题目内容
12.The issuebeing discussed (discuss) at the meeting now is of great importance.分析 此刻会议上正在讨论的问题很重要.
解答 答案是being discussed.本题考查非谓语动词做定语,题干中需要的是the issue的定语,故用非谓语的形式做定语:动词不定式作定语表示将来;现在分词表示进行;过去分词表示被动和完成;由题干中的时间状语now判断用现在分词做定语;此外the issue和discuss 之间是被动关系,故需要用现在分词的被动语态,因此答案是being discussed.
点评 本题是要求用所给词的适当形式填空,解题时首先根据句子的结构考虑句中需要的词性;其次,关注所选词的形式的变化:如果是谓语动词关注时态、语态和数的变化;如果是非谓语动词要联系非谓语的基本用法判断非谓语的形式.如果是名词关注单数和复数的选用等.
