London used to be “foggy”( 有雾的) for the same reason that cities like Beijing or Chongqing are “foggy” today. The “fog” was in fact smog(烟雾), a mixture of smoke and fog.In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. Within a few years, the air became much cleaner. There were no more “pea-soupers”.

Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive.

However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.

Reading is good for you. There is increasing evidence to show that reading isn’t merely a way of improving literacy and knowledge, but that it might actually be good for one’s mental and physical health, too.

In the age of Twitter and short attention spans, reading novels, which requires intense concentration over a long period of time, could be the antidote(矫正方法).

Neuroscientists Baroness Susan Greenfield says that reading helps to lengthen attention spans in children and improve their ability to think clearly. “Stories have a structure that encourages our brain to think in sequence, to link cause, effect and significance,” she says “It is essential to learn this skill as a small child.”

“In a computer game, you might rescue a princess, but you don’t care about her, you just want to win,” she explains, “But a princess in a book has a past, present and future. You can relate to her. You see the world through her eyes”

According to professor John Stein, Oxford university, reading is far from a passive activity. “Reading exercises the whole brain,” he explains. “ When we get lost in a good book, we are doing more than following a story, Imaging what is happening is as good as activating the brain as doing it. In other words, our brains simulate(模仿) real experiences, and it is just as if we were experiencing them ourselves. This doesn’t happen when we are watching a TV or playing computer games.”

Getting stuck in a good novel appears to be good for one’s mental health. Reading helps one not only fights loneliness, but also forget one’s own problems for a while.

Researchers found that just six minutes of reading could reduce stress levels by more than two-thirds, more than listening to music or going out for a walk. The concentration required to read distracts the mind, easing muscle’s tension and slowing the heart rate. Reading may be good for physical health, too, by preventing brain aging and disease.
