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-mangoestomato-tomatoeshero-heroes2)无生命的+s读音:(z)如:photo-photosradio-radiosf.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-Japanese2、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 table? (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.
