    There was a boss who made a contract with his workers: he will pay their salary each week, but not in cash. Instead, the workers would choose some goods in a shop, which equal the value of their salary. Then he will pay the cash to the owner of the shop.

    But one day, one of the workers complained to his boss, “The shop owner said 'no cash, no goods'. And he requested us to pay in cash.” For that reason, the worker asked the boss to pay him in cash, too. The boss agreed. After a while, the shop owner came to the boss, asking him to pay for his workers.

    The boss was confused and looked into the issue, and finally found out that the worker told a lie. However, he paid the shop owner as usual, because he must keep his promise, even he was cheated and had to pay more money.

    Good merchants won't scrap(废除)their contracts. They won't sign contracts easily and usually chaffer(论价)for their benefits if they have to sign them. But after that, they will definitely follow them whatever the price.

Teens' Sleep Shortage

    Most teens need about 8 to more than 9 hours of sleep each night. The right amount of sleep is essential for anyone who wants to do well in tests or sports. And lack of sleep affects everything from a person's ability to pay attention in class to his or her mood. It also damages teens' ability to do their best in athletics. Unfortunately, research shows that many teens don't get enough sleep, and more than 20% of high school students fall asleep in class.

    Until recently, teens were often blamed for staying up late, oversleeping for school, and falling asleep in class. But recent studies show that teens' sleep patterns actually differ from those of adults or kids. These studies show that during the teen years, the body's biological clock is temporarily reset, telling a person to fall asleep later and wake up later. This change might arise from the fact that the brain hormone melatonin (褪黑素) is produced later at night for teens than it is for kids and adults. This can make it harder for teens to fall asleep early.

    These changes in the body's biological clock are in line with a time when they're busier than ever. For most teens, the pressure to do well in school is heavier than when they were kids, and it's harder to get by without studying hard. And teens also have other time demands — everything from sports and other extracurricular(课程外的) activities to fitting in a part-time job to save money for college.

    Early start time in some schools may also play a role in this sleep shortage. Teens who fall asleep after midnight may still have to get up early for school, meaning that they may only squeeze in 6 or 7 hours of sleep a night. A couple hours of missed sleep a night may not seem like a big deal, but can create a noticeable sleep shortage over time

Whatever happened to the fight of carbon capture?

Debates have been going on around the subject of carbon capture. Scientists, especially engineers and geologists, have strongly criticized green groups who claimed that carbon capture and storage (CCS) schemes are costly mistakes.

The scientists insisted that such schemes are vital weapons in the battle against global heating. They also wan that failure to set up ways to trap and store carbon would make it impossible to meet the emissions target by 2050." CCS is going to be the only effective way in the short term to prevent our steel industry, cement manufacture and many other processes from continuing to pour emissions into the atmosphere," said Professor Stuart Haszeldine, of Edinburgh University. "If we are to have any hope of keeping global temperature increases down below 2 degrees Celsius, we desperately need to develop ways to capture and store carbon dioxide."

Green groups claimed CCS would not make "a meaningful contribution to 2050 climate targets". They say CCS was not a reliable way to decarbonize the energy system and that CCS has a "history of over-promising and under-delivering". Instead, they urged the construction of more renewable energy plants to be given priority.

But the claims were dismissed by engineers and geologists, "These claims are quite unfair" said Michael Stephenson, director at the British Geological Survey. "The technology behind carbon capture and storage is fully mature. It offers us a genuine solution to some of the problems we face in trying to deal with global warming."

A government spokesman for the Department of Energy and Climate Change said, "We are committed to meeting our climate change targets in a way that is affordable and provides secure energy to families and businesses. We are considering the role that CCS could play in decarbonization of the UK. But we also need to take government spending into account. CCS had better come down in cost."
