M: What did your doctor prescribe for you?
W: Well, he said there was no need for me to take any medicine if I ate well-balanced meals.
Q: What did the doctor mean?
正确答案：D
解析：医生说饮食平衡的话就不需要吃药，所以女士应该选择合适的食品，即D。根据选项可以预测信息点是女士的问题应该如何解决。假设条件句if后面的内容往往就是出题点。

W: Could you tell me what I should do if my car breaks down?
M: Well, I'm sure you won't have any trouble, Mrs. Smith, but if something should happen, just call this number. They'll see that you get help.
Q: What does the man really mean?
正确答案：A
解析：男士给女士一个电话号码，说可以打电话寻求帮助。所以选择A。根据选项可以预测问题是（男士建议或答应）女士出了问题怎么办。捕捉虚拟语气和祈使句是本题解题关键。D选项干扰性较大，男士给女士一个号码，但是又补充了一句，说“他们会帮助你”的，说明电话号码并非男士自己的，也就是说提供帮助的人并不是男士。
