问题描述：
She looks tired and ___ have a rest. A. need to B. needs to C. needs D. does to need
She looks tired and ___ have a rest.
A. need to B. needs to
C. needs D. does to need
我知道选B但是为什么选B
答
she是第三人称，后面“looks tired”与“_ a rest”是并列的，所以“-”是单数动词，不是“B”就是“C”或“D”，然后句型need to do sth.需要做某事，就选了B。D的话，要表示强调应该用“does need to”。
答
she是第三人称,后面动词应为第三人称单数,排除A.
need有个固定搭配：need to do sth
D选项的话,do 作为助动词,在这里没有does to need的用法
