试题分析: 此题重点考查动词need的用法，它有两个词性，作为情态动词时经常用在否定句中，并且后跟动词原形；作为实义动词时后可跟名词，动词不定式，动词的现在分词（表示被动意义）,其否定形式要借助助动词do的形式.根据语境可知此句的含义是我们没有必要***那么快.根据语境和need的基本用法,可知D为正确答案.
点评：此题的关键要看怎样区分need的词性.A和D中的need是行为动词,但作为行为动词need的基本用法是need to do sth,A的答案是不对的;B和C都是情态动词,而need作为情态动词其后只能跟动词原形,故其也是错误的,故选D.因此区分need的词性是解题的关键,但要分析题***基本结构. |
