rather than用法rather than固定+do吗?可以+to do 放在句首呢eg :Rather thou

1.rather than do
He told a lie rather than get his friend into trouble.
他宁愿说谎也不愿连累朋友.
Shall we go for a walk rather than watch television?
咱们不看电视,出去散步,好不好?
rather than后接动词原形表示主观抉择
rather than to do
I decided to write rather than(to) telephone.
我决定写信而不是打电话.
They prefer to die fighting rather than(to) live in enslavement.
他们宁可战死,也不肯活着受奴役.
13)I prefer to work rather than(to) remain idle.我宁愿工作而不愿闲着.
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.
接动名词
8)I always prefer starting early,rather than leaving everything to the last minute,
我总是愿意早开始而不愿意把所有事情都留到最后才做.
9)He was engaged in writing a letter rather than reading the newspaper.
他那时是在写信而不是看报纸.

rather than 可作连词词组使用，连接两个并列成分，表示在两者中间进行选择，意为“是 A 而不是 B ”、“要 A 不要 B ”、“宁愿 A 而不愿 B ”等，后面可以接名词、代词、形容词、副词、动词和动词不定式等。

1. 名词。例如：

He is a writer rather than a teacher.

与其说...

我们目前只学到后加do 别的不清楚

好像既可以加do，也可以加to do
