2.I've ordered some pizza,so we _______ worry about cooking when we get home tired.( )| A. | can't | B. | mustn't | C. | needn't | D. | may not |
分析 我已经点了一些披萨,所以当我们疲劳到家的时候,不必担心做饭的问题.
解答 答案:C.Can't不可能;做不到;mustn't不准,不允许,一般和规则搭配使用;needn't 不必;may not也许不;根据I've ordered some pizza,所以到家的时候,不必担心做饭的问题;Need既可以作为情态动词,也可以作为行为动词.当它作为情态动词的使用常常用于疑问句和否定句中,表示"不必".故选C.
点评 本题考查了情态动词的用法.解答时注意区分辨别句意以及所给选项的意思.
