肯定句

 
来源: 考点

  • 对事物作出肯定判断的句子叫肯定句。
    对事物作出否定判断的句子叫否定句。
    结构:主语+谓语+其他 
    例:Tom played football yesterday afternoon. 汤姆昨天下午打篮球了。 
             This is my bedroom. 这是我的卧室。
  • 肯定句分类:
    A、使用“是”字句,也叫判断句。 
    B、使用一般的肯定句式。
  • 肯定句、否定句、一般疑问句和特殊疑问句的相互转换:
    1、有am, is, are的句子,
    就划线部分提问(变特殊疑问句)
    This is a book.
    第一步:变一般疑问句 Is this a book?
    第二步:找合适的特殊疑问词 Is this what ?
    第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。What is this?

    2、没有am, is, are的句子,
    肯定句变否定句:在主语后面加上do not或者does not,其余按顺序照抄动词用原形
    肯定句变一般疑问句:在句首加do或者does并大写,其余照抄。注意:动词用原形
    肯定句变特殊疑问句(就划线部分提问):分3步骤
    第一步:先变一般疑问句
    第二步:找合适的特殊疑问词代替划线部分
    第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。
    注意:一定先变一般疑问句。但是,如果问的是主语或主语的定语时,语序不变,为"特殊疑问词(+主语)+陈述句"。     

    3、划线部分不能在特殊疑问句中出现。
    非单三时用do,单三时用does
    非单三:
    肯定句:I like English.
     一般疑问句:Do you like English?
    否定句:I do not like English.
    单三 :
    肯定句:He likes English.
    一般疑问句:Does he like English?
    否定句:He does not like English.
    就划线部分提问:
    I like English.
    第一步:先变一般疑问句 Do you like English?
    第二步:找合适的特殊疑问词代替划线部分Do you like what?
    第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。What do you like?

    4、特殊:
    ①some变为any。如:
    There are some birds in the tree.→There aren't any birds in the tree.
    但是,若在表示请邀请、请求的句子中,some可以不变。如:
    Would you like some orange juice?
    与此相关的一些不定代词如something, somebody等也要进行相应变化。
    ②and变为or。如:
    I have a knife and a ruler.→I don't have a knife or a ruler.
    ③a lot of (=lots of)变为many或much。如:
    They have a lot of friends.(可数名词)→They don't have many friends.
    There is lots of orange in the bottle.(不可数名词)
    →There isn't much orange in the bottle.
    ④already变为yet。如:
    I have been there already.→I haven't been there yet.

    主谓宾:She write a leter to him.
