    Like many countries, Britain has serious environmental problems. In 1952, more than 4, 000 people died in London because of the smog(雾霾). The government made new laws to stop smog from coal(煤) fires and factories and things became better.

    Today, London is much cleaner but there is a new problem：smog from cars. In December 1991, there was very little wind in London and pollution was much worse. As a result, about 160 people died from pollution in just four days.

    Part of the problem is the new "out of town" shopping centers. In the past, people often walked to shops near their home or went by bus. Now, many people drive to the new shopping centers. As a result, the small shops have been closed and more people have to travel to do their shopping.

    Many people think that Britain needs better and cheaper public transport(交通). Transport in Britain is very expensive. An early morning train trip from Glasgow to London(about 600km)can cost about 100 pounds, for example. A short 15-minute bus trip can cost over 100 pound.

    Many people are trying to cut the use of cars in Britain. Some cities now have special bicycle paths and many people cycle to work. Some people also travel to work together in one car to make less the pollution and the cost.

    While you are at the bookstore, you may be faced with a difficult decision: e-books or paper books? Each one has its advantages and disadvantages. Making the best decision depends on a number of factor (因素).

    An e-reader can carry a whole library wherever you go, which is great for travelers or those who always want a choice of reading material Although e-readers are convenient, high levels of screen brightness from an electronic device(电子设备) can cause eye problems. A study in the Information Science Research found that young people preferred e-readers, like smart phones or iPads. That's why most teenagers are short-sighted.

    Many book lovers still prefer paper books and value the feeling of them. Paper books are very well designed, they look and smell good, and they carry with them a more human touch. Avid (热衷的)readers prefer reading on paper. Perhaps this is their choice because paper books give them a sense of ownership. It is reported that reading on paper rather than an electronic screen is better for memory and focus. But paper books are heavy and they are not convenient to carry.

    Which is your decision, an e-book or a paper book?
