2 B 否定反问 如果是be动词,则是isn't he;look不是be动词

2B
3A
解释语法不是我的的强项,答案应该没错。

1.know后面是know的宾语,所以肯定是陈述语句,所以B错。
how long 表示一段时间,come buy都是短暂性动作,A C错.
D对。have been here (在这儿)
2.谓语是look,肯定形式,所以是doesn‘t he,选B,不要看后面的形容词。
3.until一直到;since 自从; when当什么时候; before ...

1.D 首先考虑语句顺序问题,do you know后接的是宾语从句应用陈述句语序,所以排除B。再考虑只有延续行动词才可以用how long提问,come buy是瞬间动词,排除AC,所以选D.
2.B首先look是实意动词应用助动词does提问,且原句是肯定的,所以反义要用否定的。
3B自从,how long问的是一段时间...

1.D
首先排除B,因为宾语从句按陈述句语序排列;然后是A和C,因为bought和come都是短暂性动词。
2.B
look是动词,所以排除C和D,反意疑问句是“前否后肯,前肯后否”,与后面的形容词无关。
3.B
看到How long的时间特殊疑问句,用Since和For回答,Since+准确时间,For+一段时间。...
