作文的話，在這塊可以給你講一點技巧，主要是同義轉化的方法，可以提高一下作文的level~

1、寫長句。可以在任何句子之間加and, 但最好是前後的句子又先後關係或者並列關係。比如說： I enjor music and he is fond of playing guitar. 如果是二者並列的，我們可以用一個超級句式： Not only the fur coat is soft, but it is also warm. 其它的短語可以用： besides, furthermore, likewise, moreover .

2、轉折。很多時候我們的語言習慣會先說一些原因，然後將重點放在後面，也就是“but”後面才是我們要講的重點。比如說“he coat was thin, but it was warm.” “but”的同義轉化： despite that, still, however, nevertheless, in spite of, despite, notwithstanding .

3、因果。講道理的時候我們“so”，或者“because”，其也就是表示的是一個先後或因果關係! 比如說“The snow began to fall, so we went home.”更多同義轉化： then, therefore, consequently, accordingly, hence, as a result, for this reason, so that .

4、排比(排山倒海句)，當然這是寫作中比較高階的句式了，一個個的不定式，一個個地詞，一個個的短語的表達將會使文章很有氣勢和“level”的有沒有！看一下這個例句：

Whether your tastes are modern or traditional, sophisticated or simple, there is plenty in London for you. Nowadays, energy can be obtained through various sources such as oil, coal, natural gas, solar heat, the wind and ocean tides. We have got to study hard, to enlarge our scope of knowledge, to realize our potentials and to pay for our life.

其實，用一本適合自己的教輔書往往會有事半功倍的效果。在學姐的種草下選了巨微英語的《六級真題逐句精解》，剛開始不以為然，用了以後才發現這書挺好的，專門針對我這種基礎不是逆天，又有點懶惰的人，一個詞一個詞、一個句子一個句子的講解，重點語句圖文精解，省了查詞彙的時間，直接提高複習的效率，詞彙語法一次就吃透了！
