七年级仁爱版句型转换专项练习-

1、七年级仁爱版句型转换专项练习:句型转换专练一、由肯定句变为一般疑问句1、谓语动词是be动词时,把be动词提前放句首大写,其他成分可照搬不动。(注:在肯定句和一般疑问句中主语的一、二人称要互换。2、谓语动词中如果有情态动词,则把情态动词提前放句首大写,其他成分可照搬不动。(注:在肯定句和一般疑问句中主语的一、二人称要互换。3、谓语动词是行为动词的一般现在时或一般过去时,在改为一般疑问句的时候,根据主语的人称和单、复数,需要借助助动词do、does或did ,把助动词放句首大写,其他成分位置可不懂,有了助动词,动词就要用原形。二、由肯定句变为否定句肯定句变否定句一定要加not。谓语动词是be动词时

2、或情态动词时,直接在be动词、情态动词后not 。除了be动词的am外,否定词not都可以和前面的be动词或情态动词缩写。如果谓语动词是行为动词的一般现在时或一般过去时,则要在动词前加助动词do、does 或did,再在其后添加否定词not,分别可以缩写为don't、doesn't和didn't ,有了助动词,动词就要用原形。下面几种句型在变为否定句时情况特殊一些,做题时须引起注意:(1 think + 宾语从句,变否定时,not放在主句上,即:I don't think + 宾语从句。eg. I think it will rain tomorrow . I

3、don't think it will rain tomorrow .(2 祈使句没有主语,以动词原形开头。变为否定时,在动词原形之前添加助动词don't . eg. (1 Water the flowers . Don't water the flowers .(2 Please clean the blackboard . Please don't clean the blackboard .三、句子的单复数互换对应句中的名词、代词、动词等,能变则变,不能变的,要么保留,要么去掉。要求必须掌握名词的单复数的变化规则,代词对应的人称和单复数,动词的第三人称单数

4、的变化规则等。具体情况具体对待。(1 The girl is from England . The girls are from England .(2 He is a polite and helpful boy . They are polite and helpful boys .上述例句中,划线的为能变的,没划线的为该保留的,a(an为该去掉的。反之,在由复数变为单数时,则要根据句意在名词之前补上一个a (an。eg. They are English girls . She is an English girl.但是对于"There be"句型,单复数转换时句中的

5、 a / an不能去掉,而要根据句式将其与some或any 互换。eg. (1 There is a boat on the lake . There are some boats on the lake .(2There isn't a tree behind the house . There aren't any trees behind the house .(3 Is there a pet dog in your home ? Are there any pet dogs in your home ?(4 There aren't any pictures
