仁爱：初一英语句型转换专练

 

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 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 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 .

(2)There 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 on the wall of our classroom .

 → There isn't  a  picture on the wall of our classroom .

四、同义句转换 （词汇的同义转换、句型的同义转换）

五、对句中的划线部分提问

 1、首先根据划线部分确定疑问词，将疑问词放句首大写。

主要的疑问词有：what , who , when , whose , where , why , which , how , how old , how many , how much , how long , how often , how soon , how far等。

what :用来询问事物、人的姓名和职业。另外，和不同的词一起使用还可询问具体的方面， 如what time 询问时间，what colour 询问颜色等。

who :用来询问人，尤其指人与人之间的关系。whose :用来询问归属，即和人之间的所有关系。when :用来询问时间，一般指较大的时间范围。（小范围的时间可用what time ）

where :用来询问地点。which :用来询问哪一个，主要针对名词的定语提问。

why :用来询问原因，标志是because . how :用来询问方式、程度。

how old :用来询问年龄。how many 用来询问可数名词的数量，其后要接名词的复数形式。

how much :用来询问不可数名词的数量，其后要接不可数名词。如单独使用则表示询问多少钱或对事物了解或喜欢的程度。how long :用来询问事物的长度，也可询问时间长度。

how often :用来询问某件事或某个动作在一定的时间范围内重复发生的次数，即频度。

how soon :用来询问某件事或某个动作从说话时候起要过多久才会发生，即询问将来的情况，一般与将来时态连用。how far :用来询问空间距离。

2、把原句变为一般疑问句。

3、划线部分省略。

注：如果句中的划线部分是主语或主语的定语，则可用疑问词直接替换而不用一般疑问句的语序。

eg.1、The boy on the yellow bike is Lucy's brother .

本句中的划线部分on the yellow bike 在句中作主语The boy 的定语，限定是哪一个男孩，因而确定的疑问词是which, 直接替换后的句子为： Which  boy is Lucy's brother ?
