the weather today is worse than it was yesterday这句话为什么用it was yesterday?
问题描述：
the weather today is worse than it was yesterday这句话为什么用it was yesterday?
the weather today is worse than it was yesterday.
为什么最后是It was yesterday呢?它（天气）是昨天.感觉很别扭啊
为什么不能写成是：it yesterday或者the weather yesterday?
答
than 前后是两个句子,如果用it yesterday那麽这个句子就缺少成分,原句中的it was yesterday省略了 worse 这个词,但原句这样是对的,而如果用the weather yesterday则显得累赘重复,一般比较好的是尽量不重复前句提到的主语,这样显得句子更上档次一些.
