新托福寫作高分作文，往往句子表達豐富多樣，不是一種表達的重復堆砌，那么豐富多樣的托福作文句子怎么寫呢?小編為大家介紹幾種豐富句子的技巧，希望能提高大家的托福寫作技巧。
　　第一，使用不同的詞匯
　　a.使用同義詞
　　比如以下的一些寫作高頻詞匯的同義詞，你一定要掌握，出現的尤為頻繁。
　　important→essential, crucial, vital, significant,
　　think→claim, believe, consider, deem, figure out
　　nowadays→currently, at present, now, recently, in recent years, these days
　　b.改變詞性
　　這是一種稍微難一些的方法，要求你的語法基礎非常好，你才能靈活自如的運用。
　　n. → v.
　　Eg：When we look at a comparison between A and B…
　　When we compare A and B…
　　Adj. → n.
　　There are a variety of solutions to the problem.
　　There are various solutions to the problem.
　　c. 使用不同的承接詞。
　　承接詞在文章當中的使用相當頻繁，不僅是段落和段落的連接，還包括句子和句子的連接。背住一些常用的承接詞比你的改寫將會有極大的作用。
　　because of → due to, owing to, because, as, since, for
　　but → however, nevertheless, nonetheless, whereas
　　so → therefore, hence, thus, consequently
　　d.形容詞的逆向表達。
　　在某些形容詞上進行修改，會達到非比尋常的效果。
　　Eg: not as easy as…→more difficult than…
　　Not uncommon→common
　　The cheapest → the least expensive
　　第二，使用不同的句型
　　a. 改變詞序。
　　這是非常簡單的一種方法，完全不用動腦筋就可以進行改寫。常常將句子中的狀語(包括狀語從句)換位置。
　　Eg: For many years, people have believed ….
　　→People believed… for many years.
　　After this programs has been solved, work on … can continue.
　　b. 主動語態和被動語態的互相替換
　　Eg: Trained scientists performed this research.
　　→This research was performed by trained scientists.
　　c. 使用“there be” 句型
　　使用“there be” 句型，可以將一個簡單句，馬上變成一個加入定語從句或者分詞的復雜句。Eg: Several computer programs can be used to solve this problem.
　　→There are several computer programs that can be used to solve this problem.或There are several computer programs used to solve this problem.
　　d. 定語從句，分詞和插入語的互相替換
　　Eg: Study…, conducted by sociologists in 2004, shows that…
　　→Study…, which was conducted by sociologists in 2004, shows that…
　　Eg: This…, which is one of the most powerful … in the world, has…
　　→This…, one of the most powerful… in the world, has…
　　接下來，Cite，即引用。綜合寫作乃客觀寫作，只是一個旁觀者的角度對這兩篇文章的內容進行描述，因此，某觀點是出自哪篇文章一定要說清楚。所以，下面的這些句型在綜合寫作中必不可缺。
　　a.According to+noun.
　　Eg: According to the passage/lecture/author/professor,…
　　b.Subject+verbs of reporting +that clause
　　Eg: The author tells/reports/suggests/explains/says/argues/states/indicates/claims/points out/thinks/believes that…
　　或The speaker agrees/disagrees/rejects/disputes/challenges/takes a different view….
　　c. As is indicated/displayed/illustrated in the passage/lecture,...
　　最后，Synthesize，也就是連接。具體來講，就是承接詞的使用是相當重要的，將文章當中的重要信息連接起來，體現作者對于兩篇文章的理解正確，說明作者的思路清楚。由于綜合寫作是對兩篇文章的比較，所以下面表對比和遞進的承接詞使用的最頻繁。
　　a.Transitional words showing contrast: however, on the other hand, in contrast, on the contrary
　　b.Transitional words showing addition: moreover, furthermore, in addition, besides, as well
