It's hard to make friends if you stay at home all the time, so get out of the house and do things that will put you in touch with(接触)other people. It's easier to make friends with them when you find you like the same things as other people.

Don't be afraid to show people what you're really good at. You can talk about the things you like and do best. People will be interested in you if they, hear something interesting about you.

    Look at people in your eyes when you talk to them. That way, they'll find it easier to talk to you, or people may think you're not interested in them and may stop being interested in you.

    Be a good listener. Let people talk about themselves before talking about "me, me, me” You can ask people lots of questions and show that you are interested in their answers.

    Try to make friends with the kind of people you really like, respect(尊敬)and admire(羡慕). You shouldn't just make friends with those people you will meet them easily. Try to be friendly with all kinds of people. That way, you'll have a bigger group of people to choose from. Then you'll be easier to make friends with other people.

Grace has a large glass jar(罐) and she got it from her grandfather. The girl 1 it half full with clean water. The water shone 2 in the sunlight. Each drop was proud of its own purity(纯净).

One day, Grace's cousin, Bob, came for a 3 . While Grace was away, the boy saw the jar and thought, "What will happen 4 I put some ink(墨水) in the water?"

Bob searched Grace's desk and found a crayon. Just as he was going to put a few drops of ink in the jar, Grace walked in. "Bob, what are you doing?" She asked. But it was already too 5 . Grace watched in anger as the ink slowly mixed in, 6 the water blue.

"Don't you know that once a jar of water gets 7 , it's very hard to get it clean again?" Grace sounded 8 .

"I'm sorry," Bob replied in a low 9 . "I was just curious（好奇）."

Grace 10 to get the water clean, but the jar was too heavy for the two of them to lift up. 11 could only pour some pure water into it. The jar of water would 12 be as clean as it was before.

The world's oceans(海洋) are just like this jar of water. Once we 13 them, it will be very difficult, if not impossible, to make them clean again. Unluckily, some people and countries don't seem to 14 this. They've poured many dirty or even toxic(有毒的) drops into the world's "jar". But 15 Bob, they are not curious.

In the warm waters near an island, a small group of dolphins comes up for air. The dolphin in the front is Mother Dolphin.

Mother Dolphin will 1 Baby Dolphins for a long time. She'll stay beside her babies until they grow up. Baby Dolphins are very playful. They can swim well and love to push their mother softly. After playing so much, they get tired. At night, they 2 just below the surface of the water with Mother Dolphin.

Dolphins may look like fish, 3 they aren't really fish. Dolphins have their own underwater language of sounds. They use these 4 to communicate with each other.

Dolphins always travel in small groups to 5 themselves against their enemies, like the shark. They can live for many years. Some dolphins live up to 35 years in the wild.

Students sometimes fight (打架) at school. But how can you keep away from a fight? Here's something you can do. 

Be calm (冷静). Sometimes, you feel so angry that you really want to teach somebody a lesson. But being angry can't solve problems. A fight can't help, either. It may bring you more problems. In the school, everyone will be punished (惩罚), if he gets into a fight. There is no winner in a fight. 

Shout loudly. If you know someone is coming up behind you to attack, turn to the person with your hands up in front of your body and loudly say"stop" before walking away. Loud voice can usually make the attacker calm down. If the person doesn't stop, shout for help by calling your teachers. 

Learn to say no. Your friend may ask you to join in a fight, but helping him fight is not really helpful to him. If you really want to help him, try to ask him to stop. Also, you can tell him that if he has a fight, he may be punished. Then, try to know why he wants a fight and help him find a right way to solve the problem. 

If you follow my advice, you may keep away from a fight at school.
