I know the importance of the math test. It 30% of the final exam.

A. makes of

B. makes into

C. makes up

D. makes from

答案：

A. makes of

B. makes into

(答案→)C. makes up

D. makes from

解析：句意：我知道数学考试的重要性。它占到了期终考试的30%。make up表示“占据，占多大比重”；make of表示“由什么构成，多用于被动结构”；make up表示“化妆，编造”；make from表示“有什么制造，多用于被动”；故选C。
