Answer 1

1.B.原因:逗号后是句子，而A.C.D都是句子，逗号不能连接两个句子。B项 是with的复合结构，在这里作时间状语。句意为：火车开车前五分钟，我们到了车站。
2.D。原因：考查现在分词作定语。这是个倒装句，正常句序是One...was among the laws....在美国建国最初的200年中，通过了一项法律，规定学校周围300米内持枪是违法的。one指的是one law,法律规定是主动动作。所以用ing形式。
3.C. 原因：guidance是不可数名词。只有a good amount of修饰不可数名词。A.B修饰可数名词，VERY MUCH只能修饰动词。
4.A. 原因：in any case无论如何，somehow不知怎么的，以某种方式 to a great extent很大程度上，in case，以防万一,单独用常放在句末。句意是：我们不可能知道他们想做什么，无论如何，必须做好准备迎接强烈攻击。
5.C. 原因：such修饰名词English，另外as引导定语从句，要做成分。作understand的宾语。
