学生升入高三后,高考的号角已经吹响,高考的脚步日益加快,可谓时间紧、任务重、压力大。在这非常时期,高效复习显得尤为重要。因此,教师要研究教材,研究高考,把握重点,突破难点,明确考点。下面笔者就“考点”的发散思维这一话题略述管见,以期对备考中的莘莘学子有所帮助。

纵观历年的高考单项选择题,我们不难发现,对同一知识点的考查不断重复出现,只是命题的角度不同而已。这就要求我们在教学中多角度地分析问题,形成发散思维。下面举例说明:(1)祈使句+and/or+陈述句,针对这一句型,可以从三个角度进行设题,一是考查祈使句;二是考查连词and/or;三是考查陈述句中的时态。(2)not ...until...,考查该句型有两点,一是用于强调句中;二是转化为倒装句。

这样的例子有很多很多,不胜枚举。我们从中得到的启发是:对于“考点”的多角度分析能使我们在复习过程中节省时间,节省精力,避免题海战术,把学生搞得疲惫不堪,而且通过比较分析,归纳总结等过程,拓宽思路, “闻一以知十”,引导学生多方位、多视角思考问题和解决问题,形成良好的思维品质,进而使学生感受到成功的喜悦,对学习产生浓厚的兴趣。

对“考点”的发散思维,适宜于词汇、句型、语法等知识点的学习与复习,比如词性转换、同义词的辨析与替代、反义词的归纳、句型之间的转化,一句多译。通过这方面的训练,能使学生牢固掌握基础知识并灵活运用,书面表达也因此得以提升。
