6.(单选题) __ He looks very hot and dry. __ So ( ) if you had a temperature of 39.A. would youB. will youC. would you have beenD. do you

本题考查虚拟语气的倒装结构。关键点在于：

1. if从句中的"had"表明假设与现在事实相反，属于虚拟现在时；
2. "so + 情态动词 + 主语"的倒装结构需与主句的虚拟语气形式一致；
3. 正确选项需满足情态动词+动词原形的结构，且无需额外时态修饰。

语境分析

原句表达假设关系："如果你体温达到39度，你也会看起来很热且干燥。"
虚拟语气结构为：
If you had a temperature of 39, you would look very hot and dry.
倒装后变为：
So would you look very hot and dry if you had a temperature of 39.

选项辨析

• A. would you
  符合虚拟语气结构，直接延续主句中的would。
• B. will you
  will用于事实语气，与虚拟语气矛盾。
• C. would you have been
  have been为完成时态，与原句中的look（瞬间动作）不匹配。
• D. do you
  do用于强调或倒装，但此处需虚拟语气。
