Section B Passage One
Some mental health research has linked depression in women with lower weight in their babies during the first year of life. They studied 632 women from small villages. The women were in good physical health and in the last three months of pregnancy.
The study identified 160 of women, or one in four, as depressed. They always felt sad or tired. They had problems eating and sleeping. They felt guilty and thought about killing themselves.
The researchers compared these women with 160 others who were not depressed.Health workers then weighted and measured the babies of both groups at birth. Re-exam- inations took place at two, six and twelve months of age. The health workers also re-exam- ined the mental health of the mothers.
Babies whose mothers remained depressed grew less than the babies of the other women. The babies of the depressed mothers were also more likely to get sick. Earlier studies showed that ten to fifteen percent of pregnant women and new mothers in Western na- tions suffer from depression. Other studies in South Asia have found that depression affects almost two times as many women in developing countries.
A new program will be started to help these new mothers. In the program health work- ers will visit new mothers for up to a year. The workers offer advice about things like health and cleanliness. The health workers will also listen to the mother’s problems and suggest some easy things at first that she can do for her baby. The program will be tested for three years to see how well it succeeds. Questions 26 to 28 are based on the passage you have just heard. 26. What is said to be relevant to babies’ lower weight? 27. Which is a finding of the research?
28. What do the health workers do to help the depressed women according to the passage? Passage Two
Not many couples stay married for 50 years. Even fewer do so for 75 years. It’s al- most impossible for a couple to be married for 85 years. But that’s exactly what Henry and Maggie Thurston did.
Henry was born on a farm in Iowa in 1857. At the age of 18 he went to Chicago to attend the university. There he met Maggie who had come from Cleveland to study art. She was one year younger.
This was a true case of love at first sight. They got married in 1876, less than six months after they met. In 1877 their first son, Jack, was born. By 1885 they had five children, including their third son, Lou, who became a well-known writer. From 1900 to 1915 Henry and Maggie became grandparents thirty one times. On February 14th, 1961, they celebrated their 85th anniversary. The day they had chosen for their wedding day had become Valentine’s Day. Over one hundred newsmen came to report on the event. The couple was seen on national TV. Most amazing of all, though, was the fact that over 1,500 relatives were also present. The youngest was a three-week-old baby girl. Henry and Maggie were old. He was
104 and she was 103.
Questions 29 to 32 are based on the passage you have just heard. 29. What did Maggie study at university?
30. Which of the following is true about Lou Thurston?
31. When did Henry and Maggie celebrate their 85th wedding anniversary? 32. How old was Maggie when they celebrated their 85th wedding anniversary? Passage Three
An old expression says, “Man’s best friend is his dog.” Today, however, it seems that cats have replaced dogs as the most popular pets in American homes. Americans have more than 62 millions pet dogs. But even more cats — more than64 million — live in American homes.
Americans are increasingly serious about their cats. These concerns have made the careof cats into big business.
Each year, cat owners buy tons of food especially prepared for cats. They buy toys and other equipment. They buy jewelry and clothes for themselves with images of cats on them. Some owners even bury their dead pets in special burial grounds. Humans have loved and respected cats for centuries. Scientists have evidence that cats and people lived together as long as 8,000 years ago. The small house cat was once a highly honored animal. In ancient Egypt, for example, people who killed a cat could be punished by death.
Early in American history cats were not treated as gods, however. They probably arrived in the United States with settlers and traders from Europe. These cats worked. They killed rats and mice.
Animal experts offer several reasons why cats have become so popular as house pets. They say cats need less care than dogs. And cats do not seem to suffer as much as dogs from being alone if the owners are away.
Some research explains the reason this way: Dogs follow you around. They want you to talk to them and play with them a lot of the time. Cats like more space and more privacy. This does not mean they do not lovetheir owners. Questions 33 to 35 are based on the passage you have just heard. 33. Which of the following is not true according to the passage? 34. What made the careof cats into a big business? 35. Why do Americans prefer cats to dogs? Section C: Compound Dictation West Texas Tries Tourism
West Texas is a vast area. Much of it—(36) especially near the so-called “ Big Bend” where the Rio Grande river runs—is rugged and desolate. It is also hot and dry, and two devastating (37) droughts during the past (38) decade almost (39) ru- ined a farming and ranching industry that was a (40)struggle even in the best of times. As a result, several (41) communities have decided to (42) promote tourism to help (43) strengthen their sagging economies.
Jack Brisbin, the County Judge in Marfa, says that not too long ago, Marfa was dying. (44) Because of repeated droughts and falling crop prices, residents could no longer depend on agriculture for income. So Judge Brisin and other community leaders decided they’d try to make some money from tourism. (45) Marfa has two advantages to aid the effort. It is near Big Bend National Park which is a popular tourist destination. And, says Judge Brisin, (46) the town boasts a unique atmospher- ic phenomenon, known as “The Marfa Lights”.

