阅读下列短文,从每题所给的四个选项(A、B、C和D中选出最佳选项)

A

London―Big Ben, the landmark London clock renowned for its accuracy and chime(钟声), stopped ticking for 90 minutes, an engineer said Saturday.

Officials do not know why the 147-year-old clock on the banks of the River Thames stopped at 10:07 pm on Friday. It resumed keeping time, but stalled again at 10:20 pm and remained still for about 90 minutes before starting up again, a spokeswoman for the House of Commons said.

There has been speculation(推测) that a recent period of hot weather may have been to blame. Temperatures in London reached 90ㄈ on Saturday, and forecasts called it England’s hottest day in May since 1953.

Big Ben, which is operated by the Palace of West-minister, survived attacks by German Luftwaffe bombers during World War Two, continuing to mark the time to within 1.5 seconds of Greenwich Mean Time.

However, the clock has experienced occasional problems. In 1962, snow caused the clock to ring in the New Year 10 minutes late. In 1976, the clock stopped on April 30, 1997, and once more three weeks later.

Big Ben is actually the clock’s 13-ton bell, which was named after Sir Benjamin Hall, the British commissioner of works at the time the clock was built.

The official name for the Gothic tower holding Big Ben is St. Stephen’s Tower. Standing 315 feet tall, it was completed in 1858 after an 1834 fire destroyed most of the Palace of Westminister.

56. What does the underlined word “resumed’ (in paragraph 2) mean?

 A. stopped something from happening      B. Went on doing something

 C. stopped because there is not enough power to keep it going

 D. started doing something again after stopping

57. How many occasional problems has Big Ben experienced so far?

 A. 3.            B. 4.            C. 5.              D. 6.

57. Which of the following statements is TRUE according to the passage?

 A. Big Ben was known only for its accuracy.

 B. Big Ben also stopped because of the hot weather on April 30, 1997.

 C. German Luftwaffe bombers didn’t destroy Big Ben during World War Two.

 D. An 1834 fire destroyed most of the Palace of Westminister including Big Ben.

58. Which is the best title for the passage?

 A. Hot weather is to blame

What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you well in at school. On the other hand, you may not have any specially satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools, perhaps you are a poor speller or can’t add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

60. What is the passage mainly about?

 A. The significance of working hard at school.

 B. The direct and indirect value of school work.

 C. How to face one’s weakness.

 A. can help afford one’s education

 B. is a good way to practice skills learnt in school

 C. can help you to prepare for future work

 D. is a waste of time that could have been spent on study

62. From the passage we learn that if a student’s school performance is not good, he _______.

 A. should pay more attention to learning skills and developing abilities

 B. will be regretful about his bad results

 C. may also do well in his future work

   Happiness, rather than working hard, is the key to success, according to research published yesterday. Cheerfu1 peop1e are more 1ikely to try new things and challenge(挑战) themselves, which strengthens their good emotion and leads to success in work,good relationships and strong health,say psychologists(心理学家).

   The findings suggest that happiness is not a “ feel-good” luxury(奢侈品),but is necessary for people’s well-being. What is more, happiness can also reach an entire nation,with people in” happy” nations being more likely to help others.

 

 The link between happiness and success was studied by a team from the University of California Riverside,led by Professor Sonja Lyubomirsky.

   First, they examined questionnaires that ask peop1e about their 1ives. “ For example, they show that happy people are likely to earn higher incomes” said Lyubomirsky. Having established the link,they wanted to discover the cause.

   “Almost always it has been taken for granted that things that connect closely to happiness are the causes of happiness,but it could be just the opposite that those things are likely to be caused by happiness,” said Professor Ed Diener from the University of Illinois,another author on the paper.

   “ There was strong evidence that happiness leads people to be more sociable,more generous and more productive at work,to make more money,and to have stronger immune(免疫)systems,”said Lyubomirsky.

   The research shows that while success can put a spring in someone’s step,peop1e need happiness in the first place to achieve success.

   According to the study, around 4 out of 5 people in modern industrialized nations arc happy at any one time.

