本次翻译难度较低，处理方式在上课时均有讲解：

本篇涉及到的词汇难度不高，“地铁”选用subway, underground, metro可以凭借个人喜好，交通拥堵比较正式的说法是traffic congestion, 不过使用traffic jam也是可行的。

选词方面，原文出现了两次“越来越多”这个短语，除了最为常见的“more and more”这个表达外，“a growing number of”也可作为一个选择，增加用词的多样性。

有一个句子需要特别注意，“在有些城市里，乘客只需用卡或手机就可以乘坐地铁”很多考生看到“只（需）”很快就会联想到only，然而这里表达为“passengers can only use cards or cellphone…”是错误的，乘客并非“只能”使用“卡或手机”才能乘坐地铁。恰当的选词是“just”，此外，短语“as long as”也不失为一个可行选择。

总之，只要课上所讲到的技巧大家都熟练掌握了，翻译部分得到12分左右应该是完全没有问题的。
