有一读者问：如何做这道选择题：
(1)— How's the young man?
— _____.
A. He's twenty B. He's much better
C. He's a doctor D. He's David
应选B,即 He's much better.因为 How is （或 are）后接表人的名词时，皆表示询问某人的身体情况，再如：
(2)How's your father?
(3)How are you?
如选择A，问题应该是：
(4)How old is the young man?
如选择C，问题应该是：
(5)What is the young man?
如选择D，问题应该是：
(6)Who is the young man?
