Have 的兩種特殊句型
have是英語中較活躍的動詞之一,它與不同的詞搭配表示不同的意思。如:have a meeting(開會),have a rest(休息),have a class(上課)等。你可知道have構成的兩種特殊句型嗎?不看不知道,一看就明了。
1.have+賓語+省略to的動詞不定式
該句型中作主語的"人或物"讓作賓語的"人或物"去做某事。此時的賓語與省略to的不定式(賓語補足語)之間有邏輯上的主謂關系。如:I would have you buy a new bike. 我想讓你買輛新自行車。We can't have the car stop. 我們無法讓汽車停下來。
2.have+賓語+過去分詞
該句型中作主語的"人或物"讓作賓語的"人或物"被……。此時的賓語與過去分詞(賓語補足語)之間有邏輯上的動賓關系。如: I'll have my hair cut tomorrow.
我明天要理發(fā)。They have just had their car repaired.他們剛找人把車修理了一下。
注意:大多數情況下,這兩種句型之間可以互換。如:
1)He had me wash the table cloth.→He had the table cloth washed.
2) The man had the bike mended.→ The man had someone mend the bike.
訓練:根據漢語意思,完成英語句子,每空一詞。
1.你應該找人建一座房子。
You should have someone_____a house. You should have a house_____.
2.現在我們請下一位演講者到前面來。 Now we'll have the next speaker_____to the front.
3.你必須讓人把這些書送到教室去。
You must have these books_____ to the classroom
Do 的四作用
動詞do在句中的作用可以概述為四句十二字:"做"實義,助動詞,替前文,強語氣。
作用一:實義do
do作實義動詞時,有do, does, did, done, doing五種形式,還有及物、不及物之分。如:
1. vt. "做;研究;整理;完成"。如:
①The old man does an hour of sport every day.
、赟he did her homework at home last night.
③Mother was doing the cooking when I reached home.
、蹾ave you done the exercises yet?
2. vi. "行動;工作;進展;足夠"。如:
、貹ate does very well in her Chinese.
、贖ow do you do?
、踂ell done!
、躎hat will do.
作用二:助動do
do作助動詞時,只有do, does, did三種形式,無詞義,限用于含行為動詞的一般現在時和一般過去時兩種時態(tài)的否定句和疑問句中。如:
①They don't have any tickets for tonight's concert.
、贙ate stayed at home last night, didn't she?
③How many books does the library have?
、躍he doesn't do the washing in the evening.
作用三:替代do
為避免動詞的重復,使語言簡練,常以do, does, did替代前文所用的行為動詞。如:
、賂om runs much faster than you do.
②-Lucy, can you get some more tea, please?
-Sure. I'll do it right away.
、-Who broke the cup?
-Mimi did.
、-I like bananas.
-So does he.
作用四:語氣do
為突出感情色彩,do常用于祈使句、強調句和倒裝句中,以加強語氣。如:
、貲o be careful.
②Don't tell a lie.
、跦e did come.
、-You often go to the park.
-So we do.
