Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.

　You probably know how to ride a bike safely. Now learn to use a computer safely.

Your eyes

　Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.

　When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.

Your hands and wrists (手腕)

　　Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows (肘部） at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.

Your back

　　Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms（前臂）, wrists, hands and the upper（上部） part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.

　Enjoy your computer, but use it safely.

Dear Mom,
I'm sorry that I can't go back home for Mother's Day next week. On that day, I'll have to go to an important meeting for my boss, who helps me a lot with my work and life here. But I'll find time to see you at home soon.
Mom, thank you for everything you've done for Tim and me. After Dad died ten years ago, you had to work in a supermarket in the daytime and in a restaurant at night. But you always gave us two your love and care. You don't have to work now, but I still remember your coming home and feeling tired many evenings.
Tim is going to finish his studies next month. He said he would move back from school and look for a job near home. I'm glad you won't live by yourself any more. Let's plan to take a trip in the near future. It's been years since the three of us took a trip together.
Happy Mother's Day. I love you!
Best wishes
John
【小题1】 What can we learn about John's mother?

Growing mushrooms（蘑菇）is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.

Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.

When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don’t have enough time to spend taking care of everything yourself, some helpers may be the best choice.

After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides（农药）or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence（围栏）or a gate so that only you and your workers can get in and out.

Mushroom growing is not difficult and it is easy to get stared in the world of farming. You will soon possibly be able to provide some of the great cooks of the world with high quality mushrooms that will be enjoyed by thousands of people all over the world.
