【推荐1】Dogs and horses may not be the closest teammates, but the two animals can have their fair share of fun — at times even playing together and mimicking(模仿)each other's facial expressions, new research suggests. These findings, published in the journal Behavioural Processes, mark the first example of so-called rapid facial mimicry occurring between play partners of different species, and suggest the existence of a universal language of play.

Though the purpose behind play remains unclear, scientists suspect the behavior is to help animals develop hunting and social skills, relieve stress or promote relationships with each other. Learning more about the contexts in which different animals play together could tell researchers a lot about play's origins and development. But apart from a handful of studies featuring humans and their pets, scientists haven't had many chances to analyze examples of interspecies' plays.

In 2018, when someone sent Palagi, an animal behaviorist, a video where a dog and horse play together, interacting with each other fluently, she took the chance to investigate further. The two species were good choices for study, because they both could recognize facial expressions in other animals. Gathering a team, Palagi began to collect and analyze hundreds of other videos where canines(犬类)and equids (马科动物) played together.

At last, 20 videos were picked out: showing animals freely playing on their own, for at least 30 seconds, without human involvement. In the videos, dogs and horses often mimicked each other's moves, jumping, pushing and even biting slightly and naughtily at each other. They also put themselves in weak and easily attacked positions, such as rolling on their backs, displaying their throats and stomachs — a strong sign that they were at ease and even showing their friendliness.

The two creatures also frequently mimicked each other's facial expressions, both adopting the relaxed, open mouths — a behavior that's been noted in wild, social primates(灵长类动物)，but never between a pair of animals of different species.

【推荐2】Honeybees can't swim, and when their wings are wet, they can't fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings to produce little waves and slide toward land-like surfers who create and then ride their own waves.

As with many scientific advances－Isaac Newton's apple or Benjamin Franklin's lightning bolt－Dr. Roh's experiment began with a walk. Passing Caltech's Millikan Pond in 2016, he observed a bee on the water's surface producing waves. He wondered how an insect known for flight could push itself through water.

Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect local Pasadena honeybees and observed their surf-like movements. The researchers used a wire to restrict each bee's bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is about three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It's a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.

The researchers said the surf-like movement hasn't been documented in other insects and most semiaquatic (半水生) insects use their legs for propulsion (推进力), which is known as water-walking. It may have evolved in bees, they predicted.

Dr. Roh and Dr. Gharib have imagined many practical applications for bees'surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can't send a boat or helicopter,” Dr. Gharib said.

【推荐3】Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive because of warming oceans from climate change.

Scientists studied epaulette sharks, which live off Australia and New Guinea. They found that warmer conditions sped up the sharks’ growing process. That meant the sharks were born earlier and very tired. The findings could be used in the study of other sharks, including those that give birth to live young.

The scientists studied 27 sharks. Some were raised in average summer water temperatures, about 27 degrees Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures. They also showed reduced energy levels.

Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies that look like decorations on some military clothing.

One study this year found that worldwide numbers of oceanie sharks and rays dropped more than 70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten shark.

Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia. She was the lead author of the epaulette shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong enough to survive for long in the wild.

She added that if the sharks are born smaller than usual “they are probably going to have to start looking for food sooner—and they’re going to have less time to adjust to their surroundings.” The study should serve as a warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.

1. In what aspect do the warmer conditions affect the baby sharks?

A．Their food.

B．Their body weight.

C．Their living habits.

D．Their moving route.

2. How did the scientists carry out their study?

A．By studying former data.

B．By tracking sharks in the wild.

C．By collecting information about climate change.

D．By comparing sharks in waters of different temperatures

3. What does paragraph 5 mainly talk about?

A．The origin of sharks’ names.	B．The sharks’ appearance.
C．The threats to sharks’ survival.	D．The sharks’ living environment.

4. Which of the following can be the best title for the text?

【推荐1】Sometimes I have to admire people’s imagination but what I admire most is the businessmen’s sense of smell. China’s Singles Day, which falls on Nov. 11 every year, has far surpassed its U.S. counterparts of Black Friday and Cyber Monday—combined. Last year, Americans spent a record $12.8 billion online between Thanksgiving Day and Cyber Monday. It’s impressive until you compare it to the $17.6 billion in sales made by Chinese consumers in a single 24-hour period during 2016’s Singles Day.

