in case 后從句的時(shí)態(tài) ■原則上說,若主句為現(xiàn)在時(shí)態(tài),則從句也用現(xiàn)在時(shí)態(tài);主句為過去時(shí)態(tài),從句也用過去時(shí)態(tài)。如: I always keep candles in the house in case there is a power cut. 我家里常備有蠟燭,以防斷電。 I wrote down her address in case I forgot it. 我記下了她的住址,免得忘了。 He wasn’t going to use his car in case somebody recognized it. 他不打算用自己的汽車,因?yàn)榕掠腥苏J(rèn)出他的車。 ■有時(shí)從句也可用“should+動(dòng)詞原形”這樣的虛擬語氣(不管主句為現(xiàn)在時(shí)態(tài)還是過去時(shí)態(tài))。如: I don’t let him go out in this weather in case he should catch cold. 我不讓他這種天氣出去以防他會(huì)感冒。 I’ve bought a chicken in case your friend should stay to lunch. 我買了一只雞,免得你的朋友萬一留下來吃午飯沒菜。 ■注意,當(dāng)主句為將來時(shí)態(tài)時(shí),從句謂語不能用將來時(shí)態(tài),而要用一般現(xiàn)在時(shí)表示將來意義。如: I’ll keep a seat for you in case you change your mind. 我給你留一個(gè)座位,以防你會(huì)改變主意。 |
