Question

After walking on the zigzag path to the mountain top for a few hours, the tourists gathered under trees ________ shade and ________ down to have a rest.

A.provided; sitB．providing; sitting

C．providing; sat D．provided; sat

 

Answer 1

C

【解析】 C 考察飛謂語動詞和句式分析。And連接gathered和第二空，所以第二空使用sat；第一空是非謂語動詞做定語，trees和provide構成主動關系，使用使用現在分詞的學生。
