1 . Men hunted.Women gathered. But the discovery of a woman buried 9,000 years ago in the Andes Mountains with weapons and hunting tools challenges this widely accepted view. The woman, thought to be between 17 and 19 years old when she died, was buried with items that suggested she hunted big-game animals by spear (矛) throwing.
The objects accompanying people in death tend to be those that accompanied them in life. Although some scholars have suggested a role for women in ancient hunting, others have dismissed this idea even when hunting tools were uncovered in female burials.
To examine whether this woman found at this site was an exception, the researchers examined 429 skeletons at 107 burial sites from around 8,000 to 14,000 years ago. Of those, 27 individuals were buried with hunting tools—11 were female and 15 were male. The sample was sufficient to “justify the conclusion that female participation in early big-game hunting was likely nontrivial,” said lead study author Haas.
The findings add to doubts about “man-the-hunter” assumption about early humans since the mid-20th century. That theory assumes that it was men who went out and hunted, bringing home meat to feed women and children, who were responsible for gathering berries, plants and nuts to enrich the dict.
But recent research suggests hunting was very much a community-based activity, needing the participation of all able-bodied individuals to drive large animals, the study said. Meanwhile, the spears used at that time had low accuracy, encouraging participation, and using it was a skill learned from childhood. Women may also have been freed from child care demands by “allo-parenting”—raising children was a job shared by many.
“Our findings have made me rethink the most basic organizational structure of ancient hunter-gatherer groups, and human groups more generally,” Haas said.

2 . A New Jersey couple and a homeless man have been accused of making up a feel﹣good story that raised more than ＄400,000 through GoFundMe.
The couple, Kate McClure and Mark D'Amico, and the man, Johnny Bobbitt Jr., face a charge of second-degree theft, Burlington County Prosecutor Scott Coffina said Thursday.
The couple said they met Bobbitt when he gave his last ＄20 to McClure, who was stranded on Interstate 95 in Philadelphia, so she could put gas in her car，then started the GoFundMe campaign as a way to thank him.
The paying-it-forward story that drove this fundraiser might seem too good to be true, Coffina said at a press conference.
Unfortunately, it was. The entire campaign was based on a lie.
After fees, the money of the campaign netted about ＄367, 000, all deposited into McClure's accounts, Coffina said. Bobbitt received ＄75,000, and within months McClure and D'Amico had wasted their share on buying a car, high-end handbags and trips, Coffina said. They also used it at casinos(赌场), he said.
Coffina stressed that while Bobbitt, a veteran (老兵), deserves thanks for his service to the country and sympathy for his situation; he was fully involved in the crime, using media to help "promote the dishonest campaign".
According to Coffina, McClure and D'Amico first met Bobbitt at an off-ramp（驶出匝道）near a casino they regularly went, at least a month before the GoFundMe campaign went live.
They went back to the spot a month later, Coffina said. D'Amico took a picture of McClure and Bobbitt that became the face of the GoFundMe campaign that they started hours later, Coffina said.
1. What's the actual purpose of the GoFundMe campaign started by the couple?| A．To express their appreciation for Bobbitt's help. |

3 . What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.
1. We can infer from the first paragraph that ________.| A．we should think about how to find our career |
| B．learning ability at school shows power in your job |

4 . I made an important decision when I was in Junior 3.
Before I made that decision, I was one of the boys who tried too hard to act as an adult. I didn't know that only kids want to show themselves as adults.
I didn't listen to my parents and teachers, and my grades became poor. Then came the high school entrance exam.
At the turning point of my life, my mom wanted to have a conversation with me. I wanted to turn it down but when I looked at her eyes, I felt I couldn't refuse. Instead of asking me to study hard, to my surprise, Mom just asked what I wanted to do in the future. Without thinking too much, I just said I would like to study hard.
Mom smiled and asked again: “I asked: what do you WANT to do？”
I never seriously thought about the question. So, I kept silent.
“Whether you want to go on studying or enter the society, ” she went on, “it is your own decision. Your life should be decided by you, not by anyone else, including me.” After saying that, she had tears in her eyes.
For the first time in my life, I was asked to make my own decision. I sat in my chair and thought about myself, my life and what kind of person I wanted to become.
It took me what seemed to be ages to make the biggest decision so far in my life—I wanted to be a man who makes a difference in the world. To achieve that, I needed to study hard.
The path to my future became clear to me. I didn't act rebelliously any more. With passion in my heart, I studied hard. Now, I'm one of the best students in the class.
Thanks to that decision, I have become what I am today.

