Thirty-five years ago, with just one acre of land, a couple of seeds and a bucket of hope, one Nigerian-born scientist began his mission to defeat famine(饥荒) on his continent.
News of the drought across Africa in the early 1980s troubled Godfery Nzamujo. Equipped with a microbiology PhD and his faith, he travelled back to Africa. There, he found the continent ecologically rich, diverse and capable of producing food. He believes drought wasn't the only reason for widespread hunger, and that unsustainability(不可持续性) had been left out.
Godfery began designing a “zero waste” agriculture system that would not only increase food security, but also help the environment and create jobs. In 1985, he started his sustainable farm “Songhai” in the West African country of Benin.
Godfery lives on the farm and constantly updates his techniques. He credits Songhai's success to his degrees in science and engineering. But he also thanks his spiritual and cultural roots, and his father—a driving force in his life who encouraged him to pursue his studies to the highest degree and to use Songhai to share his knowledge.
Songhai has several “eco-literacy” development programs. They range from 18-month training courses for farmer-enterprisers, to shorter stays to learn techniques like weeding. People come from all over the world to study Godfery's methods.
After seeing the success of his first zero waste farm, he expanded throughout Benin and Western Africa. Today, the Songhai model is applied across the continent, including Nigeria, Uganda, Sierra Leone and Liberia. Godfery says they've trained more than 7,000 farmer-enterprisers and more than 30,000 people in total since it began.
Godfery believes zero waste agriculture is now steadily handling the issues about hunger, unemployment and environmental declines. And he wants to see it go further.
24.Which factor related to famine was unnoticed in Godfery's eyes
A.Poor soil.　　　　　　B.Water shortages.
C.Lack of resources.　　　　　　D.Unsustainability.
25.What does the author intend to do in Paragraph 3
A.Introduce a solution.
B.Give examples to the readers.
C.Add some background information.
D.Summarize the previous paragraphs.
26.How does “Songhai” help to ease the problem of famine
A.By offering land.　　　　　　B.By trading seeds.
C.By educating farmers.　　　　　　D.By selling technology.
27.Which of the following best describes Godfery
A.Critical and careful.
B.Learned and responsible.
C.Optimistic and generous.
D.Considerate and ambitious.
C
The San Diego County Water Authority has an unusual plan to use the city's scenic San Vicente Reservoir(水库) to store solar power so it's available after sunset. The project could help unlock America's clean energy future.
Perhaps ten years from now, if all goes smoothly, large underground pipes will connect this lake to a new reservoir, a much smaller one, built in a nearby valley about 1,100 feet higher. When the sun is high in the sky, California's abundant solar power will pump water into that upper reservoir. It's a way to store the electricity. When the sun goes down and solar power disappears,operators would open a valve(阀门) and the force of 8 million tons of water, falling back downhill through those same pipes, would drive machines capable of producing 500 megawatts of electricity for up to eight hours. That's enough to power 130,000 typical homes.
“It's a water battery!” says Neena Kuzmich, Deputy Director of Engineering for the water authority. She says energy storage facilities like these will be increasingly important as California starts to rely more on energy from wind and the sun, which can produce electricity on their own schedules, without considering the demands of consumers.
Californians learned this during a heat wave this past summer. “Everybody in the state of California got a text message at 5:30 in the evening to turn off their appliances,” Kuzmich says. The sun was going down, solar generation was disappearing, and the remaining power plants, many of them burning gas, couldn't keep up with demand. The reminder worked:People stopped using so much power, and the grid(输电网) survived.
Yet earlier that same day, there was so much solar power available that the grid couldn't take it all. Grid operators turned away more than 2,000 megawatts of electricity that solar generators could have delivered, enough to power a small city. That electricity was wasted. There was no way to store it for later, when operators desperately needed it.
28.What is the function of Paragraph 2
A.To present the importance of a reservoir.
B.To recall a situation in recent ten years.
C.To introduce the usage of solar energy.
D.To explain a way to store electricity.
29.What might Neena Kuzmich agree with
A.The reservoir serves to store energy.
B.Californians need little solar energy.
C.People used to waste too much energy.
D.New storage ways are environmentally friendly.
30.Why was a text message sent to everyone in California
A.To stop people working.
B.To warn people of danger.
C.To tell people the sunset time.
D.To remind people of lack of energy.
31.Which of the following is a suitable title for the text
A.Scenic San Vicente Reservoir
B.San Diego County Energy Plan
C.Water Batteries to Store Solar Power
D.Machines to Store Water in California
D
Close to the North Pole, the remote and rocky plateau mountain in the Norwegian archipelago of Svalbard seems an unlikely spot for any global effort to safeguard agriculture. In this cold and deserted environment, there are no grains, no gardens and no trees. But at the end of a 130-meter-long tunnel is a room filled with humanity's most precious treasure, the largest and most diverse seed collection—more than a half-billion seeds.
A quiet rescue mission is underway. With growing evidence that unchecked climate change will seriously affect food production and threaten the diversity of crops around the world, the Svalbard Global Seed Vault represents a major step towards ensuring the preservation of hundreds of thousands of crop varieties. This is a seed collection, but more importantly, it is a collection of the traits(特点)found within the seeds: the genes that give one variety resistance to a particular pest and another variety tolerance for hot, dry weather.
Few people will ever see or come into contact with the contents of this vault. In sealed(密封的)boxes, behind many locked doors, monitored by electronic security systems, enveloped in below-zero temperatures, and surrounded by tons of rocks, hundreds of millions of seeds are protected in their mountain fortress(堡垒). Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of keeping their ability to grow for thousands of years.
Everyone can look back now and say that the Seed Vault has been a good and obvious idea, and that of course the Norwegian government should have approved and funded it. But back in 2004, when the Seed Vault was first proposed, it was viewed as a crazy, impractical, and expensive idea.
We knew that nothing would provide a definite guarantee. But we were tired and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and the crops might be better prepared for change.
The Seed Vault is about hope and commitment—about what can be done if countries come together and work cooperatively to accomplish something significant, long-lasting, and worthy of who we are and wish to be.
32.According to the passage, what's the Seed Vault
A.It's a tunnel where the collected seeds are displayed.
B.It's a stone room that contains the seeds of endangered crops.
C.It's a seed gene bank that stores diverse seeds for future agriculture.
D.It's a lab where researchers study how to keep the diversity of crops.
33.What does the underlined word “viable” in Paragraph 3 refer to
A.Mature.　　　　　　B.Clean.
C.Alive.　　　　　　D.Valuable.
34.What is the third paragraph mainly about
A.How the seeds are preserved.
B.Where people keep the seeds.
C.Why the seeds are protected.
D.What people do to study the seeds.
35.We can know from the passage that　　　.
A.the Seed Vault offers a solution to climate change
B.the Seed Vault was built by many countries
C.the Seed Vault is sure to prevent the loss of crop diversity
D.many people considered building the Seed Vault unwise and crazy at first

