Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sports, and simply because they were in the way. Thousands of kinds of animals have disappeared from the Earth forever. Hundreds of animals are on the danger list today. About 170 kinds in the United States alone are considered in danger. Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers' stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

   Fire can help people in many ways. But can also be very harmful. Fire can heat water warm your houses, give light, and cook food. But fire can burn things too. It can burn trees, houses, animals, or people. Sometimes big fires can burn forests.
    Nobody knows for sure how people began to use fire. But there are many interesting, old stories about the first time a man or woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope and brought fire down.
Today people know how to make a fire with matches. Children sometimes like to play with them. But matches can be very dangerous. One match can burn a piece of paper, and then it might burn a house. A small fire can become a big fire very fast.
   Fires kill many people every year. So you must be careful with matches. You should also learn to put out fires. Fires need oxygen. Without oxygen they die. There is oxygen in the air. Cover a fire with water, sand, or in an emergency, with your coat or something else. This keeps the air away from a fire and kills it.
   Be careful with fire, and it will help you. Be careless with fire, and it will burn you.

    Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.
    Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person's thoughts.
    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
    “Our brain has billions of body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”
    The scientists designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain.
    Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair.”
    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long.

Compared with other European countries, lifestyle in Italy is slower and more relaxing in its own way. Italians love to chat over a cup of coffee, go out for a walk in the middle of the day, and enjoy long lunches and dinners.

The family is important to Italians. They can't think of spending a day without talking about their parents and children, or a weekend without a family lunch or dinner. Italians living outside their country miss their family a lot.

Italians like simple life. Their days start and end with a cup of coffee. A cup of coffee after every meal is a must. Italians love to spend time over a hot cup of coffee and even hotter conversation with friends. Topics are usually about family, football and politics(政治).

Sport is a very important part in lives of many Italians. Football is their favorite sport. There are hundreds of football clubs with top football teams in Italy. Also, many top players from all over the world play in Italy. Volleyball is also popular and so is rugby, with the top rugby team playing for the European Challenge Cup.

Every Italian province, city, town and street has a historical event that took place there and the Italian calendar is filled with national holidays that they love to celebrate.

Songs help memories

The power of music

Most people can remember important news stories clearly, whether it was the murder of President Kennedy in the US or 9/11.But now psychologists Martin Conway and Catriona Morrison, from the University of Leeds in the UK, are investigating how music can create “autobiographical memories” of the main events in our lives. The study is online. People have to choose a song by the Beatles and describe the memories that they have when they listen to it.

Reminiscence bump

Morrison explained that they looked at different age groups and their memories. We often remember more from when we are teenagers and this is called “the reminiscence bump”. This is the time in your life when you form your idea of who you are. For older people who have memories related to the Beatles' music, most of those memories are from when they were teenagers. But younger people also had clear personal memories from their past.

She loves you

This study was different from other memory studies, because people remembered events from their past with lots more details. Morrison explained: “It was like people had travelled back to the past, and they had very clear memories of things that had happened. When they heard a song like She Loves You by the Beatles, they could remember one night in autumn 1963.They remembered what they were wearing, what the weather was like and what their friend said to them. You get a lot more information than if you just say, ‘tell me about a night you remember'. ”

The study has found that music could be used with people who have problems remembering the past. “You could use music to help improve people's ability to remember,” said Morrison. “In the future, we would like to do more experiments to see how useful music is in helping people to remember the past, and compare it to other things that might also help.”

Some scientists say that animals in the ocean are increasingly threatened(威胁) by noise pollution caused by human beings. The noise that influences sea animals comes from a number of human activities. It is caused mainly by industrial underwater explosions(爆炸) , ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.

Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety five would have the same effect（效果）.

Some scientists have proposed setting a noise limit （限度）of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales（鲸鱼）.

A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed.

Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. It's time for them to take action to help ocean animals.

Give your dead batteries a new life. Recycle them！

Batteries(电池) are used to power clocks, computers, tools and more. However,

Your batteries have some serious power when their lives are over.

WHY TO RECYCLE BATTERIES

Remember, batteries are harmful waste. This mean you could properly throw away. You may not think one little battery can cause that much pollution. But don't think of it as just one battery—there can be millions. In Canada, each person uses about 20 single-use batteries every year. That's about 700 million batteries! If all these batteries end up in landfills(垃圾填埋场), the heavy metals inside them can get into the water, land and air. It can be harmful to humans and wildlife.

By recycling single-use batteries instead of throwing them away, you can cut down pollution and also help save energy. All batteries are mainly made of plastic and valuable metals. Through recycling programs, dead batteries can be changed into something useful like steel products, or even new batteries!

HOW TO RECYCLE BATTERIES:

Make a difference by starting to collect batteries at your home or school today. You can prepare a box for battery collection and invite friends, family and classmates to bring in old batteries to be recycled.

There are many safe ways to deal with your batteries. You can:

Find a Call 2 Recycle public collection station near you.

Ask the store where you bought the batteries if you can return them there.

Communicate with your local city government to find out if there are special programs for recycling used batteries!
