【題目】They worry about them.Their children will come out in a few minutes.

A.needn’t

B.don’t need

C.not need to

D.didn’t need to

【答案】A

【解析】

句意:他們不用擔(dān)心他們,他們的孩子幾分鐘后會出來。

根據(jù)句意可知是一般現(xiàn)在時態(tài),didn’t need to過去時態(tài)的結(jié)構(gòu),排除D;need作為實(shí)意動詞時,否定句在need前加don’t,排除C;need作為實(shí)意動詞時,后面用不定式need to do作賓語,排除B;當(dāng)need是情態(tài)動詞時,后面接動詞原形,否定句在情態(tài)動詞后直接加not;故選A。
