The yearly marathon (a long-distance running race of 42.195 km) in

my town usually occurs during a heat wave. My job was to follow behind

the runners in an ambulance 36 any of them needed medical attention.

“We’re supposed to stay behind the 37 runner, so take it

slowly,” I said to the driver, Doug, as the race started.

The front-runners started to 38 and then my eyes were 39 to the

第三部分. 阅读理解（共15小题；每小题2分，满分30分）

阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项。

(A)

Now we are always hearing about road accidents and when we’re in a car we try to drive carefully, but how many of us take the same degree of care in our homes? Any large hospital will tell you the number of

accidents that happen in the home is almost the same as those on the road. I don’t pretend to be an expert, but I’ve thought a lot about how and why these accidents happen and what we can do to prevent them.

One of the commonest and most dangerous causes of home accidents is wrong and careless use of electrical equipment. People will continue

to use a loose plug or pull out a plug without first turning off the power. In spite of warnings, one will carry an electric heater into the bathroom

when he is going to have a bath. Sometimes one forgets to cut off the power before mending a lamp or something else. All this will cause accidents. So the rule about anything that works by electricity is: Switch off before you touch anything and don’t pretend you know when you actually don’t.

If you’ve got children in the house, it’s always best to keep medicines of any kind out of their reach. Otherwise, they may be taken for candies or a new kind of drink. When there are older people living with you, you have to take particular care in a number of ways in order to make them safe and happy.

Fire, of course, is always a risk. So, remember not to dry clothes in front of fires, or leave stoves in the middle of rooms where they can

easily be knocked over. And don’t forget to keep the children away from fire. Smoking, too, causes fire. So you’d better give it up. Safety first may mean a little more time and care, but it may save

you a lot of trouble.

56. The writer thinks the reason why there are so many accidents in our home is that we are _______.

A. less careful in our homes than in a car B. more careful in our homes than in a car

C. as careful in our homes as in a car D. not so careful in a car as in our homes

57. The writer advises you _______ about the use of electrical equipment. A. to appear as if you know everything

B. to pretend that you don’t know anything C. to pretend that you know everything

D. not to think you know everything

58. It’s best to keep medicines in places that children can’t __________.

A. get on B. get to

C. get in D. get over

59. One way to prevent fires at home is to _________. A. leave stoves in the middle of the rooms

B. dry clothes near stoves

C. tell children to stay away from fire

D. smoke away from fires

（B）

In a traditional Chinese family, women are expected to do the housekeeping and leave the “other business” to men. However, the appearance of the full-time “househusband” is changing traditional family.

A survey in Beijing, Shanghai, Guangzhou and Shenzhen shows that 22 percent, 73 percent, 34 percent and 32 percent of white-collar male

workers, aged between 28 and 33, would be prepared to do the housekeeping if the conditions were right.

Yang Wenhui, 32 years old, worked at the office of a company prefer to quit the job. “My job was dull and steady. I was not promoted. My wife, in contrast, really likes her job. So, after our baby was born, I chose to stay at home and take care of the family while my wife works full-time outside the home,” said Yang.

Sociologists have found the full-time househusband emerges in three main situations.

Firstly, if the wife is ambitious, well-paid and has good job prospects, while her husband is paid poorly and has no job prospects, it makes economic sense for the woman to become the main income earner for the household. Secondly, if the wife is tired of household chores and eager to work outside the home, her husband may forfeit his job. Thirdly, if the husband can do his work at home, he may take this choice as it allows him more time to take care of the family.

Influenced by traditional ideas, some families with full-time househusbands prefer others not to know about their arrangement, concerned people would laugh at a husband with “no prospects” or wife who is “too strong”.

Zhou Wei said he has become usual to being a full-time househusband although his relatives doubted this when they gathered during the

holidays. “A happy life is the most important thing, not other peoples’

opinions,” added Zhou.

