Unit 3. I’m more outgoing than my sister.
形容词（adj.）和副词（adv.）的比较级、最高级
大多数形容词和副词有三个等级：
原级（不作比较），修饰词very, so, too, pretty, really；
比较级，表示“较……”或“更……”的意思（两者之间进行比较）, 标志词than , A or B, of the two, 修饰词much, a lot, a little；
Eg. Sam is taller than John.
Which story is more interesting, this one or that one?
Tom is the taller of the two boys. 汤姆是两个男孩中较高的那个。
最高级，表示“最……”的意思（三者或三者以上作比较），形容词最高级前面一般要加定冠词the，后面可带in（of）短语来什么比较的范围。

比较级的用法：1）比较级常常用than来连接被比较的两个人或事物。
Eg. Li Lei is taller than Wang Jun.
Her room is bigger than mine .
My classmate is fatter than me.　　
比较级+and +比较级,表示“越来越…”　　The days are getting longer and longer in summer.3）the+比较级…,the+比较级….表示“越…就越…”　　The harder you work, the better you will learn.4) the+比较级+of the two表示“两者中较…的那个人或物”时，在比较级前
加定冠词the。　Eg. He is the taller of the two. 他是两人中较高的那个。
◇比较级前可以有一个表示程度的状语，最常见的三大修饰词是：a little,
much,even。　　My sister is a little taller than me. 姐姐比我高一点。　　Their house is much larger than ours. 他们的房子比我们的大很多。◇比较应在同类事物之间进行。　误：Your English is better than me.　正：Your English is better than mine. 你的英语比我的好。◇为避免重复，我们通常用that, those, one, ones代替前面出现的名词。
that代替可数名词单数和不可数名词，those代替可数名词复数。one既可指
人又可指物，只能代替可数名词。
　E.g. The book on the table is more interesting than that(或the one)on the sofa.
桌上的那本书比沙发上的那本要有趣些。　 A box made of steel is stronger than one made of wood.
钢制的盒子比木制的盒子要坚固些。

十四．反意疑问句 概念：反义疑问句即附加疑问句。它表示提问人的看法，没有把握,需要对方证实。（所以本质上概念：反义疑问句即附加疑问句。它表示提问人的看法，没有把握,需要对方证实。（所以本质上反义疑问句也是问句，并且回答和一般疑问句相似，即用yes/no 回答）

速记方法:前肯后否，前否后肯；前be后be，前无be后助，时态一致。

反义疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句，两部分的人称时态应保持一致。
陈述部分肯定式+疑问部分否定式
Eg. They work hard, don’t they?
She was ill yesterday, wasn’t she?
2．陈述部分否定式+疑问部分肯定式
Eg. You didn’t go, did you?
He can’t ride a bike, can he?

请注意以下句型的反义疑问句的用法：

1.当陈述部分的主语是I ，后面的疑问句用：aren't I?
Eg. I am a student, aren’t I ?
2. 陈述句如果是there be 结构时，疑问部分仍用there。
Eg. There once was a man named Saint Nicholas, wasn't there?
3. 陈述部分的主语是this, that时，疑问部分的主语多用it；陈述部分的主语是these, those时，疑问部分的主语多用they。
Eg. This is a dictionary, isn't it?
Those are shelves, aren't they?
4. 陈述句中含有no,never,few,little, seldom,hardly等具有否定意义的词时，疑问部分常用肯定形式。
Eg. Tom has never been to England, has he?
He can hardly swim, can he?
There are few apples in the basket, are there?
但陈述句中如果有否定意义的前缀和后缀的单词时，整个句子仍视为肯定句，反意疑问部分多用否定形式。
Eg. She is unhappy, isn't she?
5.当陈述部分是I think 加从句时，疑问句应和从句的人称时态保持一致。
Eg. I think chickens can swim, can’t they?
I think Lucy is a good girl, isn’t she?
I didn't think he was happy, was he?
6. 陈述句的主语是nobody,everyone,somebody等指人的不定代词时，反意疑问部分的主语多用they。
如果陈述句的主语是something,nothing,anything,everything等指物的不定代词时，反意疑问部分的主语多用it。
Eg. Nobody says a word about the accident, do they?
对这个事故没人说什么，是吗？
Everything seems all right, doesn't it? 看起来一切顺利，是吗?

以let's开头的祈使句的反意疑问句部分要用shall we。
以 let me或let us 开头的祈使句反意疑问部分要用will you。
其他行为动词引起的祈使句，反意疑问部分都要用will you.
Eg. Let's go for a walk, shall we?
Let us go our for a walk, will you?
Let me tell you the truth, will you?
Don't speak, will you?
8.陈述部分有had better 时，疑问句应用hadn’t开头：
Eg. You’d better get up early, hadn’t you?
9. 陈述部分有情态动词must，问句有2种情况：
(1) mustn't表示“禁止，不可”时，附加问句通常要用must.
Eg. You mustn't stop your car here,must you?你不能把车停在这地方，知道吗？
(2)must表示“有必要”时，附加问句通常要用needn't.
Eg. They must finish the work today,needn't they? 他们今天要完成这工作,是吗？

反义疑问句的回答用yes,no, 但是，当陈述部分是否定形式时，回答要按事实。
Eg. They don’t work hard, do they? 他们不太努力工作，是吗？
---Yes, they do. 不，他们工作努力。
---No, they don’t. 对，他们工作不努力。
