Biological Clock
When the sun rises on a warm and sunny day, you can see some flowers open up. When they close late in the afternoon, other flowers open.
Biological rhythms(生物节律), like the opening and closing of flowers, happen all over nature. But not all of them are daily rhythms. Some, like the beating of our heart, happen every second. (1)Scientists use the term biological clock to describe the timing that controls biological rhythms. (2) In some animals it is probably controlled by the brain. In plants and other living things that have no brain, it must be something else.
The migration of animals happens when a signal is sent out. For example, when days become shorter, birds leave the northern parts of the world and fly south where it is warm. (3)Humans also have biological clocks that control their daily rhythms. When people travel by plane from one continent to another, they often cross many time zones. Their internal clocks don’t seem to work correctly. We call this jet lag(时差). (4)People who work night shifts also have problems with their biological clocks. They may not be as active as people who work during the daytime.
Biological clocks control many rhythms of life. (5) Doctors are looking for new ways to make travelling more comfortable and medical treatment more effective.
A. But where can you find it?
B. This makes them feel tired.
C. In the summer they fly back to have babies.
D. We are learning more and more about them.
E. Biological clocks can be adjusted.
F. Other rhythms are based on months, seasons or years.

A travel agent can give you information on special economy fares for trains, buses and planes. Think about hiking or biking for a part of your trip, too. You’ll not only save money, but you’ll also see a lot more of the country.
Some students may want to travel by car. Be sure to think about going with other students—many colleges have “ride boards” that list when and where other students plan to travel. Many radio stations provide the same sort of service — they announce who’s driving where, when, how many riders they will take and what the expenses will be.
There are many inexpensive, older hotels near bus or train stations. Check your travel guide for names of the best. Many parts of the country also have youth hostels where young people can stay for only a few dollars a night.
You don’t have to eat in restaurants all the time, but we don’t recommend a diet of candy and cola, either. You can usually get a healthy, cheap breakfast in a restaurant. If the weather is warm, you can buy food in supermarkets or at roadside stands and have a picnic for lunch. For dinner you can get the names of good, cheap restaurants from travel guides or friends.

Today we live in a world where GPS systems, digital maps, and other navigation apps are available on our smart phones. 1 of us just walk straight into the woods without a phone. But phones 2 on batteries, and batteries can die faster than we realize. 3 you get lost without a phone or a compass, and you 4 can’t find north, a few tricks to help you navigate 5 to civilization, one of which is to follow the land... When you find yourself well 6 a trail, but not in a completely 7 area, you have to answer two questions: Which 8 is downhill, in this particular area? And where is the nearest water source? Humans overwhelmingly live in valleys, and on supplies of fresh water. 9 , if you head downhill, and follow any H2O you find, you should 10 see signs of people. If you’ve explored the area before, keep an eye out for familiar sights—you may be 11 how quickly identifying a distinctive rock or tree can restore your bearings. Another 12 : Climb high and look for signs of human habitation. 13 , even in dense forest, you should be able to 14 gaps in the tree line due to roads, train tracks, and other paths people carve 15 the woods. Head toward these 16 to find a way out. At night, scan the horizon for 17 light sources, such as fires and streetlights, then walk toward the glow of light pollution. 18 , assuming you’re lost in an area humans tend to frequent, look for the 19 we leave on the landscape.
