (睡眠剥夺) —I had become part of the study. Weeks of missed sleep had caused harm, and I was no longer in control of my emotions.                                 

That research project proved a strong connection between good sleep and emotional health. In healthy individuals, good-quality sleep is linked with a more positive mood ——and it takes just one night of sleep deprivation to cause anxiety and depression the following morning. Moreover, people who suffer from long-term sleep deprivation tend to experience daily events more negatively.

For decades researchers and medical professionals have considered sleep loss a by-product or symptom (症状) of depression or anxiety. In other words, first comes the anxiety, and then sleep loss. Today we know that this order can be reversed. Much evidence shows that people who suffer from insomnia (失眠症)are at least twice as likely to develop depression or anxiety later in life, compared with individuals who sleep well.

Stepping back, we can find that mental and emotional health rely on a delicate balance. A single sleepless night can therefore do damage. The science of sleep and mental health suggests that failing to address the problems that prevent people from getting enough rest will leave people easily hurt in mind.

1. What is the author’s research mainly about?
A.Factors that affect emotions.B.The damage of sleep deprivation.
C.Ways to improve mental health.D.The link between sleep and emotions.
2. How was the research conducted?
A.By referring to previous research.B.By making researchers the subjects.
C.By doing experiments on participants.D.By including music in the process.
3. Why did the author burst into tears?
A.The love song was so touching.B.The research was too stressful.
C.She missed her family too much.D.She was severely lacking in sleep.
4. Which word can replace the underlined word “reversed” in paragraph 5?
A.Disclosed.B.Switched.C.Identified.D.Arranged.

文章大意:这是一篇说明文。主要介绍了一项新的研究表明,一种名为赤藓糖醇的糖替代品与血液凝固、中风、心脏病发作和死亡有关。

10 . A sugar replacement called erythritol (赤藓糖醇) has been linked to blood clotting (血液凝固), stroke, heart attack and death, according to a new study.

“The degree of risk was not modest,” said lead study author Dr. Stanley Hazen. People with existing risk factors for heart disease will be twice as likely to experience the risk if they have the highest levels of erythritol in their blood. Erythritol appears to be causing blood platelets (血小板) to clot more readily. Clots can break off and travel to the heart or the brain, causing a heart attack or a stroke.

Erythritol is a sugar alcohol, a carb found naturally in many fruits and vegetables. However, artificially manufactured in massive quantities, erythritol has become an extremely popular additive to low-carb products.

The discovery of the connection between erythritol and cardiovascular issues was purely accidental. Hazen’s research had a simple goal: find unknown chemicals or compounds in a person’s blood. To do so, the team analyzed 1,157 blood samples. “We found this substance that seemed to play a big role, but we didn’t know it was erythritol, a sweetener until later,” said Hazen. To confirm the findings, the team tested another two batches of blood samples and found that higher levels of erythritol were connected to a greater risk of heart attack, stroke or death within three years.

“This certainly sounds an alarm,” said Dr. Andrew Freeman, director of a hospital inDenver. “Science needs to take a deeper div e into erythritol and in a hurry, because this substance is widely available right now. If it’s harmful, we should know about it.”

Hazen agreed,“I normally don’t get up on a pedestal (崇高地位) and sound the alarm, but this is something that I think we need to be looking at carefully.”

1. About the risk, what does Hazen’s word in paragraph 2 mean?
A.It is not worth considering.B.It is removed by erythritol.
C.It should not be underestimated.D.It is just present in people with disease.
2. What do we know about erythritol?
A.Its quality is uncertain.B.It has been used widely in food.
C.It is manufactured by artists.D.It mainly exists in fruits.
3. What can be concluded from the last two paragraphs?
A.Erythritol is not available to people.
B.Hazen likes warning people about potential dangers.
C.People have realized that erythritol is dangerous.
D.Further research should be done on erythritol.
4. What can be the best title for the text?
A.The Accidental Discovery of a New Sweetener
B.The Potential Health Risks of Erythritol Uncovered
C.The Rise of Erythritol as a Popular Sugar Substitute
D.The Surprising Benefits of Erythritol in Diet Products
