动词-ed形式作定语
动词-ed形式作表语
动词-ed形式作宾语补足语 过去分词作定语往往与被修饰的词靠得很紧, 渐渐地成为一个复合词。这种分词叫分词形容词 (the Participle Adjective), 实际上相当于一个单纯的形容词, 除表示“完成”的动作之外, 还表示“被动”的意义。如:
spoken English (英语口语);
iced beer (冰冻啤酒);cooked food (熟食);
fried chips (炸土豆条);一、动词-ed形式作定语 但要注意不及物动词的过去分词常表示“完成”的动作, 而不表示“被动”意义。如: boiled water(开水); fallen leaves(落叶) the risen sun(升起的太阳)等。 1. The tall man is a returned student.
高个子的那个人是个归国留学生。

激动的人们冲进大楼。
(=the people who were excited)
Lost time can never be found again.
虚度的时光, 无法挽回。
(=time which is lost) (2)后置定语
①少数单个动词的-ed形式, 如left等, 只能
作后置定语。
1. Everything used should be marked.
所有用过的东西应该做好标记。
2. Among the invited were some ladies.
被邀请的人中, 有些是女士。
3. The books left are for my students.
剩下的书是给我的学生的。 ② 动词-ed形式短语作定语时,通常要放在被修饰的名词的后面,在意思上相当于一个定语从句。
1. Is there anything planned for tonight? 今晚有什么活动吗?
(=That has been planned for tonight)
2. The meeting, attended by a lot of
people, was a success.
这次会议有很多人出席, 开得很成功。

而是表示主语的状态或思想感情等。如:

看完信后, 他显得很忧虑。
When we heard of it, we were deeply moved.
当我们听到这件事时, 被深深地感动了。

 she came back.

He believed that one should always be curious and his most famous saying was: ”Leave the beaten track occasionally and dive into the woods. Every time you do you will be certain to find something that you have never seen before. Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the result of thought.”他认为一个人应当具有好奇心,他最著名的一句话是:“偶尔离开平路去寻求困境。当你这么做的时候,你一定会发现你从未见过的东西。跟踪下去,不断探索,不知不觉中,你就会发现某种值得思考的东西占据着你的头脑。所有真正伟大的发现都是思考的结果。”beaten track 踏平的路;一贯的路;惯例。如:

The situation is improving, but we are not out of the woods yet. 情况正在改善,但我们还没有摆脱困境。 2. Although he is most often associated with the invention of the telephone, he was indeed a continuing searcher after practical solutions to improve the quality of everybody’s life.

Zhang Jie, for advice.
MB: Hallo, is that Zhang Jie? This is Mary. I’m thinking of buying a new mobile phone. What do you suggest?ZJ: Hallo Mary. I’m happy to help. It’s lucky you could get through. I’ve been having some trouble with the line and I keep getting cut off. If the line goes dead, ring me back immediately on my mobile and it should be OK. Now what do you want your mobile to do?MB: Well, I’ve heard about mobiles that are computers and can take photographs as well. Do you think they’re a good idea?
ZJ: Mmm. Yes, they’re useful. I can use the Internet even when I’m on the train.MB: So you suggest one like that then?

Thank you, Zhang Jie, I think I’ll wait for that one. Goodbye.
ZJ: Goodbye.2. speaking & writing Look at these Chinese inventions on P68 in pairs and discuss what you know about them. Think about what they were used for and the date they were invented. Collect the information by doing some research. Fill in the chart and prepare to talk about one of the inventions to the class. 1 An abacus is used to calculate mathematical problems including equations. It is more efficient than using the brain alone.It was never used in the West, but it is closest in fun_ction to a modern personal calculator.2 The printing press was used to print messages from the Emperor to the people. It helped the efficiency of government.Gutenburg(1398-1468)began to print books on his press about 1450AD in Germany.3 A water-powered clock was used to measure the position and movement of the stars in the sky. It dates back to the Northern Song Dynasty.The West did not even discover the sun was the centre of the universe until Copernicus in the fifteenth century AD. You have been asked to write an entry for an encyclopedia about one of these three Chinese inventions. Choose one and prepare to write your report. You will include a photograph or drawing, but you must explain some important points in your report: Writinga description of the object
what it was used for
how it was used
when it was invented Make sure that each point is a new paragraph. Make the first sentence of each paragraph a topic sentence and then add all the information. Finish the report by station when it was produced in China and when it was found in Western countries. A sample version:
The abacus is typically constructed of various types of hardwoods and comes in various sizes. The frame of the abacus has a series of vertical rods on which a number of wooden beads are allowed to slide freely. A horizontal beam separates the frameinto two sections, known as the upper deck and the lower deck.
The standard abacus can be used to perform addition, subtraction, division and multiplication. The abacus can also be used to extract square-roots and cubic roots. The abacus is prepared for use by placing it flat on table or one’s lap and pushing all the beads on both the upper and lower decks away from the beam. The heads are manipulated with either the index finger or the thumb of one hand. Each head in theupper deck has a value of 5; each beads in the lower deck has a value of 1. Beads are considered counted, when moved towards the beam that separates the two decks. After 5 heads are counted in the lower deck, the result is carried to the upper deck; after both heads in the upper deck are counted, the result 10 isthen carried to the left-most adjacent column and so on. Floating point calculations are performed by designating a space between 2 columns as the decimal-point and all the rows to the right of that space represent fractional portions while all the rows to the left represent whole number digits. The abacus is one of many counting devices invented to help count large numbers. The earliest counting device was the human hand and its fingers. Then, as larger quantities (larger than ten human fingers could represent) were counted, various natural items like pebbles and twigs were used to help count. Merchants who traded goods not only needed a way to count goods they bought and sold, but also to calculate the cost of those goods. Until numbers were invented, counting devices were used to make everyday calculations. 课件68张PPT。ReadingLead-in Telephones become part of our life. But do you know who invented the telephone?

