   I ran into a stranger as he passed by. “I'm so sorry!” was my reply. Then he said, “Excuse me too. I wasn't  36

watching for you.” We were very polite. Then we went on our way after saying  37.

   But at  38 , a different story is told. How we treat our loved ones, young and old. Later in the kitchen, as I  39  our meal, my daughter walked up to me, very still. When I turned, I  40  knocked her down. “Get out of the way!” I shouted. She stepped away silently, with her little heart  41 .

   That night, when I lay   42   in bed, God's quiet voice spoke to me and said, “While  43  with a stranger, you are calm and polite, but with those you love, you are QUICK to excite... Go look around on the kitchen floor, you'll find some flowers there by the  44 . Those are the flowers she brought for you. She  45  them herself-- pink, yellow, and your favorite blue. She stood there quietly, and you never saw the  46  in her eyes.”

   By this time, I felt sad and small and now my own tears had begun to fall. I quietly went and knelt by her  47 : “Wake up, my dear,” I said, “Are these the flowers you picked up for me?” She smiled, “I found them out by the tree. I  48 them in a napkin, just for you. I knew you'd like them, especially the  49 .” I said, “I am so sorry that I missed them today... And I  50  have shouted at you that way.”

   And she whispered, “Mommy, that's okay.. I still love you  51 .” I hugged her and said, “I love you, too and I LOVE the flowers.”

   Do you know that: if you die tomorrow, the  52  you are working for could easily replace you in a matter of days. But the family you leave  _53  will feel the loss for the rest of their lives. And come to think of it, we pour ourselves more into our  54  than into our families--an unwise investment indeed.

A

People fell in love with Elizabeth Taylor in 1944, when she starred in National Velvet-the story of Velvet Brown, a young girl who wins first place in a famous horse race. At first, the producers of the movie told Taylor that she was too small to play the part of Velvet. However, they waited for her for a few months as she exercised and trained―and added three inches to her height in four months! Her acting in National Velvet is still considered the best by a child actress.

Elizabeth Taylor was born in London in 1932. Her parents, both Americans, had moved there for business reasons. When World war II started, the Taylors moved to Beverly Hills, California, and there Elizabeth started acting in movies. After her success as a child star, Taylor moved into adult roles and won twice for Best Actress: Butterfield 8(1960) and Who’s Afraid of Virginia Woolf? (1966)

Taylor’s fame and popularity gave her a lot of power with the movie industry, so she was able to demand very high pay for her movies. In 1963, she received $1 million for her part in Cleopatra―the highest pay received by any star up to that time.

Elizabeth Taylor is a legend of our time. Like Velvet Brown in National Velvet, she has been lucky, she has beauty, fame and wealth. But she is also a hard worker. Taylor seldom acts in movies any more. Instead, she puts her time and efforts into her businesses, and into helping others ― several years ago, she founded an organization that has raised more than $40 million for research and education.

56. The producers didn’t let Taylor play the part of Velvet at first because they thought she ____.

A. was small in size                                         B. was too young

C. did not play well enough                              D. did not show much interest

57. What Elizabeth Taylor and Velvet Brown had in common was that they were both _____.

A. popular all their lives                                  B. famous actresses

C. successful when very young                          D. rich and kind-hearted

58. Taylor became Best Actress at the age of          .

A. 12             B. 28                     C. 31             D. 34

59. In her later life, Elizabeth Taylor devoted herself to             .

A. doing business and helping others                  B. turning herself into a legend

C. collecting money for the poor                       D. going about research and education work

B

If you think a Web site designed especially for complaining sounds unique, then think again. If you have a complaint, there are hundreds of sites that allow you to get it off your chest. Sites exist for complaining about such things as defective products, government inefficiency, and offensive advertising. There are even sites where you can complain about anything that bugs you, including love, family, or just the weather. These Web sites won’t actually do anything about your problem; they just let you blow off steam. Here’s a sampling of complaints people have written:

1. Something I can’t stand is pencils! They need to be sharpened after every page you write. And then don’t you hate it when they start to make a scratching noise?

2. Have you ever noticed that in most schools you have chairs with armrests to write on attached to the right-hand side of the chair only? Where are the desks for left-handed people? It’s very uncomfortable for us “l(fā)efties” to use these desks made for right-handed people!

3. I see red every time I get my credit card bill from the bank. There’s always a check for a large amount attached with an invitation to sign it and spend it on “anything I want.” I have enough sense to rip it up and throw it away, but I bet a lot of people don’t. They don’t realize that when they use the “free check”, the expense gets put on their credit card bill. Boy, they must be surprised when they get that bill! I think that banks shouldn’t be tempting people with those checks.

4. It isn’t fair that only the US controls the Internet! I go to fill in a request for a catalog or a prize or a free offer, and I find it’s limited to residents of the United States. I live outside the US, and it’s frustrating!

60. If you have a complaint and go to some Web sites, ___________.

   A. your problem will be settled                                  B. you won’t be angry any more

   C. you are allowed to check your chest                            D. you will be bugged

61. What is the problem with those checks that people complained about?

   A. People can buy anything without paying the bill.         B. People usually throw them away.  

C. People are surprised to get the checks.          D. People couldn’t realize they’d used too much with the check

62. Why do people complain about the Internet?

   A. People can’t find the internet outside the United States B. People can’t get a free offer in the United States.

   C. People can’t get a free offer outside the United States.          D People can’t fill in a request for a free offer.

63. What could be the best title for the passage?

   A. Excellent Web Sites.                                          B. Complaining Online.

   C. Sampling of Complaints.                                       D. Writing out Your Complaints.

C

To be “historically minded” is to see things in relation and in perspective, and to judge tolerantly. We must remember how differently men have thought and acted in different times. We must always keep an open mind, ready to receive and weigh new evidence. If we grasp this idea, we will never think that a historian is someone who can remember dates. That childish idea is like calling a man a statesman because he can remember the names of voters in his district. A waiter could remember more names and a telephone operator more numbers than the greatest historian.?

