Fill ineach blank with the word or phrase that best fits the context.Children’s independent access to their local streets may be important for their own personal, mental and psychological development. Allowing them to get to know their own neighborhood and community gives them a ‘sense of _____41____’. This depends on ‘___42___ exploration’, which is not provided for when children are passengers in cars. (Such children may ___43____ more, but they learn less.) Not only is it important that children be able to get to local play areas by themselves, but walking and cycling journeys to school and to other destinations provide ___44___ play activities in themselves.The reduction in children’s freedom may also contribute to a weakening of the sense of local ____45____ . As fewer children and adults use the streets as pedestrians (行人), these streets become less sociable places. There is less opportunity for children and adults to have the spontaneous（自然的）___46____that help to have a feeling of community.

A. love B. gain C. symbol D. loss53. A. However B. Therefore C. Furthermore D. Otherwise54. A. generally B. roughly C. carelessly D. regularly55. A. playgrounds B. streets C. sport D. communitySection BDirections: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)Margaret, married with two small children, has been working for the last seven years as a night cleaner, cleaning offices in a big building.She trained as a nurse, but had to give it up when her elder child became seriously ill. “I would have liked to go back to it, but the shifts are all wrong for me, as I have to be home to get the children up and off to school.”So she works as a cleaner instead, from 9 p.m. till 6 a.m. five nights a week for just ￡90, before tax and insurance. “It’s better than it was last year, but I still think that people who work ‘unsocial hours’ should get a bit extra.”The hours she’s chosen to work meant that she sees plenty of the children, but very little of her husband. However, she doesn’t think that puts any pressure on their relationship.Her work isn’t physically very hard, but it’s not exactly pleasant, either. “I do get angry with people who leave their offices like a place for raising pigs. If they realized people like me have to do it, perhaps they’d be a bit more careful.”The fact that she’s working all night doesn’t worry Margaret at all. Unlike some dark buildings at night, the building where she works is fully lit, and the women work in groups of three. “Since I’ve got to be here, I try to enjoy myself——and I usually do, because of the other girls. We all have a good laugh, so the time never drags.”Another challenge Margaret has to face is the reaction of other people when she tells them what she does for a living. “They think you’re a cleaner because you don’t know how to read and write,” said Margaret. “I used to think what my parents would say if they knew what I’d been doing, but I don’t think that way any more. I don’t dislike the work though I can’t say I’m mad about it.”56. Margaret quit her job as a nurse because _______A. she wanted to earn more money to support her familyB. she had suffered a lot of mental pressureC. she needed the right time to look after her childrenD. she felt tired of taking care of patients57. Margaret gets angry with people who work in the office because _______.A. they never clean their officesB. they look down upon cleanersC. they never do their work carefullyD. they always make a mess in their offices58. When at work, Margaret feels _______.A. light-hearted because of her fellow workersB. happy because the building is fully litC. tired because of the heavy workloadD. bored because time passed slowly59. The underlined part in the last paragraph implies that Margaret’s parents would _______．A. help care for her childrenB. regret what they had saidC. show sympathy for herD. feel disappointed in her(B)We have designed all our bank cards to make your life easier.How to use your NatWest Servicecard .As a Switch card, it lets you pay for all sorts of goods and services, wherever you see the Switch logo.

