1.What does this mean? "opportunities are generally chances to accomplish something positive-- I want to suggest that 'opportunity' is a more affirmative word, while 'chance' is more neutral. This is my opinion.
2.Does 'take an opportunity' express less enthusiastic than 'seize an opportunity' and more passive?-- I would say less enthusiasm but no passivity.
3.You should take/seize the chance/opportunity to travel while you're still young." Does 'seize' also work here? --Yes
What is the subtle difference between 'chance' and 'opportunity' here?-- As above
4.."I'd like to take/seize this chance to thank you for all your hard work." Does 'seize' work here?-- Yes, but 'chance' is not so good, as I explained in an earlier post.
