1 . Physical education, or gym class, isnˈt required for all high school students. In some schools, it isnˈt offered for some different reasons. But should high school students have physical education? The answer is certainly "yes".
Today many people donˈt do sports. But as is known to all, doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.
High school isnˈt that easy. Many students are under a lot of stress. Stress can be harmful to a studentˈs studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.
Inactivity increases teensˈ risk of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 per cent of health care spending goes towards treating medical conditions that can be hindered by lifestyle changes, according to the American College of Sports Medicine.
According to the Presidentˈs Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activity each week improved their academic (学业的) performance. Students from programmes with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.
1. According to Paragraph 2, what does physical education in high school mean?| A．Helping teens learn to make good plans. |
| B．Removing the stress faced by teens at school. |
| C．Making teens pay attention to exercise later. |
| D．Getting teens to encourage adults to exercise. |
| A．Measured. | B．Prevented. |
| C．Shown. | D．Caused. |
| A．means making students choose between sports and studies |
| B．helps students make good use of all their time |
| C．means students adjust to their studies better |
| D．helps students do better in their studies |
| A．How high school students can live a better life. |
| B．How schools can help students love doing sports. |
| C．Why some schools consider physical education important. |
| D．Why high school students should receive physical education. |
2 . Everybody hates rats. But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be the new best friends of humans.
What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “Robots’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs and unlike robots, they don’t need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to and a rat would get out if it wasn’t safe.” Perhaps for the first time in history people will be happy to see a rat in a building.

3 . Jack was born without eyes. He was very lucky as he grew up having other kittens (young cats) to socialize (交往) with, and was used to people from the moment he was born. However, when it came time to find the kittens homes, no one knew where Jack would end up.
That’s when I got an e-mail from my friend. All she asked was “Do you still want one of the kittens? There’s one here with no eyes and no one would like to take him”. Without thinking I told her that I did want the kitten.
When we first brought him home, Jack stayed mostly in my room. After about a day he had no issues running around and climbing on everything. At times he gets lost in the house, he’ll stop. But we just call his name and talk to him and it isn’t long before he finds his way back to us.
A few weeks after getting Jack, we got a new cat named Bear. Jack and Bear have become best friends. It doesn’t matter that he can’t see. He always knows when Bear is around. He’ll run across the yard straight to Bear and wrap his front legs around his neck in a big hug. They run after each other around and wrestle (摔跤). They’ll lie down in the grass together when tired.
Jack is truly an inspiration. I’ve owned lots of kittens in my life, but Jack is the happiest and most playful. He doesn’t feel sorry for himself. He doesn’t need pity. I think Jean, owner of Gumbo, another eyeless cat, said it best when she told me that cats don’t have disabilities; they have adaptability.

4 . Amid a global pandemic, another disaster was unfolding early this year beneath the ocean waters off the coast of Australia. Thanks to climate change, surface water temperatures across the Great Barrier Reef had hit record highs. By April, the damage was clear: the reef (礁) had experienced the most widespread bleaching event ever recorded and ended up disappearing, as corals expelled what serves as their food source and give them their color.
With a quarter of all ocean fish depending on reefs during their life cycles, scientists say we urgently need to reduce greenhouse-gas emissions to preserve the essential habitats. “Unfortunately we aren’t acting quick enough on climate change, and that leaves a real problem for coral reefs,” says Emma Camp, 33, a marine biogeochemist at the University of Technology Sydney. She’s investigating special corals that survive in forest lagoons (环礁湖) where water is warmer and more acidic compared with that surrounding most reefs, and which may be resistant to the conditions ruining the Great Barrier Reef.
Camp wants to learn if these creatures-named “supercorals” after she and a team discovered them during research for her Ph.D. in 2014-can be transplanted to other reefs to aid restoration.
She’s also investigating the biochemical characteristics that allow certain corals to survive in extreme environments. None of her efforts, she says, is a substitute for action to stop climate change. “My research is really about buying time.”
