I ____the address of the piace .I have been there.A .needn't B.don't need 选择理由是?
是place.
是place.
选B
needn't 是need作情态动词用,后面要跟动词原形,这句中the address是名词,因此不能用needn't
need sth.需要什么东西,这个need是实义动词,变否定时要加助动词 因此是：don't need
再问： 能出一道这种类似的题吗？
再答： You needn't hurry up because the train has alreay left. 你不用着急赶了，因为火车已经开走了。hurry up是动词，前面的needn't是情态动词，这里的needn't 也可以用 don't need to代替 need做实义动词时的用法是, need to do，疑问是：Do ... need to do..? 否定是：.. don't need to do（视情况助动词有可能变为does/ did）
再问： need do 有吗？
再答： need作情态动词，一般用于否定或疑问句，肯定句用得较少，也就是很少看到need do，一般都是need to do这种做实义动词的用法哦！
