初中现在进行时讲解练习及答案.doc

1） 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+ing
putting
什么是音节？闭音节？重读闭音节？ 1，英语单词是由字母组成的，字母构成音节。一般来讲有一个元音就是一个音节。含一个元音的词叫作单音节词，含两个或两个以上元音的单词叫作双音节或多音节词。单音节词都是重读音节，双音节和多音节词中一般有一个重读音节，其他的是弱读音节。2，闭音节：闭音节是两个辅音中间有一个元音的音节。例如：not，thank，ten，am，six等。 3，重读闭音节是需要重读的闭音节，如果是单音节一定重读，但是重读符号省略;如果是多音节，一定有一个需要重读。重读闭音节（辅音1+元音+辅音2）中的辅音2在构词法中要双写，如果不重读，如listen中的第二个音节ten(闭音节)中的n就不用双写，因为重读在第一个音节lis上
有一些特殊变化(或者说以Ie为结尾的重读闭音节的动词)的现在分词〔有3个〕,:lying—lie, dying ―die tying―tie 这些以ie结尾要去e再把I变y再加ing．
　　2) 现在进行时的基本用法
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。
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）
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？
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。
一般现在时和现在进行时的区别
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）
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。
