asked in confidence(秘密地);they should,however,be sensible and honest ones.

During the lesson the teacher will read out a question,and then call upon one ort wo volunteers from the class to offer their opinions before giving his class should regard both questions and answers and the discussion that arises from them as confidential to avoid breaking the trust the questioner has placed in the lesson,and to make possible further discussion of similar problems on another is also helpful to remember that the answers given represent only one or two points of view—someone else might answer them quite differently.

He has fought to protect the black and white rhinoceros—targets for ruthless(无情的) hunters because their horn(角) gets high prices in Asian countries—and through the wilderness school,has taught thousands of children from South Africa and overseas about nature and conservation.

His latest project is an application to the United Nations Educational,Scientific,and Cultural Germanization(UNESCO) to have the Waterberg area in South Africa's Northern Province become a biosphere reserve(生物圈保护区).Walker believes the

future of conservation in South Africa lies in education and in private game reserves.

In 1981 Walker was point taking(定点导游) adults on wilderness that point,he decided he wanted to “do something for children”through the establishment of an environmental school.“Conita and I were prepared to look at children whose parents could afford it,and those children who came from backgrounds whose parents could never do that Conita and I set out to find a place that would be safe,sufficiently close to the main areas of Johannesburg and Pretoria,be malaria(疟病)free,have water and be benefit to education on the found this in the first year,30 children—10 of them blacks from Soweto—were present to visit the ,3,000 children a year spend time lucky enough to visit his wilderness school will see—among many species—white rhino,warthogs and red hartebeests.“What made it really bad was when I started mixing black children with white children.”When a neighbour reported Walker to the security police and at last he was asked at their notorious headquarters,Walker said“I told them that all I was trying to achieve was to give children of South Africa,regardless of their background,an understanding of conservation and awareness that our survival depends so much

on it.”

Passage 5

Former US Vice President Al Gore,who came close to winning the presidency two years ago,said he will not run in 2004,and probably will not have another opportunity to seek the White House.

Though Gore would have been a frightening Democratic(民主党的) main runner,his decision to give up the 2004 race probably helped his party's chances in the general election against President George ,Democrats said.

Many did not want to see BushGore Ⅱ.

“The last campaign was an extremely difficult one,” Gore told CBS TV show “60 Minutes”on Sunday.

While saying he still had the energy and drive to run again,Gore recognied,“There are a lot of p eople within the Democratic Party who felt exhausted(by the 2000 race)…who felt like,OK,‘I don't want to go through that again.’And I'm frankly sensitive to that feeling.”

In nearly two doen interviews after Gore announced his

plans,Democrats dutifully claimed their party had lost a top candidate,but one after another,they praised Gore for taking an early exit from a primary race he could have won,sparing them a repeat.

Gore,54,said he was making his decision“in the full understanding that it probably means that I will never have another opportunity to run for president.”

Party activists(激进主义分子)blamed Gore for losing despite a booming economy and eight years of a Democratic even lost his home state of Tennessee,a victory there would have given him the White House.

of the following can be the best title for this passage

Was Criticized Decides Not to Fight Bush in 2004

US Vice President Al Gore Gore and Gorge Bush

2. Why do you think Gore has decides not to run in 2004 according to this passage

Experts finally traced the cause of her level of

formaldehyde(甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical source of the gas Her new kitchen cabinets and wall to wall carpeting.

The Ouchidas are victims of indoor air pollution,which is not given sufficient attention partly because of the nation's drive to save problem itself isn't new.“The indoor environment was dirty long before energy conservation came along,”says Moschandreas,a pollution scientist at Geomet Technologies in Maryland.“Energy conservation has tend ed to accentuate the situation in some cases.”

The problem appears to be more troublesome in newly constructed homes rather than old in the days when energy was cheap,home builders didn't worry much about unsealed of such leaks,the air in an average home was repaced by fresh outdoor air about once an a result,the pollutants generated in most households seldom built up to dangerous levels.

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.

(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.

And the Hindus have believed for centuries that the Ganges River has the power to clean the soul, as well as the body. Several thousand years ago, the inhabitants of the island of Crete built baths with running water. The early Jews took ceremonial baths on certain occasions, making use of oils and ointments(油膏). The Jews also had a custom of bathing the feet of all strangers that came within their gates. This friendly custom is still practised in parts of Palestine. Swimming was popular among the Greeks of ancient time. By the third century before Christ, almost every Greek city of a certain size had at least one public bath. The wealthy classes had private baths and pools, some of which were beautifully decorated. Many of the public baths that the Romans built utilized natural mineral springs. Since most of these springs were naturally warm the Romans took advantage of this free hot water. By the time of the Roman Emperors, these baths were often housed in large, marble(大理石) buildings. The baths built by the Emperor Caracalla, in the center of Rome, covered about one square mile and could hold sixteen thousand people. 1 The earliest bathing place was probably_____. (A)the river (B)the Nile (C)the Ganges (D)the River Jordan 2 According to the passage, today, some parts of Palestine also have the custom of_____. (A)bathing in public baths (B)bathing for pleasure

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. He told me how he was black listed so that he couldn’t get a job. All the rights we take for granted were taken away from him. Why? Here was a man who was being punished—and for what? For refusing to kill the lady? For being a hero? “I have no regrets,”  anyone the homeless man said. “I may be homeless now, but I never killed that lady. I never killed He in the army. It didn’t feel right. I didn’t go there to do that. I went there to save people.”  okay. But I wouldn’t be able to live with continued, “I can live with being homeless—that’s killing innocent people.” On that lonely Friday night, I met a hero. It just never occurred to me that a hero could be a smelly old man left on streets. 1. It can be learned from the passage that the homeless man_______. () A. never killed animals B. had a strong respect for life C. deserved the punishment he received D. felt guilty about disobeying the order
