如何提升托福写作中的逻辑关联性
托福写作尤其是独立写作要求大家具备很强的逻辑能力，因为写作中的前因后果需要符合逻辑，不能将不符合逻辑关系的因果强行联系在一起。下面小编就和大家分享如何提升写作中的逻辑关联性，希望能够帮助到大家，来欣赏一下吧。
托福写作重逻辑 如何提升写作中的逻辑关联性
一.官方对托福写作逻辑性的要求
首先我们来看一下OG是如何要求well-developed的：
ave I done my best to support and develop my ideas?(有没有支持立场的分论点?)
o I include enough details in each paragraph so that the main idea andtopic sentence are explained fully?(每段是否有很充分的细节支持分论点?)
o I use words and phrases that help the reader think about relationshipsbetween different ideas in the essay?(句与句之间是否有用逻辑连接词/短语?)
二.逻辑推理要合理
每个段落要做到很好的展开，就要注意句与句之间的逻辑性。官方指南OGP中介绍了很多种展开的方法，包括讲故事、举例子、说道理等等，同时补充了大量的逻辑连接词。同学们习惯于把逻辑连接词/短语事先准备好，平时练习或者考试时都先打出来再往里面僵硬地填充内容，以为可以骗过e-rater和考官。但在这些逻辑词下，我们往往会看到同学写出这样的内容：因为独生子女，所以自私;因为科技和经济发展，所以压力大。
其实第二句和第一句之间并没有直接的因果关系，第二句并不是对第一句的进一步论述，所以即便有暗示逻辑关系的连接词/短语，内容上并非如此。也就是不符合评分标准中的渐进性(progression)。
在“因为独生子女，所以自私”的例子中，我们可以这样推理：独生子女(only-child)→得到更多家人的关注(limelight)→缺少付出的意识(lessgive, more take)→自私(egoism);此外，独生子女→缺少和兄弟姐妹的相处(interact withsiblings)→缺少分享的意识(share)→自私。
这样的两条简单逻辑链就可以推出“自私”的结果。
三.托福写作逻辑能力需要多练习
对于提升托福写作中展开逻辑链，小编建议大家结合托福写作机经中的主题句，在草稿纸上用中文关键词罗列因果链，训练演绎推理的方法，反复追问因果关系(causality)是否成立。通过这种方式来训练自己的逻辑思维能力，进而逐步学会展开的写作思路和方法。
提升托福写作离不开逻辑能力的提升，大家在平时写作练习中要注意逻辑的关联性，如果逻辑能力尚有欠缺，建议在写作之前先打草稿做推理，然后再开始写作。
托福写作：病句的改造
1). 破碎句
所谓破碎句，就是句子不完整，通常是没有谓语(或者说谓语是动词的非谓语形式，如分词)，或者是从句单独成句。
破碎句：She singing alone. (无谓语，singing是现在分词)
正确句：She is singing alone.
破碎句：He did not come. Because he was sick. (从句单独成句)
正确句：He did not come because he was sick.
2).接连句
所谓接连据，就是两个句子直接连在一起，既未使用连词，也未使用正确的标点符号。
接连句: Professionals such as lawyers or accountants usually work longer hoursthan factory workers they have greater freedom in planning their time.
正确句一: Professionals such as lawyers or accountants usually work longerhours than factory workers. However, they have greater freedom in planning theirtime.
正确句二: Professionals such as lawyers or accountants usually work longerhours than factory workers; however, they have greater freedom in planning theirtime.
3).句子连接不正确
所谓句子连接不正确，就是两个独立的句子之间以逗号连接，这是不合英语语法的。正确的做法是以连词、分号、冒号、句号等连接两个句子。
不正确句: Breaking chalk into two pieces is a physical change, there is nochange in the composition of the chalk.
正确句：
Breaking chalk into two pieces is a physical change, so there is nochange in the composition of the chalk.
