If you want your land to keep fertile, you must try to stop soil from being carried away by water or wind. When soil is taken away by flowing water or blowing winds we call it soil erosion. Ways have been found to stop soil erosion, and this is known as soil conservation. One way of stopping soil erosion is to grow small plants such as grass. These plants are referred to a cover crops, whose roots hold the soil tightly together. The rain water can not wash away the soil. When trees and tall bushes are planted at the edges of an open field, soil erosion by strong winds can not take place. The trees and bushes, which act as a very big and firm wall, protect the open land from the winds. The way to stoop soil erosion on slopes is to build terraces on the slope of hillside and mountainside. When the slope of a hillside is cut into “step”, water carrying soil can not run straight down the terraces, which are used to slow down the speed of the flowing water containing much soil in it. In this way most of the soil in the water is left behind on the terraces, much soil in it.

A.because their roots hold soil tightly
B.to stop soil from being blown away by winds.

第二部分:閱讀理解(共20小題,每小題2分,滿分40分)
第一節(jié):閱讀下列短文,然后從所給的四個選項 (A、B、C和D) 中選出最佳選項,并寫在答題紙上.
Every spring scores of people flock to the Buzzard Festival(禿鷲節(jié)) at Hinckley, Ohio. They come to watch for buzzards. Most would be glad just to take a look at a buzzard. If they do see one of these “flying garbage cans”, it will probably be circling high in the sky. From there it can watch the ground for signs of the waste and the dead animals on which it feeds.
The buzzard is the ugliest bird in the United States. In fact, it may well be the ugliest bird in the world. It has a small, bare, pink head. Its thick body is covered with dark, rough feathers.
In spite of its looks, the buzzard is important to the people of Hinckley. It is their first sign of spring. After a winter in the south, buzzards return to their homes in the north. In the Hinckley area, they always return on March 15. No one knows why. But they have come back to Hinckley Ridge on that day, sure as clocks work, for at least forty years.
The excitement starts in February. By the middle of March it has reached a high peak. Bets are placed. Prizes go to the person who sees the first buzzard. Radio stations and newspapers tell of the coming festival. And on the weekend after March 15 the people of Hinckley hold their Buzzard Festival.
The people come and look around. They chat. They eat their pancakes and sausages. Then they drive past Buzzard’s Roost on Hinckley Ridge.
A lot of them stop near the road at the stand set up to give information to visitors. There they can hear, from a recording, the main facts about the buzzard. They can see a stuffed buzzard. They can look at some pictures taken of buzzards in other years. With good luck and a strong pair of field glasses, they may sight one or two live buzzards high in the sky.
Buzzards may be ugly. They may be “flying garbage cans”. But in Hinckley they are just as welcome as the swallows are in Capistrano in California. It would be a sad spring indeed if the buzzards ever failed to come back to Hinckley Ridge.
61.A good title for this story would be _________.
A. The Hinckley Buzzard Festival             
B. Buzzard, the Ugliest Bird
C. Why the Buzzard Has a Pink Head          
D. The Return of “The Garbage Can”
62.The buzzard is called the“flying garbage can”because it _________.
A. is ugly                                  
B. eats waste and dead animals
C. looks like a garbage can                    
D. collect rubbish on the ground
63.The surprising thing about Hinckley’s buzzards is that _________.
A. they spend the winter in the south
B. they come very close to the town
C. they return on the same day each year
D. both buzzards and swallows return to Capistrano on March 15
64.At the information stand, visitors to Hinckley’s Buzzard Festival can _________.
A. feed their pancakes and sausages to buzzards
B. easily see a live buzzard
C. take some pictures with the background of live buzzards
D. learn some facts about the buzzard

