5Never do things by ________ (half).

【答案】

1to use

2cry

3wealthier

4foolish

5halves

【解析】

1句意:微信使用简单。

分析句子可知,此处结构为be+ adj+ to do。结合所给单词,故答案为to use

2句意:汤姆总是把他的小妹妹弄哭。

根据make sb do sth表示让某人做什么,所以此处缺动词原形。结合所给单词,故答案为cry

3句意:中国变得比以前更加强大和富有。

根据系动词+形容词构成系表结构,句中有become,所以此处缺形容词。结合句中有much,所以此处用形容词比较级,故答案为wealthier

4句意:你是愚蠢的,浪费你宝贵的时间。

根据it is +形容词+ of sb + to do sth 表示某人做什么是怎样的,结合后文浪费你宝贵的时间,所以是愚蠢的,故答案为foolish

5句意:做事不要半途而废。

根据句中things是复数,所以此处也应用复数,以f结尾的单词,去fves,故答案为halves

适当形式填空:

每道题后面会给一个基础词,要结合文章上下文的时态,以及所给词的词性作出相应的改变以符合题意,并且无语法等错误。

如果所给的词是名词,无非就是变成复数形式加上相应的s或者es,或者把f变成ves等。要注意有的名词是单复数同形的;

如果是动词,就要看是过去时还是现在时,过去时要变成相应的过去式,如加ed等。如果是现在时要看主语是不是三单(第三人称单数),要加相应的ses等;

如果给的是形容词,要看一下这个需要填的词是不是修饰动词或者形容词的,如果是,要把这个所给的形容词变成相应的副词,比如加ly等。还有注意有无比较级。

本题第三题考查形容词比较级。根据系动词+形容词构成系表结构,句中有become,所以此处缺形容词。结合句中有much,所以此处用形容词比较级,故答案为wealthier

【题目】 If you stay in space for a long time, will your body change? Mark Kelly and Scott Kelly from the United States will show you the answer.

Mark and Scott are twins. They are both retired(退休的)NASA(美国国家航天航空局)astronauts. From 2015 to 2016,Scott spent 340 days at the international space station, while Mark stayed on the earth. People took measures of both men before, during and after the flight. They were helping with a NASA project which studies how long-term space travel influences the human body.

The full results of the study will come out in a year or two. But scientists are sharing some findings in the journal Nature.

A change in appearance was easy to see. Scott, when he returned to the earth, was 5cm taller before. Another change was that Scott's eyesight declined after he came back. He found he couldn't see clearly. He also found that he couldn't move his legs so easily like before. Scientist found that after coming back to the earth, he took a little longer to understand things and make decisions.

There were also changes that were much harder to see. As someone grows older, his telomeres(端粒)get shorter and become less effective to stop DNA from getting damaged. But during Scott's stay in space, his telomeres got longer while Mark's kept getting shorter.
