Question

正确形式填空
1.you must do something to prevent your house ______ (break in).
2.she decided to devote herself ______ (study) the problem of old age.
3.we should often practisw ______ (speak) english with each other.
4.it took the workmen only two hours to finish ______ (repair) my car.
5.don't forget ______ (return) this book to John when you see him.

Answer 1

1.（from ) being broken in房子与闯入之间是被动关系. 词组： prevent sth/sb from doing sth.
2.devote oneself to dong sth .某人致力于.所以应该填to studying
3.你打错了,应该是practise ,English应该大写.practise后面跟doing sth,所以应该是studying
4.finish doing sth :reapair应该用ing形式,repairing
5.forget to do sth 忘记将要做的事,forget doing sth忘记已经做过的事.根据题意,这本书还没有还给John,所以应该是to return.
我建议你看看相关的语法,这一部分是语法中的动词的固定搭配,了解了这些知识,你做这些题就不会有太大的困难了.
