PART 2
However, plausible as the above scenario may seem, it is still irrational to overstate its significance because sometimes it is no use to be polite being polite utterly fails to solve problems, especially when we focus on in the case of emergencies. For example, you should not count on expect policeman be polite to the criminals who no comma are threatening others' lives. "Count on him" means "trust him". We usually use "count on" for good things. 如： "You can count on him to do the honorable thing". When people's lives are under threatened, “under threat”="threatened", but "under threatened" is not something we say the best way to solve this the problem is not by being polite to criminals. The only thing we should do is forcing use force to subdue them, thus ensuring others’ lives and safety. It is these impolite measures that are useful to deal in dealing with emergencies sometimes.
Very well done! Talk to you tomorrow.

PART 1
Should we always be polite to others?
There is no denying that always being polite to others is very important an important way for us to get on well with others them and thus helping helps us deal with trouble, especially when we refer to trouble in our daily lives. OR: ...is very important when we are trying to get on well with them.... Always being polite will make others easy to accept you and your opinion more easily. This point is much crucial is a crucial point for teachers trying to correct students' problems. One illustrative example being is my brother Jim, he who is a math teacher in high school. Every independent clause (分句) needs a conjugated verb. "being" is not conjugated. We use "an example being" for subordinate clauses, 如：“Some dogs are mean, an example being my neighbor's poodle, which bites me every time it sees me.” So polite he is He is so polite that everyone who knows him likes him very much. The word-order you used is only used in poetry and very, very formal speech. He is also so very polite to his students; every time his students make any mistakes, he will talk talks with them patiently. And it is really useful for students to students benefit greatly when they accept his advices. "Advice" is non-count, like water or sand. From this point of view, if you want to make others agree with you on your opinion, it is better for you to be polite to others.
