1、I live in Beijing, where is the capital of China. 解析：此题为四星级题。此题考查定语从句中的'非关系代词、副词的用法。where改为which。这是一个非限制性定语从句，从句中缺少主语，主语应由关系代词来充当，所以应将关系词where改为which。此句应改为：I live in Beijing, where there are lot of places of interest.先行词在定语从句为地点状语，所以应用关系副词where。如： e.g.This is a house that / which I visited yesterday. This is a house where I spent a happy childhood.
2、If the book you want is out, you may ask for it to be called back for you, and whether you pay the cost of sending a post card, the librarian will write to you. 解析：此题为五星级题。whether改为If。此题考查if与whether作为连词的区别。此处为if引导的条件状语从句，表示"如果……"；如用whether，则表示"是否"，语意不通。 在下列情况下一般只用whether：引导介词后的宾语从句、主语从句、表语从句、同位语从句或在whether to do, whether…or not…中。 e.g.Whether we'll go camping tomorrow depends on the weather. I asked him whether he would go or not.
3、It is a very important exam but I can't afford to fail it… 解析：此题为五星级题。此题考查并列句之间的关系，在此两句为因果关系，所以根据句意，but改为so。
4、When I was on the stage the next day, I felt so nervous as I shook like a leaf. (NMET2000) 解析：此题为四星级题。考查so…that引导的结果状语从句。把as改为that,结果状语从句一般由so that，so…that，such…that引导。 e.g.The box is so heavy that nobody can move it. It is such a heavy box that nobody can move it. He got up later so that missed the first bus. 锦囊妙计 在连接手段上应侧重考虑：
5、若为复合句，首先判断属于何种从句，然后根据主、从句之间的关系判断连接词使用是否准确或是否有遗漏或多余现象，要注意句子结构的完整性。
6、若为并列句，要判断句与句之间的关系是并列、转折、选择、递进还是让步关系，从而选择恰当的连词。
7、英语句子衔接加连词知识点 高考英语短文改错命题的一个重要方面就是考查连接手段，连词使用不当会造成上下句不衔接。英语中的词与词、句与句之间必须使用并列或从属连词。 案例探究
8、语句中的词与词、句与句之间必须使用并列或从属连词。
