Section B

Directions: Complete the following passage by using the words in the box. Each word can be used only once. Note that there is one word more than you need.

You’re making a PowerPoint presentation to a group of professors, for which you have stayed overnight. Even though your knees knock together, you try really hard to pretend to be confident on the site. All of a sudden, however, your mind goes 41 , for one of the professors shoots a glance at you, and he whispers something to another professor beside him. All kinds of questions 42 your mind at the same time. Did I say something wrong? Am I making a bad impression? Such uncomfortable feelings totally 43 you.

If you once found yourself trapped in this nightmare situation, you fit the typical model of a shy person. Shy

people, as many experts define in their studies, usually fall 44 to what is simply a careless glance or a meaningless 45 . What’s more, because of their low self judgement rooted deeply in their mind, they often cannot take friendly comments like “If you are not so 46 , you’ll make a better performance.” But being shy doesn’t 47 mean being lacking in ability or competence. Rather, many shy people are capable professionals. And what distinguishes between a 48 communicator and a shy sharer is just that the latter needs to build up his self confidence.

Despite the terrible situation s shy people are usually involved in, there’s definitely hope for them. According to experts, 40 percent of the shy population can 49 overcome shyness if given enough encouragement and support.

III. Reading Comprehension

Section A

Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.

Remains of ancient civilization are places which were designed and built as a lasting tribute(致敬) to some individuals or events. By visiting these 50 monuments, you are sure to be amazed by how 51 the ancient civilization that existed centuries before you was. Some of the facilities which could be dated back hundreds of years ago are still in use today. Besides, you will also 52 at the mysterious stories behind it. The Great Wall, 53 , is probably the best-known monument of China, which consists of a network of walls and towers through which the attack warnings could be received within minutes. 54 then had enough time to prepare. Estimates of the total length of the monument 55 , depending on which sections are included and how they are measured. One of the 56 mysteries is that, although some of the wall is 57 in special radar images taken by satellites, astronauts have confirmed that the existing wall is not several thousand years old, nor is it, as many people had 58 , visible to the human eye from outer space.

Even older than the Great Wall of China is the Great Pyramid（金字塔）of Giza. Over a 20-year period, thousands of workers made the vision become 59 with numerous blocks, each weighing more than two tons. It’s still a(n) 60 to modern people how ancient men handled 61 of these giant stones in a time when cars or boats never existed some 4500 years ago. The pyramid served not only as a tomb for King Khufu, but also a place of 62 activity. The number of the God’s servants at that time showed the importance of such activities. After Khufu died, his body was carefully treated with various medicines and materials and was wrapped in order to be

63 for long. According to ancient Egyptian belief, the pyramid, where the mummy was placed, provided a place for the king to pass into the afterlife. Then his servants performed rituals(仪式) to bring 64 to the dead king’s soul, removing all the unrest and pain from his next life.

Section B

Directions:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.

(A)

The glass window shook and Matthew placed a hand roughly through the opening to lift the latch(插销) slowly. He then climbed into the room, landing on his feet with a soft step. A sudden rush of cold air swept into the room after him. Matthew trembled and he quickly tightened his clothes. Glancing down, he saw the deep cut on the back of his hand. Sighing over his rotten luck, he tore off a piece of cloth from his coat sleeve and bandaged it. With his heart beating fast, he inched his way forward, hardly able to see anything in front of him.

“Mmmm…,” came the muffled sound. Was it just his imagination? Ignoring the thought, he began to move slowly forward again. Then, without any warning, the next thing he knew was that he had kicked something soft. Matthew took out his torch. Switching it on, he found a pair of round eyes staring at him. They belonged to a little girl! Cloth in mouth, she had been bound so tightly that movement was strictly out of the question. As he was about to turn away, her tear-streaked face stopped him. Feeling sorry for the girl, Matthew used his pocket knife to cut her loose.

The girl started to cry as she believed Matthew to be the rescuer who was there to end her ordeal(折磨). She leaned on Matthew tightly. This confused him further. What was he to do? After a few seconds, Matthew spoke in a gentle voice.

“What happened, little girl?”

