并列连词和从属连词的用法:连词是连结单词、短语、从句或句子的虚词, 在句子中不单独作句子成份。连词按其性质可分为:
1、并列连词 如:and, or, but, for, 等, 连接并列的词与词,短语与短语,句子与句子。如:Rice and potatoes are common foods. (词与词) Today we can travel by plane. (短语与短语) Many trees lose their leaves in winter, but evergreen trees do not. ( 句子与句子)
关联连词是一类成对使用的连词。 如:both……and……, not……but…….,not only……but also…… not only…but… as well either……or……, neither……nor…… 关联连词必须后接同样的语法结构。 如:Either the windows were opened or the door was opened.
2.从属连词 如:that, whether, when, because, though等, 用以引导名词性从句和状语从句。
3.从属连词引导的从句不可以被断成一个句子。 如果断开,就错了。如:When the alarm clock rang.(不完整)
4. though (although)引导让步状语从句,because 引导原因状语从句, 所以 though (although)不能和并列连词but ,because不能和并列连词 so一起使用。 只能单独使用。
例1: he did not know much English,he got out his dictionary and looked up the word. • As B. For • C. Since D. Because • 答案:A。
提示:for,because和as虽皆可作连词用,表示“因为”,但用法有些区别。for引导的分句总是置于另一分句之后,常常对前一分句加以解释,两个分句之间,总是用逗号分开。because引导的原因状语从句时,往往以why问句,语气比较重,传递的往往是对方未了解的新信息。as引导的原因状语从句时,往往是对方也知道的信息。本句是他拿出词典查,显然,“他知道的英语单词不多”,这是明摆着的事,所以用as最恰当。提示:for,because和as虽皆可作连词用,表示“因为”,但用法有些区别。for引导的分句总是置于另一分句之后,常常对前一分句加以解释,两个分句之间,总是用逗号分开。because引导的原因状语从句时,往往以why问句,语气比较重,传递的往往是对方未了解的新信息。as引导的原因状语从句时,往往是对方也知道的信息。本句是他拿出词典查,显然,“他知道的英语单词不多”,这是明摆着的事,所以用as最恰当。