Singles Day is known as “Bare Sticks Day” or “Bare Branches Day” in Chinese—because the date “11/11” looks like bare branches and “one” is the loneliest number. Singles Day began in the early 1990s in the dorm rooms of Nanjing University when a group of single friends were sorry about the lack of significant others and decided to mark the day by organizing activities as a group of singles and reducing their loneliness by buying themselves a gift.

Then in 2009, sensing s break between the sales period of China’s National Day on Oct. 1 and Chinese New Year in late January or early February, Alibaba’s Jack Ma saw an opening: sell to comfort lonely hearts.

The first year did only $7.5 million in sales, but just 8 years later, shoppers spent $25.3 billion, or 168.2 billion yuan, this year—a 40 percent jump from last year’s $17.6 billion. Foe comparison, Black Friday and Cyber Monday in the U.S. only netted $6.79 billion in 2016. Amazon doesn’t release sales figures for July’s Prime Day, but it’s pretty safe to believe the not-quite-national-holiday doesn’t come close to $25 billion.

“More than $25 billion in one day is not just a sales figure,” Alibaba Group CEO Daniel Zhang said in a statement. “It represents the desire for quality consumption of the Chinese consumer, and it reflects how merchants and consumers alike have now fully accepted the combination of online and offline sales.”

1. What does the underlined word “others” refer to in Paragraph 2?

A．Roommates.	B．Good friends.
C．Boyfriends or girlfriends.	D．Relatives.

2. What is the original purpose of China’s Singles Day?

A．To promote the online sale of goods.

B．To reduce loneliness of singles in China.

C．To create a holiday for all Chinese youth.

D．To find boyfriends or girlfriends for singles.

3. China’s Singles Day became consumers’ day in ______.

A．2009	B．2016
C．2017	D．the early 1990s

4. Which of the following words can describe Daniel Zhang’s attitude to online sales?

A．Confused.	B．Optimistic.

【推荐2】A fellow speaker from California named Geri flew to Japan, in her favorite jeans and a casual jacket, to give her first speech. Fourteen hours later, four perfectly dressed Japanese gentlemen greeted her at Narita Airport. Smiling and bowing low, they handed her their business cards. With her bag in one hand, Geri took their cards with the other. She thanked them, glanced briefly at the cards, and put them into her jeans pocket quickly.
When the five of them arrived at the hotel, they invited Geri to tea in the lobby (大厅). While sipping tea, the gentlemen presented her with a small gift which she eagerly opened. She was thrilled with the gift and shouted excitedly, “Oh, it’s beautiful!”
At this point, the four Japanese gentlemen stood up and, bowing only very slightly, said “Sayonara” and left immediately. Poor Geri was left astonished. What did she do wrong?
Everything! Her jeans were the first gaffe. Even if you’re coming off a bicycle in Japan, you do not meet c1ients (客人) casually dressed. The second mistake was Geri’s handling of their business cards rudely. In Japan, the business card is one of the most important communicative tools. It is always presented and accepted respectfully with both hands. However, Geri put their cards away much too quickly. In Japan, people use business cards as a conversation starter. You chat about each other’s cards and work and do not put theirs away until they gently and respectfully place yours in safekeeping. Putting it carelessly into her jeans pocket was the ultimate disrespect.
Then, the fourth horror of horrors was that Geri should not have opened the gift in front of her clients. In a land where saving face is critical, it would be embarrassing to discover the gift they gave was not as nice as the one they received. What is worse, Geri hadn’t even given them a gift!
1. In the four Japanese gentlemen’s eyes, Geri took their cards _____________.

【推荐1】For many people, finding an unattended wallet filled with £400 in cash would be a source of temptation (诱惑). But the urge would no doubt be greater if you were living on the streets with little food and money. All of this makes the actions of the homeless Tom Smith even more remarkable.

After spotting a wallet on the front seat inside a parked car with its window down, he stood guard in the rain for about two hours waiting for the owner to return. After hours in the cold and wet, he reached inside and pulled the wallet out hoping to find some ID so he could contact the driver, only to find it contained £400 in notes, with another £50 in spare change beside it.

He then took the wallet to a nearby police station after leaving a note behind to let the owner know it was safe. When the car’s owner John Anderson and his colleague Carol Lawrence returned to the car, which was itself worth £35,000——in Glasgow city center, they were shocked to find a policeman standing next to it. The policeman told them what Mr. Smith did and that the wallet was safe.