From her mumbled reply, Matthew could only make out that the girl had been there for two days without food and water. It seemed that her captors had totally neglected her. Almost immediately, Matthew carried the little girl back to the window from which he had entered. As he climbed out with the girl, Matthew smiled and whispered under his brea th, “I can’t believe what I’ve just done. Neither will the police.”

65. Why was Matthew trembling?

A. He had survived a cut.

B. His head ached.

A. One foot of Matthew’s was wounded when he entered the room.

(C)

With the death of congestion pricing(高峰期行车收费) which was aimed to charge drivers for driving private cars downtown to ease traffic, New York City is left with drivers still stuck in traffic and riders packed like sardines. How else can we ease traffic jams and provide decent and affordable bus and subway service?

Gov. David Paterson took the first step yesterday by thinking of identifying new ways to improve mass transportation. With the income from congestion pricing gone, the city meets with heavy burden from its proposed $29.5 billion five-year capital program. In killing congestion pricing, the city acknowledged that the program is

“severely underfunded” and that the shortfall has to be the first area of concern. Now we need other sources of funding or increases real estate and gasoline taxes that finance the authority.

The state should now conduct a detailed environmental review of all choices for reducing traffic. Many legislators who opposed congestion pricing expressed concern that the previous plan had been given truncated environmental review, where sufficient study under the State Environmental Quality Review Act was called for. There’s time now for an all-out study of all traffic-reducing choices, from restrictions on driving days based on license plate numbers to mandated car pooling（强制共乘）. Many parties of interests, however, argue that the measures, similar to the congestion pricing, make no better sense in solving the problem.

The legislature should also give New York City the tools it needs to make buses go faster. New York has the most upsetting buses in America: it takes more time to take the M15 bus from New York’s Harlem to City Hall than to travel by “Amtrak” train from New York to Philadelphia(费城). It doesn’t have to be this way. Other cities have demonstrated that buses go faster when more dedicated(专用的) bus lanes are provided, when cameras mounted on buses are used to issue tickets to keep cars out of bus lanes and when traffic signals are designed to give buses priority.

Finally, the state should allow the city to issue residential parking permits. A study showed that 45 percent of traffic in Brooklyn New York, consists of cars looking for parking spots. Residential parking permits would discourage drivers from using neighborhood streets as a parking lot, which is definitely good news to the traffic.

72. “Congestion pricing” was mainly used to ______.

A. increase fund to finance railway system

B. reduce the prices for taking public transportation

C. discourage driving private cars in New York city

D. give more attention to environmental quality review

73. The underlined word “truncated” in the passage is closest in meaning to ______.

A. incomplete

B. outlined

C. flat

D. adequate

74. The author refers to “Amtrek” in order to demonstrate that ______.

A. American railway system is very efficient

B. Traveling by trains takes less time than by bus in America

C. Bus transportation within New York city is slow

D. Public traffic service in America is of poor quality

75. According to the passage, which of the following statements is NOT TRUE?

A. The lack of financial support is an important problem the city faces.

B. All cars are forbidden to drive on particular days to help relieve traffic.

C. Fining private car drivers for taking bus lanes makes buses faster.

D. Lack of parking spots contributed to traffic jams in Brooklyn.

Section C

Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.

76.

Gamaliel Rizzo grew up in a brownstone apartment in Brooklyn and is studying to become a doctor. Still, he spent his high school years learning how to raise goats and cows and growing corns and sunflowers. He even worked on a dairy farm in the summer, all as a member of the Future Farmers of America. Although the nation has shifted ever further from its agrarian roots, the organization is flowering. Begun 83 years ago and now known simply as the FFA, it is the largest vocational student group in the country, with more than half a million members and still growing.

77.

Although farm employment accounts for less than 1 percent of all jobs in the United States, One in 12 jobs in the U.S. is agriculture-related. And during the deep economic downturn and rocky recovery, these workers have actually fared better than most. That gives the FFA a calling card as an organization that actually prepares students for potential careers. About 70 percent of its members live in rural areas, and 19 percent live in small towns. The fastest growing part, however, is in urban and suburban areas, now making up 10 percent of the membership.

