Great changes have taken place in Shanghai's transportation.Ten years ago, there were many narrow streets.
But now many streets have been widened. So buses and cars an go more uickly than before. Ten years ago.
it was not convenient to go from the north of the city to the south.
But now, you are sure to reach anywhere in less than an hour.
To our joy, We have two underground lines and many more are being built.
We seldom find traffic jam in rush hours. so we don't have to worry about going out.
With the development of science and technology, the transportation in Shanghai will become all the better.
过去十年上海交通发生了很大的变化，以前都是一些狭窄的道路，现在很多道理都是非常宽广，公共汽车和小汽车也比一起跑的快，
十年前，从城市的北方到南方是非常不方便的，但是现在，你能到达任何角落在不到一个小时时间内.
使我们高兴的是，现在有两条地铁线，而且更多的地铁线将会被建立.
在高峰期，很少发现交通拥堵，因此，我们不必担心外出，
伴随科学和技术的发展，上海的交通将会变得更好.
