    Surtsey was born in 1963.Scientists saw the birth of this island. It began at 7.30 a.m. on 14th November. A fishing boat was near Iceland. The boat moved under the captain's（船长）feet. He noticed a strange smell. He saw some black smoke. A volcano（火山）was breaking out. Red-hot rocks, fire and smoke were rushing up from the bottom（底部）of the sea. The island grew quickly. It was 10 meters high the next day and 60 meters high on 18th November. Scientists flew there to watch. It was exciting. Smoke and fire were still rushing up. Pieces of red-hot rock were flying into the air and falling into the sea. The sea was boiling and there was a strange light in the sky. Surtsey grew and grew. Then it stopped in June 1967.It was 175 meters high and 2 kilometers long. And life was already coming to Surtsey. Plants grew. Birds came. Some scientists built a house. They want to learn about this young island. A new island is like a new world.

New Energy in the Twenty-first Century

Energy from wind

    Wind is a kind of clean energy, and there is lots of it, but, if there's no wind, there is no wind energy.

Energy from the water

    When water from a high place to a lower place, it can make electricity（电） without pollution. However, people have to build dams（水坝） to use this energy, and building dams is very expensive.

Energy from the earth

    There is heat in the rocks under the earth. Scientists use the beat to make geothermal（地热的） energy. This kind of energy is cheap and clean, but it is only possible in a few places in the world.

Energy from the sun

    Solar panels（太阳电池板） on the roofs of house can tum energy from the sun into electricity. Solar power is clean and plentiful（丰富的）. When the weather is bad, it doesn't work.

    When a computer runs a group of programs, it can get very Cooling the computer can cost a lot. So some scientist's wonder what will happen if the heat from the computer can be used.

    Large Internet companies (公司) such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems(系统). These systems send the heat into the air.

    A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-radiator.

    Boaz Loupe, the head of the company, says the e-radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer. So the users don't have to pay to cool their computers.

    Five homeowners in Holland are testing the heating system in their homes.

    "We pay for the computer using, so, in that way, homeowners get heating for free," Boaz says.

    Jan Visor is one of the homeowners. "If you use the computer more the e-radiator produces more heat," he says. "It cannot provide enough heat if you don't use your computer often. "But he is ready to try it. It's a great help for his family.

    The company says e-radiators can produce heat at a temperature of 55℃. It says the system can save its users about S 440 a year.

    What should you do if there's an earthquake at school? How can you protect yourself when you are caught in a stampede(踩踏)?March 28, 2016 provided you with a good chance to learn about safety.

    This day was called the National Day of Education on the Safety of Elementary and Middle School Students(NDESEMSS)(全国中小学生安全教育日). The theme of the day was to give students more knowledge about safety and make sure their lives are safe.

    A survey done by the China Youth and Children Research Center showed that school accidents kill more elementary and middle school students than anything else. The main accidents come from stampedes, earthquakes, fires and sports injuries(伤害).

    What can we do to keep ourselves safe? Staying calm is the first and most important rule when facing accidents. But different accidents have different self-protection advice.

    A stampede is possible anywhere. The larger a crowd gets, the more likely stampedes become. When students around you begin to push, stand still and try to hold onto something, or stay in a corner until the crowd leaves. If you fall down in a moving crowd, cover your head with both hands. Lean to(偏向) one side, curl up(蜷缩) your body and bend your legs.

    Earthquakes are common natural disasters(灾难). When you feel the ground shake, drop down, take cover under a desk and hold on. You should stay indoors until the shaking stops. If you are outdoors, don't stay near buildings, trees or power lines.

    When there's a fire, follow the teachers' instructions, leave the classroom quickly and use a piece of wet cloth to cover your mouth and nose so that you don't breathe in smoke.

A．However, you need to pay attention not to nod too much.

B．Take notes

C．Try to follow up by giving them a call or texting them.

D．It even helps deepen your understanding.

E．Here are a few tips to help you develop effective listening skills.

F．Be Patient

Listening is one of the basic skills. Good communication always starts with good listening. {#blank#}1{#/blank#}

Ask Good Questions

When someone comes to you with a problem, it is natural for you to give them advice. However, instead of giving advice, asking good questions is more important. This can show that you are interested in what people are telling you. {#blank#}2{#/blank#}

Avoid too much Nodding

Nodding while listening to people shows that you are listening carefully. 28．{#blank#}3{#/blank#} If you nod too much, it may make people feel uncomfortable as they may think you are just trying to agree with everything.

{#blank#}4{#/blank#}

You also need to be patient while people are speaking. It is rude to speak while others are still talking. Even if you want the speaker to explain something for you, please wait until they finish their part.

Follow Up

To show your further concern about people, you can go beyond just listening to them. {#blank#}5{#/blank#} It is an act that shows your care and support.

Stamp collecting is becoming a big hobby for young people to remember their trips. Lovers of this hobby enjoy collecting stamps about the places they visit. They usually buy stamps in the local post office. 

 Jenny, a 25- year- old teacher, enjoys collecting stamps. For her, this is a great way to record (记示) her trips. Once during a two- day trip to Beijing, she collected over 90 stamps! They're all about beautiful artworks. 

 Ben, a 12- year- old teenager from Beijing, said collecting stamps helped him learn about the culture and history of a place. He likes to buy different kinds of stamps while travelling. For example, when he went to Xi'an, he bought a special stamp. It has a picture of an old Chinese stone bridge on it. "The stamp looks very marvellous. It makes me more interested in Chinese culture, " he said. Then he started to look for more stamps with interesting pictures. Ben also shares them with his friends. It encourages them to visit more places. 

"These days, more and more tourists share their stamps online. Stamp collecting is a good way to help people know more about the local culture. It's really educational, " said Gina, a teacher from a school of Tourism Management in Dongguan.