Listening and speaking Zhou Rui has decided to do a project on a living British inventor called James Dyson. So he telephoned Dyson’s company in England to interview one of its engineers about the great man’s ideas. Situation 1. Listen to the tape and tick the words you hear.□ washing machine □ drum
□ refrigerator □ court
□ carpet cleaner □ bicycle√√√√Washing machines at that time do not clean the clothes as well as by hand.He invented a machine using two half drums which move in opposite directions. 2. Listen again and make notes on James Dyson’s invention.Listening textGOOD DESIGN IS PRACTICAL
Zhou Rui is making a telephone call to an engineer who works for Janes Dyson, a famous British inventor. DS: Hello. Can I speak to Zhou Rui, please? This is Dr Smith.
ZR: Gook morning, Dr Smith. How kind of you to ring me back? Do you think you can accept my phone interview now? I’m very interested in James Dyson’s inventions and ideas. DS: Sure. I’m happy to speak about our company and its founder, James Dyson. He is not an inventor who makes something entirely new. He takes everyday products, like washing machines, and makes them work better. ZR: I see. How did he improve the washing machine?
DS: He found that clothes were not as clean from a washing machine as those washed by hand.
ZR: Really? Is that true? DS: Yes, because most machines had one large drum and the clothes went round and round in it.
ZR: So what can you do to improve that?
DS: This is the clever part. James Dyson invented a system with two drums in the same machine. Together they are the same size as the old drum but work differently. One drum goes in one direction and the other goes in the other. So it’s more like hand-washing and the clothes come out cleaner.
ZR: Was it easy to design? DS: No. It took many working models before Mr Dyson was content with the result.
ZR: How long did it take him?
DS: I’m not sure. But I know that when he invented a new carpet cleaner it took five years to design and over 5,000 tests before he was satisfied. ZR: Wow! I didn’t realize it took so long.
DS: Oh, there are more problems even after you get the patent. For example, during the early years James Dyson found that a large company making carpet cleaners in America was copying his ideas. He had to go to the court to protect his invention.
ZR: I hope he won.
DS: Yes, in the end that company had to pay us a lot of money because they had used our ideas illegally. It was an important day for us. ZR: What new ideas does James Dyson have?
DS: I’m sorry but you’ll just have to wait and see!
ZR: Thank you and I’m afraid I shall have to ring off now. Goodbye.
DS: Goodbye. 3. You want to apply for a job in James Dyson’s company. So you ring up one of his engineers to ask what kind of person he needs. Remember to ask for as much information as you can. Here some phrases that may be useful for you to make a telephone call:DialogueHold the line, please.
Hang on, please.
Just a moment, please.
I’m sorry, but this phone is out of order.
I can’t get through.
Sorry. He / She isn’t here right now.
Can I ring back later?
I’ll ring him / her up again.
I must ring off now because… S: Hello, is that James Dyson's company?
E: Yes, Who's that?
S: This is Li Ping. Is that the personnel manager?Sample dialogue: (S-student; E-engineer) E: Just a moment, please. Sorry. He isn't here right now. Can I take a message?
S: No, thanks. Maybe I'll ring him
again some other time. By the
way, may I ask you some
questions?
E: Sure, go ahead.S: I want to apply for a job in your company and I want to ask what kind of person you need.
E: Well, as far as I know, we need some skilled workers who are good at machinery and have a good knowledge of repairing some electrical equipment used at home, for example washing machine, refrigerator, electric fan and so on.
S: Are we graduates needed in some departments in your company ?
E: It's hard to say now. Maybe you will have some chance to work and learn in some department, but you have
to wait and see. lf you are free, you may call the personnel manager at three o'clock this afternoon.
S: OK, I will. By the way, how much will I get if I can work as your colleague?
E: Usually the average salary for new-comers is $2,000 per month. And you may get a rise if you progress well or have some invention in your work.
S: Well, I know. l must ring off now because I have to go back home for lunch. Thanks a lot. Bye!
E: Goodbye and good luck! Writing Now write a letter to James Dyson asking him for a job in his company. Here is the beginning and ending:Dear Mr Dyson,
