Doing Favours Can Be Dangerous

I found out one time that doing a favour for someone could get you into a lot of trouble.I was in the eighth grade at the time, and we were having a final test.During the test, the girl sitting next to me whispered something, but I didn’t understand.So I leaned over her way and found out that she was trying to ask me if I had an extra pen.She showed me that hers was out of ink and would not write.I happened to have an extra one, so I took it out of my pocket and put it on her desk.

Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed.As soon as we were alone she began to talk to me about what it meant to grow up; she mentioned how important it was to stand on your own feet and be responsible for your own acts.For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves.She made me promise that I would think seriously about all the things she had said, and then she told me I could leave.I walked out of the room wondering why she had chosen to talk to me about all those things.

Later on, I found out that she thought I had cheated on the test.When she saw me lean over to talk to the girl next to me, it looked as though I was copying answers from the girl’s test paper.I tried to explain about the pen, but all she could say was it seemed awfully strange to her that I hadn’t mentioned anything about the pen the day she talked to me right after the test.Even though I tried to explain that I was just doing the girl a favour by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

A friend of mine named Paul received an expensive car from his brother as a Christmas present.On Christmas Eve when Paul came out of his office, a street urchin (顽童)was walking around the shining car.“Is this your car, Paul?” he asked.

Paul answered, “Yes, my brother gave it to me for Christmas.” The boy was surprised.“You mean your brother gave it to you and it cost you nothing? Boy, I wish…” He hesitated.

Of course Paul knew what he was going to wish for.He wished he had a brother like that.But what the boy said surprised Paul greatly.

When other nine-year-old kids were playing games, she was working at a petrol station.When other teens were studying or going out, she struggled to find a place to sleep on the street.But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University.And her amazing story has inspired a movie, “Homeless to Harvard: The Liz Murray Story”, shown in late April.

Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination.Liz grew up in the shadow of two drug-addicted parents.There was never enough food or warm clothes in the house.Liz was the only member of the family who had a job.Her mother had AIDS and died when Liz was just 15 years old.The effect of that loss became a turning point in her life.Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

Liz went back to school.She threw herself into her studies, never telling her teachers that she was homeless.At night, she lived on the streets.“What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being.I had only experienced a small part of the society,” she wrote in her book Breaking Night.

She admitted that she used envy to drive herself on.She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”.She finished high school in just two years and won a full scholarship to study at Harvard University.But Liz decided to leave her top university for a couple of months earlier this year in order to take care of her father, who has also developed AIDS.“I love my parents so much.They are drug addicts.But I never forget that they love me all the tim e.”

Liz wants moviegoers (影迷)to come away with the idea that changing your life is “as simple as making a decision”.

1.In which order did the following things happen to Liz?

a.Her Mum died of AIDS.

b.She worked at a petrol station.

c.She got admitted into Harvard.

d.The movie about her life was put on.

e.She had trouble finding a place to sleep.

A.b, a, e, c, d B.a, b, c, e, d C.e, d, b, a, c D.b, e, a, d, c 2.What decision did Liz make that changed her life?

A.To write Breaking Night.

B.To go to the best university.

C.To live through the difficult time.

D.To live a different life from her parents’.

3.When she wrote, “What drove me to live on … I had only experienced a small part of the society”, she meant that ________.

A.she had little experience of social life

B.she could hardly understand the society

C.she would do something for her own life

D.she needed to travel more around the world

Most people feel lonely sometimes, but it usually only lasts a few minutes or a few hours.This kind of loneliness is not serious.In fact, it is quite normal.For some people, though, loneliness can last for years.Psychologists (心理学家)are studying this phenomenon in an attempt to better understand long-term loneliness.These researchers have already identified three different types of loneliness.

The first kind of loneliness is temporary.This is the most common type.It usually disappears quickly and does not require any special attention.The second kind, situational loneliness, is a natural result of a particular situation—for example, the death of a loved one, or moving to a new place.Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.Situational loneliness is easy to understand and to predict.

The third kind of loneliness is the most severe.Unlike the second type, chronic (慢性的)loneliness usually lasts more than two years and has no specific cause.People who experience habitual loneliness have problems socializing.Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.

Many researchers agree that the loneliest people are between the ages 18 and 25, so a group of psychologists decided to study a group of college students.They found that more than 50% of the students were situationally lonely at the beginning of the term as a result of their new circumstances, but had adjusted after a few months.Thirteen percent were still lonely after seven months due to shyness and fear.They felt very uncomfortable meeting strangers, even though they understood that their fear was not reasonable.The situationally lonely students overcame their loneliness by making new friends, but the chronically lonely remained unhappy because they were afraid to do so.

Psychologists are trying to find ways to help habitually lonely people for two reasons.First of all, they are unhappy and unable to socialize.Secondly, researchers have found a connection between chronic loneliness and serious illnesses such as heart disease.While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous, condition.

1.The passage mainly talks about _______.

A.the subjects of psychology B.the study on loneliness

C.the interests of psychologists D.the treatment of loneliness

2.All of the following are true EXCEPT that _______.

A.situational loneliness can cause physical problems

B.temporary loneliness does not need special attention

C.chronic loneliness can cause problems in socializing

D.37% of the students can overcome loneliness easily

3.The underlined word “adjusted” in paragraph 4 means “________”.

A.had no trouble understanding others B.got used to the new situation

C.changed themselves slightly D.improved their health 4.Psychologists want to help the habitually lonely people because _______.

A.they are college students

B.they are sad and dangerous

C.they intend to communicate with others

D.they may have mental and physical problems

People generally use spices (香料)every day when preparing meals.Most of these spices are readily available in local supermarkets.However, in the 15th and 16th centuries, spices were as valuable as gold or diamonds.Spices are small plants or parts of plants, such as ginger, pepper, vanilla, and cinnamon, which are used to add flavor to our food.1 Such a use for spices actually goes all the way back to Roman times.The Romans used spices such as cumin and coriander to help preserve food.

The spices came to Europe from countries to the east, such as the islands in the East Indies, Sri Lanka, and India.2 Because of the long journeys involved, they were very expensive.European sailors began to look for routes to these countries themselves in order to bring back the spices by sea.In 1498, a Portuguese explorer named Vasco Da Gama reached an East Indies island called Calicut.3 In 1519, another Spanish explorer, Ferdinand Magellan, found a new trade route by sailing west across the Atlantic Ocean, around the southern tips of both South America and Africa, and back to Europe.

4 Portugal was the leader until the end of the 16th century.Spain was in control during

much of the next 100 years.Then, Holland took over.The Dutch controlled the East Indies, but, in 1780, England defeated them in a famous war.5 They treated the people there badly and made them submit to the British government.

India finally became independent from Britain in the 1940s.Today, it is still called “the land of spices”.In fact, at present India produces 2.5 million tons of spices each year and produced more types of spices than any other country.

A.For centuries, Arab traders had carried the spices over land and sold them to European countries.

B.For the next four centuries, Western countries raced each other for control of the spice trade in these new countries, which they called the “New World.”

C.Though they might not be as valuable today as gold or diamonds, spices are still big business around the globe.

D.Six years earlier, Spanish explorer Christopher Columbus had been looking for spices when he discovered America.

E.The English then moved from the islands into India.

F.The history of spice is almost as old as human civilization.

G.In those times, spices also helped keep meat from spoiling.

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. (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. 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
