第11題-We had better have the bookcase ____(fix) to the wall.
一般解答：have sth.done
Tyger解析：一句一動，多動必分幸冻。have是動詞搔课，fix應(yīng)該用分詞形式熬芜，到底是to fix還是fixed呢近速？
have sb. do
have sth. to do
have sth. done
這些都是考點囤采，我們結(jié)合更多例句幫助理解悲没。
I have a bottle to drink water.?我有一個杯子喝水够傍。
I have my son do his homework.?我讓我兒子寫作業(yè)畜挥。
I have my hair cut.?我剪了頭發(fā)仔粥。
結(jié)合題目應(yīng)該是have sth done.?
Tyger點評：只有理解分詞才能靈活運用分詞。
第12題-She is said ___________(work) for an international company for three years before she came here.
一般講解：before she came here過去的過去蟹但，用完成時to have worked躯泰。
Tyger講解：
我們先要搞清楚to work在什么情況下使用
1.She is said to work for an an international company.
to have worked在怎樣的情況下使用
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.
通過對比我們進一步加深了對完成的理解：強調(diào)時間，強調(diào)先后华糖。
我們還可以進一步改動下原句：She had worked?for an international company for three years before she came here.?
通過這道題：我們充分理解了to work和to have worked的區(qū)別麦向，這才是關(guān)鍵。
