　　托福閱讀長難句分析：

　　這個句子的主干部分是：

　　A fertile, plowed field is rapidly invaded whereas a neighboring construction site may remain virtually free of vegetation

　　whereas然而，表示對比，對比兩種情況

　　修飾一：(by a large variety of weeds) ，介詞短語

　　中文：被各種各樣的雜草

　　修飾二：(from which the soil has been compacted or removed to expose a coarse, infertile parent material) ，從句，修飾a neighboring construction site

　　這個句子理解的難點應(yīng)該就在這里了，這個從句把a neighboringconstruction site和may remain virtually free ofvegetation分開了，注意斷句不要出問題，這種現(xiàn)象之前我們碰到很多了。
