8．Mary studies English by tapes．（ ）| A． | listening | B． | listen | C． | listening to | D． | listen to |
分析 玛丽通过听磁带学习英语．
解答 答案：C．考查动名词．句意"玛丽通过听磁带学习英语．"．listen不及物动词．listen to固定搭配．"听…"，因此A，B不正确．by这里是介词，后跟动名词listening．因此D不正确．答案是C．
点评 动名词的形式是动词+ing，动名词从它的名称上就知道它具有动词和名词的功能，因此它在句中，可作主语、表语、宾语、定语．要结合语境选择合适用法，注意动名词变法．
