Question

【题目】________ as a volunteer teacher in Tibet for a year, Linda has become more experienced.

A. To workB. WorkingC. Having worked D. Worked

Answer 1

【答案】C

【解析】

试题分析：考查非谓语动词。句意：Linda作为志愿者老师在西藏工作了一年，她已经更有经验了。分析句子，逗号后面是主句，所以空格处应该用非谓语动词，根据与句子主语Linda之间是主动关系，并且动作发生在谓语动词之前，可知用现在分词的完成式表示原因。故选C。
