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.
