His homework______, but it _____.
A．needs correcting; needn’t rewriting
B．need be corrected; doesn’t need to be rewriting
C．needs correcting; needn’t be rewritten
D．needs to be corrected; needn’t to be rewritten
答案
C
本题还是考查need作为行为动词和情态动词的用法。“需要修改”用行为动词need可以说成needs correcting =" needs" to be corrected，用情态动词need可以说成need be corrected，参考以上表达方式来进行第二空的选择，可见只有C项的两部分都正确。
