单选题 _______ such heavy pollution already , the river is no longer what it used to be .And the City Council concludes that it may now be too late to clean it up .A.Having sufferedB.SufferingC.To sufferD.Suffered

A解析测试语言点 ：动词的现在分词作为状语，表达因果关系的不同层次。要吸取的经验 ：要依据上下文选词填空。上文： such heavy pollution already ,遭受如此严重污染 ，下文 ： it may now be too late to clean up the river .结果清理河道为时已晚。不过，这里是下文决定上文；既然清理河道为时已晚，那么其原因必然是“已经”严重污染到不可挽回的地步了。所以，选B． Suffering表示现在正在受到污染，其层次不够，C． To suffer表示目的，D． Suffered仅仅可作谓语，都不对。※ 此题有语病。按照“托福考试”（TOEFL）要求，应视为“修饰语不合逻辑”（Illogical modifiers）。下面的一对句子选在自1979年的“BARRON扴 HOW TO PREPARE FOR THETOEFL”一书（p.80）：Incorrect: Having been delayed by heavy traffic, it was not possible for her to arrive on time.Correct: Having been delayed by heavy traffic, she arrived late.这个句子是1994年1月“托福考试”第32题，与上述错误相似。Judging to be the best boxer of his time , Sugar Ray Robinson lost only 3 out of 137 fights. ABCD ※※此题的正确命题似乎应该是这样：_______ such heavy pollution already , the river is no longer what it used to be .And the City Council concludes that it may now be too late to clean it up .[]A． Having suffered B． SufferingC． To sufferD． Suffered※※※关于此题“有语病”的看法，2004年在上海卷（42）中，再次得到验证： 42. Having been attacked by terrorists, ________ []A． doctors came to their rescue.B． the fall building collapseD． C． an emergency measure was taken.D． warnings were given to tourists. Key: B
