问题 单项选择题 A1型题

下列关于浸提方法应用的叙述,不正确的是()

A.渗漉法适用于有效成分含量较低的药材的浸出

B.煎煮法广泛用于各类药材的浸提

C.浸渍法适用于黏性药材的浸提

D.水蒸气蒸馏法常用于含挥发性成分药材的提取

E.渗漉法不宜用于无组织结构药材的浸出

答案

参考答案:B

解析:渗漉法适用于贵重药材、毒性药材及高浓度制剂,也可用于有效成分含量较低药材的提取。但对新鲜药材、易膨胀的药材、无组织结构的药材不适用。因此选项A和E都是正确的。浸渍法适用于黏性药材、无组织结构的药材、新鲜及易于膨胀的药材、价格低廉的芳香性药材的浸提,水蒸气蒸馏法适用于含有挥发性成分的药材,因此选项C和D也是正确的。煎煮法适用于能溶于水,且对湿、热较稳定的有效成分的浸提,并非广泛用于各类药材,因此选项B是错误的。

The Banquet has been described as a loose adaptation(节选)of "Hamlet", featuring royal conflicts(冲突) and revenge(复仇)which is set in 10th century China. The new Emperor (Ge You) has usurped(篡夺) the throne(帝位)by murdering the previous Emperor. He marries the Empress (Zhang Ziyi), wife of the previous Emperor and stepmother to the Crown Prince (Daniel Wu).

At first, the Empress seeks only to protect herself, but as the new Emperor grows suspicious(疑心) of all those around him, she realizes that only by helping the Crown Prince kill him can she hope to survive. Together with the Chief Minister (Ma Jingwu),she tries to carry out this plot, but when the Prince is destroyed by hesitation, she thinks out a new plan and seeks the throne for herself. As the plot move towards its climax(高潮), the Emperor calls for a plentiful royal banquet, where each will seek the end of their enemies.

The Banquet differs from Hamlet in that it does not focus on the prince, but examines the feelings of each character. According to director Feng Xiaogang: "If Hamlet is about a prince who must make a choice involving life and death, then The Banquet is about how each character must face a choice of life or death... All are motivated by desire, but as soon as they have begun their plans must grow more extreme, and they move step-by-step towards the abyss(深渊)... They do not intend evil, but turn to it out of self-preservation and ever-growing ambition(野心)."
