选择题中 no one和none的用法困惑 can't help do和can't help doing的用法困惑

解题思路：通过练习积累词汇，短语，句型结构；熟悉英语简单句型结构，英语语法；熟悉英汉翻译。
解题过程：
The old man had expected to see all his children when in hospital, but ____ came to see him. 答案是none，为什么no one不行？
none与数量有关，可回答how many，How much,表示"一个也没有"；而no one表示"什么人也没有"，可回答who。如：
-How many people are there in that room?-None.那个房间里有几个人？一个人也没有。
-Who was late today?-No one.今天谁迟到了？谁也没有迟到。
所以根据语境意思 "这个老人希望所有的孩子来看他"， all是强调数量，所以这一空用none.
The students all go to the PE class. _______is in the classroom. 答案是 No one. 那么这里为什么又不选none.
语境意思：学生们都去上体育课了。没有人在教室里。所以这一空强调"什么人也没有"，所以用no one.
He can't help_______ the answers when she can't work out the problems. A. turn to B. turning to
选B can't help do 是不能帮助做某事 can't help doing是情不自禁做某事。根据语境意思：当她解不出这些问题时她忍不住去参考答案。所以这一空用can't help doing结构，选turning to 。

最终答案：见上