5 . It might seem strange to be making predictions about 2021, but one thing is clear: technology has been affected just as much as every other part of our lives. Another clear thing is that today’s most important technology trends will play a big part in helping us deal with and adapt to the many challenges facing us. From the shift to working from home to new rules about how we meet and interact in public spaces, technology trends will be the driving force in managing the change.
One of the major technology trends that are likely to play out this year is 5G and enhanced connectivity. Each successive advance in mobile connectivity from 3G onwards has unlocked new use cases for the Internet. 3G made web browsing and data-driven services useful on mobile devices, 4G led to the growth of streaming video and music platforms as bandwidths (宽带) increased, and 5G, similarly, will open more doors in terms of what is possible.
5G means that services relying on advanced technologies such as augmented (增强的) reality and virtual reality, as well as cloud-based gaming platforms like Google’s Stadia, become a practical thing, anywhere at any time. They also threaten to make cable and fiber-based (光纤) networks redundant, with their need for us to be tied to a particular location.
In short, 5G and other advanced, high-speed networks make other new technologies available anywhere, any time. A great example is Norwegian fishery operator Salmar that uses a 5G network to automate the care and feeding of its fish. Image recognition algorithms (算法) are used to detect which fish are over or under-feeding, and automatically distribute food and medicine needed to keep them healthy. Initiatives like this will become increasingly important during 2021, where businesses look to increase automation across their workforces.
1. Which of the following is highly influenced by 5G technology?| A．Data-driven services. | B．Streaming video. |
| C．Music platforms. | D．Google’s Stadia. |
| A．Useful. | B．Unnecessary. | C．Expensive. | D．Special. |
| A．To show the development of Norwegian fishery. |
| B．To explain how to keep fish healthy. |
| C．To present the application of 5G technology. |
| D．To propose new initiatives for businesses. |
| A．Different predictions of technology trends. |
| B．Successive advances in mobile technology. |
| C．One of the technological highlights of the year. |
| D．The driving force in managing changes. |
6 . Today’s students have a problem. They were born into a world where technology, smartphones, and immediate access to the Internet are hurting their ability to focus and changing the way they think.
Now teachers have a problem too. They find it particularly exhausting to ask students to read complex or long texts without taking regular breaks. Smartphones have clearly affected the younger generation, but how education should evolve for digital-native students?
A common idea among teachers is that short is good. When students can’t seem to pay attention to long lectures, many teachers simply break lessons into smaller patterns. In fact, students need time to engage with a topic once the teacher introduces it before moving on. Switching between small lessons too quickly could rob them of valuable comprehension.
There are also teachers who begin classes with meditation (深思) exercises to help their students focus. However, it turns out that any sort of “tech breaks” could counteract strong desires to multi task.
A 2018 study found that students aged between 10 and 24 tend to stay away from physical books. They prefer video as a source of information second only to teachers. Therefore, some tech-forward teachers choose platforms such as YouTube and Instagram. Asha Choksi, vice-president of global research at Pearson, gives the example of a teacher who films himself performing a science experiment and posts it to YouTube. When it is time for class, he uses the video to illustrate material in the textbook, which can seem boring to students.
Still, while those educators are embracing technology in the classroom to meet student’s needs, they also find value in traditional methods, and so suggest a “blended (混合的) learning” approach. Direct instruction from them will never be replaced in their classes. Technology will be favored only when it improves a lesson in ways that are impossible offline.
Digital natives will continue to eagerly adopt new media. Teachers have no choice but to evolve. They are making an effort not only to ensure that students can take advantage of new technologies, but to teach students valuable skills that can help them think in a world constantly trying to distract them. Think of the Zuckerbergs, the Gates, the Jobs and all those pioneers in the tech world. They became successful not because they could code (编程); it was because they could think.
1. What does the underlined word “counteract” in paragraph 4 probably mean?| A．Motivate. | B．Reduce. | C．Compensate. | D．Influence. |
| A．Teachers adopt short lectures, small lessons, which could be hard to understand sometimes. |
| B．Teachers employ meditation exercises to help students concentrate on class, which is of little effect. |
| C．Students aged between 10 and 24 don’t prefer physical books, so YouTube and Instagram may be a good choice. |
| D．Students aged between 10 and 24 prefer videos to teachers, so using videos to explain textbooks is a popular way. |
(1). the conventional way of teaching remains unchallenged
(2). technology is a useful supplement to textbooks
(3). material in the textbook is too boring to most students
(4). teachers want to change their traditional teaching methods
| A．(1)(2) | B．(2)(3) | C．(3)(4) | D．(1)(4) |
| A．to share as much knowledge with students as possible |
| B．to encourage students to make full use of new technologies |
| C．to help students develop their ability to think critically and creatively |
| D．to instruct students to limit their use of smart phones and social media |
7 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

