Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

¡¾1¡¿ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. Still others keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person¡¯s health than expressing it. They said that when a person is angry, the brain releases hormones (ºÉ¶ûÃÉ) which speed the heart rate, raise blood pressure, or sugar into the blood, etc. ¡¾2¡¿

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.

__¡¾3¡¿__ They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, ¡°¡¾4¡¿ Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.¡±

Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. ¡¾5¡¿

A. In general the person feels excited and ready to act.

B. They said that laughter is much healthier than anger.

C. Expressing anger violently is more harmful than repressing it.

D. Anger may cause you a cancer.

E. Do not express your anger while angr feel from time to time.

G. Doctors say the solution is learning how to deal with anger.

¡¾ÌâÄ¿¡¿ It¡¯s great fun to explore new places¡ªit feels like an adventure£¬even when you know you¡¯re not the first to have been there. But make sure not to get lost or waste time going round in circles.

¡ñ Do the map reading if you¡¯re being driven somewhere. It¡¯ll be easier if you keep turning the map so it follows the direction you¡¯re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn or you¡¯ll have to move to the back seat.

¡ñ Get a group of friends together and go exploring. You'll need a good map, a compass , a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies . Tell someone where you¡¯re going before you set out and let them know what time you expect to be back. The test is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

¡ñ See if your school or a club organizes orienteering activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc.)in the fastest time, or simply as a spare-time activity. Either way, its not only good fun, but a great way to keep fit.

¡¾1¡¿ Sitting beside the driver, you should___________.

A. look ahead to see where there¡¯s a turn

B. direct the driver when necessary

C. move to the back seat if feeling uncomfortable

D. keep looking at the map to find a place to go to

¡¾2¡¿Why do you need to tell someone your exploration plan before setting out?

A. To be saved in case of an accident.

B. To get information when in danger.

C. To share the fun with him/her in exploration.

D. To tell him/her what¡¯s going on with the group members.

¡¾3¡¿Orienteering activities can______________.

A. make people work fast

B. help people organize other activities

C. help people stay healthy

D. make people get prepared for sports

¡¾4¡¿The text mainly talks about____________.

A. the fun of exploration

B. what to bring for exploration

C. the way to use a map in exploration

D. how to prevent getting lost in exploration

¡¾ÌâÄ¿¡¿The oldest and most common source of renewable energy known to man, biomass£¨ÉúÎïÖÊ£© is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere ¡ª- from trees and grasses to agricultural and city ¡ª- life wastes ¡ª-biomass promises to play a continuing role in providing power and heat for millions of people around the world.

According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide(¶þÑõ»¯Ì¼), because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun¡¯s energy. In this way, biomass serves as a sort of natural battery(µç³Ø) for storing the sun¡¯s energy. As long as biomass is produced continuously ¡ª-with only as much grown as is used¡ª the ¡°battery¡± lasts forever.

According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation¡¯s total electricity supply. In 2008¡ª-although the numbers aren¡¯t all in yet¡ª-wind power probably took over first place because of the rapid development of wind farms across the country.

Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner¡¯s money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it.

¡¾1¡¿ Why is biomass considered as ¡° a sort of natural battery¡±?

A. It burns merely plant matter.

B. It keeps producing electricity.

C. It stores the energy from the sun.

D. It produces zero carbon dioxide

¡¾2¡¿ We learn from the text that in 2008 ______.

A. Wind power would be the leader of renewable energy.

B. there was a rapid growth of electricity production

C. biomass might become the main energy source

D. 0.5~0.9 of power supply came from biomass

¡¾3¡¿ Why does the author encourage power plants to use biomass?

A. To prevent the waste of energy.

B. To increase production safety.

C. To reduce pollution.

D. To save money.

¡¾4¡¿ Where does the text probably come from?

A. A research plan. B. A science magazine

C. A book review. D. A business report.
