A
B
要解释可HI我.
一、A,其中all和what可以互换,都是竭其所能的意思;但两者不能合用,也不能两者都缺,因为do需要有作用的对象;
二、B,主要考察时态一致。
1 A all后面接主语从句时,连接词省略,后面的to是不定式
2 A 虚拟语气
1.A 如果用定于从句 前面有all,所以只能用that做先行词,故排除BC。D选项
they can 后少一个to
2.B吧应该...上面说老板刚刚问你什么?
回答是 老板刚刚问我tom是否已经做完工作
过去的过去...
第二个不确定
A
B
1.先排除C、D。all可以做代词,这里代所有老师们可以做的事,所以不用what
2.这里表示过去的过去。你可以看if前,一般情况下前面是过去时后面就是过去完成时,前面是一般现在时,后面就是一般过去时。
一、A,all和what都可以,都是尽自己所能办某事的意思;不能合用,但是不能省略,否则,do缺少承受动作的宾语成分
二、B,时态问题,由asked可知为过去,再往前推时态应为过去完成had finished。
