What kind of skills does the woman not have?

[解析] 本题考查对事实细节的把握。题目询问女士缺乏什么能力。根据女士的回答可知，B项(做生意)正确。
解答此类题目需要运用排除法。选项A(操作电脑)和选项D(打字)比较容易排除，因为对话中有直接相关的内容。但是需要注意的是选项C(收发传真)，不过根据对话中的“Besides I am good at operating common office machines like fax”也可排除此选项。

Which company did the woman work in?

[解析] 题目询问女士过去在哪里工作。在对话开头，女士就说“I have worked... first for a trading company, then a trust company.”，由此可以判断正确答案为选项A(贸易公司和信托公司)。
解答本题的关键是抓住对话中的关键信息，并能够听完整个信息。选项B(贸易公司)和选项C(信托公司)的回答都不全面；而对话中提到如果有重要的访问团来的时候，女士就要加班，因此选项D(访问团)也不符合题目要求。
