The invention of the computer is the most important________in the world in these years．


  1. A.
    invent
  2. B.
    invention
  3. C.
    invitation
  4. D.
    event
D
分析：空格詞在the most important之后，應(yīng)該是名詞。A．invent是動詞，應(yīng)予排除。C．invitation“邀請”，和句意不符。B．invention是名詞，似乎可以，但放到整個句子中句意成為“我認為計算機的發(fā)明是這些年里世界上最重要的發(fā)明�！憋@得重復(fù)。應(yīng)該選D項event，句子就很通順。按理說event(事件)的范圍是很廣的，政治、軍事、科學等都包含在內(nèi)，很難說計算機的發(fā)明是最重要的事件。但這是1個人的看法，所以應(yīng)該是成立的。(延伸)event一般只是指“運動”的“項目”，別的項目用item表示。
