新课改以来,北京高考理综化学有机试题的分值均约占化学总分的17%左右,试题均以合成题的形式呈现,具有源于课本、又略高于课本的特点,是综合考查有机物性质的一类试题.由于有机物的性质主要由官能团决定,而试题中的有机物又同时具有多种官能团,因此,在进行有机化学专题复习时,要采取“回扣课本、夯实基础、以基为基、基团作战”的复习策略.具
Since the new curriculum reform, the scores of organic chemistry test in Beijing college entrance examination all account for about 17% of the total chemistry. The questions are all presented in the form of synthetic questions, which are derived from textbooks and slightly higher than textbooks. As a result of the nature of organic matter is mainly determined by the functional group, and the organic matter in the test also has a variety of functional groups, therefore, in the review of organic chemistry, we should take “rebate textbooks to lay a solid foundation to Base-based, group combat ”review strategy
