{01}The meeting ________ now is of great importance
A.being held
B.to be held
C.held
D.is being held
解析：考查非谓语动词。句意“现在正在开的会议具有很重要的意义。”根据now可知，是正在进行，而meeting和hold之间是动宾关系，故用被动，相当于which is being held。故选A。
本题选A。
{02}Something must be done to prevent factories sending out poisonous gases so as to keep the city _________
A.polluting
B.from polluting
C.pollute
D.from being polluted
解析：考查动词搭配。keep … from doing sth.阻止某人做某事，根据句意是阻止城市被污染，故用被动，选D。
本题选D。
