have sth/ sb to do什么意思？

Answer 1

　　have sth/sb to do，have sb do，have sb doing和have sth done的区别如下：

1. have sb./sth. to do意思是“有……要做”，其中的have为行为动词，意思是“有”，to do是充当后置定语，修饰sb.或sth。例如：

   I have much homework to do this summer vacation.今年暑假，我有很多作业要做。

   As a reporter, he has many people to talk with every day. 作为一名记者，他每天都要和很多人交流。

2. have sb. do意思是“让某人做……”，其中的have为使役动词，意思是“使，让”，do是不带to的不定式，作宾语补足语。例如：

   His mother has him stay at home on school nights.他妈妈让他在上学日的晚上呆在家里。

   I'll have you know. 我会让你知道的。

3. have sb. doing 意思是“让某人一直做(某事)”，have为使役动词，意思是“使，让”，doing为现在分词，充当宾语补足语。例如：

   Don't have me waiting for long.别让我等久了。

4. have sth. done意思是“让某事被做，让别人做某事”，have为使役动词，意思是“使，让”，done为过去分词，作宾语补足语。例如：

   I've had my hair cut. 我理发了。

   He's having his car repaired. 他正在（让别人）修理他的车子。
