内个……方便的话、3、4、能不能翻译一下。谢谢啦~

1  在喝咖啡期间

2so far 用完成时，has.such提前引起全部倒装。

3that引导的是issue的同位语从句。意思是：一个主要的问题在会议上被一些代表提出，那个问题是在偏远地区的老师被少付工资。

4it  was  that  是强调句型，去掉it was that 句子还是完整的。前一个that 是定语从句。后一个和 it was 构成强调句。意思是：是传播了几乎整个国家的A/N1H1 传染病促进了研究和流感疫苗的产品。

over coffee 表示喝咖啡的功夫他们在闲聊，over a cup of tea是一杯茶的功夫

that the teachers in the remote areas were underpaid 是一个同位语从句，补充说明issue，表示。。。样的issue

前一个that是epidemic的定语从句，后一个是强调句的that
