　　Why do plants grow in some places and not in others Why does some land have so many plants growing on it, while other land has almost no plants growing on it at all
　　To grow, plants need several things. One is warmth. In very cold places, almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why dry deserts are almost not covered by trees or grass.
　　Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.
　　Another thing plants must have before they can grow is food. What will happen if we try to make things grow on the sandy beach A few plants, such as beach grass, will grow in sand, but most plants won't. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on the beach has almost no food for plants.

　　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.

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(实用的). We cannot sign a bill or write a letter or buy a house without a pen. An agreement is worthless till the 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 own names are written on the name list with a pen. We cannot be married till we have signed. A pen records the important events in our own life.
　　Let us remember that we hold the most powerful instrument which man owns in our hand. The pen is a magic tool. Whenever you use it, enjoy it.
