非谓语动词
34.(2015·湖南高考)Sometimes I act as a listening ear for fellow students ________ what is bothering them.
A．to talk over B．talked over
C．talk over D．having talked over
解析：选A 考查非谓语动词。句意：有时对我的同学来说我充当了听众的角色，以便与他们详细聊一聊正在困扰他们的事情。本句用动词不定式作目的状语。
30．(2015·湖南高考)When the clerk saw a kind face wrinkled in an apologetic smile, she stood rooted to the ground, ________ whether to stay or leave.
A．wondering B．wonder
C．to wonder D．wondered
解析：选A 考查非谓语动词。句意：那名店员看到一张友善的脸，脸上因歉意的微笑布满了皱纹，这时她愣在了那里，琢磨着是走还是留。句子的主语she与wonder之间是主动关系，且wonder与主句谓语stood是同时发生的，故用现在分词作伴随状语。
24．(2015·湖南高考)Video games can be a poor influence if ________ in the wrong hands.
A．to leave B．leaving
C．leave D．left
解析：选D 考查非谓语动词。句意：如果落在不合适的人的手中，电子游戏就会有一个很坏的影响。leave的逻辑主语是video games，主语video games与leave之间是被动关系，故用过去分词。if left ...是“连词＋过去分词”构成的状语从句的省略。
