SAT閱讀詞匯學(xué)習(xí) 謂語動(dòng)詞.

　　今天我們要學(xué)習(xí)SAT閱讀詞匯中的謂語動(dòng)詞(Verb or Predicate)，謂語動(dòng)詞是文章每句話主要意思的體現(xiàn)者。換句話說，只要能把SAT閱讀文章中每句話的謂語動(dòng)詞讀懂，那么整篇文章的主干意思也就非常清晰明了了。這就是學(xué)習(xí)SAT閱讀詞匯的作用。我們來看下面一段文字：

　　The floor of a river valley develops in one of two ways: as a rock-floored valley bottom or as an accumulation valley floor. A rock-floored valley is formed by a stream that no longer incises by cutting downward but rather erodes laterally in a course that winds from side to side across the valley floor. In a rock-floored valley, the valley slopes are undercut and steeped by the sideways erosion. The floor of the river channel lies in the bedrock, and on either side of the channel it is covered by only a thin layer of gravel and sand. As the stream swings across the valley floor, it deposits material on the insides of the bends in the channel.

　　通過對(duì)上面文字各個(gè)句子中的謂語動(dòng)詞的重點(diǎn)標(biāo)示，讀者應(yīng)該會(huì)發(fā)現(xiàn)，文章的理解難度大大降低了，我們也不再用去無聊地思考為什么風(fēng)能從一邊到另一邊地吹過峽谷底部了(winds from side to side across the valley floor)，因?yàn)槲覀冎乐匾氖撬伎紃ock-floored valley是怎么形成的(formed)，它怎么變陡峭的(undercut and steeped)，它所在的位置在哪里，被什么東西覆蓋(lies and covered)，以及它沉淀物質(zhì)在什么地方(deposits)。

　　以上就關(guān)于SAT閱讀詞匯中的謂語動(dòng)詞(Verb or Predicate)的學(xué)習(xí)，大家可以再好好琢磨一下上面這個(gè)例子，把它弄明白。接下來的工作就是自己找一些SAT閱讀文章，用上面介紹的方法進(jìn)行學(xué)習(xí)。
