Why does the woman want to buy a gift?

[解析]事实细节题。题目询问女士为何要买礼物。由女士的话“我侄子吉姆下周就要从大学毕业了，我想给他买件好礼物”可知，女士买礼物的原因是选项D(庆祝她侄子大学毕业)。
选项A(表示她对他的爱)和选项B(她侄子让她买的)在对话中根本没有提及，应排除。选项C(为了庆祝她侄子的生日)对话中虽然谈到她侄子的生日，但讲的却是去年女士的弟弟给侄子送的生日礼物，因此，与本题不相关，也不正确。

【正确答案】 D

【答案解析】[听力原文]
Who bought Jim a pen?

[解析]事实细节题。题目询问谁为吉姆买了钢笔。由女士的话“去年我弟弟给他买了钢笔作为生日礼物”可知，钢笔是女士的弟弟买的，所以选D项(女士的弟弟)。
此题关键要弄清人物之间的关系。听清题目的信息，并进行合理推断就不会错选其他的选项。选项A(这位女士)虽然与听力内容相关，即她想给吉姆买礼物，但她要买的是网球拍；选项B(吉姆的兄弟)在文中并未提及，而选项C(吉姆)只是接受礼物的人，故均应排除。

【正确答案】 B

【答案解析】[听力原文]
What is the gift the woman bought at last?

[解析]题目询问这位女士最后买的是什么礼物。由男士的建议及女士的反应可知正确答案应是选项B(网球拍)。
选项A(一副象棋)和选项D(钢笔)是男士一开始给女士建议的礼物，但女士都没有选择购买，因此均错误。C项(一本关于运动的书)在对话中并未提及，对话中只是提到说吉姆喜欢运动，因此也不正确。
