1.D
"if not more than"后面接的是"three thousand yuan",在这里省略了的.
"if not"的"not"照应的是前句"is"
完整的一句是:
His monthly income is at least three thousand yuan,
if it's not more than three thousand yuan.
(他的月薪如果没有超过三千元的话,至少是三千的.)
2.A
A和C都有点相似.但这里选择的是A,选择"what"
"Young people nowadays are different from what we used to be."
这里表达的是"we used to be what",故选A
