The oldest and most common source(來源) of renewable energy known to man, biomass is one of the most important forms of energy production in the United States and elsewhere．Since such a wide variety of biomass materials is everywhere—from trees and grasses to agricultural and city-life wastes—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(二氧化碳), 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(電池) for storing the sun’s energy．As long as biomass is produced continuously —with only as much grown as is used—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—although the numbers aren’t all in yet—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．

1.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．

2.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

3.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．

4.Where does the text probably come from?

A．A research plan．

B．A science magazine

C．A book review．

D．A business report．

Many years ago, when I graduated from school and was working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register (收款臺), I said hello to an older couple who were also paying for gas.

I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.

I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery was dead. Then I noticed that the Friendly Ford dealership－a shop selling cars－was right next door. I walked over and found two salesmen in the showroom.

"Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

"Thank you"－two powerful words. They're easy to say and mean so much.

1.The words "took off" underlined in Paragraph 2 mean "_____".

A. turned off B. moved off

C. put off D. set up

2.What happened when the author found smoke coming out of his car?

A. He had it pulled back to the gas station.

B. The couple sent him a business card.

C. The couple offered to help him.

D. He called his friend for help.

3.The battery of the author's car was dead because _____.

A. he forgot to turn off the lights

B. the meeting lasted a whole day

C. he drove too long a distance

D. something went wrong with the lights

4. By telling his own experiences, the author tries to show _____.

A. how to write a thank-you letter

B. how to deal with car problems

C. the kind-heartedness of other people

D. the importance of expressing thanks

What I saw made me scared. A building in my neighborhood was on fire. Some people were using water to put out the fire; others were rushing towards the building to help put out the fire. The building had three floors. The fire started on the first floor. Soon, it spread (擴散) to the second floor. There were some people on the second floor at that time. Their lives were in danger.

Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new recipe of success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two-thirds of the homes interviewed reported a positive relationship between their cat and dog.

However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals were just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.

In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk ‘dog’ and dogs can learn how to talk ‘Cat’.

What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn how to read each other's body signals, suggesting that the two may have more in common than we previously suspected. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.

The significance of the research on cats and dogs may go beyond pets ─ to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

1.Some cats and dogs may fight when ________.

A. they misunderstood each other's signals

B. they look away from each other

C. they are cold to each other

D. they are introduced at an early age

2.What is found surprising about cats and dogs?

A. They eat and sleep each other.

B. They learn to speak each other's language.

C. They observe each other's behaviors.

D. They know something from each other's voices.

3.It is suggested in Paragraph 4 that cats and dogs ________.

A. have common interests

B. have a common body language

C. are less different than was thought

D. are less intelligent than was expected

4.What can we human beings learn from cats and dogs?

A. We should live in peace with animals.

B. We should know more about animals.

C. We should learn to live in harmony.

D. We should learn more body languages.
