Answer 1

1 spend话费 charge索费，是收取费用，根据意思
2 这里边是充当宾语，a选项只能充当状语
3 前面说现在不抽烟了，那么抽烟有十年是过去的事情，与现在无关，所以用过去时
4 only to do表示意料之外的结果，这里用stopping现在分词表示伴随状语。only只是修饰。
5 he had left hanging over the seat 是定语从句，the bag在从句中充当left后面的宾语。这里是leave的复合结构，leave the bag hanging这里是让包挂在座位上，表示的是状态。而hung虽然表示被挂，但表示的是动作。而Leave这词就是解释为“使---处于---状态”

Answer 2

1.如果在公共交通上的收费能更合理，大众们能轻松一些。这里指政府向群众收取的费用
.2.after 介词+名词/doing
3.个人认为是答案错了，因为for后是一段时间，显然前面动词应为延续性，应该是have ever smoked
4.only to do表出乎意料的如：i got there only to find the tickets have been sold out
此题可不看only ，stopping是现在分词，是非谓语，用doing形式
5.hang有两种意思，当指用绞刑绞死是过去分词是hung，hanging表示挂着的状态，作形容词
