Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in the space.
While many resources are spent on what seems a small return, the exploration of s
pace allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

A sign like this one means that there is a bike lane. If there is a bike lane, you are required to use it. If there is not a bike lane, you should ride with traffic as far to the right side of the road as possible.
When the signal light turns green, cars go. When you cross the street at a signal light, you should wait for the walk signal. Be sure to look carefully to the left, right and left again, before crossing the street.
When the signal light turns yellow, car drivers should slow down and prepare to stop. You should not cross if the light is yellow. The light is about to turn red, and cars will enter the intersection.
This signal is the WALK sign. It has a picture of a person walking instead of using the word WALK.
This signal is the DON'T WALK sign. It is part of the signal with the picture of a person walking.This is a picture of a red hand, meaning you should stop. You should wait to cross the street until the green picture of the person walking is showing.
Car drivers and bikers must come to a complete stop at STOP signs.
A yield sign means to slow down and be ready to stop.
If there are pedestrians(行人)or vehicles in or nearing the intersection,you must stop.
If there is no traffic in or nearing the intersection and it is safe,you may go through.

When people are working on the roads, parts of the road are often dug up or rough. Be careful when cycling. Rough roads could make you fall off your bike. If you must move into the road to go around a work area, you should stop and look carefully to be sure there is no traffic coming before going into the road.
A detour is a way of getting around a roadway that is closed. Roads are usually closed because of road work or dangerous conditions. If you must take a detour, be careful of roads you aren't used to.

Movie makers at one time worried that they might be put out of business by television. Recently, however, more and more people have been going to the movies. This may be partly because the economic situation in America has worsened. When at the movies, people forget their troubles, as they get involved in the story on the screen. Also, directors have recently been producing pictures that large numbers of people want to see.
Americans in the millions are returning to their love affair with the movies. Motion picture industry experts see two main factors responsible for this: an increased need by Americans to escape from economic worries and a large number of new movies with broad audience appeal.
Movie makers admit that their rising popularity is partly the result of poor economic conditions, which traditionally bring an increase in theater attendance. “When people are fearful about the future, they look for escape,” comments Jack Valenti, president of the Motion Picture Association of America. “In a shaded theater, with a 65-foot screen, you lose yourself for two and a half hours and people find this beneficial.”

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make a choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.
