A report from the United Nations said that around 60 million people across the world, with 80% of them in Asia, are drinking polluted water. Some 4,500 children die every day because of polluted water.

A report showed that environmental problems kill 3 million children under five years old each year, making them one of the key contributors in more than 10 million child deaths worldwide each year.

Dangerous factors include indoor and outdoor air pollution, water pollution, lack of good hygiene facilities and poor ecological systems，it said.

Another study showed that parents and experts from seven countries including the United States, India and Nigeria, regarded pollution as the biggest threat to children's natural living environment.

Many parents say that children today are being brought up with fewer blue skies than when they were little kids.

Mrs. Green tries to teach her daughter Su san by setting a personal example. She picks out recyclable waste and uses the water from the washing machine to wash the toilet.

Chinese children mostly learn about environmental protection in school.

Some non-governmental organizations and child centers also teach kids to protect the environment. “More pa rents have become aware of it. Family is now playing a more important role,”says a Chinese official.

Vera Lehmann, an expert from Germany says many Chinese are increasingly aware of polluted. “I was surprised to find how much schools in China are willing to contribute to educating the children on environment,” Lehmann said.“There has been a big change between now and ten years ago when I first traveled here.”

高考英语阅读理解三篇

(A ) A coal-fire stove(炉灶)provided heating for Zhao Yaoqin's courtyard bungalow in a Beijing hutong all her life. This winter, however, the stove has disappeared from the 66-year-old's life, and an electric radiator takes its place beside her bed, a product of a government to use clean energy in the national capital. With the Olympics to be staged in Beijing next August, the city is determined to eliminate the use of coal within the Third Ring Road that circles the city before the Games. The project to replace the stoves with electric radiators has been part of the effort. When the city's four-month long heating season started on Thursday, coal-fired stoves, known as a big source of pollution in the big city, have disappeared from some 20,000 local households like Zhao's bungalow in the inner city "hutong" -- traditional alleyways(小巷) that date back centuries. "We used to boil water or bake bread on the stove," said Zhao, sounding sentimental(伤感) to the disappearance of the coal furnace from her life. Late in the 1990s, Beijing's air quality monitoring office found that the emissions(排放) of sulphur dioxide and carbon monoxide from the hutong areas have been higher than the city's average in winter, mainly because of the coal stoves. With the project to switch to clean energy for heating launched in 1999, the emission level of the two poisonous substances decreased by 42 percent and 44 percent, respectively, this year from 2001 levels. Zhao said the fee for electrical heat for the entire winter was usually around 2,400 yuan (US$323) per household. With the government's subsidy（补贴）, however, she only needed to pay about 500 yuan, nearly the same price as that for coal. 1．Zhao Yaoqin’ example in the passage is to tell us that_______. A.people in Beijing using electric radiators to welcome the Olympics. B.people in Beijing are doing something to protect the environment. C.hutongs in Beijing have a long history. D.People pay more money to use electric radiators than before. 2. The underlined word eliminate probably means________ A. cut down. B. increase. C. get rid of. D. replace 3. We can infer from the passage that ______ A. Zhao Yaoqin has a strong and deep emotion with the use of coal-fire stove. B. The government will pay most of the fee. C. The air of Beijing has been badly polluted since 1990s. D. The people do not use coal eight months in one year. 4. Which of the following is NOT true according to the passage? A. The clean air is important when the Olympics Games is held in Beijing. B. The success of the Olympics Games depends on the clean air. C. The government spare no effort to make the environment better. D. The emission level of poisonous substances will be low in 2008.

One【2019届上海市虹口区高三英语一模试题】 Section B Directions:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read. (A) There aren’t many actors around the world who have enough self confidence to turn down an offer from Steven Spielberg. Maybe that was why Juliette Binoche gave him a choice. She said she’d be happy to be in Jurassic Park as long as she could play a dinosaur. Of course he turned her down and it was probably a good thing. It’s difficult to imagine Juliette ripping people apart with her teeth. However, her decision doesn’t seem to have done her career any harm. She has gone on to make a string of hits, including The Unbearable Lightness of Being, The English Patient (for which she won an Oscar) and Chocolat. Success in the United States has not been so easy for other foreign stars. Gerald Depardieu is a good example. Since his first film in 1967, his filmography(影片集锦) lists 172 acting credits. But he has struggled on the other side of the pond. While some of his films have been popular in the US, they have usually been French films that travelled. One possible exception was Green Card, directed by Peter Weir, where he plays a French immigrant who goes through a fake wedding in order to stay and work in the United States. This is a predictable but sweet romantic comedy which typecasts (分配同一类型角色) its lead actors in terms of national stereotypes. While some reviewers were kind, others shredded both the film and Depardieu’s performance. While Monsieur Depardieu has n’t received the recognition he would have liked in the United States, one Mexican actor has achieved almost instant success. Gael Garcia Bernal first gained recognition in Amores Perros in 2000 and a year later in Y tu mama tambien. Since then he has appeared with hometown hero, Brad Pitt in Babel and, under the direction of top producer and director, Jim Jarmusch, he starred in Limits of Control. He hasn’t picked up an Oscar yet, but he

