Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition(眼睛识别) program is already being tested in shops and banks in the USA, Britain and France. Soon, this technology(技术) will change all other ways of finding out who people are.
However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hands or even your smell! We already have machines that can tell who you are from your voice or the mark made by your fingers.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the program can be up to 94％ correct, depending on(依靠) how good the technology is. Some programs may only be right 51％ of the time. In Britain, it was found that 91％ of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking at you in the eye. So smile!
【小题1】 How does the eye-recognition program work?

I read an article about London in a m   1.   yesterday.

London is one of the c   2.   with a long history in Britain. It is also the biggest  city in Europe. You can find some of the best theatres of the world there, such as the National Theatre, the National Gallery(画廊) and so on. You may visit many places of i   3.  there. Most of the old and f  4.  buildings are on the n  5.  bank of the River Thames. On the south bank, there are some fine modern  buildings.

  When you are about to do something brave, a cheerful wish of "Good luck!" from a friend can be helpful. But if you think you need lots of luck, what else might you do?
In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer.
Have you heard the saying “when you wish upon a star”? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star! Seeing one doesn't happen very often. The saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true.
Maybe you have heard of the lucky rabbit's foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit's feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, "Depend on the rabbit's foot if you will, but remember it didn't work for the rabbit!"
People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch the leaves as they fall because they think each leaf they catch will bring them a lucky month in the following year ,theywill need to catch 12 falling leaves to have a whole year of good luck!
【小题1】­­_______is mentioned in the oldest good luck tradition.

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.
【小题1】From the passage, we learn that smog was a big problem in ______ in London.
