自身代詞概說(shuō)

自身代詞的用法
1.在句中作賓語(yǔ),表示動(dòng)作回到動(dòng)作執(zhí)行者的本身。如:
Please help yourself to some lea.請(qǐng)自己用茶。(作help的賓語(yǔ).
The girl is too young to look after herself.這女孩太小,還不能照顧自己。(作look after的賓語(yǔ).
He was always ready to help others; he never thought of himself他總是幫助別人,從不想到自己。(作thought of的賓語(yǔ).

虛擬語(yǔ)氣在一些特殊詞中的使用或含蓄條件句
1.wish后的賓語(yǔ)從句。
與現(xiàn)在愿望不一致,用主語(yǔ)十過(guò)去時(shí),例如:
I wi。hIwere you.
與過(guò)去愿望不一致,用主語(yǔ)+had+過(guò)去分詞,例如:Iwish I had visited the White House whenI was in the States與將來(lái)愿望不一致,用主語(yǔ)+would (could)+原形。
2.It's time句型:當(dāng)lt's tine后用that從句時(shí)應(yīng)該為主i吾+should+動(dòng)詞原形或主語(yǔ)十過(guò)去時(shí),例如:It,s time thatyou went to school.或It's time that you should go to schooL
3- If only引起的感嘆句相當(dāng)于“How I wish+賓語(yǔ)從句”。
(l)If only he could come.他要能來(lái)就好了。
(2)If only I had known the answer.我要早知道答案就好了。
4.WOuld rather,as if(though)引導(dǎo)的從句也需使用虛擬語(yǔ)氣,表示過(guò)去的情況用過(guò)去完成時(shí),表示現(xiàn)在與將來(lái)的情況用過(guò)去時(shí),例如:
(l)I'd rather you posted the letter right away.
(2)She loves the children as if they were hers.
5.含蓄虛擬條件句含蓄條件句是指句中沒(méi)有明顯的虛擬條件句,而是利用其他手段來(lái)暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導(dǎo)的條件句。常用來(lái)表示含蓄虛擬條件的手段有:
(1)介詞或介詞短語(yǔ)。如but for,but that,without,in case of, under more favorable condition等。
(2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……),for fear that(唯恐),in orderthat, on condition that, if only(要是……就好了)等。
注意:lest, for fear that和in case引起的從句中謂語(yǔ)動(dòng)詞多用should+動(dòng)詞原形,但也可以不用虛擬語(yǔ)氣,而用動(dòng)詞的陳述語(yǔ)氣形式。例如:The foreign teacher spokeslowly in case we misunderstood him這位外籍教師說(shuō)得很慢以免我們誤解。
(3)通過(guò)上下文及內(nèi)在含義,句中往往有but,otherwise, unfortunately等類似轉(zhuǎn)折詞。
without, but. but for, otherwise引起的短語(yǔ)或句子常暗含著含蓄條件。例如:
①Without you,1 would never know him
②But for your oooperation, we wouldn't have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!
