20、cording to the outline given below inChinese:1.老年人与年轻人之间常会发生冲突；2.谈谈你对这种现象饿结识及解决办法。The Old and the YoungThe Old and the YoungOld people are always saying that young people are not what they were.Every newgeneration is different from the one that preceded it.Today the difference is very marked indeed.

21、On the one hand，the young are better educated.They have a lot more money to spend andenjoy more freedom.They grow up more quickly and are not so dependent on their parents.Theythink more for themselves and do not blindly accept the ideas of their elders.On the other hand，the old always assume that t

22、hey know more for the simple reason that they have been around a bitlonger.They don t like to feel that their values are being questioned or threatened.And this isprecisely what the young are doing.They are questioning the assumptions of their elders anddisturbing their complacency.What they reject

23、more than anything is conformity.Traditionally，the young turned to their elders for guidance.Today，the situation is reversed tosome extent.The oldif they are prepared to admit itcould learn a thing or two from theirchildren.Perhaps a mutually beneficial relationship between the two sides is more acc

26、ice per gallonbe 2 or 3 years from now?What will it cost then to fill up the gas tank of your vehicle?There is still a lot of fossil fuel in the world but the fuel that is easy to find and to extractfrom the ground is disappearing.Those searching for new supplies of fossil fuel must search inplaces

27、that are more difficult to work(due to the cold，the heat，the depth of the water，or theunfriendly political situation of the country).The cost of the search continues to increase，as doesthe expense of extracting the fuel.This expense is not only measured in dollars，but also in thedamages to the envir

28、onment.Now think of what it might cost you 2 or 3 years in the future for a tank of gas if youcontinue to drive the same types of vehicles.The automobile industry，in foreign countries and inthe United States，has developed the technology to help reduce these energy needs and to decreasepollution.This

29、 innovation is called hybrid cars.These cars are available in the US today from 2 or3 manufacturers and many more are on the way.What Are Hybrid CarsWhat Are Hybrid Cars?A vehicle is a hybrid if it has more than one source of power.We have hybrid vehicles allaround us such as diesel-electric trains，

30、diesel-electric buses，and nuclear-electric submarines.Maybe some of you remember the Mo-Ped，a modified bicycle that used a combination of agasoline engine and muscle power of its rider.In a similar manner，the gasoline-electric hybrid caris a combination of gasoline-powered car and an electric car.Wh

31、at Is Reason for Developing Such a Complicated CarWhat Is Reason for Developing Such a Complicated Car?There are two major reasons：1)To reduce tailpipe emissions and 2)To increase average gasmileage.These two goals interact with each other so that the overall performance of the hybrid carenhances bo

32、th of them，today s hybrids provide gas efficiency of 40 to 60 miles/gallon.Thehybrids have reduced emissions to approximately 10%of the Japanese standards or about equal tothe California standards，which are the most restrictive in the US.How Do Hybrid Car WorkHow Do Hybrid Car Work?There are two typ

33、es of hybrid cars.One is known as the parallel hybrid and the other isknown as a series hybrid.Both types use the same components，which are:Small Gasoline Engine Fuel Tank Electric Motor Generator(used mostly in the series hybrid)Batteries Transmission In the parallel hybrid，the fuel tank supplies g

34、asoline to engine and batteries supplypower to the electrical motor.Both the engine and the electric motor can turn thetransmission at the same time，and the transmission turns the wheels.An onboardcomputer controls the system so that the maximum efficiency is obtained.In a serieshybrid，the gasoline

35、engine turns a generator，which either charges the batteries orpowers an electric motor that drives the transmission.The gasoline engine never powersthe vehicle directly.How Do These Combinations Meet the Desired Goals?The key to hybrid car performance is that the gasoline engine can be much smaller

36、than theengine in a conventional high horsepower car.But how can this be when you will be competing onthe highway with much more powerful autos on the road?The answer is that a conventional engine must supply power for all driving conditions.Theengine needs to be powerful enough to accelerate onto a

37、 freeway and up hills，but it to use only asmall percentage of its power at highway speeds.In a hybrid，the gasoline engine provides the power at higher highway speeds and thebattery-electric motor combination provides the power for city driving and for acceleration needs.With this combination，each po

38、wer source works at its optimal level.Some other tricks the hybrid car uses to get more efficiency are as follows:The system returns energy to the battery when it decelerates.When you push on the brakes，the electric motor acts as a generator and recharges the battery.This energy is lost in aconventi

39、onal car.The hybrid can shut off the gasoline motor when it is not needed.This is very importantwhen you are doing stop and go driving in the city and you have to stop a lot(gasoline is notwasted by running the engine at idle while the car waits at a traffic light.)Hybrid cars are designed with the

40、latest aerodynamics.This reduces the drag at higherhighway speeds.Hybrid use low-rolling resistant tires.These are stiffer and inflated to a higher pressure andcause about half the drag of conventional tires.The ride is a little rougher but the gas saving canbe huge.Hybrid also use very lightweight

41、materials.This reduces the overall weight of the car and themileage is increased.The above designs will provide a very useful and comfortable auto that also gives you amaximum of gas mileage.Hybrids are somewhat scarce right now(about 3%of the cars sold in the US)but should beplentiful for next year

42、 s models().The above description of hybrid cars is meant to be only an introduction to this newtechnology.If you are interested in getting one of these marvelous cars in the future，you shouldstart your investigation now.Take a test drive in some of the available hybrid cars，you will findsome surpri

43、ses.One is that the cars are extremely quiet，they have additional insulation in order todecrease the need for air conditioning and heating(the purpose is to save energy but the resultingquietness is a very nice benefit).A second is that these cars are very peppy，unlike earlyautomobiles designed for

44、energy conservation.The advantages and disadvantages will vary witheach manufacturer，type and model of the hybrid.It will take a lot of time to look at all the variousmodels but it will be well worth it for your future driving pleasure.(N)There is enough fossil fuel in the world，but it will be diffi

45、cult to find and to extract itfrom the ground.(Y)In the US today，a lot of manufacturers are trying to produce hybrid cars in order toreduce these energy needs and to decrease pollution.(Y)Mo-Ped is one kind of hybrid vehicle.(NG)There are other types of hybrid which use different components.(N)In bo