Determined to make school more related to the workplace, Roosevelt High School in Portland, Oregon, developed a school-to-work program. In their first year, students are offered some job pathways in natural resources, human services, health care, business, arts and communication. The following year, each student chooses one of the pathways and examines it in depth, spending three hours a week watching someone on the job. Such a program is also in practice in some other states.
The school-to-work program is built around a partnership(伙伴關系). For example, Eastman Kodak, a major employer(雇主) in Colorado, introduces students to business by helping them construct(建設) a model city using small pieces of wood. “The children use the models to decide on the best place to set up schools,” says Lucille Mantelli , director for Eastman Kodak in Colorado.  Kodak introduces math by teaching fifth graders to use their pocket money properly.  They also provide one-on-one job watching experiences and offer chances of practice for high school juniors and seniors. “Students come to the workplace two or three hours a week,” explains Mantelli. “They do the job for us. We pay them and they get school credits (學分). We also give them our views on their performance and developmental opportunities.”
In these partnerships, everybody wins. The students tend to(傾向于) take more difficult courses than students in schools that don’t offer such programs. Business benefits(獲益) by having a better prepared workforce needed in future years. “It’s a way for us to work with the school systems to develop the type of workforce we’ll need in future years,” Mantelli continued. “We need employees who understand the basics of reading and writing. We need them to be good at math and to be comfortable working on a team.”
“Our theory is that they can learn as much outside the classroom as in. All students have the ability to change the world, not just to live in it. To do that, they have to know how to solve problems and use critical(批判的)thinking skills. We need to encourage them to dream about jobs that go beyond what they see today,”  concludes(得出結論) a school-to-work program organizer.
58. Using the example of Eastman Kodak in Colorado, the writer shows us ____.
A. what the school decides to do 
B. why the students get paid for their jobs 
C. where the students have their math class 
D. what role the business plays in the program
59. The main purpose of the school-to-work program is to _____.
A. offer students more difficult courses             
B. introduce new job opportunities to schools
C. improve relations between students and teachers 
D. make what students learn in school related to the workplace
60. According to the text, Lucille Mantelli is ____.
A. a math teacher                 B. a school designer      
C. a company manager          D. a program organizer
61. What does the writer mean by saying “…everybody wins.” (Paragraph 3)?
A. Students get school credits by taking examinations.
B. Both students and business benefit from the program.                  
C. The working conditions of the company have improved greatly.
D. Every teacher and student gets paid for working outside the school.

Making group purchases of famous local products and cosmetics (化妝品) with co-workers has become a common habit for the nine-to-fivers. But if your impression of group buys is still a piece of paper being passed around the office, everyone writes their details down, or endless phone calls or faxes to the supplier, then I’m sorry to say you’re behind the times. The popular way to make such purchases today is to get on line, form a special “group” and shop together. Not only can you save money by getting the best discounts, but it’s also a great way to meet new people.
“You could cut off my clicking finger and I’d still keep shopping this way!” so goes a common comment left by customers of China’s famous e-commerce website “Taobao”. Some even refer to group purchasing as a “path of no return”, saying that “Once you’ve tried it, you’ll get hooked!”
The origins of this new trend can be found in China’s well-known online consumers’ BBS, 55BBS, and the shopping boards. Since most BBS users are “white-collared workers and students who live in concentrated areas, buying clothes, food, and so on as a group saves on delivery costs as well as – if they meet the seller’s criteria (標準) – earn gifts, discounts, and frequent shopper points.
Users of this online group shopping boards purchase a lot of different items, from Japanese and Korean style clothes and Ugg boots, through fake eyelashes (假睫毛), stockings, food seasonings (調味品), and kitchen knives, to cosmetic masks and online college courses. All kinds of things have people coming together in groups to buy them, and the pickups are often organized on college campuses or office buildings.
Internet observer Liu Chenxi points the purchasing behavior that these online groups’ power creates a “team” effect. Unlike e-commerce sites driven by individuals’ purchases, sites that create this team effect have users that come together to achieve a common goal. The Internet has made this joining of forces to form group buying power possible, and it continues to snowball all around us.
68. The passage mainly deals with _________.
A. group purchases with co-workers    
B. online group purchases
C. how to do shopping online             
D. buying famous local products and cosmetics
69. What does the word “hooked” in Paragraph 2 probably mean?
A. excited               B. lost                   C. addicted           D. bored
70. According to the text, this kind of purchase has some benefits EXCEPT________.
A. earning gifts                                         B. making new friends
C. saving money                                D. saving time
71. What can we infer from the text?。
A. Online group shopping will become more and more popular.
B. The goods are usually delivered to each doorstep.
C. Doing shopping online is not reliable.
D. People prefer to do group purchases with their co-workers.