The true historian is not content to take all his facts from other historians. Today he makes sure that his statements are based on sound “documents” or “sources” which go back to the time of the facts themselves. But the historian needs always to be in his guard not to be misled by his sources. A document may not be a real one. Its author may be lying on purpose for some reasons. He may be so greatly influenced by national, religious, party or personal backgrounds as to be totally unfair to the other side. If honest, he may be misinformed as to the facts and mistaken in his inferences.?

Anyone who reads the accounts published in the different countries concerning the causes and results of wars will realize that the historian needs caution and training in handling these sources. The trained historian asks first: “Did this writer mean to tell the truth?” and second; “Was he in a position or frame of mind to tell the truth even if he wants to?” Every statement must be patiently weighed and tested and combined with all other available information in order to get at the truth.?

64  A “historica1ly minded” researcher ____.?

A. always keeps an open mind to history?  B. looks at one historical event without relating it to another

C. sees things from a single point of view?               D. refuses to accept new evidence?

65. In Paragraph l the author means to illustrate that ____.?

A. different men think and act differently?

B. the study of history is not merely a matter of remembering dates?

C. a statesman can remember the names of voters in his district?

D. a waiter can remember more names than the great historians?

66. The true historian should base his statements on ____.?

A. findings of other historians?                               B. documents created at the present time?

C. his own inferences?                                           D. sound historical materials?

67. Which of the following is the topic of Paragraph 3? ?

A. Some historical documents may not be real.?              B. Historians should be careful about their sources.

C. Some authors may not be honest.??     D. Historians may be influenced by their own backgrounds.?

Effective environmental protection laws and other measures have led to the improvement of water quality in Tai Hu lake in Jiangsu Province.

The news was announced by officials from the provincial environmental protection bureau, which has just conducted an inspection of the lake area.

By the end of September, about 80 per cent of industrial pollutants met required standards and the lake is expected to be cleaner by the end of the year, officials said.

According to targets set by the State Environmental Protection Administration, all polluting enterprises must meet set standards by the end of this year or they will be shut down.

The Taihu Lake area, which surrounds the cities of Suzhou, Wuxi and Changshou, is one of the most economically developed areas in the country and has long enjoyed a reputation as the “l(fā)and of fish and rice”

However, the quality of water in the lake has been deteriorating（惡化）at an alarmingly rate in recent years, which has caused concern from the government and local people.

 Pollution is so high mainly because people do not have enough environmental awareness and have put economic benefits ahead of their surroundings.

Economic development in the area has been rapid with hundreds of factories being built. But officials say most of these do not have the anti-pollution equipment or measures they should have.

Because of the lack of waste treatment facilities, wasted water and other rubbish from residential areas in nearby towns and villages flow into rivers which are connected to Taihu Lake. This also contributed to the lake’s pollution.

 Realizing the seriousness of the situation, the provincial and local governments began to tackle the problem.

 Experts were invited to offer suggestions and laws and regulations were issued. All newly built factories and enterprises in the lake area were required to install necessary anti-pollution facilities before they can go into operation.

Also, some wasted water treatment works will be built in the three cities. 

72. We can know from the text that the Taihu lake area is a place where_____.

A. the water in the lake was very clear                B. the factories are trying their best to protect the water

C. the economy has been developed best in the country

D. the people and the government are paying more attention to the pollution.

73. Most of the factories now _____

A. are sending the quite a little pollutant to the lake           B. can satisfy the required standards

C. have to stop their production                                       D. have to think of other ways to survive.

74. The reason why the pollution became so serious here is that ___

A. the people here didn’t know how to deal with the pollution

B. the factories thought the economy was the first

C. the local governments didn’t know the situation at all

D. the factories had no the technology to control the pollution.

75. After reading the text, we can learn that_____.

A. the economy development will do harm for the environment

B. we can not avoid polluting if we wish to develop our economy.

C. only the experts can deal with the pollution

D. pollution can't be the result of the economy development

第二節(jié)：書面表達(dá)（滿分25分）

根據(jù)提示寫一篇120字左右的短文。

時下，很多學(xué)生帶手機(jī)上學(xué)。為此，某英語報在你校組織了一場討論。討論的主題：中學(xué)生是否有必要帶手機(jī)去學(xué)校。請你根據(jù)下表提供的信息，給報社寫一封信，客觀地介紹討論情況。

大多數(shù)同學(xué)認(rèn)為

大多數(shù)老師認(rèn)為：

你的觀點：

可方便與家長、同學(xué)聯(lián)系；是一種時尚。

中學(xué)生年齡尚小，還不能自控；用手機(jī)玩游戲，發(fā)短信浪費時間；容易引起攀比。如須打電話學(xué)校里有各種電話可供使用。

追求時尚可以理解，

但學(xué)習(xí)是首要任務(wù)。

注意：1．信的開頭已為你寫好。

2參考詞匯：攀比：vie with…  在校園內(nèi)：on the campus