   Success was not just about earning lots of money. “ We describe success as having the things that culture or society values,whether it be friends,close family, money and income,or long life,”said Diener.

    However,sorrowful people arc not predetermined to lead a life of failure.

64. In this passage,which of the following viewpoints does Professor Lyubomirsky state?

  A. People in less happy countries are more likely to help others.

  B. Things connected to happiness are brought about by happiness.

  C. Happiness results in richer and healthier people.

  D. Success means possessing things that a cu1ture or society thinks highly of.

65. The underlined phrase “ put a spring in someone’s step” means          .

  A. put you in good spirits            B. put spring water on your feet

  C. have a pleasant walk in spring      D. step into a cheerful spring

66. According to the passage,which of the following is true?

  A. People arc happy because they earn more money.

  B. People earn more money because they are happy.

  C. Working hard is important for being successful.

  D. We can do whatever we like as 1ong as we feel happy.

67. We can infer from the passage that          .

  A. fee1ing good is a cause and not an effect of achievement

  B. our life would be a failure if we were not happy

  C. happiness is just a personal problem

D

  

For some scientists, every day is Groundhog Day. But these researchers aren’t looking for a shadow. They’re trying to figure out how groundhogs each year put themselves into a state of nearly being dead. Body temperature quickly goes down, metabolism(新陈代谢) nearly shuts down, and heart rate slows to something nearly dead. Something changes these normally warm-blooded animals into cool balls.

  But what? The answers could have deep implications(暗示) for humans . Explaining the mystery of hibernation(冬眠) is necessary for the attractive deep-space travel. If future generations are to stand an interplanetary journey(星际旅行), researchers must learn how to use animal-like hibernation . More immediately ,scientists believe the secrets of hibernation could drive great advances  in stroke(中风) treatment, injury survival and even weight control.

  “Why is it that this animal can eat like persons who are fat for several months and then shut off for a number of months?” asked Gregory Florant. He studies groundhogs, trying to understand how their energy regulation can change so greatly.

  Contrary to popular ideas, hibernating animals don’t sleep for the winter and wake up in the spring. Hibernation is not sleep. An animal will periodically wake and then go back down into a state known as torpor(蛰伏). The particular mark of hibernation is a great rise and fall in metabolism ?wild swings (突然转变) in body temperature and blood flow that a person could not stand..

  Since so many different mammals can hibernate, scientists believe the ability for human to survive similar changes of metabolism is probably buried in the genetic code, which remains a mystery. “ We are mammals, therefore we share genes with other mammals that can do this ,” Dr. Florant said. “We haven’t discovered what genes are directly involved.”

  But researchers have recently gained some important breakthroughs about the process.

68. According to the passage, “groundhogs” should be ________ .

A. a kind of bird                    B. cold-blooded animals 

C. animals able to hibernate         D. a kind of snake                                               

69.According to the passage ,when groundhogs are hibernating, they ______ .

  A. will experience great energy regulation changes

  B. can still fly freely together

  C. must change some genes in their bodies

  D. will completely shut down their metabolism

70. Finding out the secrets of hibernation is important for interplanetary journey

 

because travelers probably _______ .

  A. can change their body temperature            B. can control their blood flow

C. can stand temperature changes in space       D. don’t need to carry much food

71. Which of the following would follow the last paragraph?

  A. The environment for hibernating animals   B. The recent discovery about hibernation

  C. The process of hibernating              D. The recent discovery of space travel

Seeing may be believing,but hearing a sound first may help your sense of sight,according to results of a new study.

   Researchers at the University of California of San Diego report that people were more accurate at noticing a flash of light when a sound was produced at the same place immediately before the light flashed.

   “We used a loud sound to catch our participants’(受试者)attention” one of the study’s authors, Dr McDonald, said in an article.  During some experiments, the sound occurred at the same location as the flash of light,while at other times it was produced on the opposite side of participants’ field of sight. The 33 participants in the study were more accurate at noticing the flash of light when the sound occurred on the same side,suggesting that sound can help direct visual(视觉的)attention.

