If you his wife’s income his own，the total of their income 3000 yuan.

A. add; to; will add up to

B. add; to; adds to

C. add up; to; adds up to

D. will add; for; adds up

答案：

(答案→)A. add; to; will add up to

B. add; to; adds to

C. add up; to; adds up to

D. will add; for; adds up

解析：考查if引导条件状语从句及词的用法。主句用一般将来时，从句用一般现在时表将来。排除D。Add...to 把...加在..., add up to总计达, add to增添。句意：如果把他妻子的收入和他的收入加起来，总计达3000元。
