Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies: the biological clock.
Barbara Wells exercised every morning. She woke up at 6:00 a.m. She ran about two miles before she went to work. But Barbara’s legs and back started to hurt. She did some exercise before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said, “Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercise after work.” Her legs and back didn’t hurt anymore.
Today, doctors are learning more about chronobiology(n.生物钟学), the study of biological(adj.生物的) clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep on time every night and to eat only when they’re hungry. Also, doctors discovered that some illnesses, such as heat attacks, occur(v.发生)most often in the morning. This information tells them that the best time to take heart medication may be at night. When patients take heart medication(n.药物)at night, they may prevent a heart attack in the morning.
Many doctors believe chronobiology(生物钟) can help us live healthier lives. It may be the right time to listen to these doctors!

In the UK, bus journeys are very common. Buses are often convenient（便利的）for the people who live or work in the city center. Passengers can avoid heavy traffic and not have to pay for the parking. However, taking the bus is just a necessary but boring part of life: they get on the bus, pay for it and sit or find a place to stand when it is crowded. Everyone seems sad and bored.
In Latin America, however, bus trips can be wonderful. For a start, films are showed on the buses between cities for passengers to have fun along the journeys. Local buses do not show films, but drivers usually turn on the radio and it can be great for passengers to listen to songs and get relaxed.
Even better than films and music are the sights and sounds on the buses. Local buses always go to parts of the town that passengers would not visit by themselves. There passengers can see shops that they have never heard about. And they can also see other cultures of the town from the windows of the buses.
Besides, passengers’ luggage（行李）is also interesting. It is common to see a happy dog’s head getting out of somebody’s bag or a lovely chicken“speaking cheerfully”under somebody’s arm. Once on a bus in Peru, a farmer even tied a sheep to the top of the bus. It was quite surprising.
In all, taking the bus in Latin America is really fun and unforgettable.
