请教大家AA028

28. The following appeared in the editorial section of a local newspaper.

“Commuter use of the new subway train is exceeding the transit company’s projections. However, commuter use of the shuttle buses that transport people to the subway stations is below the projected volume. If the transit company expects commuters to ride the shuttle buses to the subway rather than drive there, it must either reduce the shuttle bus fares or increase the price of parking at the subway stations.”

不知道大家AA28找的错误是什么，我看了范文的两点错误：

1 the author assumes that reducing shuttle fares and increasing parking fees are the only available solution to the problem

2 the author assumes that reducing shuttle fees and increasing parking fees are mutually exclusive alternatives.

我怎么看了半天觉得这两个错误跟一个错误差不多啊，请教大家都找出什么错误了，谢谢！

我也觉得没有其他的错误了，但是象下面这样写可能会好一点：

1.对原因估计的可能不对.由作者给出的他认为必须执行的解决方案来看,作者一定认为人们不坐往返巴士而是开车去地铁站的原因是巴士车费相对于地铁站的停车费来说比较贵.To begin with, by concluding that the transit company must either reduce shuttle fares or increase parking fees, the author assumes that these are the only available solutions to the problem of limited shuttle use.但事实原因可能还有很多.例如:巴士的环境不好速度比较慢中间间隔时间太长车站位置不好等等.
2.相应的作者所提出的两个必须要执行的解决方案也就不一定实用.应对于上述提到的问题可能一个比较好的解决方案是:对巴士进行装修把车站设置在更为便利的地方提高巴士的车速缩短时间间隔.

这题的确没有很多东西可写，要充字数有点难。谢谢！

谢谢，终于明白了些...

试找了三个原因，与大家讨论：

1、projection有可能本身不合理；

2、assume原因是因为人们drive不一定对，比如：有可能taxi什么的，drive 可能只占一小部分；

3、要么票降价，要么提高parking费没有考虑其他人们不坐shuttle的原因，如安全等。

刚刚练完这篇。我写的时候也写到这一点：the author assumes that driving and taking shuttes are the only available transportation methods for commuters to go to the subway. 但是现在回过头来想，作者究竟有没有作这样的假设呢？好象……是没有？

与大家讨论。

用must应该是有这样假设吧
