答案

当以there,here,out ,in ,up ,down,away 等副词开头的句子,为了起到强调的作用,可构成倒装句,只把副词放在句首,主语和谓语位置调换,不加助动词.
Our teacher came in.
In came our teacher.
这种倒装要求：主语必须是名词.主语是人称代词时,主语和谓语语序不变.
Here it is.
上述题中,第1题和第3题都属于这一类.不同的是第1题中的主语I属于人称代词,所以主语和谓语语序不变.而第三题的主语a pretty girl 是名词,所以 主语和谓语位置调换.
so + 动词+主语 (对前面肯定意义的事情表示相同)
neither/ nor + 动词+主语 (对前面否定意义的事情表示相同)
表示两人的同样一个情况时,只能表示一件事,即上、下句所使用的动词、时态要一致.
否则要用so it is with…
You can ride a bike.So can I .你会骑自行车,我也会.
He has been to Beijing.So have I .他去过北京,我也去过.
The first one isn’t good,neither is the second.第一个不好,第二个也是（不好）.
His uncle is a worker and has been working in the factory for more than ten years.So it is with his aunt.他的叔叔是一个工人,已经在工厂工作十年多了.他的婶婶也是一个工人,已经在工厂工作十年多了
第2题 前面的Society has changed 是肯定意义,所以用"so + 动词+主语" 的结构；另外,前后两部分所使用的动词、时态要一致,前面是现在完成时态,所以后面也相应的用现在完成时态.
第四题属于 虚拟条件句的倒装
根据给出的句子的后半部分"they would certainly come and help us"和选项,我们可以推出,原句子是If they had time,they would certainly come and help us.
有些由if引导的条件状语从句（主要是包含有were,had,should的从句）,可以把if 省略,把上述动词放到主语前面去.
