（2010•01•江蘇徐州檢測(cè)）
A. not have watched B. not watch
C. hadn’t watch D. haven’t watch
①解析：選B。考查would rather do sth.這一結(jié)構(gòu)的用法。而do, will和should都不能與rather 搭配。would rather (not) do sth.意為“寧愿（不愿意）做某事”。
②解析：選A。would rather not have done意為“本不想做……（實(shí)際卻做了）”。后一句句意為：否則我現(xiàn)在已經(jīng)完成了我的。 所以前句表示“本不想看球賽卻看了”，故選A。