Part I. Writing Sample Writing: Traveling Abroad
In recent years more and more people in China choose to travel abroad on holidays. There are some reasons for this tendency. First, with the rapid development of China’s economy, people’s income is increasing and many people can afford to spend their holidays abroad. Second, a lot of people hope to enjoy themselves and broaden their knowledge by visiting the foreign countries in person.
However, while people are traveling abroad, they may encounter some unexpected problems. For example, some tourists, esp. older ones are poor in English speaking. Others may be able to speak English, but they can’t speak other foreign languages. So it is difficult for them to get around the non-English speaking countries or the cities they are visiting by themselves. Another common problem is tourists have to wait for some time to get their visas. And sometimes people can’t adapt to the life style of the foreign countries which usually makes them frustrated.
As for me, although there are inevitably some problems when traveling abroad, an increasing number of people are still going abroad. Just remember the old saying: When in Rome, do as the Romans do.

M: Not yet. I just bought the books today. How about you?
W:
I started this afternoon. It’s great fun reading those wonderful children
stories by Doctor Brown. M: Doctor Brown? I don’t remember seeing his name on the reading list. W:
His full name is Jonathan Brown Smith. You can find this name on the
reading list.Doctor Brown is his pen name. M:
I love reading those stories as a child. It’ll be interesting to read them now
from a different point of view. I guess they’ll give me a good idea of how children think. W: Those stories are also great for classroom use. M: How’s that?
W:
Well, take a typical Doctor Brown’s book like The cat in the hat. It has a
controlled vocabulary of only two hundred words. M:
So that means the children get lots of practices using a small number of
words over and over. W:
Exactly. In fact, the cat in the hat was written mainly to show how a
controlled vo- cabulary reading could also be interesting and fun. M:
It sounds as though this course is also going to be interesting and fun. I
think I’ll get started on reading those tonight.

When the early settlers, especially the English, arrived in the New World, the difficul- ties and dangers awaiting them were totally unexpected. Had it not been for some friendly Indians, the colonists would never have survived the terrible winters. They knew nothing about planting crops, hunting animals, building houses, or making clothing from animal skins. Life in England had been much simpler, and this new life was not like what the Span- ish explorers had reported. The settlers did introduce Iron tools, guns for hunting, trained animals, and political ways to the Indians. In exchange, the settlers learned to build boats for water transportation and snowshoes for winter traveling. The Indians also taught them to make marks for oth- ers to follow, to hunt large animals and trap smaller ones, and to catch fish in the lakes and streams.
The natives also introduced to the settlers typical food such as corn and beans. Every- thing possible was done in order to make their new village resemble the homes they had left behind.
Questions 26 to 28 are based on the passage you have just heard. 26. What did the new settlers teach the Indians?
27. Which of the following was not introduced to the settlers by the Indians? 28. According to the passage, which statements is not true? Passage Two
There are thousands of colleges and universities in the United States. Nearly half of the high school graduates in America go on to college. Most go to large universities. These are state universities. Some of these universities have 40,000 or more students. There are also many small universities with only a few hundred students. Large univer- sities have many buildings, each building for a particular subject. The buildings are in a large area. This area is the university campus. Students often must go from one building to the next class in another building across campus. They may have only a few minutes between classes to go from one building to another. When students begin the university, they must take classes in many subjects. These are the required courses. English and math are usually required courses and often a history and a science course are required too. Most of the students will study mostly required courses during their first year. Lat- er, they will specialize, and takecourses in one subject.
Questions 29 to 31 are based on the passage you have just heard. 29. How many colleges and universities are there in the United States?
30. How many required courses for American university students are mentioned on the tape?
31. Which of the following statements is Not true? Passage Three
The last part of this century will be an age of exploration such as man has never known. There are eight planets, at least thirty moons, and thousands of asteroids to be explored. Their total area is about 250 times that of the earth. Spaceships will not be able to land on some of them. But that still leaves to be explored an area ten times as great as the continents of the earth.
Exploring space may seem terrifying to some people. No doubt explorers of the past were terrified by the great empty oceans that lay before them. They conquered their fears, crossed the oceans, and built the New World.
In the past when explorers set sail into the unknown, they had to say good-bye to everything they knew at home. Space explorers will not face such great loneliness. Even when they travel far beyond the sun, they will be able to send messages back.
Questions 32 to 35 are based on the passage you have just heard. 32. When does the writer think that this exploration areawill be explored? 33. How large is the total area?
34. What areas will man probably explore?
35. What will the space explorers do when they travel far beyond the sun? Section C: Compound Dictation
Directions: In this section, you will hear a passage three times. When the passage is read for the first time, you should listen carefully for its general idea. When the passage is read for the second time, you are required to fill in the blanks numbered from 36 to 43 with the exact words you have just heard. For blanks numbered from 44 to 46 you are required to fill in the missing informa- tion. For these blanks, you can either use the exact words you have just heard or write down the main points in your own words. Finally, when the passage is read for the third time, you should check what you have written.A major new study shows American children spend more time than ever - and at a (36) younger age than ever- at home watching television, listening to music and radio, using computers and playing video games. The study also (37) indicates that much of this time is spent without parental (38) supervision. Zlatica Hoke reports the new findings are causing the debate over how much (39) influence the mediaespecially violent shows and games -have on young people’s (40) behavior today.
The study, (41) sponsored by the Kaiser Family Foundation, finds that many American children today have bedrooms that are fully (42) equipped media centers. They have multiple channel televisions, CD and video players, radios, computers and other electronic gadgets. The study shows kids, aged two to eighteen; spend an (43) average of almost five and a half hours daily using electronic media for rec- reation. (44) They spend most of that time - almost two and a half hours a day - watching television. Listening to music takes the second place at 48 minutes a day. (45)Although they still read for fun- on average 44 minutes a day, a growing number of kids spend a lot of time playing computers and video games.
Concerned parents, family advocacy groups and some educators contend that the media entertainment for young people contains too much violence. (46)There- fore, many people link exposure to violent TV, computer and video programming, combined with the availability of firearms, to the rise in violent juvenile crime in the United States.

