People judge others by what they say and what they do. How you speak to others also contributes to the impression you make. Whether communicating with colleagues and superiors (上级) or family and friends, it's beneficial to speak to people politely. __36__ It makes them more willing to accept what you are saying.
__37__ For example，“Please close the window” or “Close the window, please” is much more polite than “Close the window”.
Use helping words such as “would”， “could”， “will” and “can” to soften a possible demanding meaning when you want something done. Giving commands as questions makes them more polite. __38__ 
Use a soft tone (语气) when speaking politely. Tone can change the meaning of your words from politeness to anger. __39__ For example, if you say “I do not want to go” with a stress on the word “not” or “I” and anger in your body language, you will sound less polite than if you keep the tone calm.
Be aware of how loudly you are speaking. __40__ For example, “I do not want to go” when stated in a low, quiet voice is more likely to be understood as a polite request, than if the same statement is said loudly, like a demand.
