Her parents had bought a house on a large plot of land near a gateway to Yosemite National Park. Benjamin could stay with them while she worked at a supermarket in town. He could run around in the hills. What she hadn’t quite accounted for, though, is how the hills are becoming hotter, drier and more dangerous.A year after they moved came the first of an annual series of wildfires, and an asthma diagnosis (哮喘诊断) for Benjamin. One year, they had to leave from their home for a few days. Another year, they bought air-conditioners so they could keep the windows shut when the air got thick an d smoky. This year, just as it seemed like Benjamin’s asthma was relieving, came the Creek Fire in the hills nearby. The air turned white with smoke. The boy had what appeared to be a mild asthma attack.Ms. Blake struggles to explain to him why he can’t be outside exploring. She worries when he goes to school. She wonders how much longer the family will be able to insure their home if rates climb higher —and what they’ll do if insurance becomes unavailable at any price. “It seems every year there’s some major fire,” Ms. Blake said. “We’re smoked out. It’s hard to breathe. It’s always a worry that you’re going to have to flee or you’re going to lose your home.” She said she had spent in the neighborhood of $1,000 this year to equip her home. “To protect my son of course I’m going to do that,” she said. “But it’s fundamentally unfair.”4. What can be learned from paragraph 1 and paragraph2?A. Benjamin likes living in San Francisco Bay AreaB. Benjamin didn’t have an asthma before moving.C. Ms. Blake stayed with her son while working.D. Ms. Blake could explain how the hills are becoming drier.5. Why did Ms. Blake buy air-conditioners?A. To help cure Benjamin’s asthma.B. To keep the air cool in hot summer.C. To keep the air drier in the house.D. To keep the windows shut when necessary.6. What is the direct factor to Benjamin’s asthma?A. Some dry brush and dead trees caused fire.B. Series of wildfires attacked his living area.C. The weather became hotter and drier.D. The air got thick and smoky in the San Francisco Bay Area.7. How did Ms. Blake feel about the series of wildfires?A. Anxious and angry.B. Concerned and confused.C. Unconcerned and uninterested.D. Positive and hopeful.CNext time you go on holiday, it’s going to feel pretty different. You may have to wear aface mask. And that means getting your point across in an unfamiliar language — all while keeping your mouth covered — could become a bit of a problem.That’s where the C-mask, by Japanese company Do nut Robotics, comes in. It’s a smart, Internet-connected mouth covering that can make calls, raise the wearer’s voice, and most helpfully for travelers, translate conversations into eight different languages.You simply place it over a standard face mask and connect it via Bluetooth to a smart phone. A special app will then allow you to record live conversations, turn them into text and translate them into English, Chinese, French, Korean, Thai, Indonesian, Spanish or Vietnamese (currently only from Japanese) — making it easy to understand what people are saying. It won’t actually speak the translated phrases for you, but it does have a built-in amplifier (扩音器) to help you make yourself heard.“We worked hard for years to develop a robot and we have used what we’ve researched to create a product that responds to how COVID-19 has reshaped society,” Donut’s CEO recently told reporters. The firm has already raised more than 28 million yen via crowdfunding to develop the product, which will go on sale for 3,980 yen in Japan.There are all manner of fashionable, eco-friendly masks you can now get your hands on —check out these in London, Singapore and Barcelona. But in creating an affordable, high-tech mask, Donut could well be on to something.8. The C-mask is developed to ________ .A. seek fashionB. reshape societyC. replace cellphonesD. promote communication9. What’s the main idea of Paragraph 3?A. How the C-mask speaks.B. How the C-mask works.C. What advantages the C-mask brings.D. What languages the C-mask translates.10. What does the underlined phrase “be on to something” in the last paragraph mean?A. take a lookB. earn a livingC. make a differenceD. issue a warning11. In which column of a website do we probably read this text?A. Health.B. Tourism.C. Fashion.D. Technology.D“The pile of ice is so thick; it extends more than 10,000 feet above the ocean. And if all that ice were to melt and go into the ocean, global sea levels would rise by about 24 