The skyscrapers

This Monday we started a new unit which named is The Skyscrapers~~This is my frist time to learn sth and try to found new things about the skyscrapers~!

Nowadays, the skyscrapers are more common than before. We could find it everywhere, especialy some big cities like Hong Kong, Beijing, Tokyo, New York.........
Do you know why people want to build the skyscrapers? Before I leart it, I just know the simple reason that everyone could know is saving space for the city.Actully, that is the truth, and also it's the main reason that why designers and engineers try to build them. For example, many big city don't have enough land for the growing population. The only way they could go is "up"~! Moreover, there are many other reasons for creating the sky city.
People think the skyscrapers could save the time for people's daily life. Tokyo is very big crowd city. Eventhough they have very good train station system, the city is too big to let people move fast.People have to spend a lot of time on transportation. They think if the could work and live in the skyscrapers, it's really good for them to save the time~!
Of course people have other reasons such as solve urban sprawl for the rapid growing population in big cities, save energy, improve the development of the economic in the cities.........
However, the designers and engineers of the skyscrapers have to face many problems, like how to prevent the damage of skyscreapers from the cases of fires, the earthquakes, and the powerful wind and so on........Eventhough we have high-technologies....designeers cann't 100% to fix all problem in the hurry......therefore, many people against to build the skyscrapers....

In my opinion, I think creating the skyscrapers is a good idea. It can let people have better life, save land, save time and so on. I think we could fix those problem with the new techonogies in the future.
