Do you know how to plant a tree? Once you've chosen a tree, you'll need to prepare your place for planting.

Planting the Tree

Dig a hole a foot deeper than and twice as wide as the root ball of the new tree. Loosen the soil at the bottom and sides of the hole, so roots will be able to easily enter the soil.

Gently remove the tree from the container and guide the tree into the hole. Build soil up and around the roots if necessary, so the tree is at the same soil level as it was originally grown.

Straighten the tree in the hole. Before you begin filling, have someone view the tree from several directions to confirm that the tree is straight. You should fill the hole with existing soil that has been mixed with rich materials. At this time you can also add bone meal and then water the tree.

Caring for the Tree

Caring for the tree once it is planted is an important step so you should provide regular watering. Always feel the soil before watering, as over­watering can also harm the tree. When soil is dry below the surface of the covering, it's time to water. You will probably need to water at least once a week.  Continue until mid­fall, when lower temperatures call for less­frequent watering.

When to Plant a Tree

Now that you know how to plant a tree, the next step is deciding when to plant. Spring and fall are generally the best times to plant a tree. This gives the tree time to adjust (调整) before summer heat or winter cold arrives. In areas without cold winters, trees may be planted during the winter.

Is there anything more important than health? I don't think so. "Health is the greatest wealth，" wise people say. You can't be good at your studies or work well when you are ill.

If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X­rayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.

Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: "Eat with pleasure, drink with pleasure and enjoy life as it is. " The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man. "But you know, doctor，" he said, "it's not easy to begin smoking at my age. "
