在教學過程中，強調讓學生多寫單句，單句寫好了，復雜句也會寫。這個做法可能和大部分的老師是相反的。但這個教學方法基于一個簡單的道理：雅思考官不好蒙騙。你一個復雜句如果寫的不對，考官馬上可以看出來，分數馬上就會降低。因此，踏實寫好簡單句，分數更加容易提高。
只有當你熟悉單句后，才可以將句子連接起來。
方法1：如果兩個簡單句沒有因果關系，基本上是兩個獨立的事情，往往可以簡單地用and相連。
舉例：Children are not sensitive to prices and parents prefer to satisfy their needs.
方法2：如果兩個簡單句有一定的因果關系，往往可以用狀語從句相連。
一般來說，if 和when引導條件狀語從句(也有一定因果關系，只是不那么強)
舉例：If advertising campaigns directed at children are regulated, children will not pester their parents to buy many goods for them.
Since, as, because, so等引導原因或者結果狀語從句，表示比較強的因果關系
舉例：some children like fast food since they are overwhelmed by fast food advertisements every day.
方法3：如果狀語從句怕重復，可以用and(或者;)+連接詞的方式
有很多連接詞because of this, as a result of this, consequently, as a consequence 等，都是表示因果關系。
舉例：some children are addicted to violent video games, and because of this, they can show aggression and bully their peers at school.
方法4：如果第一個單句的最后一個單詞和第二個單句的第一個單詞重復，可以用定語從句連接。
舉例：Children are increasingly temperamental due to their addiction to violent electronic games. These games are normally promoted by advertising firms.
可以改成：Children are increasingly temperamental due to their addiction to violent electronic games, which are normally promoted by advertising firms.
方法5：如果第二個單句是第一個單句的結果，有可能使用非限制性定語從句
舉例：Advertisements have given a lot of information about products. This enables parents to make well-informed buying decisions.
可以改成：Advertisements have given a lot of information about products, which can help parents to make well-informed buying decisions.
簡而言之，不要嫌棄簡單句，簡單句寫熟了，復雜句很容易寫。
