Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. "It's a quite dangerous job," says Giorgio Pezzuto of D' Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.
"The idea is to operate a machine far away that can do the stabilizing job without a human being near,"says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.

    It is said that another acre of the world's forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don't know that in most places the trees won't be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The forest becomes a desert. Then more land will be needed, and more trees will be cut down.
    When the forest is destroyed, it isn't only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish，reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.
    Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world's population is now six billion. Of course, it's very easy to blame the local people. We don't cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now.

It's important to learn about protecting our environment. Here is a 5R rule for us:
1．Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste
2．Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted（融化）and the melted things are made for new coke cans.
4．Recover
When you buy a box of apples, there may be a few rotten（腐烂的）apples, You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a "throw－away" society(社会).But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

What's sleepwalking(梦游)？Sleepwalking usually happens in the first few hours of sleep. Not all sleepwalkers walk when they are sleeping. Some just sit up or stand on the bed. Some even get up and walk around for a few minutes or half an hour. Some do things as if they were awake, but in fact they are not!

Sleepwalkers' eyes are open and they usually go back to beds by themselves. But they won't remember it the next morning.

About 15% of kids sleepwalk. Sleepwalking sometimes happens when a person is ill or worried, or doesn't get enough sleep. If sleepwalking happens often, you should see a doctor. If it doesn't, you don't need to worry. Here are some ways to help stop sleepwalking:

Listen to some music and relax before going to bed.

Go to bed at a regular time every night. keep your bedroom quiet and dark when you try sleeping.

Don't drink a lot of water in the evening and be sure to go to the bathroom before going to bed.

Solar storms shake Earth's magnetic field(磁场). They not only influence human technology, but also animals, reported Forbes.

Studies show that many animals use changes in Earth's magnetic field to find directions. These changes provide the animals a general compass(指南针) for south and north. Animals can also use them as landmarks.

For example, scientists have found special cells in part of a bird's eye nervous system(神经系统). They seem to react to changes in the magnetic field.

Some fish species, like the common trout，have cells with magnetic sensors in their nasal cavity(鼻腔). In 1994 "magnetic sense" was also discovered in sea turtles.

Some whale species may use magnetic sense to navigate (导航) the oceans. A dysfunction of this sense may explain the still mysterious beachings (动物搁浅). Sometimes several hundred animals, such as whales and dolphins, are driven out of water along beaches. They usually can't breathe under their own weight and die slowly.
