你可以明天完成。

must必须；一定；may可以；可能；can’t不能；不可能；needn’t不必，没有必要。

故应选D。

考查动词need用法辨析。
need用作情态动词时常和不带to的不定式一起作谓语，否定式是将not置于其后，并有其否定的缩写形式needn't，在疑问和否定句中不加助动词；可知BCD三项表达错误。
用作行为动词时，need是一个普通的及物动词，用在肯定、否定和疑问句中均可，接不定式时要带to。
本句need用作及物动词，根据句意结构，故选A。

can’t 不可能，否定推测；mustn’t 禁止，不表推测；needn’t 不需要；may not 可能不是，表不确定的推测。
根据回答“No”和“His is blue.”可知这里说话者表达完全否定推测，故选A。
【点睛】在情态动词表推测时，很多同学会搞混can’t和mustn’t，认为他们都表示完全否定的推测，在做题时容易误选。
can’t 不可能，表示完全否定的推测，但是mustn’t 禁止，并不用于表推测。