The purpose of the passage is to show you how to ________.A．play your cards rightB．use your cards abroadC．draw cash with your cardsD．pay for goods with your cards( C )Against the supposition（假设）that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at whichenergy is gained or lost from the earth.64. According to the new findings, taking steps to prevent northern forest fires may _______.A．result in a warming climateB．cause the forest fires to occur more frequentlyC．lead to a longer fire seasonD．protect the forests and the environment there65. The following are all the immediate effects after a forest fire EXCEPT _________.A．large amounts of greenhouse gases enter the atmosphereB．the levels of ozone which is a type of oxygen increaseC．snow on the ground mirrors more sunlight back into spaceD．ashes from the fire fall on the ice surface and take in more radiation from the sun66. Earlier studies about northern forest fires _________.A．analyze all aspects of how northern fires influence climateB．indicate that forest fires will pollute the atmosphereC．suggest that people should take measures to protect environmentD．suggest that the fires will speed up climate warming67. From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________. A．warm the climate as the supposition goesB．allow more snow to reflect more sunlight into space and thus cool the climateC．destroy large areas of forests and pollute the far-off sea iceD．help to gain more energy rather than release more energySection CDirections: Read the following passage and choose the most suitable statement from A-F for each blank. There are two extra statements, which you do not need.Dining in China: Culture ShockBefore coming to China, I thought of Chinese food as General Tso’s chicken, egg rolls, and fortune cookies.68 In my first few weeks here, the group I was working with went out to dozens of group dinners. We were introduced to the Chinese way of dining out, and there was quite a bit of culture shock involved.For one, the community style of dining was new to me. In America, I was used to sharing an appetizer with someone sometimes and then everyone ordering their own main course. In China, many dishes are ordered and placed on a lazy Susan. The table is spun around and you grab what you like. And we’re not just talking a starter, a main, and dessert here; a Chinese dinner is a marathon of food. 69 of course, there are always some staple foods around---rice, dumplings, or noodles. Soup comes last in a Chinese dinner instead of first, and dessert usually consists of a massive fruit plate.Using chopsticks was also new to me and took quite some time to get used to. It was always embarrassing at first when I couldn’t grab something tasty from the moving table and had to wait until the next time around. After years of practice, I can now confidently snatch a peanut as it’s flying by me on a lazy Susan---practice really doesmake perfect! In the first few months, I was laughed at so many times by Chinese people while they watched me struggle with chopsticks. That probably explains why one of my favorite things to do while dining out in many Western restaurants in town is watching young, trendy Chinese people struggle with their forks and knives.I had eaten chow mein before, as well as egg fried rice and Kung Pao chicken, but there were plenty of Chinese dishes that gave me culture shock in my first few months here. 70 While Americans basically only eat chicken breasts, wings, and thighs, Chinese will also dig into the liver, heart and especially the feet. There’s an old Chinese belief that eating an animal organ will benefit your corresponding organ---eating a heart is good for your heart, and eating a brain will make you smart. You can figure out the rest yourself.Despite all of this food-related culture shock, I can honestly say that one of the best things about living here is the food and dining out. Chinese cuisine is so complex and varied that you could spend an entire lifetime here and not taste it all. 71 To be honest, now when I go home to visit I actually end up missing Chinese food more. Sometimes, culture shock is a good thing!第Ⅱ卷I. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72. 方便的话，请帮我从邮局取包裹。

We had not seen 36 for almost a month. The crops were dying. Every day, my husband 37 to get water to the fields. But 38 we saw some rain soon, we would lose everything.However, one day I learned the true lesson of 39 and witnessed the only miracle I had 40 seen before. I was cooking in the kitchen when I saw my son, Billy, 41 toward the woods. He was walking 42 with effort, trying to be as still as possible. Minutes after he disappeared into the 43 , he came running back. I went on cooking, 44 that whatever he had been doing was finished. Moments later, 45 , he was once again walking slowly toward the woods. This activity went on for an hour. Finally I couldn’t help 46 him and saw the most amazing 47 .Several large deer stood in front of him. Billy walked right up to them. I 48 screamed(尖叫) for him to get away, because a huge deer was dangerously 49 to him at that time. But the deer didn’t even move as Billy knelt dow n(跪下). I saw a tiny 50 lying on the ground, obviously suffering from 51 , lifting its head to drink the water cupped in Billy’s hands. When the water was 52 , Billy ran back to get more. It then became quite 53 to me what my son was doing.I stood there, watching my 54 boy working so hard to save another life. As my tears began to hit the ground, they were suddenly joined by other drops. I looked up at the sky. It was as if God himself was 55 with pride. The rain that day saved our farm.36.

But neither are children expected to compare with the richer if a large family, heavy responsibility(责任) or other conditions make it necessary to give a child less spending money than customary (惯例) in the neighborhood.Whatever the pocket money is, its entire use is not controlled by the parents, because a child learns to use money correctly only through dealing with it himself. If a seven-year-old child get a quarter as a week pocket money and is made to put it all in his piggy bank to save it up, he gets no idea what the real use for the money is. He gets the shiny coins and they soon disappear.
