问题描述:
diamonds do not look very impressive as they are mined钻石刚开采时并不光彩照人.
这里为什么是do not 而不是are not
答
如果用are的话,那look就不用原型了啊,look是系动词啊,不能再有Be动词do不也是动词吗亲,这里是助动词啊,一个句子是不能出现两个动词的,否则另一个动词要用非谓语形式亲,这句话用are怎么改不可以用be的,be是:是的意思,翻译不通啊,而且你用are的话,就是用ing形式,表示正在经行的,也不对啊,你年纪啊diamonds are very impressive as they are mined对吗,在百度HI上聊``再问要把分了这个是可以的,
