It’s not that hard to be a better writer. Seriously, it’s especially true if you’re starting as a non-writer who’s just trying to be competent for day-to-day tasks.

1.Have a Structure.   1   Your body should consist of paragraphs that are grouped according, to topic, each one dealing with a single element of your subject.

2.  2  When you say a car runs "fast" , don't leave it at that.Show me how fast it is by ; detailing the vehicle' s top speed and acceleration, along with listing other cars it leaves in the dust.Do the same with every other significant modifier(修饰语) you use.

3.Don't pad words.  3  Most of the time, this ends up turning what' s essentially nice; writing into unreadable nonsense.You' 11 see this with heavy use of unnecessary adjectives and adverbs, along with useless phrases that can easily be cut off without losing meaning.

4.Choose good words.Sometimes, the way your text reads comes down to word choice.Don't say " converse" when you can say " speak" ; don' t write " adjudicate" when you say "decide".  4 

5.Use a writing software.Notice that we didn't give any advice on grammar.That's because using a quality proofreading software can help you on that end.  5 

A.Try not to use adjectives and adverbs without providing an explanation.
