1) 意为使（让、请）别人做某事。其中have是使役动词，意为使、让，其后接复合宾语：sth是宾语，done(是过去分词)是宾语补足语。整个结构（或称句型）所表示的动作是别人做的，不是由句子的主语完成的。如：

Last year we had the house rebuilt.去年我们把这房子翻修了一下。

Last year we rebuilt the house.去年我们将这房子翻修了一下。

注意：第一句是我们请人翻修；第二句是我们自己动手翻修。再如：

They had a picture taken with the Japanese friends.

She intended to have her daughter educated in China.

There is something wrong with the radio. I must have it repaired.

2) 同时，have sth done还表示遭遇到某事的意思。此时，主语是无意中的受害者，而不是动作的执行者。如：

She had her watch stolen.她的表给人偷了。

He had his leg injured while playing football.他在踢足球时腿受了伤。

注意：上句她的表被人偷了，而不是她叫人偷的；下句他的腿受了伤，而不是他叫人把他的腿弄伤的。

2. Older teenagers are more likely to get summer jobs or go camping with a group of friends.大点的孩子更可能找暑期工作或者和朋友一起去露营。

be likely to do很可能，有希望

II. 语法：主语从句和表语从句
