第三部分:阅读理解(20小题;每小题2分,满分40)

阅读下列短文,从每题所给的四个选项中,选出最佳选项。

A

In the West, advertisements are the fuel that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately (私人地) owned. The government does not give them money.  So where does the money come from?  From advertisements. Without advertisements, there would not be these private businesses.

   Have you ever asked yourself what advertising is?  Through the years, people have given different answers to the question.  For some time it was felt that advertising was a means of “keeping your name before the public”. And some people thought that advertising was “truth well told”. Now more and more people consider it in this way: Advertising is the paid, non-personal, and usually persuasive presentation of goods, services and ideas by some certain sponsors (赞助商) through various media.

   First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is non-personal. It is not face-to-face communication. Although you may feel that a message in a certain advertisement is aimed directly at you, in fact, it is directed at large groups of people. Third, advertising is usually persuasive.  Directly or indirectly it asks people to do something. All advertisements try to make people believe that the product, idea, or service advertised can benefit them. Fourth, the sponsors of the advertisement must show their names. From the advertisement, we can see if the sponsor is a company, or a single person. Fifth, advertising reaches us through old and modern mass media.  Included in the old media are newspapers, magazines, radio, television, and films.  Modern media include emails, matchbox covers, and boards on top of buildings.

56. The existence of the privately owned mass media depends on the support of______.

A. the government                                           B. their owners' families

C. advertisements                                       D. the TV stations

57. The passage seems to say that different ideas of advertising are given due to ______.

A. the change of time                                     

B. the subject of the advertisements

C. people's age difference                

D. people's different opinions

58. Which of the following is considered modern mass media?

A. Newspapers.              B. Emails.                     

C. Magazines.                 D. Films.

59. According to the passage, which of the following statements about advertisements is NOT true?

A. The sponsors are always mentioned.

B. Advertising must be honest and humorous.

C. There is the description of things advertised.

D. Advertising is meant for large groups of people.

答案及解析:

56.C。从第一段So where does the money come from?  From advertisements.可知答案。

57.A。从第二段For some time it was felt that advertising was a means of “keeping your name before the public”. And some people thought that advertising was “truth well told”. Now more and more people consider it in this way... For some time“有段时间”,Now“现在”。

58.B。由最后一句Modern media include emails, matchbox covers, nd boards on top of buildings可知,其他为old media。

59.B。选项B文章没提及。

B

So long as teachers fail to distinguish (differ) between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.

Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to plan cleverly the most efficient(有效的) system for teaching themselves to read. Teaching is also a public activity: It can be seen and observed.

Learning to read involves all that each individual does to understand the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.

If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the long search for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”

When the roles of teacher and learner are seen for what they are, and when both the teacher and learner fulfill them properly, then much of the pressure and feeling of failure for both is got rid of. Learning to read is made easier when teachers create an environment where children are given the chance to solve the problem of learning to read by learning.

60. The problem with the reading course as mentioned in the first paragraph is that ______. 

A. too much time is spent in teaching about reading

B. reading tasks are given with little guidance

C. it is one of the most difficult school courses

D. students spend limited hours in reading

61. The teaching of reading will be successful if ______. 

A. teachers can make their teaching activities observable

B. teachers can teach their students how to read

C. teachers can improve conditions at school for the students

D. teachers can enable students to develop their own way of reading

62. The word “scrutiny” (Paragraph 3) most probably means “______”.

A. unbelief           B. contro

C. inquiry                D. observation

63. The main idea of the passage is that ______.

A. reading is more complicated than believable

B. the reading ability is something gained rather than taught

C. teachers should encourage students to read as widely as possible

D. teachers should do as little as possible in helping students learn to read

答案及解析:

本文从教与学的关系出发,提出了对孩子们的阅读教学方法的看法。

60.A。推断题。根据文章第一段倒数第二句:在阅读活动方面不是时间无休止地投入。也就是说,在阅读上花费的时间太多了。由此可推知此题答案为A。

61.D。细节题。通读 Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny 可知,private 与 not open to public scrutiny 同义,据此可推知答案为D。

62.D。词义猜测题。根据上文private 及单词所在的语句not open to public scrutiny可知,它们同义,由此可推知此题答案为D。

63.B。主旨题。根据文章第一段第二句及全文内容可推知此题答案为B。

C

Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child's physical, sensory, communicational and social development. Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for kindergarten.

