With the help of the traditional comparative approach and based on the research done by older generation, the author proceeds from the fundamental viewpoints of cognitive linguistics and from both the positive depiction argument exploration, specifically discussing the feature of "Provided p, q" being distinguished from "If p, q": Clause p in "Provided p, q"only indicates the minimum condition resulting in q while Clause p "If p, q" is not necessarily the minimum condition to the result q.

本文从认知语言学的基本观点出发，借助传统的比较方法，在前辈研究的基础上，从实证描写和理据探究两个方面，着重论述"只要p ，就q"区别于"如果p ，就q"的一个特征："只要p ，就q"所引导的分句p一般只用来表示导致结果q的最低条件，而"如果p ，就q"所引导的分句p对于结果q来说则并不一定是最低条件。

At last,a convergent and general protocol to marine natural product,as demonstrated by the enantioselective total synthesis of malyngamides O,P,Q,R, 5"-epi-Q and 5"-epi-R bearing terminal vinylic chloride structure,was developed in detail.E,(7S)-7-methoxytetradec-4-enoic acid was prepared using the above described Johnson-Clainsen rearrangement,the terminal vinyl chloride was constructed using Wittig reaction as key step,the pyrrolidone derivative was constructed using L-serine as natural chiral pool.Starting from the synthesis of malyngamides O and P to explore the general route,an aldol reaction of methyl acetate with the vinyl chloride part in the presence of LDA gave the skeleton of amine portion,followed by amidation with the fatty acid finished the synthesis of malyngamide P.

先以malyngamides O和P为试点探索通用合成路线，将乙酸甲酯和烯氯部分在LDA存在下进行aldol反应得到氨部分的骨架，再将手性不饱和脂肪酸和氨部分进行酰胺化反应完成了malyngamide P的合成，将P在碱性条件下进行烯醇甲基化反应完成了malyngamide O的全合成。
