The positive influence of internet on our life.
My name is Zhu Zhenfei, and I speak on behalf of those who support the Internet. In other words, I believe that the Internet has had a positive impact on our lives. Any analysis of the Internet and its application must include the following two points: first, the value of the Internet to people who search for information; The second is that the Internet has given us the ability to organize teams and build friendships online.
Nowadays, when people need information, whether it is current news, weather forecast, travel routes or academic research, the Internet is the first choice for many people. With the click of a keyboard or mouse, students can gain knowledge from the world's largest libraries and museums, whether they live in small villages or downtown areas of big cities. Internet enables people to discuss any topic with experts, and also enables people to read articles written by leading figures in various fields.
But at the same time, some people are skeptical. They think the Internet is useless and it is a waste of time to use it. They say that children spend a lot of time chatting or playing games instead of concentrating on their studies. However, according to a recent survey in the United States, 80% of people who regularly use the Internet go online mainly to find answers to questions. 79% of the respondents believe that the second largest use of the Internet is to increase knowledge about hobbies. These figures prove that obtaining information is the main purpose of people using the Internet.
Another wonderful thing about the Internet is that people establish social connections through it. One of the greatest benefits of online friendship is that it is based on common interests, not on people's appearance, age or popularity. Young people from different countries and backgrounds have found lifelong friendship on the Internet. And those disabled people who have to stay at home can also communicate with the outside world through the internet and meet people with the same hobbies. Without the internet, these people wouldn't have so many opportunities to communicate with others.
In a word, I believe that the Internet is a useful tool that can make our life better.
The negative impact of the Internet on our lives.
My name is Lin Lei. I speak on behalf of the other party. I think the Internet has had a negative impact on our lives. As far as its shortcomings are concerned, I want to mainly talk about the lack of monitoring information and the change in the way people use time.
Of course, it is very important for researchers to get the latest and accurate information. One of the greatest benefits of the Internet is that it can provide such information. But its disadvantage is that it is difficult for people to judge whether this information is true and accurate. False information on the Internet is becoming a thorny issue day by day, because people can write at will, but we can't always tell whether the information is true or false. In 2003, Yi Bei, a famous e-commerce website, pointed out that 70% of the troubles were caused by those who sold things that didn't exist or made false propaganda about the products they sold. University professors all over the world are complaining that their students use false information found on the Internet in their papers submitted to them. If people use traditional methods, such as looking up information from books, newspapers and magazines, these problems caused by inaccurate information will not appear so frequently.
Another disadvantage of the Internet is that it affects people's private lives. With the popularity of the Internet, the way people use their time has also changed. Nowadays, some family members don't get together at night, but do their own things: some people are playing computer games, while others are staying in internet cafes. In fact, some young people spend a lot of time playing computer games and surfing the Internet. As a result, they become more and more addicted. In order to solve this problem, Beijing set up an outpatient clinic in 2005 to treat Internet addiction patients.
Some experts say that spending a lot of time building online relationships will only damage people's ability to lead a normal life. A university has made a survey of students who stopped studying before graduation, and found that 43% people are obsessed with computers. This study clearly shows that people who surf the Internet all day will feel disconnected from the people around them and the world.
These are some negative effects of the Internet on our lives. In my opinion, it is still very important to restrict the use of the Internet, or to deal with the problems brought by the Internet.
Unit 4 The first subway in the world
Welcome to the London Underground-it's also called the Underground. The London Underground enjoys a long reputation because it is the oldest and most complicated subway system in the world. In the first half of the19th century, the train service to London was ancient. But most trains to London only go to the outer suburbs of London, because building a railway in Picard will destroy many ancient buildings. This requires a large number of buses to transport people to the city center. Unfortunately, it seems that the road is blocked by more cars, and the traffic has become so congested that everyone can't move. In this way, traffic problems have formed an opportunity for subway development.
1854, Metropolitan Railway Company was authorized to build an underground railway between Paddington and Farrington. It became a fast-track between King's Cross Railway Station, St Pancris, euston, Paddington and central London. The first subway tunnels were opened at 1863, which are very close to the ground. Passengers take a windowless train, which is driven by a steam engine and shuttles through a relatively narrow tunnel. Can you imagine the smoke and noise? 1968 another part of the subway system was opened and operated in south London by a company called Metropolitan Railway. After 16, 1884, Metro Company contacted Metro Company to provide subway service for the downtown area. This line later became a cycle.
With the development of tunneling methods, the first subway tunnel crossing the Thames was completed in 1884. These new tunnel excavation methods have accelerated the development of London Underground. The 65438+ London City Line and South London Railway Line were connected with the rest of London in the 1980s. In the next 25 years, six independent deep subway lines were built. Then it is not convenient to walk these lines, because each line is its own master, and many lines are far apart.
Seeing this situation means that Charles yerkes, a wealthy American businessman, tried his best to improve the subway system by buying a number of different subway lines and establishing a subway group. After the acquisition, he gave each line a name, and many names are still in use today. 1933 established an organization called London Passenger Transport Department. The subway group, the metropolitan branch line and all bus and train lines are under the control of this department. This institution eventually became transport for london. Between 19 18 and 1938, with the establishment of many new subway intersections and the completion of new railway stations, the London subway has been greatly expanded. An architect named Charles holden designed many new railway stations, which are still in use today.
During World War II, London was bombed and many subway stations became bomb shelters. A new subway line is used as an underground plane factory, a closed subway station is used as an anti-air raid center, and the station closest to the Prime Minister's residence is used as a government administrative meeting room by the Prime Minister. Therefore, the subway system played a special role during World War II.
1945 After World War II, more people took the subway, so more subway lines were built. Almost all stations, including the Victoria Line, are connected with other lines. This makes the subway system more convenient for passengers. The last new line, the Jubilee Line, was built to commemorate the 25th anniversary of Queen Elizabeth's accession to the throne. 1977.
The London Underground successfully transports millions of passengers every year and has been doing so for many years. 3 million people take the subway every day. The whole subway network includes 12 lines, and now the subway has extended to an area 26 miles away from the center of London. So why not take the world's oldest subway for sightseeing today? Come on, buy a travel card at our ticket office, and you can enjoy the whole subway system.
