A marathon is a long running race of 26.2 miles (42.195 kilometres). The first Olympic Marathon was held in Athens. Now, many cities host their own marathons every year. Some of the best- known marathons around the world are the New York City Marathon, the Boston Marathon and the Tokyo Marathon. Among them, the Boston Marathon which started in 1897, is the oldest yearly marathon in the world. As time goes by, the sport has become more than just a race.
Themes of marathons add fun and meaning to the hard miles. Runners run for helping sick kids, celebrating important events, or just enjoying nature. There is a famous marathon in Gisborne, New Zealand, which is known for being the first city in the world to welcome the sunlight every day. Runners can greet the sunrise as they race along the golden sandy beaches.
Marathon routes bring people more understanding of the old sport. Some routes provide great sporting challenges for runners. The routes offer various surfaces, from bridges to sand to hills. Runners of all skill levels can sweat freely and push their limits in the race. Some routes are well planned for runners to explore the many sides of a city. For example, the route of the Great Wall Marathon takes the runners along the great wonder of the world. The race can be an amazing chance to get to know Beijing, its people and local food.
A marathon is quite a journey for runners to enjoy the run, challenge themselves and experience the culture. There is so much more behind the race for us to explore.
Over the past few years, cars have become smarter and smarter. Some of them can even drive themselves. Now, our roads have followed the steps. In the United Kingdom alone, there are around650 kilometers of" smart roads" in use. Across the world, many more are being built. Some new technologies are being put to use.
▲ Roads that recharge(给……充电)
Global warming has forced us to search for new energy sources. Why not look to the roads? Piezoelectric roads, a new kind of smart road, use vibrations(震动) from passing cars to produce electricity. In fact, Piezoelectricity was invented in
1880. However, it has never been widely used before now. The U. K.'s Lancaster University is going to improve it.
▲ Built- in brain
Roads of the future may be able to know how many people are on them, send drivers updates(最新的情况) on weather and traffic jams, and recharge electric cars while driving.
This seems impossible, but one American company has almost made it come true. By sensing the weight of a car, the smart roads can track the speed of each wheel. The smart roads are like large touchpads(触摸屏) so that they can collect data(数据) by looking for wheels. And then the roads will send it to the drivers.
▲ Roads that never freeze
It can be dangerous to drive in snowy weather. A tech company in Israel has developed the Snowless roads. When they find snow or ice on their surfaces, the roads will heat themselves up, melting(使融化) them away. The company has succeeded in testing this project on a few Canadian roads and in some of its car parks.

Your opinion | Is it possible that" smart roads" would be widely used in China? Why or why not?{#blank#}5{#/blank#} |
A. At times, it may break down. B. Self﹣driving cars began to develop in 2010. C. It might be one of Baidu's self﹣driving cars. D. But self﹣driving cars have their own problems as well. E. And they are more environmentally friendly than regular cars. F. self﹣driving car can be seen everywhere in China. |
Don't be too surprised if you see a car going down the road without a driver in Beijing these days. {#blank#}1{#/blank#} Last month. Baidu began to test its self﹣driving cars on open roads in Beijing.
{#blank#}2{#/blank#} Since then, companies like Tesla. Uber and Baidu have been working to produce and test their own self﹣driving cars.
Self﹣driving cars are safer than regular cars. {#blank#}3{#/blank#} They can remove the stress of driving and allow disabled or blind people to get around more easily.
{#blank#}4{#/blank#} In one test. researchers pointed a laser pointer(激光棒) at the car's sensors(传感器) while it was moving. The car mistakenly thought that the laser beam was in its way and slowed down or changed the direction.
The software that is used to direct the cars may not be safe enough. {#blank#}5{#/blank#} When we use our computers or smart phones. they sometimes crash(崩溃) without any reason. But if this happened to a self﹣driving car. the results could be deadly. Improvements to the software could be a solution to this problem.
