关于第三题，记得白勇里面貌似有提过书面语中There be sth done永远错,不过不敢保证记忆100%可靠>_<
第五题貌似是个节目预告/简介,客观的表述将来会上演的节目流程而已，用will

1 it指代n，不可以指代动作，c中do指代used mud and grass to build their homes这个动作。
2 Determined表示被动所以用过去式，differing表示一般现在时。
3 A中的caused by没有体现出原句的因果关系，
4 Such as表举例。
5 over more than 50 years表示要用一般将来时。
6 D中的these speculators had to sell与后句的their selling pushed other investors to the brink逻辑不通。 those who bad bought on margin没有从句简洁。
7 Seeming to be修饰Hosae Hudson逻辑不通。
不是牛，大家共同探讨

谢谢~ 除了第3个都理解了
我觉得caused by就是有什么引起的 也有因果关系啊
谢谢~

2. ABC 修饰的对象不对，which 这样只能修饰the abolition of local times
而题目的意思 是修饰 The growth of the railroads
按照这样的理解 determined differing 的逻辑关系 很容易看出E 才是正确答案！

1 B 是肯定不对的，有两个动词了，而且没有and 表明是两句话
至于D 那个making do without 我也不知道，但是可以用排除法，
A 错在it 没有指代，C太冗杂，E 的话 被动形式不好。。

谢谢 指点~~~居然没看出来谓语动词错误。。。