feet everywhere around the world.” said Jason Briner, a geologist who studies the ice sheet in Greenland at the University of Buffalo. The ice sheet of the biggest island in the world is melting, and the ice sheet that sits atop it is massive. The ice sheet is melting, of course. But just how much, compared to the past?Briner’s team did a computer simulation (模拟) of the southwest part of the Greenland ice sheet — which he says is a good indicator for ice melting across the entire ice sheet. The researchers plugged past climate data into that model to “hindcast,” rather than forecast, thepast activity of the ice sheet. They then checked the model’s predictions of the past shape and size of the ice sheet by looking at piles of rocks and dirt on Greenland today, which outline the edges of ancient ice. And the simulation was in good agreement with the actual situation.Using that reconstruction of the ice sheet over time, the team could compare the ice sheet’s historic losses to those happening today under human-caused global warming. And they determined that Greenland is on track to lose more ice this century than during any century in the past 12,000 years — possibly four times as much.Finally, it’s up to us how much ice actually melts. If the world goes net carbon zero by 2100, for example, Briner says ice loss could stop entirely at the end of the century, according to one model. “That was what kept me from being completely depressed about our study.”Dozens of countries have already announced goals to go net zero by the middle of this century — so far the U.S. is not one of them.12. What do we know about the Greenland ice sheet?A. It is as thick as over 10,000 feet.B. It is becoming smaller and smaller.C. It has raised sea levels by 24 feet.D. It is the largest ice sheet in the world.13. How did Briner’s team conduct their research?A. By modeling part of the ice sheet on computer.B. By doing a simulation of the whole ice sheet.C. By studying the ancient rocks and dirt.D. By forecasting the future climate change.14. What can we infer about the Greenland ice sheet in the last paragraph?A. Its status has already been acknowledged.B. Its growth can be improved by the model.C. The speed of its melting will be increasingly fast.D. The extent of its loss depends on human activities.15. What is the best title for the text?A. Rising Global Sea LevelsB. Climate Change is Speeding UpC. Greenland — the Biggest Island is MeltingD. Net Carbon Zero — a Global Goal by 2100第二节(共5小题;每小题2.5分,满分12.5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。

成都石室中学高2017届高三周考(三)(满分120分)本试卷分第I卷(选择题)和第II卷(非选择题)两部分第二部分阅读理解(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的四个选项(A, B, C, D)中,选出最佳选项,并在答题卡上将该项涂黑。

AIn China, chain restaurants, especially the big multinational ones, are cool. Going to Starbucks, for example, is a status symbol. It not only says, “I‟m rich enough to buy this overpriced coffee,” but also, “I‟m cosmopolitan(见多识广的)enough to be part of globalization.”Where I come from in the UK, however, chains are neither fashionable nor gourmet(美食的). Chains are where you go on New Year‟s Day when nowhere else is open, or when you are 5 years old and your parents can‟t stand hearing, “I‟m huuuuuungry!” any longer. In my own case (with regards t o McDonald‟s), a chain is where you are taken on your first “date”. Even at the age of 13, I knew to give the guy the “let‟s just be friends” phone call the next day.In the UK, independent cafes and restaurants are making a comeback on the fashion scene. Nowadays, a Londoner who says “let‟s meet for a coffee at Monmouth” (an independent cafe) is much cooler than one who says “let‟s go to Starbucks”. Even if Monmouth‟s coffee is a little more expensive, there‟s a satisfaction in knowing your pounds aren‟t g oing straight to the big corporations.Of course, there are chain stores all over the UK; you can‟t go five minutes without spotting a Costa Coffee. But numbers do not add up to good taste.I do, however, have a confession (坦白). After moving to China I had moments when all the rice and Kung Pao Chicken became too much. I, too, have retreated to McDonald‟s.1. Many Chinese people like to go to multinational chain restaurants because ______.A. the restaurants give customers a taste of foreign culture.B. the restaurants offer different food and drinks from other restaurants.C. they believe that eating there will show their wealth and social status.D. these restaurants are perfect places for a romantic date.2. Which of the following statements is TRUE?A. The