The Israeli farmers who pioneered the revolutionary technology known as drip irrigation weren’t trying to solve one of the world’s most urgent problems.They were just trying to survive.They lived in the desert,and they didn’t have enough water to grow their crops.

In its simplest form,it was little more than a pipe with holes in it.But behind each hole was a hi-tech dripper that let out just the fight amount of water.Snaked along a row of crops so that the holes were positioned directly above the roots,the pipe could direct each precious drop of water directly to the plants,getting a bigger harvest while using a very small amount of the water.

Over time,the farmers improved upon the technology,perfecting the drippers that regulated the flow of water,and connecting the pipelines to computers that could determine exactly how much water each plant needed and when.

If the global population kept growing,the rest of the world would increasingly resemble their little community in the desert.So they began selling their irrigation systems in other parts of the world,eventually expanding to more than 110 countries.Netafirm,the company says it’s lifting people out of poverty and conserving water at a time when the importance of doing so has never been clearer.

The mass adoption of drip irrigation won’t save the world by itself.To avoid the coming catastrophe,nearly everybody will,in some way,have to do more with less,perhaps through accepting and using other new technologies.Otherwise,it’s going to get ugly.

Veteran(经验丰富的)rock climbers are calling her one of the most promising climbers in the world. She flies up, grasping the rock and heading gracefully for practically non-existent(不存在的)holds. She’s only 14. Ashima Shiraishi, the New York-born teen, has shaken up the climbing world. At 1.55 meters and 45 kilograms, Ashima might not look like the groundbreaking athlete. But she could be, though still young, the first female climber whose accomplishments go beyond gender.

The evidence: At just 14, Ashima has already made history in the sport. She won the American National Youth Bouldering Championship(美国青少年攀岩锦标赛)every year from 2010 to 2014. And last March, the young climber completed the “Open Your Mind Direct” course in Spain. It’s a very big deal because the course, with a hold broken off near the top, is widely considered one of the hardest in the world. Only one woman and a small number of men have ever conquered it. She first learned to climb on rocks in Central Park when she was only six. Her father, who works as a dancer, is her coach. At age nine, Ashima went on a bouldering(攀岩)trip to Texas. Falling brought tears to her eyes, but she didn’t give up. Now, she finds she “couldn’t live without climbing.”

For the past six years, Ashima has been a climbing legend. Her love for the sport has taken her around the world. There have been articles and photo spreads(横贯两版的照片)in newspapers and sports magazines, films, countless online video clips, and an appearance on Time Magazine’s list of America’s most influential teenagers.

“I think people are shocked if I do something they can’t do or because I’m still very young and I’m a girl,” Ashima says. “In most sports, men lead the way. But with climbing, who knows, maybe women will be leading. Doing something that a guy can’t do is pretty special.”

1.As for Ashima Shiraishi, we know ________.

A. she is a great young rock climber

B. she can always find climbing holds that don’t exist

C. she doesn’t look like an athlete at all

D. she is the first female climber in the world

2.Which of the following is true about the course “Open your Mind Direct”?

A. Climbers can take the course only in Spain and America.

B. It is not difficult to finish the course.

C. Climbers have to finish it without any holds at near the top.

D. Not many climbers have done well in it.

3.From the last paragraph, we can infer that ________.

A. she wants to try other events in sports

B. she wonders why people are shocked

C. she expects to do better in rock climbing

D. she decides to try anything men can do

4.The passage mainly focuses on ________.

A. A Rock Star in the Climbing World

B. The First Female Rock Climber

C. A Most Influential Teenager in America

D. The Champion of American National Youth

Attention to detail is something everyone can and should do — especially in tight job market.

Bob Crossley, a human-resources expert notices this in the job applications that come across his desk every day. “It’s amazing how many candidates eliminate (淘汰) themselves,” he says. “Resumes (简历) arrive with faults. Some candidates don’t bother to spell the company’s name correctly. Once I see a mistake, I refuse the candidates,” Crossley concludes,” If they cannot take care of these details, why should we trust them with a job?”

Can we pay too much attention to details? Absolutely not.

Perfectionists(完美主义者) struggle over little things instead of something larger they work toward. “To keep from losing the forest for the trees,” says Charles Garfield, the professor at the University of California, San Francisco, “We must constantly ask ourselves how the details we’re working will influence the larger picture. If they don’t, we should drop them and move to something else.”

Garfield compares this process to his work as a computer scientist at NASA. “The Apollo II moon launch was slightly off-course 90 percent of the time,” says Garfield. “But a successful landing was still likely because we knew the exact position of our goal. This allowed us to make adjustments as necessary.” Knowing where to go helps us judge the importance of every task we undertake.

Again and again, we see that by doing little things within our grasp well, large rewards follow.

1.According to the passage, some job applicants were refused because they are ________.

A. too limitedly educated to write a perfect resume

B. so careless that they make some spelling mistakes in their resume

C. so careless that they forget the company’s name

D. too foolish to spell the company’s name correctly

2.From the passage, we can infer that a perfectionist will _________.

A. change their goals as the situations change

B. lose their jobs by paying too much attention to details

C. pay attention to details as much as to their major goals

D. pay attention to details more than their major goals

3.Garfield makes his opinion believable by _________.

A. giving ideas of experts

B. offering examples of resumes

C. providing an example of his work.

D. showing the results of experiments

4.Which of the following best shows the structure of the passage?

I: Introduction P:Point Sp: Sub-point (次要点)C: Conclusion

Facebook is the world’s biggest social networking site. People are being tricked into Facebook with the promise of a fun, free service without realizing they’re paying for it by giving up loads of personal information.

Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Facebook because people don’t really know what their personal data is worth.

The biggest problem, however, is that the company keeps changing the rules. Early you could keep everything private. That was the great thing about Facebook— You could create your own little private network. Last year, the company changed its privacy rules so that many things— your city, your photo, your friends’ names— were set by default (默认)to be shared with everyone on the Internet.

According to Facebook’s vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information, they have a “less satisfying experience”.

Some critics(批评家) think this is more about Facebook looking to make more money. In original business model, which involved selling ads and putting them in the side of the pages totally, who wants to look at ads when they’re online connecting with their friends?

The privacy issue has already landed Facebook in hot water in Washington. In April,Senator Charles Schumer called on Facebook to change its privacy policy. He also urged(催促) the Federal Trade Commission to set guidelines for social networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.

I suspect that whatever Facebook has done so far to invade our privacy, it’s only the beginning,which is why I’m considering cancelling(取消)my account.Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t know. That’s too high a price to pay.

1.What do we learn about Facebook from the first paragraph?
