逻辑关系的差异,即段落内句与句之间意思的关联性：
1.That is not to say that lack of face-to-face communication brings no problems.One of the biggest concerns is safety.With the increasing virus threats and well-trained hackers,online deals are well exposed to all kinds of risks and losses,for example,the wide-spread problem of identity theft.（正确的写作方向）
解析：通过分析可以看出，句与句之间关系对应严谨，对应关系依次为：“problems–safety-virus threats and well-trained hackers-risks and losses-identity theft”.句子之间“环环相扣”，形成一条“逻辑链”。
2.Why Is English Important to Scientists
1）We live in a world which science and technology is developing very quickly.2）The developing of science needs scientists from all over the world exchange their work more and more frequently.3）However,the scientists come from different countries usually speak different languages.4）If there isn't a common language that can be understood by everybody,they won't understand each other.5）On the other hand,we wish to know what others are doing and what experiences and knowledge and things we should learn to improve our work,so we must master the foreign language.6）However,there are countless languages in the world,we cannot learn all of them.7）Fortunately,there is one kind of language that is commonly used all over the world,English.Most of the scientists of the world can speak and read and write English,most of the important academic meetings use English,if we master English,we can go to any corner of the world to exchange with the people without knowing their mother language.We can say we are holding one of the very powerful weapons of study science.（不符合英语写作习惯的段落）
解析：文中句说明了情况,提出了一个问题,在没有解决问题的同时又立即用On the other hand提出了另一种情况和问题,接着又However提出第3个问题,直到第7句又引入了到“英语"这个主题上。句间意思上关联性不直接。
雅思写作考察的重点：表达方式不仅要符合基本的英语表达习惯，更为重要的一个重点为语言组织能力与逻辑推理能力，即所说的逻辑关系：段落内句与句之间必须有紧密的联系，达到“串联”的效果。
结论：当然，中英思维方式的差异远远不止这些，但在备考雅思写作时，如果能够明确了解这些基本的差异，通过大量的实战练习掌握英语的表达习惯及行文逻辑，从根本上把思维方式扭转过来，基础薄弱的同学可以在原有基础上提升分数；有一定基础的同学基本可以达到小分要求；基础良好的烤鸭们，那就是写作的预备军了。
希望可以帮助所有烤鸭达到理想的成绩！
