B
need 作为情态动词,need do sth,否定其后加not
need作为行为动词:need to do sth或need sth,否定要用其它助动词

B.need not “不必”的意思
在这里,need 是情态动词,不用变单三。
不能加助动词,否定形式是needn't

B 情态动词
要是实义动词:need to do

B
如果有 doesn't need to 也可以选
needn't do 情态动词
助动词(一般否定)+ need to do
need doing =need to be done 两个都是 实义动词用法

你好。答案是B.
B.need not do it -------是情态动词结构
如果选D,就必须是-- - - doesn't need TO do it -------是实意动词结构

B
