小升初专项：句型转换(重点对划线部分提问).doc

专项： 句 型 转 换
1.句子是英语学习的核心，从句子使用的目的来分，可以分为四类：1.陈述句(肯定句和否定句)，2.疑问句（一般疑问句，特殊疑问句和选择疑问句）3.祈使句（肯定句和否定句）4。感叹句。四大句型的相互转换，对于学生来讲是个难点，因此可通过说顺口溜的形式来帮助学生解决这一难题；
如：将陈述句改为一般疑问句，可以编成这样的顺口溜：疑问 疑问掉个头，be(系动词：am,is are)放在最前头；
又如：将陈述句的肯定句改为否定句，我们就可以这样说：否定 否定加not,加在何处，加在系动词的后面；
没有系动词be时，我们只需要根据动词的形式借“do ,does ,did”就可以了;
但是要记住一点：does ,did他们只喜欢动词原形，不喜欢他们带着“s,或者ed”哦！
最难的就要算‘划线部分提问’和‘看问句，写答句’这种题型了，其实我们只要掌握疑问词的具体用法，了解他们是对什么提问的，这种题型就很容易了。
疑问词 用法
What 用来问是什么，叫什么，做什么
What time 用来问时间
What color 用来问颜色
What abou 用来征求意见或者询问感受t
What day 用来询问星期几
What date 用来询问日期
When 用来问时间
Where 用来问地点
Which 用来问具体哪一个
Who 用来问人物是谁
Whose 用来问东西是谁的
Why 用来问原因
How 用来询问身体状况等
How old 用来询问年龄
How many 用来询问数量（可数名词）
How much 用来询问数量（不可数名词）和价格
How about 用来征求意见或者询问感受

2.同义句的转换很简单，只要记住同义短语就可以了；
比如：be good at=do well in;
lots of=many=a lot of;
take a walk=go for a walk;
want to =would like to;
come from =be from;
have school=go to school;
show sb sth=show sth to sb;
stay away from =keep off;
give sb sth =give sth to sb
It's time to + V原= It's time for + n.
3.单数句变为复数句也是我们经常碰到的题型，做这样的题目是首先需要知道单数名词变复数的规则哦！
比如：大部分的名词在后面加“s”；
以“s , x , ch , sh”结尾的单词后加”es”；
以辅音字母加“y”结尾的，要把”y”变为“ie”后再加“s”;
以“f , fe”结尾的单词，变“f , fe“为“ve” 后再加“s”；
以“o”结尾的单词加“es”的有句顺口溜：黑人英雄爱吃土豆西红柿和芒果；
Negro(小学阶段未出现),hero, potato ,tomato,mango.