Mr. Anderson said: “I couldn’t believe that the guy never took a penny. To think he is sleeping on the streets tonight when he could have stolen the money and paid for a place to stay in. He thought about others instead. It’s unbelievable.”

Mr. Smith’s act drew much of the public's attention. He also won praise from social media users after Mr. Anderson posed about the act of kindness on Facebook. Now Mr. Anderson has set up an online campaign to raise money for Mr. Smith and other homeless people in the area, which by yesterday had received £ 8,000. “I think the faith that everyone has shown in him has touched him. People have been approaching him in the street; he’s had job offers and all sorts,” Mr. Anderson commented.

【推荐2】In 2015, Professor Wang Zhenyi, who specializes in treating acute promyelocytic leukemia (APL) (急性早幼粒细胞白血病), received a letter of thanks from America. The writer of the letter was Mrs. Berna- dette Giandomenico, who once suffered from APL but was cured with all-trans-retinoic acid (ATRA) (全反式维甲酸), a treatment developed by Wang and his medical team.

Working at Ruijin Hospital, Wang has been devoting his life to the treatment of leukenia. He received the country’s highest honor in science and technology in 2010.

Born in 1924 in Shanghai, Wang was inspired by a family friend’s experience of pursuing a career in medicine as a child. His grandmother’s death caused by typhoid (伤寒) further strengthened his resolve (决心) to fight against diseases and rescue patients. With outstanding academic performance, Wang became a doctor at Guangci Hospital, today’s Ruijin Hospital,

In 1978, a research paper from Israeli experts gave Wang inspiration on studying how leukemia cells could become normal. His research didn’t progress as expected, though. In 1983, another research paper shed light on his study. As the paper suggested, after being treated with 13-cis-retinoic acid, white blood cells in patients with APL could become normal. Considering the difficulties and high cost of producing a drug made from 13-cis-retinoic acid, Wang’s team decided to replace that ingredient with ATRA, and they verified its positive effect after several months’ experiments. In 1986, the drug was first adopted in treating a five-year-old patient. It turned out successful. After eight years of research, Wang’s team eventually made the first breakthrough in the battle against APL.

To make sure every APL patient could afford the medicine, Wang has not patented (获取专利权) his research result to date. “One cannot be a real doctor if one does not have expertise in medicine,” Wang said in an interview. “However, without a kind heart, a skilled doctor may cause harm to patients.”

Having worked in the field of hematopathology for over 70 years, Wang has been well recognized for his remarkable contribution to saving lives.

【推荐3】Before I turned 10, I lost my parents. I lived alone in a room that a family member allowed me to use rent-free. To support myself, I began to deliver newspapers.

I would be up every morning by 5 am and walk five kilometers to the newspaper office. By 6 am, I would collect 50 copies of Manzil. After distributing (分发) the copies, I would rush home—another 3 kilometers—quickly eat and be off to high school.

One winter morning in 1945, I got home after my deliveries to find a boy of my age at my doorstep. He introduced himself as Afzal and said his father wanted to see me.

I was greeted at the door by Afzal’s mother, Naseem. She served tea and snacks as Afzal’s father, Mr. Kader, joined us. She gently asked me about my daily routine. I told her about my morning job.

Later, as I was about to leave after thanking them, Mr. Kader asked me to wait. Naseem asked me, “How many miles do you walk every day?”

“A little more than six,” I replied.

My reply shocked her. I saw Mr. Kader wheeling a new bicycle.

“This is for you!” he said.

It took a few seconds for the love to sink in. I didn’t realize tears were rolling down my face.

Mr. Kader said, “Your newspaper editor is a friend of mine. He gave me your address, so I knew you lived close by. Then Afzal told us more about you.”

I bowed, gratefully, shook hands with Afzal and left. This time I did not have to walk—I had the bicycle.

The bicycle saved my life for many years thereafter and taught me a lifelong lesson: Help should always be need-based. Never try to feed a person who is dying of thirst.

【推荐1】Tunnels are passageways that are built under the ground. They can also be made under a sea or a river. Some tunnels are dug through high mountains.

For hundreds of years，tunnels have been built all over the world. People use these tunnels to travel from one place to another. Some tunnels are used as waterlanes. Coal and gemstones are also brought from under the ground through long tunnels.

In the past，people dug tunnels using picks and shovels. Rocks and soil were loaded into one-wheel barrows and then onto horses and carts. This work was very tiring.

