rather than不是介词词组吗?为什么prefer to do rather than do中rather than后面加do?

介词后面不是应该加doing吗?

prefer to do…rather than do 表示平行并列结构，前后do的形式不同就不对了。
其实是省略了to。

不是 两个do 都与to对应的 都是不定式

rather than 是连词，连接前后相同的成分，如： 1. The color is green rather than grey. 这是绿色而不是灰色；连接了名词。 2. I prefer to stay home rather than （to) go to the party. 我宁可呆家里也不想参加聚会,；连接 了动词不定式。

5。rather than do He told a lie rather than get his friend into trouble。 他宁愿说谎也u不c愿连累朋友x。 Shall we go for a walk rather than watch television? 咱们不u看电视，出去散步，好不b好？ rather than后接动词原形表示1主观抉择 rather than to do I decided to write rather than(to) telephone。 我决定写信而不i是打电话。 They prefer to die fighting rather than(to) live in enslavement。 他们宁可战死，也t不x肯活着受奴役。 86)I prefer to work rather than(to) remain idle。我宁愿工v作而不j愿闲着。 rather than 后接不t定式时，不f定式可以6带to，也m可以0不t带to, 如上p句。但rather than位于q句首时，则只能接不g带to 的不e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5半价卖掉了h。 接动名词 6)I always prefer starting early,rather than leaving everything to the last minute, 我总是愿意早开b始而不x愿意把所有事情都留到最后才a做。 6)He was engaged in writing a letter rather than reading the newspaper。 他那时是在写信而不n是看报纸。 2011-10-29 12:18:26
