Question

【题目】He ________ the potato chips until they were crispy.

A. stopped to cook B. didn’t stop to cook

C. stopped cooking D. didn’t stop cooking

Answer 1

【答案】D

【解析】句意：他直到那个薯片酥脆了他才停止炸薯条。stop to do sth停下来去做某事，stop doing sth停止做某事，not …until…“直到……才……”。结合句意，此处表示停止炸薯条，故用didn’t stop cooking，故选D。
