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 life. For example, people should know the safety measures to take before opening a hall door during a fire. Also, make sure everyone knows how to unlock doors that may be in the escape path. At times, a key is needed to unlock a door from the inside. So, keep the key in the lock, or, you can put the key on a key ring and put it where it can be found easily.

If you live in an apartment, know the ways you can use to get out. Show everyone in the family these routes. Stress the importance of using stairways or fire escapes, not elevators.

From most homes and the lower floors of apartment buildings, escape through windows is possible. Learn the best way of leaving by a window with the least chance of serious injury.

In a home fire, windows are often the only means of escape. The second floor window sill is usually not more than 13 feet from the ground. An average person, hanging by the fingertips, will have a drop of about six to the ground. Of course, it is after to jump a short way than to stay in a burning building. Rolling away from the building when you land.

Windows are also useful when you are waiting for help. Often you'll be able to stay in the room for several minutes if you keep the door closed and the windows open. Keep your head low in the window to be sure you get fresh air rather than smoke that may have leaked into the room.

On a second or third floor, the best windows for escape are those which open onto a roof or balcony. From the roof or balcony, a person can either drop to the ground or await rescuer. Dropping onto cement or pavement might end in injury. Bushes, soft earth, and grass can help to break a fall. A rope ladder should be considered when the drop is too great.

In a town where the fire department acts quickly, it may be best to wait for rescuer. Close the doors and wait by an open window for help. Shout for help. Be sure to close the door before opening a window. Otherwise, smoke and fire may be drawn into the room by the draft.

ver Germany in 1944, Royal Air Force Gunnery Sergeant Nicholas Alkemade jumped from 18, 000 feet without a parachute (降落伞), calculating that this would be a quicker and less painful death.Unbelievably, he suffered only slight injuries. The last part of his 122-mile-per-hour fall was broken by the branches of young pine trees, thick springy undergrowth, and finally deep snow. "It was rather like bouncing on a trampoline, " he recalled.Sergeant Alkemade's experience is a dramatic rebuttal of the idea that people falling from great heights are dead before they hit the ground. Asphyxia, brought about by the speed of the fall, and heart failure through shock were thought to occur long before the final impact.The fallacy of this belief has been amply (充分地) demonstrated by free-fall parachutists who regularly drop several miles before opening their parachutes. In 1960 Capt. Joseph Kittinger jumped from a balloon in the United States and fell 16 miles before opening his parachute. He landed conscious and unhurt.
