各位好，想请教一下
外国网友Raymott回应我的问题 https://goo.gl/Ai5B2H
但有些我看不太懂：
I was intending to give you the idea that by 'not' writing,
→什么是'by "not" writing'？
"If someone talks about an idea, should we say (a) or (b)?" you are answering
your own question.
→为何他会说“你正在回答你的自己问题”？
In the context, you are asking whether "mention" is a verb similar to "like,
wish, etc". No, it isn't. If you are commenting on what someone is doing now,
you would say, "He is mentioning it now."
→他的意思是说，照我后来补充的情境来看，mention在那个情境中并不是静态动词，所
以可以进行式来表达？
But you haven't given a proper context, so others have replied, just as
validly perhaps, that you could say "He mentions it now". 'Mention' is not a
stative verb.
→他的意思是说，如果没有给出适当的情境，"He mentions it now"也有可能是正确的？
但他后面又补充一句'Mention' is not a stative verb. 是想表达什么？
请教一下，谢谢！
