temperature of earth"s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the
same way in every area of the planet. But scientists think that the rise in average temperature is already
affecting the earth"s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more
trash, and polluting the environment which are some of the reasons why the temperature has gone up.
Many scientists believe that the biggest causes of global warming are new human technologies that
release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide
and methane, making it hard for heat energy to go into space. In the past, the climate didn"t change much
because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can"t be blamed on nature. Ever since
the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those
machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human
activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric
temperature has already damaged the environment. Sheets of ic
e, called glaciers, are melting inAntarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding
warm water to the oceans and causing the sea level to rise.
Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along
the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other
weather problems caused by pollution in the atmosphere. Some places have received more rain, others
have had bigger storms and a few areas in the world have experienced unusual droughts.
1. What is mainly talked about in this passage?
A. The melting of glaciers.
B. Global warming.
C. The world"s weather.
D. The earth"s temperature.
2. What causes global warming according to scientists?
A. Human activities.
B. The nature itself.
C. The earth"s atmosphere.
D. New discoveries
3. From the passage we can see that global warming will bring about _____.
A. the pollution in the atmosphere
B. natural disasters
C. population pollution
D. the rise of glaciers

Everybody gets stressed time to time. 1 Some ways of dealing with stress -like screaming or hitting
someone一don"t solve (解决),much. But other ways, like talking to someone you trust, can lead you to
solving your problem or at least feeling better.
Try taking these four steps. the next time you are stressed:
(1) Get support. When you need help, reach out to the people who care about you. Talk
To "trusted adult, such as "parent or other relatives. 2 They might have had similar problems, such
as dealing with a test, or the death of a beloved pet.
(2) Don"t take it out on yourself. Sometimes when kids are stressed and upset they take it out on
themselves. Oh, dear, that"s good idea. Remember that there are always people to help you. Don"t take
it out on yourself. 3
(3) Try to solve the problem. After you"re calm and you have support from adults and friends, it"s time
to get down to business. 4 Even if you can"t solve it all,you can solve a piece of it.
(4) Be positive. Most stress is temporary(暂时的).Remember stress does go away,
especially when you figure out the problem and start working on solving it. These steps aren"t magic, but
they do work. And if you can stay positive as you make
your way through a tough time, you"ll help yourself feel better even faster. 5
A. Ask for a helping hand to get you through the tough situation.
B. Notice your friends" feelings and find a way to help them.
C. Different people feel stress in different ways
D. Ah, it feels so good when the stress is gone.
E. You need to figure out what the problem is.
F. And don"t forget about your friends.
G. Then, find a way to calm down.
disabled people control their wheelchairs. The key is a device that is put in the ears and listens for tongue
clicks and then translates the sounds into commands for a wheelchair.
Mouth interfaces (接口)that interact with wheelchairs are already common for seriously disabled
people. One device that fits within the roof of the mouth houses buttons that can be pressed with the
tongue.
"But everything that involves tongue movement requires putting something in the mouth," says Ravi,
from the University of Bristol, UK. Besides issues of hygiene (卫生),these devices make it difficult for
the user to eat or speak, if they are able to ,while using it. Monitoring tongue movements through the ear
avoids these problems.
The new device, a simple microphone that looks like an earphone for listening to music, picks up
certain sounds made by four sorts of tongue clicks. The microphone sends the information to a signal
processor which sorts out the clicks and passes the information to the wheelchair, where each click type
moves the chair in a distinct direction.
Ravi"s group has used the interface to control a virtual wheelchair. They have also used it to control
the reaching and grasping movements of a robotic arm. The four tongue clicks can be mastered in a
couple of hours, say the researchers. "This is a promising technique," says Jose del R. Millan, who has
been working on brain interfaces for controlling wheelchairs at the Swiss Federal Institute of Technology
in Lausanne. If it can be combined with real wheelchairs and shown to work reliably it could be very
valuable for patients, he says.
The researchers plan to start using real wheelchairs, but in the meantime they are looking at whether
the number of commands can be increased by using a microphone in each ear, to get clearer signals to
the wheelchairs. "Even if four clicks prove to be the limit, it only takes 0.2 second to detect each sound,
so it"s possible to spread high-level commands through combinations of clicking sounds," the researchers
say.
B. The device.
C. The wheelchair.
D. the brain.
B. The device is dirty and leads to disease.
C. The device makes it difficult for people to eat or speak.
D. People are disturbed by the device when listening.
B. It hasn"t been put into practice to control wheelchairs.
C. It can pick up all sounds made by tongue clicks.
D. It can give orders where the wheelchair should go .
B. That it needs a long time to detect each sound.
C. That it can only combine some easy tongue clicks.
D. That it takes a long time for the disabled to learn tongue clicks.
First, eat different foods, especially fruit and vegetables. You may have a favorite food, but you"d
better eat something different; if you eat different foods, you will probably get more nutrients your body
needs.
Second, drink water and milk as often as possible. When you"re really thirsty, cold water is th
e NO. choice. Lilk is a great drink that can give you more calcium your body needs to grow strong bones.
Third, listen to your body. How do you feel when you are full? When you are eating, notice how your
body feels and when your stomach feels comfortably full. Eating too much will not make you feel
comfortable and make you fat.
Fourth, limit screen time. Screen time is the time you watch TV,
DVDs and videos, or using computers.It is good to take more exercise such as basketball, bike riding and swimming. You can"t watch TV for
more than two hours a day.
Fifth, be active. One thing you"d like to do as a kid is to find out which activity you like best. Find ways
to be active every day.
Follow these rules and you can be a healthy kid.

In 1963,former Senator Gaylord Nelson began to worry about our planet. Nelson knew that our world
was getti
ng dirty and that many of our plants and animals were dying. He wondered why most people
weren"t trying to solve these problems. He talked to other lawmakers and to the President. They decided
that the President would go around the country and tell people about these problems. He did, but still not
enough people were working on it.
Then in 1969, Senator Nelson had another idea. He decided to have a special day to teach everyone
about the things that needed changing in our environment. He wrote letters to all of the colleges and put a
special article in Scholastic Magazine to tell them about the special day he had planned.
On April 22,1970, the first Earth Day meeting was held. People all over the country made promises to
help improve the environment. Since then, Earth Day has spread all over the planet. People all over the
world know that there are problems we need to work on and this is our special day to look at the planet
and see what needs changing. Isn"t it great? One person had an idea and kept working until everyone
began working together to solve it.
