一、even if=even though即使;盡管,引導(dǎo)讓步狀語(yǔ)從句。如:
He will come to the meeting on time even if/though it rains.
即使天下雨,他也會(huì)按時(shí)參加會(huì)議。
二、引導(dǎo)讓步狀語(yǔ)從句除使用連詞even if, even though外,還可使用although, though, as。相對(duì)而言 even if, even though含有假設(shè)意味或指一種可能性,尤其even if的假設(shè)意味更強(qiáng)烈。although, though, as說(shuō)明一種事實(shí)或以該從句內(nèi)容為前提。四個(gè)連詞中as引導(dǎo)讓步狀語(yǔ)從句要用倒裝結(jié)構(gòu)。如:
Even if/though they offered twice the price, I would never sell my car.即使他們出兩倍的價(jià)錢(qián),我也不會(huì)賣(mài)我的汽車(chē)。
He made the same mistake again (even) though/although the teacher had warned him. 盡管老師提醒過(guò)他,他還是犯了相同的錯(cuò)誤。
Child as Tom is, he has learned advanced maths by himself. 盡管湯姆只是個(gè)孩子,但他已自學(xué)了高等數(shù)學(xué)。
三、as if=as though通常用來(lái)引導(dǎo)方式狀語(yǔ)從句或用于連系動(dòng)詞后引導(dǎo)表語(yǔ)從句,意為“仿佛;好像”,該從句常用虛擬語(yǔ)氣。如:
He talks as if/though he had been to Beijing many times; in fact, he has never visited the city. 他談?wù)撝路鹨讶ミ^(guò)北京很多次,而實(shí)際上他從未游覽過(guò)那座城市。
