學會這三點，寫作高分不再難

The most important rule to writing effectively is to not rePEat yourself. Each of these three rules focuses on avoiding repetition in English.
寫作最重要的原則就是不要重複。下面這三點能夠教你有效避免重複：

RULE 1: DON'T REPEAT THE SAME WORD
一、不要重複同一個單詞

One of the most important rules in writing English is to avoid repetition. In other words, don't use the same words over and over again. Use synonyms, phrases with a similar meaning, and so on to 'spice up' your writing stile.
英語寫作最忌重複。不要翻來覆去地重複一個單詞。可以使用同義詞、近義短語等，來調節你的寫作風格。

RULE 2: DON'T REPEAT THE SAME SENTENCE STYLE
二、不要重複相同的句式

In a similar way, using the same sentence structure by repeating the same structure over and over again is also considered bad 's important to know a variety of ways to make the same statement.
句子結構上的單調重複也容易造成寫作失分。因此，平時有必要積累相同內容的多樣化表達。

Here's a quick review of these forms:
Coordinating Conjunctions
比如使用並列連接詞，but, so，for等等。

Subordinating Conjunctions
比如使用邏輯聯結詞引導一個從句，though等等。

Conjunctive Adverbs
句間副詞短語，如as a result,however,otherwise等等。
Prepositions
介詞短語。

RULE 3: VARY SEQUENCING AND LINKING LANGUAGE
三、連接詞多樣化

Finally, when writing longer passages you'll be using linking wordsand sequencing to connect your ideas. As in word choice and sentence style, it's important to vary the linking language you use.
組織比較長的段落的時候，使用連接詞、順序詞組織觀點。在遣詞造句上，儘可能使連接詞多樣化。
舉個例子：

Instead of writing:
First, open the box. Next, take out the equipment. Next, insert the batteries. Next, turn the device on and begin work.
You could write:
First, open the box. Next, take out the equipment. After that, insert the batteries. Finally, turn the device on and begin work.
