外研版英语九年级上册Module2 语法课堂：时间状语从句的连接词
语法课堂：时间状语从句的连接词状语从句不仅是初中英语学习的重点，而且也是每年中考必考的内容之一。

如：It was snowing when we got to the airport.当我们到达机场时，天正下着雪。
(不能用while) 3．as强调主句与从句表示的动作同时发生；while强调主句表示的动作持续于while所指的整个时间内；when可指主、从句所述动作同时或先后发生。
如：He sang as he went along.他边走边唱Please write while I read.我读的时候，请写下来。
When he reached home, he had a little rest.回到家后，他休息了一会儿。

1. 当主句是将来时或祈使句时，在before、after、when、till/until、as soon as等引导的从句中，用一般现在时。
如：I will call you as soon as I get to Beijing. 我一到北京，就给你打电话。
2. when引导的从句中，谓语动词可以是延续性动词，也可以是短暂性动词；while引导的从句中，谓语动词必须是延续性动词。

2024年中考英语连词重点扫描
中考英语连词重点扫描连词是虚词，起着连接词与词、短语与短语、句子与句子的作用，所以连词不能独立担任句子的成分。
一、连词分类连词包括并列连词和从属连词。
并列连词用来连接并列关系的词、词组或分句，如and，or，but，so，for，both...and，either...or，neither...nor，not only...but also等。
从属连词用来引导从句，如that，if，whether，when，till，until，after，before，since，because，though，although，so...that，so that，in order that，as soon as，as...as等。
例如：Yan Hui was so poor but he was still happy.颜回很贫穷，但是他依然很快乐。
（but 是并列连词）The teacher said that the earth is bigger than the moon.老师说地球比月球大。
（that 是从属连词，引导宾语从句）二、并列连词（一）、表示并列关系1、and（1）、and意思是“和”“而且”，用来连接对等关系的词与词、短语与短语、句子与句子。
例如：The old man opened the window and looked out of it.这位老人打开窗子朝窗外看。
（and 连接并列谓语）I went to the Summer Palace and he went to the Great Wall.我去了颐和园，他去了长城。
（and连接两个句子）注意：如果是连接三个或三个以上的单词或词组，and一般放在最后一个单词或词组前。
and在译成汉语时，不一定要翻译出“和”来。
例如：Jack, Tom and Mary are in the same class.杰克，汤姆，玛丽在同一个班级。
unless, as soon as
Grammarunless, as soon as & so ... that ...连词是一种虚词，不能充担一个句子成分，但可以起连接的作用。
unless, as soon as和so ... that ... 都是连词，均可用来引导从句。
◆unless意为“除非；如果不〞，相当于if ... not ...，用来引导条件状语从句。
如：I won’t go fishing unless it is fine tomorrow.= I won’t go fishing if it isn’t fine tomorrow.◆as soon as意为“一……就……〞，用来引导时间状语从句。
如：I will tell you as soon as Mark arrives here.提示：1. 通常情况下，在含有unless和as soon as的复合句中，如果主句用一般将来时或主句的谓语局部含有情态动词，那么unless和as soon as引导的从句常用一般现在时。
2. unless和as soon as引导的从句既可放在主句之前，也可放在主句之后，从句位于主句之前时，常用逗号将其与主句隔开。
◆so ... that ... 意为“如此……以至于……〞，用来引导结果状语从句。
其中，so 修饰形容词或副词，常见的结构有：“so+形容词 / 副词+that从句〞和“so+形容词+a / an +可数名词的单数形式+that从句〞。
如：I’m so interested in the job that I will try to get it.He is so kind a boy that we all like him.【链接】so ... that ... 结构可与too ... to ...结构， ... enoughto ... 结构进行转换，但是如果that引导的从句中的主语和主句中的主语不同，转化为too ... to ... 结构或 ... enough to ... 结构时要用for引出逻辑主语。
