There is a saying that “earthquakes don’t kill people, buildings do.” It seems sadly true. Thousands of people died under bricks (砖块) of the damaged (毁坏的) buildings during the recent earthquakes. Is there a way to build earthquake-proof (抗震) buildings? Engineers have some life-saving ideas.
“Lift” the house up
To prevent earthquake waves from going through the building, one way is to “lift” the building’s foundation above the ground. The building can be built on top of pads (垫状物), which are usually made up of steel and rubber. During earthquakes, only the pads move and the building stays steady (平稳的). This can reduce the strength of earthquake waves by 13 to 15 percent, according to the website Bethinking the Future.
Right materials
Earthquake-proof materials must be easy to bend (弯曲) without breaking. Some of these materials include steel, wood and bamboo. In Japan, most traditional houses are built with wood. During earthquakes, wooden buildings bend to avoid building up stress. Steel is one of the main materials of modern tall buildings because it can increase their ductility (延展性).
Dome house
A Japanese company has made dome-shaped houses with styrofoam. Styrofoam is a very light material. The whole house weighs only 80 kilograms. So when earthquakes happen, the house will not hurt people.
Besides, there are many other good ideas on building earthquake-proof buildings. For example, a company in America is developing magnetic field (磁场) technology that can raise houses above ground when earthquakes happen. We hope these ideas can be put in action and more people’s lives can be saved.

【推荐2】There's a heat that's so hot you can literally(不加夸张地) fry an egg in the sun. This is a serious side to summer in Australia that you might not know about.
In February there were more than 80 different bushfires burning at the same time in New South Wales, a southeastern state of Australia. The Guardian newspaper reported that 42 homes were burned to the ground because of these fires. These homes are not like Chinese ones. They are huge farms. Many Australian properties are larger than 1,000 sq km, while the biggest is more than 20,000 sq km, even larger than Beijing!
Every family prepares for bushfire season and protects their property. But sometimes the fires are too big and people have to move to safety
The hot weather also causes other problems. It was so hot in February that thousands of bats(蝙蝠) died from the heat. People can get sick if they stay outside for too long or don't drink enough water The heat can also cause power problems for homes and businesses
The heat, which can go above 40 ℃ in some cities, is very dangerous. There are lots of trees and dry grass in areas far away that can easily catch fire. Even throwing a burning cigarette out of a car window can start a dangerous fire. That is why summer is also known as "bushfire season" in Australia.
The Australian summer is enjoyable. But it is worth remembering that the heat can cause lots of problems, too.

Tim: Today, we are talking about forest fires. Our reporter, Penny Wang, is in Indonesia (印度尼西亚).
Penny: It is now three o’clock in the afternoon but I can’t see the sky. Thick smoke is covering most of South-East Aisa. It is causing thousands of people to have eye or breathing problems. Some people may even die.
Tim: Why don’t firemen put out these fires?
Penny: The firemen can’t put out the fires. They are too big. Only a lot of rain can put them out. But the weather is very dry here and it may not rain for a few weeks.
Tim: How did these terrible fires start?
Penny: They were started by farmers. They use fires to clear the land before they plant new crops (农作物) such as rice. Also, a drought (旱灾) started many months ago, so the land is very dry.
Tim: What other problems are the fire causing?
Penny: Well, of course they are very bad for people’s health. And no tourists are coming here. People don’t want to take a holiday in a bad environment. But the most serious (严重的) problem is that fire is destroying the forests. They are thousands of years old. As you know, trees are very important to the world and now millions of them are burning. This will cause air pollution in many other places.

