试题分析：通过分析句子结构，可知这个句子中包含一个非限制性定语从句，that不能引导非限制性定语从句，只能用which      。   
点评：非限制性定语从句引导词的特殊情况，1．非限制性定语从句不可用that引导，在非限制性定语从句中用who(作主语) / whom(作宾语)指人，用which(作主语 / 宾语)指物，用whose作定语(指人 / 物)。例如：The famous basketball star, who tried to make a comeback, attracted a lot of attention．这位试图打反击的著名篮球明星吸引了众人的关注。The film, whose director is an old man, is very instructive．这部电影很有教育意义，它的导演是位老人。2．关系代词在非限制性定语从句中作宾语时不可省略，若指人时，只用whom，不用 who。例如：York, which I visited last year, is a nice old city．我去年访问过的约克是个古老而美丽的城市。Please give the book to Jessica, whom we met in the hall just now．请把这本书交给杰西卡，就是刚才我们在大厅里遇到的那位。3．非限制性定语从句不可用why引导，需用for which替代why。例如：None of us accepted the reason he explained, for which he was absent．我们没有一个人接受他所解释的缺席的理由。
