The poor harvest caused prices ______ sharply.

问题描述:

The poor harvest caused prices ______ sharply.
A.to rise B.to raise C.rising D.raising

选A
cause 作动词时,表示“导致”
可用表达:cause sth 如cause trouble (惹麻烦)
另外
rise是不及物动词,表示数量、程度等上升
raise是及物动词,后面加名词,表示抬起
补充说明,我在牛津字典上面,查到了和题目一摸一样的句子~一定没错!难道是cause sth to do sth?差不多可以这么理解,但是cause sth to do 里面的do是用来修饰sth的,而且也可以cause sb to do的It caused him to be killed. 差不多等于 It caused his death.
