Question

【題目】Eighty percent of the students in this school ________ three to five times a week.

A. exercisesB. exerciseC. exercising

Answer 1

【答案】B

【解析】

句意“在我們學(xué)校80%的學(xué)生一周鍛煉三到五次”。根據(jù)three to five times a week“一周三到五次”可知，用一般現(xiàn)在時(shí)，排除C；“分?jǐn)?shù)或者百分?jǐn)?shù)+of+名詞”作主語，謂語與of后的名詞保持一致，即與students保持一致，students為復(fù)數(shù)，故選B。
