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（产量） using flood irrigation and earns a good income for his family.

    Other farmers haven't stuck it out（坚持到底）: 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”.

Forget Cyclists, Pedestrians are Real Danger

We are having a debate about this topic. Here are some letters from our readers.

■ Yes, many cyclists behave dangerously. Many drivers are disrespectful of cyclists But pedestrians are probably the worse offenders.

People of all ages happily walk along the pavement with eyes and hands glued to the mobile phone, quite unaware of what is going on around them. They may even do the same thing while crossing a road at a pedestrian crossing or elsewhere. The rest of us have to evade (避让) them or just stand still to wait for the unavoidable collision.

The real problem is that some pedestrians seem to be, at least for the moment, in worlds of their own that are, to them, much more important than the welfare of others.

——Michael Horan

■ I loved the letter from Bob Brooks about cyclists (Viewpoints, May 29). I am afraid they seem to think they own the roads.

I was walking across Altrincharn Road one morning when a cyclist went round me and on being asked what he was doing he shouted at me.

The government built a cycle lane on the road but it is hardly used.

The police do nothing. What a laugh they are!

The cyclists should all have to be made to use the cycle lanes and wear helmets, fluorescent (发荧光的)jacket and tights at night and in the morning. They should pay some sort of tax and be fined for not wearing them.

——Carol Harvey

■ Cyclists jump on and off pavements (which are meant for pedestrians), ride at speed along the pavements, and think they have a special right to go through traffic lights when they are on red.

I was almost knocked down recently by a cyclist riding on the pavement when there was a cycle lane right next to him.

Other road users, including horse riders, manage to obey the rules so why not cyclists?

It's about time they had to be registered and insured, so when they do hit a pedestrian or a vehicle, or cause an accident, at least they can be traced and there might be an opportunity to claim.

    NEW YORK—Australian mining enterpriser Clive Palmer on Tuesday unveiled(公布) blueprints (蓝本) for Titanic Ⅱ, a modern copy of the doomed ocean liner, although he didn't call the ship unsinkable any more.

    The ship will largely recreate the design and decoration of the fabled original, with some modifications to keep it in line with current safety rules and shipbuilding practices, and the addition of some modern comforts such as air conditioning, Palmer said at a press conference in New York.

    The three passenger classes, however, will be prevented from mingling(混杂), as in 1912, Palmer said. “I'm not too superstitious(迷信的). ”Palmer said when asked whether recreating a ship best-known for sinking was tempting fate.

    White Star Line, the operator of the original ship, had said the Titanic was designed to be unsinkable. About 1, 500 people died on Titanic's maiden voyage in 1912 from Southampton to New York after the ship collided with an iceberg in the North Atlantic.

    Palmer, who created the company Blue Star Line last year, refused to make a similar boast.

    “Anything will sink if you put a hole in it,”Palmer said. “I think it would be very cavalier(漫不经心的) to say it.”

    Unlike the original, TitanicⅡ will have more than enough space in its lifeboats for every person on board and will have additional escape staircases. Markku Kanerva, sales director at Deltamarin, the Finnish company designing the ship, said it would be “the safest cruise ship in the world”.

    Palmer refused to answer questions about the project's cost. Although the Titanic was the world's largest ship in her time, she would be smaller than many of today's modern cruise ships.

    “It's not about the money, ”Palmer said. “I've got enough money for it. I think that's all that matters.”

    Forbes estimated Palmer's net worth to be $795 million in 2012. He describes himself as a billionaire.

    TitanicⅡ will be built by Chinese state-owned CSC Jinling Shipyard, which has already built four ore carriers for Palmer's mining business, he said. The contract to build TitanicⅡ has not yet been signed, Palmer said.

    One day, a poor man, who had only one piece of bread to eat, was walking past a restaurant. There was a large pot of soup on the table. The poor man held his bread over the soup, so the steam from the soup went into the bread, and gave it a good smell. Then he ate the bread.

    The restaurant owner was very angry at this, and he asked the man for money, in exchange for the steam from the soup. The poor man had no money, so the restaurant owner took him to Nasreddin, who was a judge at that time. Nasreddin thought about the case for a little while.

    Then he took some money from his pocket. He held the coins next to the restaurant owner's ear, and shook them, so that they made a dingling (叮当声) noise.

    “What was that?” asked the restaurant owner.

    “That was payment for you,” answered Nasreddin.

    “What do you mean? That was just the sound of coins!” said angrily the restaurant owner.

    “The sound of the coin is payment for the smell of the soup,” answered Nasreddin. “Now go back to your restaurant.”

    John is a mechanic, but he lost his job a few months ago. He has good heart, but always feared applying for a new job.

    One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 am and it was already 8:30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tyre(轮胎) of his car. Obviously there was something wrong with the car. John immediately went up to lend him a hand. When John finished working on the car, the old man asked him how much he should pay for the service. John said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, "Well, I could take you to the office for your interview. It's the least I could do. Please. I insist." John agreed.

    Upon arrival, John found a long line of applications waiting to be interviewed. John still had some grease(油脂) on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer's office with disappointed look on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked, "Do you really need to be interviewed?" John's heart sank. "With the way I look now, how could I possibly pass this interview?" he thought to himself.

    Then the interviewer turned the chair and to John's surprise, it was the old man he helped earlier in the morning. It turned out he was the General Manager of the company.

    "Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as part of our workforce before you even stepped into the office. I just know you'd be a trustworthy worker. Congratulations!" John sat down and they shared a cup of well-deserved coffee as he landed himself a new job.
