英语时间状语从句讲解与练习(完整版)
英语时间状语从句讲解与练习英语时间状语从句讲解与练习when, while 和 as 引导时间状语从句的用法这三个词的意思很简单，都有“当……时候”的意思。
但学生经常会问三个词的区别在哪儿，特别是在做选择题的时候。
别说是学生，就我个人而言，做这样的选择题要保证百分之百的正确也是不可能的。
现根据大量的实例和个人的思考，做一点小结，供大家参考。
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 老师进来的时候，你在写信吗？4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。
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，则不用正在进行时。
比较、让步、地点状语从句讲解和练习(答案)(可编辑修改word版)
比较状语从句通常由as…as, 比较级+ than…等连词引导。
句型：1、A+ be +as + 原级+ B2、A+ be +比较级+ than + B例如：This classroom is as big as that one. This classroom is not as big as that one.This classroom is bigger than that one. This classroom is not bigger than that one. 小试牛刀：There are many league members in class 2 in Class 4.Suzhou is not (beautiful) Hangzhou.Iron is （useful）any other metal.●让步状语从句(1) 让步状语从句通常由although, though 等连词引导。
例如：Though he is young, he knows a lot.Although I am tired, I must go on working.(2) 注意体会汉语和英语某些地方的不同，在英语中的although 和but 不能同时使用，但可以与yet 连用。
例如：Although he is a foreigner ,he likes China very much.He is a foreigner, but he likes China very much.(3)in spite of +名词或动名词，表示“尽管”例如：Although I was tired, I couldn’t fall asleep.. 尽管很累，但是我睡不着。
=In spite of being tired, I couldn’t fall asleep.小试牛刀：1. Although it was raining, still worked in the fields.A. but theyB. and theyC. theyD. and yet they2. there were only five soldiers left at the front, they went on fighting.A. Because; soB. If; andC. Though; butD. Though; /3. she is very old, she can still work eight hours a day.A. Because; soB. Though; butC. As; yetD. Though; yet4. being poor, he often gives some money to the poor.A. BecauseB. ThoughC. AsD. In spite of●地点状语从句（1）地点状语从句常常由where 来引导。
高中英语状语从句专项讲解及练习（有答案）
高中英语状语从句专项讲解及练习（有答案）状语从句1、地点状语从句地点状语从句表示地点、方位，这类从句通常由where, wherever, anywhere, everywhere引导。
Where there is a will, there is a way.有志者，事竟成。
They will go where they are happy.他们想到他们觉得快乐的地方去。
We must camp where we can get water. 我们必须在能找到水的地方露营。
地点状语从句与定语从句的区别:在于分句在句中作什么成分。
作状语，则是状语从句；作定语修饰名词，则是定语从句。
where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。
如：Go back where you came from.(where引导地点状语从句）Go back to the village where you came from.(where引导定语从句，修饰village)We went home, where we had dinner. (where引导定语从句，修饰home)2、原因状语从句原因状语从句一般由because(因为)，since(既然)，now that(既然，因为)，as(由于)等连词引导。
（1）because表示直接的原因，表示原因的语气最强，常表示必然的因果关系。
回答why引起的特殊疑问句，只能用because。
Jane wore a raincoat because it was raining.因为天下雨，所以詹穿着雨衣。
He is absent today because he is ill.他今天缺课，因为他病了。
（2）since表示对方已经知晓、无须加以说明的原因或事实，语气比because稍弱。
I'll do it for you since you are busy.既然你忙，我来替你做吧。
根据英语让步状语从句讲解及练习(简化版)

让步状语从句的结构让步状语从句的结构如下所示：- 副词从句：连词 + 主语 + 谓语，例如："Although he is tired,he keeps working."- 倒装形式：连接词 + 助动词/助动词短语 + 主语 + 谓语，例如："Tired as he is, he keeps working."让步状语从句的使用方法让步状语从句用于表达与主句相反或相对的情况。
