A想對 I employed someone to do something for me(我雇用了某人為我做事)這一類句子作更簡潔的表達時，可以用這種結(jié)構(gòu)：即不說 I employed someone to clean my car，而說 I had my car cleaned(我叫人擦了車子)。又如不說 I got a man to sweep my chimneys(這里got= paid/persuaded等)，而說I had my chimneys swept(我叫人通了煙囪)。

　　注意必須用have+賓語+過去分詞，否則意思就變了：

　　He had his hair cut.

　　他理了發(fā)。相當(dāng)于：

　　He employed someone to do it.

　　他雇人理發(fā)。

　　但是：

　　He had cut his hair.(過去完成時)

　　他自己理了發(fā)。(在說話之前的某個時刻他自己給自己理了發(fā))

　　have這樣用時，其否定式和疑問式的現(xiàn)在時和過去時都要用

　　do來構(gòu)成：

　　-Do you have your windows cleaned evny month?

　　-I dont have them cleaned;I clean them myself.

　　-你每月都要叫人擦窗戶嗎?

　　-我不叫別人擦，我自己擦。

　　He was talking about having central heating put in.Did he have it put in in the end?

　　他那會兒總說要找人裝暖氣。到底裝上了沒有?

　　這種結(jié)構(gòu)可以用于進行時態(tài)：

　　I cant ask you to dinner this week as I am having my house painted at the moment.

　　這一周我不能請你來吃飯了，因為現(xiàn)在我正讓人刷房子呢。

　　While I was having my hair done the police towed away my car.

　　我(讓人)做頭發(fā)時，警察把我的汽車拖走了。

　　The house is too small and he is having a room built on.

　　房子太小了，他正叫人添蓋一個房間。

　　get能夠像have一樣用于上述句中，但更口語化。句中提到完成動作的那個人的時候，也可以用get：

　　She got him to dig away the snow.

　　她讓他把雪挖走。(她雇/說服他)

　　(have與不帶to的不定式連用也能起同樣的作用，如She hadhim dig away the snow。但在英國英語中g(shù)et結(jié)構(gòu)要常用得多。)

　　B have+賓語+過去分詞結(jié)構(gòu)在口語中可以用來代替常表示意外或不幸遭遇的被動態(tài)動詞。如 His fruit was stolen before hehad a chance to pick it(他樹上的果子還沒來得及摘就被人偷掉了)可由He had his fruit stolen before he had a chance topick it來代替。Two of his teeth were knoceked out in the fight(他的兩顆牙在打架中被打掉了)可由He had two of his teethknocked out來代替。

　　在本節(jié)A中，可以看到主語是命令別人做某事的人，而在這兒，主語則是承受行為結(jié)果的人。這里主語也可以是物：

　　The houses had their roofs ripped off by the gale.

　　房子被狂風(fēng)掀掉了屋頂。

　　這里也可以用get代替have：

　　The cat got her tail singed through sitting too near the fire.

　　貓坐得太靠近爐火，尾巴上的毛被烤焦了。
