本段对话涉及到生病、建议等话题。
第一空：根据上句Not very well, I think I have the flu.（不很好，我认为我得了流感。）可知，我认为得了流感。根据答语It might be, I suppose, but it doesn't feel like it. I've had it for a few days now. I just feel really weak and tired all the time.（我想可能是这样，但它不像（普通）感冒。我已经病好几天了，一直感到虚弱和疲惫。）可知，此处通过对自己病情的描述，确定得了流感，所以用句子Are you sure it's not just a cold?（你确定不仅仅是感冒吗？）答案D。
第二空：根据上句I've had it for a few days now. I just feel really weak and tired all the time.可知，我感到很不舒服。下句Maybe you should go home and get some rest.（可能你需要回家休息。）也可以判断出，病人的情况确实很糟糕。答案C。
第三空：根据上句Yes,you are right.可知，我同意回家休息的建议。根据下句That’s true.（没错）可知，同意对方说的某种情况，用句子No one will thank you if you stay and spread it.（如果你留下来传播它，没人会感谢你的。）比较合适。故选G。
第四空：根据上句“让对方告诉史密斯先生”的请求可知，此处答语为肯定回答。答案选A。
第五空：根据常识和答语I’ll try my best.（我会尽力的。）可以判断，对方应该是对病人进行安慰。答案选F。
