强调: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 读音:[z] 如:mango-mangoes tomato-tomatoes hero-heroes 2) 无生命的+s 读音:[z] 如:photo-photos radio-radios 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:a glass of water, a piece of paper, a bottle of juice 判断步骤: ↗如是am、is或was→原形 读句子→读该单词→认识该单词→理解意思→看be动词 ↘如是are或were→加s或es 练一练: 1、写出下列各词的复数。 I _________ him _________ this _______ her ______ watch _______ mango_______child _______ photo ________ diary ______ day________ foot________ dress ________ tooth_______ sheep ______ box_______ strawberry _____ thief _______ engineer______ peach______ sandwich ______ man______ woman_______ leaf_______ people________ 2、用所给名词的正确形式填空。 (1)Are there two ( box ) on the ? (2)I can see some ( people ) in the cinema. (3)How many ( day ) are there in a week? (4)Here’re five ( bottle ) of ( juice ) for you. (5)This ( violin ) is hers. Those ( grape ) are over there.
