Question

Unit 3 is very important .Remember _______as often as possible .

A. going it over    B. to go over it    C. going it over    D. to go it over

Answer

D

【解析】

句意：第三单元是很重要的，记得尽可能经常复习。going it over复习它；to go over it复习它，动词不定式，形式不对，it应放在中间；going over it形式错误，it应位于中间；to go it over动词不定式，复习它。句中谓语动词是remember，常用于句型remember to do sth.记得去做某事；或remember doing sth.记得做过某事。根据句意可知，这里表示“记得去复习”，应用动词不定式，故选D。
