备考指导 状语从句是历年高考中考查的最多的一个考点，通常是以单项填空、完形填空的选项、语法填空、短文改错和书面表达的形式进行考查。解决状语从句类题目通常使用的方法有：看是否是考查固定句型中固定用法，是否可以运用分析句式结构与句子成分来判断，是否可以运用句子的语境和语义来判断，是否可以通过主从句的谓语动词发生的逻辑关系来判断，是否可以通过运用还原法来做出正确的判断。

二、解决状语从句的2个方法
方法1 句意翻译法
对于状语从句的解答来说，最重要的一点是能够正确地翻译句子的意思，这样就能够判断出该从句是状语从句中的哪一种，选择也就很容易了。
典例展示1 (2016·全国卷Ⅲ)Over time, ________ the population grew, people began cutting food into small pieces so it would cook more quickly.
答案 when/as
解析 此处空格处引导时间状语从句，表示“当……时候，随着”，应用when/as。
典例展示2 (2015·陕西高考)My only mistake was that I dropped some on the floor after I was packing them up.________
答案 after→when/while
解析 句意：我唯一的错误是在我打包的时候，把一些(饼干)掉在了地上。表示“当……的时候”应用when或while。故after改为when/while。
方法2 分清句子类型法
对于有些试题来说，掌握和分清一些固定的句型结构是很重要的，同时也要注意该从句与别的一些从句的区别，如地点状语从句和定语从句，结果状语从句和定语从句等。
典例展示1 He was told that it would be at least three more months ________ he could recover and return to work.
答案 before
解析 句意：他被告知至少还要三个月他才能恢复健康，回去上班。这里使用了固定句型：It will be＋一段时间＋before...的句型，“要多久才……”， since也可以和一段时间连用，但是句型是：It is/has been＋一段时间＋since...”，故填before。
典例展示2 It will be 5 or 10 years ________ it is possible for people to found a space station on the moon.
答案 before
解析 句意：大约5年或10年后，人们才有可能在月球上建立太空站。before意为“在……之前”，常用句式：It will be some time before...。

Ⅰ.阅读理解
Last week I visited my friend Pete in the new home where he lives with his wife and daughter.Pete used to spend his holidays travelling the world，visiting the pyramids in Egypt or scuba diving(潜水) in the Caribbean.Nowadays he prefers to spend his holidays and weekends making his house look more beautiful.Like hundreds of thousands of other British people，he has discovered the joy of DIY (Do It Yourself)，which means if there are any things that need fixing around the house，he will try to do the job himself.
As he showed me the new kitchen he put together by himself and the newly painted walls，I asked Pete where he got his inspiration(灵感) from.He told me that his favorite source of ideas was a DIY program on TV.
This got me thinking about the great popularity of DIY programs in the UK.Each major channel has at least one home or garden improving show and there’s even a satellite channel completely about the subject.
I guess it is not really surprising that DIY programs are so popular.Two common sayings in Britain—“an Englishman’s home is his castle” and “there’s no place like home”—show how important our houses are to us.With the present economic downturn，many people can’t afford to buy a bigger house so they are looking at how they can make their house better without spending a lot of money.DIY is the perfect choice.
But be careful! I read a report that said over 230，000 people were injured while doing home improvements in the UK in just one year，including 41，000 who fell off
ladders(梯子) and 5，800 who were seriously hurt by hammers.So I won’t be going down to the hardware store.
1．How did Pete spend his holiday in the past?
A．Visiting his friends.
B．Diving.
C．Travelling around the world.
D．Making his house beautiful.
2．Which might NOT be shown in a DIY program on TV?
A．Scuba diving.
B．A garden improving feature.
C．Home improvements.
D．Fixing things in kitchens.
3．Which is NOT the reason why DIY is popular among British people?
A．They enjoy DIY.
B．They want to make their houses better themselves.
C．They can improve their houses without spending much money.
D．They want to be on TV.
4．At the end of the article the writer wants us to remember ________．
A．not to go to the hardware store
B．to be careful not to get hurt while doing DIY
C．to keep watching DIY on TV while drinking a nice cup of tea
D．not to climb ladders or use hammers
