ADear daughters,Most parents tell their children, “You can be anything you want when you grow up.” I feel the same and I say this often. But I also want you to understand that realizing your dreams comes from hard work, some good luck and good timing.Here are some words of wisdom for you as you make your way in the world, from an entrepreneur (企业家) and from your mama.1. Be open-minded to changing your path along the wayIn high school, I wanted to be a politician. I left my hometown and went off to college in Washington,DC. There, I discovered that I loved to support women. It taught me that I’m creative, a strong leader and great at marketing. As a result, I moved on to be the head of a national health-care nonprofit. Becoming a mother while in that job opened my mind to launching a breast pump bag (储奶袋) business. Now I run a highly successful company that I started up on my own. I'm not a politician!2. Failure is critical to your successFailure can be heartbreaking. But I will tell you that every failure I’ve had along the way has absolutely made me better.Failing the big math exam in high school and going to summer school was embarrassing. I eventually passed, and I’ve never failed an exam again. I learned from that experience to ask for help. Now, I ask for help in business all the time.I’m proud to be a role model to you as a mom and an entrepreneur. I hope I inspire you to believe that you can be anything you want. It will be my pleasure to watch your lives unfold before my eyes.Love,Your mom21. In the writer’s opinion, what does it take to realize one’s dream?A. Failure, hard work and good timing.B. An open mind, failure and hard work.C. Hard work, good luck and good timing.D. A good dream, an open mind and hard work.22. What did the writer learn from her failure?A. Failure can make us embarrassed.B. We shouldn’t get angry when we fail.C. Don’t care too much about your failure.D. It’s important to turn to others for help.23. Which of the following words best describe the writer?A. political and proud.B. caring and cautious.C. modest and unlucky.D. flexible and successful.BLarge ecosystems（生态系统）, such as the Amazon rainforest, will collapse and disappear alarmingly quickly, once a crucial tipping point is reached, according to calculations based on real-world data.Writing in Nature Communications, researchers from Bangor University, Southampton University and the University of London, reveal the speed at which ecosystems of different sizes will disappear, once they have reached a point beyond which they collapse — transforming into an alternative ecosystem. For example, once the “point of no return” is reached, the Amazon rainforest could shift to a savannah-type ecosystem with a mix of trees and grass within 50 years, according to the research. Some scientists argue that many ecosystems are currently teetering（摇晃）on the edge of a cliff, with the fires and destruction of both the Amazon and Australian rainforests.“Unfortunately, what our paper reveals is that humanity needs to prepare for changes far sooner than expected,” says joint lead author Dr Simon Willcock of Bangor University. “These rapid changes to the world’s largest and most typical ecosystems would impact the benefits which they provide us with, including everything from food and materials, to the oxygen and water we need for life.”Ecosystems made up of a number of interacting species, rather than those dominated by one single species, may be more stable and take longer to shift to alternative ecosystem states. “Theseexample, elephants are termed a “key stone” species as they have a disproportionately（不成比例地）large impact on the landscape —pushing over trees, but also dispersing seeds over large distances. The authors state that the loss of key stone species, such as this, would lead to a rapid and dramatic change in the landscape within our lifetime. “This is yet another strong argument to avoid degrading our planet’s ecosystems; we need to do more to conserve biodiversity,” says Dr Gregory Cooper, University of London.24. What is the phenomenon described in paragraph 2?A. Many ecosystems are in danger currently.B. Large ecosystems have reached a tipping point.C. A new ecosystem will appear in the Amazon forest.D. Ecosystems are changed mainly due to natural disasters.25. What is paragraph 3 mainly about?A. The benefits of large ecosystems.B. The ways to prepare for the changes.C. The introduction to typical ecosystems.D. The influences of ecosystems’ changes on humanity.26. Which of the following best explains “mitigate” in the last paragraph?A. cause.B. ease.C. increase.D. judge.27. Why does the author mention elephants in the passage?A. To prove the destructive power of elephants.B. To explain the reason for the reducing grassland.C. To present the great influences of large animals.D. To stress the importance