Ten years ago, there were many narrow streets.But now many streets have been widened. So buses and cars can go more quickly 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 dont have to worry about going out. With the development of science and technology, the transportation in Shanghai will become all the better.

十年前，有许多狭窄的街道，但是现在许多街道已经被拓宽。因此，客车和轿车可以开的比以前更快。十年前，从城市的南向北走是很不方便的。但现在，在不到一个小时的时间里你可以去到任何地方。我们高兴地看到，我们有两个地铁线，而且还有更多正在建设。我们很少看到在高峰时段交通堵塞。所以我们不必担心走出去。随着科学技术的发展，上海的交通会变得越来越好。
