Question

(2013·辽宁六校高三联考)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; sit	B．providing; sitting
C．providing; sat	D．provided; sat

Answer 1

C

C　考查非谓语动词。句意：在通往山顶的蜿蜒小路上走了几个小时后，游客们都聚集在遮阴的树下，坐下来休息。“providing shade”是现在分词短语作后置定语，修饰trees；sat与gathered是并列的谓语动词，要保持形式上的一致。
