1 A
When and where to build the new factory 作主语,表示一个事件,作为一个整体,排除B与D,根据句意应该是被动语态,再排除 C
2 C
固定句型：sth is + adj.+ to do sth .
3 C 固定句型：it 's +一段时间+ since + 句子（一般过去时,我认为has left 应该是 left ）主语是三单,排除B
4 C 是的,你可以
could和might用在疑问句中,表示委婉的请求.但是它们并不能用在答句中,而只能用相应的can/may来回答；will不能对应问句.
答案Yes,you can.也是正确的.
5 C 主句是一般过去时,从句要用相应的过去时.
6 C 证明
他的话被证明是有用的;
祝你假期愉快!加油!不明白再问!
再问：第二题的答案是C才对，但我不明白是为什么？
再答：我选的就是C呀把它作为一个固定句型（ Sth is + 形容词+ to do sth‘ 做……是怎么样’ ) 来记就OK了
