　　Ⅵ. 短文改错

　　Today I'd like to tell you anything about riding a bike in Wuhan. If you visit Wuhan, you'll see many buses, cars and bikes. It's very cheap to use bike. If you take a bus, you often have to wait for half an hour or so. What's more, the buses move very slow and are quite crowded. I was used to go to the stadium by bus. I often arrived there late, feeling tiring. Then a friend suggested I went to the training classes by bike. I accepted his advice. Take a bus takes 30 minutes, while riding a bike takes 15 minutes. It is not out of date at all. Instead, I love riding to attend the classes but in this way I feel more better.
