状语从句的常见错误及改正
状语从句的常见错误及改正状语从句是句子中用来修饰动词、形容词或副词的从句，起到说明时间、地点、原因、条件等各种状况的作用。
然而，由于状语从句结构相对复杂，容易引发语法错误。
本文将探讨状语从句中的一些常见错误，并提供相应的改正方法。
1. 无法与主句保持一致的时间关系错误示例：当我回家，他已经离开了。
改正示例：当我回家时，他已经离开了。
错误示例中，状语从句“当我回家”与主句的时间关系不一致，应改为“当我回家时”以强调时间上的联系。
2. 主句与状语从句的时态不一致错误示例：如果我知道你要来，我会去接你。
改正示例：如果我知道你要来，我就去接你。
错误示例中，主句使用了将来时态“我会去接你”，而状语从句使用了现在时态“我知道你要来”，应改为“如果我知道你要来，我就去接你”以保持时态一致。
3. 省略了从句中的连词错误示例：因为下雨，我没去跑步。
改正示例：因为下雨了，所以我没去跑步。
错误示例中，省略了状语从句中的连词“所以”，应改为“因为下雨了，所以我没去跑步”。
4. 从句中的主谓不完整错误示例：无论你去，我都。
改正示例：无论你去哪里，我都会支持你。
错误示例中，状语从句“无论你去”缺少主语和宾语，应改为“无论你去哪里”以使从句完整。
5. 从句与主句的逻辑关系混淆错误示例：因为他没学习，所以考试不及格。
改正示例：因为他没学习，所以考试不及格。
错误示例中，使用了“因为…所以…”的逻辑关系，但逻辑上状语从句应是原因，主句应是结果，应改为“因为他没学习，所以考试不及格”以保持逻辑一致。
6. 状语从句被错误地作为主语或宾语错误示例：我们去购物，害怕遇到人多的地方。
改正示例：我们去购物时，害怕遇到人多的地方。
错误示例中，状语从句“害怕遇到人多的地方”被错误地作为宾语，应改为“我们去购物时，害怕遇到人多的地方”以正确表达状语从句的作用。
7. 状语从句和主句之间缺少逗号错误示例：尽管天气很热但是他还是坚持锻炼身体。
改正示例：尽管天气很热，但是他还是坚持锻炼身体。
语法：用ing形式改写从句
一、将下列含时间状语从句的复合句改为简单句。 1. When I saw him, I smiled.
Seeing him, I smiled. /When seeing him, I smiled. 2. If you work hard, you will succeed one day.
Working hard, you will succeed one day. 3. Since she was ill, she couldn’t attend the meeting.
→Look around when crossing the street .

状语从句第Ⅰ课时【基础知识】时间状语从句一、when，while和as1. when既可引导一个持续动作，也可引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作。
如：When I lived there，I used to go to the seashore on Sundays．___________________________________________(当电影结束的时候，激动的人们不愿离去)．当when引导的时间状语从句为系表结构，而且其主语和主句的主语一致，其表语又是一个名词时，就可以用以as引导的省略句来代替when引导的从句。
如：As a young man (= When he was a young man)，he was fond of hunting．2．while引导的动作必须是持续性的。
如：Please don't talk so loud while others are working．3．从属连词as可表示从句和主句的两个动作交替进行或同时完成，可译为“一边……，(一边……)”或“随着……”。
如：He hurried home，looking behind as he went._____________________________________________（随着时间的流失，天变的越来越暖和了）。
4．when还可用作并列连词，其意义为“在那时，在这时”，相当于and at this／that time。
常用于下列句式：①Somebody was doing something when．．．；②Somebody was about todo／going to do／on the point of doing something when．．．；③Somebody had just done something when…。
如：We were having a meeting when someone broke in．We were about to set off on our way when it suddenly began to rain．此外，when还表示原因，“既然”。
如：It was foolish of you to take a taxi when you could easily walk there in five minutes．5．while作为并列连词，意为“而，却”，表示对比。
如：He likes pop music，while I am fond of folk music．6．如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when，while与as可互换使用。
如：When／While／As I was walking down the street，I came across an old friend of mine．【题组训练】用when，while，as填空：①_____I was walking down the street，I noticed a police car in front of the store．②_____John arrived，I was cooking lunch．③_____he grew older, he lost interest in everything except gardening．④How can he get good grades_____he won't study?⑤I was wandering through the street_____I caught sigh of a tailor's shop．⑥_____the grandparents love the children，they are strict with them．二、as soon as，immediately，directly，instantly，the moment．the minute，the instant，once (一…就…)这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一…就…”。
从句中用一般时态代替将来时态。
如：The moment I hear the voice，I know father is coming．The boy burst into tears immediately he saw his mother．注意：no sooner…than…；hardly／scarcely…when…这一结构的时态搭配：no sooner 与hardly／scarcely引导的句子谓语动词应用过去完成时，而than与when引导的句子谓语动词应用一般过去时。
此外，当把no sooner和hardly／scarcely提到句首时，应用倒装语序。
如：I had hardly got home when it began to rain．Hardly had I got home when it began to rain．【题组训练】汉译英：①一到家，他们就会打电话．____________________________________________________________②他一见她就笑．____________________________________________________________三、till, until和not…until1．肯定句：主句谓语动词必须是延续性动词，主句、从句都为肯定式，意为“某动作一直延续到某时间点才停止”。
如：He remained there until she arrived．You may stay here until the rain stops．2．否定句：主句谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。
如：He won't go to bed till／until she returns．3．till不可以置于句首，而until可以。
如：Until you told me I had no idea of it．4．not…until句型中的强调和倒装用法：It was not until you told me that I had any idea of it．(强调句型)Not until you told me did I have any idea of it．(not until置于句首，主句要倒装)【题组训练】句型转换：I didn't leave until she came back．①_____ _____she came back_____ _____leave．②_____ _____not until she came back_____I_____．四、before和since1．若表达“还未……就……；不到……就……；……才……；趁；还没来得及”时，需用连词before。
如：We had sailed four days and four nights before we saw land．We hadn’t run a mile before he felt tired．①______________________________________(在你还未忘记之前，请把它写下来)．②__________________________________(我还未来的及说话，他已经为我量好了尺寸)．2. it will be/ was +一段时间+ before…多久之后才……。
