Tiny microbes (微生物) are at the heart of a new agricultural technique to manage harmful greenhouse gas emissions. Scientists have discovered that microbes can be used to turn carbon dioxide into soil enriching limestone(石灰岩) with the help of a type of tree that grows in tropical areas, such as West Africa.
Researchers have found that when the iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(真菌) and other bacteria, not only does the tree grow well, it also produces mineral limestone in the soil around its roots.
The iroko tree makes a mineral by combining calcium from the earth with carbon dioxide from the atmosphere. Bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon dioxide into the soil, keeping it out of the atmosphere. In addition to storing carbon dioxide in the trees' leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.
The discovery could lead to reforestation projects in tropical countries, and help reduce carbon dioxide emissions in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.
The findings were made in a three year project involving researchers from the University of Edinburgh, Lausanne, Granada and Delft University of Technology.
The project examined several microbiological methods for locking carbon dioxide as limestone, and the iroko bacteria way showed the best results. Work was funded by the European Commission under the Future & Emerging Technologies (FET) scheme.
Dr Bryne Ngwenya of the University of Edinburgh's School of Geosciences, who led the research, said, “By taking advantage of this natural limestone producing process, we have a low tech, safe and easily operating way to lock carbon dioxide out of the atmosphere, while improving farming conditions in tropical countries.”

In New Jersey, there's a row of houses with a green lawn (草坪) that kids can't enjoy. “It's really frustrating. These lawns are useless to me，” Alice, a suburban mom in New Jersey said. She lives in a beautiful community full of green lawns.
It's the middle of summer, but there are no dandelions (蒲公英) in sight. And that's the problem: the lawns are so green because they're full of pesticides(杀虫剂). Warning signs urge parents to keep kids off the chemical laden grass.
Alice says that most lawns and parks in her area are like this. There are plenty of them, but her kids can't play in them. “I just want to let my baby experience the grass，” she said. “Also, I'm sure it's not good for animals. The other day, a woman found a dead deer in her backyard.”
In the 1940s, people often mixed clover (三叶草) with grass to keep lawns strong, which benefited the environment. But over the last few decades, pesticides have taken over. In 2012, the world spent $56 billion on pesticides. They go into farms, lawns, parks and just about anywhere where humans grow plants. These chemicals keep parks' grass and flowers perfect. They just make them useless as actual parks.
That may be more than just annoying. New research has shown that play is good for kids. It helps them discover the world and learn how to get along with other people. But it's hard to get enough play in when there are so few public spaces where kids can play. And the few that exist are often covered in chemicals that make parents uncomfortable.
There are things to take the place of pesticides, like planting a lawn full of clover. Besides, maybe a dandelion here or there isn't the worst thing.
6．Why do parents ask their kids to keep off the grass
A．To shelter kids from damage.
B．To protect the environment.
C．To let kids avoid seeing the dead deer.
D．To let kids have more time to study.
7．What can we infer from Paragraph 4
A．Clover has been popular all the time.
B．The world focuses on building parks.
C．Chemicals help crops grow well in the parks.
D．Nowadays parks aren't what they used to be.
8．New research on kids in Paragraph 5 is mentioned to ________.
A．show play is kids' nature
B．advise planting more clover
C．present chemicals' bad effects on kids
D．encourage kids to get on well with others
C
There was one thought that air pollution affected only the area immediately around large cities with factories and heavy traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is really worldwide.
On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in distant areas away from any industrial cities. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”—keeping heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth's temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen. Perhaps, if we are lucky enough, the two tendencies will offset each other and the world's temperature will stay about the same as it is now. Driven by economic profits, people ignore the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile
9．People used to think that air pollution ________．
A.caused widespread damage in the countryside
B.affected the entire eastern half of the United States
C．had a very bad effect on health
D．existed merely in urban and industrial areas
10．As to the greenhouse effect, the author ________．
A．shares the same view with the scientists
B．is uncertain of its occurrence
C．rejects it as being ungrounded
D．thinks that it will destroy the world soon
11．The underlined word “offset” in the third paragraph could be replaced by “ ________ ”．
A.counteract B．break from
C．get along D．communicate
12．If the world's temperature lowered just a few degrees ________．
A．it would not do much harm to life on earth
B．it would lead major farming areas to disaster
C．particular things would increase greatly in the atmosphere
D．seas and oceans would flood many cities

