Liz Payne.BWhat a day! I started at my new school this morning and had the best time. I made lots of new friends and really liked my teachers. I was nervous the night before,but I had no reason to be. Everyone was so friendly and polite. They made me feel at ease. It was l ike I’d been at the school for a hundred years!The day started very early at 7∶00 a.m. had my breakfast downstairs with my mom. She could tell that I was very nervous. Mom kept asking me what was wrong. She told me I had nothing to worry about and that everyone was going to love me. If they didn’t love me,Mom said to send them her way for a good talking to. I couldn’t stop laughing.My mom dropped me off at the school gates about five minutes before the bell.A little blonde(金发的) girl got dropped off at the same time and started waving(招手) at me. She ran over and told me her name was Abigail. She was very nice and we became close straight away. We spent all morning together and began to talk to another girl called Stacey. The three of us sat together in class all day and we even made our way home together! It went so quickly. Our teacher told us that tomorrow we wouldreally start learning and developing new skills.I cannot wait until tomorrow and feel as though I am really going to enjoy my time at my new school. I only hope that my new friends feel the same way too.4. How did the author feel the night before her new school?A. Tired.B. Excited.C. Worried.D. Relaxed.5. What did the author think of her mother’s advice?A. Clear.B. Funny.C. Reasonable.D. Excellent.6. What happened on the author’s first day of school?A. She met many nice people.B. She had a hurried breakfast.C. She learned some new skills.D. She arrived at school very early.7. What can we infer about Abigail?A. She disliked Stacey.B. She was shy and quiet.C. She got on well with the author.D. She was an old friend of the author.CWhat would you like to be when you grow up? A teacher? A doctor? An astronaut? What do you need to do to achieve your dream job?Perhaps you think that studying well and then going on to work hard will get you the successful career you want. We are constantly taught that our hard work will eventually pay off.But a government survey has shown that hard work is not the only thing that will help you to move up the ladder. Two thirds of people believe that who you know matters more than what you know when it comes to social activity. So are the connections that you have more important than your education?Seventy-six percent of the people in the survey believed that family backgroundis important in influencing your chances of success. They believe that if you are privileged from birth, you are more likely to have a successful career, especially if your family is wealthy.Even if you don't have a privileged background, the people you know can still make a difference to your career. Networking is a skill which is encouraged by many career advisers. Some companies run networking workshops to try and encourage staff to meet other people, to communicate and build relationships. It's a valuable skill. But the survey also showed something quite interesting. Although most people believed that networks are more important than education, many people put their own career success down to talent, rather than background. 41% of the people said that their parents' income had influenced their life, but at the same time, another 41% believed that they had achieved their own success.So which is more important, what you know or who you know? It seems that by working hard and making lots of connections, the answer may be that both are very important.8. Which of the following is closest in meaning to the underlined part?A. Practice makes perfect.B. Nothing is impossible.C. Hope for the best.D. No pains, no gains.9. Which of the following is NOT true according to the passage?A. 76% of the people think social relationship matters most.B. 41% of the people believe parents' income is most important.C. 76% of the people think family background ranks first.D. 41% of the people believe they gained their own success.10. From the passage we can infer that the writer writes the article to _____.A. stress the importance of educationB. challenge the traditional beliefC. make lots of social connectionsD. encourage people to work hard11. Which of the following is the best title for the passage?A. The Way to SuccessB. Keep your Dream in MindC. A Wealthy and Smooth CareerD. A Survey on People's DreamsDMost people know something about the greenhouse effect. Factories send gases such as carbon dioxide, or CO2, into the atmosphere, the air around the earth. In the past, this wasn’t a problem because trees absorbed the CO2. But now people in many countries are cutting down billions of trees all around the world. At the same time, factories are sending more CO2 into the atmosphere. It’s difficult to believe, but factories put billions of tons of CO2 into the atmosphere every year. One ton is over 2000 pounds, so it is a lot of pollution. There is too much CO2 and there aren’t enough trees, so the world is getting warmer. In other words, we have a greenhouse effect. This is terrible for the environment.What can we do about this? First, we can stop using so much coal and oil. We can learn to use different kinds of energy: the sun, wind, steam from volcanoes, and heat from inside the earth. Second, instead of cutting down trees, we should plant more trees. One tree can absorb ten pounds of carbon dioxide every year. The trees are good for the earth’s atmosphere and for Guatemala(拉丁美洲国家危地马拉). In small towns and villages in Guatemala, most women are poor and have hard lives. Trees help them in three ways. First, the Connecticut factories pay them to plant the trees. Their pay is corn, not money. The corn is good for their children. Second, these women know a lot about their environment. They know where to plant, when to plant, and what kinds of trees to plant. For example, they plant many fruit trees. The fruit gives them vitamins for their families’ diets. Other trees are good for firewood. In a few years, the women won't spend so much time looking for firewood. Third, all these trees are good for the soil. Now rain can’t wash the soil down from the mountains so easily.This plan isn’t enough to stop the greenhouse effect. However, it’s a start.The woman of Guatemala are helping themselves and helping their environment.12. Which of the following statement is NOT true?A. Factories send more CO2 into the atmosphere.B. Trees can’t absorb the same CO2 as they did in the past.C. Billions of trees are being cut down throughout the world.D. The greenhouse effect is extremely bad for the environment.13. What’s the main idea of the second paragraph?A. The reasons why we should plant more trees.B. Ways we can adopt to take heat from volcanoes.C. Measures to be taken to forbid the use of coal and oil.D. Things we can do to stop or reduce the greenhouse effect.14. How does planting trees help improve women’s lives in Guatemala?A. By preventing the greenhouse effect.B. By developing their skills of planting trees.C. By enabling them to earn more money to support their family.D. By making them get corn and fruit to feed their family in return.15. What’s the author’s attitude towards the plan of p lanting trees in Guatemala?A. Critical.B. Neutral.C. Positive.D. Doubtful.第二节(共5小题,每题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。

