英语人教版七年级下册现在进行时的用法.doc

现在进行时基本用法一. 构成方法现在进行时由 am/is/are 加现在分词构成。二. 用法说明表示此时此刻或现阶段正在进行的动作。如：Theyre having a meeting. 他们在开会。Im studying at an evening school. 我在上夜校。表示计划或安排好了的将来动作，常与一个表示将来的时间状语连用。如：Mike is coming home on Thursday. 迈克星期四回来。Theyre having a party next week. 下星期他们将开一个晚会。注：表示安排将要做的事，人作主语宜用现在进行时，事物作主语，宜用一般现在时。试比较：Im not going out this evening. 今晚我不准备出去。(不宜说I dont) The concert starts at 7: 30. 音乐会七点半开始。现在进行时与always, often, forever等连用表示赞扬. 厌烦等语气。如：Youre always interrupting me! 你老打断我的话!(抱怨) My father is always losing his car keys. 我爸老丢车钥匙。(不满) Shes always helping people. 她老是帮助别人。(赞扬) 现在进行时在时间和条件状语从句中，代替过去将来时。如：He promised to buy me a computer if he got a raise. (from )注意：像 be, think, understand, love, have, own, see, hear, find, belong to 等静态动词通常不用于进行时。三. 现在进行时的肯定肯定句. 否定句. 疑问句形式：现在进行时的肯定句句型 （1）第一人称：主语 + am + 现在分词 + eg. I am watching TV. 我现在看电视。（2）第三人称单数：主语 + is + 现在分词 + eg. She is washing the dishes. 她正在洗澡。（3）第二人称及复数人称：主语 + are + 现在分词 + eg. They are playing games. 他们正在做游戏。现在进行时的否定句句型 主语 + 相应be动词 + not + 现在分词 + eg. He isnt watching TV. 他没在看电视。I am not cooking. 我没有在做饭。We arent having English class. 我们没在上英语课。现在进行时的一般疑问句句型 相应be动词 + 主语 + 现在分词 + ？eg. Are you dancing? 他们正在跳舞吗？Is he drawing a picture? 他正在画一张画吗？Are you talking with your friend? 你正和你的朋友谈话吗？现在进行一般疑问句的答语句型 （1）肯定回答：Yes, 主语 + 相应be动词。（2）否定回答：No, 主语 + 相应be动词 + not。eg. Are you listening to the music? Yes, I am. / No, I am not. 你正在听音乐吗？是的，我正在听。/ 不，我没在听。Is Aunt Wang knitting a sweater? No, she isnt. 王阿姨正织毛衣吗？不，她没有。现在进行时的特殊疑问句句型 特殊疑问词 + 相应be动词 + 主语 + 现在分词 + ？eg. What are you doing? 你正在干什么？Who is singing a song? 谁在唱歌呢？Why are they cleaning their room? 他们为什么在打扫房间？现在进行时特殊疑问句的答语回答特殊疑问时，根据不同的疑问词的情况来决定回答方式。回答what提问时，答语是现在进行时的肯定形式；回答who提问时，只需说明主语是谁，再加相应的be动词即可。eg. What is he doing? He is writing a letter. 他正在干什么？他正在写信。Who is swimming in the lake? Jim is. 谁正在湖里游泳？吉姆正在游泳。四. 动词的现在分词形式构成方法一般动词原形结尾直接在词尾加ing,如：playing, listening, cleaning等等重读闭音节单词,末尾以元音字母加一个辅音字母结尾的,双写辅音字母加ing,如:getting,beginning,putting,stopping,sitting,cutting,running,shopping,swimming,setting以不发音的字母e结尾，having, coming, writing, taking, making, arriving, living, hoping注意：（一）把动词变成现在分词形式易出错例：1. They are swiming.(swim) 2 . Jenny is plaiing(play)football.答案：1. swimming 2 .playing解析：动词变现在分词可有如下口诀:“一添一去y不变”. “一添”指双写规则；“一去”指去掉不发音字母e规则；“y不变”指要与名词变复数区分开。（二）丢掉be动词或忘记把动词变成现在分词例：1. Look, two children flying.(fly) a kite in the park. 2 . Li Ming isnt read ( not read) a book in bed now.答案：1 are flying 2 isnt reading解析:现在进行时肯定句的结构规律为: “be+现在分词,缺一不可”。这一点必须牢记。（三）对动词或动词词组提问时丢掉doing例：The students are singing in the room. (对划线部分提问) What are the students in the room?答案：What are the students doing in the room?解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?” 或简写为“What.doing.”?句式。（四）现在进行时态的选择疑问句中易忽视or后用现在分词形式例：孩子们在跑还是在跳？ Are the children running or jump?答案：Are the children running or jumping?解析: or连接的是两个并列成分，动词形式须一致。练习：（一）单选1.