Born blind is tough in any case. But things were even harder for Srikanth Bolla who was born in a small village in India, where the common belief was that kids with disabilities were “of no use” and therefore, better off dead. Fortunately, Srikanth's parents loved their son and refused to give him up. Instead, they encouraged the blind boy to dream big and reach for the star.
Srikanth did not disappoint his parents. The now twenty four year old man is the founder CEO of Bollant Industries.
Of course, getting here was not easy. Being both blind and poor meant that Srikanth had to face hard challenges. As a young boy, Srikanth attended a regular school near his home. Unfortunately, the students and teachers didn't quite like him because of his disability. As a result, the young boy was largely ignored and often spent the entire day alone.
Concerned this would hold back Srikanth's development, his family decided to send him to a special school in Hyderabad. Sure enough, the young boy soon rose to the top of his class, earning awards in speech and debate competitions. But Srikanth was prevented from studying sciences when he reached 10th grade, because it was thought too “dangerous” for a blind student. Not wanting to give up, Srikanth took legal action and became the first blind student in the country allowed to study sciences.
Later, after graduating from the Massachusetts Institute of Technology, Srikanth set up Bollant Industries in 2012. For just four years, it has become a powerhouse with over 450 employees, 70% of whom are physically challenged.
Being disabled doesn't mean being unable. “If the world looks at me and says, ‘Srikanth, you can do nothing，’ I will look back at the world and say I can do anything，” says the young man.
1．Why was Srikanth sent to a special school
A．His parents became richer than before.
B．He could be treated equally there.
C．This school was free for disabled students.
D．He was sent away by the regular school.
2．What can we know about Srikanth from the text
A．He was born in a poor village.
B．He cared about disabled people.
C．His parents were strict with him in his study.
D．He was loved by the villagers when he was young.
3．What words can best describe Srikanth
A．Intelligent and determined.
B．Active and honest.
C．Patient and careful.
D．Kind but stubborn.
4．What can be the best title for the text
A．Chances Are Everywhere
B．No Challenges, No Success
C．Big Dream Makes a Difference
D．Disability Doesn't Mean Being Unable
B
I strongly believe that if a child is raised with approval, he will learn to love himself and will be successful in his own way. Several weeks ago, I was helping my son in the third grade with his homework and he kept standing up from his chair to go over the math exercises. I kept asking him to sit down, telling him that he would concentrate better. He sat but seconds later, as if he didn't even notice he was doing it, he got up again. I was getting discouraged, but then it hit me. I started noticing his answers were much quicker and more precise when he stood up. Could he be more focused while standing up
This made me start questioning myself and what I had been raised to believe. I was raised to believe that being a quiet, calm child was a sure way to success. This child would have the discipline to study hard, get good grades and become someone important in life.
Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality, and that all they can do is loving and accepting them. As parents, throughout their growing years and beyond that, we need to be our kids' best cheerleaders, guiding them and helping them find their way.
I have stopped asking my son to sit down and concentrate. Obviously, he is concentrating just in his own way and not mine. We need to learn to accept our kids' ways of doing things. Some way may have worked for us but it doesn't mean we need to carry it through generations. There is nothing sweeter than being individual and unique. It makes us free and happy and that's just the way I want my kids to live their own life.

Leon, 12, was born without fingers on his left hand. That didn't stop him from being able to do many tasks. But Leon could not grasp more than one object at a time. So Leon's father, Paul, created a prosthesis(义肢), using a 3 D printer. Now Leon has fingers that can open and close. “It was a do it yourself, father and son adventure，” says Paul.
When Leon was a baby, his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. “The doctor said Leon should first learn to get full use of the hand he was born with，” says Paul. As Leon got older, his father considered buying a prosthetic hand, which can cost as much as $30, 000. Then Paul found a more affordable solution.
One day, Paul discovered a video on the Internet about Robohand, a prosthesis created by a 3 D printer. He downloaded the free instructions and called Robohand's creators for advice. They told him all he needed was a 3 D printer—which costs around $2，000 and some materials.
Luckily, Leon's school had recently bought a 3 D printer and it offered to help Paul build the hand for Leon. “We used a soccer shin pad (护胫) , cardboard, and tape. They cost about $10，” says Paul.
With his new hand, Leon can do things better. “I can help my mom more, because now I can carry two grocery bags，” he says.
Leon's father has already built several hands for Leon. Leon helps design each one. He says there's one thing in particular that he wants to do with a future prosthesis. “The goal，” he tells the reporter from the local evening paper, “is to be able to tie my shoelaces (鞋带)”．
1．Why did Leon's doctor disapprove of his using a prosthesis in his childhood
A．The original hand could do many tasks.
B．A prosthesis was very expensive at that time.
C．To learn to use the disabled hand was important.

