Cut out words, phrases, and sentences that don't add any information or serve a purpose. Watch out for repetitive phrases such as "refer back" or "serious crisis." Don't use conjunctions to join sentences that would be more effective as separate sentences.
Be forceful.
Avoid jargon and pompous language; it won't impress anybody. For example, "a waste of time and money" is better than "a pointless expenditure of temporal and financial resources." Avoid cliches (陈词滥调) and overused terms or phrases (for example, "beyond the shadow of a doubt"). Don't be vague. Avoid generalizations and abstractions when more specific words would be clearer. Don't use weak sentence openings. Be wary of sentances that begin with "there is" or "there are." For example, "there are likely to be ways to improve those sentences," is much weaker than "You can probably improve the sentences." Don't refer to yourself needlessly. Avoid pointless phrases like "in my personal opinion." Don't be monotonous: Vary sentence length and style. Use transitions to connect sentences and make your essay easy to follow.
