【題目】概要寫作。閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要。
A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International(PAI) did the new study. It says more than 335 million people lack enough water now. The people live in 28 countries. Most of the countries are in Africa or the Middle East.
PAI researcher Robert Engelman says by the year 2025, about 3, 000 million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters is not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera which are carried in water.
Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. And the report says lack of water would affect the ability to improve their economies. This is because new industries often need large amounts of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water for agriculture.
The report also says long--term solutions to the water problem must include controls on population growth.

【答案】A new study shows that about 30% of the world's people may suffer a shortage of water in the following ten years. Nowadays over 335 million people in 28 countries lack enough water in the years to come, while the amount of water remains the same and the population is growing faster. The shortage of water will cause health problems and international conflict. Fortunately, ways are found to settle the water problem.

【題目】In Cairo, formal education is very important. There are twelve years of formal education in Egypt, and public schools are free, though the government does not have enough money. Many families can afford to send their children to private schools. Toward the end of high school, children planning to go to college should take an exam required. The results of that exam determine which college each student will attend and also which fields of study are open to that student. Top students can attend the American University in Cairo, which teaches its course in English. Other universities in the Cairo area include Cairo University, with over 30,000 students, Ain Shams University and Al–Azhar University. Many Children do not complete school or go on to college but learn a trade or apprenticeship in business instead.

Education comes from the family—this is where children learn about social values. The family is very important in Egyptian society. Though modern families are adopting the idea of the “nuclear family” common in the West, the traditional Egyptian family unit consists of parents, grandparents, children, aunts, uncles, cousins, in-laws and all sorts of people. Even though the modern family unit tends to be smaller, families usually live close together and visit each other often.

Unlike in the West, children usually live with their parents until they get married, even through college. It is very rare that children move out and establish their independence before they get married. Usually, this only happens if the child goes abroad to save money before getting married. Many young Egyptian men work for a few years in the rich countries of the Persian Gulf, where wages are much higher than they are in Egypt, and this allows them to have a better start when they return to Egypt and get married.

【1】If Egyptian children graduate from high school, _______.

A. some of them will decide not to attend university

B. all of them will take an exam for entering collage

C. some of them want to attend university in America

D. many of them can’t afford their higher education

【2】If you are an excellent student, you will _______.

A. be sent to American universities for study

B. be admitted to Cairo University

C. take class taught in English in Cairo

D. get a high–paid job in the future

【3】Where do the Egyptian children learn about social values?

A. Egyptian society. B. The family.

C. The West. D. All sorts of people.

【4】In Egypt some young people go to the Persian Gulf because they_______.

A. need to gain rich experience there

B. want to establish their independence

C. intend to show respect for their parents

D. wish to have a better life in the future
