Scientists are working to develop crop plants that can reduce the amount of water used for agriculture. Almost sixty percent of the world’s freshwater withdrawals from rivers, lakes and other water resources go toward irrigating fields.
Scientists are using biotechnology as well as traditional breeding methods to develop water-saving crops to feed a growing world.
Thomas “Tommy” Carter is a plant scientist in North Carolina. He works for the Agricultural Research Service in the United States Department of Agriculture. He leads Team Drought, a group of researchers at five universities. They have been using conventional breeding methods to develop and test soybeans that can grow well under dry conditions.
Tommy Carter started working on drought-resistant soybeans in 1981. His research has taken him as far as China, where soybeans have been grown for thousands of years.
Farmers in the United States, however, have grown soybeans for only about a century. Tommy Carter says the soybeans they grow are for the most part genetically similar. More differences could better protect crops against climate changes that can reduce production. Those changes include water shortages which could increase from global warming.
The Agriculture Department has a soybean germplasm(胚质) collection, a collection of genetic material passed from one generation to the next. Members of Team Drought studied more than 2,500 examples from the collection.
They looked at ones from the home of soybeans, Asia. They searched for germplasms that could keep plants from weakening and wilting (凋谢)during hot, dry summers in the United States.
Tommy Carter says they found only five. But these slow-wilting lines, he says, produce four to eight bushels（英斗）more than normal soybeans under drought conditions. The yield depends on location and environment.
Scientists are also working on other plants that either use less water or use it better, or both. For example, companies like Monsanto, DuPont and Syngenta have been developing corn with reduced water needs. Monsanto expects to be ready in a few years to market its first corn seeds genetically engineered to resist drought.

At least 115 Chinese miners have been pulled alive from a flooded coal mine after more than seven days trapped underground.
Rescuers cheered and some shed tears as the latest survivors emerged alive Monday after more than a week trapped in a flooded mine in north China's Shanxi Province. Officials were also relieved as their round-the-clock rescue mission prevented one of the country's worst mining disasters.
The head of the province's Work Safety ministry, Luo Lin, was among thousands of relatives waiting desperately for news at the pit entrance after rescuers said they had heard voices deep within the mine shaft over the weekend.
It is a miracle in China's mining rescue history, Luo says. He thanked the rescuers for their effort as he counted the miners leaving the entrance.
By late evening Monday, 115 miners had been pulled out alive, China's state media said. They were led to waiting ambulances with their eyes covered to prevent the glare from lights. All are said to be in a stable condition after being trapped in water for nearly nine days. They were able to breathe during their ordeal thanks to air pockets.
Three-thousand rescuers dug and pumped water for seven days to reach the miners at the Wangjialing Coal Mine, which is considered a modern facility.
The first survivors were brought to the surface shortly after midnight on Monday. Attempts to reach the 38 who remain trapped are continuing.
153 people were believed to be trapped underground. But families say this is an underestimate, claiming many more were working in the mine at the time of the flooding.
A preliminary investigation last week found that officials had ignored reports of water leaks prior to the accident.
China relies heavily on coal to fuel its booming economy. But it has some of the most dangerous mines in the world, with many mine bosses ignoring safety concerns to meet demand and chase profits.
The government has sought to improve safety in recent years by clamping down on illegal mines and this seems to have prevented many deaths.
According to official figures, 2,631 coal miners died in 1,616 mine accidents in China in 2009 – down 18 percent from the previous year.
1. Which is the best title of the passage?
A. The Flooded Coal Mine
B. Miners Trapped were Saved
C. The Worst Coal Mine Accident
D. 115 Miners Rescued, 38 Still Missing
2. The underlined word “round-the-clock” in Para 2 most probably means “_______”.
A. finishing before a particular time
B. changing the time shown by clock
C. all day and all night without stopping
D. from the beginning to the end
3. Which of the following is True according to the passage?
A. Coal plays a decisive role in China’s economy.
B. Mine accidents have been increasing in recent years.
C. 115 miners were working underground when the flooding happened.
D. About 3200 coal miners died in mine accidents in China in 2008.
4. At least 115 coal miners were rescued _______.
A. on the day the accident happened
B. after more than 7 days trapped underground
C. after working underground for 9 days
D. 10 days after the accident happened

“Can I see my baby?” asked the happy new mother. The bundle(婴儿包) was placed in her arms and when she moved the fold of cloth to look upon his tiny face, she gasped—the baby had been born without ears. Time, however, proved that the baby’s hearing was perfect except his appearance.
One day when he rushed home from school and threw himself into his mother’s arms, he cried out bitterly, “A boy, a big boy called me—a f-…freak.” She sighed, knowing that his life was to be endless of heartbreaks.
He grew up, handsome for his misfortune. A favorite with his fellow students, he might have been class president, but for that. He developed a gift for literature and music.
The boy’s father had a talk with the family doctor. Could nothing be done? “I believe we could graft(移植) on a pair of outer ears, if they could be donated,” the doctor decided. So the search began for a person who would make such a sacrifice for a young man. Two years went by. “You’re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’s a secret,” said the father.
The operation was a brilliant success. His talents blossomed into genius. School and college became a series of successes. Later he married and entered the diplomatic(外交) service. “But I must know!” he urged his father. “Who gave so much for me? I could never do enough for him.”
“I do not believe you could,” said the father, “but the agreement was that you are not to know…, not yet.” The years kept the secret, but the day did come… one of the darkest days that ever pass through a son. He stood with his father over his mother’s casket(棺材). Slowly and tenderly, the father stretched forth a hand and raised the thick, reddish-brown hair to let out the secret.

阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。
In a memory – based competition between you and a chimp (猩猩); who do you think would win? If you put yourself on top, you might want to guess again.
In a test that challenged participants to remember numbers, a young chimp performed better than Japanese college students.
Here's how the test worked. At Kyoto University in Japan, human students and chimpanzee participants sat in front of a computer. Five numbers, ranging from 1 to 9, were combined with one another and then, they appeared at random places on the screen.
The numbers stayed on the screen for less than a second. In the first test, for example, participants saw the numbers for 650 milliseconds (about two- thirds of a second).
Then, each number disappeared and they saw a white square instead. Participants had to touch the squares in numerical order, based on the numbers that had been there a moment before.
In this test, the students touched the boxes in the correct order about 80 percent of the time. A young chimp named Ayumu performed equally well.
During a harder test, participants were only able to see the numbers for 210 milliseconds.
This time, students only succeeded in putting the boxes in the correct order about 40 percent of the time. But Ayumustill could select the boxes in the right order nearly 80 percent of the time.
Some people have what's called a "photographic memory", which allows them to remember a surprising number of details after just a quick glimpse of something. Ayumu's memory might work in a similar way, says lead researcher Tetsuro Matsuzawa.
The chimp's young age might have something to do with his impressive performance, too. In previous tests, the Japanese researchers found that young chimps performed better than their mothers.
The scientists are interested to see whether Ayumu loses his strong memory as he arrows older. They already know that young children sometimes have sharp memories when offered something photographical, but they lose this ability over time.

Topic	A (76) competition between human beings and chimps
Purpose	To judge whose memory is better
The (77) of the first test	◆A chimp and some Japanese students participated in the competition and sat before a computer. ◆Different (78) of five numbers appeared on the screen. ◆Each of the number was (79) by a white square.
