unit 7 its raining语法攻关语法总动员重温现在进行时上个单元我们已经学习了现在进行时，今天我们来重温一下它的用法。nancy is doing her homework. 南希正在做作业。nancy isnt doing her homework. 南希没有在做作业。 is nancy doing her homework? 南希在做作业吗？ yes, she is./ no, she isnt. 是的，她在做作业。/不，她不在做作业。 现在进行时的各种句式结构归纳如下：句式结构肯定句主语+am/is/are+动词ing形式+其他否定句主语+am/is/are+not+动词ing形式+其他一般疑问句am/is/are+主语+动词ing形式+其他？肯定回答yes, 主语+am/is/are.否定回答no, 主语+am/is/are not.特殊疑问句疑问词+am/is/are +主语+动词ing形式+其他？现在进行时的“三个误区” 下列各句均有一处错误，请找出并改正。1. listen! betty sings a song in her room. _2. tony reads a book these days. _3. jim is stand on the great wall now. _4. look! mary eating an apple. _5. tom and mike are shoping for tennis rackets. _6. im writeing a postcard to my father. _1. 时态意义不理解现在进行时表示现在(说话时)正在进行或发生的动作，常与look, listen, now等标志词连用，不能和一般现在时混为一谈。病句1便属于这种错误，应将sings改为is singing。现在进行时也可以表示当前一段时间内的活动或现阶段正在进行的动作，其时间状语常为当前的一段时间，如these days, this week, from monday to friday 等。病句2属于这种错误，应将reads改为is reading。2. 谓语不正确现在进行时的谓语由“be动词+动词-ing形式”构成。be动词的形式应由主语的人称和数来决定。应特别注意：一不能丢掉be，二不能丢掉动词后的-ing。病句3、4属于这种错误，应将stand改为standing；在eating前加is。3. 现在分词构成不正确大多数动词的现在分词形式在词尾加-ing, 如telltelling; 以不发音的字母e结尾的动词，要先去掉e, 再加-ing，如closeclosing; 以重读闭音节结尾的动词，且末尾只有一个辅音字母，则先双写这个辅音字母，再加-ing，如sitsitting。病句5、6属于这种错误，应将shoping改为shopping；将writeing改为writing。中考真题()1. look, some people _ photos on the beach.(12怀化)a. took b. takes c. are taking ()2. hello, mary! this is john. you must know why i _ you. oh, hello, john! ive waited for this call since last month.(12江西)a. called b. am calling c. was calling d. have called跟踪练习按要求完成下列句子。1. i have breakfast at seven every day.