Compared to adults, children seem to be moving constantly.So it's no surprise that most parents who are quizzed about their child's physical activity level describe their children as fairly active.But a new study of nearly 2,000 British school children suggests that many parents overestimate the amount of physical activity their children are really getting.
The researchers equipped 1,892 British school children, ages 9 and 10, with accelerometers that measure all physical activity during a given time period.The research, known as the Speedy study collected the exercise data from children at 92 schools in Norfolk, England, between April and July 2007.
A child was regarded inactive if he or she recorded less than an hour a day of physical activity.Although the majority of children studied were getting enough physical activity, a sizable minority of children were not.Overall, 39 percent of girls and 18 percent of boys studied were getting less than an hour of physical activity each day.
But if you asked the parents of the inactive children to describe their child's activity level, the vast majority—80 percent—described their children as fairly or very physically active, according to the findings published in the American Journal of Preventive Medicine.Interestingly, the children themselves had more awareness about their lack of physical activity.Overall, 40 percent of children overestimated their physical activity.
But it wasn't the parents of overweight children who were most likely to guess wrong about physical activity levels.The parents who were most out of touch about their child's physical fitness were more likely to have children who were slim.Parents of girls were also more likely to overestimate physical activity.The researchers noted that parents should be educated about the importance of physical activity for children even if the child is not overweight.
"Parents of slim children appear to assume that their children are adequately active," the study authors reported."Increasing awareness regarding health benefits of physical activity beyond weight control might help have a correct idea of physical activity levels and encourage behavior change."
69.According to the Speedy study, what kind of children can be judged physically inactive?
A.Slim children.
B.Children with less than an hour a day of physical activity.
C.Overweight children.
D.Children out of touch with their parents for a long time.
70.What does the writer probably mean by saying "a sizable minority of children were not" in Paragraph 3?
A.The amount of children's physical activity is far from the writer's satisfaction.
B.Only a small number of children were not getting enough physical activity.
C.A small number of children didn't overestimate their physical activity.
D.The minority of children were not studied at all.
71.The passage is intended to ____.
A.encourage parents to fairly judge their child's physical activity levels
B.persuade parents to keep an eye on their children's weight
C.urge children to wear accelerometers during exercise
D.advise parents to keep in touch with their children

   CHICAGO ---Call it a reward, or just “bribery(賄賂)”.
Whichever it is, many parents today readily admit to buying off their children, who get goodies(好東西) for anything from behaving in a restaurant to sleeping all night in their own beds.
That’s what worries parenting experts.
“I think that reward systems have a time and a place and work really well in certain situations,” says Marcy Safyer, director of the Adelphi University Institute for Parenting.
“But what often gets lost for people is being able to figure out how to communicate to their kids that doing the thing is rewarding enough,” Safyer says.
Parents and experts alike agree that the dynamic(動力) is partly a reflection of the world we live in. It’s unrealistic to think a parent wouldn’t reward their children with material things sometimes, says Robin Lanzi, a clinical psychologist and mother of four who’s the research director at the Center on Health and Education at Georgetown University.
“But you want to make sure that they match the behavior, so it’s not something huge for something small,” Lanzi says.
She recalls hearing about a father who offered his child a Nintendo Wii game system for scoring a couple goals in a soccer game.
Elizabeth Powell, a mother of two young daughters in Austin, Texas, knows what she means.
“You want to raise them in a way that they’re respectful and appreciate things,” Powell says of her children. “But sometimes, you wonder now if kids appreciate even a new pair of shoes. ”
小題1:Parenting experts are worried that ____ .
A.today’s children are fed up with material things
B.parents are rewarding their kids improperly
C.today’s children are more and more demanding(苛求的)
D.there is lack of communication between parents and children
小題2:What Safyer says suggests that ____ .
A.reward systems are quite limited in developing abilities
B.reward systems work well regardless of(不管) time and place
C.reward systems are still not made full use of to develop abilities
D.reward systems are often used at the wrong time and place
小題3:What can we learn from what Robin Lanzi says?
A.She holds a different opinion from other parenting experts.
B.She thinks children can’t behave well without being rewarded.
C.She holds a similar belief to Safyer and gives further explanation.
D.She doesn’t believe in rewarding children for good behavior.
小題4:The father who offered his child a Nintendo Wii game system can be regarded as
_____.
A.over-rewarding his child
B.giving his child proper reward
C.respecting and appreciating his child
D.giving something small for something huge
