实用技巧与注意事项

- 避免过度替换:同一段落中3-5个核心词汇替换即可,过度堆砌替换词可能导致逻辑混乱。
- 结合同义词词典:积累近义词的细微差别,如“advantage”和“merit”均指“优点”,但“merit”更强调内在价值。
FAQs
问:托福写作中是否需要使用生僻词来提升分数?
答:不建议盲目使用生僻词,评分标准更注重词汇的准确性和恰当性,而非难度,使用熟悉的替换词精准表达,比误用生僻词更易获得高分,用“mitigate”替代“reduce”更准确,但若不确定用法,保持“reduce”的正确使用更稳妥。
问:如何高效记忆托福替换词?
答:可按主题分类记忆(如教育、科技、环境),并结合例句理解用法,整理“教育类”替换词时,将“teach”替换为“instruct, educate, impart knowledge”,并造句“Teachers should not only instruct but also inspire students”,通过语境加深记忆,在写作练习中主动应用替换词,巩固记忆效果。
