11.Careful surveys have indicated that as many as 50 percent of patients do not take drugs _____ directed.

　　A. like

　　B. so

　　C. which

　　D. as

　　Best Answer：D

　　答案：【譯文】仔細(xì)的調(diào)查表明，多達(dá)50%的病人未按規(guī)定服藥。

　　【注釋】as有“以……的方式、依照”的意思。so做連接詞時(shí)意思是“因此、所以”。so后接分詞時(shí)是副詞，意思是“這樣、如此”。which通常引出定語(yǔ)從句，代表所修飾的名詞，用在本題不合適。like做連詞用以表示兩個(gè)事物的比較。