author has grown tired of Chinese food.B. Branches of Monmouth‟s cafe can be found all over the UK.C. Most independent stores are closed on New Year‟s Day in the UK.D. It is cool in the UK to take your first date to a chain restaurant.3.We can infer from the article that ______.A. the author doesn‟t like food from Pizza Hut.B. some Britons don‟t like big corporations.C. many Britons think that numbers mean poor quality.D. the author doesn‟t like to follow fashion trends.4.What does the underlined word (in the last paragraph) mean?A. adaptedB. contributedC. subscribedD. switchedBIt never occurred to anybody, not even the creators that the world would care about the complex lives, loves and sufferings o f a group of attractive and witty New Yorkers. But there‟s no doubt that Friends(老友记)has become more than just a successful situation comedy ─ it has established itself as one of the last great television phenomena of the last century. Along the way, it has made its half-dozen leading actors famous.Looking back on the strong friendship between the group of three men and three women who frequently gather at each other‟s apartments and at Greenwich Village‟s Central Perk coffee house, Friends was created by television producers, David Crane and Marta Kauffman. In 1993, the pair met producer Kevin S. Bright. Then the three became partners and got a deal to produce a new comedy for Warner Brothers. What they came up with was based on Crane and Kauffman‟s after-college years, when they hung out at the local coffee house and involved themselves in every aspect of each other‟s lives.It didn‟t take long for viewers to make friends with Friends. The situation comedy quickly became a top ten hit. Critics loved it as well. Entertainment Weekly said the show operated like a Broadway show, with twisty plots and unique jokes. The television theme song has also been a success with the public. The song‟s success helped save the television theme song. An ABC(美国广播公司)executive was ready to order very short music intros(前奏) on his network‟s shows, thinking that viewers would hit the remote control as soon as the opening started. But the success of the Friends theme song led the ABC executive to change his mind ─ remote controls or not, the TV theme song would stay.Years have gone by, but Friends remains and will remain an example of a modern US situation comedy that is both hugely entertaining television and nothing short of a genuine latter-day social phenomenon.5.What is stressed in the second paragraph?A. The origin of FriendsB. The role models of FriendsC. The popularity of FriendsD. The brilliance of Friends6.Which of the following is TRUE about Friends?A. It has a simple but entertaining plot.B. It is about friendship between college students.C. It was criticized by Entertainment Weekly.D. It first came into being in the 1990s.7.What can we learn from the passage?A. Producer, Kevin S. Bright, graduated from the same college as David Crane.B. ABC once replaced the theme song of its TV show with a short music intro.C. The ABC executive thought highly of the theme song of Friends.D. Marta Kauffman expected Friends to achieve great success.8.What might the author think of Friends?A. Its merits outweigh its shortcomings.B. He/she shows great affection towards it.C. He/she has a reserved attitude towards its success.D. Its success lies in the lack of good situation comedies.CIf a woman has an extra piece of cake,don ‟t blame it on greed, blame it on her brain.Scientists have found that women's brains react to food very differently 一and much more strongly 一than men' s. Academics found that decades of dieting pressure on women and advertising have programmed certain parts of the female brain to react strongly when faced with any kind of food. Men,on the other hand, are not usually as obsessive (着迷的)about what they eat.Dr. Rudolf Uher and his colleagues at the Institute of Psychiatry in King's College London used brain scanning technology,known as functional magnetic resonance imaging ( FMRI),to look at the brains of eighteen men and women.The volunteers were given images of food to look at, as well as food to taste. Their brain reactions were observed by the scientists.They found that the female brains reacted much more strongly than those of males.The same reaction did not happen when they were shown non-food images. The team believe this means women think more about food than men tend to.Dr. Uher said, “This could be related to biological differences between men and women. But the more likely explanation