题目内容
16.If you find free WiFi in public places,you _____ a password.( )| A. | needn't | B. | don't need to | C. | needn't to | D. | don't need |
分析 如果你发现在公共场所的免费WiFi,你不需要密码.
解答 答案:D
need 需要,既可以做情态动词,也可以做实意动词,做情态动词时,后跟动词原形,否定式是needn't;做实意动词时,常用词组need to do sth.或need sth.否定式用助动词do否定;结合题干you _____ a password,空格后是名词,结合句意:不需要密码,应该是don't need,故选D.
点评 本题考查的是动词need的用法,理解句意并掌握动词的用法是解答本题的关键.
