in case 后从句的时态
■原则上说,若主句为现在时态,则从句也用现在时态;主句为过去时态,从句也用过去时态。如:
I always keep candles in the house in case there is a power cut. 我家里常备有蜡烛,以防断电。
I wrote down her address in case I forgot it. 我记下了她的住址,免得忘了。
He wasn鈥檛 going to use his car in case somebody recognized it. 他不打算用自己的汽车,因为怕有人认出他的车。

I鈥檒l keep a seat for you in case you change your mind. 我给你留一个座位,以防你会改变主意。
