Dear Mr Yeung,
I have some questions concerning English, and I hope that you can kindly answer them.
1.Which of the following sentences is correct?
a) The last date will be 29th June.
b) The last date will be on 29th June.
2. It seems that "pressure" and "stress" can be both referred to 壓力, but I think pressure is external, that is, when there is a lot of work or unexpected changes, the pressure is great. Stress is our internal feeling in reaction to pressure. Am I right? Or they are just the same?
3. In some legal documents, I often come across terms like "herein" and "hereby". What is the difference between there two words? It seems that they can be used interchangeably.
Thank you very much for your attention.
