1.句意为"我问她我是否应把窗户关上".选择should 表应该含义,其它与语意不符.
2.order 后的宾语从句中应为虚拟语气,主语加should再加动词原形,should可以省略.
3.人类必须即刻展开与污染的抗争.must表示主观需要,have to 表客观需要,而且时态不符.
4.他被警方带走了.他一定是被错认为小偷了.must have done 是对过去发生事情的肯定语气的推测.此处为被动语态.
5.你还记得我们何时去的长城吗?
记不太清了,会不会是去年夏天?
could have done用在疑问句中表对过去发生事情的推测.
1.现实语法习惯，在因为宾语从句要用过去将来是，助动词由一般将来时的第一人称助动词"shall"变成"should"。
2.固定用法 省略shoule
3.A表示主观意愿，B表示客观迫使，所以用A。
4.被动语态
5.表示对过去肯定的推测，但只有肯定句才能用"must",这里是疑问句，所以用"could"。
看我这么努力，把份加给我吧！
