05 名词用法-2023【暑假分层作业】七年级英语（人教新目标版）

第05练名词的用法 1. 名词单数变复数规则 在英语里面，名词分可数名词（countable noun）和不可数名词（uncountable noun）。不可数名词没有单复数之分，用时只当单数词用；可数名词有单复数之分，一个的前面要用a或an，eg: a pencil, a basketball, a dictionary, an egg, an ID card，而复数即两个或两个以上的要作相应的变化，情况如下： (1)一般的词在单数词后直接+“s” book→books，pen→pens，car→cars，map→maps，cartoon→cartoon s (2)以s，x，sh，ch结尾的词+“es” box→boxes，watch→watches (3)以辅音字母+y结尾的名词去掉“y”，改成“i”，再加“es” family→families，comedy→comedies (4)以f或fe结尾的词，先去掉f或fe，改成“v”再加es knife→knives，wife→wives，handkerchief→handkerchieves (5) 特殊词，特殊变化，需单独记： child→children，man→men，foot→feet，woman→women tooth→teeth，sheep→sheep，deer→deer 2. 既是可数名词又是不可数名词的单词 chicken当“鸡肉”讲时是不可数，当“小鸡”讲时可数； room当“空间”讲时不可数，当“房间”讲时可数； fish当食物用“鱼、鱼肉”讲时不可数，当“鱼的种类”讲时可数； hair泛指“毛发”时不可数，当“一根或几根毛发”讲时可数； sound意思是“一般性的声音”时，不可数，指“一次发出的声音”时可数； paper当“纸”讲时不可数，当“试卷”、“论文”、“证件”讲时可数；time当“时间”讲时不可数，当“时代、倍数、次数”讲时可数；exercise泛指“锻炼”时不可数，当“练习、做操”讲时可数 1、 写出下列单复数 city zoo country tooth mouse boy broom car tree horse bus fox branch baby family dish radio photo piano knife leaf life thief man woman child foot boy watch diary day  book _____   dress sheep tea box     strawberry peach sandwich paper   Chinese Japanese German Australian Englishman Frenchman American Canadian 二、单项选择 1．His grandfather radio.
