be动词详解及精选练习题150道.doc
be动词是我们必须掌握的一个重要概念，虽然be动词少，但是由于其形式多变，给很多同学的英语学习造成了一定的困难，下面主要就be动词作一个专题复习。 1. be动词的概念：be动词是系动词的一种，是与一般动词（实义动词）相区别的概念。一般动词表示具体的动作。而be动词不是动作，它通常与名词、形容词或其它词类一起表示主语的性质、状态、身份、特点等等。一般动词很多，如：walk(走)、read(读)、stand(站立)等等，而be动词只有一个，那就是be，所以它称为be动词。be动词在不同的句子中有不同的中文意义，有时甚至不用翻译其意义。be动词有不同的形式，如：现在式有am, are, is三种，过去式有was和were两种，过去分词只有been一种形式。2. be动词的现在式用法：be动词的现在式有am, are, is三种，具体用哪一种，必须由主语的人称和数决定。如下表所示：be 动词用法歌： 动词用法歌： 我用 am,你用 are，is 连接他，她，它。 你用 ， 连接他， 单数名词用 is，复数名词全用 are。 ， 。 变疑问，往前提，句末问号莫丢弃。 变疑问，往前提，句末问号莫丢弃。 变否定，更容易， 莫忘记。 变否定，更容易，be 后 not 莫忘记。 疑问否定任你变，句首大写莫迟疑。 疑问否定任你变，句首大写莫迟疑。3. be动词的过去式用法：be动词的过去式是：was和were, 这两种形式与现在式用法没有多大区别，作谓语时用哪一种，还是由主语的人称和数决定。如(3)疑问句：be动词+主语如：(a) 一般疑问句及其回答：Are you a student? 回答：Yes, I am. No, I am not.注意：含be动词的一般疑问句回答用Yes或No. 其结构是：Yes, + 主语 + be动词 / No, + 主语 + be动词 + not.(b) 特殊疑问句：What is your name?How are you?Where is my pencil-box?4. There be句型：there be句型是含有be动词的一个重要句型。其结构如下：there + be动词 + 名词 + 地点状语There is a school there. 那里有一个学校。在这个句型中a school是真正的主语，be动词的形式由它决定。当这个名词是单数时，be动词是is或was, 当这个名词是复数时，be动词用are或were。如：There are many students in the classroom. 在教室里有许多学生There was an accident in the street last night. 昨晚这街上有个车祸。There were lots of people in the room when I got in. 当我进去的时候，屋里有很多人。there be句型的一般疑问句是将be动词提前，否定句也是将be动词后面加上not, 如：Is there any water in the bottle? 瓶子里有一些水吗？There arent any students in the room. 房间里没有任何学生。【练习题】一. 用括号中适当的词填空。1.