8 . Scientists have been trying to figure out how to alter the genes of humans for many years, and it looks like they’ve finally cracked (破解) the code. But while this may seem like a great step forward in science, some also believe that it’s one step back when it comes to ethics (道德准则). In August, a group of scientists from the USA and South Korea worked together to successfully edit a human embryo (胚胎) and remove a genetic mutation (突变) that would have led to heart disease, reported The Guardian. This was done with the help of CRISPR, a gene-editing tool that allows scientists to “cut and paste” human DNA.
Although this was the first example of an embryo’s genes being changed successfully, the advantages of gene editing have already been tested in living patients. In 2015, a five-month-old girl from the UK was saved after doctors used edited cells to fight off her cancer. As of today, she’s alive and well. And in the USA last year, scientists managed to remove HIV cells from several patients by editing the genes inside their bodies.
Some people hope that in the future, diseases or birth defects could simply be "edited out”. However, others believe this could lead to so-called designer babies, giving parents the option to choose everything from eye color to intelligence. “You could find wealthy parents buying the latest “upgrades” for their children, leading to even greater inequality than we already live with,” Marcy Camovsky, director of the San Francisco Center for Genetics, told BBC News.
In spite of these ethical concerns, experts say it’s not possible to create the “perfect” human being. Despite the progress scientists have made, we don’t understand human genes enough to give all unborn children great brainpower or amazing singing abilities. “Right now, we know nothing about genetic enhancement,” Hank Greely, a director at Stanford University, USA, told The New York Times. “We’re never going to be able to say, honestly, this embryo looks like it would score high on the two-part SAT.”
So it looks like if we want good exam results, or to impress people with our piano skills, we’ll have to stick with the old fashioned method of plain hard work---at least for now.

| A．Gene editing is regarded as the perfect way to treat birth defects. |
| B．There is still a long way to go to fully understand human genes. |
| C．Gene editing could help enhance human intelligence in the near future. |
| D．Scientists are pessimistic (悲观的) about the future of gene editing. |
9 . In many cultures, it is considered unlucky to spill salt. Fortunately, many cultures also have a solution to the problem, which usually involves throwing a pinch of salt over your shoulder. It may seem confusing to modern humans, but knowing that salt was once incredibly valuable can change this perspective.
For thousands of years, salt was an extremely rare commodity. It was difficult to obtain so that the price was very high. Many trading routes were set up to carry salt, people were paid in salt, and salt was sometimes worth more than its weight in gold. Therefore, spilling salt was considered wasteful.
Because of its high value, salt was also associated with friendship and good fortune. Offerings of salt were included in many religious ceremonies, and people might bring salt to a new home for good luck. These associations would have suggested that it would be bad luck to spill salt, since it would seem to violate salt’s fortunate properties.
Salt is also an excellent preservative. It prevents food from going bad. As such, it came to be linked with health and longevity. In some cultures, spilling salt was thought to reduce one's well-being. In Britain, for example, each spilled grain was said to represent a tear, while in Germany spilled salt awakened the devil, bringing misfortune.
The fear of spilling salt was also adopted into the Christian faith. It is said that Judas spilled salt at the Last Supper, and since he later turned out to be the betrayer of Christ, spilled salt is considered unlucky by many Christians.
Should you be unfortunate enough to spill salt, you might throw a pinch over your left shoulder to blind the Devil.
1. Spilling salt was probably thought to bring bad luck because ________.| A．it was a Christian faith | B．salt was linked with misfortune |
| C．it would decrease one’s lifespan | D．salt was always expensive than gold |
| A．Protector. | B．Flavor. | C．Medium. | D．Solution. |
| A．To introduce the history of salt. | B．To show ways to avoid misfortune. |
| C．To explain the beliefs about spilling salt. | D．To entertain readers with some anecdotes. |
10 . One of the most traditional British holidays is the “seaside holiday”. Typically, families get on a train or into a car and travel to British seaside towns. They sunbathe on the beach, buy ice creams, eat fish and chips, build sandcastles and so on.
In the early 1970s, air travel became affordable for the average family in the UK, and more and more British people started travelling abroad for their summer holidays. After all, the British weather isn't very good, even in summer, so a lot leave the UK for a vacation. Particularly popular with families on a budget is the “package holiday", where the cost of flights and accommodation are offered at a discounted price by travel agents.
In the 1980s and 1990s, young people in the UK became more wealthy, or at least had more disposable income. As a result, young people started to go abroad in groups, to places such as Spain and Greece. Once at their destination, they socialized with other groups of young people and had one long party.
British holidaying habits have begun to change, however. Climate change means that the UK now has a warmer climate than before, so people don't always feel they need to go overseas to find good weather. Also, the world seems a less certain place as interconnected economics rise and fall, which means that the cost of foreign holidays is less predictable than it used to be. As a result, more and more Britons are choosing to spend their summer holidays in the UK.
In the UK, the domestic (国内的) tourism industry---when people go on holiday in their own country---is healthier than it has been in decades. There is now an increased appreciation among Britons for the diversity of the UK. It is not just the geography and the diversity of climate-based activities on offer. It is also the diversity of the cultures in the UK that is beginning to be of interest to domestic tourists
The UK has always been famous for its international explorers, but now it is starting to discover itself.
