题目内容
5.-We didn't see Robert at the opening ceremony yesterday.-No,he _______ it.( )
A. | mustn't have attended | B. | needn't have attended | ||
C. | needn't attend | D. | didn't need to attend |
分析 ---在昨天的开幕式上我们没有看到罗伯特.
---是的,他没有必要参加.
解答 答案:D
根据回答句"No"可知,Robert 昨天确实没有来."need to do"意为"必要做…"为实义动词,结合"yesterday"时间,所以否定形式为"didn't need to".need+do则为情态动词,need+to do则为实义动词.
点评 本题考查情态动词.难度适中,考生需掌握情态动词的用法,比如need做情态动词和实义动词的区别,在具体的句子中正确使用.
