语法一: 大数的表达法
1000以上的基数词的表示法：先从右至左数，每三位数加一个小逗点（以此把数目分为若干段）。第一个逗点前的数为thousand（千）,第二个为million（百万）,第三个为billion（十亿）

读一读：
1，234，567，890
用英语表达下列数字：
1,234
4,567,809
5,678,120,567
练一练:
1. How do you read 4，444，444 in English ?
Four millions, four hundreds and forty-four thousand, four hundreds and forty-four
B. Four million, four hundred forty-four thousand, four hundred forty-four
C. Four, four four four, four four four
D. Four million, four hundred and forty-four thousand, four hundred and forty-four

D

注意：1. 英语没有“万”这个单位，要表示“万”须借用 thousand，
如“ー万”用“十个千”表示（ ten thousand），
“十万”用“百个千”表示（ one hundred thousand）
2. 在 hundred后通常加上连词and。若读数中没有 hundred，则在 thousand后加and。1,025
3. 数字中间的点对应英语point，后面的数字一个一个读
8,844.43
one thousand and twenty five
eight thousand eight hundred and forty-four point four three
语法二:度量的表达：

英语表示“有多长（宽，高…）”时，一般将数词和长度单位(meter, kilometer, mile, feet, inch )放在表示长、宽、高，深的形容词前面。

结构：数词+单位+长宽高深的形容词
例：1.It’s 8,844.43 meters high.
2. The basketball player is 2 meters tall.
3. The river is only 2 meters deep/wide.
4. The tree is 2 meters tall.
语法三: 形容词和副词的用法
形容词和副词有三个等级：
原级
比较级
最高级
（一）原级句型：
1. as...as，表示 “和...一样…”
(A+ be动词/实义动词 +as+adj/adv原级+ as+ B )
eg: He is as tall as me.
He studies as hard as me.
2.not as/so...as...，表示“不如..…”
eg: He is not as careful as me.
He doesn’t work as hard as me.
He can't dance as well as me.

注意：只能修饰原级的词有: very，quite，pretty, so，too，
enough 等
（二）比较级的句型：
1.A + be动词/实义动词+形容词/副词的比较级+than+B 表示“A 比B更...”
Tom is smarter than Kate. He gets up earlier than Kate.
2.比较级+ and+比较级 “越来越”
He is getting taller and taller.
Our hometown is becoming more and more beautiful.
3.the + 比较级，the+比较级 “越...越...”
The more careful you are, the fewer mistakes you will make.
4.特殊疑问词+形容词比较级，A or B？
Which is bigger, the earth or the moon?
比较级修饰词有：
much, a lot, a little, a bit, far，even, still 等。
（三）最高级的用法和句式:


用法：三者或三者以上的人或物进行比较时，用最高级形式。
形容词最高级前通常需加定冠词the，句末常接in/of短语来表示范围。
(of短语所指的范围通常是一群人或 一些事物，in短语所指的范围通常是
一个场所或单位)。
例：1.他是所有男孩中最强壮的一个。
He is the strongest of all the boys.
2.他是我们班里身体最强壮的。
He is the strongest in our class.

特殊句式：
1. one of+ the +形容词最高级+可数名词的复数
“最……的……之一”。
译：电脑是最有用的发明之一。
The computer is one of the most helpful inventions.
2. the+序数词+形容词最高级+可数名词的单数形式
“第几最……”
译：黄河是中国第二长河。
The Yellow River is the second longest river in China.


（四）最高级与比较级之间的转换：
形容词与副词的最高级可与“比较级+than + any other
+单数名词”或“比较级+than + the other +复数名词”进行互换。
Tom is the tallest in his class.
= Tom is taller than any other student in the class.
= Tom is taller than the other students in the class.
比较级和最高级的规则变化：
单音节词和部分双音节词 一般直接加-er,-est tall-taller-tallest
fast-faster-fastest
以不发音的e结尾的词，直接加-r,-st nice-nicer-nicest
late-later-latest
辅音字母+y,改y为i，再加er,est easy-easier-easiest
early-earlier-earliest
重读闭音节结尾，词尾只有一个辅音字母的，双写辅音字母，加er,est. big-bigger-biggest
hot-hotter-hottest
(thin,fat,red wet)
多音节词和部分双音节词 在词前加more或most difficult-more difficult
-most difficult
carefully-more carefully
-most carefully
不规则变化
good/well --better –best
bad/badly/ill—worse—worst
many/much—more—most
little—less—least
far--farther—farthest
far—further—furthest
old—older/elder—oldest/eldest
