2、的主语是否相同。3.假如相同，再看从句谓语是否含有be动词。4.假如上述条件均满足，则可进行状语从句的省略。5.另外，假如状语从句的主语是it，则也满足上述规律。例句点拨When the museum is completed,the museum will be open to the public next year.1.首先判断这是一个由when引导的时间状语从句 2.再做出判断主从句主语都是 the museum 3.并且发现when引导的状语从句的谓语是is 4.那么明显符合状语从句省略的四大条件那么同学们，你们能否将状语从句省略后的句子写出来呢？答案：When completed,
3、the museum will be open to the public next year.例句点拨Hell go to the seaside for his holiday if it is possible.1.首先判断这是一个由if引导的条件状语从句 2.再做出判断主从句主语是he和it 3.并且发现if引导的状语从句的谓语是is 4.那么明显符合状语从句省略的四大条件那么同学们，你们能否将状语从句省略后的句子写出来呢？答案：Hell go to the seaside for his holiday if possible.好了同学们，你们现在已经学好了同学们，你们现在已经学会了
4、状语从句省略的两种类型。会了状语从句省略的两种类型。那么，让我们小试牛刀。那么，让我们小试牛刀。1.If it is possible,he will help you out of the difficulty.2.You must attend the meeting unless it is inconvenient to you.3.As he was young,he learned how to ride a bike.4.Although he was a farmer,now he is a famous director.5.Although he is doing his
5、best in maths these days,he has still got no good marks.6.He wont go there with us unless he is invited.7.He stood up as if he were to say something.8.She looked anxious as though she was in trouble.考点解析：高考当然不会直接考察学生直接将状语从句变成省略句 考察方向一般就是在语法填空和短文改错中出现 当然，在写作这一块也许掌握基本原理，适当使用使句子升华在语法填空中，一般考察状语从句的省略是以非谓
6、语的形式进行考察：那么我们应当先判断它是状语从句的省略，再进行条件结论的反推，从而得出答案。这也就是非谓语的机理。下面我们以具体例子来说明。语法填空典例：(2015湖南)Video games can be a poor influence if _(leave)in the wrong hands.解析：这是一个条件状语从句，并且明显是一个从句没有谓语的省略句。那么反过来，就要把从句补充完整（加上主语寻找关系）。那么本题就是“videos games”与“leave”的关系。明显是被动：if video games are left in the wrong hands.答案：left同步练习：1.One Friday evening,we were packing to leave for a weekend away when_(hear)cries for help.hearinghearing2.We were swimming in the lake when _(catch)in a storm.caught3.She fell asleep while _(do)her homework.4.Id like to see you whenever _(convenience)to you.doingconvenient