When Allen invited me to a camping trip to the mountains, I imagined us in a cosy cabin overlooking a lake, with a warm fireplace, hot cocoa and soft beds. But my happy imagination became a nightmare when Allen and his older brother, Leo, showed up with a truck filled with camping equipment—tents, sleeping bags and water bottles. We were going on survival training!
The ever efficient Leo was keen to leave the city behind us and urged us to hurry. Several hours later, as we drove through the forest, the mountains seemed bigger than I remembered; the trees were larger, and the environment felt more threatening.
At the trailhead, Leo tied a sleeping bag onto my already heavy pack and lectured Allen and me about hiking rules. Then, with Leo in the lead, we set off along the narrow and steep dirt track that wound up the mountain.
After 6 hours of climbing, we finally reached the top. My legs aching, I dropped my pack and groaned (呻吟) but there was no time to rest. “We need to set up camp quickly，” said Leo. “There are dark clouds coming in. A storm is on its way.”
I thought he was kidding, but Leo was quite serious. He and Allen worked expertly, while I stood around and pretended to help, thunder rumbling in the distance. We just finished putting up the tent when it hit. The wind, thunder, and lightning were relentless.
Leo, sensing that I was scared, started telling us some stories about his camping adventures. But each time lightning lit up the tent and the thunder echoed, I jumped. “Don't worry. Summer storms pass quickly，” said Leo, trying to comfort me. “And at least the rain will keep the bears away，” he said with a teasing smile, which was less comforting.
And just as quickly as the storm came rushing in, it passed, and we exited the tent. The view was incredible—I could see for miles. As darkness set in, I stared in wonder at the millions of glowing stars in the night sky.
I won't lie—I was still wishing for a hot shower and a soft bed, but as I gazed upward at the Milky Way, I knew this was an adventure I would never forget.
5．Why was the author surprised when Allen came to get him at the beginning of the story
A．Allen had arrived earlier than arranged.

C．He realized their trip would be challenging.
D．Allen's brother was unexpectedly with him.
6．Why was it necessary to set up camp immediately after reaching the mountain top
A．It was almost night time.
B．The weather was changing.
C．They were tired and needed to rest.
D．They needed protection from animals.
7．What can we guess about Leo
A．He was an experienced and capable hiker.
B．He was inconsiderate of others' feelings.
C．He had known the writer for a long time.
D．He had not been to this mountain before.
8．How did the author feel at the end of the story

阅读理解
A
Once upon a time, a daughter complained to her father that her life was unhappy and that she was tired of struggling all the time.
Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire. Once the three pots began to boil, he placed potatoes, eggs and coffee beans in them. After 20 minutes, he took them out, putting the potatoes and eggs in a bowl and the coffee in a cup.
Turning to his daughter, he said, “Look closer, and touch the potatoes.” She did and noted that they were soft. He then asked her to take an egg and break it. After stripping off the shell, she observed the hard boiled egg. Finally, he asked her to taste the coffee. Its good smell brought a smile to her face.
“Father, what does this mean？”she asked. He then explained that the potatoes, the eggs and the coffee beans were in the same adversity—the boiling water. However, each one reacted differently.
The strong and hard potatoes became soft and weak in the boiling water. The eggs were fragile,__ with thin outer shell protecting their liquid until they were put in the boiling water. Then the inside of the eggs became hard. However, the coffee beans were unique. After they were exposed to the boiling water, they changed the water and created something new. “Which one do you want to be like？”he asked. “When adversity knocks on your door, how will you respond？”

At the age of eight, Glenn Cunningham was severely injured in a fire. He had major burns over the lower half of his body and was taken to a nearby county hospital.
From his bed, the semi conscious (半昏迷的) little boy heard the doctor talking to his mother. The doctor told his mother that he would surely die—which was for the best, really—for the terrible fire had destroyed the lower half of his body.
But somehow, to the amazement of the physician, he did survive. The mother was told that her son was bound to spend his lifetime in a wheelchair.
But this brave little boy was determined that he would walk and even run. But unfortunately, from the waist down, Glenn had no motor ability. His thin, scarred legs just hung there, all but lifeless. Yet his courage that he would walk was as strong as ever.
One sunny day his mother wheeled him out into the yard to get some fresh air. This day, instead of sitting there, he threw himself from the chair. Glenn worked his way to the fence, dragging (缓慢移动) his legs behind him. Then, step by step, he began dragging himself along the fence, determined that he would walk. He started to do this every day until eventually he did develop the ability first to stand up, then to walk with help, then to walk by himself—and then amazingly—to run. Glenn began to run to school. He ran everywhere as fast as he could. Later in college, Glenn joined the track team where he received the nickname(绰号) “the Kansas Flyer”．
1938 witnessed this young man's another amazing achievement. This young man, who was not expected to survive, who would surely never walk, and who could never hope to run, ran a mile in 4 minutes and 4.4 seconds, the world's fastest indoor mile! His perseverance paid off.

Jennifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin Eau Claire and became the first in her large family to earn a bachelor's degree.
Mauer, of Edgar, Wisconsin, grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition (学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.
Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves：nursing. She chose the UW Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four year degree close to home. She could drive to class and be home in the evening to help with her kids. Jennifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68 year old mother helped take care of the children at times.
Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲) to achieve her goal, giving up many nights with her kids and missing important events to study. “Some nights my heart was breaking to have to pick between my kids and studying for exams or papers，” she says. However, her children have learned an important lesson witnessing their mother earn her degree. Jennifer is a first generation graduate and an inspiration to her family—and that's pretty powerful.
