【题目】__________ snacks and drinks, but they also brought cards for entertainment when they had a picnic in the forest.

A. Not only they brought

B. Not only did they bring

C. Not only brought they

D. Not only they did bring

【答案】B

【解析】当 not only…but also. . . 句型中的not only位于句首 时，前面分句要用例装结构。当谓 语部分是实义动词时，要借助于助 动词，构成do/did/does +主语+谓 语动词。
