六. There be结构
1. There be句型主要用以表达“某处有某人(某物),强调存在”其基本结构为“There be+某物(某人)+某地”,有时为了强调地点,也可把地点状语放在句首。
There is a book on the desk. On the desk there is a book.
(1)肯定句:“There be+主语(某人/某物)+介词短语”
There are three people in my family. 我家有三口人。
There is a pen and two books on the desk. 书桌上有一支钢笔和两本书。
(2)否定式:“There be +not+主语+介词短语”
There isn’t a boy in the room.房间里没有一个男孩。 There aren’t any books on the desk.书桌上没有书。
注意:“There be句型”的否定式的构成和含有be动词的其他句型一样,在be后加not或no即可。
注意not和no的不同:not是副词,no为形容词,所以not a/an/any+n,相当于no+n。
There aren’t any pictures on the wall. =There are no pictures on the wall.
There isn’t a bike behind the tree. =There is no bike behind the tree.
(3)疑问式:Be there+主语+介词短语?”
肯定回答是:“Yes, there be.”否定回答是:“No, there+be与not的缩写形式”。
—Is there a lamp in your bedroom?在你的卧室里有台灯吗? —Yes, there is.是的,有。
—Are there any clock in the living room?客厅里有钟吗?
—No, there aren’t.不,没有。
(4)特殊疑问句:一般有两种句型结构
How many+复数名词+are/were there+介词短语?
There’re many children in the park. How many children are there in the park?
How much+不可数名词+is/was there+介词短语?
There was little rain around the year. How much rain was there around the year?
2. have表示“某人拥有某人或某物,强调拥有和所属关系”。
The man has two cars.
3. There be句型中的就近原则,即be和距其最近的主语保持一致。
There are some pens and a book on the floor. =There is a book and some pears on the floor.
七. 选择疑问句
选择疑问句是指说话人提出两种或以上的情况,让对方选择是哪一种,两个选择部分用or连接。选择疑问句不用yes或no来回答,直接在两个选择里选一个回答。
---Is she tall or short? ---She is tall.
---Can you play the piano or play the guitar? ---I can play the piano 八. 名词
1. 名词单数变复数规则
在英语里面,名词分可数名词(countable noun)和不可数名词(uncountable noun)。不可数名词没有单复数之分,用时只当单数词用;可数名词有单复数之分,一个的前面要用a或an,eg: a pencil, a basketball, a dictionary, an egg, an ID card,而复数即两个或两个以上的要作相应的变化,情况如下:
(1)一般的词在单数词后直接+“s”
book→books,pen→pens,car→cars,map→maps,cartoon→cartoons
(2)以s,x,sh,ch结尾的词+“es”
box→boxes,watch→watches
(3)以辅音字母+y结尾的名词去掉“y”,改成“i”,再加“es”
family→families,comedy→comedies
(4)以f或fe结尾的词,先去掉f或fe,改成“v”再加es
knife→knives,wife→wives,handkerchief→handkerchieves
(5) 特殊词,特殊变化,需单独记:
child→children,man→men,foot→feet,woman→women tooth→teeth,sheep→sheep,deer→deer
2. 既是可数名词又是不可数名词的单词
chicken当“鸡肉”讲时是不可数,当“小鸡”讲时可数;
room当“空间”讲时不可数,当“房间”讲时可数;
fish当食物用“鱼、鱼肉”讲时不可数,当“鱼的种类”讲时可数;
hair泛指“毛发”时不可数,当“一根或几根毛发”讲时可数;
sound意思是“一般性的声音”时,不可数,指“一次发出的声音”时可数;
paper当“纸”讲时不可数,当“试卷”、“论文”、“证件”讲时可数;
time当“时间”讲时不可数,当“时代、倍数、次数”讲时可数;
exercise泛指“锻炼”时不可数,当“练习、做操”讲时可数
九. 一般过去时
一般过去时表示在过去某个时间所发生的动作或所处的状态(与现在无关) 。常与yesterday, last week, in 1989, just now, a moment ago, the other day等过去具体时间状语连用。
He was here just now. 他刚才还在这里。
What did you do yesterday? 你昨天做了什么事?
一般过去时基本结构
1. 肯定句形式:主语+动词过去式+其他
I was an English teacher one year ago. 一年前我是一名英语老师。
I bought a yellow dress yesterday afternoon.
昨天下午我买了一条黄裙子。
2. 否定句形式:①was/were+not; ②在行为动词前加didn't,同时还原行为动词

I didn't buy a yellow dress yesterday afternoon.
昨天下午我没买一条黄裙子。
3. 一般疑问句:①was/were提到句首; ②Did+主语+动词原形+其他?
Were you an English teacher one year ago? 一年前你是一名英语老师吗?
