was就只是表过去,单独这句没有直接的时态限制,除非有上下文.
To climb the mountain was hard for me.这就是原本to do直接做主语的样子,主语太长了,头重脚轻,所以改成It做形式主语,把不定式挪到后面去,这也是“形式成分”存在的意义.
it was hard for me to climb the mountain为什么用was,用is可以吗?用to climb the mountain作主语怎么写
it was hard for me to climb the mountain为什么用was,用is可以吗?用to climb the mountain作主语怎么写
