题目列表(包括答案和解析)
500 years ago in Britain, the burning of coal (煤) was increasing in cities like London. Coal was used in factories and also used to heat homes. Coal, when burnt makes a lot of smoke, which makes the air very dirty.
About 200 years ago, the Industrial Revolution (工业革命) began in Britain. Factories were built, and even more coal was burnt. Air pollution was becoming a really big problem.
Smoke and fog together make smog (烟雾). Smog was a big problem in London's winter. Because of the cold weather, more coal was burnt to warm houses and this made more smoke.
When smog stayed over a city, it became really hard to breathe and see clearly. In 1952, the Great London Smog happened and more than 4,000 people died because of the smog.
New laws (法律) were made in 1956 and 1968 to stop such sad things from happening again. These laws were called the Clean Air Acts.
These laws were made so that air would become cleaner. The laws encouraged people to use less coal or switch to other fuels such as gas. Factories started using tall chimneys (烟囱) so that the smoke would go high up in the sky and no longer cover cities, and new factories were built in the countryside. Smog appeared less often and the air became cleaner.

What a cold winter! How wonderful it would be if there was a fire! Fire keeps us warm．But fire is very dangerous, and can kill us．
November 9 was National Fire Safety Day．It's a time for us to learn a lot more about fire, especially(特别是)what to do if we are caught in a fire．
If you smell smoke or see fire, shout out“Fire”! Shout(大喊)as loudly as you can, because people may be asleep．
Never try to put out a fire yourself, even if it is a very small one! Get help from your parents or call 1－1－9．Tell 119 where you are and what is on fire．Listen to 119's instructions(指导)．
If there is a lot of smoke in your room, keep down close to the floor．There is less smoke down there, so it's easier to breathe(呼吸)and see where you are going．If you don't, the smoke may kill you before the fire does．
Test the door before you open it．Touch it with the back of your hand near the top．If the door is cool, open it carefully．If the door is hot, do not open it! Try to find a different way out．
Most home fires start at night when people are asleep．So, always close your bedroom door before sleep．It can keep the fire out．
If you can, get out of your home as soon as you can．Do not stop to pick up anything．A fire can become very big in a few seconds!
Never use the lift during a fire．Always use the stairs．A lift may stop at a floor where the fire is burning．It may also go wrong and keep you inside．
Never go back into a burning building! Even if you have left your pet of favorite toy inside, do not go back for it．Don't worry about your pets．Animals have a very good sense of smell．They often get out of building before people!
