When I met him,I had a lot of anger inside of me.I’ve lived my whole life in Spanish Harlem,but in my neighborhood,there are shoot-ups all the time.I know kids who have been shot or beaten up.I have friends who ended up in prison.I could have ended up that way,too,but Mr.Clark wouldn’t let that happen.
Mr.Clark worked long hours,making sure I did my work.My grades rose.In fact,the scores of our whole class rose.One day,he took our class to see The Phantom of the Opera,and it was the first time some kids had ever been out of Harlem.Before the show,he treated us to dinner at a restaurant and taught us not to talk with our mouths full.We did not want to let him down.
Mr.Clark was selected as Disney’s 2000 Teacher of the Year.He said he would draw three names out of a hat;those students would go with him to Los Angeles to get the award.But when the time came to draw names,Mr.Clark said,“You’re all going.”
On graduation day,there were a lot of tears.We didn’t want his class to end.In 2001,he moved to Atlanta,but he always kept in touch.He started giving lectures about education,and wrote a bestselling book based on his classroom rules,The Essential 55.In 2003,Mr.Clark took some of us on a trip to South Africa to deliver school supplies and visit orphanages(孤儿院).It was the most amazing experience of my life.It’s now my dream to one day start a group of women’s clubs,helping people from all backgrounds.

A small town in southwest Britain is banning(禁止) plastic bags in an attempt to help the environment and cut waste—a step that environmentalists believe is a first for Europe.
Shopkeepers in Modbury population 1500,agreed to stop handing out disposable plastic bags to customers on Saturday.They said paper sacks and cloth carrier bags would be offered instead.
Last month,San Franciso became the first U.S. city to ban plastic grocery bags.Internationally,laws to discourage the use of plastic bags have been passed in parts of South Africa and Ireland,where governments either tax shoppers who use them or fine companies that hand them out.Bangladesh already bans them,and so do at least 30 remote Alaskan villages.
Modbury,about 225 miles southwest of London,has also declared a bag amnesty(宽限期),allowing local people to hand in plastic bags that have piled up at home.They will be sent for traveling.
The Modbury ban was the idea of Rebecca Hosking,who saw the effect of bags on marine life while working in the Pacific as a wildlife camerawoman.She said response(反应) in the town so far had been “really positive”.
“Modbury is quite an old-fashioned town and a lot of people have wicker baskets to go out shopping anyway,”Hosking told Sky News Television.
The Worldwatch Institute,an environmental research agency,states that 100 billion plastic bags are thrown away each year in the United States alone.More than 500 billion are used yearly around the world.
1.What was Rebecca Hosking?
A.A lawyer. B.An environmentalist.
C.A sailor. D.A photographer.
2.The underlined word “disposable” in the passage probably means _______.
A.acceptable B.valuable
C.throw-away D.long-lasting
3.It can be inferred from the passage that _______.
A.most of the people in Modbury continue to use plastic bags
B.fewer and fewer plastic bags will be used in the world
C.San Francisco is the first city to ban plastic bags in the world
D.most countries in the world have passed laws to ban plastic bags
4.Which of the following would be the best title of the passage?
A.Environmental Protection
B.Big Cities Banning Plastic Bags
C.Effect of Plastic Bags on Sea Animals
D.British Town Banning Plastic Bags

Scientists have found what look like caves on Mars(火星),and say they could be protecting life from the planet’s terrible environment.
Images of the Mars caves from Northern
Arizona University
The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter.Each as large as a football field,they may be openings into natural caves below the Martian surface.
“If there is life on Mars,there is a good chance you’d find it in caves,”said Jut Wynne,one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.
Jonathan Clarke,a geologist with the Mars Society of Australia,yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm,suggesting hot air trapped during the day is flowing out.
“I said:‘Wow,that’s a cave’,”Dr.Clarke said excitedly.“People have been looking for these for a long time;now we have found them.”
He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold,radiation-soaked(充满辐射的),dry surface.
“Tiny drops of water could collect inside,”he said.“If there are gases coming out,they could provide energy for a whole range of bacteria.A cave is also a protection from radiation;the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lava flows(管状岩浆流) spread across the planet long ago.The outside of the tubes cooled,forming solid walls,while something hotter inside allowed the remaining lava to flow out,forming caves.
1.What does the passage mainly talk about?
A.How the caves were formed on Mars.
B.How scientists found these caves on Mars.
C.Caves on Mars may be full of hot air or a sign of life.
D.Scientists have completely recognized the surface of Mars.
2.We can learn from the passage that _______.
A.water has already been found on Mars
B.the scientists found all the caves at night
C.it is certain that there is life in these caves
D.the surface of Mars is bitterly cold,radiation-soaked and dry
3.According to the passage,Dr.Clarke was so excited because _______.
A.such caves could provide energy for life
B.they had finally found the caves on Mars
C.such caves would be perfect places to hunt for life
D.scientists had long been looking for these caves
4.Necessary conditions for life on Mars mentioned in the passage may include _______.
A.lava and energy
B.water and radiation from space
C.gases and lava
D.water and protection from radiation

Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back,a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs,catching their responses to a range of stimuli(刺激物) with video cameras.To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years.The dogs were all family pets whose owners had allowed them to take part in the experiment at Ban University.The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli.They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side.When they were shown an unfamiliar human they wagged to the right,but with somewhat less enthusiasm.The appearance of a cat again caused a right-hand side wag,although with less intensity again.The appearance of a large unfamiliar dog,similar to a German shepherd,changed the direction of tail wagging to the left.Reseachers supposed the dog was thinking of moving back.When the dogs were not shown any stimuli they tended to wag their tails to the left,suggesting they preferred company.While the changes in the tail wagging were not easily noticed without the aid of video,it was thought that the findings could help people judge the mood(心情) of dogs.Computer and video systems,for example,could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
1.The video cameras were used to catch the dogs’ responses because _______.
A.it was easier to catch the dogs’ response changes in the tail wagging
B.the dogs were put in the wooden boxes and tested one at a time
C.they enabled the dogs’ owners to know about their dogs’ habit
D.the dogs wagged their tails in different directions when they were in different moods
2.The underlined word “intensity” in the passage means _______.
A.surprise B.worry
C.excitement D.interest
3.When there are no stimuli,a dog will _______.
A.wag to the left B.wag to the right
C.not wag at all D.wag to the left and then to the right
4.The underlined word “they” refers to _______.
A.the dogs B.the trainers
C.the systems D.the researchers
5.The purpose of doing the experiment is _______.
A.to train dogs for their owners
B.to help people judge the mood of dogs
C.to help dogs find company
D.to help people choose their pet dogs
