(一)数词 Numeral
数词是用来表示事物的数目和顺序的词。
数词的分类：1.基数词2.序数词3.分数词今天我们先来学习一下基数词。
1. 复习1—100以内的所有数字。2. 掌握百、千、万、十万、百万的表达法。
ne 1 tw 2 three 3 fur 4 five 5
six 6 seven 7 eight 8 nine 9 ten 10
eleven 11 twelve 12 thirteen 13 furteen 14
fifteen 15 sixteen 16 seventeen 17 eighteen 18 nineteen 19
2、20—90等十位数
twenty 20thirty 30frty 40fifty 50sixty 60seventy 70eighty 80ninety 90
twenty-ne 21 twenty-tw 22 ………………其它的十位数照此类推，如： thirty-ne 31 frty-tw 42 seventy-five 75 ninety-six 96
百 hundred 100 ne hundred 200 tw hundred 以此类推···· 千 thusand 1 000 ne thusand 2 000 tw thusand·········英语里没有“万”这一单位，万也用thusand表示。如：10 000 ten thusand 一万20 000 twenty thusand 两万·····
十万的说法是： 100.000 a (ne) hundred thusand 200.000 tw hundred thusand millin 百万 a (ne) millin 1,000,000 tw millin 2,000,000 ········以此类推 ······ 8,000,000 eight millin

The prject lasted 5 years and cst 2 billin dllars.2. The Chinese have been making paper fr tw thusand years.3. One thusand punds is a lt f mney.
表示确定数量时 用基数词+ hundred，thusand，millin，billin
three hundred and eighty-nine
fur hundred and fifty-seven
eight hundred and ninety
six hundred and eight
1）101~999的三位数由“百位数＋and+两位数组成”。 如：325—three hundred and twenty-five
102 ne hundred and tw
635 six hundred and thirty-five
2)三位数以上的数，从个位往前数，每三位数加一个逗号，从后往前数的第一个逗号代表thusand, 第二个逗号代表millin, 第三个逗号是billin，注意这几个词不能用复数形式，后也不能加and。例如： 2,648 tw thusand, six hundred and frty-eight 16,250,064 sixteen millin, tw hundred and fifty thusand, sixty-fur
确切数目与不确切数目的表达：hundred, thusand, millin, billin等前面有基数词，表示确切数目时，用单数，后直接接复数名词；如：three hundred bks ne hundred peple five thusand students seven millin starts
表示不确切数目时，这类词后加-s且与f连 用。如： hundreds f peple thusands f students millins f birds billins f lins注意：这类短语中，名词前如有定冠词、指 示代词或形容词性物主代词时，可加f, 但 表示的是范围。如：tw hundred f the wrkers工人中的二百（人）
(二)形容词的比较级和最高级 cmparatives and superlatives with adj. and adv.
delicius – mre delicius interesting – mre interesting imprtant— mre imprtant carefully---mre carefully quickly---mre quickly slwly---mre slwlyeasily--- mre easily
大多数形容词和副词有三个等级：原级、比较级、最高级。一、形容词比较级的构成 1.构成的不规则变化: 2.构成的规则变化:
形容词和副词的比较级
1. 构成的不规则变化:e.g. gd / well – better – best bad / badly – wrse – wrst many / much – mre – mst little – less – least far – farther / further – farthest/ furthest
2. 构成的规则变化:1) 单音节词和少数双音节词一般在词尾 后加-er 构成比较级 或-est构成最高级. 如： 原级 比较级 最高级 cld –—— clder –—— cldest bright——— brighter———brightest yung—— yunger—— yungest
2) 以字母 e 结尾的词只加 –r 或-st 构成 比较级和最高级。 原级 比较级 最高级 nice ——— nicer –——— nicest fine——— finer———— finest large —— larger ———— largest
3) 重读闭音节词末尾只有一个辅音字母时, 先双写这个辅音字母, 再加-er或-est。如: big – bigger – biggest thin – thinner – thinnest 4) 以“辅音字母+ y”结尾的双音节词， 先改y为i, 再加-er或-est。如： easy – easier – easiest happy – happier – happiest
5) 多音节词和部分双音节词在词前加mre 或mst。如： delicius – mre delicius – mst delicius interesting – mre interesting – mst interesting imprtant—mre imprtant —mst imprtant
carefully---mre carefully--mst carefullyquickly---mre quickly ---mst quicklyslwly---mre slwly ---mst slwlyeasily--- mre easily ---mst easily
B: heavy easy tidy dry busy happy healthy hungry early
y -- i-- est
C: large late nice
thin “双写”
delicius dangerus interesting ppular beautiful careful friendly
the mst -- adj .
better best
wrse wrst
mre mst
farther farthest
less least
1. gd 2. cmfrtable 3. big 4. happy 5. cheap 6. many 7. difficult 8. little
better best mre cmfrtable mst cmfrtable bigger biggest happier happiest cheaper cheapest mre mst mre difficult mst difficult less least
用法：英语中三者或三者以上相比较，表示“最……” 这样的最高程度概念时，要用 “the+最高级” 的结构表示。这种句式一般带有表示比较的介词短语，比如: in ur class, f the three 等。例如：Wang Lin is the tallest in ur class. This theater is the cheapest f the three.注意使用最高级时应注意以下几点：
(1) 表示 “最……之一” 的句式，要用 ne f the +形容词最高级+复数名词。例如: Jingjiang Htel is ne f the biggest htels in ur city. Lisa is nt ne f my best friends. (2) 当最高级前面有物主代词或名词所有格时， 不加定冠词 the。例如：Tm is Lucy’s best friend. Tuesday is her busiest day.
(3) 最高级前可加序数词。例如：The Yellw River is the secnd lngest river in China.(4) 形容最高级修饰作表语或介词宾语的名词，代词时，被修饰的词往往省略。例如：He is the laziest (student) in ur class.
2. 形容词比较级和最高级的构成 规则变化一般情况下，单音节或双音节的形容词比较级直接加-er, 最高级直接加-est。如： clever—cleverer—cleverest cheap—cheaper—cheapest few—fewer—fewest small—smaller—smallest yung—yunger—yungest
b. 以-e 结尾的形容词，比较级+ -r,最高级+ -st。如： large—larger—largest nice—nicer—nicest cute—cuter—cutestc. 以辅音字母+y结尾的形容词，变y为i +er或+est。 busy—busier—busiest heavy—heavier—heaviest easy—easier—easiest happy—happier—happiest dirty—dirtier—dirtiest
d. 以重读闭音节结尾，末尾只有一个辅音字母结 尾的词，双写最后一个辅音字母，再加+er或 +est。 如： big—bigger—biggest thin—thinner—thinnest fat—fatter—fattest ht—htter—htteste. 多音节和部分双音节形容词，需在原级前+mre 构成比较级，+ mst 构成最高级。如： imprtant—mre imprtant—mst imprtant beautiful—mre beautiful– mst beautiful difficult—mre difficult—mst difficult
最高级，很容易，一般词尾加est。(cheap-the cheapest)词尾若有哑音e, 直接就加st。(clse-the clsest)重读闭音节, 单辅音字母要双写。(big-the biggest)辅音字母加y, 记得把y变为i。(friendly-the friendliest) 多音节，考考你，the mst到底加哪里？(ppular-the mst ppular)
1.We are ging t the Green Restaurant fr lunch. (就划线部分提问) ____________ yu ging fr lunch? 2. Sam is the shrtest in his class. (改为同义句)Sam is ________ than ____ _____ student in his class.Sam is _______ than _____ _____ students in his class.Sam is _______ than________ ______ in his class.3. Hw d yu like Screen City?
