While the rest of the world carried on cycling during the 1950s and 1960s ,America forgot how; even high-school children would drive to school .Recently there has been something of a renaissance(复兴) in cycling, and in many areas it is a very useful way of getting around, especially where bike paths or bike routes have been built. You may well want to buy , hire or borrow a bike. 

     There are two important consequences (后果)of this earlier drop in cycling in the U.S.A. One is that many people do not to know how to cycle. That is, cyclists often behave more like Pedestrians(行人)than motorists: they ride on the sidewalk or on the wrong side of the road; they don't care for stop signs or traffic lights; they ride without lights at night; they give no hand signals .The other consequence is that cycling is regarded by many people not so much as a way of getting from one place to another but as a way of life, a form of exercise, etc. As a result, a large number of young Americans have ten-speed racing bikes. These are very high and fast and great if you are cycling long distances, riding up mountains or racing. At first , though, you may find them awkward (使用不便)for cycling in town. Sight-seeing or shopping ----they are expensive, uncomfortable and hard to control until you get used to them, and unsuitable for rough stony roads.

     There are also ordinary bikes around. If you get hold one of these ,you may find that brakes work by pedaling(踩踏板)backwards. This is perhaps safer than ordinary brakes when it is wet, but it seems to be less effective. This arrangement also means you can't pedal backwards in order to get the pedals in the right place for getting on or moving off.

68.   The passage gives us a brief introduction to _______________________.

     A. advantages of bikes                B. cycling in America

     C. American transportation            D. how to ride a bike

69.   Young Americans prefer racing bikes because they_________________.

     A. can help keep fit                    B. are easy to learn

     C. are safer to ride                     D. are expensive and popular

70.   Which of the following does NOT result from the early drop in cycling in the U.S.A?

     A. Cyclists do not care for traffic lights.

     B. People ride on the wrong side of the roads.

     C. Cycling is not considered a way of transportation.

     D. People have to pedal backwards to stop the bike.

Friedrich Dobl, a Yugoslav working in Germany, was fed up with traffic jams. At long weekends and holiday times when he wanted to get him quickly he always found himself behind hundreds of other cars moving slowly along the notorious foreign workers’ route through Germany and Austria.

How easy it all was for police and emergency services. A siren, a flashing light? And like magic everyone was out the way. Going home from work one night he passed a garage. And there in front of him was the answer to his problems. An old ambulance(救护车) was for sale. The red cross had been removed. But not the flashing light, and the siren. He tried the light. It flashed magnificently. He tried the siren. That too sounded impressive. He bought the ambulance and opened up for himself a dream world of motoring. It began early in the morning, all his luggage in the back of the ambulance and motorway in Germany looking reasonably clear. Soon, as always, a long line of traffic appeared ahead. He switched on the flashing light and set off the siren. Cars swiftly slowed and pulled off the fast lane. Other cars stopped and drivers waved him ahead to an open road all his own. In record time he crossed the border into Austria. The big bluff was working. Police even waved him through the confusion caused by an accident.

But then the Yugoslav made his big mistake. Until then he had only stopped for petrol. Now he was driving past a real accident, lights flashing , to late realize that it was not another traffic jam as he assumed. They stopped him, and after hearing the story of his ride across two countries fined him 12. 5 pounds.

1.At long weekends and holidays Friedrich Dobl used to ____.

2.Why did he decide to buy the ambulance?

3.The red cross had been removed ____.

4.Which of the following might be the best title for the passage?

We can all contribute to a greener world．Just follow these ten golden rules:
●Stop getting junk mail．Billions of junk mail can be sent every year．Half of it is never opened．Get-your name off mailing lists．If 100,000 people stopped getting junk mail today, it would save 150,000 trees a year．
●Stop reading newspapers．All over the world, millions of newspapers are thrown away every day, 44 million newspapers in the USA alone —that's half a million trees a week．Either recycle your newspapers or read the hews online．
●Buy clothes made from organic materials．Conventional cotton farming seriously pollutes the environment, most of which uses chemical pesticides （农药） and fertilizers． Organic is better!
●Switch to solar energy．In one day, the sun will provide enough energy to power the planet．Why aren't we using it?
●If you have to drive, share the ride．Most cars in the USA have only one occupant．Also, 25 percent of car rides are less than 1．5 kilometres．Get out and walk!
●Unplug your PC, TV and VCR．Simply turning them off isn't enough．Sets left on standby are still using 25 percent of their power．
●Hold on to your balloons．Helium-filled balloons which fly away usually end up in a lake or river, where they can choke aquatic (水生的) creatures．Save your balloons and use them again．Or better still, don't use them at all．
●Feed the birds．Wild birds need food, especially in v/inter when other sources can be scarce．The greater the range of foodstuffs you put out for them, the more types of birds you will attract．
●Plant a garden at your school．Learn the connection between the land and the table．Plant vegetables to eat, flowers to admire and trees to improve the air．

Have you ever thought of taking a train and having an adventure(奇遇)？Riding the train can be a real adventure. That is how I feel every time I take Amtrak. I often take a four－hour trip to visit my children. Every time I take this trip I never know what will happen.
Last week when I was on the train and over an hour into the train ride，there was a man sitting by himself in the back of the train carrying on a mobile phone conversation－in another language. It was loud and disturbed most of the people on the train. I think it was annoying.
Fortunately I sat next to a wonderful old lady who was taking a two－day trip by train. She said her two daughters were distraught at the thought of her driving for three days to reach her home，although she had no trouble driving. The train ride was the only choice for her. She loved to look out of the window and watch the world go by on the train.
She was fun to talk to and asked me when my children started being parents. That is a very good question. Both of us are old and have children. She asked that same question from time to time.
There are always many people on the train from all walks of life，different countries，and many  languages. Riding the train is a great way to increase your knowledge and take in all kinds of cultures. If you get hungry，you can buy food in the food car at any time. If you need to use the restroom there is always one available.
It sure beats driving the car，which has to stop for food and restrooms. And it is better than taking the bus.
