问题解答:

我来补答
答案:B
in case (如果,万一)引出条件从句时,一般是指将来时间(尽管动词时态是一般现在时)或过去将来时间,而if 引出的条件从句可以指任何时间(现在,过去,将来).
1.In case I forget,please remind me about it.如果我忘了,请提醒我一下.
2.In case the house burns down,we'll get the insurance company.
如果房子被烧毁,我们将领到保险金.
看下面两个句子比较in case和if的区别:
1.I'm taking an umbrella in case it rains later on.我拿着一把伞,以防一会儿下雨.
2.I'll take an umbrella if it rains later on.要是一会儿下雨我就拿一把伞.
in case引导的从句为主句的动作提供理由:
Some cyclists carry repair outfits in case they have a puncture.
有些骑自行车的人携带修理工具,以备万一车胎被扎破.
相当于:Some cyclists carry repair outfits because they may have/because it is pos- sible they will have a puncture. 有些骑自行车的人携带修理工具,因为他们的车胎可能会被扎破.
