we should not expect people to be polite to each other.

[Chris Shi]

I am always amazed when I hear someone saying that we do not need to expect people to be polite to others as the world is busy and crowded. Even if one does not know the concrete examples that politeness is always important and necessary, one could deduce it from general principles.

To begin with, in modern society, with the high-speed development of economy, the life path is also speeding up. Under this circumstance people become busy and rush, they endure strong burden from everyday's hard work. But at the same time people from all over the world communicate with each other become increasingly frequently. To be polite to others can make communication easier. A smile can always make you feel warm despite your country, age, education background and so on. Politeness represents one's quality especially for the ones who accept higher education such as graduate students of university. If a graduate student has a rough manner, even if he or she has high scores in university, he or she cannot succeed.

Furthermore, politeness is an ancient tradition in China. As an ancient civilized country, many Chinese traditions including politeness have been passed down from one generation to another. Although now is the new century, the good manner is always proper and beneficial. For example, there is an old story in China that a very respectful young man named Yangshi. One day he went to a famous master-Chenyi's home to ask questions. When he arrived, Chenyi was taking a nap. So he waited outside the door to avoid disturbing the master even it was snowing. The snow was becoming heavily but he insisted waiting until Chengyi woke up. The story shows Chinese tradition of reverence for the teacher and elders. In 21th century it is still important that honor the teacher and respect his or her teachings. So, politeness is not only a tradition but also a requirement to realizing a harmonious society today.

In conclusion, despite the heavy competition today, we should still expect people to be polite so that individuals and society can be benefited as a whole.

Hi Chris, welcome to the forums.

You write well, with good spelling and punctuation. Your essay is well structured, though general advice is that you should try to include at least 3 main points, not just two.
There is evidence of wrong word choices/endings and missing articles which you need to be attentive of, for example:

To begin with, in modern society, with the high-speed development of THE economy, the life path WAY OF LIFE is also speeding up. Under thESE circumstanceS people become busy and rush, they endure strong burdenS from everyday's hard work EVERY DAY. But at the same time people from all over the world communicate with each other become increasingly frequently WITH INCREASING FREQUENCY. To be polite to others can make communication easier. A smile can always make you feel warm despite your country, age, educationAL background and so on. Politeness represents one's quality especially for the ones THOSE who accept ENTER higher education such as graduate students of universitIES. If a graduate student has a rough manner, even if he or she has high scores in university, he or she cannot succeed.

Sorry about the capital letters - it's the quickest, easiest way of highlighting changes.
A couple of points to note from that paragraph:

Don't start sentences with 'but', 'and', etc in formal essays. You may lose marks. Google the difference between connectives and conjunctions to see which words you should/shouldn't use.

Every day (a two word expression) means daily/each day.
Everyday ( a one word expression) actually just means ordinary or commonplace.
Although both would make sense in your essay, your phrase as you wrote it sounded odd.
