一-现在进行时的构成(共8页).doc

精选优质文档-倾情为你奉上 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：一般情况 +ing falling 以不发音字母e结尾的单词去e, +ing   having以重读闭音节结尾的单词末尾只有一个辅音字母时.双写词尾字母+ingputting 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（看）、listen（听）来表示now（现在）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。（详见第十章将来时）    she isn't going to speak at the meeting.她不打算在会议上发言。  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。   Where are you going next week？  下周你计划去哪儿？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？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。 三 一般现在时和现在进行时的区别  1一般现在时表示经常性的动作；而现在进行时表示暂时性的动作。    He walks to work.他步行上班。（习惯、经常性的动作）    He's walking to work because his bike is being repaired. 他现在走着上班因为他的自行车正在修理。（只是暂时的情况）     Where does he live？他家住在哪儿？（询问一般的情况）Where is he living（staying）？他这几天住在哪儿？（询问暂时一段时间的情况）2现在进行时有时可用来代替一般现在时，表达说话人的某种感惰，使句子有强烈的感情色彩。常与always， forever连用。  You are always forgetting the important thing.你总是把重要的事情忘掉。（表达出不满的情绪）   Mary is doing fine work at school.玛丽在学校学习得挺不错。 四现在进行时的四种句式 （1）肯定句：be + doing如： 1.
