满分作文的三大核心是结构、内容和语言。
首先我们先从结构、内容和语言三个方面揭秘托福作文独立任务得满分的真相。
以下题为例： Do you agree or diagree with the following tatement? Life today i eaier and more comfortable than it wa when your grandparent were children. Ue pecific reaon and example to upport your opinion.
一、结构
按题材划分，独立任务属于议论文，而论点、理由、论据、结论和论证是议论文的五个要素。具体来说，“论点”是文章的核心，“理由”是论点成立的依据，两者构成因果关系;“论据”是对理由的具体解释，多为事例;“结论”是对观点的重申，两者一脉相承、头尾呼应;而整个写作过程就是一个“论证”的过程。
要想作文得高分，这五要素就必须面面俱到，如此才能写出结构严谨、条理清晰的高分作文

【提出建议，展望未来】
议论文除了五要素，在给出论点之前多会有简单的背景介绍，不需要长，三两句话即可，为论点的提出造势。
二、内容
这篇范文通过通讯、交通和饮食三个方面，共同论证现在的孩子相较其祖父辈生活的更轻松、舒适，每个理由下面都有具体的事例作为细节支撑，让论证更有说服力。
以饮食为例，作者举例说，以前食品由政府分配，数量有限制，人们不能随心所欲买到需要的食品;而现在则大不一样，在超市里人们可以买到任何所需物品。这种新旧对比，更鲜明的表现出现代社会物资丰富、人们的选择权增加，由此可推断人们的生活变得更便捷、舒适，从而证明论点。
三、语言
一篇高分作文在语言上，首先要保证语法正确，用词恰当，这样才能准确达意。在此基础上可以追求更多样、高级的表达。例如，文章开头要表现“社会发展迅速，人们的生活发生了天翻地覆的变化”这一含义，最常见的表达为：
Sample 1: Our ociety develop quickly, and people’ life ha changed greatly.
Sample 2: With the rapid development of ociety, enormou change ha happened in people’ life.
Sample 3: A ociety progree remarkably, tremendou change have taken place in people’ life.
通过三个句子对比可知，其中“迅速”的三种表达方式，quickly 最为平淡，rapid 居中，remarkable 最佳。同样的，要表达“翻天覆地”的含义，tremendou 就要比 great 或者 enormou 好的多，其他替换的词还有 coniderable，dratic，ignificant 等等。
语言的优化需要不断的积累和练习，多记多练，不断扩充自己的语料库，唯有如此，文章才会写的越来越漂亮，但是咱们很多考生平时不练笔，不积累语料，想单纯依赖“复杂单词，黄金句型”就拿高分——基本没戏。
希望上述对你有帮助！
