Q1对错判断
判断下面句子里 dedicate 的用法是否正确:
The foundation is dedicated to provide clean water to rural communities.
✓ 正确版本
The foundation is dedicated to providing clean water to rural communities.
该基金会致力于为农村社区提供清洁水源。
be dedicated to 中的 to 是介词,后接动名词(providing),不是不定式(provide)。与 commit to、look forward to 同类结构。
Q2近义选词
选择最恰当的词填空:
He ___ three years of his research to studying the migration patterns of Arctic birds.
Adedicated
Bdevoted
✓ 他将三年的研究时间用于研究北极鸟类的迁徙模式。
devote time to 强调「将特定资源分配给某任务」,更侧重资源分配;dedicate 更常用于长期情感层面的「献身/奉献」;此句有具体时间量词(three years),用 devote 更自然。
Q3翻译应用
用 dedicate 翻译下面句子(可参考 writing_upgrade 字段):
那些将一生投身于教育事业的教师,往往是社会进步中最默默无闻却不可或缺的推动力量。
Teachers who dedicate their lives to education are often the most unsung yet indispensable driving forces of social progress.
关键搭配:dedicate their lives to education
dedicate one's life to + 名词 是描述长期奉献的书面核心表达;unsung yet indispensable 构成「让步+强调」结构,适合议论文赞美榜样人物。
