At last,we found ourselves in a pleasant park with trees providing shade and ________ down to eat our picnic lunch.

A.sitting

B.having sat

C.to sit

D.sat

试题答案

D

解析：由于原句中we found ourselves… and ________ down to eat our picnic lunch中的and起并列连词的作用，所以空格处应作谓语动词与found构成并列谓语．

命题立意：本题实则考查了句式结构，此外题中要注意已给连词的作用．
