28、 B.belowC.upD.above解析：解析：第 1 段开宗明义，全球变暖导致粮食减产。第 2 段第 1 句跟第 3 段第 1 句类似，均举例说明某些国家粮食减产。所以此处要选一个说明减产的词，所以选 A 项 off，作副词时可表示“变少，变小”。(6).【C6】（分数：2.00）A.assumedB.thoughtC.guessedD.expected 解析：解析：根据第 l 段第 1 句的提示，粮食产量低于预期，而第 3 段第 1 句是其中一个例证，所以此处要填一个过去分词，表示预期产量，故选 D 项 expected“预料，预计。期待”。(7).【C7】（分数：2.00）A.volu
