第三部分阅读理解（共20小题；每小题2分，满分40分）
A
Zhoukoudian is a small village situated about 50 kilometers to the southwest of Beijing. In the 1920s, archaeologists discovered some prehistoric human bones there which changed people’s view of China’s history. They came from an unknown species of man and were the first evidence of human life in China thousands of years ago. The remains were three teeth!
In 1929, a complete skull was also discovered. Eventually, archaeologists found almost 200 items, including six skulls and more than 150 teeth. These discoveries proved the existence of a human species who lived in the area between 700,000 and 200,000 years ago. Four sites where Beijing Man and his relatives lived were discovered on the northern face of Longgushan. They lived in the caves in the area. However, the life span of Beijing Man was short. About 70% of the people probably died before the age of 14. Fewer than 5% lived to the age of 50. Ashes were found alongside the fossils which showed they had used fire for cooking food and also for light, warmth, and protection against wild animals. This is the earliest evidence of the use of fire anywhere in the world. They also made tools of bones and stones. Unfortunately, when Japan invaded China in 1937, excavations (发掘) at the Beijing Man Site stopped and most of the fossils disappeared, including a Beijing Man skull. After the People’s Republic of China was established in 1949, the work started again. Zhoukoudian was listed as a World Heritage Site in December 1987. It has not only given us important information about prehistoric Asian societies, but also provided amazing evidence about the process of evolution. Today, parts of the caves have been badly affected by rain. Some areas are almost completely covered in weeds, causing serious damage. Pollution from the nearby factories has also contributed to the problem. This is a very serious matter and the Chinese Academy of Sciences is trying to raise public awareness of it.
56. Archaeologists _________.
A. thought that Zhoukoudian was a beautiful village
B. thought that the findings in Zhoukoudian would n’t change the history of China
C. discovered some prehistoric human bones in Zhoukoudian
D. thought that the findings in Zhoukoudian are the first evidence of human life in
Asia

D. The digging of Zhoukoudian is famous and is well-funded.

B
Imagine a boy from a small village in East Africa. He, since a very early age, has been looking after cattle. At twelve years old he knows more about cattle than most of you. However, he has never been to school. Has this boy had any education?
Education is discovering about ourselves and about the people and things around us. All the people who care about us — our parents, brothers, sisters, friends — are our teachers. In fact, we learn something from everyone we meet. We start learning on the day we were born, not on the first day we go to school. Every day we have new experiences, like finding a bird’s nest, discovering a new street in our neighborhood, making friends with someone we didn’t like before. New experiences are even more fun when we share them with other people.
Encouragement from the people around us enables us to explore things as many as possible. As we grow up, we begin to find out what we are capable of doing. You may be good at cooking, or singing or playing football. You find this out by doing these things. Just thinking about cooking doesn’t tell you whether you are good at it.
We learn so much just living from day to day. So why is school important? Of course you can learn some things better at home than at school, like how to do the sh opping, and how to help old or disabled people who can’t do everything for themselves. At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.
61. The writer takes the African boy as an example to show that _______.
A. African children are very poor
B. some children are unlucky
C. there are many kinds of education
D. schools are of great importance
62. In the opinion of the writer, .
A. we have to learn from the people around us
B. the school is not important at all
C. only people who care for us can teach us
D. education takes place everywhere
63. One can find out what he / she is good at by _.
A. what people encourage him / her to do
B. the teachings of those he / she meets
C. thinking about it when growing up
D. trying and practising things
64. The passage tells us that _ .
A. everyone gets education from the day he or she was born
B. different classes of people receive different kinds of education
C. the school is absolutely necessary if one wants to understand the world
D. everyone will find out what he or she is good at
65. According to the last paragraph, we know that .
A. the school is not so important as our living places
B. the school enables us to understand the world in other ways
C. the school teaches us things which are useless at home
D. the school cannot prepare us for our daily lives
C
There are two types of people in the world. Although they have an equal degree of health and wealth and other comforts of life, one becomes happy, while the other becomes unhappy. This arises from the different ways in which they consider things, persons and events and the resulting effects upon their minds.
People who are happy fix their attention on the convenience of things. They enjoy all cheerful things. Those who are unhappy think and speak only of unpleasant things. Through their remarks, they sour the pleasure of society, offend many people, and make themselves disagreeable everywhere. If this turn of mind is founded in nature, such unhappy people should be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation（模仿）. It grows into a habit, unknown to its possessors. The habit may be strong, but it can be cured when those who have it realize its bad effects.
