口语单词练习（口语话题练习Traffic）

Q: What type of transportation do you use when you go to school? [Why?]

A: I frequently take the subway to school. When people are rushing to work and school, there is always heavy congestion on the roads. Cars hardly move so I cannot estimate the exact time when I'll be arriving at my school. Moreover, it is economical and convenient to take the subway since there is a subway station near my home and school, not to mention the subway train arrives every few minutes and on time.

我经常乘地铁上学。当人们赶着去上班和上学的时候，路上总是很拥挤。汽车几乎不动，所以我无法估计到学校的确切时间。而且，乘地铁既经济又方便，因为在我家和学校附近就有一个地铁站，而且地铁每隔几分钟就到，而且准时。
