单选题 So many students ______ the teacher threw the textbook in a fit of anger.
  • [A] were absent-minded
  • [B] be absent-minded
  • [C] been absent-minded
  • [D] being absent-minded


【正确答案】 D
【答案解析】非谓语结构题。在没有连词连接的情况下，可以用独立主格结构作为分句来表达与主句间的关系，本题中独立主格结构的主语为so many students，谓语为be absent-minded，由于主语与谓语的主动关系，故用-ing形式。