But with rainwater, you'll never have to worry about these chemicals. After all, rainwater is a natural source of water. It generally won't harm plants. 　38　
It can protect your property (房产) from rain damage. Too much rain may damage your home. 　39　 This is especially true if your house doesn't have a water collecting system.
The system can help direct rainwater away from your home to where you want to collect it, which also prevents water from flooding in your neighborhood.
You'll help clean natural waterways. Rainwater helps the ground stay clean. But when it runs along rooftops, streets, etc., it collects many pollutants. 　40　 However, by collecting the water, you can prevent a considerable percentage of the pollutants from reaching the natural waterways in your hometown.

As the temperature approached as high as 90℉ last July 4th, three police officers went into a Whole Foods Market to get something 　41　 to drink.

All they saw were containers of 　44　.
“I'm hungry,” she explained 　45　. Caught red-handed, the woman no doubt was treated as a 　46　. But the police had other 　47　. “We'll pay for her food,” one of them told the 　48　 security guard. She would not be 　49　.
Drying her wet 　50　, the woman repeated, “Thank you, thank you.” She wasn't the only one touched by this act of 　51　. Customers at the store were so impressed by what they'd 　52　 that some even posted a photo on Twitter. 　53　, attention was never what the officers sought. They were 　54　 by a far more common emotion. When we look at someone's face and see that they need you, it's pretty 　55　 as a human being to walk away from something like this.

　　阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
One sunny afternoon in June, my sister Jenny and I were walking home from school when we noticed a loud chirp(鸟叫声) coming from an empty rubbish can beside the road. We walked over to the can and looked inside. We were surprised to find a little sparrow(麻雀) was sitting at the bottom of the trash can chirping sadly. His right wing stuck out of his body. Jenny said it was probably broken.
She reached in and cupped(捧着) the bird in her hands, comforting him. The bird chirped all the way to our house. My mom took one look at the bird and said, “No way! I'm not having another animal in the house.” But when she got a closer look, she felt sad about the bird.
Then Mom sent me into the bathroom for tape and gently set the bird on the kitchen table to get a better look at him. She said his right wing was surely broken, so she created a splint(夹板) and carefully taped it to the bird's wing. Our dog, Buttons, kept trying to get close to the bird, but we pushed her away.
Once the splint was on, we fed water and some bread to the bird. The little bird earned the name Peep. We kept him in a cage. Every night, we put a towel over the cage, and Peep went right to sleep. And every morning, we put his cage outside and opened the door so he could hang around and get some fresh air.
Peep couldn't fly, which seemed to disappoint him. He wasn't used to walking everywhere. Finally, Peep made friends with Buttons, and he would jump onto Buttons' back for a free ride around the backyard. Days later, Peep's wing got better. One night, Mom told us that it was probably time to take off the splint. With Mom's help, we cut off most of the splint. He didn't completely recover, so there were bits of white tape stuck to his wing, but he didn't seem to mind.
注意:续写词数应为150个左右。
Peep started pushing his wings up and down crazily, wanting to fly.







