賓語從句的時(shí)態(tài)問題
1）當(dāng)主句的謂語動(dòng)詞是一般現(xiàn)在時(shí)時(shí),其賓語從句的時(shí)態(tài)可以是任何適當(dāng)?shù)臅r(shí)態(tài).所以,賓語從句的時(shí)態(tài)應(yīng)根據(jù)實(shí)際情況而定.eg.
She says (that) she works from Monday to Friday.她說她從周一至周五上班.
（從句是一般現(xiàn)在時(shí)）
She says (that) she will leave a message on his desk.她說她要在他桌子上留個(gè)便條.
（從句是一般將來時(shí)）
She says (that) she has never been to Mount Emei.她說她從來沒有去過峨嵋山.
（從句是現(xiàn)在完成時(shí)）
2）當(dāng)主句的謂語動(dòng)詞的時(shí)態(tài)是一般過去時(shí)的時(shí)候,其賓語從句的時(shí)態(tài)一般要用任一適當(dāng)?shù)倪^去時(shí)態(tài).eg.
He said there were no classes yesterday afternoon.他說昨天下午沒有課.
從句是一般過去時(shí)）
He said (that) he was going to take care of the baby.他說他會(huì)去照看這個(gè)嬰兒.
（從句是過去將來時(shí)）
He said (that) they were having a meeting at that time.他說他們那時(shí)正在開會(huì).
（從句是過去進(jìn)行時(shí)）
但是當(dāng)賓語從句是表達(dá)客觀真理和規(guī)律的句子時(shí),其時(shí)態(tài)仍舊用一般現(xiàn)在時(shí).eg.
The teacher told us(that) nothing is difficult if we put our hearts into it.
老師告訴我們世上無難事,只怕有心人.
She said(that) her father is twenty-eight years older than her.
她說她父親比她大二十八歲.
He said that light travels much faster than sound.
他說光比聲音傳播得快.
He told me that I must go to school on time every day.
他告訴我我必須每天按時(shí)上學(xué).
注意：當(dāng)主句的謂語動(dòng)詞是think或believe,賓語從句要表達(dá)否定時(shí),要把從句的否定轉(zhuǎn)移到主句上.eg.
我認(rèn)為他不會(huì)幫你學(xué)英語的.
I don't think he is going to help you with your English.
不可以翻譯成：
I think he isn't going to help you with your English.
如果賓語從句有它的補(bǔ)語時(shí),賓語從句用it代替,從句后置.其句型為：主語+謂語 + it +補(bǔ)語+賓語從句.eg.
I think it necessary that we learn English grammar.
我認(rèn)為我們學(xué)習(xí)英語語法是必要的.
He thinks it a good job that he becomes a teacher.
他認(rèn)為當(dāng)老師是個(gè)很好的職業(yè).
