導語：對於一些簡單句，我們可以適當擴充，把它優化成一個比較複雜的句子，不僅可以增加作文的字數，還可以令老師刮目相看哦。下面YJBYS小編分享大學英語作文句型擴充技巧，歡迎參考!
一、避免使用語意弱的“be”動詞。
1、把句中的表語轉換爲不同的修飾語，這個技巧並不是那麼容易掌握，但是確實是一個能夠提高雅思寫組成績的非常實用的技巧。
例如：
Weak: The trees are bare. The grass is brown. The landscape seems drab.
Revision: The brown grass and bare trees form a drab landscape. (轉換爲前置定語)
Or: The landscape, bare and brown, begged for spring green. (轉換爲並列結構作後置定語)
2、將作表語用的形容詞或名詞變爲行爲動詞。
例如：
1) Weak: The team members are good players.
Revision: The team members play well.
2) Weak: One worker's plan is the elimination of tardiness.
Revision: One worker's plan eliminates tardiness.
3、在以“here”或“there”開頭的.句子中，把“be”動詞後的名詞代詞變成改寫句的主語。
例如：
1) Weak: There is no opportunity for promotion.
Revision: No opportunity for promotion exists.
2) Weak: Here are the books you ordered.
Revision: The books you ordered have arrived.
二、多用語意具體的動詞，保持句意簡潔明瞭。這樣的具體描寫可以讓文章看起來更具說服力，當然也就可以提高雅思寫作成績了。
例如：
1、Poor: My supervisor went past my desk.
Better: My supervisor sauntered (=walked slowly) past my desk.
2、Poor: She is a careful shopper.
Better: She compares prices and quality.
三、儘量運用主動語態。之所以要這樣做，是因爲很多人不明白什麼時候該用主動，什麼時候該用被動。用錯了，當然也就談不上提高雅思寫作成績了。
例如：
1、Weak: The organization has been supported by charity.
Better: Charity has supported the organization.
2、Weak: The biscuits were stacked on a plate.
Better: Mother stacked the biscuits on a plate.
四、防止使用語意冗長累贅的詞語。想要提高雅思寫作成績就得使寫作的用詞簡單，生動。
例如：
1、Wordy: My little sister has a preference for chocolate milk.
Improved: My little sister prefers chocolate milk.
2、Wordy: We are in receipt of your letter and intend to follow your recommendations.
Improved: We have received your letter and intended to follow your recommendation.
3、Redundant: We had a serious crisis at school yesterday when our chemistry laboratory caught fire.