As it got dark, we believed that Peep would never fly back.

37.A　根据下文“Many people pay monthly for the water from the city water supply. Collecting rainwater can help you save part of that money.”可知,本段提到收集雨水可以帮你省下一部分钱,即减少水费,故A选项“这有助于减少你的水费”符合语境,故选A。
38.C　此空为本段最后一句,上文提到雨水不会伤害植物。故C选项“相反,它可以促进某些植物的生长”符合语境,故选C。
39.G　根据上文“It can protect your property from rain damage. Too much rain may damage your home.”和下文“This is especially true if your house doesn't have a water collecting system.”可知,本句承接上文就雨水破坏庭院进行举例,故G选项“例如,在雨季,暴雨可能会摧毁你的院子”符合语境,故选G。
40.E　根据上文“You'll help clean natural waterways. Rainwater helps the ground stay clean. But when it runs along rooftops, streets, etc., it collects many pollutants.”和下文“However, by collecting the water, you can prevent a considerable percentage of the pollutants from reaching the natural waterways in your hometown.”可知,本句承接上文说明后果,指出污水流入自然水道,与下文构成转折,故E选项“由此产生的脏水流入自然水道”符合语境,故选E。
第三部分　语言运用
第一节
　　◎语篇解读　本文是一篇记叙文,文章主要记叙了三名警察为一位因为饥饿而在商店里偷窃食物的妇女付钱的故事。他们的行为使这位妇女和在场的顾客都深受感动。
41.D　根据上文“as high as 90℉”可知,此处表示气温高,所以他们进来拿一些冷饮,故选D。

45.D　根据上文 “I'm hungry”可知,她太饿了,没办法才去偷窃,她被抓住审问,因此很无助地解释说,故选D。

47.C　结合下文警察为她付钱可知,警察有其他的想法,故选C。
48.B　警察的做法不常见,保安没想到警察会为那位妇女付钱,因此此处表示很吃惊,故选B。

第二节
　　◎语篇解读　本文是一篇说明文。文章主要介绍了大熊猫国家公园中大熊猫的相关信息以及为增加大熊猫数量而作出的努力。
56.which　考查非限制性定语从句。分析句子结构可知,所填词引导非限制性定语从句,从句缺少主语,先行词是The Giant Panda National Park,指物,因此使用关系代词which引导非限制性定语从句,故填which。
57.and　考查连词。“is in development”和“will include 67 existing panda reserves”之间为顺承关系,因此使用并列连词and。
58.a　考查冠词。此处意为“大熊猫是中国的一个象征”,表泛指,且symbol的发音以辅音音素开头,使用不定冠词a。
59.features　考查时态和主谓一致。此处叙述的是一般性事实,使用一般现在时,主语是This national park,谓语动词应用第三人称单数形式,故填features。
60.establishing　考查动名词。该空引出的短语与“Connecting...”短语并列作主语,使用所给词的动名词形式,故填establishing。
61.to help　考查动词不定式。an effort to do sth.意为“为做某事所作出的努力”,此处的动词不定式作后置定语,修饰名词effort,故填to help。
62.amazed　考查形容词。此处使用形容词作宾语补足语,且指人们“感到惊奇”,应用-ed形式的形容词,故填amazed。
63.from　考查介词。from...to...为固定搭配,意为“从……到……”,故填from。
64.incredibly　考查副词。设空处作状语修饰形容词positive,应用incredible的副词形式,故填incredibly。
65.survival　考查名词。根据空前的the和空后的of可知,此处用所给动词的名词形式作宾语,survival意为“生存”,故填survival。
第四部分　写作
第一节
One possible version:
Recently, citizens in our city have held a heated debate on whether we should explore the cultural site. Different people have different opinions.
Some people are in favor of the idea. They think the cultural site is worth exploring, which will make people learn more about the great history of our country. Besides, this cultural site can attract more visitors to our city, which will improve our tourism. However, others hold an opposite opinion that we should keep the cultural site as it is and protect it properly from being destroyed.
In my opinion, we should ask the experts for advice to make good use of this cultural site.
第二节
One possible version:
Peep started pushing his wings up and down crazily, wanting to fly. He was able to fly at last, though with some difficulty. We were happy for him even though he landed shortly after he had flown. Every morning he would fly, and gradually he would fly farther and farther. No matter how far he flew, he always came back. But at last one morning he flew away so far that we could not see him at all, and in the afternoon he did not come back.
As it got dark, we believed that Peep would never fly back. A few months later, Jenny and I were walking home from school when a bird landed in a low tree just in front of us. We both stopped and looked at it, amazed. The bird had little bits of white tape stuck to his right wing. Peep sat in the tree chirping at us for a couple of seconds, and then flew away. He had perhaps come back to say goodbye and to thank us for saving his life. We felt immensely satisfied.
