四、阅读理解。
There are various ways to travel in a big city.
Taking the underground is a popular way. It is fast and can take you to different parts of the city quickly. However, it can be very crowded during rush hours. You may have to stand for a long time.
Riding a shared bike is also a good choice. It is convenient and you can stop anywhere you want. It's also good for your health. But sometimes, it's hard to find a shared bike when you need it.
Taking a taxi is the most convenient way. The driver can take you directly to the place you want to go. But it is expensive, and you may get stuck in traffic jams.
Now, more and more people choose to use ride hailing（叫车）apps like Didi. It's like taking a taxi but usually costs less. Maybe in the future, there will be even more convenient ways to travel in cities.
