We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?

    We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. {#blank#}1{#/blank#}We take minerals (矿物) from the ocean. We can get salt by evaporating (蒸发) seawater. {#blank#}2{#/blank#}such as gold. {#blank#}3{#/blank#}Seaweed (海草) becomes food of many kinds—even candy and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can't drink ocean water. {#blank#}4{#/blank#}But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.

    The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. {#blank#}5{#/blank#}Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.

    We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.

Tom was an eight-year-old boy. He came to a new town with his parents. His family was very rich(富有的). They lived in a big, beautiful house with a big garden. There was a driver, a cook, a gardener and a lot of servants(佣人).

Tom was going to a new school. On the first day, his mother said to him, "Tom, be modest(谦虚的) at school. Don't say we are rich. "Tom said, "All right, Mum. "Then he went to his new school.

He met his new teachers and classmates. The teacher said, "Good morning, boys and girls! This is Tom, your new classmate. Now let him introduce himself to you. "

Tom stood up and said, "My name is Tom. My family is poor. My father is poor. The gardener is very poor. The cook is poor. And all the other servants are very poor too. So I am a poor boy……"

In recent years, Chinese cartoons are catching more and more people's eye. For Chinese cartoon lovers, I Am WhatI Am is a film they can't miss. The film tells the story of Ah Juan, a left-behind child(留守儿童). He lives in a village in Guangdong Province. He's having trouble with his life. He's weak in other people's eyes. One day, after meeting a girl, he comes up with an idea of learning lion dances and joining in a competition in Guangzhou with his friends. They learn lion dances from a former(昔日的) lion dancer and train hard day after day. Things are getting better.

However, here comes the bad news: Ah Juan's father has an accident. Ah Juan has to go to the city and find a job to feed his family. But his love for lion dances doesn't stop. The strong love pushes him to run after his dream once again.

This film is very different from traditional Chinese cartoons. Traditional Chinese cartoons often have to do with Chinese fairy tales(童话故事) or legends. But this film looks at real life. It tells us how a left-behind boy faces up to his hard life. Although life isn't perfect or easy, Ah Juan never loses hope. At the same time, there are many scenes of traditional lion dances in the film. They show this kind of traditional Chinese culture to more people.

About 1.2 billion people around the world are learning a foreign language. However, not all of them enjoy 1 . We talked to hundreds of successful language learners. They shared some of their habits with us.

One key 2 long-term success is working towards the goal（目标）all the time. Most successful language learners make sure they 3 a few minutes practicing every day. Some language learners practice their language only in class. In the long run, they show much slower progress than those who practice 4 .

The second habit of successful language learners is that they don't study too much or too long at a time. 5 , they study for a short period of time each time. And then after a break, they continue. Over a longer time, they make 6 .Some language learners always want to learn as much new material as 7 . But it has been proved that one slowly forgets 8 he or she has learned over time.

Let's be honest: Do you still remember all the English words and expressions you learned last year? Successful language learners 9 the old material regularly （规律地）. Regular review turns your short-term memory into a long-term memory.

Are you having a hard time improving your English? Then you may try to 10 these three habits. Don't worry if it takes time. Learning a second language well is a long-term process—it should take time!

Scientists say they recently invented the world's tiniest remote—controlled robots. The robots are small enough to sit on the side of a coin. They don't have any power of their own，and they can be controlled from a distance by using lasers（激光器）. The scientists say one day robots like these may be able to work in areas too small for tools. The robots don't move very quickly. But because of their tiny size，they're also not too slow. It takes the robots about 20 seconds to cover 1 centimeter. 

Right now the robots aren't all that useful. All they can do is to move，and they need to be in a place where lasers can shine on them to do that. But the scientists say these robots are an important step toward inventing more helpful tiny robots. 

The researchers say that one day tiny robots like these might be able to work in very small spaces. It's possible that they could build very tiny machines，or perhaps even travel inside the human body to help do with medical problems. 

Using similar building methods，the scientists made a number of different robots，including ones that looked like small insects. John Rodgers，says that their methods allow them to "build walking robots with almost any sizes or 3 D shapes. "