Although this attitude is mainly an act of the imagination, it has serious results since it brings on deep sorrow and bad luck. If such people aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone speak a word in favor of their hopes. If they are criticized, no one will defend or excuse them, and many will join in criticizing their wrong doings. So they should change this bad habit and stop worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, they will have a disagreeable time, especially when someone becomes mixed up in their quarrels.
66. How does the writer tell the happy from the unhappy?
A. According to their degree of health.
B. According to their wealth.
C. According to their attitudes to the same thing.
D. According to their habits.
67. The phrase “sour the pleasure of society” probably means “________”.
A. have a good attitude towards social life
B. make others unhappy
C. tend to scold others openly
D. enjoy the pleasure of life
68. We can conclude from the passage that ________.
A. we should pity all unhappy people
B. unhappy people are dangerous to social life
C. people can get rid of the habit of unhappiness
D. unhappy people can not understand happy people
69. If such unhappy people insist on keeping the habit, the author suggests that people
should ________.
A. not have any communication with them
B. show no respect for them
C. persuade them to recognize the bad effects of their habits
D. quarrel with them until they realize their mistakes
70. In this passage, the writer mainly ________.
A. describes two types of people
B. laughs at unhappy people
C. suggests ways to help unhappy people
D. tells people how to be happy in life
D
Every day, more people around the world are using the Internet to communicate with each other.
The blog is one form of communication that has increased in popularity. Through these personal web sites, people can share their lives, ideas and opinions with anyone on the Internet. Millions of people throughout the world are creating and reading blogs.
People of all ages have blogs. For young people, they are a way to show their writings and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas, experiences and concerns about their work with other teachers.
Many web sites offer free services which allow people to create personal web pages and to fill them with writings and pictures. These sites include “MySpace”, used mainly by teenagers and young adults. About 120,000,000 people use MySpace and share messages and pictures online. It is the most popular social networking site on the web.
YouTube is another Internet site that has become more popular this year. This web site lets anyone create, share and watch short videos. People can watch almost anything on YouTube: news, sports and entertainment events in their own homes, including videos of people singing or dancing, or animals doing funny things. YouTube says that people watch at least one hundred million videos on the site every day. Three young men created YouTube almost two years ago as a personal video sharing service. They recently sold it to Google for more than one and a half billion dollars.
Games and entertainment have also become a larger part of the Internet this year. One Internet social site is called SecondLife. It is an online world in which computer users create a new self and live a different life. They get married, build homes, operate businesses, buy and sell goods, work, play and attend school. About two million people take part in SecondLife.
71. What can be inferred in the passage?
A. Nowadays, people all over the world use blogs to communicate with each other.
B. More and more people are using blogs as a way of communication.
C. Teachers can use blogs to help their students in their computer classes.

阅读下面的短文，并根据文章后的题目要求回答76-80小题。
Health care or healthcare is the prevention, treatment, and management of illness and the preservation of mental and physical well-being through the services offered by the medical and allied health professions.
The healthcare industry includes the delivery of health services by doctors and other allied health departments. Usually the health services receive payment from the patient or from the patient’s insurance company, although they may be government-financed (such as the National Health Service in the United Kingdom) or delivered by charities or volunteers, particularly in poor countries.
The healthcare industry is one of the world’s largest and fastest growing industries, consuming over 10 percent of the GDP (Gross Domestic Product) of most developed nations. Health care can form _______________. In 2003, health care costs paid to hospitals, doctors, nursing homes, diagnostic laboratories, pharmacies, medical device manufacturers and other components of the health care system consumed 15.3 percent of the GDP of the United States, the largest in the world. In 2001, for the OECD (Organization for Economic Co-operation and Development) countries, the average was 8.4 percent with the United States (13.9%), Switzerland (10.9%), and Germany (10.7%) being the top three.
The more generally accepted view of healthcare is that improvements result from advancements in medical science. The medical model of health focuses on the removing of illness through diagnosis and effective treatment. In contrast, the social model of health places emphasis on changes that can be made in society and in people’s own lifestyles to make the population healthier. It defines illness from the point of view of the individual’s functioning within the society r ather than by
monitoring for changes in biological or physiological signs.

