數(shù)詞是用來表示事物的數(shù)目和順序的詞。

... ... ...
多位基數(shù)詞讀法
1）101~999的三位數(shù)由“百位數(shù)＋and+兩位數(shù)組成”。如：325—three hundred and twenty-five

635 six hundred and thirty-five

(二)冠詞 Articles
一.冠詞的定義
冠詞是一種虛詞，沒有詞義，沒有數(shù)和格的變化，不能單獨使用，只能幫助名詞或起名詞作用的其他詞類說明其意義。
冠詞分定冠詞和不定冠詞兩大類。定冠詞特指一特定名詞，不定冠詞泛指一般普通名詞。
二.不定冠詞的用法
不定冠詞有a和an兩種形式，a用在以輔音開頭的名詞前，an用在以元音開頭的名詞前。它的用法如下：
1.表示“一個”的意思，與數(shù)詞one相同。
例如：Rome was not built in a day.
羅馬不是一天建成的；偉業(yè)非一日之功
The project(項目，計劃) will be carried out（執(zhí)行，貫策） in a year or two.
2.表示一類人或事物。
例如：A dog is a faithful（忠誠的） animal.
Even a woman can do it.
3.表示“每一”，相當(dāng)于per，用于某些表示時
間、重量、長度等單位前。
例如：He earns two thousand yuan a month.
The train is running sixty miles(英里)an hour.
4.表示同樣的人或事物，相當(dāng)于the same。
例如：Birds of a feather（羽毛） flock (一群）together./They are people of a kind.
一群同樣羽毛的鳥在一起/物以類聚，人以群分。
