在GRE寫作中單調的句式和結構、長度相近的句子使作文顯得呆板單調，缺乏生動性和說服力。而考生若想把作文寫得生動一些，就要學會豐富句子成分，使句子活起來!下面大家就隨小編一起去了解一下如何豐富GRE作文句子吧!
GRE長短句變換
也就是簡單句、並列句和複合句交替運用。長句準確生動，長於說明推理;短句簡潔明快，意義明確，印象深刻，描述動作，表明主旨，總結歸納，非短句不可。既然各有所長，在寫作時應根據實際需要，交替使用簡單句、並列句和複合句，以達到“段間長短不一，全篇句式萬千”、豐富多樣的效果，給讀者以及閱卷老師以永恆的新鮮感。
結構多樣化
我們學過非謂語動詞結構(包括不定式結構和分詞結構)，無動詞結構，分隔結構，比較結構，獨立結構，with複合結構，特殊否定結構，it結構，平行結構，強調結構，倒裝結構，等等。其中最爲神通廣大的是非謂語動詞結構，在句中或作主語、賓語，或作表語、賓語補足語，或作定語修飾名詞，或作狀語表示條件、原因、讓步、時間、方式、目的、結果、伴隨狀況等，不一而足。
