　　第一篇

Motoring Technology

　　1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.

　　Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don't miss important road signs or fall asleep.Most crashes result from human and not mechanical faults.

　　Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology"sees through"big vehicles blocking your view.

　　And improvements to seat belts,pedal（腳踏）controls and tyres are making driving smoother and safer.The colour of a car has been found to be linked with safety,as have,less surprisingly,size and shape.

　　But whatever is in the fuel tank,you don't want a thief in the driving seat and there have been many innovations（創(chuàng)新）.Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.

　　Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyons's personal chauffeur（司機）,but their latest efforts suggest that won't be soon.

　　31.To reduce car crash rate,many scientists are working hard to

　　A.design fully automatic cars.

　　B.develop faster electric vehicles.

　　C.analyze road deaths occurring worldwide each year.

　　D.improve the safety of cars and develop new fuels.

　　32.According to the second paragraph,most road accidents happen due to

　　A.heavy traffic.

　　B.human mistakes.

　　C.engine failure.

　　D.bad weather.

　　33.Which of the following safety developments is NOT mentioned in the passage?

　　A.Windscreens that can help drivers to improve their vision.

　　B.Radars that can help drivers to see obstacles in fog.

　　C.Devices that can help drivers to see through big vehicles.

　　D.Improvements in seat belts,pedal controls and tyres.

　　34.Satellite tracking and remote communication systems cna be used to

　　A.reduce oil consumption.

　　B.remove the obstacles on the road.

　　C.call for help when one's car crashes.

　　D.help drivers get out of a traffic jam.

　　35.Which of the following statements is true of robotic drivers?

　　A.It will take some time before robotic drivers are available.

　　B.Robotic drivers are not allowed to driveon busy roads.

　　C.Robotic drivers can never replace human drivers.

　　D.Robotic drivers are too expensive to use.

Good Table Manners

　　Manners play an important part in making a favorable impression at the dinner table.Here are some general rules:

　　Napkin（餐巾）use

　　The meal begins when the host unfolds his or her napkin.This is your signal to do the same,so place your napkin on your lap.Unfold it completely if it is a small napkin,or in half,lengthwise（縱向地）,if it is a large dinner napkin.

　　If you need to leave the table during the meal,place your napkin on your chair as a signal to your server that you will be returning.Once the meal is over,place your napkin neatly on the table to the right of your dinner plate.Do not refold it.

　　Use a napkin only for your mouth.Never use it for your nose,face or forehead.

　　Use of utensils（餐具）

　　Start with the knife,fork or spoon furthest from your plate,and work your way in,using one utensil for each course.

　　If soup is served,remember to spoon away from yoursefl.This helps stop the drips.Do not put the entire soup spoon in your mouth.Instead,fill a soup spoon about 75 per cent with soup,and sip（啜飲）it from the side noiselessly.

　　After finishing dinner,place the knife and fork parallel to one another across the plate with the knife alade facing inward toward the plate.

　　Using your fingers

　　Here's a list of finger foods:sandwiches,cookies,small fruits or berries with stems,French fries and potato chips,and hamburgers.

　　Chew（咀嚼）with your mouth closed and don't make noise;don't talk with your mouth full.

　　Bread must be broken with your hands.It is never cut with a knife.

　　Don't pick something out of your teeth.Instead,excuse yourself to the bathroom.

　　If possible,try not to cough at the table.

　　Do not put your elbows（肘）on the table.In France,it is essential to have both hands above the table at the same time.

　　Do not put bones or anything else on the table.Things that are not eaten should be put on your plate.

　　36.Where is the napkin normally placed during the meal?

　　A.On your chair.

　　B.On the table.

　　C.On your lap.

　　D.On your plate.

　　37.The napkin is used only for

　　A.your forehead.

　　B.your mouth.

　　C.your nose.

　　D.your face.

　　38.Which utensil is used first?

　　A.The knife.

　　B.The fork.

　　C.The spoon.

　　D.The one farthest from the plate.

　　39.All of the following are finger foods except

　　A.soup.

　　B.sandwiches.

　　C.cookies.

　　D.hamburgers.

　　40.Which of the following shows good table manners?

　　A.Talking with your mouth full.

　　B.Putting bones on your plate.

　　C.Putting your elbows on the table.

　　D.Chewing with your month open.

Renewable Energy Sources

　　Today petroleum（石油）provides around 40% of the world's energy needs,mostly fuelling automobiles.Coal is still used,mostly in power stations,to cover one-quarter of our energy needs,but it is the least efficient,unhealthiest and most environmentally damaging fossil fuel（礦物燃料）.Natural gas reserves could fill some of the gap from oil,but reserves of that will not last into the 22nd century either.Most experts predict we will exhaust easily accessible reserves within 50 years.Less-polluting renewable energy sources offer a more practical long-term energy solution."Renewable"refers to the fact that these resources are not used faster than they can be replaced.

　　Hydroelectric（水力發(fā)電的）power is now the most common form of renewable energy,supplying around 20% of world electricity.China's Three Gorges Dam is the largest ever.At five times the size of the US's Hoover Dam,its 26 turbines（渦輪機）will generate the equivalent energy of 18 coal-fired power stations.It will satisfy 3% of China's entire electricity demand.

　　In 2003,the first commercial power station to use tidal（潮汐的）currents in the open sea opened in Norway.It is designed like windmill（風(fēng)車）,but others take the form of turbines.

　　As prices fall,wind power has become the fastest growing type of electricity generation-quadrupling（翻兩番）worldwide between 1999 and 2005.Modern wind farms consist of turbines that generate electricity.Though it will be more expensive,there is more than enough wind to provide the world's entire energy needs.Wind farms come in onshore and offshore forms.They can often end up at spots of natural beauty,and are often unpopular with residents.And turbines are not totally harmless-they can interfere with radar,alter climate and kill sea birds.Scotland is building Europe's largest wind farm,which will power 200,000 homes.The UK's goal is to generate one-fifth of power from renewable sources,mainly wind,by 2020.But this may cause problems,because wind is unreliable.

　　41.According to the passage,which of the following is the most polluting energy resource?

　　A.Petroleum.

　　B.Coal.

　　C.Natural gas

　　D.Water.

　　42.China's Three Gorges Dam

　　A.is the first hydroelectric dam in the world.

　　B.is of the same size as the US's Hoover Dam.

　　C.can generate around 3% of world electricity.

　　D.is the largest hydroelectric dam in the world.

　　43.Which country took the lead in making use of tidal currents to produce power in 2003?

　　A.The UK.

　　B.China.

　　C.Norway.

　　D.The US.

　　44.One of the problems with wind farms is that

　　A.there is not enough wind.

　　B.wind is not reliable.

　　C.they can only be built on the sea.

　　D.they might influence the world economy.

　　45.According to the passage,resources like wind are

　　A.renewable.

　　B.recyclable.

　　C.damaging.

　　D.scarce.
