【題目】--You’ve made great progress in your studies of English, haven’t you?

-- Yes, but much________.

A.remains to doB.is remained to do

C.is remained to be doneD.remains to be done

【答案】D

【解析】

考查非謂語動詞。句意：—你的英語學習取得了很大的進步，是嗎？—是的，但還有很多工作要做。根據(jù)句意和結構可知remain表示“仍然”，不能用被動語態(tài)，而且much和do是被動關系，表示將要發(fā)生的事情，用不定式，因此應使用不定式的被動式。故選D。
