Inventions
 


Phone
 

The first telephone was invented by Alexander Graham Bell in 1876. It made communications easier. But the telephones were only fixed in post offices. People had to go there to make calls to faraway people and the fees were very high. Later, a cellphone was developed in 1973 in America. It was one of the most useful inventions. People can use cellphones to communicate with others much more easily. They can take them anywhere to make private calls, even vision calls (可视电话). Cellphones have many other functions, such as sending messages, taking photos and reading online.
 


TV
 

The first TV set was invented by an English scientist, John Baird, in 1926. The invention helped people watch films at home instead of going to the cinema as before. At first, TV sets only broadcast black - white pictures. Several years later, colored TV sets made the pictures lively. However, they were heavy and thick, so it was difficult to move them. Then, digital TV sets came into being. They are light and thin. Many TV programs are available (可获得的) at any time. At present, people can use the IPTV( 网络电视) to record and replay programs.
 


Computer
 

The first modern computer was invented in America in 1946. It was as big as a room. It improved the speed and exactitude of calculation (计算). In the 1950s, desktop computers were invented in the same country. They became smaller and could be put on the desk. Since then, they have become very important in many fields of work and leisure. Before the 1970s, the computers were single. It was the Internet that joined the computers into a big family, so they could share information with one another. Around 1985, laptops were developedin Japan. They were much smaller and could be put on people's laps. They were light and easy to take.

Located in the southern part of the Yangtze River delta(三角洲),

Taihu Lake is the third largest fresh water lake in China. With a surface area of about 2,338 square kilometers, Taihu Lake is a famous scenic spot in China and is well known for its lake, its hills and its fantastic man- made scenery.

Taihu Lake is located in the Yangtze River delta. It crosses Jiangsu and Zhejiang provinces, where 48 islands, big or small, and 72 hills and peninsulas(半岛) along the lake combine to form a view of great natural beauty. The best place to view the beautiful Taihu Lake is on the Turtle Head Island. Turtle Head Island is an island whose shape is really like the head of a turtle sticking out from the water. Taihu Lake and the nearby scenery will attract you when you climb onto Turtle Head. When the soft winds blow, waves roll and the hills in the distance look like a landscape painting. The scene is really fascinating.

Besides the natural scenery of Taihu Lake, there are many historic sites , such as the Grand Canal (运河) of the Sui Dynasty, the islands in the lake along with the coastal places in the east, the north and the west, both of which are the cradle(摇篮) of the culture of Wuyue (this culture touches on traditions that flow from or refer to Jiangsu, Zhejiang and the southeast part of Anhui Province today) and so on.

Taihu Lake is a rich source of fish. Traveling there, you can taste the famous delicious food known as “Taihu Lake Three Whites”. They are white shrimp, white bait(银鱼) and white fish. The feast(盛宴) is generally prepared in the boat as one floats on the calm waters of Taihu Lake. It is very well worth a visit.