60. The reason for Yang Wenhui quitting his job is that ________.

A. it is too difficult for him to do it B. it is too boring for him to do it

C. he is too old to go on doing it D. his wife wanted him to quit it

61. In which situation is a man unlikely to become a full-time househusband?

A. He can earn enough money to keep family and has a good job prospects. B. He can earn much less than his wife and will never get promoted. C. His wife hates housework and is busy with her work outside. D. His job can be done at home and he would like stay at home. 62. Which of the following is TRUE according to the passage?

A. A full-time househusband is a man without prospects in life. B. A full-time househusband is much weaker than his wife.

C. A full-time househusband is willing to share his experience with his relatives.

D. A full-time househusband can also enjoy happiness from housework. 63. The underlined word “forfeit” probably means ________. A. appreciate B. quit C. continue D. escape (C)

Have you ever lied to your parents that you came back late from school because you stayed to finish some homework when actually you went to play

computer games or have fun with your friends? If students in Taiyuan Yuying High School in Shanxi Province lied in the past, they will not

be able to do so in the future. A smart card, Electronic Identity Card, will be introduced this week at the school. The card, which contains a tiny chip, includes a student’s name, photo and their student number on the face of the card . With this

ID, parents will know exactly when their kids arrive and leave the school via(通过) a mobile phone message or an email. “There’s a card reader equipped in each classroom. The system will send the information to students’ parents if they have applied for this service,” explained Kang Jinfeng, a technician in the school. The school hopes the card will make the students safer and better organized.

“The environment around the campus has become busier with lots of

things to distract (使分心) students. Some students go to the Internet cafes nearby instead of going home immediately after school. Also, many

parents worry about their children’s safety on the way home as there have been lots of student accidents recently,” said Fu Hongyan, headmaster of the school.

Parents and students are eager to see how the new smart card works, for the school is the first one in the province to start the program.

“Although I hope my child can manage his time well, this card will help me know more about him,” said Wang Liping, a Senior 3 student’s mother. Apart from information on attendance (出勤), parents will also be informed of their children’s performance, homework comments and examination results. Although parents welcome the move, some students think it will affect their freedom and privacy. “It seems that I am being

watched over everywhere and every second. I used to play basketball after school, but now I may have to explain to my parents every day why I get home late. I want to be more independent to deal with my own things,” said Liu Jida, a Senior 3 student . “I would rather that my parents did not know my bad exam results, but the card will tell them everything about my studies,” complained Zhang Xu, a 17-year-old boy.

. If the parents ______, they can use the information in the card reader.

A. have a mobile B. have a computer

C. have a TV set D. have applied for the service 65. The school will use Electronic Identify card for the sake of ________. A. money B. the safety of the school

C. the management of the school D. the safety of the students and better organization

66. According to the article , _______ don’t like the new ID.

A. the leaders of the school B. the teachers of the school C. the parents of the students D. some students

67. We can conclude from the text that there will be ________ students going to the Internet cafes nearby after school .

A. more B. fewer C. no D. many

(D)

Why you may wonder, should spiders be our friends? Because they

destroy so many insects, including some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour (吞食) all our crops and kill our cattle, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beast who eat insects, but all of them put together kill only a very small amount of the number destroyed by spiders. Moreover, unlike some of the insect eaters, spiders never do the least harm to us or our belongings.

Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and an insect never more than six. How many spiders are engaged in the work on our behalf ? One authority

（权威人士）on spiders made a research on spiders and found that there were more than 2,250,000 in one acre (英亩); that is something like 6,000,000 spiders of different kinds on a football field. Spiders are

busy for at least half the year in killing insects. It is impossible to

make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by the spiders in Britain in one year would be greater than the total weight of all human beings in the country.

