The London Olympic Games are coming soon. This summer, Chinese sports fans will be able to watch the exciting games in 3-D on CCTV.
When you watch 3-D movies or TV, you have to wear a special pair of glasses. The 3-D glasses make the people and the things on the screen look like they are in the room with you.
3-D, means having three *dimensions: *width, height and *depth. 3-D technology is based on the way the human brain and eye work. Because the *pupils of a person’s eyes are about 6.5cm apart, when we look at something, each eye sees it from different *angle. Our eyes send the two pictures to our brain, and the brain puts them together. The small difference between the picture from the right eye and the picture from the left eye make us see depth.
While watching 2-D films, we don’t have to wear the special glasses. We see the pictures in two dimensions, each eye get the same information. This is because there is only one way of watching it.
So the aim of 3-D technology is to get a different picture into each eye of the person. It uses two film *projectors. One *projects a left eye picture and the other projects a right eye picture. When we are in the cinema, we can see different pictures in each eye at the same time with the help of the 3-D glasses.
While watching 3-D films, we feel that we are actually in the same environment as the things we are watching. However, some people are against watching 3-D films. One of the reasons is the 3-D glasses makes the screen of the film or TV look darker. It is bad for eyes. What’s more, people with eye problems may get headaches if they spend too much time watching 3-D movies, because their brains need to work harder to “read” the pictures.

A.how we see things in 3-D B.how we watch the Olympic Games
C.how 3-D films are made D.where we watch 3-D films or TV
【小題2】When we watch a 2-D film, each of our eyes get ________ information.

As soon as you land at London Heathrow airport, you will see it is easy for you to ride the subway or take a bus to your hotel. However, if you are planning on touring London, it would be the best idea for you to rent a car so that you can go wherever you wish to visit freely and you don’t have to run to catch a bus or a train. Remember that the trains in London are always very crowded. So a rental car is the easiest and most comfortable way to travel.

London has so many different attractions(旅游景點(diǎn)) to offer and the same is true for England itself. In London you can find Buckingham Palace, which you can also visit during summer time when the Queen of England goes to one of the castles(城堡)around the country. If you are interested in history and art, you can’t miss the National Gallery, which is right in front of Trafalgar Square. Not far from Trafalgar Square, there is the House of Parliament that faces the Thames River. If you wish to have a good view of London, then the best idea would be to take a ride on the London Eye, the tallest Ferris wheel(摩天輪)of Europe. The tour takes about half an hour so you can sit comfortably and take pictures of London from above.

London is not too far from other major cities and attractions in England. For example, a drive of only one hour and a half will take you to Cambridge and with even less time than that you can reach Stonehenge to see the stones that have been there for centuries.

A.to take the subway                      B.to take buses

One thing that British and Chinese cultures share is a love for tea. Today, when we think of western tea culture, we often think of the English and beautiful china tea cups.

Afternoon tea:

People believe that an English lady, Anna, first introduced the idea of afternoon tea. In the 18th and 19th centuries, the English ate only two main meals each day, breakfast and a heavy supper that would last for several hours in the evening. As a result, people often got very hungry during the long wait between these two meals. To solve this problem, Anna came up with the clever idea of inviting some friends to join her for an afternoon meal between four and five o’clock. This meal included cakes, sandwiches, and tea was served to wash down the food. In order to make this afternoon meal important, fine china cups, plates, and silver teapots, knives, forks and spoons were used. Soon, afternoon tea parties became popular social occasions. Today, afternoon tea parties continue to play an important part in the social life in modern Britain.

Will you come for coffee:

Coffee also has an important role in British culture. People often use words “Will you come for coffee?” to mean “Would you like to come to my home for a chat?” Normally, several different drinks such as tea, hot chocolate or a soft drink like orange juice will be served as well as coffee, and you will be asked what you would like. However, you will not normally be offered wine at a “coffee” party.

Coffeehouses and the London Stock Exchange:

In the 17th century London coffeehouses were busy and noisy places. Businessmen and bankers went to coffeehouses to do their business, as well as to drink coffee. In fact, the London Stock Exchange(股票交易所)is believed to be started from these coffeehouses.