Over the past years, the group has succeeded in part by expanding well beyond agricultural science while also broadening that field to include genetics, landscape gardening an d alternative fuels. Now, the group’s chapters aim to teach students leadership and job readiness as much as the finer points of cattle care or corn fertilization.

79.

Now at a time when many employers complain about the lack of basic communication and interpersonal skills among job candidates, the FFA emphasizes work on group projects and old-fashioned presentations in essays and speeches at many of its events. Even in the purely agricultural contests like the judging of crops, students defended their positions before the judges as if they were trial lawyers in court.

80.

In daily operation, FFA members must enroll in agricultural courses at school, but they also need to complete much work after school preparing for speaking and business competitions, or tending vegetable plots or animals. They also must take part in projects related to farms and other firms. The group draws many students whose parents and grandparents were members, even if they are no longer on the farm.

Section D

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.

What do you think of when you hear the word motherhood? You usually associate motherhood with warmth, selflessness, dutifulness, and tolerance. And though most women expect that motherhood will be happy and fulfilling, the reality is that motherhood had been given relatively low respect in our society. When children don’t succeed or develop problems, our society has had a tendency to turn to a single reason--- mothers. One of psychology’s most important lessons is that behavior is multiply determined. We have to admit that the long-standing images of mothers are spoiling and unprincipled. However, when child development goes wrong, mothers are not the single person to blame even though our society models them in this way.

The reality of motherhood is that although fathers have increased their family responsibilities, the main duty still falls on the mother’s shoulders. Mothers do most family work, usually thr ee to four times more than men do. Besides, the work mothers do is repetitive and routine, often involving cleaning, cooking, laundry, and straightening up. In result, it’s reported that women enjoy family life much less than men do.

Family work is included in family relations. Most women feel that family tasks are mindless but essential. They usually enjoy tending to the needs of their loved ones even if they do not find the activities enjoyable and fulfilling.

Family work is both positive and negative for women. They are unsupervised and rarely criticized. They play and control their own work. However, women’s family work is also worrisome, tiresome, repetitive, isolating and unfinished.

In sum, the role of the mother brings with it benefits as well as limitations. Father-mother cooperation and respect help the child to develop positive attitudes toward both males and females. It is much easier for working parents to deal with changing family circumstances and day-care issues together. Mothers feel less stress and have more positive attitudes toward their husbands when they are supportive partners.

(Note: Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS.)

81. Why isn’t mother the only cause of children’s problems?

82. What are the two factors that make family life less enjoyable for women?

83. Despite their personal dislike of family work, women do family work because they are willing to ______.

84. The kid learns to look on males and females positively with the help of ______.

For questions 8-10, complete the sentences with the information given in the passage. Wildfires In just seconds, a spark or even the sun’s heat alone sets off an extremely large fire. The wildfire quickly spreads, consuming the thick, dried-out plants and almost everything else in its path. What was once a forest becomes a virtual powder keg of untapped fuel. In a seemingly instantaneous burst, the wildfire overtakes thousands of acres of surrounding land , threatening the homes and lives of many in the vicinity. Fire Starters . On a hot summer day , when drought conditions peak , something as small as a spark from a train car’s wheel striking the track can ignite a raging wildfire. Sometimes, fires occur naturally, ignited by heat from the sun or a lightning strike . However, the majority of wildfires are the result of human carelessness. Common causes for wildfires include: Arson(故意)放火，纵火. Campfires Discarding lit cigarettes. Improperly burning debris Playing with matches or fireworks Prescribed fires - Everything has a temperature at which it will burst into flames. This temperature is called a material’s flash point. Woods flash point is 572 degrees Fahrenheit (300 ) . When wood is heated to this temperature, it releases hydrocarbon gases that mix with oxygen in the air, combust and create fire. There are three components needed for ignition and combustion to occur. A fire requires fuel to burn, air to supply oxygen, and a heat source to bring the fuel up to ignition temperature. Heat, oxygen and fuel form the fire triangle. Firefighters often talk about the fire triangle when they are trying to put out a blaze. The idea is that if they can take away any one of the pillars of the triangle,
