Because of its synthetic and unique pharmaceutical importance, a continuous development in the synthesis of new enaminones is a growing area research. An impressively diverse range of efficient enaminones synthesis based on new metal-catalyzed condensation reactions or other reactions of appropriate precursors have been developed during past years. However, a plethora of new synthetic methods for preparing enaminones including classical syntheses suffer from low yields, use of expensive or not readily starting materials and exhibit limit substrate tolerance[35]. Therefore, it seems highly desirable to find an efficient, simple and general protocol for the synthesis of enminones。 [ Last edited by sjsjsj2007 on 2011-6-14 at 15:48 ] |

Because of its synthetic and unique pharmaceutical importance, a continuous development in the synthesis of new enaminones is a growing area research. This sentence should be rewritten as "Synthesis of enaminones has been a continuously growing reasearch area due to their unique importance in synthetic and pharmaceutical aspects". 開門見山地強(qiáng)調(diào)主語(yǔ)"Synthesis of enaminones", 把原因狀語(yǔ)放在句首實(shí)屬浪費(fèi)；另外，原文中的its指代不清。 An impressively diverse range of efficient enaminones synthesis based on new metal-catalyzed condensation reactions or other reactions of appropriate precursors have been developed during past years. "An impressively diverse range of methods for efficient synthesis of enaminones based on new metal-catalyzed condensation reactions or other reactions with appropriate precursors have been developed during the past years." 作者是想說過去一些年，許多基于metal-catalyzed condensation reactions或使用appropriate precursors 的enaminones的合成方法被研究開發(fā)出來。原句中的a range of 后面的主語(yǔ)不是很明確和清楚，而且其修飾的名詞應(yīng)該用復(fù)數(shù)形式。 However, a plethora of new synthetic methods for preparing enaminones including classical syntheses suffer from low yields, use of expensive or not readily starting materials and exhibit limit substrate tolerance[35]. However, a plethora of these methods suffer from low yields, use of expensive or not readily starting materials, and limited substrate tolerance [35]. 有了上一個(gè)句子的陳述，此處就很簡(jiǎn)潔的使用these methods就可以了。注意上下文的連貫和簡(jiǎn)潔性，沒有必要重復(fù)交代a plethora of new synthetic methods for preparing enaminones。作者在此句子要引出現(xiàn)有合成方法的局限性，也就是該論文的研究目的，為下一句話做鋪墊用的。 Therefore, it seems highly desirable to find an efficient, simple and general protocol for the synthesis of enminones. Therefore, it is highly desirable to find an efficient, simple and general protocol for the synthesis of enminones. 個(gè)人認(rèn)為，將"seems" 改成"is"的話，語(yǔ)氣似乎更肯定了，表明你做的工作真的很有意義。此句沒有語(yǔ)法問題。 |
