.猜词性阅读
学生在课外阅读过程中,特别是在掠读或检索读时,如果遇到不懂的词或句子,手头又没有辞典的情况下,怎么办?这时学生可利用上下文线索猜测词义。要培养学生高效的阅读能力就要学会利用生词的上下文去寻找猜词懂意的线索。后文的阅读往往能澄清整段的意思,对整段意思的理解又反过来为理解生词提供了整体背景,使学生的猜测有了可寻的线索。猜词性阅读可以通过以下几种方法来进行:
(1)根据构词法理解词义;While early settlers had killed bison for food, now
the killing became more widespread.
widespread是一个合成词。把它分开成为wide, spread就可知其意。
(2)根据上下文理解:Now they could ride horse, it became easier to hunt the bison, a type of cattle which used to exist in huge number on the plains of America. 当学生不理解这个词时, 教师指导学生可根据后面的解释来理解这是 a type of cattle.
(3)根据句了结构理解:Thus one simple fact, a change in the number of bison, had an effect on the whole wildlife chain of the plaons.
通过分析句子成分可知,a change…bison是fact的同位语。主语是fact,谓语是had an effect on …根据上文所述可理解此句。
