怎样改感叹句
把陈述句改为感叹句是同学们应掌握的一项基本功；但由于有些同学未曾掌握其变化方法，在做这种题目时常会出错。如：
he is a very good teacher．
→how a very good teacher he is！
→what a very good teacher he is！
they are working hard to make their school more beautiful．
→what hard they are to make their school more beautiful！
→how hard to make their school more beautiful they are work-ing！
那么，采用什么方法才能保证把陈述句变为感叹句时不出错呢？请记住：
一断→二加→三前移，强调副词要删去。
名词前面用 what，形、副用 how 莫迟疑。具体地说就是：
一断：把要进行强调的部分从句中断开。
he is // a very good teacher．
they are working // hard // to make their school more beautiful．
二加：在句末加感叹号；在被强调部分前加强调词。若被强调的中心词是名词则用 what，若被强调的中心词是形容词或副词则用 how。
he is // what a very good teacher！
they are working // how hard // to make their school more beau-tiful！
三前移：即把被强调的部分移到句首。
what a very good teacher he is！
how hard they are working to make their schoolmore beautiful！
强调副词要删去：把被强调部分中原有的 very，quite 等词删去。
what a good teacher he is！
exercise：
试用上面介绍的方法将下列句子变成感叹句。
1．he dances well．
2．the children live a happy life．
3．this room is very clean．
4．the workers can make wonderful machines．
key：1．how well he dances！
2．what a happy life the children live！
3．how clean this room is！
4．what wonderful machines the workers can make！
