Just look at the rain pouring down!
可以理解成：Justlookattherainwhoispouringdown吗？
还是理解成后置定语呢？
Seventimeshaveidespisedsoul.
为何这里have是倒装？
Just look at the rain pouring down! （正。目前分词作宾补）
Just look at the rain who is pouring down. （错。不要随意改动句子）
Seven times have I despised my soul. （倒装句，times 次数开头引出倒装）
Seventy times have I told you not to be late.
我不知告诉你过多少次不要迟到。
Many times have I heard this.
我听这话已经不少次了。
