1) What is the meaning of the nature of our times? The character of modern life.
2) I want to ask about commas in English. Are both sentences right:
If I had money, I would go to the US
If I had money I would go to the US
I wouldn't say a comma is mandatory, but I'd use one.
3) What is the true form of the verb contact:
I and my aunt contact (through/ by means of/ by) (email/ emails/emailing)?
It's a matter of what is idiomatic.
I and my aunt stay in touch . . .
I and my aunt contact each other . . .
Through / by means of / by are all acceptable.
Email is the most idiomatic choice of the three.
Best wishes, Clive
