上海市九年级英语状语从句专项练习
一、考点分析
根据考纲要求，上海市中考英语对于杨盼盼电影复合句的考查重点为宾语从句和状语从句，定语从句在初中范围内只需做简单了解。状语从句的考题集中在单选和改写句子两大题，常考时间、让步、地点、条件、目的等状语从句，这些从句仍是今后中考热点，应作充分准备。同时对方式状语从句也应引起重视。
二、专题详解
二、从句的位置：由从属连词引导的部分为从句。当状语从句在主句之前时，要用逗号与主句隔开；当状语从句在主句末尾，一般不用符号间隔。
三、分类讲解：
△ 时间状语从句梅畔雪村无处寻 (打一字)
章子怡汪峰结婚（一）表示时间的状语从句可由when， as， while， whenever， after， before， till(until)， since，once，as soon as 等引导。
e.g. When I came into the office, the teachers were having a meeting.
He started as soon as he received the news.
Once you see him, you will never forget him.
陕西营养师培训 e.g. I’ll ring you up as soon as I get to New York.
I will tell him everything when he comes back.
He won’t believe it until he sees it with his own eyes.
（三）易错辨析：
比较while, when, as
1）as, when 引导短暂性动作的动词。
Just as / Just when / When I stopped my car, a man came up to me. 蜂鸟起诉邓紫棋
大数据专业是学什么 2）当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或 while。
When you have finished your work, you may have a rest.
3）从句表示“随时间推移”连词能用as，不用when 或while。
As the day went on, the weather got worse.
4）When: 表示时间点，还可以表原因“既然”；还可以翻译成“突然”
5）While: 表示时间段，还可以用来表示对比“而”；while位于句首“尽管”引导让步状语从句。
until 和not …until的区别
1）until句子翻译成“动作直到…时候才结束”；与延续性动词连用
I slept until 12 o’clock.
2）not…until句子要翻译成“动作直到…时候才开始”；与非延续性动词连用
We didn’t get down to working until Mr Zhang came in.
△ 地点状语从句
（一）表示主句动作发生的地点，引导地点状语从句的连词是where 和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
Where there is will, there is way. 有志者，事竟成。
△ 原因状语从句
（一）表示原因或理由的，引导原因状语从句的连词是because，since，as，now that（既然）等.
e.g. He is disappointed because he didn't get the position.
As it is raining, I will not go out.
Now that you mention it, I do remember.
（二）比较：because, since, as和for
1）语气强弱：because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since.
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2）由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
3）because和so不能同用在一个句子里。
△ 结果状语从句
（一）表示事态结果的从句，通常主句是原因，从句是结果。由so that（从句谓语一般没有情态动词）， so …… that， such …… that等引导。
e.g. She was ill, so that she didn't attend the meeting.
He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
（二）比较：so和 such 其规律由so与such的不同词性决定。
1）such 是形容词，修饰名词或名词词组
2）so 是副词，修饰形容词或副词；与表示数量的形容词many, few, much, little连用，形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
（ so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能用such搭配。）
3）常考查改写句子：
It was such wonderful film that all of us wanted to see it again.
= The film was so wonderful that all of us wanted to see it again.
It is such an important match that nobody wants to miss it.
= The match is so important that nobody wants to miss it.
△ 条件状语从句
（一）表示假定主句某事发生的条件，主要的引导连词有if， unless， so / as long as， on condition that， so / as far as， if only (= if )。注意：条件从句中的if 不能用whether替换。
（二）在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态（主将从现，但主句也可祈使句或者情态动词句型，从句依旧是一般现在时）。例如:
I’ll help you with your English if am free tomorrow.
He won’t be late unless he is ill.
（三）“祈使句 and(or) + 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如:
Hurry up, or you’ll be late. = If you don’t hurry up, you’ll be late.
Study hard and you will pass the exam. = If you study hard, you will pass the exam.
△ 方式状语从句
（一）强调做主句事情的依据或方式，常由as，as if (though)， the way， rather than等引导。
e.g. You must do the exercise as I show you.
He acted as if nothing had happened.
△ 让步状语从句
（一）表示某种与主句相反的条件或情况，但从句所表示的这些不利因素并不能阻止主句动作的发生，连接词although, though, as, even if (though), whatever, whether…or, no matter who (when, what, …) 等。
