Imagine you are taking a walk on the beautiful beach. Just then, your feet step over something and you hear a crack (噼啪声) —an empty plastic bottle. Things like this are happening more often because of sea rubbish.

    Studies show that 80% of all the waste is from the land. The waste is mainly plastics (塑料制品) which are really hard to degrade (降解). So the rubbish will remain there for a long time. Some of the pollution is caused accidentally. For example, about 10,000 product-filled boxes are lost at sea every year from business ships. Sometimes people just throw things into the water from boats or land. Many large rubbish areas are formed in the North Pacific Ocean.

    Thankfully, the situation isn't ignored (忽视). Groups like the National Oceanic and Atmospheric Administration (NOAA) are taking action to help clean the sea. Since 2006,76 projects have cleared out 3,814 metric tons (公吨) of rubbish from the sea. Methods of rubbish cleaning include using machines to remove (移除) the waste away from the surface of sea water. Besides, special nets are set by the mouths of rivers to stop the rubbish before it reaches the sea. If everyone does his part, sea rubbish seems like a problem that can be solved.

Once a man walked to India where he had never been before. When he got there, he saw many kinds of fruits. But most were expensive. The man saw a big basket of red, long fruit. He thought it must be sour and sweet. 

He went up and asked, " How much per kilo?"And the shopkeeper said, "Two rupees(卢比). "

Two rupees in India is nothing. And it was the cheapest in the shop. So he bought a kilogram and started eating it. But after he ate some, his eyes watered, his mouth watered and burned, and his face became red. He even coughed while eating. 

But he still ate the fruit! Some locals who were looking at him shook their heads and said, "You're crazy, man. It's chilly! You can't eat so much! People use it as spice(调味品), but only a little bit to put into food for taste. They're not fruit!" But the man said, . "No, I can't stop! I can't waste my money. "

Do you think that man was stupid? In fact, we sometimes do a lot of things like that. We put money, time or effort into a relationship, business or job. Even though over a long time it won't work, and we know things will never change in the future, we still go on just because of the things we've put in. like the man. 

So even if you've lost something, let it go and move on. That's better than keeping losing. 

On a hot day，Dog finds a tent on the beach."Cool! "he says."Now I can stay away from （躲避） the hot sun."And he walks inside. 

"Hey，Mouse!Come and see the tent I find，"says Dog. 

"Thank you!It is a great place to stay away from the hot sun，"says Mouse，and he walks into the tent. 

"Hey，Cat!"call Dog and Mouse."Come and see our tent.It is a nice place.""Thanks，"says Cat when he walks inside. 

"Hey，Chicken!"they call."Come into our tent and cool off! ""Thank you，"says Chicken.and he walks inside. 

"Hello，Elephant!"say Dog，Mouse，Cat and Chicken."We would like to ask you to come into our tent，but there is no more room.We are very sorry." 

"I am sorry for you，"says Elephant."You see，this is not a tent.It is my hat.""Oh，"says Dog."We will look for a tent somewhere else.""That's OK，friends， "says Elephant."We can share （分享）it! "