Part I. Writing Sample Writing: Dear Professor Brown, How are you recently? An Invitation Letter
I would like to write this letter to invite you to give a lecture for all the students in
our university. We sincerely hope you can come.
Our university is a non-leading comprehensive university and we offer students courses concerning science and technology, arts, law, economy, management and educa- tion. Most students in our university study very hard and a lot of them take a particular interest in English study. However, many of them find their English study is of low efficiency. It seems that they are not properly guided in the process of English learn- ing. Therefore, we wonder whether you could help them with their English by giving a lecture on English learning, especially the proper method of learning English. Also, we would like you to give them some help on how to acquire language skillsquickly and efficiently.
We really appreciate it if you can accept the invitation and we are looking forward to your reply at your earliest convenience. Best regards!
Sincerely yours, Li Ming

该短文主要讲述废纸回收问题。做题的关键在于分清词性，理解文章含义。 47. 答案E. stop。根据语法判断得知空格所在句子缺少谓语动词，即此处须填入一个动 词，所有选项中只有E和K是动词；再根据搭配v + doing, 只有stop符合，而且意思也恰当。故是正确选项。
48. 答案A. contrary。通过分析，这里应表示与流行的想法相反，所以contrary是最佳选 项。
49. 答案G. recovery。根据语法判断，空格处所填词汇是定语，修饰名词rates，所以可以 选择形容词、分词或名词。结合上下文的意思，可以确定这里指的是回收率，故选G。
50. 答案C. perfectly。同样根据语法判断，空格处所填词汇是定语，修饰good，只能选择 副词。比较C. perfectly和D. continually后，在意思上C. perfectly更恰当。
51. 答案B. recycled。这句话表示人们除了扔掉很多很好的纸张外，还有一些纸张太脏而 无法回收，还有一些项书本、杂志、文件等从来不被扔弃的纸张。做这道题的关键在于理解，同时根据and前连接的是soiled，说明所选词与soiled意义相反；而且最好是被动语态，所以B. recycled必然是正确答案。 52. 答案O. documents。可以看出这里须填名词，排除已经选用过的，待选项有H. be- lief，M. cooperation，O. document。再根据语意，不难选定O. documents。53. 答案N. weak。很明显这里是一个形容词，L. similar 和N. weak成为备选项。而在语意上可以确定答案为N. weak。
54. 答案H. belief。根据语法判断，空格处所填词汇是名词。结合36题，还剩H. belief和M. cooperation可选。空格后是同位语从句，所以只能选择H. belief。 55. 答案K. ensure。根据语法判断，空格处所填词汇必须是动词，K. ensure是仅剩且正确 的选项。
56. 答案J. converting。在instead of之后必然是v-ing, 形式上合适的选项有F. preventing，I. controlling，J. converting。三者中只有J. converting在语意上合适。 57-61 BADCD
57. 答案B。细节题。文章第一句说到大多数顾主希望雇上合适的人选，这并非意味着他 们只雇合适的人选，可以排除A选项；在第一段后两句可以得知他们事实上是拒绝不 合适的人选，所以B正确。C与D两个选项考察对于第二句的理解，C选项与原文意思 相反，D没有谈到。
58. 答案A。细节题。从第二段第二行可以看到recruiters(招聘人员) used three main selection methods to identify the right person，故选择A。
59. 答案D。细节题。此题考察对于第三段的理解。不难看出，研究证明面试不被视作可 靠的原因有两点：1，面试结果容易受到书面申请材料的影响；2，每个面试官的理解 不尽相同。因此选择D。
60. 答案C。细节推理题。通过前面的语句，可以推断这个词指评判的标准。A. model. 是 模范、榜样，B. example例子，D. method方法。
61. 答案D。细节题。在第四段第二句说到书法被一些招聘人员当作评判的一项标准 62-66 B A C C A 解析：
62. 答案B。主旨题。纵观全文可以发现第一段首先对技术下了定义，接而谈到它给人们 带来的种种好处，包括产量的增加、人们生活水平的提高，甚至还能延长人的寿命； 第二段进一步说明技术进步可延长人们寿命和提高生活质量，因此美国不惜投巨资于 科研开发；最后一段主要讲述技术的进步受人们需求所推动。选项A、C、D都过于 片面，只有B为正确选项。
63. 答案A。细节题。该题考察对于单句的理解，即第一段最后一句“technology