There are good reasons for the government to push early childhood education. Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life. Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail.

There are also negative parts to putting a child in formal education programs too early. Time Magazine online explains that “the younger the child the less his chances of catching up with first-grade work”. I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school. Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier.

Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a “false start”, as the gains are lost in middle and high school years. It seems that environment is a bigger factor on life's success than early education. Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children. Perhaps it is time to find other ways to close that gap.

64. The purpose of the government valuing the early childhood education is ______.

A. to develop the children's communication

B. to give orphaned children good care and education

C. to get the children prepared for the kindergarten

D. to train the children formally and regularly

65. According to the studies, which of the following is TRUE?

A. Children with good early education may have a rich life.

B. The orphaned children are usually unhappy in their life.

C. Children without early education can do well at school.

D. Head Start programs are helpful to the poor children.

66....“the younger the child the less his chances of catching up with first-grade work” suggests that ______.

A. the early childhood education is helpless to the child's grade

B. it is good for the young children to receive early education

C. the early education can help the children follow the grade

D. the younger the children are, the more clever they will be

67. The author's attitude toward the early childhood education is ______.

A. puzzling                  B. objective               

C. indifferent                    D. approving

68. The main idea of the last paragraph is that ______.

A. the early childhood education is very necessary

B. Head Start programs have helped the children a lot

C. environment is the most important to life's success

D. better ways should be found to help the poor children

答案及解析:

64. C。细节理解题。根据第一段Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for the kindergarten.可知政府重视早教是为了让孩子们为进入幼儿园做好准备。

65. D。推理判断题。根据第二段Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail.可知Head Start programs对孩子们有帮助。

66. A。 细节理解题。根据第三段There are also negative parts to putting a child in formal education programs too early.和I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school.及上下文可知早教对孩子的成绩没什么帮助。

67. B。推理判断题。从全文来看,作者一直客观地引用他人的研究来介绍早教的利弊,所以B“客观的”是正确答案。A“令人费解”,C“不关心的”,D“赞成”都不正确。

68. D。主旨归纳题。通过对早教利弊的分析,在最后一段指出Perhaps it is time to find other ways to close that gap.所以要寻找更好的方法帮助孩子进步。

D

Gossip(流言蜚语) moves so quickly that few people have time to cover their ears, even if they want to.

“I hate it when others gossip about me,” said Mandy Miraglia, 16, a high school student from California, “but to be honest, gossip about my friends makes me feel I am trusted and belong to the group.” Miraglia is not the only person feeling like that.

Gossip has long been looked down on as little more than nonsense and bad manners. But recent research has shown that gossip has many positive effects on

your social life.

“There has been a trend among people to dislike gossip” said David Sloan Wilson, Professor from the State University of New York in Binghamton, US, “but gossip appears to be a very important form of behavior in a group of friends, defining their group membership.”

For 18 months, Kevin Kniffin, from the University of Wisconsin, US, researched the behavior of 50 people. He found that gossip levels peaked when a sports team included a slacker,_someone who regularly missed practices or showed up late. Other members of the team would soon start to joke about the slacker's shortcomings behind his back, because they thought they were bad for the whole team.

Gossip about the mistakes of senior members helps newcomers rebuild their confidence after a failure.

It also helps relieve social and professional anxiety. Longterm studies show that people around the world devote from a fifth to twothirds or more of their daily conversation to gossip, and men appear to be just as eager for gossip as women.

It is hard to judge gossip, but it is more powerful than you think.

69. The author would probably agree that ______.

A. gossip is bad manners

B. gossip has many good effects

C. gossip is somewhat like nonsense

D. gossip is more powerful than advice

70. What does the underlined word “slacker” mean according to the context?

A. Someone who values the team benefit much.

B. Someone who does not do what they should do well.

C. Someone who is active in sports.

D. Someone who shows no much interest in sports.

71. Which of the following is NOT true according to the passage?

A. Gossip is a useful way of building group membership.

B. Gossip can possibly make someone confident.

C. Generally, women are fonders of gossip than men.

D. Actually, everyone gossips to some degree in their daily conversation.

答案及解析:

69B。由第三段后半段及下文叙述可知,作者认为流言蜚语也有很多好的影响。

70B。由该词后someone who regularly missed practices or showed up late可知B项最佳。

71C。由倒数第二段最后一句men appear to be just as eager for gossip as women可知C项错误。

E

Sunday is more like Monday than it used to be. Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant (不相关的)A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.