For Camp, it’s also essential to include a new generation of scientists to study the planet’s ecological systems. She talks about science with students around the world and speaks at local and international women-in-science events. “Our research tells more than itself. It is clear that if we lose 50% of the intellectual input because we’re filtering out women from that career path, we’re really going to struggle to solve those problems,” she says.
1. What’s the main concern according to the first paragraph?| A．The reef died out in great number. | B．The reef began to change color. |
| C．Climate change went beyond expectation. | D．Corals had no source of food. |
| A．Influenced. | B．Accepted. | C．Dismissed. | D．Adopted. |
| A．They suffer due to our slow response to the climate change. |
| B．They stand out by providing a good condition for reefs. |
| C．Their water has a big influence on the reef’s growth. |
| D．Their warmer and acidic water is the curse of the climate change. |
| A．It has served its purpose of restoring other reefs. |
| B．Her efforts will encourage people to deal with climate change. |
| C．Her efforts only put off the consequence of warm surface water. |

5 . There is a very long list of rules for the New York City subway. Don’t put your feet on a seat, don’t carry open cups of coffee or soda, don’t take more than one seat... Those are just a few of the rules. There are hundreds more.
With so many rules, why is it still unpleasant to ride the subway?
Some people think that the problem is that no one enforces the rules. Other passengers sometimes try to enforce rules. But you can’t rely on them because New Yorkers have unwritten rules against talking to strangers and making eye contact with strangers. How can you tell someone to take her shopping bags off the seat and throw away her Coke without talking to her or looking at her? It is difficult.
There are other New Yorkers who think that the subway is unpleasant because there are not enough rules. One rider wrote a letter to The New York Times a couple of weeks ago suggesting a few more subway rules. Here are some of the rules that she would like to see:
—Don’t lean on the poles. You prevent other people from holding on. They can fall down.
—Talk quietly. The trains are already too noisy.
—Give your seat to elderly passengers or to parents with small children.
If those unwritten rules of etiquette are written down, will the rude people be more likely to follow them? It doesn’t make sense to make more rules that no one will enforce.
The real problem is that we are forgetting how to be nice to each other. It is embarrassing that we need a rule to tell us to give our seat to elderly passengers. Nobody should need to be reminded to do that.
I say we stop talking about the rules and try to remember our manners. Let’s be nice to each other not because a police officer might tell us to get off the train, but because it is the right thing to do. Then New York City would be more civilized —both above ground and below.
1. Don’t make eye contact and don’t talk to strangers are examples of .| A．New York subway rules | B．personal preferences on the subway |
| C．behavioral habits in New York City | D．unpleasant experiences on the subway |
| A．manners | B．phenomena | C．festivals | D．moods |
| A．The authority should set stricter rules. |
| B．The government should employ more police. |
| C．The citizens should ride the subway less. |
| D．Everyone should take better care of their behavior. |
6 . It doesn’t take a lot to live a healthy live. That parents often have family meals with their children ranks first.
A Harvard study found that families that eat together are twice as likely to eat their five servings of fruits and vegetables a day as families who don't eat together. Families also eat less fried food when they eat together. Finally, children who regularly eat with family have diets higher in fiber, calcium, iron, and vitamins B6, B12, C and E.
During family meals, parents can set a good example of healthy eating that children may follow. They also display polite table manners. Family meals teach children important skills.
When a family eats together, kids can learn about nutrition and healthy eating. In many studies of school-aged children, those who eat family meals have a higher level of nutrition knowledge.
When a family eats together, kids learn about food safety, like hand washing before eating.
Children who have company at meals are slimmer than those who eat alone. That's because they eat less, eat more slowly, and talk more. This is a good way to deter obesity in children.
Family meals can help children build vocabulary. Studies showed kids who ate with their families performed better at school and had a broader vocabulary. Family meals offer an opportunity for conversations where kids learn vocabulary-building words to help them read and communicate better.
