语法现在进行时 定义:现在进行时是表示现在、说话瞬间或在当前一直正在做着的动作。一、现在进行时的构成:am/is/ are+ v-ing 是现在进行时的构成形式v-ing 现在分词的构成: 构成法例词一般加-ingwork - working以 e 结尾的词去 e 后加-inglive - living以重读闭音节或 r 音节结尾,末尾只 有一个辅音字母的词,要双写这个辅 音字母,再加-ingstop - stopping run - running refer - referring swim - swimming以 ie 结尾的重读开音节的词,改 ie 为 y, 再加ingdie - dying tie - tying以 y 结尾的动词变为现在分词,y 不 变,直接加上ingplay - playing study - studying1、进行时的肯定句:主语+ be(am, is, are)+现在分词+其他如:We are studying English now. 2、进行时的否定句:主语+ be not +现在分词+其他.如:She isnt reading now. 3、现在进行时的疑问句: .现在进行时的一般疑问句: 1句型:Is(Are) +主语+现在分词+其他?如:Are they playing tennis now?肯定回答:Yes, 主语+ be 动词. 否定回答:No, 主语+be 动词+ not. Steve is talking to his science teacher. 变疑问句:The children are eating some apples at home. 变疑问句:.现在进行时的特殊疑问句: 2句型:特殊疑问词+ is/are +主语+现在分词+其他?如:- What are you studying?- Im studying English.对划线部分提问: Jim and his sister are eating dinner at their uncles home.二、现在进行时的基本用法 1、表示说话时正在进行的动作常和 now 连用,有时用一个动词如 look、listen 来表示 now 这一时间概念。Look!A train is coming.看!火车来了Listen!He is playing the piano.听!他在弹钢琴。 2、表示现阶段正在进行着的动作但不一定是说话时正在进行。常和 at present(目前) 、this week(本周) 、 these days(这几天)等时间状语连用。What lesson are you studying this week?你们本周学哪一课了?(说话时并 不在学) 3、现在进行时有时可用来表示一个在最近按计划或安排要进行的动作,即是说 可以用来代替将来时,但此时,一般要与表示将来的时间状语连用,而且仅 限于少量动词。如:go(去) 、come(来) 、leave(离开) 、start(开始) 、arrive(到达) 、 return (返回) 、sleep(睡觉) 、Are you going to Tianjing tomorrow?你明天去天津吗?How many of you are Coming to the party next week? 你们有多少人下周要来参加晚会? 4、be going to+动词原形这一句型表示即将发生的事或打算(准备)做的事,我们把它归在将来时里 了。 如:she is going to speak at the meeting.她打算在会议上发言。注意:如果没有表示将来时间的状语,此类句子就可能指现在或现阶段的动 作。请比较下面两个句子的区别:Where are you going next week?下周你计划去哪儿? 1用现在进行时表示将来时,因为有 next week(下周)这一时间状语。Where are you going?你现在去哪儿? 2因为没有表示将来时的时间状语,所以就按句型来翻译,即现在进行时。随堂练习:一、写出下列动词的现在分词形式: 1. work _ sing_ play_ study_ 2. dance _ come_ write_ take_ 二用动词的适当形式填空: 1.He _ (be) drinking water now. 2.
