Answer 1

1. 问题的关键提示在anymore，不再。
完成时是表示过去一段时间开始到现在，而“不再”表示的是将来的意思。只能选进行时。而且如果是haven't\hadn't的话，应该说，haven't\hadn't talked to each other for a while...应该是for a while,for a long time这样的话一起用。
2. 这个题目可以从意思来理解。想象一下当时的情景：有报道说，一列火车在伯明翰附近发生撞击事故。根据目击者的描述，火车当时撞向一个放在铁路线上的水泥柱。
hit是事故发生当时的事情，而把水泥柱放在铁路线这个动作发生在什么时候呢？不可能是事故同时发生，所以不能用一个时态，而是事故发生之前，有人放在铁路线上的，所以用过去完成时。
3. were left，表示被动地处于一个状态，而不是他们自己想要被倒挂在过山车上。were leaving就是一个leave的普通动词的意思，离开，与题目意思不符。
4. 咖啡价格下降，所以我买了三罐......
