andThink观察所圈单词，哪些是可数名词？哪些是不可数名词？它们有什么特点？观察1观察句子种类，你能找到选择疑问句吗？观察2名词的数可数名词countablenoun不可数名词uncountablenoun单数复数名词的数不可数名词有单复数吗？既作可数名词又可作不可数的名词你知道哪些？一、可数名词和不可数名词可数名词：可以计数的名词称为可数名词。一般有单数与复数两种形式，前面可加a，an或数词来修饰。不可数名词：不可计数的名词称为不可数名词。没有复数形式，前面不能用不定冠词a，an，

也不能直接加数词，但可以跟某些量词短语搭配，表示数量。

如：aglassofwater,twocupsoftea.CountablenounsUncountablenounspotatoestomatoesonionsstrawberriesappleseggsorangesbeefmuttonchickenriceporridgeorangejuicegreentea1.可数名词：可数名词有单数、复数之分。

其复数形式一般要加-s或-es。e.g.potato—____________;

tomato—____________2. 不可数名词没有复数形式，只有单数形式。e.g.some

_________(米饭)；

alotof

________(牛肉)ricebeefpotatoestomatoes不可数名词表示数量的多少时，必须

与表示数量的名词连用，即“数词+表示

数量的名词（可数名词）+of+不可数名词”。e.g.

两玻璃杯果汁

_____________ofjuice

三碗米饭

_____________ofrice

three

bowls

two

glasses(2)不可数名词作主语时，谓语动词只能用单数形式。e.g.

There_________muttonsoupinthebowl.

【拓展】如果不可数名词前有复数名词短语修饰时，谓语动词须用复数形式。

房间里有两袋大米。__________twobagsofriceintheroom.issomeThereare特别提醒有些名词既可作可数名词，也可作不可数名词，但两者的含义不同。如:GrammarFocus单词可数名词词义不可数名词词义chicken鸡鸡肉room房间空间fish鱼鱼肉orange橙子橙红色glass玻璃杯玻璃GrammarFocus3aReadthesentences.Circleallthenounsforfoodanddrink.Aretheycountableoruncountableinthecontext?Whatdoyouusuallyhaveforbreakfast?Iusuallyhavesomebreadandmilk.SometimesIhaveeggsandbeans.Whichwouldyoulikewithyourmeal,riceornoodles?Noodles,please!Wouldyoulikejuiceorcoffee?No,thanks.I’dlikeacupoftea.二、选择疑问句（alternativeQuestions）选择疑问句提供两种或两种以上情况，问对方选择哪一种，选择项用or连接定义i选择疑问句不能用Yes或No来回答，一般在所提供的备选范围内选择，有时也可以根据情况用不定代词either,both,neither,all,none作简略回答。1.A:Isshetallorshort?