Children gain a better sense of belonging within the family when they eat together with their parents at home. Family meals offer a time for a family to come together as a group and develop a feeling of belonging. That sense of belonging leads to better self-esteem（自尊）. In conclusion, family meals are very important.

7 . Sales of Apple’s new iPhone 11 in China began on Friday, but were met with a cooler reception from consumers than in previous years. Unlike in previous years, no long lines were seen outside Chinese shops on Friday for the new iPhone, and the product release only made the headlines in a few media outlets.
Huawei unveiled its Mate 30 smartphone series on Thursday night. Its new devices have won consumers’ hearts at home and abroad. Many compared it with Apple’s new iPhone 11, saying that beats the new iPhone in terms of innovation and quality. One customer surnamed Zhao, an IT specialist who pre-ordered a Mate 30 Pro on Friday, said that he chose Mate 30 without hesitation. Zhao said, “It’s obvious that Huawei’s new phone with its advanced 5G mode would lead the future global telecommunications market, and its new innovative features in gesture and side control attracted my attention, too.”
In contrast with iPhone 11’s lukewarm sales, Chinese netizens have engaged in discussions on Mate 30 and Mate 30 Pro. An online poll on the Mate 30 and iPhone 11 on Weibo on Friday showed that more than 60 percent of netizens chose the Mate 30, while less than 20 percent chose the iPhone 11. Many chose Huawei not out of patriotism but for its technology.
Overseas consumers also engaged in vigorous discussions on Huawei’s new flagship devices on technology sites and social media platforms. On Twitter, many netizens said “nice”, “best phone ever” and “my favorite one” on Huawei’s Twitter account. Some netizens in countries like the UK, the Netherlands and Argentina asked when Huawei’s new devices would be released in their countries.

8 . Parents who have books in the home increase the level of education their children will attain(获得), whether rich or poor, according to a 20-year study led by Mariah Evans.
For years, educators have thought the strongest predictor(预示物) of attaining high levels of education was having parents who were highly educated. But, the study showed that the difference between being raised in a bookless home compared to being raised in a home with a 500-book library has as great an effect on the level of education a child will attain as the difference between having parents who are barely literate (有文化的) and having parents who have a university education.
Being a sociologist, Evans was particularly interested to find that children of less-educated parents benefit the most from having books in the home. What kinds of investments should we make to help these kids get ahead? The results of this study indicate that getting some books into their homes is an inexpensive way that we can help these children succeed. Evans said, “Even a little bit goes a long way. Having as few as 20 books in the home still has a significant impact on motivating a child to a higher level of education, and the more books you add, the greater benefit the children get.”
The researchers were struck by the strong effect having books in the home had on children's educational attainment even above and beyond such factors as education level of the parents, the father's occupation or the economic level of the country.
Having books in the home is twice as important as the father's education level, and more important than whether a child was brought up in a developing country or a developed country. Surprisingly, the difference in educational attainment for children born in a developed country and children born in a developing country was just 2 years, less than two-thirds of the effect that having 500 or more books in the home had on children.
1. In the past educators held a point of view that ______ .| A．children whose family had a library would possibly attain high levels of education |
| B．children who were born in poor families studied harder than those in rich families |
| C．children whose parents are highly educated would attain high levels of education |
| D．parents’ level of education had nothing to do with their children’s levels of education |
| A．Making somebody want to do something. |
| B．Helping somebody to finish something |
| C．Making somebody pretend to do something. |
| D．Preventing somebody from achieving something. |
| A．The economic level of the country. | B．The father’s occupation. |
| C．Education levels of parents. | D．Having books in the home. |
9 . It was the final climb on his search to reach the highest top on all seven continents. When Christopher Kulish finally reached Mount Everest’s 29,035-foot peak, he joined an elite group known as the “Seven Summits Club”(七峰俱乐部). But the 62-year-old Colorado attorney died suddenly Monday after returning to the first camp below the mountain’s summit. He’s the second American to die in the past week after reaching Everest’s highest point. His family believes the cause was a heart attack, according to theDenver Post. “He saw his last sunrise from the highest peak on Earth,” his brother, Mark Kulish, said in a statement to the Denver Post. “We are heartbroken at this news.”
