You may give the dictionary to ----you think needs it necces

一般这种题会经常考到,你要记住you think 是一个插入语,同类的还有you guess ,i think 等等
这时你就把这些插入语拿掉,分析句子的主干于是这个问题就变成了
You may give the dictionary to ____needs it neccessarily
你会发现这里缺的是to后的宾语和need前的主语,而且是人
因此排除ABC,选D whoever=anyone who
整个句子为You may give the dictionary to anyone who needs it neccessarily
