第一题为什么不选D,ask of 怎么理解
第二题中的Had it been at all possible 怎么理解 做什么成分
第三题中的选项A 也有剩下的意思为什么不选A

1,--Today,are you free now I have a favor to ask of you.--_____A It is a pleasure B Go ahead C Help yourself D Ask,please2,Had it been at all possible I would have gone to visit him in the hospital,but I ___fully occupied the whole of last week.A am
1.第一题楼上正解,不再赘述.
另：Go ahead.“说吧”
2.答案：B.
1) Had I been at all possible = If I had been at all possible
这是if引导的条件状语从句的倒装用法（if同时要被省略）.
因为是对过去动作的虚拟,所以从句用过去完成时,主句用“would/might/might have done sth”结构作谓语.
倒装即可把从句的had/should/were提前至if从句句首,再省略if.
2）该题but后面是实际的过去的情况,所以不用虚拟语气,且时态只能使用一般过去时（由时间状语the whole of last week所决定）.
3.B
原因很简单,leave/remain都要“留下”之意,但是remain是不及物动词,没有被动语态；而leave是及物动词,在此题中必须使用被动语态,因为leave的宾语就是句子的主语three young men.
再如：the remaing 5 minutes 剩下的5分钟（remain无被动,所以用其现在分词做定语）；
There is only one minute left.只剩下1分钟了.(leave用被动,做后置定语).

第一题，i have a favor to ask of you.意思是说我有件事想问问你（请你帮帮忙）。 虽然D选项中字面意思是对的，但是这种表达太中国式了，英语中不会这样用的。应该选B比较恰当。
第二题，你所提问的部分，意思是说，如果可能的话(我会去医院看他的),这是一种特定的虚拟语气的表述方法。
第三题，LEFT如果作剩下的含义一般不会形容人的，只是形容物。比如说菜还剩下多少...

第一题，i have a favor to ask of you.意思是说我有件事想问问你（请你帮帮忙）。 虽然D选项中字面意思是对的，但是这种表达太中国式了，英语中不会这样用的。应该选B比较恰当。
第二题，你所提问的部分，意思是说，如果可能的话(我会去医院看他的),这是一种特定的虚拟语气的表述方法。
第三题，LEFT如果作剩下的含义一般不会形容人的，只是形容物。比如说菜还剩下多少。如果用人的话一般是另外一个含义“离开”。所以这题可能选B比较好