68. Spiders should be our friends, because __________. A. they only eat harmful insects

B. they are great insect-eating animals

C. they destroy large numbers of insects which do harm to the human race

D. their harmfulness is the least

69. One authority on spiders estimated ________.

A. that there were more than 2,250,000 insects in a grass field in the south of England

B. that every football field in England had 6,000,000 spiders. C. the quantity of different spiders in England was very big

D. that there were 6,000,000 kinds of spiders on a football field 70. Which one of the following statements is the main idea?

A. Spiders, the greatest insects-eating animals, protect us from

being destroyed by harmful insects and they should be our friends B. Spiders are not insects but in fact animals.

C. There are great numbers of spiders engaged in destroying harmful insects on behalf of the human race.

D. The weight of the insects eaten by spiders in one year is greater than the weight of all people in England

第Ⅱ卷（35分）

第一部分：任务型阅读（每小题1分，满分10分）

请认真阅读下面短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。

注意：每空格1个单词。

The family sphere(范围) used to be defined by its isolation（隔离）from the public realm. There was the public male realm（领域）of \"rational accomplishment\" and cruel competition, and the private female and child-rearing sphere of home, intuition（直觉）and emotion. The private

realm was supposed to be isolated from the realities of adult life. For both better and worse, television and other electronic media tend to break down the difference between those two worlds. The membrane around the family sphere is much more permeable(可渗透的). TV takes public

events and transforms them into dramas that are played out in the privacy of our living rooms, kitchens and bedrooms.

Parents used to be the channel through which children learned about

the outside world. They could decide what to tell their children and when

to tell it to them. Since children learn to read in stages, books provide

a kind of natural screening process, where adults can decide what to tell

and not tell children of different reading abilities. Television destroyed the system that separated adult from child knowledge and separated information into year-by-year slices for children of different ages. Instead, it presents the same information directly to children of How Television Changes Childhood?

Main comparisons Contexts Homes used to be isolated from the ___2___realm. Homes nowadays are __3__to the outside world. Distance between ___1__and the outside. all ages, without going through adult filters.

So television presents a real challenge to adults. While a parent can read a newspaper without sharing it with children in the same room, television is accessible to everyone in that space. And unlike books, television doesn't allow us to flip（翻转）through it and see what's coming up. We may think we're giving our children a lesson in science by having them watch the Challenger take off, and then suddenly they learn about death, disaster and adult mistakes.

Books allow adults to discuss privately what to tell or not tell

children. This also allows parents to keep adult material secret from

children and keep their secret keeping secret. Take that same material and put it on The Today Show and you have 800,000 children hearing the very things the adults are trying to keep from them. \"Television takes our kids across the globe before parents give them permission to cross the street.\"

More importantly, children gradually learn that adults are worried and anxious about being parents. Actually, television has also places families under a lot of stress.

In the past, children might learn __4__about the outside world with the help Media through which children can obtain of parents and ___5___. information More information is got directly through TV and other electronic media, which breaks down the __6___ between adult world and the child world. Traditionally, kids could only knew what they should learn at their age, _____7___ of the information children get carefully___8___by their parents. Everything can possibly be known by children, including many aspects of ___ 9__ life. Effects on family education Families are now under greater stress than Parental instruction before. Adults are anxious about being parents and faced with new __10_____. 第二部分： 单词拼写 （共10小题；每小题0.5分，满分5分） 根据所给句子意思以及汉语或首字母提示，写出下列各句中所缺单词的正确形式。

I'm writing to you about the industrial area which will be built near our town. Recently the local government has decided to build an industrial area, which has aroused heated argument.

Some agree that we should build the industrial area. If we do so, many new jobs can be created, which will increase people's income and improve their living standards. What's more, it can push the development of the local economy and the natural resources can also be made good use of.

But others are against the idea, because they think it will pollute the environment. They believe that it will produce noise which will disturb people's peaceful life. Furthermore, a lot of farmland will be built on.

Personally, I agree with the second view. Economic development

should never be at the cost of the environment we must pay attention to sustainable development so that we'll have a better hometown in the future.

Yours truly,

Li Hua
