7、 Ltd is a 1 joint venture that produces 2 eyeglasses in China. It produces 3 pairs of glasses each year. Almost all its glasses will be 4 over 100 yuan a pair, which is almost 5 as expensive as other similar quality glasses made in China. While 6 is under way, the major raw materials Shanghai Nojiri

8、 Optical Co., Ltd needs will be 7 . According to its original design, 60% of its products will be for 8 and the rest will be the home market. Shanghai Nojiris products are called“Mosta”, and this brand will be 9 by Shanghai Clock and Watch Corporation. The total 10 of the joint venture is 2.6 millio

9、n dollars, among which 40% is invested by Shanghai Glasses General Factory, 40% by the Japanese company, and 20% by the citys Jinjiang Group. SpeakingDialogue 1A: Welcome to our factory.B: Thank you. Im glad to have the opportunity to visit your factory. Ive heard a lot about it. Your factory seems

10、to have a good fame.A: Thank you. Our factory was built in 1998, but it gained a fame only a decade ago.B: Your factory looks quite big. How many workers do you employ?A: Roughly about 3000. Its a comparatively big factory.B: Do you have a big staff of engineers?A: Engineers account for about two-fi

11、fths of the total employees, that is, there are about 1200 engineers.B: No wander your products gain a large market both at home and abroad.A: Yes, these engineers work out new technology and design new products at quite a good place, and this enables our factory to develop fast and make much profit

12、.B: Im told that you mainly manufacture freezers and refrigerators.A: Youre right. 70% of our products are freezers and refrigerators, and the rest are microwave-ovens and air-conditioners. B: How many workshops do you have?A: There are 4. Ill take you to these workshops afterwards. B: Thank you.Dia

13、logue 2A: This is the freezer and refrigerator workshop. There are the models of our products.B: You produce four types of freezers and refrigerators, dont you?A: Yes. They are models X451, X851, X051 and X221. The demand for the latter two always exceeds that of the former.B: Thats also the case in

14、 our country. Owing to the fast pace of modern life, large volume refrigerators are preferred so that people can spend less time shopping. I heard that you dont produce compressors yourselves?A: Right. To ensure the quality of our products, we import compressors from abroad, especially from Italy.B:

15、 I know Italian compressors are of top quality. The coating of your products seems to be better than that of other refrigerators in China.A: Yes. That makes our products gain a good reputation at home. Our products wont get rusty in at least 10 years.B: I see. You must have gained a considerable pro

16、fit these years.A: Yes. But the prospect wont be so optimistic as it used to be owing to the increasingly keen competition and shrinking demand. Our sales have come down a bit this year.B: Dont worry. Things will improve so long as you try.Dialogue 3A: This is the air-conditioner workshop. It is a j

17、oint venture business with a Japanese corporation.

Workers must feel comfortable working here.A: Yes. It is designed to create satisfactor

18、y working conditions.B: It seems to me that you are working at full capacity.A: Yes, we have plenty of orders. Nowadays, with the increase of peoples income, the demand for air-conditioner is increasing year by year.B: But I know that your prices seem to be 5% higher than those of the similar produc

19、ts.A: Yes, our prices are a bit higher, but the quality is of first class. Now people care more about quality than prices.B: I see.A: Shall we go to another workshop?B: Lets go.Dialogue 4A: This is the microwave-oven workshop. It is the newest and smallest one in our factory. It was set up in 1998 w

20、ith two labs and a quality control section.B: How long have you been producing microwave-ovens?A: From 1998 we began to do experiments with magnetrons, and in April 1999, we successfully made our first microwave-ovens.B: How do you ensure that there is no microwave leak?A: Well, thats mainly done by

21、 the quality control section. Every microwave oven will be checked by sensitive detectors to see if there is any leak before it leaves the factory. So the quality of our products is guaranteed.B: What do you think of the prospect of microwave ovens in China?A: I think they have a large potential mar

22、ket. As a convenient and safe cooker, they are being widely and quickly accepted by Chinese families. I am confident in the next few years their demand will exceed its supply.B: This must bring you enormous profit.A: I hope so.B: Thank you for taking me around.A: Its my pleasure.New Words and Expres

40、sure of 3-5 MPa and a temperature of 500-800 at the end of the compression stroke. The fuel used has a self-ignition temperature of some 400 and therefore ignites when injected into the combustion chamber at an injection pressure of 10-25 MPa.In the petrol engine a homogeneous combustible mixture, s

41、upplied by the carburetor, is ignited by the sparking plug, but on the compression ignition engine the thorough mixing together of the fuel and air for complete combustion must be accomplished within the cylinder during some 35-40of crankshaft revolution. This presents difficulty and is accomplished

42、 by using a penetrating spray of finely-divided fuel and considerable turbulence of the compressed air in the cylinder. Even so, only some 80% of air supplied can be utilized, but the spark ignition engine can consume all the air induced.Compared with the spark ignition engine the high combustion pr

43、essures need a strong, heavy and costly construction, while the fine limits to which the fuel pump and injectors must be manufactured add to the expense. Even with extensive light alloy construction, the power to weight ratio is lower than for a petrol engine. Starting may present more difficulty du

44、e to the high compression pressure and the heat required for fuel ignition. Idling is less smooth, acceleration slower, maximum rev/min are lower and imperfect combustion will result in a lower bmep and obnoxious exhaust smoke.On the other hand, the higher compression ratio gives a greater thermal e

45、fficiency and thus an increased economy km/L. The fuel is cheaper and has a much reduced fire risk. Engine torque is greater at low engine speeds and in practice considerably less maintenance is required. Carbon, beyond a thin coating, does not form when the engine is operating correctly.New Words a

51、ngines that burn fuel inside the cylinder. Those that burn gasoline are known as gasoline engines. Other types of internal-combustion engines burn heavier oils or fuels. Of these types the diesel engine has come into the widest use. Each of this engine has a few main working parts; the auxiliary par
