托福词汇备考中如何有效地背诵单词呢?本文中小编就为大家讲讲有关如何有效地背诵单词?
　　按话题cluster背诵单词
　　memorize vocabulary “thematically”。比如托福单词可以按地理，物理，天文，生物，动物，建筑，艺术，历史，人文，科技，教育，校园，环境等话题记忆单词。口语听力阅读写作都可以按照这个思路积累词汇，考试在遇到相关话题时，能快速激活所背词汇。托福听力lectures主要分为四大类：arts;life science;physical science;social science ，然后在细分话题词汇。
　　按词组背诵
　　语言学家Michael Lewis推崇语言学习要按词组in lexical chunks(phrases)来背单词，而不是on a word-by-word basis记忆单词。有的考生在写作口语中通过中文直译，导致使用大量怪异的难词搭配，就是我们所说的中式英语Chinglish。如realize self-achievement;achieve self-independence;The speed of high speed train is almost as fast as plane。
　　按单词出现频率背诵
　　具有2000高频词汇量的学生能够理解几乎80%的普通文本;1800高频词汇就能进行80%口语对话。在听力阅读中经常遇到的生词就非常重要，需要记下。
　　展开全文经常使用
　　“Connect new words with your own experiences.” 在背贴背的1号线地铁车厢内背诵有关’crowded’词汇就很应景。Google搜索“beijing subway crowded”，可以找到如下表达：in rush hour;those with claustrophobia;is packed with commuters;packed like sardines(If people are packed or squashed like sardines, they are positioned very close together so that they cannot move: We were squashed like sardines in the rush-hour train.);those coming off the train have to almost stage battle with those wanting to get on;pushing and shoving;be physically pulled off the train by another commuter。
　　背同义词
　　托福阅读中有数题是考词汇同义词;口语也可以进行替换，使语言表达更加丰富。
