【易错考点回顾】条件状语从句

【易错点睛】

引导条件状语从句的连词有if（假如），as/so long as（只要），unless（除非）等。在条件状语从句中，主句与从句的谓语动词也遵循“主将从现”的原则，即如果主句是一般将来时的句子、祈使句或主句中含有情态动词，则从句用一般现在时代替一般将来时。

You will not pass the exam unless you study hard. 除非你努力学习，否则你将通不过考试。

If I have enough money, I will travel around the world. 如果我有足够多的钱，我将会环游世界。

if用法总结：

【易错考点回顾】

1. Tomorrow we’ll go to the city park _______ it is sunny.

A. as soon as

B. when

C. if

D. as

【错因分析】没有掌握住if引导时间状语从句时的用法特点，是造成错选的主要原因。【思路点拨】正确理解连词的意思和用法，再结合语境是解题的关键。

【正确答案】句意：如果明天天气晴朗的话我们就去城市公园。根据题意可知此题考查if 引导的条件状语从句，从句用一般现在时，主句用一般将来时。故选C。

2. —Shall we have the volleyball match tomorrow?

—Oh, it will be put off if it _________.

A. snows

B. is snowing

C. snowed

D. snow

【错因分析】此题考查的是if引导的条件状语的时态特点，如果没有掌握住状语从句中，主将从现这一用法特点的话，往往容易造成错选。

【思路点拨】在考查连词用法的时候，也会从时态特点这一角度考查，需明确if引导条件状语从句的时候，时态多用主讲从现，即主句为一般将来时，从句应用一般现在时。

【正确答案】本题考查条件状语从句。主句为一般将来时，从句应为一般现在时，即主将从现原则，故选A。

高考英语状语从句专项训练

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。
