In Britain, the climate is not very good. There are very few hot days and it rains a lot. Because of this, people spend a lot of time at home. Generally, British homes have a lot of furniture in them, carpets on the floors and heavy curtains.

   Many houses in Britain are old. Many of them are over one hundred years old. Often, they do not have enough insulation and the heat goes out through the windows, the doors and up the chimney.

   Because of the climate, people in Britain have to send a lot of money on heating. Many houses have special system called “central heating”. The heats all the rooms and, at the same time, heats the hot water. Houses without central heating often have gas, electric or coal fires. The rooms in most British houses are quite small.

   New houses are much better. They have two layers of glass in the windows to stop the heat going out.

   Energy is one of the problems that many people are interested in. It is not an unfamiliar word. It is heard, said, discussed day after day. It is close to everyone’s daily life. You turn on a lamp and it is energy that gives you light. You turn on a TV and it is energy that gives you pictures and sound. You ride a motorcycle and it is energy that gives you movement. You cook your meals and it is energy that gives you heat to boil rice.

   The problem is that the demand for energy is rising and that the price of energy is getting higher and higher. The supply of energy on earth is limited. It cannot provide us forever. The shortage of energy in the future is inevitable. Therefore, saving energy is a must if we want to continue to live in a safe and sound world.

Many people still believe that natural resources will never be used up. Actually, the world’s energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of power. According to Professor Marvin Burnharm of the New England Institude of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power is the only alternative.

   However, many people do not approve of using nuclear power because it’s very dangerous. What would happen if there was a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations.

   The most effective thing is that we should use natural resources as economical as possible.

“...Bấy giờ ai nấy ở trong đình, đều nôn nao sợ hãi. Thốt nhiên một người nhà quê, mình mẩy lấm láp, quần áo ướt đầm, tất tả chạy xông vào thở không ra lời:

- Bẩm ... quan lớn... đê vỡ mất rồi ! Quan lớn đỏ mặt tía tai, quay ra quát rằng:

- Đê vỡ rồi !... Đê vỡ rồi, thời ông cách cổ chúng mày, thời ông bỏ tù chúng mày !

Có biết không?... Lính đâu? Sao bay dám để cho nó chạy xồng xộc vào đây như vậy? Không còn phép tắc gì nữa à?

- Dạ, bẩm...

- Đuổi cổ nó ra !”
