in case, for fear的用法辨析.doc

in case, for fear的用法In case (of) 表示“假如”“免得”“以防”“也许”，in case是连词后接句子要虚拟语气，in case of后接名词。for fear of/that 表示“由于害怕；惟恐,以免”of后接动名词,that后接从句用虚拟语气1. “提防”，“惟恐”这个意思讲，in case of 和for fear of 是同义词，但不一定能通用： in case of 只能用来引导名词，for fear of 多半引导动名词短语。例如：In case of fire, break the bottle. 如果发生火灾，请把瓶打破。I always put some money in my pocket in case of need. 我总是要在口袋里放一点钱以备需用。Put on a coat for fear of catching a cold.穿上外衣以免感冒.2. 短语in case 是个连接语，作“假如”、“万一”讲。例如：And now Hercules began to consider what he should do, in case Atlas should be drowned in the sea.Youd better take an umbrella with you in case it rains.3. 同if不一样，用作连词引导条件句时，in case这个短语通常用于陈述句，不用虚拟语气，而且意思也不一样。例如：In case I ask for leave, will she agree? 如果我请假，她会答应吗？If I were to ask for leave, would he agree? 如果我请假，他会答应吗？4. 即使主句是将来时态，由in case 引导的从句，仍然使用现在时态。例如：In case the weather is fine tomorrow, we shall hold a meeting. 如果明天天气好的话，我们将召开一次会议。Henry will resign in case you drive him too hard. 如果你欺人太甚的话，亨利就会辞职不干。5. 作“以防”来讲，in case相当于for fear that, 并可以通用。例如： I wrote it down in case/ for fear that I should forget it. 我已把它抄下了，免得忘记。I must stay at home this morning in case/for fear that he comes to see me. 我今天上午必须呆在家里，恐怕他会来看我。He worked hard for fear that he might be fired by the boss.他拼命地干活惟恐被老板解雇。He walked fast for fear that he should be late.他快走,以免迟到。He told us to keep quiet for fear that we might disturb others.他让我们保持安静,以免打扰别人。The weather in London is so changable that people always bring their umbrella with them for fear of rain.伦敦的天气很多变,人们总是要随身带着雨伞以防下雨。辨析 in case, for fear thatIn case of rain ,they won't go .假使下雨,他们就不去了.Take an umbrella with you for fear of rain .带上一把伞,以免下雨.in case 指“假如某种情况出现,我们要”,for fear指“我们要以免某种情况出现”,前者强调主语的能动性.2, 性能主前”情某 用的 我( ”要 ,出种假假 “雨免得把上 以 也 ， 了们连,下后 '子 语 ， 雨雨雨带名是词总,很 人扰免静保他 到迟,他 雇雇恐活拼 。会恐家须午. 忘，下已. 示 于 ：用惟可 , 当 相 动”名“作 不 就亨 " 从 拟.语 : " 0 - 0 0 _ 0= % % =/ ./ ，太欺如 。会召我的天天. 例时用然从引 由时是主. 吗，我果 答她我 , 例一思且，虚句惟陈恐通个 思件引作 样 如语词动多 名来能 通一但同是 和 , 如例”万如作语个 冒免外. 需钱放口要 我 打瓶火 发.
