很多同学选了D,而正确答案却是C。出现错误的原因是弄不清none与nothing的区别。现请看:
1) none = not any, not one 一点也没有；一个也没有，即数量概念。既可指人，也可指物，代指上文提到的事物，含特指概念。如:
He wants me to lend him some money, but I have none at hand.
他想要我借些钱给他,但我现在手头上一个子儿也没有。
They asked for nine books, but there is / are none in the library at
present. 他们需要九本书,但目前图书馆一本都没有。
2) nothing = not anything, 意为"没有任何东西;什么也没有"，强调内容，只能指物，泛指。如:
He felt hungry, but he could find nothing to eat in the kitchen.
他饿了,但在厨房里他没有找到吃的东西。
Nothing in the world is difficult if you put your heart into it.
世上无难事,只怕有心人。