(英语)高三英语阅读理解专项训练及答案

（英语）高三英语阅读理解专项训练及答案 一、高中英语阅读理解 1．阅读理解 The setting was a packed gymnasium just before the start of a game against another school. There were five girls who were members of the Danville High School basketball team—all of them starters. They were not in uniform to play that night and would not be on the team for the rest of this season. They were there to admit their breaking of team rules. They were there to support their coach's decision to take them off the team. They were there to let the town know there was a problem in their little community that needed to be addressed. And they did it with sincere regret rather than defensiveness. While the school had been out for the New Year's holiday, the five girls had gone to the party with several of their friends. There was alcohol there. And they all drank some. Coach Rainville has a zero tolerance rule on drugs and alcohol for her members though it was a hard decision to make. When classes resumed and accounts of holiday parties were shared, rumors about the five girls began closing in on them. The coach said she couldn't back down on her rules. And the players—two junior students and three senior students—agreed. That night in the gym was part of their public support of the coach's decision. “We hope you will understand that we are not bad kids. What we did was definitely not worth it. We hope this event will make everyone realize that there is a big drug and alcohol problem in our community,” one of the senior students said, “And if you work with us to try to solve this problem, you will help us feel that we have not been thrown off our basketball team for nothing.” The five left the floor to deafening applause. The team may not win another game this year. But they've learnt something about personal responsibility, the effect of one's action on others, and honesty that will serve them well throughout life. （1）It can be inferred from the passage that the five girls who were kicked off the team were ________. A. very good players on the team B. addicted to alcohol and drugs C. three junior students and two senior students D. scolded by their parents for drinking alcohol （2）What did the girls do to support their coach's decision? A. They didn't fight for Danville High School any more. B. They all gave speeches to apologize in the local press. C. They admitted their mistake in public in the gymnasium. D. They would never drink any alcohol throughout their life. （3）Which word best describes the coach Rainville? A. Indifferent. B. Strict. C. Stubborn. D. Cruel. （4）Which would be the best title for the passage? A. Growing up with pain B. A bad mistake C. Team rules are everything D. Basketball girls in high school 【答案】（1）A

I watched from a distance as the homeless man quarreled with those who did not leave money for him – the majority. I walked up to him and right on queue he asked me for a quarter. “I’ll give you a quarter if you tell me your story.” He laughed, “You’ll give me a quarter for my story?” I lay the qu front of him and corrected myself –“Nah, here’s the quarter but it would be nice to hear your story.” I followed his eyes to the quarter and for a brief moment I saw a glimmer of reflection. I sat down next to him and waited. I was a sniper(狙击手)and was supposed to shoot down the “I was in the army,” he said. “ carefully to his grizzly voice as he went deeper into the story. enemy from the distance.” I listened He wore dirty old torn clothes and smelled like a dead rat left in a mouse trap. He told me how he used to hunt with his family and was really good at it. He had his own way of respecting animals by not wasting what he killed for food and not killing more than he needed. When the army came knocking on his door, he felt pride and joined up. All those years of polishing his hunting skills could now serve a larger purpose—to defend us from the bad guys. He set out to fight in Iraq. It wasn’t long before he realized his ideals and expectations were just a shadow of the truth. He became disillusioned with the killings, which he felt were of innocent people. “I was a sniper but I never really killed anyone,” he said. “One day I had to do it. They asked me to shoot this lady from the distance. I saw kids near that lady and my hands were on the trigger (扳机). Man, I was tearing up ... I couldn’t do it. She wasn’t doing anything to anyone and she was with the kids—I couldn’t see through my tears. It just didn’t make any sense to me.” The story goes on as he describes eventually being put into prison for 180 days for refusing to follow orders.

2018届上海市各高中学校高三英语试题分类汇编--阅读理解B篇(带答案精确校对)

Section B Directions：Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read. (B) With the coming of big data age, data science is supposed to be starved for, of which the adaption can point a profound change in corporate competitiveness. Companies, both born-in the digital era and traditional world are showing off their skills in data science. Therefore, it seems to have been creating a great demand for the experts of this type. Mr Carlos Guestrin, machine learning professor from University of Washington argues that all software applications will need inbuilt intelligence within five years, making data scientists—people trained to analyze large bodies of information — key workers in this emerging “cognitive” technology economy. There are already critical applicat ions that depend on machine learning, a subfield of data science, led by recommendation programs, fraud detection system, forecasting tools and applications for predicting customer behavior. Many companies that are born digital—particularly internet companies that have a great number of real-time customer interactions to handle—are all-in when it comes to data science. Pinterest, for instance, maintains more than 100 machine learning models that could be applied to different classes of problems, and it constantly fields request from managers eager to use this resource to deal with their business problem. The most important factor weighing on many traditional companies will be the high cost of launching a serious machine-learning operation. Netflix is estimated to spend ＄150m a year on a single application and the total bills is probably four times that once all its uses of the technology are taken into account.