In 1991, two German tourists found part of a body in the ice when walking along a path in the Alps. It turned out to be a man from the Stone Age.
Otzi, as the archaeologists called him, lived about 5,300 years ago. At that time people in Egypt were building the pyramids. We know that he was a farmer because there were pieces of corn in his clothes. He was probably taking his sheep and goats into the mountains when he died.
Otzi has changed our ideas about the Stone Age. Before Otzi, archaeologists thought the copper didn’t arrive in Europe until about 2,000 BC. Otzi, however, was carrying a copper axe around 1,300 years earlier. He was also carrying a bow and arrows, a knife and some wooden tools. He was wearing warm, waterproof clothes and leather boots. These things show that Stone Age people were a lot more advanced than we thought.

The city stands on the seaside. It is a beautiful place for people to live in and every year many people come here to enjoy their summer holidays. Its economy has been developing rapidly in the past ten years. New factories, houses, and roads have been built. More schools and hospitals are available for its people. Free gardens and parks are everywhere so that people can enjoy their outdoor life whenever they want. However, there are still some problems, such as water and air pollution and heavy traffic in rush hours. In my opinion, Ningcheng City should develop its economy scientifically. The government should also make a great effort to control its population and the using of cars. In that way, we’ll have a better city in the future.
Welcome to my hometown.
Yours,
Li Hua
重点解析
21. B。interrupt“暂停，中断”，而break in on sth短语才有“打断”的意思，pause
“暂停”，是不及物动词，cut意为“停止”。
22. C。have a great affection for sth意为“对……钟爱，对……有深挚的感情”。
23. D。本题考查交际用语。With pleasure是愿意帮助别人时使用；help yourself
是让别人自便，通常是让别人随意拿、随意吃；never mind用于道歉；please oneself是“自便”的意思。
24. A。be separated from意为“与……分开”；be divided into意为“把（整体）
分成（部分）”。
25. C。care about意为“喜欢，对……感兴趣”。句意为：Shaw是一个对钱和名
誉不感兴趣的人。take care of “照顾，照料”，tend to“倾向于”，look ahead “向前看，为将来打算”，三者的意义与语境不符。
26. D。考查时态。从答语中的时间状语all day long，可以判断应用现在完成进
行时。
27. B。in spite of介词短语，意为“尽管”，相当于despite；even if“尽管，虽然”，
常引导句子，in case of“以防，万一”，意义与语境不符。
28. A。keep sb / sth doing让某人/ 某物一直处于某种状态。句意为：为了晚上
呆在森林中的安全，我们应一直让火燃烧着。
29. C。now and then相当于sometimes，意为“有时，偶尔”，again and again和
time and time都意为“一次又一次地，一再”，since then意为“自从那时”。
30. A。表示对过去发生的情况的推测，应该用may / might have done结构。should
have done意为“本应该做某事而没做”，must have been doing表示对过去某段时间内一直在进行的动作的肯定推测。
31. B。as a matter of fact 是插入语，前面已出现be的形式，所以排除A、C两
项。be aware of后跟名词或代词，be aware that后要跟句子。故选B。
32. C。对现在情况否定的推测应用can’t + 动词原形；当主句的时态是一般过去
式时，从句的时态要用过去的某一种时态，所以第二个空应用过去将来时。
故选C。
33. D。句意为：应当贴一张新的布告来禁止多余的参观者进入。keep sb out意为
“让某人呆在外面”。
34. A。with relief意为“放心地，松一口气地”。
35. D。根据句意“我一直想知道Anne是怎样取得这么大的成就的。”可知应选
