英语搭配词典,对英语学习者而言,是最有用的专用词典,这方面最好的当属《牛津搭配词典》(Oxford Collocations Dictionary for learners of English)了,不过没有在线版的。这里我也po一个在线版的替代品:

习语 词典 - Idioms by The Free Dictionary https://idioms.thefreedictionary.com/drill+into
有些词汇,需要了解其词源,才能牢记,下面给出相应网站: 单词词源在线查询 | Origin and history of boot by Online Etymology Dictionary http://www.etymonline.com/index.php?allowed_in_frame=0&search=boot