of conserving biodiversity.CAlthough Paris is often considered the city of romance, close to a million adults who call it home are single. Many single people say that France’s capital is one of the most difficult places to meet people. The complaints of this lonely group have inspired a new phenomenon known as “supermarket dating”. At Galerie Lafayette Gourmet, singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes，brown hair, and is 1.8 meters tall, or whatever may be on their romantic shopping list.At this Paris location, single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door, they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly, and then they have to wait in line for their turn to wander the store aisles. With purple baskets in hand, shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay, they can go to the checkout line for singles who want to chat.Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish (美化) one’s appearance or to lie about one’s age over the Internet. The supermarket, on the other hand, is considered a safe and casual environment in which to meet a potential match. In addition, what one finds in another’s grocery basket can say a thing or two about that person’s character or intentions. Buying pet food can be a man’s way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These days it’s possible to find much more than food at a grocery store.28. What do many single people in Pairs complain about?A. The difficulty in finding a match.B. The idea of supermarket dating.C. The items on their grocery list.D. The inconvenience in shopping.29. Which of the following can be inferred but is not clearly stated in the second paragraph?A. The dating supermarket is located in Paris.B. The dating supermarket is open only on Thursday evenings.C. Only single people can shop in the supermarket.D. The dating supermarket has very good business.30. How do love shoppers meet one another?A. They schedule their meeting in advance.B. They go through a special checkout.C. They pick out their groceries with great care.D. They dial the phone numbers on their shopping items.31. Why do the people prefer the supermarket dating to Internet dating?A. The supermarket dating is more convenient.B. The supermarket dating is more fun.C. The supermarket dating is more trustworthy.D. The supermarket dating is more economical.DAny time we burn fossil fuels, we’re pumping fine particulate matter（细颗粒物）from oil, gas and other toxins（毒素）into the air. “Some of these carbon particles can persist in the lungs for decades,” says Dr. Don Sin, a respirologist and director of the Centre for Heart Lung Innovation in Vancouver.Over 7,000 Canadians died from complications due to poor air quality in 2015. A study in the European Heart Journal earlier this year found that air pollution now kills 8.8 million people worldwide per year — more than tobacco smoking.Sin adds that women’s lungs seem particula rly easy to get cancer from pollution. Currently, 10,000 Canadian women die of lung cancer every year, and 15 per cent of new cases are people who have never smoked. “In Canada, lung-cancer deaths in female non-smokers will very soon probably outnumber the deaths from breast cancer, because lung cancer is so deadly,” he says.Contributing to air pollution are the 8,000 wildfires we experience every year in Canada, like those that destroyed large areas of Alberta this past spring. These are increasing in frequency and intensity with our hotter, drier spells. A study in the Canadian Journal of Emergency Medicine found that prescriptions for an asthma and COPD drug rose by 22 per cent in the Yellowknife region in the summer of 2014, when it was surrounded by wildfire smoke. The number of ER visits for breathing problems was 42 per cent higher; for children, it more than doubled.Another threat to breathing is mould, which is a concern in areas with repeated flooding, such as around New Brunswick’s Saint John River, where flood waters have been in homes for two years in a row and displaced more than 200 families. Moulds produce toxins and spores that can trigger allergic reactions or infections if taken in. Rising sea levels and increased urban development, combined with intense rainfalls, mean we will see a lot more of it.To avoid breathing polluted air, wear a mask rated N95 —not a surgical mask, which is useless, says Sin. “Those are too thin and easily torn. They won’t protect you at all from air particles.” On bad-air days, get your exercise indoors, for instance by walking in an air-conditioned mall.32. Which of the following is True according to the passage?A. 15 per cent of Canadian women have never smoked.B. 1,000 Canadian women die of lung cancer every year.C. Air pollution has killed 8.8 million people in the world.D. Over 7,000 Canadians died as a result of air pollution in 2015.33.
