be 动词等的常用句型：1.Are you ……？你是……吗？2.You are not ……, are you ? 你不是……，是吗？3.How do you do？你好！（这个句型并不是真的在问问题。
而只是一个较正式的打招呼用语。
这通常是初次见面的寒暄语，回答的人亦可用同样句子How do you do？回答。
对”How are you ?的回答也是用“I’m fine ,thank you!为好。
而很少把自己的真实状况说出来，因此此句型只是打招呼而已。
在不太正式的场合，What’s up?和What’s new、也已经成为较常见的打招呼用语。
对于此类的问话，或打招呼用语的答复往往可以是“Great!”或“Good!”等。
4.What do you do？你是做什么工作的?5.How old are you? 你多大？6.I feel like doing? 我想要做……情景用法：这个句型的主语常用作第一人称，用来表示自己的真实想法。
可以翻译成“我想要做某事”的意思。
有时候可以用来询问别人的感受。
如：Do you feel like a game o tennis?(你想不想打网球？)否定形式为I don’t feel like doing…,doing 在句中是动名词的用法。
使用时要特别注意这个句型不要与I ‘d like to do …搞混，这两个句型虽然有些接近，但前者只能是接动名词的用法，而后者却只能接不定式.Eg. My mother told me she felt like eating a large meal tonight.Eg I feel like a bird sometimes.Eg, I don’t feel like doing anything right now.7.I feel…我觉得……情景用法：feel 在此多用作系动词，故后面常跟形容词做表语。
如经常出现的I feel good.和I feel very well.在这里good 和well 都是形容词，前者表示精神上舒适，心情好的意思；而后者表示身体上舒服。
五种基本句型-—主系表结构主（语)＋系（动词）＋表（语）主语，主语是五种基本句型都具备的。
从位置上来看，主语一般在句子开头，也就是一个句子的“头把交椅".从意义上理解,主语一般是一个句子的“陈述对象”，后面的一切都是针对主语来说的.主语一般是名词或代词（当然还有其他，这里暂且详细讨论)系动词是联系动词的简称,顾名思义，它是起到联系作用的动词,是连接主语和表语的。
系动词的数量是有限的，常见的只有十来个，我们把它们分成四组，这样有助于我们记忆系动词:一、be动词类: am、is 、are 、was 、were二、表示变化类：become、get 、turn 、grow 、go三、感官动词类: 眼（look ）耳(sound)鼻(smell）舌（taste)身(feel）四、表示延续性的动词：remain 、stay 、keep表语从位置上来讲,它总是在系动词后面（系动词和表语关系甚为紧密，没有系动词，就没有表语：没有表语,就没有系动词.二从意义上讲，表语通常是来说明主语的性质、特征的。
表语通常是由形容词、介词短语、名词、代词、动词不定式、doing 等来充当。
上面就是对主系表结构的简要介绍，其中,系动词是主系表结构的核心,它是这个结构的标志，看到了系动词,也就能立刻判断出句子的结构是主系表，因此，记住系动词非常重要。
练习找出下面句子中的主语、系动词及表语,并指出主语和表语分别是由什么词性或词类来充当的。
