初中英语常用语法知识——状语从句习题(含答案解析)

一、选择题1．This my sister and those my brothers.A．is, is B．are, are C．is, are C解析：C【解析】【分析】【详解】句意：这是我姐姐，那些是我哥哥。

考查系动词辨析。

this这个，单指代词，系词需用is；those那些，复指代词，系词需用are；根据句意结构，故选C。

2．Here ______ a pair of ______. You can use them.A．are; scissors B．is; scissors C．are; scissors D．is; scissor B解析：B【解析】【详解】句意：这儿有一把剪刀。

你可以使用。

考查主谓一致及可数名词复数。

以Here开头的倒装句，主语是空后的“a pair of ___”，系动词的形式与“a pair”保持一致，用第三人称单数形式is；scissors作“剪刀”讲时只以复数形式出现，用a pair of scissors表示“一把剪刀”。

故选B。

3．______ Lucy ______ her mother know my address.A．Not; but B．Both; and C．Either; or D．Not only; but also B 解析：B【解析】【详解】句意：Lucy和她的妈妈都知道我的地址。

考查连词辨析。

Not … but … 不是……而是……；Both … and … ……和……都；Either … or … 要么……要么……；Not only … but also … 不仅……而且……。

Either … or …连接两个主语时，谓语动词用第三人称单数形式，排除C；Not … but …和Not only … but also连接两个主语时，谓语动词就近一致原则，her mother是第三人称单数，题干中know是动词原形，不符合这两个短语的用法，排除AD；只有Both … and …连接两个主语时谓语动词可用原形。

表示“与此同时”用while，引导时间状语从句。

【答案】 D2. —I wonder how much you charge for your service.—The first two are free________the third costs $30.A．while B．Until C．when D．before【解析】考查连词的用法。

根据句意，这里表示前后句之间的对比，所以用while，表示“而”。

语意是“前面两项服务是免费的，而第三项收费30美元”。

【答案】 A3. Because of the heavy traffic, it was already time for lunch break _______ she got to her office.A. sinceB. thatC. whenD. until【答案】 C4.

1.由when,as,while 引导的状语从句：1）when 引导时间状语从句，表示当···，其谓语动词可以是延续性的，也可以是非延续性的，其作用最广泛。

初中时间状语从句语法及练习

英语时间状语从句讲解与练习〔一〕when, while 和as 引导时间状语从句的用法一、when 的用法如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。

1. When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。

2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。

3. Were you writing when the teacher came in? 教师进来的时候，你在写信吗？4. Sorry, I was out when you called me. 对不起，你打来的时候我出去了。

5. He was on the point of leaving when someone knocked at the door.他正要走，这时有人敲门。

6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。

7. I had hardly[scarcely] closed my eyes when someone knocked at the door.我刚一闭上眼，就有人在敲门了。

根据以上的例句，我们可以总结出一点：when 从句的A事件，相当于另一个事件B发生的时间点。

也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，那么不用正在进展时。

因为如果用正在进展时，它表示的就是一段时间而不是一个时间点了。

根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。

这种说法也可以参照。

实际上，when 从句也可以有其它的时态，但几乎也不用进展时，因为它也只是作为一个时间参照点。

04 状语从句-中考英语总复习重点语法精讲精练(全国通用)

状语从句一、时间状语从句要点: 时间状语从句，由以下连词引导：When，while，as，after，before，as soon as，since，till /until，by the time在时间状语从句中，要注意时态一致。

一般情况下主句是将来时的时候，从句要用一般现在时(主将从现）。

1. whenMozart started writing music when he was four years old.2. whileHe visited a lot of places while he was traveling.3. asHe smiled as he stood up.as/when/while的辨析as、when、while都表示主、从句动作同时发生（均为当......的时候的意思），三者差异如下：① as 表示“一边, 一边＂的意思,强调两个动作同时进行，并表示对比① when 1. 还可以表示从句动词的动作在主句动词的动作＂之前＂或＂之后＂发生。

2. when＝and then; at that moment (正在那个时候)① while 1. 用于时间较长时（while 后常跟进行时）2. 强调两个动作同时进行，并表示对比时有时这三个连词可以互换，有时不可以。

When I had read the article, he called me.When I got to the cinema, the film had begun.She thought I was talking about her daughter, while, in fact, I was talking about my daughter. While the alien was buying a souvenir, the girl called the police.Mother was worried because little Alice was ill, especially as father was away.4. afterHe left the classroom after he had finished his homework the other day.5. beforeMr. Brown had worked in a bank for a year before he came here.6. as soon asWe began to work as soon as we got there.I will write to you as soon as I get home. 我一到家就给你写信。

高考英语语法专题汇总：状语从句(附练习及答案)状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、地点、比较、方式状语从句。

1时间状语从句引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time 等。

时间状语从句中一般用一般现在时或一般过去时。

1．when , while, as都可解释为“当```的时候”但侧重点有所不同。

1) When后既可以接短暂性动词，也可以接延续性动词，表示从句动作与主句动作同时发生。

When I arrived home , I had a little rest.2）As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”He sang as he danced.(一面```一面) You will grow wiser as you grow older.(随着)3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。

While we were working, they were having a rest.While (they were) having a discussion, they got very confused.注意：while 有对比的含义，解释为“然而”。

eg: I prefer black tee, while he likes coffee.2．until, not…until表示“直到`才”,在肯定句中主句常用延续性动词；在否定句中常用短暂性动词。

肯定句：I waited until midnight. 否定句：I did not leave until midnight. 注意点：1）not until…在句首，主句用倒装 Not until you had explained how did I manage to do it.2) It is not until…that…引导的强调句 It was not until it was dark that he came back.3．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```”I had hardly/scarcely got home when it began to rain.I had no sooner got home than it began to rain.
