(TPO32, 56)

　　长难句分析：

　　这个句子的主干部分是：

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

　　whereas然而，表示对比，对比两种情况

　　修饰一：(by a large variety of weeds) ，介词短语

　　中文：被各种各样的杂草

　　修饰二：(from which the soil has been compacted or removed to expose a coarse, infertile parent material) ，从句，修饰a neighboring construction site

　　这个句子理解的难点应该就在这里了，这个从句把a neighboringconstruction site和may remain virtually free ofvegetation分开了，注意断句不要出问题，这种现象之前我们碰到很多了。

　　中文：这里的土壤被紧压或移除过以至于露出母质层(不要去理解啥是parent material，学术名词)

　　修饰三：(for many months or even years) ，介词短语

　　中文：几个月偶然甚至是几年

　　修饰四：(despite receiving the same inputof seeds as the plowed field.) ，介词短语

　　中文：尽管得到了和这块翻耕地同样多的种子

　　参考翻译：

　　一块肥沃且被翻耕过的土地会被各种各样的杂草迅速入侵，然而一个邻近的建筑工地(这里的土壤被紧压或移除过以至于露出母质层)可能几个月甚至几年都几乎没有植被覆盖，尽管得到了和这块翻耕地同样多的种子。
