How about _( her, hers, she)?(四)句子成分:英语句子成分分为七种:主语、谓语、宾语、定语、状语、表语、宾语补足语。
19、1、主语是句子所要说的人或事物,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
20、接宾语。间接宾语一般放在直接宾语的前面。如:He wrote me a letter .有时可把介词to或for加在间接宾语前构成短语,放在直接宾语后面,来强调间接宾语。如:He wrote a letter to me .5、定语修饰名词或代词,通常由形容词、代词、数词等担任。如: Shanghai is a big city .6、状语用来修饰动词、形容词、副词,通常由副词担任。如:He works hard. (他工作努力。)7、宾语补足语用来说明宾语怎么样或干什么,通常由形容词或动词充当如:They usually keep their classroom cleanHe often
21、helps me do my 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)
22、该句式中只有一个主语,主语为单数时,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“
23、有”的含义。区别如下:there 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 te

25、词13 - 19是个位数词的词干后加-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 ar
