The comparative of adjective语法专讲英语中，为了表现不同程度的性质，大多数形容词都有三个等级，即：原级、比较级和最高级。要比较两个人或事物，就会用到比较级。注：形容词和副词的原级就是原形。When we compare two people or things, we can use the comparative of adjectives. we form the comparative of adjectives like this: Work out the rule To form the comparative of adjectives , we often add ______to short adjectives and use ________with long adjectives
We often use ________after the comparative of adjectives.ermorethan 形容词比较级的构成规则：The water in Glass 1 is colder than Glass 2.The weather of Xiamen is hotter than the weather of Hangzhou.1.A…+比较级+than+B两者进行比较,表示“一方比另一方更……” 形容词比较级的用法：2.Who/Which is + 比较级，A or B?Mary is the taller of the twins.Which box is bigger, this one
or that one?Who is taller,Merry or Mary?The green box is the bigger of the two.3.比较级中的: 越来越…比较级+and+比较级 hot1.It’s getting hotter and hotter in summer.
2.English is more and more useful.The higher, the more dangerous.越…就越…
the +比较级，the +比较级中考链接(2017. 四川遂宁)—How do you improve you English?
—__________ you speak, __________ your English will be.
A. The less; the more B. The more; the better
C. The less; the better D. The more; the less
【解析】考查比较级的用法。句意：—你怎样提高你的英语？ —_____你说，_____你的英语将会。众所周知，英语说得越多，提高越快，故选B。1.形容词和副词的比较级可以单独使用。
e.g. Are you feeling better today?
Try to do better next time.
2.比较级前可加even(更加)much(……得多)，
far(……得多)a little(……一点)a bit(一点)，
a lot(大量)still(还，还要)或倍数表示比较的程度。
注意: 比较级不能用very, so, too, quite等修饰。
e.g. The jacket is a little / much cheaper than the sweater.
Can you speak a lot more loudly? 注意：中考链接(2017·湖南永州) —Why do many people buy things online on Nov. 11th?
—Because there are so many sales, and the prices are ______.
A. much lower B. more cheap
C. more expensive
【解析】考查形容词比较级辨析。句意：——为什么11月11日那天很多人在网上买东西呢？——因为有如此多的折扣，并且价格是______.根据语境知，本句应是更便宜，故选A。GrammarSubject + Vt. + Object + Object complementFunctionsGrammar:Look and learn:在复合句中，用一个句子充当主句中动词的宾语, 这个从句就是【宾语从句】.1. I’m sure that shopping online is a little cheaper.
2. I’m not sure whether the things are good or not.
3. A reporter said that scientist could put little computers right into our head.
4. The teacher asked if there were any good websites for teachers.观察以下句子结构上有什么共同特点：主句连接词从句连接主句和从句的词
叫连接词或引导词Grammar:Look and learn:A: Scientist can put little computers right into our head.B: A reporter said that scientist could put little computers right into our head.A: Are there any good websites for teachers?B: The teacher asked if there were some good websites for teachers.某人直接说出的话叫直接引语，而通过另一个人来转述别人所说的话
叫间接引语，间接引语常用宾语从句结构。直接引语间接引语直接引语间接引语请观察一下直接引语变成间接引语后
句子有哪些变化？Presentation:直接引语如何变成间接引语:1. 连接词
1)当由陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：
He said: “I could finish the work before supper.”(改为间接引语)
→He said that he could finish the work before supper.
2)当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如：
“Does he still live here? (用I don’t know改为间接引语)
→I don't know if /whether he still lives here.
3)如果宾语从句原来是特殊疑问句，只需用原来的特殊疑问词引导。如：
“Why are you in the classroom?” (用He asked me改为间接引语)
→He asked me why I was in the classroom.Presentation:直接引语如何变成间接引语:2. 语序 宾语从句的语序为陈述句语序，即“主语+谓语+宾语+其他”。也就是说，将疑问句转化成宾语从句时，一定要将疑问句语序转变成陈述句语序。如：
“What will he do tomorrow?” Can you tell me?(合并为一句) → Can you tell me what he will do tomorrow? 3. 时态 主句为一般现在时态，则宾语从句根据实际情况用任意的时态；但主句为一般过去时态时，宾语从句则要用过去的相对应的某种时态。例如：
“She will come by bus”, she tells me. → She tells me that she will come by bus. “She will come by bus”, she told me.
→ She told me that she would come by bus. Presentation:直接引语如何变成间接引语:4. 人称
从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。如：
“Can I use your knife?” He asked me.
→He asked me if he could use my knife.
“Do you know her telephone number?” He asked me.
→He asked me if I know her telephone number.5. 标点符号
宾语从句的标点均由主句决定。主句是陈述句，用句号；主句是疑问句，用问号。如：
Who will give us a talk? I don’t know.
→I don’t know who will give us a talk.
Do you know? Where does he live?
→Do you know where he lives?Work in groups, Make sentences based on the information in the chart like this . photoMars birdsscientistsheadsmoviePractice:A: What did Jane do
