Where he to leave today,he would get there by Friday.(If he left呢)
It is good to take a long walk before going to bed.(为什么ing这个时态)

答案

1 这个是虚拟语气倒装句 省略if的时候 就用倒装 were 在最前面
还原后是 If he were to leave today he would get there by Friday .
如果他今天离开的话 他将会在周五达到哪里
2 prefer doing to doing
而且rather than是宁愿...也不愿...而prefer to是喜欢...胜过...
表达的语气 情感不同
3 这里是虚拟语气主句与从句时态差别的问题 主句是would have done 现在完成时 相应的从句应该使用过去完成时
4 kept是keep的过去分词形式 前边有has所以是现在完成时 has kept
5 before是介词 介词后动词需变为ing形式
