问题补充：

They the cat out for a walk now.

A. needn’t to take

B. don’t need take

C. needn’t taking

D. don’t need to take

答案：

A. needn’t to take

B. don’t need take

C. needn’t taking

(答案→)D. don’t need to take

解析：need可作为情态动词，后跟动词原形，否定形式是needn’t+动词原形，故不选AC，need也可作为实义动词，对于本题而言否定形式用助动词don’t，后跟动词可用to do或doing，故本题选D。
