--- Hey, Mary, your backpack looks nice. When did you buy it.

--- I ____ it for two weeks.

A. had B. bought C. have had D. have bought

 

C

【解析】

試題分析：句意：--嗨，瑪麗，你的背包很漂亮，你什么時候買的？--我買了有兩個星期了。根據(jù)句意，說明買背包這個動作是從過去到現(xiàn)在持續(xù)了兩個星期，用現(xiàn)在完成時，而且因為buy是短暫動詞，不能和一段時間連用，所以用have這個動作，選C。

Former Irish President Mary Robinson was just making a polite conversation with an Ethiopian (埃塞俄比亞的) teenager about her wedding day. The 16?year?old had already been married for a year. “She looked at me with the saddest eyes and said, ‘I had to drop out of school’，” Robinson said in a telephone interview. “That conveyed to me the reality，” said Robinson, the first woman to serve as Ireland's president and former U．N. high commissioner for human fights. “Her life, as far as she is concerned, had more or less ended.”

Robinson said keeping girls in school was one of the most important things policymakers could do to address the coming challenges of an ever-increasing population, predicted by the United Nations to reach 7 billion soon. “European countries are concerned about aging populations as is Japan, but this is much less of an issue than the huge number of people which we are going to see over the next 40 years when the population goes from 7 billion to 9 billion，” she said. “Almost all of that increase will be in poor developing countries, so that we have a very big challenge.”

Family planning experts worry in particular about the future population explosion in sub?Saharan Africa. In May, the United Nations projected the world population would reach 9.3billion in 2050 and 10.1 billion by 2100. Much of that growth will come from Africa, where the population is growing at 2.3 percent a year—more than double Asia's 1 percent growth rate. If that rate stays consistent, which is not certain, Africa's population will reach 3.6 billion by 2100 from the present 1 billion.

Joel Cohen, a professor of population studies at Rockefeller University and Columbia University in New York, said universal secondary education offered a way to reduce population in high birth?rate regions. In addition to providing information about birth control, a secondary education teaches women to reduce their own fertility (生育力), improve the health of their children and allows them to move from a mind?set of having many children, in the hopes that some will survive to improving the quality of each child's life, Cohen wrote in the journal Nature.

1.In the first paragraph, the author introduces his topic by ________.

A．explaining the author's opinions

B．giving an example

C．describing the poor education system

D．coming straight to the topic

2.What can we learn from the passage?

A．Robinson is happy after talking to the Ethiopian girl.

B．Robinson is a successful expert in population studies.

C．Robinson is worried about population growth.

D．Robinson encourages female education.

3.What is Joel Cohen's view about secondary education?

A．It provides basic knowledge of health.

B．It improves the health of children.

C．It makes people pay more attention to education.

D．It can change people's parenting ideas.

4.According to Robinson, what is one of the most important things policymakers can do to prevent the population from increasing rapidly?

A．Keeping girls in school.

B．Letting girls go away from Africa.

C．Letting young girls remain single.

D．Keeping girls in families.
