          A.WhateverB.WheneverC.WhoeverD.However
          A

          試題分析:考查主語從句:根據(jù)句意:當我們實施的時候,提前計劃的事情可能會改變。用whatever引導(dǎo)主語從句,相當于anything that,B. Whenever無論何時,C. Whoever    凡是…人,無論誰,D. However無論怎樣,選A。
          點評:疑問詞+ever 可以引導(dǎo)狀語從句,相當于no matter+疑問詞,也可以引導(dǎo)名詞性從句,whatever相當于Anything that,whoever相當于anyone who。
