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(jiǎn)潔的表達(dá)時(shí)，可以用這種結(jié)構(gòu)：即不說(shuō) I employed someone to clean my car，而說(shuō) I had my car cleaned（我叫人擦了車子）。又如不說(shuō) I got a man to sweep my chimneys（這里got= paid/persuaded等），而說(shuō)I had my chimneys swept（我叫人通了煙囪）。
注意必須用have+賓語(yǔ)+過(guò)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：來(lái)源：考試大
He had cut his hair．（過(guò)去完成時(shí)）
他自己理了發(fā)。（在說(shuō)話之前的某個(gè)時(shí)刻他自己給自己理了發(fā)）
have這樣用時(shí)，其否定式和疑問(wèn)式的現(xiàn)在時(shí)和過(guò)去時(shí)都要用
do來(lái)構(gòu)成：
-Do you have your windows cleaned evny month？
-I don’t 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(huì)兒總說(shuō)要找人裝暖氣。到底裝上了沒(méi)有？
這種結(jié)構(gòu)可以用于進(jìn)行時(shí)態(tài)：
I can’t ask you to dinner this week as I am having my house painted at the moment．
這一周我不能請(qǐng)你來(lái)吃飯了，因?yàn)楝F(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(shí)，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(gè)房間。
get能夠像have一樣用于上述句中，但更口語(yǔ)化。句中提到完成動(dòng)作的那個(gè)人的時(shí)候，也可以用get：
She got him to dig away the snow．
她讓他把雪挖走。（她雇/說(shuō)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(guó)英語(yǔ)中g(shù)et結(jié)構(gòu)要常用得多。）
have+賓語(yǔ)+過(guò)去分詞結(jié)構(gòu)在口語(yǔ)中可以用來(lái)代替常表示意外或不幸遭遇的被動(dòng)態(tài)動(dòng)詞。如 His fruit was stolen before hehad a chance to pick it（他樹(shù)上的果子還沒(méi)來(lái)得及摘就被人偷掉了）可由He had his fruit stolen before he had a chance topick it來(lái)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(lái)代替。
在本節(jié)中，可以看到主語(yǔ)是命令別人做某事的人，而在這兒，主語(yǔ)則是承受行為結(jié)果的人。這里主語(yǔ)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。
