27．结合材料及图，回答下列问题。（18分）
中新网12月31日电　据美国《侨报》报道，美国人口普查局29日预计，2010年1月1日，美国总人口将达3亿零840万人，比上年增加260万多人，人口增长率为0.9%。美国每8秒钟有一人出生，每12秒钟有一人死亡，每14秒钟净增一个人。很多人关注的不仅是人口的增长，还有美国人口增长对环境的影响。英国《独立报》指出：对支撑地球生命的自然体系来说，美国人口的快速增长显然不是什么好事。
(1)由图甲可以看出美国人口的增长除自然增长外还是由________________所致，这种方式的人口增长的主要原因是 。（4分）
(2)美国人口构成的变化对美国积极的影响是(　　)
A．交通通达性提高 B．文化多样化 C．劳动力数量减少 D．自由活动空间增大

28.阅读下面材料，回答问题。（18分）
近年来，“民工荒”的惊呼之声占据了媒体的大幅版面。“广东缺100万民工”，“珠三角惊呼民工短缺”。
据《南方日报》报道，广东省和4个市的劳动就业服务中心有关领导都认为广东省劳动力市场仍是供大于求，就业难与个别企业招工难并存，“有人没事干”和“有事没人干”同在；而且表示，广东省的确缺少一些高级管理人员和高级技工，但是从来不缺少普通民工。
由于劳动力市场仍然供大于求，许多民工在城里找不到合适的工作，于是纷纷打道回家。
“回流”，不是自动离弃造成的荒缺，而是被动淘汰后的黯然退出。只是在他们退出之后，高素质的、能满足现实需求的民工尚未及时补上。
由此笔者想到社会学家孙立平的“断裂社会”理论。他认为中国目前的社会是一个断裂的社会，断裂的各层处于不同的发展时代，新创造出的工作位置并不会给失业或下岗者提供多少就业的机会。就拿这次“民工荒”来说，在民工和高素质劳动者之间，又形成了断裂，这是一种“知识断裂”。“断裂”的社会，使经济状况悬殊的各阶层无法平等地享有受教育的权利。 因此导致“知识断裂”。而“知识断裂”的结果之一，就是民工“回流”，就是“民工荒”惊呼。“民工荒”是假的，“知识断裂”的残酷现实却是真真切切的。
(1)改革开放以来我国人口流动的特点是_____________________。（至少三条）（3分）
(2)造成现阶段我国人口大规模流动的主要原因是__________________
______________________________________________________________________。（3分）
(3)民工的盲目流动给城市带来的问题是____________________
_____________________________________________________________________。（4分）
(4)造成民工“回流”的原因是________________________________________
_____________________________________________________________________。（4分）
(5)你认为采取怎样的措施才能改变由“知识断裂”而导致的“民工荒”？（4分）

Going back to school is a very exciting event for my two boys. It means getting new school bags and books, and seeing friends again after the summer holiday.
My oldest son, 9-year-old Salem, asked me several times where we would go to buy a backpack, while my other son, 6-year-old Abdullah, asked what school would be like this year.
For the last three years, school was a nightmare for many children and their parents as violence increased and there were more attacks on schools and teachers. As a result, many parents prevented their children from going to school. One of six children in this country did not attend primary school in 2009. Many kids who did attend school were accompanied by a parent for the entire day to make sure nothing happened to their children.
For poor families or those with large families, back to school can be an expensive time. The government gives some help to those living in poor neighborhoods, and school bags, note books and other items(商品) are given for free.
Most of the merchants who sell notebooks and pens now sell their products out on the street instead of in stores. They sit on the ground and lay their items on the ground or they have a small table to sell their goods.
The bags cost between $10 and $20, while clothes and shoes cost between $20 and $30. I found all the things I needed for my sons and even bought something for myself. I spent about $50 on each of them, including school uniforms.
At the end of the day, we returned to our home carrying many shopping bags filled with items that made my children happy and excited to go back to school. I just hope this school year will be a peaceful one.
61．The author’s children are ________ to go to school.

