语法单选题系列6 1．It seems you need to apologize quickly ______ a good friend. A. avoiding to lose B. to avoid losing C. avoiding losing D. to avoid to lose 【答案】B 【解析】考查动词用法。首先不定式表示目的状语，avoid doing sth避免做某事；句意：似乎你需要迅速的道歉以避免失去一位好朋友。故B正确。 2． —What’s up? You look down. —I have piles of papers ______, but I type so slowly. A. to be typed B. typed C. to type D. being typed 【答案】C 【解析】考查不定式用法。当不定式动作是句子主语所做的时候，用主动形式修饰名词。当动作不是句子的主语所做的时候，要不定式的被动形式修饰前面的名词。本题type这个动作正是句子主语I所做，故使用不定式的主动形式。故C正确。句意：我有很多论文要打印。 3．I don’t think it is teachers who ______ for giving students too much pressure. A. are to blame B. are going to blame C. are to be blamed D. should blame 【答案】A 【解析】考查固定结构。Be to blame该受责备。用主动表示被动的含义。句意：我认为给学生太多的压力，老师不应该受到责备。故A正确。 |
