NO·1层: No girl 主 have to marry 谓 a man 宾 whose continue title have the alike initial as ITs ,定语语法 for, as the rhyme goes,"Change 状语语法 the title but not the letter, marry for worse instead of preferable."

要点 这是个主从复合句。for是连接词，引导状语语法。as the rhyme goes是插入语，插在for和它引导的语法之间，造成for和它引导的语法的分离，中文英语互译时，可译成唯一主谓框架。译文妞妞不该嫁给与本人的姓的首字母相同的人，因该正如一首童谣所说：改姓不改首字母，婚后必将受其苦。

A method for simultaneous determination of oxytetracycline, tetracycline, chlortetracycline and choramphenicol in seafood was successfully developed using high performance liquid chromatography with ammonium acetate/water and acetonitrile as the mobile phase. The results showed that the four antibiotics were well separated under the optimum conditions, with the limits of detection being 32 μg/kg for oxytetracycline, 15 μg/kg for tetracycline, 23 μg/kg for chlortetracycline, and 19 μg/kg for choramphenicol. The recovery of standard additions was 76~92% and the relative standard deviation was 0.8-4.5%. The method is rapid, sensitive, accurate and reliable and can be applied in the analysis of antibiotic residues in seafood.
