连词和连接词的区别

连词在英文里叫conjunction,连接词叫linker, linking devices等等。

连接词很大一部分是副词,包括therefore, thus, however, nevertheless, then, moreover, besides等等。

还有一些是几个单词放在一起的词组,包括in contrast, by comparison, on the other hand, in addition, 等等。

要点1 并列连词和连接词的对比

连词有两种,一种是并列连词,譬如说so, but, or, and等。这种连词的特点有两个:1 后面可以是完整的句子,也可以是不完整的句子 2 前面可以加句号,也可以是逗号。

 

例句1Students study hard and revise for exams. (√)

解析:and后面的句子少了一个主语。

 

例句2 Students study hard. And they want to pass the exam immediately. (√)

例句3 Students study hard, and they want to pass the exam immediately. (√)

解析:And 前面有句号,也可以是逗号。

 

对比:连接词,一般后面是独立的句子,前面一般是句号或者是分号(但是不能是逗号)。

例句4Students study hard; therefore, they have the potential to pass the exam immediately. (√)

解析:therefore前面是分号,后面是独立的句子。

 

要点2 从属连词和连接词的对比

第二类连词是从属连词,譬如说because, while, since, as, although等等,这些词的特点有两个:1 一般连接两个独立的句子  2 如果在两个句子的中间出现,前面要么不加标点符号,要么加逗号(但是不能加句号)。

例句5Students study hard because they want to pass th exam immediately. (√)

例句:Students study hard. Because they want to pass th exam immediately. (X)

解析:because前面没有标点符号,也可以加逗号,但是加句号是错的。

 

然后,大家可以对照例句4,看看和连接词的区别。
