我们一直跟大家强调英文写作一定要简洁，简洁才有力度。但是大家会觉得矛盾的问题在于很多论文作业都是有字数要求的，几百字到几万字不等，如果要尽量把文章精简是否会影响到文章字数呢？很多留学生在英文论文写作的时候都会有这样的问题：字数够了但是文章不够精简，或者文章足够精简但是字数却未能达到要求。想要解决这个问题需要大家对自己的论文题目有足够深刻的理解，论点论据都要做到有理有据等等多方面的因素，这些我们暂且不谈，我们今天用实例来为大家分析下在英文论文写作中如何去掉多余的单词实现简洁。Write concisely so that your writing is vigorous.
上面这句话表达得不够简洁，原作者是这样说的：Vigorous writing is concise.
A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, (第二个动词都省了，够简洁！)
for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. (第二个动词都省了，够简洁！)
This requires not that the writer make all sentences short, or avoid all detail and treat subjects only in outline, but that every word tell.
如果提出了这个问题说明语法学得不错，但是。。。没学到家。这里实际上是requires sb (should) do 的形式，这个should可以省略，类似的动词有：suggest, order, require, propose, demand, request, insist。
the question as to whether
whether (the question whether)
there is no doubt but that
no doubt (doubtless)
used for fuel purposes
used for fuel
he is a man who
in a hasty manner
this is a subject that
Her story is a strange one.
Her story is strange.
the reason why is that
“The fact that”是常见的多余表达，应该从句子里剔除掉！
owing to the fact that
in spite of the fact that
call your attention to the fact that
remind you (notify you)
I was unaware of the fact that
I was unaware that (did not know)
the fact that he had not succeeded
the fact that I had arrived
Case, character, nature, who is, which was等表达也常常是多余的：
In many cases, the rooms lacked air conditioning.
Many of the rooms lacked air conditioning.
It has rarely been the case that any mistake has been made.
Few mistakes have been made.
acts of a hostile character
acts of a hostile nature
His cousin, who is a member of the same firm
His cousin, a member of the same firm
Trafalgar, which was Nelson's last battle
Trafalgar, Nelson's last battle
The active voice is more concise than the passive, and a positive statement more concise than a negative one.
A common way to fall into wordiness is to present a single complex idea, step by step, in a series of sentences that might to advantage be combined into one.
Macbeth was very ambitious. This led him to wish to become king of Scotland. The witches told him that this wish of his would come true. The king of Scotland at this time was Duncan. Encouraged by his wife, Macbeth murdered Duncan. He was thus enabled to succeed Duncan as king. (51 words)
Encouraged by his wife, Macbeth achieved his ambition and realized the prediction of the witches by murdering Duncan and becoming king of Scotland in his place. (26 words)
