19、事物，回答是“谁”或者“什么”。通常用名词或代词担任。如：Im Miss Green.2、谓语动词说明主语的动作或状态，回答“做（什么）”。主要由动词担任。 如：Jack cleans the room every day.3、表语在系动词之后，说明主语的身份或特征，回答是“什么”或者“怎么样”。通常由名词、代词或形容词担任。如：My name is Ping Ping .4、宾语表示及物动词的对象或结果，回答做的是“什么”。通常由名词或代词担任。如：He can spell the word.有些及物动词带有两个宾语，一个指物，一个指人。指物的叫直接宾语，指人的叫间接宾语。间接宾语一般放在直

21、y lessons.（五）there be 句型“there be +名词词组”中，there为虚词，be后面的名词词组为句子的真正主语。该句式在使用时需注意如下几点：1、there be句式表示“有”时，它表示一种存在关系，通常带有一个地点状语，意为“什么地方（时候）有”。此外，其主语还可以带前置或后置定语。例如：There is a blackboard in the classroom. There are two old women waiting for you at the gate.2、在正式文体中，该句式中be动词的单复数形式取决于以下两种情况：（1）该句式中只有一个主语，主语

22、为单数时，be动词用单数；主语若为复数，be动词也用复数。（2）该句式中有几个并列主语，则按就近原则处理，即与靠近be动词的第一个主语保持一致。例如：1) There is a pen on the desk.2) There are three apples on the table.3) There is a dictionary and two pens on the desk.4) There are two pens and a dictionary on the desk.3. there be句型与have的区别：there be 句型和have都表示“有”的含义。区别如下：th

23、ere be表示“某处存在某物或某人”；have表示“某人拥有某物/某人”，它表示所有、拥有关系。e.g. He has two sons. 他有两个儿子。 There are two men in the office. 办公室里有两个男人。语法专项（三）（一）数词数词的定义：表示“多少”和“第几“的词,叫数词。其用法相当于名词或者形容词。数词分为基数词和序数词两种。基数词：表示数目的词是基数词，最基本的数词如下：1 one, 2 two, 3 three, 4 four, 5 five, 6 six, 7 seven, 8 eight, 9 nine, 10 ten,11 eleven,

24、12 twelve, 13 thirteen, 14 fourteen, 15 fifteen, 16 sixteen, 17 seventeen, 18 eighteen, 19 nineteen, 20 twenty, 30 thirty, 40 forty, 50 fifty, 60 sixty, 70 seventy, 80 eighty, 90 ninety,100 a hundred, 1,000 a thousand, 1,000,000 a million, 1,000,000,000 a billion.基数词 1-12 是独立单词，需逐个记忆。基数词13 - 19是个位数词

25、的词干后加-teen 构成。其中 thirteen, fifteen, eighteen, 变化不规则。基数词 2090 是在十位数词后面加 -ty 构成。基数词 2199 是在十位数词后面加上个位数词合成，中间加上连字符“-”。例如：21 twenty-one。基数词三位以上的数词，在百位和十位之间，一般要用连词“and”。例如：342 three hundred and forty-two表示“万”的词英语中没有，如1万可用10千来表示：ten thousand. 30万可用 three hundred thousand 来表示。【典型例题】例题1There are _ days in a

28、 bus Number Three busb 用基数词 词序为：名词（词首字母大写）+ 基数词（如用英语拼写，词首字母也要大写）如：Lesson One, Class Four, World War Two。此种方法较常见，特别是当数字较长时。如：Room 306, No.106 Middle School。注意：编号也可以用序数词 词序为：the + 序数词 +名词 如：the first lesson, the Second World War例题3Jim is in _ Middle School.A.
