Question

【題目】—What should I do, doctor?

—_____ healthy, you should do more exercise.

A.KeepB.KeepingC.To keepD.Kept

Answer 1

【答案】C

【解析】

句意：——我該怎么辦，醫(yī)生？——為了保持健康，你應(yīng)該多做運(yùn)動(dòng)。

考查動(dòng)詞不定式。A. Keep保持，動(dòng)詞原形；B. Keeping動(dòng)名詞或現(xiàn)在分詞；C. To keep動(dòng)詞不定式；D. Kept過去式或過去分詞。根據(jù)_____ healthy, you should do more exercise. 可知這里用to引導(dǎo)的不定式短語作目的狀語，在這里表示多做運(yùn)動(dòng)的目的是保持健康，故答案選C。
