求救五道外语题付答案忘得到合理解释
1、make sb.do sth.,所以himself后应接动词原形,选A.答案错了.
2、no longer放在句首时句子要倒装,所以排除B、D.由于任何时候孩子们都不是唯一的从事爱好的人,所以应用一般现在时,表示习惯性动作,选A.
3、be in place of……是固定用法,表示“代替……”(http://www.baidu.com/s?ie=gb2312&bs=in+the+place+of&sr=&z=&cl=3&f=8&wd=in+place+of&ct=1048576).所以选A.
4、可看出:he's开头的一定是省略了关系词的定语从句,从stuck这个过去分词也可以知道:he's并不是he is的缩写,而是he has的缩写,构成完成时态.prove表示“证明”时,后面不能直接接人称,所以不能选A、B、D.而如果像楼上说的那样选C的话,那么就不符合主语the theory这个第三人称单数了.所以应该把C选项改成 to proves to.
stick to sth.意思是“坚持某物”.
5、只要记住:since是完成时态的标志词就可以了.