Last week, 55-year-old Donald Lynn Cash of Utah collapsed and died just after reaching the Everest peak. He too had reached the highest point on all seven continents. Including Christopher and Cash, at least 11 people have died on Mount Everest this year.
The deaths come among reports of overcrowding on the popular mountain. The Nepali government granted a total of 381 permits to climb Everest this year, a number that doesn’t include guides who are on the mountain as well. For some climbers, that traffic has meant longer wait times — some told the Himalayan Times the wait has been over two hours between the last camp and the peak. Mountaineer Vanessa O’Brien, who has also climbed the seven summits, said when there’s a crowd, being a more experienced climber won’t help you. “It doesn’t matter if you’re the best racecar driver in the world. If you’re stuck in traffic, you’re stuck in traffic,” she said in an interview.
And when a climber is stuck in that traffic, “their body is starting to deteriorate（恶化）.” O’Brien, who set a record as the fastest woman to reach the highest peak on every continent, also said the descent(下降) is often harder than the climb.
Climbing expert Alan Arnette said there’s no simple explanation for the string of deaths. He said weather that has led to a shorter climbing season is one factor causing overcrowding. He also said the cost to climb Mount Everest has decreased, which means more people are making the journey. He urged the governments in charge of granting(同意）permits to limit how many people can be on the mountain at once.
Still, Christopher was no beginner. His family said he’d been mountain climbing for five decades. He arrived at the base camp nearly two months before his climb so he could give himself time to adapt to the conditions. When he made his journey, his family said he was climbing with a small group in almost ideal conditions after some of the overcrowding had cleared.
His brother described being a lawyer as a “day job” for Christopher. Climbing was his love. “He was an inveterate climber of peaks in Colorado, the West and the world over,” Mark Kulish said. “He passed away doing what he loved.”

10 . 
“What kind of rubbish are you?” This question might normally cause anger, but in Shanghai it has brought about complaints over the past week. On July 1st, the city introduced strict trash-sorting regulations that are expected to be used as a model for our country. Residents must divide their waste into four separate kinds and put it into specific public bins. They must do so at scheduled times, when monitors are present to ensure compliance（服从）and to inquire into the nature of one’s rubbish.
Violators face the possibility of fines and worse. They could be hit with fines of up to 200 yuan ($29). For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain bank loans or even buy train tickets.
Shanghai authorities are responding to an obvious environmental problem. It generates 9 million tonnes of garbage a year, more than London’s annual output and rising quickly. But like other cities in China, it lacks a recycling system. Instead, it has relied on trash pickers to sort out the waste, picking out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up. China produces 80 billion pairs of disposable(一次性的)chopsticks a year.
Many residents appear to support the idea of recycling in general but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous（有害的）, the differences among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and toss it by hand. Most upset are the short windows for throwing trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.
1. What does the underlined word “Violators” in Paragraph 2 refer to?| A．People who don’t sort the waste. |
| B．People who argue with the monitors. |
| C．People who don’t throw the trash on time. |
| D．People who are against the regulations. |
| A．The massive traffic. | B．The increasing garbage. |
| C．Lack of a recycling system. | D．Lack of trash pickers. |
| A．Complex distinction among the four categories of trash. |
| B．Short scheduled time for throwing the trash. |
| C．Being observed by monitors when throwing the garbage. |
| D．Being fined when blamed due to improper behavior. |
| A．A Restart of Trash-sorting | B．A Great Change in Tackling Litter |
| C．New Times of Garbage Classification | D．A Craze for Learning Waste Sorting |
