【解析】

【分析】

【详解】

句意：暑假一开始我就去英国看望我姑姑。

考查连词辨析。as soon as一……就……；since自从；unless除非，根据主句I’ll go to visit my aunt in England是一般将来时，从句the summer holidays start是一般现在时以及语境可知，一……就……符合语境，故选A。

【点睛】

As soon as意为“一……就……”引导时间状语从句，遵循“主将从现”原则。引导时间状语从句的引导词还有before、after、when、while、since等。

例如：As soon as I arrive in Beijing,I will call you.我一到北京就给你打电话。

2．A

解析：A

【解析】

【详解】

本题主要考查连词辨析，句意：尽管水很冷，但是魏青刚跳进去救别人。因此用although 引导让步状语从句；When当……时候；If如果；Because因为，故选A。

3．A

解析：A

【解析】

【详解】

句意：当我们打游戏的时候，我们总是无法意识到时间的流逝。

考查从属连词以及状语从句。while当……时，时间状语从句；although尽管，让步状语从句；unless除非，如果不，条件状语从句；if如果，条件状语从句。当我们玩游戏时候，我们意识不到时间过得很快。时间状语从句，故选A。

4．A

解析：A

【解析】

【详解】

句意：除非你设定一个目标，否则你永远也到不了任何地方。所以无论我们做什么，我们首先应该有一个目标。

考查连词。unless除非；如果不； because因为；though尽管，虽然。根据“You will never get anywhere”可知下文是unless引导的让步状语从句，此处是“除非你树立目标”，根据题意，故选A。

5．B

解析：B

【解析】句意：尽管许多人通过网络获取最新消息，但是很可能报纸不会消失。Because 因为，引导原因状语从句；Though尽管，引导让步状语从句；Since自从，引导时间状语从句；Unless除非，引导条件状语从句。根据两句话之间的逻辑关系可知应选B。

6．B

解析：B

【解析】

【详解】

考查连词辨析。after在……以后；until：直到；because因为。连词短语not…until：直到……才……；结合句意可知选B。

7．D

解析：D

【解析】

【分析】

【详解】

句意：我不喜欢坚果，因为他们太硬了。

考查动词时态。A. didn’t rain一般过去时；B. won’t rain一般将来时；C. doesn’t rain一般现在时。本句是if引导的条件状语从句，主句是一般将来时的时候，所以从句用一般现在时，故选C。

10．D

解析：D

【解析】

句意：--我们应该坐公交车去上学而不要坐小汽车。--是的，我们用的车越少，对环境的污染就越少。这里句式：the+比较级+主语+谓语，the+比较级+主语+谓语，表示“越……，就越……”。few修饰可数名词的复数，第一空修饰可数名词cars,所以应该用fewer；第二空

pollution是不可数名词，用little的比较级修饰。故选D。

11．A

解析：A

【解析】

【详解】

句意：怀特先生告诉我们，如果明天没有达成协议，电话会议将取消。本题是含有if引导的条件状语从句的复合句。在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。选项的位置在 if 引导的条件状语从句中，要用一般现在时态，B C选项是将来时态不符合题意要排除。D选项是现在完成时态不符合题意要排除。Reach an agreement达成协议固定短语搭配。agreement is reached协议做主语要用被动语态，故选A。

【点睛】

if 条件句不一般,几个要点记心间;

条件句,放在前,逗号要放句中间。

条件句表可能，主句多用将来时；

条件句表事实，主句常用现在时。

在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。如：

We can walk there if we can't find a bus.

If it rains tomorrow, we will not go to the zoo.

What will you do if you find a panda in danger.

如果 if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如： If bears are in danger, they attack people.

注意：

在 if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若 if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则。

12．A

解析：A

【解析】

【详解】

句意：—你看上去非常疲倦。你怎么了，格林先生？—我已经工作了10小时。我如此劳累，以至于我想睡觉。

16．C

解析：C

【解析】

【分析】

【详解】

句意：蒂姆和他的双胞胎兄弟一样高，他们都有180厘米高。

【点睛】

本题考查的是as…as结构的用法，as与as之间既可以用形容词也可以用副词，而且是形容词或副词的原形，其否定形式为not as/so…as，例如：He is as tall as his sister. He doesn’t run as fast as his sister.

17．B

初中英语语法——If引导的条件状语从句(讲解及练习)

条件句从句主句 真实一般现在时一般将来时 情态动词+动原祈使句 非真实 一般过去时 be动词用（were） would/could+动原初中英语――条件状语从句（讲解&练习） Ⅰ条件状语从句的定义 Ⅱ条件状语从句的引导词 1.if引导的条件状语从句：表示在某种条件下某事很可能发生。 If we pay much attention to the earth, we'll have a better world. 如果我们多关爱地球，就会拥有一个更美好的世界 If it rains tomorrow, what shall we do? 如果明天下雨，我们怎么办？ 注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去完成时。 What would happen if there were no water ? 如果没有水会怎样？ 2.unless引导的条件状语从句，unless的意思是如果不，除非。可与if...not互换。 You will fail in English unless you work hard. 你英语考试会不及格的，除非你更加努力。 3.as /so long as引导的条件状语从句：as /so long as意思是“只要” So long as you're happy,i will be happy. 只要你高兴，我就高兴。 Ⅲ条件状语从句的种类 Ⅳ条件状语从句的时态原则 用法例句 ①主句为一般将来时态，if从句用一般 现在时态（即主将从现）。We will stay at home if it rains tomorrow. 如果明天下雨，我将要呆在家。 ②主句中含有情态动词，if从句用一 般现在时态。If you finish your homework, you can go home now.如果你做完了作业，你现在可以回家了。 ③主句为祈使句，if从句用一般现在 时态。Don’t jump into the river if you feel very hot. 如果你感到很热，不要跳入河里。 ④主句为过去将来时，if从句用一般 过去时态（如果涉及到be动词， 一律都用were）。此时，表达的是和现实相反的推测，用虚拟语 气。If I were you, I wouldn’t do it like that.如果我是你，我就不会那么做的。 If you gave me some money, I would be very happy. 如果你给我一些钱，我就会很高兴的。 二、if 引导的条件状语从句 （1）“if 从句+祈使句”的句子。其实，if 作为一个连词，主句也可以是其他形式的句子。 例如：If you want to go, please let me know. (2)“祈使句 + and (or)+ 陈述句”

(完整版)初中英语语法专题(状语从句)讲解

初中英语语法专题（状语从句）讲解 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句：

Finish this so that you can start another.把这个做完，你可以开始另一个。 结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。 让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。 方式状语从句： Students do as the teachers say.学生们按照老师说的去做。 比较状语从句： The work isn't as easy as I thought.这项工作比我想象得难。 例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别： when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用 （=while）。如： When he came in, his mother was cooking. When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.

英语语法从句讲解

从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]

1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.
