Across countryside, non-food crops are growing alongside wheat．Some are used in new alternatives to plastics and other materials, but others will simply be burned．
Burning crops is becoming more popular because it is good for the planet．Doing so is also cheaper than burning fossil fuels．As more land is devoted to non-food crop production, the economics of crops for fuel are likely to become even more favorable．
Humans have been burning such biomass—organic materials from plants or animals— since they discovered fire．But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion．
Even allowing for emissions (排放) of carbon dioxide from fuel used in planting, harvesting, processing and transporting biomass fuel, replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90 percent．
Power stations around the world are experimenting with forms of biomass to add to their coal or oil, with encouraging results．Indeed, power companies could profit by turning to biomass, especially when the subsidies (补助) many governments offer for using renewable energy are taken into account．
Farmers can benefit from growing biomass．In Europe, the reduction of subsidies for certain crops is exposing farmers to market forces．Instead of being paid for whatever they produce, farmers must seek a clear demand for their product．Many believe that the demand for alternatives to fossil fuels could be just such a driver．
But while biomass offers a variety of potential alternatives, the world's infrastructure (基础设施） has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted．
Also, there are problems with using biomass．Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment, few are built to run on biomass alone．Burning some forms of biomass also causes environmental problems．Oils and waste can be smelly, while wood produces smoke unless burned properly．
The supply chains for fossil fuels are set up well, but those for biomass are just the beginning. Sources of supply for biomass rely on farm production and can therefore be less reliable. They are necessarily limited and it wouldn't make sense to turn a very large amount of valuable agricultural land away from food crops．But as the world adjusts to the need to control greenhouse gas emissions, these problems may receive more attention．
1.What do we know about biomass?
A．It is a useful way of burning crops．
B．It is plant and animal matter used to provide power．
C．It is a new alternative to be used widely．
D．It is a popular approach to fighting against pollution．
2.What are the advantages of using biomass?
a．It gives off less greenhouse gases．

3.For coal-fired power stations, ______．
A．more effective ways to use biomass have been tried
B．using renewable energy has become their daily task
C．burning biomass alone would require considerable changes

1.B
2.D
3.C
4.D

No one else knew about the extra club in Zach Nash’s golf bag. It belonged to a friend, and Zach forgot it was there as he played his way to victory in a junior tournament（锦标赛）last summer in Wisconsin, US.
The 14-year-old accepted his medal, celebrated with his grandparents who had come from a long way to watch. But when he stopped by his country club to share the news, a professional player noticed something wrong. “Count your clubs,” he told the teenager.
Fifteen—one more than allowed. Zach’s eyes filled with tears.
If Zach had just won a basketball championship or a soccer game and someone had discovered a violation after the win, it would not have mattered. It is nothing unusual for a soccer player to dive to the turf to draw fouls（假摔以使对方犯规）.
Golf is different. In a win-at-all-costs world, the game holds itself to a higher standard. Golf isn’t a game where referees watch closely. In golf tournaments, dozens of competitors are spread across acres of land, so officials cannot hope to see each shot. Competitors call penalties（处罚）on themselves.
“It was a sport for gentlemen, and gentlemen did not care about winning. They care about doing the right thing,” said Robert Simon, a golf coach at Hamilton College in New York.
Honesty became a medal of honor. When one of the game’s early stars, Bobby Jones, was p
raised for calling a penalty on himself at the 1925 US Open, he replied: “You might as well praise a man for not robbing a bank.”
So even the error had no effect on Zach’s final score—he has never used the extra club, the teenager packed up his medal and dropped it in the mail. “But this is golf, and rules are rules. I just knew what I had to do,” he said.
Then came another tournament. Before teeing off(开球), Zach counted his clubs—four times.
【小题1】What can we infer from the text?
| A．A friend put an extra club in Zach’s bag. |
| B．Zach returned the medal that he had won. |
| C．Zach’s grandparents encouraged him to play fair. |
| D．Zach regretted meeting with the professional player. |
| A．honor comes before victory |
| B．players are superior to coaches |
| C．referees have to watch each shot |
| D．players needn't care about medals |
om the underlined sentence?| A．One should be praised for not robbing a bank. |
| B．Bobby looked down upon bank robbers. |
| C．Little did Bobby care about the penalty. |
| D．Observing rules demands no praise. |
| A．He remembered the lesson. | B．He lacked self-confidence. |
| C．He felt a little too nervous. | |
| D．He was no good with numbers. |

Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback. Simply speaking, it means the longer kids are out of school, the more they forget. The only thing they might gain is weight.
Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.
But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, "Year-round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year."
Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.
But calling them "summer school" could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like "summer camp," "enrichment," "extra time" and "hands-on learning."

| A．helps children to gain weight |

| B．have much less time for relaxation every year |
| C．have generally the same number of class days |

| D．Nothing can help the students who fall behind after the vocation. |

I used to watch her from my kitchen window. She seemed so small as she muscled her way through the crowd of boys on the playground. The school was across the street from our home and I would often watch the kids as they played during break. I remember the first day I saw her playing basketball. I watched in wonder as she ran circles around the other kids. She managed to shoot jump shots just over their heads and into the net. The boys always tried to stop her but no one could. I began to notice her at other times, basketball in hand, playing alone.
One day I asked her why she practiced so much. Without a moment of hesitation she said, “I want to go to college. The only way I can go is to get a scholarship. I am going to play college basketball. I want to be the best. My Daddy told me if the dream is big enough, the facts don’t count.” Well, I had to give it to her—she was determined.

We often hear the phrase:“You’ve a greater chance of being struck by lightning.” It is used to describe something that hasn’t got much chance of happening. However, the common saying undermines(掩盖) the very real dangers of lightning. Last Friday, at least 5 people were killed by lightning in Nepal. Lightning strikes are the second most common cause of deaths during natural disasters in the US. The first is floods. Around 400 people nationwide are struck by lightning each year, and of those73 people die. That means more people are killed by lightning than by tornadoes and hurricanes. Because lightning kills only one or two people at a time, its danger does not receive as much attention as other disasters.
So to raise awareness, the US has made June 22 to 28 National Lightning Safety Week. It aims to warn the public of the dangers of lightning and provide safety tips during thunderstorms. “If you hear thunder , you are in danger from lightning,” said Rocky Lopes, a disaster educator at the American Red Cross.“Thunder means that lightning is close enough to hit you at any minute, so you should move indoors immediately and stay there until after the storm has ended. The single most important thing to remember is to seek hiding place,”Lopes said.
Summer is the high time for lightning storms, so when lightning strikes across the sky, remember these safety tips:
Stop working, fishing, swimming or playing in open fields.
If you can count less than ten seconds between a thunder and a lightning flash, take cover inside the nearest building.
Do not stand under a tree.
Get off bicycles or motorcycles.
Crouch down(蹲下)if there is no hiding place.
Avoid open spaces, wire fences, metal objects and electrical objects such as hair driers.
1.The popular opinion about being struck by lightening is that .
A. there is a greater chance for being killed by lightening than any other natural disaster
B. it is the most dangerous among all the natural disasters
C. the chance for a person to be struck by lightening is very small
D. it is impossible for people to be killed by lightening
2. The average death rate of being struck by lightening in US is about .
A.18% B.50% C.30% D.73%
3. Among all the safety tips, the most important one is that when you hear thunder in the open air， .
A. just stand by your bicycles and motorcycles
B. quickly find a place to go inside
C. count ten seconds between a thunder and a lightening
D. don’t have a hair drier in your hand
4. According to the passage, which of the following is TRUE?
A. There are more people killed by tornadoes and hurricanes than by lightening in US each year.
B. There are on average 5 persons killed by lightening in Nepal each day.
C. The death rate of being stuck by lightening is much higher than by other natural disasters.
D. The National Lightening Safety Week is made to warn the public against lightening.
