Today there are many fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy£¨Ë𺦣©huge areas of forests and burn hundreds of homes.

Many experts believe there are several reasons for this sudden increase in fires. The first reason is climate£¨Æøºò£©change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes£¨·¢ÉúÀ׵磩£¬dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn¡¯t allow the grass and trees to burn. As a result, today many forests have thicker vegetation£¨Ö²±»£©.Thicker vegetation means more fuel£¨È¼ÁÏ£©for fires. Also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of a healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of£¨È¥³ý£©dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat£¨Íþв£©to people, firefighters may let it burn naturally.

Do you want to control equipments with your mind? Do you want to power your home with the energy of your own activities? These are two of the developments that engineers at International Business Machines Company (IBM) think will come true within the next five years. The technology company has announced its latest ¡°5 in 5¡± report.

The engineers at IBM think people will soon be able to control many electronic equipments simply by using their minds. They say people will soon have a way to just think about calling or emailing someone in order to make it happen.

Another thing that will happen is a way for people to power their homes and offices using energy from activities like walking or running. Bemie Meyerson, IBM¡¯S President, says this is known as micro-electronic times.

Also, passwords could soon become a thing of the past. IBM says technology developments could soon make passwords unnecessary. Some of the most common ways used to tell people are fingerprints, face and voice differences, and iris scans. The iris is the colored part of the eye. Bemie Meyerson says this technology will soon be more widely used by money machines and other designs.

The fourth possibility on IBM¡¯s ¡°5 in 5¡± list is an end to the digital designs ¡°between those who have technology and those who do not¡±.

1.According to Paragraph 2, you can control an electronic equipments by .

A. writing an English email to it B. giving it a telephone call

C. thinking about your thoughts D. ordering it in your voice

2.We know if micro-electronic times come true, people .

A. will need to run in the house all day

B. will live a much more relaxing life

C. will no longer need to go to their offices

D. can produce electricity through activities

3.If you use iris scans to tell a person, you .

A. have to use passwords at first

B. should show your fingerprints

C. need to look straight at the machine

D. ought to speak to the machine aloud

4.What does the underlined word ¡°password¡± in Paragraph 4 mean?

A. Ö¸ÎÆ B. ÃÜÂë C. Éù¿Ø D. ÅÄÕÕ

5.What will most probably be talked about next after reading the passage?

A. Inventions created by IBM in the past.

B. People¡¯s opinions on the developments.

C. Something that will happen in the future.

D. More information on the fourth possibility.
