1 把形容词放在它们所描述的名词之前，或使用定语从句
S1. *We examined a patient, 30 years old, to investigate whether …
S2. We examined a patient, who was 30 years old, to investigate whether …
S3. We examined a 30-year-old patient to investigate whether …
**S1是错误的，S2用从句解决了这个问题，S3用连字符将名词变成形容词。注意连字符的使用。然而，不要担心这方面，许多母语人士也会在连字符上犯错误，如果你在这方面犯了错误，审稿人是不太可能作出评论的。
2 形容词不能放在两个名词之间，不要修饰错误的名词
S1. * The editor main interface. (反例)
S2. * The algorithm computational complexity.(反例)
S3. The main interface of the editor.
S4. The computational complexity of the algorithm.
S5. * The main document contribution (反例，修饰了错误的名词)
S6. The main contribution of the document
3 避免用名词串修饰名词
我们不能说 art state technology (state-of-the-art technology) or mass destruction weapons (weapons of mass destruction). 但是可以说 a software program or an aluminum tube .
以英语为母语的人确实倾向于把名词串在一起，但他们直觉上知道怎么做。事实上，他们没有遵循任何书面规则，而是以已经存在的例子为基础。如果母语不是英语，建议你在谷歌Scholar上验证提出的一串名词是否已经存在，并且已经被母语为英语的作者使用过。
4 避免产生歧义
歧义句举例
S1. *Professors like annoying students.(annoying 动词还是形容词)
S2. *I spoke to the professor with a microphone. （修饰I or professor）
S3. *To obtain red colors, insects and plant roots were used by indigenous people. (读前面时可能认为是并列的)
S4. The European Union (EU) adopted various measures to combat these phenomena. This resulted in smog and pollution levels reduction.(不够直接需要作者转换解释，reduction in smog and pollution levels)
S5. We also demonstrated that x does not equal y as suggested by Walker (2011). (不知道Walker 研究是equal 还是 not equal)
