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。
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 sbIt'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.随堂练习1.
