问题     What do you use to get around town? A car? A bike? Your feet? Perhaps you should try a Segway!
    The Segway is perfect for short journey. It’ s an electric vehicle that consists of a platform between two wheels,with a pole that connects the platform to the handlebars. To ride it,you step up onto the platform,and control the Segway by moving your body. Lean forwards to go faster,and backwards to slow down.
    On older models, direction is controlled by a twist grip(扭转把手)on the left handlebar. This varies the speeds between the two motors, a decrease in the speed of the left wheel would turn the Segway to the left. With newer models you simply lean to the left or right. Meanwhile, a gyroscope(陀螺仪)detects your movements and prevents the machine from falling over. The Segway has a maximum speed of 19 km per hour and a range of about 38 km. After that,you need to plug it in and recharge the battery.
    Segways are used for a variety of purposes. People with mobility problems can now enjoy walks in the country with their friends and family. Some golfers use them as an alternative to the golf cart. And dog owners now have an easier way to take the dog to the park. A few police forces use Seg-ways,too. They allow officers to move quickly whilst maintaining contact with the public. They’ re also becoming a common sight on airport. However, the most popular use is in tourism, particularly for city tours. Visit any major tourist city in summer,sit outside a cafe for a while and there’ s a good chance you’ll see a group of tourists passing on Segways.
The last paragraph focuses on______.
选项 A、what a Segway is like
B、where to find a Segway
C、how to control a Segway
D、when a Segway is useful
答案D
