1.【2016·北京】26. ________ it easier to get in touch with us, you’d better keep this card at hand. A. Made B. Make C. Making D. To make 【答案】D 考点:考查不定式作目的状语 一、不定式的作用 作主语:不定式作主语时,谓语用单数。往往用it 作形式主语,把不定式放在谓语后面。如: It took us two hours to finish the job. It is impossible for us to get there on time. It is very kind of you to help us. 注意:(1)其他系动词如look, appear等也可用于此句型。 (2)当不定式作主语的句子中又有一个不定式作表语时,不能用It is …to…的句型。试比较: It is to negate my own idea to believe him.(错) To believe him is to negate my own idea .(对) (3)It is+ adj. of / for sb. to do sth. 结构中,当不定式的逻辑主语和前面的形容词可以构成系表结构时,用of, 否则用 for. 作宾语 (1) 动词+不定式。如: He managed to escape from the fire. I find it hard to get along with him.(it 作形式宾语) 注:下列动词通常用不定式作宾语:want, try, hope, wish, need, forget, know, promise, refuse, help, decide, begin, start, learn, agree, choose, get等 |