how。
36. C。文章的中心是阐述抓捕本·拉登对布什政府的重要性。文章开头用电脑游
戏作为比喻，因此应选thought“想法，看法”，而mind意为“思考能力，智慧”。
37. B。前文的worrying和后文的election说明布什在积极准备大选。prepare for
意为“为……做准备”；而wait for “等待”，search for“查找”，look for“寻找”，三者的意义与语境不符。
38. A。out of one’s reach某人够不到的地方，不在……的掌控下。
39. A。根据上下文判断搜寻本·拉登从“9.11”事件后一直在进行着。hunt在此处用作名词。
40. D。since 自从，强调动作的持续性。
41. C。前面的has been going on说明“进展（progress）”是缓慢的。
42. B。民主党参议员John Kerry是挑战布什来参加11月份的总统大选，而且前
文也提到了election。
43. B。通过上下文可以判断：在大选前能抓住本·拉登，布什将会获得明显的优势。
44. D。解释同43。gain an advantage获得优势。
45. C。美国公众对布什政府发动的伊拉克战争的支持率在下降。support用作名
词，后常跟介词for / of，表示“对……的支持”。
46. A。根据常识判断美国政府对伊拉克发动战争是因为美国政府认为伊拉克藏
有大规模杀伤性武器，即banned weapons（禁止使用的武器）。
47. D。rose与前文的has been falling表达的意义相反，所以要用but转折。
48. A。根据常识判断萨达姆是伊拉克前总统。former以前的。
49. B。随着萨达姆的被捕，布什政府的人气又在上升，因此如果本·拉登能被抓
住，那将会对布什政府多么重要。此处只是一种“假设”，因此用if。
50. C。现在进行的民意测验（48%的选民投Bush的票，46%的选民投Kerry的票）“表明（suggest）”大选是“实力相差无几的（close）”。
51. A。解释同50题。
52. B。数千名美国士兵从伊拉克被调到阿富汗，目的就是想要“抓住（seize）”
恐怖分子及其领导人。
53. D。此句中含有短语make efforts to do sth“努力做某事”，固定搭配。
54. D。应当是soldiers频繁地巡逻阿富汗、巴基斯坦边界的村庄。
55. A。与前文的hunt呼应，美国士兵仍然是在“搜寻（search for）”本·拉登。
56. C。细节理解题。根据第一段中的“In the 1920s, archaeologists discovered some
prehistoric human bones there which changed people’s view of China’s history.”
可知答案。
57. C。细节理解题。根据第三段中的“… they used fire for cooking food and also for
light, warmth, and protection from wild animals.”可知没有用火制造工具。58. D。推断理解题。根据第三段中的内容可知A、B、C三项都正确，根据最后
一段周口店遗址的破坏可以确定没有吸引到资金。
59. D。主旨大意题。根据文章可知A项不是事实；B项是周口店遗址的作用而
不是本段的主要意思；C项只是本段所叙述的一个事实而不是本段的大意。
本段在开头叙述完周口店对于考古的意义之后详细叙述周口店现在所处的糟糕状况，因此D项才是该段的大意。
60. A。根据第三段的最后两句：对北京人遗址的发掘工作由于日本的侵略曾一
度终止，新中国成立后，发掘工作又重新开始。由此可以推知对北京人遗址的发掘工作进展的不顺利。B项是事实而不是推论，C、D两项是错误的。故选A。
61. C。推理判断题。第一段中讲12岁没上过学的男孩了解很多关于牲畜的事，
就说明生活本身就是一种教育。
62. D。推断作者的意图。每天我们都在体验不同的事物，这就是教育。因此，
教育无处不在。
63. D。细节理解题。从第三段中的“You find this out by doing these things.”可知答案。
64. A。从第二段中的“We start learning on the day we were born, not on the first day
we go to school.”可知答案。
65. B。细节理解题。根据最后一段中的“At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.”可知答案。
66. C。细节理解题。从第一段中的“This arises from the different ways in which they
consider things, persons and events, and the resulting effects upon their minds.”可知答案。
67. B。sour原意是“变酸”的意思，从短语所在的语境可以猜出短语的意义是
“使别人不高兴”。
68. C。作者用大量笔墨表达了这个观点。并且在第二、三段中更有直接的叙述。
69. A。细节理解题。最后一段中有这样一句“If they don’t，it will be good for others to avoid any contact with them”，由此可知答案为A。
70. C。通读全文可知，作者在描述了这类人后，提出了建议，从而最终归结到写作的目的。
71. B。从第二段中的“The blog is one form of communication that has increased in
popularity.”和第三段中的“Blogs also connect people with other people who have the same interests.”可以得知答案。
72. C。从文章第四、第六段的内容可以看出，两个网站的共同点是都很受年轻人欢迎。
73. A。从第六段段中的“Three young men created YouTube almost two years ago as
a personal video sharing service.”可知答案。
74. B。文章最后一段解释了SecondLife是一个怎样的网站。
75. D。从全文看出，文章介绍了几个著名的网站，都是人们越来越喜欢的沟通
方式。