The law in almost all states used to require stores to close on Sunday; in most, it no longer does. It used to keep the schools open in all seasons except

summer; in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?

  These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years but unless we meet the truant officer (学监) we may well think that we should go to school due to social custom and parents' demand rather than to the law. As adults we are familiar with “extra pay for overtime working” but less familiar with the fact that what constitutes(构成) “overtime” is a matter of legal definition. When we turn the clock forward to start daylightsaving time, have we ever thought to ourselves: “Here is the law in action” As we shall see, there is a lot of law that has great influence on how to organize and use time: compulsory education law, overtime law, and daylightsaving lawas well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.

72. By saying “Sunday is more like Monday than it used to be” the writer means that ______.

A. work time is equal to rest time           

B. many people have a day off on Monday

C. it is hard for people to decide when to rest

D. the line between work time and rest time is unclear

73. The author raises the questions in paragraph 2 to introduce the fact that people______.

A. fail to make full use of their time              

B. enjoy working overtime for extra pay

C. are unaware of the law of time                  

D. welcome flexible working hours

74. According to the passage, most children tend to believe that they go to school because they______.

A. need to acquire knowledge                

B. have to obey their parents

C. need to find companions      

D. have to observe the law

75.  What is the main idea of the passage?

A. Our life is governed by the law of time.   

B. How to organize time is not worth debating.

C. New ways of using time change our society.

D. Our time schedule is decided by social customs.

答案及解析:

时间法则在我们的生活与工作中无处不在。但是在当代社会,人们对工作与休息的界限的划分比较模糊。

72.D。第一段说,原先只在白天才工作的地方现在开门营业到半夜。在网上,什么是休息时间或工作时间都没有关联。从这些叙述判断,其含义是D,一天中什么时间是休息时间,一个星期中哪天是休息时间,这些

区别现在都很模糊了。

73.C。第二段作者列举事例并提出疑问,然后说“这些问题不好回答”,问题在于我们没有意识到“时间的法则”。

74.B。第三段说,我们会觉得,我们要上学读书,因为这是社会习俗,是父母的要求,而不是法律的规定。

75.A。我们的生活受到时间法则的约束,法则约束着我们的学习、工作与休息时间的安排。这是本文的主题。

第四部分:书面表达(共两节,满分35)

第一节:任务型读写(共10小题;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词。注意:每空一词。

Have you ever wondered why there are so many skin colours in the world? Do you know why people living in particular areas usually have a certain colour? Biology and history are the two reasons for this.

Skin contains something called melanin, which determines a person's skin colour. The more melanin a person has, the darker his or her skin will be. The amount of and production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with strong sunlight, his or her skin will protect itself by producing more melanin, making the skin darker. In a place with less sunlight, a person's body will produce less melanin, making the skin lighter.

Skin colour is also affected by another source-vitamin D. Humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, which causes vitamin production in the skin. Melanin protects skin by absorbing sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark-skinned person will produce less vitamin D than a light-skinned person when they received the same amount of sunlight.

The connection between vitamin D production and skin colour is clear when we look at evolution. The earliest humans lived in Africa, their dark skin covered with hair. When they moved to places that had less sunlight, their bodies produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. Their skin gradually got lighter and they lost hair. Now, people who live in areas with strong sunlight, like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.

Evolution has given us a rainbow of skin colours. Humans have always had melanin to determine our skin colour. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin colour.

On 4th Nov., 2009,the Shanghai municipal government announced that China's central government has officially approved the Shanghai Disneyland Project.

People have different opinions of the project. Some think it is  not necessary to build another one in China since there already exists one in HongKong. Also it is hard to attract large numbers of tourists, given current financial situation. It may affect the environment as well. But there is another voice. Other people think it will be a good choice for them, especially children, to spend their holidays in the park. Many jobs will be created, which is good for local economy. The opening of the park will definitely promote the development of transportation and tourism.

Personally, I would love to see the park completed as soon as possible. I am sure people will have great fun there.
