问题 Although it is a very tough task, you______afraid of any difficulties.
选项 A、need not to be
B、need not
C、don’t need
D、need not be
答案D
解析 该题是语法结构题，考查情态动词的用法。need既可做实义动词，也可做情态动词。当need做实义动词时，有时态和人称变化，如：He needs to go home．他需要回家一趟。当它是情态动词时，无人称变化，只有现在时，并且用在否定句、疑问句和条件句中，如：You needn’t work so late．你不必工作得这么晚。因此，根据题意和语法规则，选项D为最佳答案。
