1. The scholar standing over there is _____ the great mathematician Robinson himself.
A.no other than B.no other but
C.none other than D.no one but
2.If you _____ me,I shall be very grateful to you.
A.helped B.will help
C.are helping D.will be helping

问：第一题的no other than，no other but存在么？我在字典上没有查到这样的用法。只有other than啊。而no one but是什么意思？
第二题如果will表示意愿，愿意做时可以用b么？
两题答案分别是C、D

A."none other than":
ad. 正是(恰恰是)

例句与用法:
1. The tall figure that you saw was none other than our manager.你所见的那位身材魁梧的先生不是别人正是我们的经理。

2. The young man sitting at the desk was none other than our new teacher.坐在办公桌那儿的那个年轻人正是我们新来的老师。

B."no one but":
conj. 只不过是(只是)

例句与用法:
1. There is no one but is (=who is not) concerned about his future.没有人不关心自己的未来。

2. There is no one but wishes to get somewhere.
没有人不希望将来能有所成就。

C.第二道题单从表达上说B和D都可以，只不过为了和Shall be前后呼应，所以用D比起B看起来更好些（评论：时态语法题最无聊啦）。
