編輯: 路逍遙 關(guān)鍵詞: 英語學(xué)習(xí)方法 來源: 逍遙右腦記憶

高考重點要求:

1.掌握基數(shù)詞、序數(shù)詞、分數(shù)詞、倍數(shù)、百分數(shù)、年月日、鐘點、年齡、序號的基本用法。

2.掌握不定數(shù)量詞、約數(shù)詞的表達方法。

數(shù)詞在各個題項中,單選、閱讀、聽力、寫作中發(fā)揮著很強的作用,往往用以說明事實的精確性和可信性。數(shù)詞是由兩大部分構(gòu)成的即基數(shù)詞和序數(shù)詞,而其他數(shù)字表示法如分數(shù),小數(shù)等均由這兩大部分的不同組合而構(gòu)成。
