Ⅲ.重点句型
1.Would you mind turning down the music?
2.whether和if引导从句的用法。
3.get的用法
【重难点分析】
1.Would you mind„?和Do you mind„? 用于询问或请求别人做某事,或请求他人的许可。
(1)mind后面可以用-ing形式,复合结构 one’s doing或if引导的从句。
例如:
Would you mind doing the dishes?= Do you mind doing the dishes?
= Please do the dishes.请把餐具洗了好吗?(表示请求别人做事)
Would you mind turning down the radio?
= Do you mind turning down the radio?请把收音机关小点好吗?
(2)Would you mind my doing„? = Do you mind if I do„?
这个句型用于询问他人意见或请求他人的许可。
例如:
Would you mind my smoking here?
= Do you mind if I smoke here?你介意我在这里吸烟吗?
Would you mind my asking you a question?
= Do you mind if I ask you a question?我问你一个问题好吗?
Would you mind my opening the window?
=Do you mind my opening the window?
= Can I open the window?我可以开窗吗?
注意:
在美国口语中还可以将这个句型用Would you mind me doing sth.?来表达,但是在书面表达中要用my。
Would you mind me using your car? 我用一下你的车好吗?
(3)询问有关人们感觉的一般性问题,可以用Do you mind„?通常不用Would you mind„? 如:
Do you mind people smoking in your house? 你介意别人在你家里吸烟吗?
这里不能说Would you mind people smoking in your house?
(4)这个句型的否定形式是在mind后加not,即Would you mind not„?或Do you mind not„? 如:
Would you mind not playing basketball here? 你不要在这打篮球好吗?
Would you mind not wearing those old jeans?
(5)回答Do/Would you mind„? 提出的问题时,表示允许要说No或Not at all等;
如果介意要做肯定回答Yes.或Yes,I’m sorry,but I do.等,如:
--Do you mind if I ask you a question? 我可以问你的一个问题吗?
--No,please do.可以,请问吧。
2.通常既可用whether 也可用if 表示“是否”来引导从句,常置于see,ask,learn,tell,wonder,doubt,find out等动词之后。
如:
I'm not sure whether /if I'll have time.我不敢肯定我是否会有时间。
He asked me whether/if I could help him.I want to know whether/if he lives there.只能使用whether的场合(1)只有whether能用在介词后面
如:
Success depends on whether we make enough effort.(2)在英语中与or(not)连用的词通常是whether
如:
Whether we help him or not,he will fail.不论我们帮助他与否,他都将失败。
(3)带to的动词不定式前用whether,而不用if
如:
Please tell us whether to go or stay here.请告诉我们是走还是留。
They didn’t know whether to agree or keep silent.他们不知道是应该同意还是保持沉默。
(4)whether可置于句首引导主语从句,而if不能
如:
Whether the meeting will be in Beijing is not known yet.会议是否在北京举行还不得而知。It's not sure whether he is free.他是否有时间不确定。
3.get on / get off(a / the bus,train,boat,plane)上/下(公共汽车、火车、船、飞机)如:
She got on / off the bus quickly.get on还可以表示为:相处融洽、继续。
如:
Get on with your work!继续工作吧!
I get on well with all my classmates.我和所有的同学相处都很融洽。
get的其它的用法:
(1)表示“到达,抵达”,如果后接表示到达某地的名词,get后面要接介词to,如果get后接的是地点副词就可以直接在get后使用。
如:
She got there at six.她六点钟到达那里。(there为地点副词)
When we got to the station,the bus was waiting.当我们到达车站时,汽车还在等着。(the station是名词)
(2)get sth.done使;受;让人做好;经历;让;做(该做的事)
如:
I'll just get these dishes washed and then I'll come.我得把盘子洗了,然后就来。
I must get the television fixed.我必须请人修理一下这台电视机。
(3)get与宾语+形容词连用,其意思是“使某物/某人成为”
如:
I got my feet wet.我把脚弄湿了。
It's time to get the kids ready for school.该给孩子们收拾好去上学了。
(4)成为
如:
My hands are getting cold.我的手冷。
The food's getting cold.菜凉了。
This skirt is getting dirty;it needs washing.这件短裙脏了,该洗一洗了。
He is getting old.他渐渐老了。
(5)获得,取得
如:
I must get some fruit in the market.我得在市场上买点水果。
I'll get something to eat before I got out.我出去之前要找点东西吃。

We spent a day in the country and picked a lot of flowers.Our car was full of flowers inside!On the way home we had to stop at traffic lights,and there my wife saw the bookshelf.It stood outside a furniture(家具)shop.“Buy it,”she said at once.“We’ll carry it home on the roof-rack(车顶架).I’ve always wanted one like that.”
What could I do? Ten minutes later I was twenty dollars poorer,and the bookshelf was tied on to the roof rack.It was tall and narrow,quite heavy too.As it was getting darker,I drove slowly.Other drivers seemed more polite than usual that evening.The police even stopped traffic to let us through.Carrying furniture was a good idea.After a time my wife said,“There’s a long line of cars behind.Why don’t they overtake(超车)?” Just at that time a police car did overtake.The two officers(警官)inside looked at us seriously when they went past.But then,with a kind smile they asked us to follow their car through the busy traffic.The police car stopped at our village church(教堂).One of the officers came to me.“Right,sir,”he said.“Do you need any more help now?”
I didn’t quite understand.“Thanks,officer,”I said.“You’ve been very kind.I live just down the road.”
He was looking at our things: first at the flowers,then at the bookshelf.“Well,well,” he said and laughed.“It’s a bookshelf you’ve got there!We thought it was——er,something else.” My wife began to laugh.Suddenly I understood why the police drove here.I smiled at the officer.“Yes,it’s a bookshelf,but thanks again.” I drove home as fast as I could.1.From the story we know that ________.A.the writer was poor and didn’t buy the bookshelf for his wife
B.the writer’s wife didn’t like the bookshelf at all
C.the writer was always glad to buy something for his wife
D.the writer was not very glad to buy the bookshelf for his wife
2.What made the writer think that carrying furniture was “a good idea”?
A.He could drive slowly and it was safe.B.Other drivers would let him go first.C.His wife could use a new bookshelf.D.He could save a lot of money and time.3.Why were the police and other drivers so kind to the writer?
A.Because they thought the writer liked studying very much and needed a bookshelf.B.Because they didn’t think it was polite to overtake a car with a bookshelf on it.C.Because they thought somebody in the writer’s family had died and he needed help.D.Because they thought it was dangerous to carry a bookshelf on a car.4.Why did the writer’s wife begin to laugh?
A.Because now she knew what mistake the police had made.B.Because at last her husband understood why the police had driven to the church.C.Because the officer was always looking at the flowers and the bookshelf.D.Because the police had helped them a lot.5.When did the officers begin to realize(意识到)they had made a mistake?
A.Before they arrived at the church.B.Before they overtook(overtake的过去式)the writer’s car.C.After one of them looked at the flowers and the bookshelf carefully at the church.D.After the writer’s family left the church.五.完成句子,每空一词
