Unit7 AbilitiesGrammarII
1.了解感叹句的定义及构成；2.能理解和辨别What和Hw引导的感叹句；3.能在正确的语境中使用感叹句。
所谓感叹句，就是用来表达喜怒哀乐等强烈感情的句子。感叹句一般由what或hw开头，句末加感叹“！”。What：中心词是名词。Hw： 中心词是形容词、副词。
Self-learning：感叹句概念
e.g. What a lvely girl she is!
What an easy questin it is!
e.g. What interesting films they are!
(1) what + a/an + 形容词 + 可数名词单数 （+ 主语 + 谓语）!
(2) what + 形容词 + 可数名词复数/不可数名词 (主语 + 谓语）!
A: What引导的感叹句
What imprtant news it is!
e.g. Hw heavy the rain is!
e.g. Hw quickly the by runs!
(1) Hw + 形容词 (+ 主语 + 连系动词)!
(2) Hw + 副词 (+ 主语 + 行为动词)！
B: Hw引导的感叹句
怎样将一个陈述句改成感叹句呢
(3) Hw + 主语 + 谓语！
e.g. Hw time flies!时间过得真快呀！
1.一分；2.二加；3.三换位；4.四去掉。 第一步：一分在谓语动词后划一双竖线,使句子分为两部如：He is a very hnest by.他是个诚实的孩子。Li Lei wrks very hard.李雷学习很刻苦。
Explratin：陈述句变为感叹句的方法
第二步：二加 如果第二部分的中心词是名词，就加上what； 如果是形容词或副词，就加上hw. 如： He is ‖ a very hnest by. Li Lei wrks ‖ very hard. He is ‖(what) a very hnest by. Li Lei wrks‖(hw) very hard. 第三步：三换位 把 ‖两边互换位置，句号换位感叹号。如：
What a very hnest by he is! Hw very hard Li Lei wrks!
第四步：四去掉原陈述句中含有very, t等程度副词时，在变成感叹句时要去掉。 即:
What an hnest by he is! Hw hard Li Lei wrks!
Practice: Let’s have a try!1.It is a sunny day. 2. Li lei runs very studies very hard in ur schl.
What a sunny day it is!
Hw fast Li lei runs!
Hw hard he studies in ur schl!
4. They are interesting bks. (改感叹句) _______ __________ ______ ______ ______
What interesting bks they are!
=________ _______ the bks ________!
eg: 1. Hw interesting the by is ! _____ _____ interesting by he is！
Think abut: What 与Hw 同义句转换
解题思路：首先,要记得:感叹句由Hw或者What引导，其次,要分析:如果所给题由Hw引导，那它的同义句 就应该由What引导;反之一样，即： 如果所给题由What引导,那它的同义句 就应该由Hw引导最 后，如果是可数名词单数就在形容词前加上 冠词a或者an ,否则不用。

Summary: What did we learn in this lessn?
1.感叹句的定义：表示说话时喜怒哀乐等强烈感情的句子叫感叹句。感叹句句末常用感叹号。
2.以what引导的感叹句的结构：
3. Hw+形容词或副词+主语+谓语!
①What+ a/an+形容词+可数名词单数+主语+谓语！ ②What+ 形容词+可数名词复数+主语+谓语！ ③What+ 形容词+不可数名词+主语+谓语!
（1）感叹句中的主语、谓语通常可以同时省略。 e.g .What a nice girl（she is）! 多好的女孩啊！ What bad news（it is）! 多坏的 Hw handsme（he is）!　真英俊！ What a nice cat（it is）！多美的大衣！（2）感叹句除了上述的what, hw引导之外， 也可以用单词、短语或句子加感叹号构成。 e.g. Wnderful！精彩！ Gd luck！祝你好运！ The bk is s interesting！这本书真有趣！ The dr pened!

Exercises in class
用Hw , What (a / an) 填空
感叹句选择What / Hw 的技巧:1：从后往前看；2：选择What/ Hw 的关键主要看主语前面 的关键词，与其他时间、地点等无关；如果是单数名词就选What a/an;如果是复数名词/不可数名词就选What;如果是副词/形容词就选Hw;
1.______a heavy bx it is ! 2. ______heavy the bx is !3. _____ wnderful the film is ! 4. ______ a wnderful film it is!5 _______gd time they had tday!6.______beautiful the flwers are!7______beautiful flwers they are!.
