safety 是名词.safe 是形容词 (当名词用的时候不是安全的意思,是保险箱的意思).
楼主第1句:It's () 是歧义的,两种解释如下:
1a) It's safe.这/它是安全的.如:Is it safe to eat raw lettuce?Yes,it is safe.
1b) It's safety.如:"Why do I have to put on my helmet?" "It's safety first." 为什么我要戴头盔呢?安全第一.
其实,1a) 比 1b)常用多了.
后面:It's a safe place.这里需要形容词修饰后面名词 place,所以选safe
The place is safe.这里要形容词做is的标语,所以是safe.
清楚吗?
我有英语学习Q,楼主有可以加你.

safety 是名词
safe 是形容词
所以是it's safe

都用safe,因为safe是形容词,放在be动词后,名词之前
safety是名词

safety safe safe
