帶你解析AEAS考試中特定句式的事態(tài)用法!
動(dòng)詞的時(shí)態(tài)在英語(yǔ)學(xué)習(xí)中起著舉足輕重的作用,也是AEAS考試語(yǔ)法部分的重點(diǎn).今天A加未來(lái)小編帶大家一起來(lái)針對(duì)某些特殊句式中的時(shí)態(tài)加以歸納分析,希望能夠幫助大家更好的進(jìn)行AEAS考試的學(xué)習(xí)和準(zhǔn)備。
1.“主將從現(xiàn)”原則
即若主句為一般將來(lái)時(shí),時(shí)間和條件狀語(yǔ)從句通常要用一般現(xiàn)在時(shí)表示將來(lái),而不能直接使用將來(lái)時(shí)態(tài)。如:
I’ll give her the telex when she comes.她來(lái)時(shí)把電傳交給她。
I’ll return the book as soon as I have read it.這書(shū)一看完我就送還。
He’ll have four years at university after he leaves school.他中學(xué)畢業(yè)后要上四年大學(xué)。
2.since與完成時(shí)
since引導(dǎo)時(shí)間狀語(yǔ)從句時(shí),其主句通常要用現(xiàn)在完成時(shí),有時(shí)也用現(xiàn)在完成進(jìn)行時(shí)。如:
She has had another baby since I saw her last.從上次我見(jiàn)到她以來(lái),她又生了一個(gè)孩子。
He has grown an inch since I saw him.我上次見(jiàn)到他以后他已長(zhǎng)高了一英寸。
注:當(dāng)主句為“It+be+一段時(shí)間”時(shí),則通常用一般現(xiàn)在時(shí)代替現(xiàn)在完成時(shí)。如:
It’s more than three years now since I saw her last.我們已有三年多沒(méi)見(jiàn)面了。
3.特定句式的時(shí)態(tài)
由no sooner...than,hardly[scarcely]…when引出的時(shí)間狀語(yǔ)從句,其主句通常用過(guò)去完成時(shí),從句通常用一般過(guò)去時(shí)。如:
Hardly had he arrived when she started complaining.他剛到她就抱怨起來(lái)。
No sooner had he gone to sleep than the telephone rang.他剛睡著電話鈴就響了。
We had no sooner set out than a thunderstorm broke.我們剛出發(fā)就下起一陣?yán)妆?/p>
No sooner had she agreed to marry him than she started to have terrible doubts.她剛同意嫁給他她就開(kāi)始產(chǎn)生可怕的疑慮。
