43、basketball，volleyball，swimming 并列，也表示一种运动。 填空项 1:_ （正确答案：innocent）解析： innocent解析 空前的不定冠词 an和空后的名词 pleasure提示，本空所填词可能是以元音音素开头的形容词或名词(短语)。再结合空后的 but可知，本句的前后两个分句构成转折关系，后面说要看到体育运动(sports)的深层次含义。由此可知，前半句很可能是说体育运动似乎是一项很“单纯的”娱乐活动。 填空项 1:_ （正确答案：take up）解析： take up解析 分析句子结构可知，本空所在句缺少谓语，再结合空前的 they和并列连词 and后

44、面的 given知，本空应填动词(短语)原形。they 在此指上句的 sports，因此，本空所填词需要和空后的much media time构成合理搭配且符合此处的语义。 填空项 1:_ （正确答案：show）解析： shown解析 空前的 is和空后的介词 on提示，本空应填动词的分词形式。再结合空前的 bowl game competition，race，match 这些电视节目和空后的 television channel可知，所填词很可能要表达“播放”的含义。 填空项 1:_ （正确答案：devoting）解析： devoting解析 分析句子结构可知，本空所在句谓语成分不完整。空前

45、的 are提示，本空应填动词的分词形式，且能与介词 to构成固定搭配。 填空项 1:_ （正确答案：improve）解析： improve解析 空前的不定式符号 to和空后的名词 circulation提示，本空应填动词(短语)原形，且为及物动词。to 在这里表示目的，空后提到，人们会买体育赛事信息量大的报纸。由此可知，报纸用越来越多的篇幅报道体育赛事的目的很可能是为了“提高”报纸的发行量。 填空项 1:_ （正确答案：especially）解析： especially解析 本空所在句句子结构完整，结合本空所在位置可知，所填词应为副词。 填空项 1:_ （正确答案：enormous）解析： e
