常见考点汇总

一、 语法错误类

1. 粘连句(run-on sentences)

两个单句合并为一个并列复合句(compound sentence)的方式有：①“逗号+连词”连接，如and/but/yet/so/for等，表示并列或顺承、转折、结果、原因等关系；②“分号”连接，表示并列关系，且两个分句相对独立，相比“, and”连接的分句关系要松散一些；③“冒号”连接，表示后一个分句是对前一个分句的解释说明。

若两个单句以although, if, because, so that, in order that, when, where, who, whose, which/that等关系连词或关系代词连接，则构成相应的主从复合句(complex sentence)。

若两个SVO/SCP单句间没有标点，或仅以逗号连接，则构成粘连句。

例1：By the time she was twenty-one, Jane Austen had begun writing a novel which she initially titled First Impressions and which she later called Pride and Prejudice

(A) this is a book that many fans consider her best work

(B) since many fans consider this her best work

(C) the best work that many fans considered it to be

(D) a book that many fans consider her best work

(E) it is considered by many fans as her best work

【特别注意】：副词不能连接两个句子。常考的易错副词有：consequently, therefore, however, thus, hence, then, even等。以逗号连接两个单句时，若后一个分句以这些词开头，则须在它们前面加上一个连词，或将连接逗号改为分号。此外，使用consequently, therefore, however等词时，其后通常跟一个逗号。

【QUIZ】：判断以下句式是否正确。

(

( ( ( ( ( ( ) SVO, thus SVO. ) SVO, however SVO. ) SVO, but SVO. ) SVO, although SVO. ) SVO; therefore, SVO. ) SVO; but SVO. ) SVO; although SVO.
