试比较以下两种TOEFL听力表达方式：1)He spent a lot of money.（他花了大笔的钱。）2)He spent a lot of money, like water.（他花钱如流水。）很明显，第二种表达方式比第一种更加生动和形象。因为like water（如流水）使用了Simile（明喻）的修辞手法，这样以来，无疑使语言更加精彩和完美，听力考试也不再单纯是一门考试，而变成了一种享受。Simile（明喻）一词源于拉丁语similes,其意为like（象）。他借助人们的想象力，使用一定的比喻词如：like, as等加以连接，从而清楚的表明两种事物之间的相似之处，使得表达更加新鲜有趣。其典型形式是A is like B. Simile（明喻）的修辞手法在TOEFL听力中的运用可谓炉火纯青。比如：(划线部分为明喻之处) 1．Like引导1) He sweats like a pig.(他像猪一样流汗。) 2) They slept like babies.(他们像婴儿一样熟睡着。) 3) Living without an aim is like sailing without a compass.(John Ruskin)（生活没有目标犹如航行没有指南针。）4) Records fell like ripe apples on a windy day.(E.B. White)（被打破的记录犹如刮风天成熟的苹果——纷纷坠落。）2．As引导1）She is as beautiful as a flower.（她像花一样的美丽。）2）“I am as light as a feather, I am as happy as am angel, I am as merry as a school boy. I am as giddy as a drunken man...”(Charles Dickens)（我像羽毛一样轻，我像天使一样幸福，我像小学生一样快活，我像喝醉了酒的人一样飘飘然……）3）The first time I read an excellent book, it is to me as if I had gained a new friend. （我头一回读到一本好书，对我来说好象交了一位新朋友。）注意：As引导的as...as结构在英语中得到了广泛应用，若能在口语交流或各种作文考试（如：TWE等）中用上一个，定会得到意想不到的效果，常用的as结构有：(as) firm as a rock坚如磐石(as) light as a feather轻如鸿毛(as) close as an oyster守口如瓶(as) mute as a fish噤若寒蝉(as) strong as a horse强壮如牛(as) cool as a cucumber泰然自若(as) sober as a judge十分清醒(as) sure as a gun千真万确
