【答案】

1 Neither has

2 Had left

3 if had

4 What had

5 How long

【解析】

1You haven’t read the book. He hasn’t read the book, either.意思是“你没有读书,他也没有读书”可以用Neither…nor….表示两者都不;连接两个主语谓语动词采用就近原则,he是第三人称单数。谓语动词变第三人称单数has。根据题意,故填Neitherhas。

2这里是过去完成时,根据题意改为一般疑问句,要把助动词had提前,其结构是Did+主语+动词的过去分词+其他?根据题意,故填Had left 。

3根据题意是改为宾语从句,这里是一般疑问句,改为宾语从句用if引导,主语是一般过去时态,根据题意,从句用过去完成时,其结构是had done的形式。根据题意,故填ifhad。

4根据划线部分taken a shower.可知这里用what来提问,这里是过去完成时,要借助助动词had,其结构是疑问词+had+主语+动词的过去分词+其他?根据题意,故填What had

5根据划线部分for two years可知这里用How long来提问,根据题意,故填How long。

一、肯定句变否定句:

  A. 含有be动词(am/is/are)或情态动词(can/must...)的句子,直接在be动词或情态动词后加上not。

  B. 含有实义动词(大部分动词)的句子:如果句子主语是第三人称单数,在实义动词前加上doesn’t,动词还原;如果句子主语不是第三人称单数,在实义动词前加上don’t。

  肯定句变否定句时,如果肯定句中有some,要把some改为any。

  二、肯定句改为一般疑问句:

  这是过去完成时,其结构是had done的形式,变成一般疑问句要借助动词had,其结构是Had+主语+动词的过去分词+其他?

  肯定句变一般疑问句时,如果肯定句中有some要改为any,第一人称要改为第二人称。

  三、对划线部分提问:

  做题步骤:

  1. 把原句改为一般疑问句;

  2. 根据划线部分内容确定相对应的特殊疑问词并放于句首;

  3. 省略划线部分(若划线部分是动名词、动词或动词词组则不能省略,要用doingdo代替划线部分),其余部分照抄。

  若句子中有some要改为any,第一人称要改为第二人称。

  (句尾问号别掉哦~)

【题目】Today there are 7.4 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 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.
