SAT语法题,本人英语基础不太好请解答的详细些麻烦了.

一、Not many authors have described the effects of environmental pollution as effective as Rachel Carson shoes work is still a model for nature writters.

1、大结构
主句：Not many authors have described the effects of environmental pollution as effective【动宾结构】,
状语从句：as Rachel Carsonm shose work is still a model for nature writters.　【系表结构】

2、比较结构as … as 中,第一个as 是副词,意思是“同一程度地/那样地”,第二个as 是连词,表示“如同…一样”.

3、as effective 在主句中应该是修饰动词described 的程度状语,即“那样有效地记述”.但是,effective 是形容词,不能作这类状语,应该改为副词effectively.

参考译文：
直译：不是许多作者像蕾切尔·卡森足不出户的工作依然是给自然作家树立的范本那样有效地记述过环境污染的影响.
拆译：蕾切尔·卡森足不出户的工作依然是给自然作家树立的榜样,许多作者并不都像他那样有效地记述过环境污染的影响.

二、a clever designed reservoir中,过去分词designed修饰 reservoir（意思是“被设计出的水库”）,clever 修饰过去分词designed,说明设计的方式,但是clever是形容词,不能修饰过去分词,应该改为副词cleverly,即“以巧妙方式设计”.

　　a cleverly designed reservoir 意思是“一座巧妙设计的水库”

1. as effective as应该是as effectively as,因为该短语修饰的是动词described，该用副词，

2. 还有a clever designed reservoir也不对，也应该用副词cleverly来修饰动词designed