Today，engineers do a lot of planning before they start to build a tunnel. They use computers to check the level of the water and the types of rock under the ground. When they are sure the area is safe，huge machines are used to dig out the soil.

These machines have an enormous cutting wheel at the front. The wheel slowly grinds（磨碎） through the rock and soil to make the tunnel. Soil that is not needed is carried away in large trucks. As the tunnel becomes longer，it is lined with huge pipes so the walls and roof do not callapse.

Long tunnels have powerful lights to help drivers see the road ahead. Water sprinklers（洒水装置）are fitted to help keep people safe if a fire breaks out in the tunnel.

In large cities，tunnels are built under very busy roads. ，People can drive through these tunnels. This makes it quicker to travel to different parts of the city.

Some trains have to wind slowly and carefully over steep mountain slopes. But，in places where there are tunnels，trains can travel quickly through the mountain to reach the other side.

1. Why do people build the tunnels in big cities?

A．To explore the underground world.

B．To exhibit engineering skills.

C．To draw water from the underground.

A．People dig tunnels with heavy machinery instead of simple tools.

B．People don't need to deal with the soil from digging now.

C．To keep safe, computers will do everything for people.

D．People use huge pipes for all tunnels for safety reasons.

3. What do the last two paragraphs serve as?

【推荐2】It’s not possible to stay together with loved ones all the time. Sometimes family members have to be far away from each other. During that time, they might face something terrible. Although we know what they are suffering, being far away makes it harder to help and comfort loved ones. There is no use worrying a lot about them. Instead, keeping a positive attitude of support is more helpful than getting into worrying about the person. I think it is what I can do to help my loved ones.

My daughter has been working full-time during summer about 10 hours a day. She has to study hard for a big entrance exam. At first, like most people, I wanted to try to solve the problems and try to explain the situation. Was there a better way of time management? Was there a better way of studying for this test? However, that was not always helpful. Sometimes, it even gave more pressure to her. Sometimes it might sound like there was something wrong to improve However, it was just tiring at the end of the day. What would be the kind thing to do in this situation? It was hard to read someone’s mind. I decided to just chat with her online and to send a hug emoji (表情符号) this time. It seemed more suitable than talking about solutions. Giving space can also be an act of help, comfort and kindness

【推荐3】To many people, honey bees symbolize wealth, sustainability and environmentalism. But as a honey bee researcher, I have to tell you that only the first item on that list is defensible. Although they are important for agriculture, honey bees, which are usually imported from outside the local area, also disturb natural ecosystems by competing with native bees.

For several years the media has told us that bee populations are under threat. In response to this media campaign to"save the bees", raising honey bees has become a popular hobby. But as a species, honey bees are least in need of saving. Much media attention is given to honey bees at the expense of native bees, and this has led many citizens—myself once included—to mistakenly believe they are doing a good thing for the environment by raising honey bees. Unfortunately, theyare probably doing more harm than good.

“Beekeeping is for people; it's not a conservation practice, "says Shelly Smith, an environmental science professor. People mistakenly think keeping honey bees also helps the native bees, which are at risk of extinction. That's wrong.”

Smith and her research team recently surveyed one thousand local people in Canada and found that they had a surprisingly poor understanding of bee types and their roles in promoting flower growth. Most people’s attention is on saving honey bees when, from a conservationist's point of view, native bees are the ones in more need of support.

“To make matters worse, beekeeping companies and various non-science-based projects have financially benefited from the decline of native bee populations, "Smith explains. "These companies pretend they are interested in saving bees but their actions are actually damaging the native bee populations.”

The introduction of honey bees increases competition with native bee populations for food,putting even more pressure on the wild species that are already in decline. Honey bees are extremely efficient food gatherers and take over almost all local flower resources, thus leading to damaging competition—that is, where one species uses up a resource, not leaving enough to go around.

1. Which statement does the writer argue for?

A．Honey bees endanger native bees.

B．Honey bees are a symbol of wealth.

C．Honey bees are important for agriculture.

D．The media campaign has failed to promote honey bee businesses.

3. What surprised Shelly Smith's team?

A．Beekeeping companies' making great profits.

B．The quick expansion of bee-friendly habitats.

C．The public's ignorance of bee varieties and roles.

D．Insufficient attention given to saving honey bees.

4. How does the writer develop the last paragraph?

A．By listing examples.	B．By making comparisons.
