That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can tell how heavy the glass it. When you feel all these about the ball, you really see it.
With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pockets. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it.
The bottom of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them.
Most museums are just for looking. But today some museums have things for visitors to touch. Their signs say, “Do touch!” there you can feel everything on show.
If you want to see better, reach out and touch. Then you will really see.

Cellphones play an important role in our daily life, such as keeping in touch with others, calling home or the police if there is any emergency. Although cellphones can help us a lot, we must think of others when we use them. Unfortunately, some people do not consider others when using their cellphones. For example, some cellphone users speak too loudly and discuss personal matters in public places. Some people make phone calls in the cinema. Some people talk for a long time on the phone while they are driving on the busy road. Someone’s cellphone will ring during an important meeting. Many people complain about these bad manners. In their opinion, cellphone users shouldn’t disturb others when they make a call.
Then how to use a cellphone politely in public? The following rules will help you. When you’re in a meeting, watching a movie or having a lesson, you’d better turn off your cellphone. When you get a call and you’re with friends, try to make the call as short as you can. If you are waiting for an important call, then make sure that you tell others about this at the beginning of a meeting. It’s rude to scream(尖叫声) or shout on the phone. Make sure you will be heard only by the caller but not by the others around you. Besides, if possible, find a quiet place where you can talk in private.

There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.
