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（脚踏）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（创新）.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（司机）,but their latest efforts suggest that won't be soon.

A.design fully automatic cars.

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.

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（纵向地）,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（啜饮）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.
