Be8.Time _, the celebration will be held as scheduled.A. permit B. permitting C. permitted D. Permits解析：Time permitting独立结构作条件状语=If time permits，把time看做逻辑主语，用permitting表示主动。C表示被动， A，D是做谓语，根据主语的单复数定， 同时还要有连词when ,if等9.Agriculture is the countrys chief source of wealth, wheat _ by far the biggest cereal crop.A. is B. been C. be D. Being解析：因为前半句Agriculture is the countrys chief source of wealth 已经是个完整的句子，而后面又没有连词，所以不可能再出现动词，排除A和C，而B没有这种用法，正确的独立主格表示完成时的结构应该是 having been，所以B错。Exercise1. He wasnt asked to take on the chairmanship of the society, _ insufficiently popular with all members.A. being considered B. consideringC. to be considered D. having considered解析：现在分词作状语，此句用的是被动形式。现在分词在句中作状语，修饰谓语动词或整个句子，表示动作发生的原因，结果，时间，方式，条件等。此句是表原因。2. The article opens and closes with descriptions of two news reports, each _ one major point in contrast with the other.A. makes B. made C. is to make D. making解析： 因为一个英文句子中只能有一个谓语，所以只能选择答案中不是谓语的，故排除A, C。叙述的观点是相反的，修饰成分descriptions of two news reports与被修饰成分each_one major point in contrast with the other之间的关系是主动的，所以用表示主动关系的ING形式，不用表示过去、完成的made。3.