Two magazines recently listed the best cities to live in. Here are two of the cities listed as “the world’s best.”
SAN JOSE, COSTA RICA The city has comfortable weather all year round (15°C to 26°C ). Housing is not very expensive in San Jose. Also, many of the city’s older neighborhoods are very beautiful and have small hotels and cafés(咖啡馆). Beautiful mountains are around the city. You can visit them easily from San Jose. So lots of people go sightseeing there every year. But air pollution is a problem in the city center.
HONG KONG, CHINA This lively city—once a small fishing village—is today an international business center. It is an interesting mixof East and West, old and new. Modern tall buildings are next to small temples (庙宇). Popular nightclubs are close to traditional teahouses. Busy people fill the streets at all hours of the day. But outside the city, there are parks for walking or relaxing. Hong Kong is famous for its wonderful native dishes. There’s also food from Europe, North America, and other parts of Asia. However, this small city has a large population. Nearly 7 million people live in Hong Kong! That’s why housing is often very expensive. Traffic and air pollution are also a problem.
66. Which of the following is not mentioned about San Jose?
A. The weather. B. The mountains. C. The air. D. The traffic.
67. What makes Hong Kong the world’s best according to this passage?
A. The lively city and the wonderful dishes. B. The beautiful mountains and the lively city.
C. The expensive housing and the food. D. The city and the people.
68. The writer thinks housing in Hong Kong is expensive because .
A. it was a small fishing village B. it is a mix of East and West

69. What do the two cities have in common?
A. They both have beautiful mountains. B. They both have a large population.
C. Air pollution is a problem in both. D. They are both crowded.
70. From the passage, we can know that .
A. San Jose and Hong Kong are the only two cities of the world’s best
B. San Jose has more natural sights than Hong Kong does
C. the weather in both cities is fine
D. Hong Kong is the more popular city of the two
PART FOUR WRITING (25 marks）
Section A?(10?marks)
Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN three words for each answer.
Develop a Healthier Lifestyle
You are what you eat. So maybe it’s time you started eating sensibly. Experts at the first Chinese Students Nutrition and Health Festival in Kunming last week singled out (挑选） several bad eating habits.
Watching television while having meals or snacks.
Doing this means you don’t pay attention to your food, forget how full you are and so overeat. It can also cause digestion(消化) diseases. One way to avoid this is only to eat in certain areas of your home.
. Replacing meals with snacks.
Many students think that eating small snacks can help them diet. But it often results
In overeating and health problems related to a lack of vegetables,carbohydrates, proteins and vitamins. Snaking only works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt.
.Having drinks rather than water.
Fizzy(有气泡的)drinks and fruit juice are usually high in calories and sugar, which can cause
weight problems. Water is important in making your brain cells and every organ in your body work properly. For your body to burn fat,it needs at least eight glasses of pure water a day. Liquids like soda(苏打水)and coffee actually take water away from your body.
.Choosing meat and certain vegetables over others.
Different foods provide different kinds of nutrition. If you don't have a balanced diet,
this can result in malnutrition(营养失调)and a weaker body.
.Eating throat tablets(润喉片)as if they were sweets.
If you eat throat tablets when you have no throat disease, they may affect the bacteria
(细菌)in your mouth and cause real throat problems.

Section B?(10?marks)
Directions: read the following passage. Answer the questions according to the information given in the passage.
In the 19the century people from all over the country came here to find gold. Many people become very rich now. They bought all the ground near the bank of the river. They dug big holes in it, trying to find more gold.
Mike Judeson was one of those who came to find gold. He bought nearly the last piece of the ground. It was a long way from the river, so no one else wanted to buy it. But Mike paid all his money for it. He worked hard month after month, but didn’t find any gold.
Then one night, just before he was going to give it up, it began to rain. It rained for several days and nights. When the rain stopped at last, Mike came out of his small wooden house to see his piece of ground. It didn’t look the same. The holes were not there any more, and a lot of small plants grew everywhere.
“Perhaps there is no gold here.” Mike said. “But this ground is rich. I can grow flowers and sell them for money. The women in this town are rich now. They have beautiful houses and they will put flowers in their houses. If I can grow good flowers here, I can make money, too.” So he did. And soon his piece of ground was covered with beautiful flowers. Later he was able to buy more fields until he owned all the ground near the river.
“I was the only man who found true gold here.” he often said. “The others took their gold out of the ground and went away. But my gold is still here.”
Why did people dig holes at the bank of the river?(no more than 6 words)

What did Mike find after the rain stopped?(no more than 2 words)

What did Mike decide to do then? (no more than 5 words)

Who would mainly buy Mike’s flowers? (no more than 5 words)

Possible version:
Dear Mr. Zhang,
However, others don’t hold the same view. They think some slower students are always making trouble, such as keeping talking in class, breaking school rules, which may lead to them forming the bad habits. Besides, slower students often ask top students questions, which has a bad effect on their studies.
In my opinion, I’d like to choose to share a desk with a slower student so that we can learn from each other and make progress together.
Yours,
Li Ping
