When I took the first exam, I was  38   to find a 77, C-plus, on my test paper,  39   English was my best subject. I went to Professor Jayne, who listened to my arguments but remained _ 40  .

I decided to try harder, although I didn’t know what that   41   because school had always been easy for me. I read the books more carefully, but got another 77. Again, I   42   with Professor Jayne. Again, he listened patiently but wouldn’t change his   43   .

The last hurdle (障碍) was the final. No matter what   48    I got, it wouldn’t cancel three C-pluses. I might as well kiss the   49    goodbye.

I stopped working hard. I felt I knew the course material as well as I ever would. The night before the final, I even   50   myself to a movie. The next day I decided for once I’d have   51   with a test.

A week later, I was surprised to find I got an A. I hurried into Professor Jayne’s office. He  52 to be expecting me. “If I gave you the As you 53  , you wouldn’t continue to work as hard.”

I stared at him,   54   that his analysis and strategy were correct. I had worked my head off, as I had never done before.

Problem Page

Dear Lifeline,

I shall be getting married in August.My mother wants me to have a white wedding in church, because I am the only daughter, and she wants me to have the kind of wedding that she had.I , on the other hand, would like to have a simple wedding and a small party afterwards for my immediate family and close friends.I don’t want my parents to go to a lot of expense just for one day; I’d rather they spent the money on things that my husband and I will need, that will last us for many years.

Do you agree with me that this is a reasonable point of view? Can you think of a way in which I might persuade my parents to think as I do ?

Yours,

Money-Conscious

Dear Money-Conscious,

We agree that your point of view is reasonable; but reason isn’t everything. Your parents clearly do not mind ‘going to a lot of expense’, as you put it. They would mind more if you prevented them from doing so. There is, in fact, no reason why a white wedding in church should cost a lot of money. Such a wedding can be very simple, yet it can give you the sort of happy memories that your mother has of her own wedding day.

We suggest you meet your mother halfway. Have a simple church wedding and a simple party afterwards. If it means so much to your mother, perhaps you owe it to her to do as she wishes. We are sure that you will not regret it.

 

Dear lifeline,

I have known my girlfriend for six years. The other day, I asked her to marry me, certain that I knew what the answer would be. But she said she wanted to think about it.

I shall be going on holiday soon, and I hoped she would come with me; but now she says she’d rather go on holiday with a friend of hers. Am I losing her?

Yours,

Deeply Worried

Dear Deeply Worried,

Perhaps you were too certain of your girlfriend. Six years is a long time. Perhaps you have been in each other’s packets for too long. Give yourselves a holiday from each other, and then ask her again on your return. We think you will find that she will give you the answer that you want.

56. It is the purpose of the Problem Page to _____.

A.write letters to lonely, troubled people

B.try to find answers to readers’ problems

C.ask readers to give their answers to problems

D.send questions to readers for their answers

57. “Money-Conscious” would like her parents to _____.

A. go to a lot of expense not to buy what she will need

B. give her and her husband the money instead of a church wedding

C. give her money over a period of years

D. spend the money on useful presents rather than on the wedding

58. “Lifeline” suggests a simple church wedding because ______.

A.this is the least expensive kind of wedding

B.you cannot be reasonable about something like a wedding

C.it can be inexpensive yet provide a lifetime’s memories

D.it is the simplest, yet happiest sort of wedding

59. “Deeply Worried” was worried that ______.

A. he might lose his girl-friend while they were on holiday together

B. his girlfriend was losing interest in him

C. he had known his girl-friend for too long

D. he would have to go away on holiday by himself

Which is safer --- staying at home, traveling to work on public transport, or working at the office? Surprisingly, each of these carries the same risk, which is very low. However, what about flying compared to working in the chemical industry? Unfortunately, the former is 65 times riskier than the latter! In fact the accident rate of workers in the chemical industry is less than that of almost any of human activity, and almost as safe as staying at home.

The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this that chemical accidents so newsworthy. Fortunately, they are extremely rare. The most famous ones happened at Texas City (1947), Flixborough (1974), Seveso (1976), Pemex (1984) and Bhopal (1984).

Some of these are always in the minds of the people even though the loss of life was small. No one died at Seveso, and only 28 workers at Flixborough. The worst accident of all was Bhopal, where up to 3,000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before the unfortunate event at Bhopal.

Some experts have discussed these accidents and used each accident to illustrate a particular danger. Thus the Texas City was caused by tons of ammonium nitrate, which is safe unless stored in a great quantity. The Flixborough fireball was the fault of management, which took risks to keep production going during essential repairs. The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonous gas drifted over the town, local leaders were incapable of taking effective action. The Pemex fire was made worse by an overloaded site in an overcrowded suburb. The fire set off a chain reaction of exploding storage tanks. Yet, by a miracle, the two largest tanks did not explode. Had these caught fire, then 3,000 strong rescue team and fire fighters would all have died.

