To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn’t a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater.
“Planting tress is one way, but it isn’t that simple. It doesn’t solve the basic issue of water resources,” says Wu Bo, a professor. “We need to calculate how much water the trees will absorb, or else it could have a negative effect.”
Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields(產(chǎn)量) using flood irrigation and earns a good income for his family.
Other farmers haven’t stuck it out(堅(jiān)持到底): about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return.
Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight.
“With enough water, this problem can be solved,” Lu says. “We can plant trees and grass, and they will grow bigger. That will stop the desert.”
Experts say that farmers could switch to drip irrigation (滴灌)to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to “Save Water, Protect the Environment”.
1. The negative effect of planting trees in deserts is that __________.
A. it can make groundwater become less
B. it can prevent the sand moving freely
C. it can stop crops growing well
D. it can get the soil to become poor
2.Why did Mr. Lu NOT accept the idea of relocation?
A. Because the plan of relocation will cost him much money.
B. Because his family had trouble moving away.
C. Because he was reluctant to give up his land.
D. Because he would rather stay than fight against the deserts.
3.What can we infer from the passage?
A. The deserts drive more and more people to leave their homes for their lives.
B. People have no means to fight against the land becoming desert.
C. Water is the biggest barrier for people to stop the desert.
D. Planting trees cannot solve the problem of desertification of farmland.
4.What advice is given by experts to save water?
A. To plant more trees.
B. To build greenhouses.
C. To change crops.
D. To use drip irrigation.

DEAR AMY: We recently had to put our cat down. It came out of the blue. We had no idea that he had health problems, and we woke up early one morning to the cat crying out painfully. We immediately rushed him to the vet’s where the vet said that at best treatment might lengthen his life by two to three months. We did not want to see him suffer, so we chose to kill the cat in a painless way.
I am having a rough time! I cry when I am alone. I cry when I see pet commercials on television. I put away everything that reminds me of the cat. But the last sight of seeing the cat in pain plays over and over in my head. My kids seem alright with what has happened, but why am I struggling?
It has only been one week since his passing, so I hope things will get better. Do you have any suggestions?
Yours,
Sad
DEAR SAD: There is no loss quite like the loss of a pet; these animals keep us company through important life passages and are beloved witnesses to our human lives.
I understand your instinct to put away all of your cat’s things, but it may help you now to memorialize your pet by using these things. Each family member can write down favorite things about him or memories of him; read their memories aloud and put the papers inside his bowl. The idea is to replace those painful last memories with much more lively memories taking place over the most of the animal’s life.
Time will then do its job, which is to affect your feelings. And then, when you’re ready, I hope you will adopt another animal and give it the opportunity to share your life.
Yours,
Amy

3.What does the underlined phrase mean in Paragraph 1?
A.In the color of blue. B.Very sadly.

4.What do we know from the last paragraph of Amy’s letter?

Catch yourself daydreaming while washing the dishes again? If this happens often you probably have a pretty capable working memory and a sharper brain, new research suggests.
This mind wandering, it seems, actually gives your working memory a workout. Working memory is the mental work space that allows the brain to juggle multiple thoughts at the same time. The more working memory a person has, the more daydreaming they can do without forgetting the task at hand.
Researchers studied groups of people from the University of Wisconsin-Madison community, ranging in age from 18 to 65. The volunteers were asked to perform simple tasks, like pressing a button every time they took a breath or clicking in response to a letter popping up on a computer screen; these tasks were so easy that their minds were likely to wander, the researchers figured.
The researchers checked in periodically, asking the participants if their minds were on task or wandering. When the task was over, they measured each participant's working memory capacity by having them remember letters while doing math questions. Though all participants performed well on the task, the researchers noticed that the individuals who indicated their minds had wandered more than others also scored higher on the working memory test.
“What this study seems to suggest is that, when circumstances for the task aren't very difficult, people who have additional working memory resources allocate them to think about things other than what they're doing,” said Jonathan Smallwood, a study researcher of the Max Planck Institute for Human Cognitive and Brain Science.
When our minds run out of working memory, these off-topic thoughts can take the main stage without us consciously meaning them to; for instance, arriving at home with no memory of the actual trip, or suddenly realizing that they've turned several pages in a book without understanding any of the words.
“It's almost like your attention was so absorbed in the mind wandering that there wasn't any left over to remember your goal to read,” study researcher Daniel Levinson, said in a statement. People with overall higher working memory were better able to stay focused when the task at hand required it. Those who had low working memory often had their thoughts drift away from the task, and did less well at it.
The findings add to past research suggesting these mind drifts can be positive moments. For instance, daydreaming has often been associated with creativity—researchers think that our most creative and inventive moments come when daydreaming. It's likely that the most intelligent among us also have high levels of working memory, Levinson noted.
1. The word “juggle” in the second paragraph can be replaced by “________”.
A. search B. understand C. handle D. foresee
2.What can be concluded from Jonathan Smallwood's words?
A. Absorbed in the mind wandering, your attention left no space for your goal.
B. On the working memory test, people with wandering minds will get high score.
C. Dealing with some easy jobs, people with higher working memory will daydream.
D. People who often have daydreams probably own a pretty capable working memory.
3. What is the best title of the passage?
A. Mind drifts are always positive.
B. Daydreaming is good for the mind.
C. Creative moments come with working memory.
D. The more daydreaming, the more effectively one works.

Most shoplifters (商店扒手)agree that the January sales offer wonderful opportunities for the hard-working thief. With the shops so crowded and the staff so busy, it does not require any extraordinary talent to help you to take one or two little things and escape unnoticed. It is known, in the business, as "hoisting".
But the hoisting game is not what it used to be. Even at the height of the sales, shoplifters today never know if they are being watched by one of those evil little balls(攝像頭)that hang from the ceilings of so many department stores above the most desirable goods.
As if that was not trouble enough for them, they can now be filmed at work and forced to attend a showing of their performance in court.
Selfridges was the first big London store to install videotape equipment to watch its sales floors. In October last year the store won its first court case for shoplifting using an evidence a videotape clearly showing a couple stealing dresses. It was an important test case which encouraged other stores to install similar equipment.
When the balls first make an appearance in shops, it was widely believed that their only function was to frighten shoplifters. Their somewhat ridiculous appearances, the curious holes and red lights going on and off, certainly make the theory believable.
It did not take long, however, for serious shoplifters to start showing suitable respect. Soon after the equipment was in operation at Selfridges, store detective Brian Chadwick was sitting in the control room watching a woman secretly putting bottles of perfume(香水)into her bag.
"As she turned to go," Chadwick recalled, "she suddenly looked up at the 'balls' and stopped. She could not possibly have seen that the camera was trained on her because it is completely hidden, but she must have had a feeling that I was looking at her."
"For a moment she paused, but then she returned to counter and started putting everything back. When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store."
1. January is a good month for shoplifters because ________.
A they don't need to wait for staff to serve them
B they don't need any previous experience as thieves
C there are so many people in the store
D January sales offer wonderful opportunities for them
2.The case last October was important because ________ .
A. the store got the dresses back
B .the equipment was able to frighten shoplifters
C. other shops found out about the equipment
D. the kind of evidence supplied was accepted by court
3.The woman stealing perfume ________.
A. guessed that the detective had seen her
B. was frightened by its shape
C. could see the camera filming
D. knew that the balls were for her
4. The woman's action before leaving the store shows that she ________.
A. was sorry for what she had done
B. was afraid she would be arrested
C. decided she didn't want what she had picked up
D. wanted to prove she had not intended to steal anything
