飞天傻兔

In the 1820’s, anthracite coalfields opened in eastern Pennsylvania, and when canals and eventually railroads reached into the region, there were substantial supplies of coal that was exported to the nation’s growing mills, forges, factories, and railways.

A.        when canals and eventually railroads reached into the region, there were substantial supplies of coal that was
B.        once canals and eventually railroads reaching into the region, there were substantial supplies of coal having been
C.        with canals and eventually railroads reaching into the region, there had been substantial supplies of coal
D.        canals and eventually railroads reached into the region, with substantial supplies of coal being
E.        as canals and eventually railroads reached into the region, substantial supplies of coal were

题目如上，正答是E。

单纯做这道题我都理解，但是不明白划线句里eventually的修饰> <
副词放在名词前面不会很怪吗？

错选了D 现在想通了
还是要从句意出发：这题想表达的一个重点是，随着交通条件改善，煤被运往了全国各地。这是一个先行后续的过程，改变这点的选项就不行了。

A and when，when没有平行对象，there be 错误暗示： 有运河跟火车的时候，煤就开始运了
B once表示的一种假设，但这里是历史，无须只有的语气。
C with 暗示2件事情同时发生
D 同上

E里 as很好滴表达了 随着某事发生，另外一件事件也跟着发生的情景。

个人觉得选项不是when as的区别；主要是事件发生的时间顺序；
A.        when canals and eventually railroads reached into the region, there were substantial supplies of coal that was
B.        once canals and eventually railroads reaching into the region, there were substantial supplies of coal having been exported发生在 railroads之前
C.        with canals and eventually railroads reaching into the region, there had been substantial supplies of coal with表伴随同时发生 与后面时态矛盾
D.        canals and eventually railroads reached into the region, with substantial supplies of coal being
E.        ！as canals and eventually railroads reached into the region, substantial supplies of coal were
AE的话 应该是substantial supplies of coal的限定于非限定修饰问题吧！

呵呵，共同进步
以前我也不会多看A只是觉的它别扭就完了。when肯定是错的不管它there be了就
但是最近看 ...

请教下，我还是不怎么明白A中when为什么一定错。

这有个when，while，as的区别说明,怎么觉得when在这里也说得通呢？毕竟reach和were都是延续性动词，were可以表一个状态啊

好吧，我也找不出什么理由反驳你了> <

那你觉得把下面这句话里的when充当的的角色放到E里可行么？

when强调主从句中的动作有先后，as表伴随，动作往往是同时发生的。所以你的例句里不能换成as，因为locust不能一边被place，一边表现出excited等

但是最近看到了中学学的语法，发现了这么一个知识点。 可能there be 在A中确实不如E的表达要好。就像主动可以转化为被动但是特定句子中还是要用某一形式。但是总之我认为我们能在更深一个层次去论论它的错误了，这样可能会发现一些更关键的东西，至少为能够这样做做了一些准备

这里的when是一旦的意思，当然不能放到E中

好吧，虽然我可能还需要一些时间才能想明白><总之谢谢讨论

我认为换成when就错了，可以换成after

GWD28-Q21: According to entomologists, single locusts are quiet creatures, but when locusts are placed with others of their species, they become excited, change color, vibrate, and even hum.

我同意你的观点，when和as表达的含义不同

可是万一作者本来就想说在运河铁路通了的时候呢？额这样问可能 ...

我认为换成when就错了，可以换成after。
只所以我认为there be 没有错，是因为当初在中学的时候学习句型之间的变换E的表达方法和A是完全可以相互变化的。尽管不能说句型的变化以后意思完全相同。这里E的表达方法也确实比A要好，但是比起你说when在E中也勉强可以算对，我认为A中的there be并不是关键的错误
