There is a saying that, “Earthquakes don’t kill people, but buildings do.” It seems sadly true. Tens of thousands of people died under bricks(砖)of the damaged(毁坏的)buildings in Turkiye and Syria during the recent earthquakes. Is there a way to build earthquake-proof buildings? Engineers have some life-saving ideas.
To prevent earthquake waves from going through the building, one way is to “lift” the building’s foundation(地基)above the ground. The building can be built on top of pads(热状物), which are usually made up of steel and rubber (橡胶). During earthquakes, only the pads move and the building stays steady.
Earthquake proof materials must be easy to ben(弯曲)without breaking. Some of these materials include steel, wood(合金)and bamboo. In Japan, most traditional houses are built with wood instead of concrete(混凝土), wooden buildings bend to avoid building up stress.
Triangles(三角形)are very strong shapes. When a force comes to one of the corners of a triangle, it will be reduced by going down each side. When the two sides of the triangle are squeezed(挤压)), they lean(倾斜)on each other. During earthquakes, triangles can hold the building together when it shakes. Many earthquake-proof buildings use this shape in the design, both inside and outside the structure.
US company Arx Pax is developing magnetic field(磁场)technology that can raise houses above ground when earthquakes happen. When the sensors in the home feel earthquakes, they will tell “hover engines(悬停引繁)”. These will create an opposing(相反的)magnetic field to lift the house off the ground. Maglev trains use similar technology, so the company believes it can be used in buildings as well.
Japanese company Japan Dome House has made dome shaped(四顶状的)houses with Styrofoam(泡沫塑料). Styrofoam is a very light material. The whole house weighs only 80 kilograms. So when earthquakes happen, the house will not hurt people.

I’ve been working in a school for more than twenty years. Many parents often ask me, “How can you teach your child good study skills? How can he or she get the homework done as quickly as possible?” Here are some tips:
1. If the child is as young as nine or ten, ask him or her to prepare a small notebook to write down the homework given by his or her teachers. By developing this habit, he or she will learn to be much more responsible(负责的).
2. Find a good place to study. This should be a quiet place that is free from everything but study things. No games, radios, or televisions. Once you have decided on a place to study, this should be the only place where your child does his or her homework and studies. There should also be a very specific time for homework to be done. Usually, homework should be done as soon as the child gets home from school. This also goes for the kids who take part in after-school activities. Of course, it is a good idea to allow the child to have a healthy snack before the work begins.
3. Also remember, that it is the child’s duty to do his or her homework. Some children give up easily and go to Mom and Dad for help when they have a problem. Try to let them solve it first. By doing this, they will get a sense of success from overcoming problems. In this way we help them to help themselves.

Studies say that people nowadays have more free time than ever before. Then why doesn’t it feel that way? These days, our free time is usually spent watching television, using computers or communicating on our phones. To really help us increase our energy levels, it is important to use our free time wisely.
Set up your goal. Think about what you want to achieve in your free time. Do you want to get fit, get creative or simply relax? Don’t worry about what you should do. Just think about what will make you feel more satisfied.
Set a date. Plan when you are going to enjoy your free time, and treat it in the same way as anything else on your calendar. If something else more important comes along you can choose whether or not to postpone it, but never cancel it!
Do what you want. Many people worry too much about their free time activities. They want to do things that will make their friends surprised, or help them get a better job. But free time isn’t about that. It is about doing an activity for fun, so don’t let outside pressures influence your choice.
________ You’ll really know you’re using your time wisely if what you’re doing helps other people. So find out what’s going on in your community and lend a hand. Visit the elderly or help out in a children’s club. If socializing is not your thing, why not volunteer for a wildlife organization?
