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, the chance to save ourselves might not exist.

While many resources are spent on what seems a small return, the exploration of space 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.

I’ll never forget my first daughter, who died too early from a bad accident. During those years, life was   36  . One Christmas I found my 3-year-old daughter   37  with a roll of golden wrapping paper. I had bought the paper to finish a rather important project. So I became   38  and scolded her loudly, “You are not good. And you are   39  your father’s money. You don’t know how hard your parents are working.” She was   40  and cried bitterly, running away.
    41 , she brought a gift, a golden   42  made of golden wrapping paper to me the next morning and said, “This is for you, Daddy.” I was   43  of my earlier hurting words, but my anger rose again when I found out the box was   44 . I shouted at her, “Don’t you know, when you give someone a present, there is supposed to be something inside?” She   45  at me with tears in her eyes and cried, “Oh, Daddy, it’s not empty at all. I blew   46  into the box. They’re all for you, Daddy.”
I was completely   47 . I put my arms around her and begged for her   48 . A year later, a serious   49  took the life of my daughter. I was so sad that I   50  in bed for three days and three nights, saying nothing with tears rolling down my cheek. From then on, I hated cars and kept the golden box by my bed for many years. Whenever I was   51  , I would take out an imaginary kiss and   52  the love of my daughter who had put it there.
In a very real   53  , each one of us, as humans beings, has been given a golden container   54  with unconditional love and kisses ... from our children, family members, friends, and God. There are   55  no other possessions that anyone could hold more precious than this.

Home security products give a homeowner peace of mind as well as the ability to protect loved ones and physical possessions around-the-clock.

_____

Having the right security products equipped in a home can get rid of home invasion, theft and injury. Home security products should be hidden somewhat and not out in the open for invaders to see. Products that protect one's home should also be linked to the local police department so that they can be notified in the event of an emergency or break-in.

_____

Security products are used for monitoring the home and the properties surrounding the home. Products are designed to warn the homeowner when invasion is taking place or someone is hidden around the property. Most systems are electronic or battery powered and some are linked with cables and satellites to keep a close watch on property.

_____

 There are four main kinds of home security products. The first kind is home entry and invasion protection--used for setting up a high tech alarm system. The second is window and door alarms, helpful in warning the homeowner as to who is coming in and out of the house and certain rooms in the home. The third is to keep the outside of the home protected by signaling. The fourth is a combination of security gates, cameras connected to a DVR, bars for windows and doors as well as sliding door lock.

_____ 

 One should consider the expense of equipping a complete security system. For most complete systems which include driveway alarms, cameras, and electronic keypads, many can cost from $100 to $10,000. The homeowner can equip individual security products based on the needs of the home and family to save money.

_____

Preventing invasion, theft and injury can save thousands of dollars if the home was broken into and items were stolen. Having home security products equipped can also reduce car and auto insurance moneys.
