Question

【題目】—They finally get the prize.

—So they do. They have spent as much time as they can ________ it.

A.practiceB.practicingC.to practice

Answer 1

【答案】B

【解析】

句意：——他們終于得獎(jiǎng)了。——確實(shí)如此。他們已經(jīng)花了盡可能多的時(shí)間來練習(xí)。

考查動(dòng)詞形式辨析。practice練習(xí)，practicing是現(xiàn)在分詞結(jié)構(gòu)；to practice是不定式結(jié)構(gòu)。spend time doing sth.花費(fèi)時(shí)間做某事，固定結(jié)構(gòu)；根據(jù)句意結(jié)構(gòu)，可知選B。