【推荐1】The right name is important in the business world. All you have to do is think of the names for some of the products you buy every day and you’ll agree that the name and the product are connected in the everyone’s mind.
In many countries, successful trade or brand names are protected by law. This is so that other companies cannot make a product and, in fact, be buying something different. Businesses register a company or a product name with the government. In fact, more than 1,000 product and company names are registered every hour. Many companies spend a lot of money to find the right name for their products. A good example of this is. In the car industry, some successful names for cars have powerful associations (联系). The Ford Mustang and the Jaguar are only two examples of choosing the names of animals that are fast and strong.
When a U. S company decides to sell its product in another country, it has to make sure that the product name translates properly. When Coca-Cola introduced its soft drink to China, it looked for the right name. It wanted a name that would do two things. One was to present its image(形象)in Chinese and the second was to be close to its first brand name—Coke. It took some efforts before finding the right word —which sounds similar and translates as “happiness in the mouth”. Asian company names are not new to the United States. The brand names of Samsung and Sony have been successful. Finding the right brand name is a big business. Asian companies that sell to foreign markets pay to find a name that will connect with its customers. There are even naming companies that specialize in inventing product names. These companies can charge (要价)up to $100,000 a word for their creations. But it’s worth it. Successful companies know how important the right brand names are for their development.

B.To help people choose the best products |
C.To present good images of the products. |

【推荐2】April 22 is Earth Day. Everyone on earth should care about and protect the earth!
The earth has warmed by about 1℉(华氏度) over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer.
First, greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.
When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one mere by 2100.
People can affect the earth’s air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.
1. Earth Day is probably set for people to ________.A.learn less about the earth | B.make full use of the earth |
C.take better care of the earth | D.study the warmth of the earth |
A.not very clear | B.completely secret | C.well known | D.not given yet |
A.sea rising | B.climate change | C.nature’s unbalance | D.people’s activities |
A.animals and islands | B.climate and the warmth of the earth |
C.fridges and animals | D.sea level and the growth of plants |
A.there is more rain now | B.we should protect the earth |
C.we must stop pollution | D.sea level is getting higher |
A. Don't be crazy about computer games. Play them just for short time when you are tired. B. Make a plan for study and hobbies. Find time to relax as possible as you can. C.

【推荐1】When you’re having a hard time with something, it’s natural to turn to others for help. Getting help sounds simple, but it’s not always easy to do. Sometimes certain beliefs or ways of thinking can make it hard to ask for help. Here are some kinds of attitudes that can stand in the way and ideas on how to get past them.
Some people believe that needing help is a sign of weakness. Actually, it’s a sign of strength, not weakness. You know what you need and you shouldn’t be afraid to reach out for it. Once a boy told me he wanted to ask his coach how to improve his basketball skills, but he was afraid that his coach might think he shouldn’t be on the team. In fact, when he asked his coach for help, his coach thought he was practicing hard.
Some other people think they don’t deserve(应该得到) help or support. Everyone needs help now and then. Accepting help can strengthen friendships and relationships. Everyone feels good when they can support a friend. For example, if you want to find out how Katy solves problems with her parents, you should ask Katy if she has time to talk and tell her how important her viewpoint is, instead of worrying that Katy is too busy to help you. When you ask for help, choose someone who listens and cares, not someone who judges or criticizes you. If you get refused, it's not because of you, but the other person. So tell yourself: If Katy says no, she might not be ready to talk about her own experiences.
Another wrong attitude is waiting for someone else to make the first move. It’s not always easy for other people to see when you need help. Maybe you’re putting on a cheerful face to hide the problem. Don’t wait for someone to read your mind. You have to ask.
Because it can be hard to reach out for help, don't hesitate(犹豫) to offer support to another person if you think he or she needs it. Giving and receiving help are great life skills to learn. They help us improve our abilities to understand other people.

Sciences
Ask students what is the most difficult course, and most of them will give you the same answer: mathematics. This is also true for Dai Shuang, a 14-year-old student at No.1 Middle School. He says, “It’s so difficult that I get a headache whenever I think about the math exam.”
According to Dai, studying this course is not easy. He usually studies math by himself and spends most of his free time reading math books and doing exercises.
Solution
Qin Xia, a math teacher, offers some advice. “Most students fear mathematics because they think the class is too difficult or boring.” he says, “These students don’t listen carefully in classes or even sleep.” In Qin’s opinion, they can try to take notes. And they’d better ask teachers for help. It’s difficult for students to teach themselves math, which will waste a lot of time. Besides, doing a lot of exercises is also important.
