It's to travel by plane than by train.(quick)到底是用形容词还是用副词呢?
quickly

填qucik 形容词
因为It's quick。是主系表结构 要接一个形容词来做表语
希望对楼主有所帮助~~

当然用quickly咯，因为quickly这个副词是修饰travel这个动词，而不是后面的成分。

It's quicker to travel by plane than by train.
形容词，因为是It's +adj.+to do的句型

quick

副词 服务travel的

用形容词，还要用形容词的比较形式quicker 因为这里有个比较than 而且比的不是动作而是乘飞机和乘火车这个两种方式。

形容词 肯定的 修饰的是名词
