Question

【題目】Mary is never late for class. She always arrives there .

A.in timeB.on time

C.at a timeD.from time to time

Answer 1

【答案】B

【解析】

句意：瑪麗上課從不遲到。她總是按時(shí)到達(dá)那里。

考查介詞短語(yǔ)。in time及時(shí)；on time按時(shí)；at a time每次；from time to time有時(shí)、不時(shí)。根據(jù)Mary is never late for class. 瑪麗上課從不遲到，可知她總是按時(shí)到達(dá)那里，所以on time按時(shí)，符合題意，故答案選B。
