高中生百问百答：非谓语专题（1-16）

第11题-We had better have the bookcase ____(fix) to the wall.

一般解答：have sth.done

Tyger解析：一句一动，多动必分。have是动词，fix应该用分词形式，到底是to fix还是fixed呢？

have sb. do

have sth. to do

have sth. done

这些都是考点，我们结合更多例句帮助理解。

I have a bottle to drink water. 我有一个杯子喝水。

I have my son do his homework. 我让我儿子写作业。

I have my hair cut. 我剪了头发。

结合题目应该是have sth done. 

Tyger点评：只有理解分词才能灵活运用分词。

第12题-She is said ___________(work) for an international company for three years before she came here.

一般讲解：before she came here过去的过去，用完成时to have worked。

Tyger讲解：

我们先要搞清楚to work在什么情况下使用

1.She is said to work for an an international company.

to have worked在怎样的情况下使用

2.She is said to have worked for an international company for three years.

3.She is said to have worked for an international company for three years before she came here.

通过对比我们进一步加深了对完成的理解：强调时间，强调先后。

我们还可以进一步改动下原句：She had worked for an international company for three years before she came here. 

通过这道题：我们充分理解了to work和to have worked的区别，这才是关键。
