SAT 2006.1真题语法问题有一道题语法题感觉有点怪(括号表示可能有错的地方):(Not many) authours (have described) the effects of enivironmental pollution (as effective as) Rachel Carson,whose work is still (a model for) nature writers.

原句除了没有用副词effectively之外没错啊~
主句里的平行是autheor have described 对 Rachel Carson has described,但是 has described 可以省略.
举例:He knows more than I (do).
She is more effective than he (is).
I have been a better student than he (has been).
