句子结构是雅思写作评分标准“语法的多样性与准确度”中一项十分重要的考量因素，但这并不意味着要求考生具备写长难句的能力。在追求输出像雅思阅读一样精到的语言之前，我们首先要确保的应当是写出来的句子是正确的。有效的句子甚而段落通常应当同时满足以下五个要素：一致、连贯、简洁、强调、多样。

1. 一致：如句内的逻辑关系，注意检查是否存在简单推论、逻辑残缺、逻辑悖论、依赖偏见等。

2. 连贯：这个问题在平行结构、共用主语、使用指代的情况下尤其需要注意。

4. 强调：正如每篇文章都要有中心思想(main idea)，每个段落都要有主题句(topic sentence)一般，每个句子都要围绕一个中心观点清晰地呈现出作者想要表现的重点。
