1.I've decided to have go,(leaving) my fear behind.

考非谓语动词的用法
为什么用非谓语动词呢,是因为省略了主语,而这个主语就是主句的主语
也就是说前后两句的主语是一致的,这时才可以省略其中之一的主语而用非谓语动词
比如此题中,这句话还原就是前一句的主语和后一句是一样的,I've decided to have and I leave my fear behind的主语都是 I
不知你能不能读懂,都是这样的
做这种题只要找到非谓语动词的真正主语,再判断动词与真正主语间的关系,主动用doing,被动用done
1.I've decided to have go,(leaving) my fear behind.
I可以发出leave的动作,是主动关系,所以用leaving
2.(Driven) by a greater demand for this kind of software,the company has employed more engineers to produce it.
the company 不能发出Drive的动作,是被动关系,所以用Driven
3.(Reminded) not to make acall in class,Boris always turns off his cellphoneduring the day.
remind sb to do sth提醒某人做某事 被动就是 sb be reminded to do sth某人被提醒做某事
这里Boris 被提醒不要做某事,Boris与Remind之间是被动的关系,所以用 reminded
4.You can't borrow books from the school library (before) you get your student card.
在你获得学生证之前,你不能从图书馆借书
也可以用unless,until 都可以的
