So many directors____,the board meeting had to be put off. A were absent B been absent C had been absent D being absent 选D是正确的 这个句子是句首现在分词做状语的结构,属固定用法. being absent的原形是be absent(缺席),把它放在句首时,如果是主动就变成现在进行时,如果是被动就主变成过去分词结构,对于这题来说刚好是主动(老师缺席,不是老师被缺席吧),也就是为什么选D的原因了. We left the meeting ,there obviously __no point in staying A were B being C to be D having 选B是正确的 这一题同上面的那题是一个类型的,只不过句首变成了句末,另外这一题是there be 的结构来做条件从句。 这里就不再多说,参考前面一题就行了。
