题目内容

【题目】---Shall we meet at the station at 8 a.m.?

---In fact we ________. The train _______ until 10 a.m..

A. mustn’t; doesn’t leave B. mustn’t; leaves

C. needn’t; won’t leave D. needn’t; will leave

【答案】C

【解析】

句意:——我们上午8点在车站见面好吗?——事实上我们不需要。火车会直到上午10点才开。考查情态动词和动词时态辨析题。needn’t不必,指没有必要;mustn’t表示“不可以”“不允许”。 until 10 a.m.是个将来的时间,句子需用一般将来时,可排除AB两个选项。not…until直到……才,固定结构,可排除D项。根据The train won’t leave until 10 a.m.,可知是“没必要早来”,故选C。

【题目】Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion. There are many people to feed. We need more and more food.

One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic (遗传的) material. Foods from plants grown in this way are called genetically modified (转基因的) foods, or GM foods.

By changing the genetic material of a plant, it is possible to make new plants. Scientists make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice will be grown, for example, which stops people becoming blind.

Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.

GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them because they are unnatural. They may feed people, then hurt them or their children later. But both rich and poor countries are interested in their uses, and they are not going to go away. In 2050, we may think differently about them.
