they were talking about the rising unemployment rate___ a cup of tea at lunchtime yesterday.
A during B over C within D in 为什么是B,ACD错在哪里?还有一题It's not certain how the fire started last night,but it ____ by electrical fault.A might start B might have been started C may be started D must have been started 为什么是B,不是选A ,start 好像是不及物动词,应该没有被动语态吧?而且by electrical fault 不是说明一种客观事实吗?

They were talking about the rising unemployment rate___ a cup of tea at lunchtime yesterday.
A during B over C within D in
选B.
这里的over意思是：while doing,having,eating,etc (sth); during 在...期间:
其它选项没有此意.
又如：
1.Let's discuss it over lunch 吃午饭时商议此事
2.He went to sleep over his work.他干着干着活儿就睡着了.
3.We had a pleasant chat over a cup of tea.我们一边喝茶一边愉快地聊天.
It's not certain how the fire started last night,but it ____ by electrical fault.
A might start B might have been started C may be started D must have been started
选B,
根据It's not certain how the fire started last night昨晚发生火灾不确定因素,might的可能性最小.
might+完成式 表示对过去事情的推测(last night).start 可以是及物动词,有被动语态.这里的by electrical fault 是说明了一种客观事实,也是“执行者”.
might+一般式 表对现在的推测.
