——數(shù)詞命題趨勢

數(shù)詞是歷年中考試題中的必考知識點之一，所占分值不多，一般在1～2分之間，題型有選擇題、詞形變換題等。從命題內(nèi)容來看，對基數(shù)詞和序數(shù)詞的基本用法、hundred,thousand,million,billion后面加不加-s或of、特殊形式的序數(shù)詞、分數(shù)表示法的考查是中考命題的熱點。預計年考查的重點極有可能是基數(shù)詞和序數(shù)詞的用法、分數(shù)表示法及hundred，thousand，million的用法。designedbyxiao2021/07/09定義數(shù)詞就是用于表示數(shù)目的多少或順序的先后的詞，分為基數(shù)詞和序數(shù)詞兩種。表示數(shù)量的數(shù)詞是基數(shù)詞，如one,two,three等；表示順序的數(shù)詞是序數(shù)詞，如first,second,third等designedbyxiao基數(shù)詞2021/07/091____________2____________3___________4___________5
