Make a Rainbow (彩虹)

Keep the mirror in the water glass We all love the rainbow after the rain. So, it’s a better idea to make a rainbow by ourselves. We need water, glass, a small mirror and sunlight.

Steps: * Make sure it’s a sunny day. * Fill the glass with water. * Place a table in a dark room in front of narrow (窄的) sunshine. * Now put the water glass on the table so that sunlight can pass through the water. * Now, keep the mirror in the water glass on the table. *Set the right angle (角度) between the mirror and the light to get a beautiful rainbow on the wall.

Are you a shy person? Do you expect to become outgoing? Being outgoing can help a lot in your life. In fact, being outgoing is not so hard as you think. Here is some advice on how to become outgoing.

You can start to try becoming outgoing when you stay with your friends. But the real challenge（挑战）comes when you meet strangers or new friends. Smile at them, and usually they will smile at you, too. You may find it easy to start talking in this way.

Start a talk positively （积极地）. Try to speak first. Simple greetings such as “Hello!” “How is it going?” and “It’s a little cloudy today, isn’t it?” are a good start. After that, you can talk more. For example, you can talk about the latest news. But you’d better read some news in newspapers and have your own ideas first. Or you may find that you won’t have much to say.

There is no better way to become outgoing than going out. It is also a very important step. Usually those who like to do the same things can communicate （交流） better. If you like playing sports, go to a sports club. You may make many new friends there if you get over your shyness.

【小题1】It's easy to hurt your back muscle (肌肉) when you try to pick up a heavy thing. However, there is a correct way to lift things from the floor. If you pick up heavy things correctly, you probably will not hurt your back. To lift something from the floor correctly, first bend your knees and lower yourself .【小题2】 Don't bend over from your waist (腰), and keep your back and hips (臀部) and waist in a line. If you bend over, the muscles in your lower back can become hurt very easily. If your back and hips are straight, the muscles are stronger, because they hold up together. 【小题3】 As you lower yourself, try to get as close to the thing as you can, put one knee on each side of the thing. Remember at all times to keep your back straight. Put your hand under the thing that is in front of you, between your knees. 【小题4】 Use your leg muscles in order to stand up. In other words, lift with your legs, not with your back.