60. According to the passage, the chemical accident that caused by the fault of management happened at _________.

  A. Texas city         B. Flixborough          C. Seveso           D. Mexico City

61. Which of the following statements is TRUE?

A. Working at the office is safer than staying at home.

B. Travelling to work on public transport is safer than working at the office.

C. Staying at home is safer than working in the chemical industry.

D. Working in the chemical industry is safer than traveling by air.

62. From the passage we know that ammonium nitrate is a kind of _____.

A. natural gas, which can easily catch fire

B. fertilizer, which can't be stored in a great quantity

C. poisonous substance, which can't be used in overcrowded areas

D. fuel, which is stored in large tanks

63. From the discussion among some experts we may conclude that _____.

A. to avoid any accident we should not repair the facilities in chemical industry

B. the local authorities should not be concerned with the production of the

chemical industry

C. all these accidents could have been avoided or controlled if effective measures

had been taken

D. natural gas stored in very large tanks is always safe

C

Although man has known about asbestos(石棉) for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for the opening of that first mine.

Mr, Jonhs was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like

ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport(carry)them from Italy to the United States, Mr Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.

Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens ;the rock breaks down into fine, soft, soapy fibers.

Scientists do not know why the rock can be separated easily into threads, but they have found thousands of uses for this fireproof material, of the called the “cloth of stone”.

64. The title that best expresses the main idea of this passage is _____.

A. Asbestos mined in Canada                 B. Fireproof matter

C. A “Wonder” mineral                     D. A new roofing material

65. Johns proved his ability as a salesman by ______.

A. going into the roofing business            B. carrying asbestos from Italy

C. sending a trained scientist                    D. showing the use of asbestos gloves

66. Which is the most important character of asbestos that the author wants to show

us?

A. It is like thread                                           B. It feels soapy

C. It burns easily                                      D. It is unusually heavy

67. The author’s main purpose in writing this passage was to______.

A. show the need for more scientists        B. compare asbestos with other minerals

C. increase the sales of asbestos               D. present facts about asbestos

                            D

Nuclear power's danger to health, safety, and even life itself can be described in one word; radiation.  Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.

At very high levels, radiation can kill an animal or human being outright by killing masses of cells in important organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when

only a few cells are hit, and if they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.

This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.

Radiation can hurt us. We must know the truth.

68. According to the passage, the danger of nuclear power lies in __________.

A. nuclear mystery                                          B. radiation detection

C. radiation level                                             D. nuclear radiation

69. Radiation can lead to serious results even at the lowest level ________.

A.    when it kills few cells                              

B.     if it damages few cells

C. though the damaged cells can repair themselves

D. unless the damaged cells can reproduce themselves

70. Radiation can hurt us in the way that it can _____.

A. kill large numbers of cells in main organs so as to cause death immediately

B. damage cells which may grow into cancer years later

C. affect the healthy growth of our younger generation

D. lead to all of the above results

71. Which of the following can be best inferred from the passage?

A. The importance of protection from radiation cannot be overemphasized

B. The mystery about radiation remains unsolved.

C. Cancer is mainly caused by radiation.

D. Radiation can hurt those who do not know about its danger.

One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world.Fear-producing TV and computer games are leading to a serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.

Each of us has a place in nature we go sometimes, even if it was torn down. We cannot be the last generation to have that place. At this rate, kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes.“If the decline in parks use continues across North America, who will defend parks against encroachment(蚕食)?”asks Richard Louv, author of Last Child in the Woods.

Without having a nature experience, kids, can turn out just fine, but they are missing out a huge enrichment of their lives. That applies to everything from their physical health and mental health, to stress levels, creativity and cognitive (认知的) skills. Experts predict modern kids will have poorer health than their parents―and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component and that play in nature fosters (培养) leadership by the smartest, not by the toughest. Even a tiny outdoor experience can create wonder in a child.The three-year-old turning over his first rock realizes he is not alone in the world.A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.

Kids are not to blame. They are over-protected and frightened.It is dangerous out there from time to time, but repetitive stress from computers is replacing breaking an arm as a childhood rite(仪式)of passage.

Everyone, from developers, to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that cement (增强) love, respect and need for landscape. As parents, we should devote some of our energies to taking our kids into nature. This could yet be our greatest cause.

72. The main idea of Paragraph 2 is that __________.

A.kids missing the sense of wonder outdoors

B.parks are in danger of being gradually encroached

C.Richard Louv is the author of Last Child in the Woods

D.children are expected to develop into protectors of nature

73. According to the passage, children without experiencing nature will _________.

A.keep a high sense of wonder

B.be over-protected by their parents

C.be less healthy both physically and mentally

D.change wild places and creatures for the better

74. According to the author, children’s breaking an arm is ___________.

A.the fault on the part of their parents         

B.the natural experience in their growing up

C.the result of their own carelessness in play

D.the effect of their repetitive stress from computers

75. In writing this passage, the author mainly intends to ________.

A.blame children for getting lost in computer games

B.encourage children to protect parks from encroachment

C.show his concern about children’s lack of experience in nature

D.inspire children to keep the sense of wonder about things around

书面表达

One possible version:

Welcome to the column “English Writing”! Recently the school website has set up a new column called “English Writing” which provides the students the chances to post their composition and communicate with each other. Not only can students improve their writing ability in this way, but they can strengthen their self-confidence.

       The column has lots of advantages. It’s the teacher’s guide on line that has advantage over the other columns. If necessary, the students can have a direct “ask and answer” with professional teachers. It is required that the composition should be related to the students’ life. What’s more, if it is organized well enough, the writer will be rewarded for it.

       Hoping to the students’ participation.
