题目内容
1．Mrs．Brown does what she can______ her daughter with her study．（ ）| A． | help | B． | to help | C． | helping | D． | helps |
分析 Brown夫人尽她所能的去帮助她女儿学习．
解答 答案：B．根据Mrs．Brown does what she can这一部分的分析可知，what she can是作前面的定语表示强调，表示他能做他所有能做的，所以在选择后面的谓语动词时不要受what he can的影响，直接根据前面的he can do去选择，所以do的后面应用动词不定式表目的，故选B．
点评 此题考查不定式作目的状语．做此题时一定要格外小心，不要被句子的一些成分干扰，提取出句子的主干非常重要，然后再按照正常的答题思路解答就可以了．
