I dont let him climb trees in case he tears his trousers. 我不让他爬树,以免撕破裤子。
(3) 起副词作用,其意为以防万一。如:
Youd better carry some money in case. 你最好带些钱,以防万一。
The sun is shining, but Ill take an umbrella just in case. 现在是晴天,但我还是带上雨伞以防万一。
The dog was chained, but I carried a stick in case. 狗是用链条锁住的,但我带着一根棍子以防万一。
2. 注意in case 后从句的时态
(1) 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 wasnt 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。
(2) 有时从句也可用should+动词原形这样的虚拟语气(不管主句为现在时态还是过去时态)。如:
I dont let him go out in this weather in case he should catch cold. 我不让他这种天气出去以防他会感冒。
