This afternoon we're going to have an English class; remember _____ your book.
考查非谓语动词的用法和动词的词义辨析
remember to do sth. 意为“记住去做某事（还没做）)”；remember doing sth. 意为“记得做过某事（已做过）”。根据 "we're going to have" 可知这里表示提醒去做某事，故排除选项C。finish 意为“完成”；bring“带来”。故用 to bring 故选选项B。
用括号内所给单词的适当形式填空。
(1) In order to have a good grade,she started the(prepare) very early.
(2) Now more and more people choose to send online(invite).
(3) Her parents were busy preparing(go) on holiday.
(4) They plan to go(swim) this Sunday.
(5) I hope I will be free(do) what I like.
(1) 由句子结构及空前的 the 可知此处填名词，因此把动词 prepare 变为名词 preparation。
(2) 空前有 send，空处与 online 一起构成 send 的宾语，因此把动词 invite 变为名词 invitation，再结合语境可知应用复数形式。
(3) prepare to do sth. 意为“准备做某事”，因此此处填 to go。
(4) go swimming 意为“去游泳”。
(5) be free to do sth. 意为“随心所欲做某事”；因此此处填 to do。
— I can't find David. Where is he?
— He _____ for tomorrow's competition at home.
考查 prepare 的时态
句意：—— 我找不到戴维。他在哪？—— 他正在家准备明天的比赛。结合语境可知描述的是现在正在进行的动作，故用现在进行时态。故选选项B。
