选A,
need的用法：
1,need做情态动词,need do sth “need ”后面是不加to
的,也不可以跟“doing”
ps:这里的need后面是要加个动词原形的!
2,need做实意动词,need to do sth 表示某人要做某事
need diong是某事需要被做是动的
意思
例如：I need to finish the work before nine\'o clock.
The work needs finishing before nine\'o clock.
need
need not do sth.情态动词
don't need to do sth 一般动词
所以选A
选a
need 作实意动词时need to do sth/sth表示 需要,有...必要
作情态动词时need do sth需要,必须
need 有时后面也跟doing表示被动如The chair needs repairing=The chair needs to be repaired
前两者区别于否定的形式，这样就可以排除c
最后一个区别于意思bd
need not doing 不需要做，但已经做了
need not to 不需要做，还没做
后面是虚拟语气，所以不选bd
need在这里不做情态动词
所以选A