She quickly lowered the fire and turned toward a phone camera as hundreds of people watched her online. "It ruins the dish if you burn the breadcrumbs,” She advised her live-stream video watchers.Many people in China are restricted to their homes in the effort to stop the spread of coronavirus. Millions of them are finding a new interest in cooking. People watching television and online cooking shows are learning how to make Chinese and Western foods. They are also pushing up the sale of special cookware on online markets, because cooking tools matter tosome recipes. Downloads of the top five recipe apps doubled in February, said research company Sensor Tower, i.e. more than 2 million downloads. The Chinese video streaming company Billibilli said it has had more than 580 million views of its cooking videos in the two months since the coronavirus began to spread in China.Another online cooking show producer DayDayCook told reporters its number of new users increased 200 percent from January to February. A recipe for bean curd and shrimp received the most views. "We have never gained new users with such speed since we launched the service in 2012," said founder and leader Tan Xiaoyong.Many new home cooks are young people living in cities, say industry leaders. This group is used to eating in restaurants or getting food delivery. Now these people are cooking at home.Huang Yifeng, is a 28-year-old who works in Beijing, the capital. She was among those trapped at home in February. She says she spent a lot of time online, learning how to make bread and other foods.

In addition, the low-carbon diets may also improve levels of HDL cholesterol(胆固醇), although it’s not clear how much difference this would make to your overall health.The search for a diet that helps people lose weight goes back decades. In recent years, there’s been much discussion about the strong points of low-fat diets, compared with low-carbon diets. And some claim that the low-carbon diets work well for short-term weight loss, but there isn’t enough evidence to show how well the two types of diets work and what the effects are on people’s health in the long term.In addition, it’s been recognized that weight-loss programs are better if they include some support to help people make changes to their eating and exercise habits. This is often called behavioral therapy, because it works through changing peopl e’s behavior. The new study has researched people who followed a weight-loss program over two years, all of whom had behavioral therapy. According to the actual situation of different people, half the people followed a low-carbon diet, and half followed a low-fat diet. And the result shows:people on both diets did equally well in losing weight. After two years, they had lost on average7 kilograms. This amount of weight loss is enough to have positive effects on the health of fat people. What’s more, t he group who had the low-carbon diets had much better levels of HDL cholesterol than people on the low-fat diets.If you need to lose weight, this study shows that the behavioral therapy is able to work effectively. You may find it easier to lose weight as part of a supervised weight-loss program that can help you break bad habits and make healthy changes to your diets and lifestyle.28.

Between 1961 and 2016, the average annual increase in global food fish consumption outpaced population growth. Those are figures not sustainable for us, the fish or the environment as a whole.Cellular seafood could be the answer. Just don't make the mistake of calling it lab-grown fish. “None of us in the industry would call it lab-grown seafood,” says Mike Selden, CEO of Finless Foods. “Finless Foods isn’t lab-grown. We experiment and create our science in the lab, but d on’t produce there. Our products come from a production base much like a farm as a production base for animals.”Finless Foods is a tech company in San Francisco. Beginning in 2017, it’s been working to bring to market a species of cultured bluefin tuna (蓝鳍金枪鱼)created using cellular technology. Shortly after that, the company produced its first pound of bluefin tuna meat for a cost of about $19,000. Since then, however, it’s been working to bring that price down.Selden terms what Finless Foods is do ing as “cell-based seafood”. “We’re growing seafood from real seafood cells,” Selden explained. “We take cells from a fish once, and then grow them endlessly from that. We do the same process that happens inside of a fish and make it happen outside of a fi sh.”The goal of cellular seafood isn’t to entirely destroy the current seafood industry. Instead, it’s intended to augment it—and perhaps to help reduce some of the more harmful aspects of current fishing practices like overfishing and illegal fishing. And when it comes to certain sea species, this laboratory-based approach could help create a plentiful supply of certain fishwithout endangering the survival of certain overfished species as a whole.32.
