The medical waste that has fouled beaches in the New York region at the peak of the summer season has taken its toll on business all along the shore, driving vacationers away both from beaches that have been closed and from those that have remained open.

　　參考答案:

　　要點(diǎn)：本句主要結(jié)構(gòu)是the medical waste...has taken its toll...。that...season引導(dǎo)定語(yǔ)從句，修飾medical waste。at the peak of the summer season作狀語(yǔ)，表時(shí)間。driving...是現(xiàn)在分詞作狀語(yǔ)，表結(jié)果。that have been closed和that have remained open是定語(yǔ)從句，分別修飾beaches和those。those代替beaches。

　　譯文：醫(yī)療用品生產(chǎn)廠家的廢棄物污染了紐約地區(qū)的海濱。時(shí)值盛夏，一些海濱浴場(chǎng)關(guān)閉，而仍然開放的一些海濱浴場(chǎng)也門可羅雀，大批度假者離此而去，這使得海濱地區(qū)的商業(yè)蒙受嚴(yán)重?fù)p失。
