試題分析：考查名詞性從句和非限制性定語(yǔ)從句。As引導(dǎo)非限制性定語(yǔ)從句放句首時(shí)，后常有逗號(hào)與主句分開(kāi)，is known to us all后無(wú)逗號(hào)，排除A；it作形式主語(yǔ)的句型是it is known to us all that...，句中that前有is，排除C；主語(yǔ)從句缺少主語(yǔ)，用what，構(gòu)成what ... is that...句型。非限制性定語(yǔ)從句中的life是主語(yǔ)，即life was hard for the old worker。用whose的話，for whose life是介詞短語(yǔ)，從句缺少主語(yǔ)。故選D。
