A. and B. for C. but D. or 解析： “his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因， 因此本題應(yīng)選用可以表示原因的連詞for引導(dǎo)原因狀語從句。答案： B誤區(qū)提醒 除了because , since , as , for這四個(gè)詞的辨析外，對(duì)于because 從句與 because of短語的區(qū)分也是難點(diǎn)之一。Because引導(dǎo)的原因狀語從句有時(shí)可與because of 短語轉(zhuǎn)換，because of后跟的是短語 ，because后跟的是句子。典型例題：He didn39。t go to work the heavy rain.
