【題目】閱讀理解。

Every spring Beijing is choked by huge sandstorms.The sky turns a strange and frightening yellow colour as clouds of sand sweep down from the deserts of Mongolia and north-western China.Strong winds blow up the dust and cover everything in sight—in 2006,a storm dumped 330,000 tonnes of dust on Beijing in one night.

The number of sandstorms has grown alarmingly over the years as the deserts have expanded.This is partly man-made and partly because of climate(氣候).Many grasslands have been overgrazed(過度放牧)by sheep and goats,or ploughed up,leaving the soil dangerously exposed.Too much water has been taken out of rivers,and the situation is made worse by increasingly long-lasting droughts that have affected the northern half of China as the climate grows warmer and drier.The result is probably the worst loss of rich land to deserts in the world and a dust bowl of extremely large proportions.The nearest sand dunes to Beijing are now only 70 km away and drifting closer each year.At this rate,the desert will reach the city by 2040,and Beijing could become the world’s first modern city to disappear under sand.To hold back the deserts,a huge programme of forest planting called the Great Green Wall has been under way for over 30 years.The barrier(隔離帶)is planned to be 4,500 km long when completed in several decades(十年),but the drought is having a very bad effect on the trees and the deserts carry on growing.

【1】All the following are the reasons for the expansion of the deserts EXCEPT .

A.the soil of the grasslands is exposed

B.too much span>water in rivers has been used

C.it doesn’t rain for a long time

D.the climate in northern China is colder and drier

【2】At what speed do the nearest sand dunes move towards Beijing according to the passage?

A.More than 15 km a year.

B.More than 2 km a month.

C.More than 2 km a year.

D.More than 15 km a month.

【3】What is the purpose of the huge programme“the Great Green Wall”?

A.To protect the Great Wall.

B.To plant as many trees as possible along the Great Wall.

C.To stop the deserts from moving towards Beijing.

D.To plant as many trees as possible in Beijing.

【4】In which section can this passage most likely be found in a newspaper?

A.Science and technology.

B.Weather.

C.Environment.

D.Health and life.

【答案】

【1】D

【2】C

【3】C

【4】C

【解析】

試題解析:

【1】根據(jù)第二段中的“Too much water has been taken out of rivers...as the climate grows warmer and drier.”可知,氣候是在變得越來越干,越來越暖,而不是變得更寒冷。

【2】根據(jù)第二段中的“The nearest sand dunes to Beijing are now only 70 km away...”和“At this rate,the desert will reach the city by 2040...”可進行如下計算:70÷(2040-2015)≈2.8km/年。

【3】根據(jù)第二段倒數(shù)第二句可知答案是C項。

【4】文章主要講述了沙塵暴對北京的影響,并分析了其原因及應(yīng)采取相應(yīng)措施,都是因為對環(huán)境的關(guān)注而展開的,據(jù)此可推知該文章應(yīng)出現(xiàn)在報紙的環(huán)境專欄。

【題目】Letter One

Dear Editor,

After I finish my homework, I often go online and chat with my friends. Sometimes I play Internet games. But my parents hate to see me playing games on the computer. Maybe they have heard too much news about how QQ and Internet games harm children. Once I went to a net bar to play games after school. But after that I told my parents that I was playing basketball at school. I said so because I didn’t want to make them unhappy. I feel bad about it. However, I need to rest for a while by playing computer games after studying for a long time. I really want my parents to understand that. Do foreign parents do the same to their children? Please help me.

Li Ping, Nantong

Letter Two

Dear Li Ping,

I think it’s not strange for parents to keep their children away from anything bad. Foreign parents will do the same as your parents! They may not let their children watch TV for too long a time, or like your parents, they don’t want their children to play computer games.

Talk to your parents and be honest to them, I think. Tell them what you are doing and why you are doing so to make them understand you. It’s never good to do things behind your parents’ backs. They aren’t fools as you think sometimes! Our parents seem to know what is the best for us. Remember: to be honest is the best way.

Good luck,

Rebecca

【1】From the passage we can learn that Li Ping often ________.

A．talks to his friends on the Internet

A. You must do everything in front of your parents

B. You must always listen to your parents carefully

C. You should tell your parents what you do before or after doing it

D. You should not do anything to make your parents worry about you

【4】The editor thinks _____.

【題目】The meaning of the word “Volunteer” may be a little different in different countries, but it usually means “one who offers his or her services.” There are many different ways in which people can volunteer, such as taking care of sick people, working in homes for homeless children, and picking up garbage from beaches and parks. Volunteers may work within their own countries or in other countries. They are often people with a strong wish to help those who are less fortunate than themselves. Volunteers don’t expect any kind of pay.

At the root of volunteering is the idea that one person may have the ability to offer services that can help other people. Tracy, a good friend of mine, however, recently came back from India with a new idea of what being a volunteer means. She worked for two and a half weeks in one of Mother Teresa’s homes in Calcutta. The following is her story.

“I first heard about Mother Teresa in my high school, we watched a video about her work in India and all over the world. I was so moved by her spirit to help others and her endless love for every human being that after I graduated from high school, I too wanted to try her kind of work. So with two friends I flew to Calcutta for a few weeks.”

“I was asked to work in a home for sick people. I helped wash clothes and sheets, and pass out lunch. I also fed the people who were too weak to feed themselves and tried to cheer them up. I felt it was better to share with them than to think that I have helped them. To be honest, I don’t think I was helping very much. It was then that I realized that I had not really come to help, but to learn about and experience another culture that helped improve my own understanding of life and the world.”

【1】According to the passage, a volunteer refers to a person who ________

A．is willing to help those in need without pay

B．can afford to travel to different places

C．has a strong wish to be successful

D．has made a big fortune in life

【2】Tracy started her work as a volunteer __________.

A．a(chǎn)fter she met Mother Teresa

B．a(chǎn)fter she finished high school

C．when she was touring Calcutta

D．when she was working in a hospital

【3】Why did Tracy choose to be a volunteer?

A．She liked to work with Mother Teresa.

B．She had already had some experience.

C．She was asked by Mother Teresa’s example.

D．She wanted to follow Mother Teresa’s example.

【4】What is Tracy’s “new idea” (Paragraph 2) of being a volunteer?

A．Going abroad to help the sick.

B．Working in Mother Teresa’s home.

C．Doing simple things to help the poor.

D．Improving oneself through helping others.
