技巧点拨
植物相关信息定位法
在阅读植物主题类文章时,先明确题目核心关键词,如植物部位(rt/stem/leaf 等)、动作词(plant/water/dig 等)、用途词(make paper/feed peple 等)、疑问词(what/why/hw 等),再在文章中快速检索包含这些关键词的句子,结合上下文匹配信息、判断答案。例如,题目询问 “What part f the plant helps it absrb water?” 时,可搜索 “absrb water” 相关描述,锁定 “rt(根)” 对应的信息句得出答案。
例:Rice plants need plenty f water and 6-8 hurs f sunlight every day. They grw well in warm places.
( )1. Rice plants need little water t grw.(正确填T,错误填F)
分析:题目关键词为 “Rice plants” “need” 和 “little water”,原文明确提到水稻需要 “plenty f water(大量水分)”,与 “little water(少量水分)” 矛盾,因此答案为 F。
原文:Rice plants need plenty f water and 6-8 hurs f sunlight every day.
