名词表示某一事物,有具体的和抽象的之分。分为可数名词和不可数名词。
一定要注意:不可数名词都默认为单数,所以总是用is或者was;
最好不要根据some、any、a lot of等词去作判断,以免受误导。
1、可数名词如何变"复数形式":a.一般情况下,直接加-s,如:book-books,bag-bags,cat-cats,bed-beds;
读音:清辅音后读[s],浊辅音和元音后读[z]。b.以s、x、sh、ch结尾,加-es,如:bus-buses,box-boxes,brush-brushes,watch-watches;
读音:[iz]。c.以"辅音字母+y"结尾,变y为i,再加-es,如:family-families,strawberry-strawberries;
读音:[z]。d.以"f或fe"结尾,变f或fe为v,再加-es,如:knife-knives,thief-thieves;读音:[z]。e.以"o"结尾的词,分两种情况
1)有生命的+es如:mango-mangoes,tomato-tomatoes,hero-heroes;
读音:[z]
2)无生命的+s如:photo-photos,radio-radios;
读音:[z]
f。不规则名词复数:man-men,woman-women,policeman-policemen,policewoman- policewomen,snowman-snowmen,mouse-mice,child-children,foot-feet,tooth- teeth,fish-fish,people-people,Chinese-Chinese,Japanese-Japanese?2、不可数名词没有复数。如果要计算不可数名词所表达的数量,就得在数词和不可数名词之间加上"量词+of"。
例如:aglassofwater,apieceofpaper,abottleofjuice;
