rather than 用法小结
rather than 是一个并列连词,用法比较复杂,现归纳如下:
1.rather than 与would 连用时,构成“”句式,意思是“宁愿……而不愿……”,表示主观愿望,即在两者之中选择其一。例如:
She'd rather die than lose the children.她宁愿死也不愿失去孩子们。
2.rather than 不与would连用时,表示客观事实,意为“是……而不是……;与其……不如……”。它连接的并列成分可以是名词、代词、形容词、介词(短语)、动名词、分句、不定式、动词等。现分述如下:
(1)连接两个名词或代词
He is an explorer rather than a sailor.与其说他是一个海员,不如说他是一个探险者。
You rather than I are going to go camping.是你而不是我要去要野营。
注意:rather than 连接两个名词或代词作主语时,谓语动词应与rather than 前面的名词或代词在人称和数上保持一致。
(2)连接两个形容词
The sweater she bought was beautiful rather than cheap.与其说她买的这件羊毛衫便宜不如说它漂亮。
(3)连接两个介词(短语)或动名词
We will have the meeting in the classroom rather than in the great hall.我们是在教室里开会,不是在大厅里。
She enjoys singing rather than dancing.她喜欢唱歌,而不喜欢跳舞。
(4)连接两个分句
We should help him rather than he should help us.是我们应该帮助他而不是他应该帮助我们。
(5)连接两个不定式
I decided to write rather than(to)telephone.我决定写信而不打电话。
注意:rather than 后接不定式时,不定式可以带to,也可以不带to, 如上句。但rather than位于句首时,则只能接不带to 的不定式。如:Rather than allow the vegetables to go bad, he sold them at half price.他唯恐蔬菜烂掉,把它们以半价卖掉了。
(6)连接两个动词
He ran rather than walked.他是跑来的,而不是走来的。
注意:这里rather than 后用了walked,而没有用walk,表示客观事实,而不是主观愿望。如果换成walk,则作“宁愿……而不愿 ……”解。
would rather的用法
一、would rather意思是“宁愿、宁可、更、最好、还是为好”,后接动词原形,常省略为’d rather,表示优先选择的一种方式
其否定形式是would rather not do sth。would rather没有人称和数的变化,所有的人称一律用would rather。
“would rather+动词原形”是英语中常见的一个惯用句式,美国英语中多用had rather。would(had)在此决无“过去”之意,它是一个情态助动词,且无词性、时态
变化。
例 Mr Li would rather not listen to rock music.李先生不愿意听摇滚音乐。
If you’d rather be alone, we’ll all leave here.如果你宁愿独自呆着,那我们都离开这儿。
He’d rather work in the countryside.她宁可到农村去工作。
You would rather stay at home and do some reading this evening.今晚你最好呆在家中读点书。
二、如果在两者中进行取舍,表示“宁愿……而不愿……,与其……宁可……”的意思时,则可用would rather…than…或would…rather than…的句型
例 I would rather watch TV at home than go to the cinema.我宁可在家看电视而不愿去看电影。
The children would walk there rather than take a bus.孩子们宁愿步行去那里而不愿乘公共汽车。
请注意 1)would rather…than…/would…rather than…也可以颠倒为:rather than…would…。Would(rather)和than后都接不带to的动词不定式,若选用的动词相同,那么than 后的动词可以省略。
