单选题 Speaker A: I feel rather sick this morning. I don"t think I can concentrate on the work.
Speaker B: ______
Speaker A: I"m not sure, but I have got a bad headache.

A、 How long have you been sick?
B、 How are you feeling now?
C、 Do you have a high temperature?
D、 I"m sorry to hear that and I can"t help you now

【正确答案】 C

【答案解析】[解析] A说“今天早晨我感觉非常不舒服。我都无法集中精力来工作了。”请注意B问话后，A的回答是“我不太确定，但是头疼得很厉害。”可见选项C“你是不是发高烧了?”为正确选项，前后对话都在谈论实际的病情。A，B，D选项都无法和后面的答案构成对应关系，所以不选。
