Two months ago, I asked a group of kids in a school, "Why do we have to study math or other subjects？Your parents also studied these things, but are they using them？" They must be surprised when asked this question.
Take this as an example. When you go to a gym, you do some exercises. Maybe you lift weights or do something else. Why do you do that? The reason why you do these exercises is to build your strength and improve your health.
Similarly, the reason why you study math or any other subject is that they help develop logical thinking(逻辑思维), and help you make sense of the world. By studying, you are able to build mental models about the world, so that you can respond(回应) to situations more smartly than a monkey would be.
Learning to your mind is as exercise to your body. If you want to keep healthy and make your body strong, you should do exercises often. So if you want to improve your intelligence(智力), you should try your best to study hard on every subject. Besides, something that you are studying may seems useless now. But when you need to use it someday, you will be regretful if you cannot use it because you don't study it well now.
That is my answer to this question. Kids should be encouraged to ask more about these questions and learn math and other subjects well so that they will become good at thinking.
In common with other countries, Britain has serious environmental problems. In 1952, more than 4,000 people died in London because of the smog. The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot.
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 increased a lot. As a result, about 160 people died from pollution in just four days.
One of the problem is the new "out of town" shopping centres. In the past, people often walked to shops near their homes or went by bus. Now, many people drive to the new shopping centres. Because the small shops have disappeared in the downtown, more people have to travel to do their shopping.
Critics say that Britain needs better and cheaper public transport. Transport in Britain is very expensive. An early morning train trip from Glasgow to London (about 600km) can cost about £100, for example. A short 15-minute bus trip can cost over £1.00.
Many people are trying to reduce 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 reduce the pollution and the cost.
