分析 为了节省时间,老师要求我们在课上做一半的练习然后剩下的留成作业.
解答 答案:A.
根据句意"老师要求我们在课上做一半的练习然后剩下的留成作业"自然是为了节省时间,所以用动词不定式表示目的状语;have sb do sth意为"让某人做某事";故选A.
点评 一般来说不定式在句中通常做目的,原因和结果状语.
1,不定式做目的状语
Mom opened the window to let some fresh air in.
2,不定式做原因状语往往要放在表示人的喜怒哀乐等情感的形容词或分词之后.这些形容词有angry,anxious,content,clever,cruel,delighted,disappointed,excited,foolish,glad,happy,pleased,pound,ready,sorry,surprised,willing,fortunate,right,wrong,foolish,luck,quick,slow等.注意不要用逗号隔开. 如 I am glad to see you.
Many people are content to live a simple life.
3,不定式作结果状语,一般表示出人意料、意想不到的结果前面常用only修饰;Only to do
we hurried to the railway station only to find the train had left.
