三、阅读理解 (共5小题，每小题5分)
What are you holding in your hand while you are taking the examination Right. A pen.
Though it is small, the pen has changed the history, improved the trade of countries, recorded events, carried news, and done far more work for human beings than all other tools.
Progress without it would have been almost impossible. The invention of the wheel, the introduction of the steam engine(蒸汽机), the use of electricity, all these have changed the lives of millions of people, but the pen has done more. It has taken away mountains, and it has prepared the way for all progress and development of the society.
In the past the pen did all the work if you wanted to keep any writing for some time. The lawyers took up their pens and wrote the law of the country from the days when papyrus(纸莎草纸) was first used. The most famous letters in the world were written with a pen. It was with a pen that the greatest thinkers of all time wrote down their thoughts.
The pen is very utilitarian. We cannot sign a bill or write a letter or buy a house without our pen. An agreement is worthless till our name is written with a pen. The writers encourage the world with it. The students take their examinations with it as well.
Our coming into the world is recorded with a pen. Before we have been at school, our name is written on the name list with a pen. We cannot be married till we have signed. A pen records the important events in our life.
Let us remember that we hold in our hand the most powerful instrument that man owns. The pen is a magic tool. Whenever you use it, enjoy it.
