表示確定數(shù)量時(shí) 用基數(shù)詞+ hundred，thousand，million，billion

三位數(shù)以上的數(shù)，從個(gè)位往前數(shù)，每三位數(shù)加一個(gè)逗號(hào)，從后往前數(shù)的第一個(gè)逗號(hào)代表thousand, 第二個(gè)逗號(hào)代表million, 第三個(gè)逗號(hào)是billion，注意這幾個(gè)詞不能用復(fù)數(shù)形式，后也不能加and。例如: 2,648 ?

two thousand, six hundred and forty-eight?

16,250,064?

sixteen million, two hundred and fifty thousand, sixty-four?

確切數(shù)目與不確切數(shù)目的表達(dá)：

hundred, thousand, million, billion等前面有

基數(shù)詞，表示確切數(shù)目時(shí)，用單數(shù)，后直接接復(fù)數(shù)名詞；如：

three ?hundred ?books ? ? ? ? ?

one hundred ?people

five thousand ?students ? ? ? ? ? ?

seven million ?starts

... ... ...

形容詞和副詞的比較級(jí) ?

大多數(shù)形容詞和副詞有三個(gè)等級(jí)：

原級(jí)、比較級(jí)、最高級(jí)。

一、形容詞比較級(jí)的構(gòu)成

1.構(gòu)成的不規(guī)則變化:

1. 構(gòu)成的不規(guī)則變化:

e.g. good / well – better – best ? ? ? ? ? ? ?

bad / badly – worse – worst

many / much – more – most ? ? ? ?

little – less – least

far – farther / further – farthest/ furthest

2.構(gòu)成的規(guī)則變化:

1) 單音節(jié)詞和少數(shù)雙音節(jié)詞一般在詞尾后加-er 構(gòu)成比較級(jí) 或-est構(gòu)成最高級(jí). ?如：

原級(jí) ? ? ? ? ?比較級(jí) ? ? ? ?最高級(jí)

cold –—— colder –—— coldest

bright——— brighter———brightest

young—— younger—— youngest

2) 以字母 e 結(jié)尾的詞只加 –r 或-st 構(gòu)成比較級(jí)和最高級(jí)。

原級(jí) ? ? ? ? ? ? ?比較級(jí) ? ? ? ? ? ? 最高級(jí)

nice ——— nicer ?–——— ?nicest

fine——— ? finer———— ?finest

large —— ? larger ———— largest

... ... ...

形容詞的最高級(jí)

1. 用法：英語中三者或三者以上相比較，表示

“最……” 這樣的最高程度概念時(shí)，要用 “the+最高級(jí)” 的結(jié)構(gòu)表示。這種句式一般帶有表示比較的介詞短語，比如: in our class, of the three 等。

例如：Wang Lin is the tallest in our class.

This theater is the cheapest of the three.

注意使用最高級(jí)時(shí)應(yīng)注意以下幾點(diǎn)：

(1) 表示 “最……之一” 的句式，要用 one of the+形容詞最高級(jí)+復(fù)數(shù)名詞。

例如: Jingjiang Hotel is one of the biggest hotels in our city.

Lisa is not one of my best friends.

(2) 當(dāng)最高級(jí)前面有物主代詞或名詞所有格時(shí)，不加定冠詞 the。

例如：Tom is Lucy’s best friend.

Tuesday is her busiest day.

... ... ...

最高級(jí)規(guī)則變化口訣：

最高級(jí)，很容易，一般詞尾加est。

(cheap-the cheapest)

詞尾若有啞音e, 直接就加st。

(close-the closest)

重讀閉音節(jié), 單輔音字母要雙寫。

(big-the biggest)

輔音字母加y, 記得把y變?yōu)閕。

(friendly-the friendliest)?

多音節(jié)，考考你，the most到底加哪里？

(popular-the most popular)

不規(guī)則變化

good / well – better - best

much / many – more - most

bad / badly / ill – worse – worst

little – less – least

far – farther/ further– farthest – furthest

old – older/ elder – oldest / eldest

... ... ...
