Why do plants grow in some places and not in others? Why does some land have so much 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(沙漠) everywhere 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(土壤) 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 this beach has almost no plant food.

Several days ago, while I got online, my cousin’s QQ head popped out(弹出). We hadn’t seen each other for a few months, so I decided to start a talk with her. My cousin is studying in a college of our city. Her hobby is surfing the Internet. Every time I am on the computer, she is always online, listening to music or decorating her “personal space”. I like visiting her space. It’s creative and modern. I can’t design such a colorful web page as hers.

When I read the sentences she sent to me, I noticed that the Chinese characters had been changed, but I could still guess their meanings. I took a strong interest in this type of new characters. Further watching made me realize that they added some common Chinese radicals(部首) to the original characters, making them more vivid(生动), a little like Japanese. My cousin said this gives new life to the Chinese language and culture.

It is true that the Internet has reinvented our language, but I still can’t accept this new change. Some Chinese characters have meanings in the shapes; one shouldn’t superficially (浅薄地)change them by adding an additional radical. So I advised my cousin to change her new idea and use standard characters to communicate. And she willingly accepted my advice.