is that women have a more complicated reaction to food because of social pressure. "Professor Carey Cooper,psychology and health professor at Lancaster University,said,for centuries women have had a providing role 一preparing and cooking food for their families. And it's part of that role to make sure the food is safe. They will therefore be much more sensitive to food than men are, and I would not be surprised if that was now built into their DNA. If the female brain react to food because it historically has developed neural (神经的)pathways to do this, then food will be the way they express their stress. Food actually,is a comfort for women.,‟But other experts have said that more research must be done before the results can be proved. American scientist Angelo del Parigi of the John B. Pierce Laboratory in New Haven, Connecticut, said Looking at an FMRI alone cannot make sure whether the stronger reaction in women is due to innate (天生的)differences or a learned process. ‟‟9.In Dr. Uher … s opinion, women react more strongly to food than men most probably because they_________A. told to do so for a long timeB. influenced by advertisementsC. forced by powerful social influencesD. born to do so due to biological reasonsA. turn to food when they feel stressedB. are stressed because of food safetyC. accept their social role from the heartD. are satisfied with preparing food for their families11. What was Angelo del Parigi‟ s attitude towards the research results?A. Surprised.B. Uninterested.C. Doubtful.D. CuriousDStudies show that you may be lied to every day anywhere from 10 to 200 times. We say, “Nice song.” “Honey, you don‟t look fat in that, no.” B ut another study showed that strangers lied three times within the first 10 minutes of meeting each other. We lie more to strangers than we lie to coworkers. Men lie eight times more about themselves than they do about other people. Women lie more to prote ct other people. If you‟re married, you‟re going to lie to your wife/ husband in one out of every 10 communications. If you‟re unmarried, that number drops to three. But look, if at some point you got lied to, it‟s because you agreed to get lied to. Truth about lying: lying‟s a cooperative act. Not all lies are harmful. Sometimes we‟re willing to get lied to for the sake of social dignity, maybe to keep a private secret.Lying is complex. It‟s woven into the fabric of our daily and business lives. We‟re de eply disturbed by the truth. We explain it, sometimes for very good reasons, other times just because we don‟t understand the gaps between ideals and realities in our lives. We‟re against lying, but secretly we‟re for it in ways that our society has practiced for centuries and centuries. It‟s as old as breathing. It‟s part of our culture and history. Think the stories from Dante, Shakespeare, the Bible, News of the World.Lying has great value to the evolution of human beings. Researchers have long known that the more intelligent the species, the more likely it is to lie. We humans like to become leaders. It starts really early. How early? Well, babies will pretend to cry, pause, wait to see who‟s coming and then go right back to crying. One-year-olds learn hiding truth. Two-year-olds bluff (虚张声势). Five-year-olds lie outright and try to control via flattery (讨好). Nine-year-olds, masters of covering up.So what do we do about lies? Well, there are steps we can take to guide our way through the bushes. Trained lie spotters (检测员) get to the truth 90% of the time. The rest of us, we‟re only 54% accurate. There are clever liars and stupid liars,but there‟re no real original liars. While lying, we all make the same mistakes, and we all use the same techniques.12. From paragraph 1 we learn that lying is very ______________.A. harmfulB. commonC. interestingD. easy13. According to the passage, a lie works when__________________ .A. the liar‟s words are sweet enoughB. it is given to a complete strangerC. we are willing to lie for the dignityD. someone gives the liar cooperation14. Lying is complex because __________________.A. it is practiced by clever onesB. it is the whole part of great cultureC. ancient stories are full of liesD. people are for it as well as against it15. What might the writer talk about in the following passage_______________A. How to become clever liars.B. How to avoid stupid lies.C. How to tell truth from lies.D. How to get through the bushes.第二节(共5小题;每小题2分,共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.Hollywood movies are regularly filled with sex and violence.
