初级问题
首先，可以很容易地把握本段对话的情况是为了买礼物逛商场。提到的要买的东西有两件，一个是blow dryer，一个是DVD player。如果听对话的时候特别留意for their parents，可以注意到DVD player for our parents这句话，这就是正确答案。

【正确答案】 B

【答案解析】中级问题
在给Sally买电吹风作为礼物的提议后面，很自然的会出现买这个东西的理由。只要想到了选项把原来对话中的doesn't work anymore换成了broken，就可以很容易地解决本题。虽然单独看每个选项都好像很合理，但是选择答案时一定要以听到的对话内容为根据。

【正确答案】 C

【答案解析】中级问题
如果理解了对话的脉络，可以预测解题线索会出现在哪个部分，然后只集中于此部分。在要买东西的前面应该是在讨论选择商品。所以有关支付的内容会在最后部分出现。或许有考生不知道by credit card和by charge是同样的意思，但是由于其他选项的意思离信用卡比较远，所以选出正确答案也不难。