   According to McDonald, his research team plans to continue studying the relationship between sight and sound. It will be interesting to see, he said,what happens to the ability to pay attention when one of the sense does not work as well as it should,as in a person who is blind of has hearing problems.

   McDonald also noted that research into the relationship between sight and sound could affect the way we 1ook at peop1e with attention disorder. Traditionally,these people together are considered to have attention prob1em,but in some people the problem may be caused by hearing or sight deficits(缺陷).

   “ It could be possible that they cou1d have a deficit in one sense or another,or in relating sight and sound together,” McDonald said. Research into this area may lead to better treatment for people who have a hard time paying attention. It may be a good idea to take into consideration the relationship between sound and sight when designing warning signals,such as for an airplane pilot.

72. By saying “ Seeing may be believing” ,the writer is suggesting that          .

   A. there is a relationship between hearing and seeing

   B. the saying has some influence on their research

   C. you should read the research findings in this article

   D. you should visit the laboratory in person

73. One question the research team wants to study is how           .

   A. to deal with people’s hearing problems

   B. to improve pilots’ attention during flight

   C. people with hearing or sight deficits can improve their attention

   D. hearing or sight deficits affect people’s ability to pay attention

74. McDonald believes that the study of the relationship between sight and sound will        .

   A. have practical values for medical doctors and pilots

   B. help change the well-being of medical doctors

   C. prevent people from having hearing or sight problem

   D. help to improve people’s eyesight

75. Which is the best title for the passage?

   A. A cure for people with hearing problems.

   B. The study of people’s attention.

   C Sound helps to improves people’s attention.

   D. Sound helps to notice the flash of light.

Bhopal chemical leak, December 1984, Bhopal, India

An explosion in the Union Carbide chemical plant in Bhopal, India, released a deadly gas called methyl isocyanate, which is used to make pesticides. The gas formed a cloud that killed 2,500 people; another 50,100, 000 people became ill. Trees and plants and plants in the area became yellow and brittle. The explosion was caused by a mechanical failure that was not noticed in time to stop it.

Exxon Valdez oil spill, March 1989, Alaska, U.S.

On March 24,1989,11 million gallons of crude oil spilled into prince William Sound from the tanker Exxon Valldez when its hull hit a reef and tore open. The oil, which is not yet cleaned up after billions of dollars have been spent and the millions of birds, fish, and other wildlife have died, was caused by human error and could have been avoided.

Chernobyl, April 1986,USSR

At 1:23 A. M. on Saturday, April 26,1986m the reactor blew at the nuclear power plant in Chernobyl, ripping open the core, blowing the roof off the building, starting more than 30 fires, and allowing radioactive material to leak into the air. Some 31 people were killed and 200 people were treated for radiation poisoning. Still at risk are 135,000people from the 179 villages within20 miles of the plant who were exposed to the radiation before being evacuated. Glaring violations of safety rules were at the bottom of this tragic event.

Love Canal, 1953,New York, U.S.

Love Canal, a small town in upstate New York near Niagara Falls, was destroyed by waste from chemical plants. Beginning in 1947, Chemical companies could legally dump their waste products into the canal. The area developed a foul smell, trees lost their bark, and leaves fell throughout the year. A health survey found that the drinking water contained excessive levels of 82 industrial chemicals, 7 of which were thought to cause cancer. The people of Love Canal had an unusually high rate of cancer and birth defects. Eventually, many of the houses had to be abandoned. Today, the town has be partly cleaned up and some families have moved back to area.

One possible version:

It is a custom for all members of each family, married and unmarried, to gather at their parents' house to celebrate the Chinese New Year. Adults in the family all work together to make a special kind of Chinese foodjiaozi, while small children play about in the house, or watch the Spring Festival Eve Variety Show on TV. When the New Year bell sounds, fireworks and crackers begin to explode here and there, which usually lasts for hours. Then a special meal of jiaozi starts and the whole family stay up for the night, chatting and playing games.

During the next few days, quite a lot of people visit Chinese temple fairs, which are quite like carnivals in the West. Some families go to places of interest for a visit throughout the country.
