高考英语一轮总复习优化课件(江苏专用)七、时态和语态(牛津译林版)
解析：选D。考查时态。答句中的then 指代的是at five tomorrow afternoon， 此处意为“明天下午五点那个时候他 将正在开会”，故应用将来进行时。
要点浓缩 1．现在进行时 现在进行时表示说话时正在发生着的 一个动作；表示现阶段但不一定是发 生在讲话时的一个动作；表近期特定 的安排或计划；go，come等表示起止
(2)be going to表示将来的情况。人作 主语时表示打算做某事；物作主语时 表示客观迹象表明马上要发生的动作 或存在的状态。 Look at the sky.It looks as if it is going to rain.看看天空，看起来快要下雨 了。(客观迹象表明要发生的动作)
2．将来时用于特殊句式 祈使句＋and/or...将来时句子。 Put everything where they were before or the librarian will punish you. 把东西放在原来的位置否则图书管理员 会惩罚你。
B．don’t；would
C．don’t；will
D．didn’t；will
解析：选 D 。第一空的“不知道”应该 是过去不知道，现在已经知道了，要用 一般过去时。be going to和will都可以表
示将要发生的动作，be going to往往表示
事先已计划或思考过的事情，而will常表
示临时作出的决定，因此选D。
A．has played
C．plays
B．played
D．is playing
解析：选D。句意：那首音乐听起来
十分熟悉。谁在楼上弹钢琴？本题考
查时态。根据句意可知，本句说的是
现在的事情且动作尚未完成，故用现
