分析本文报道了中国感染禽流感的情况，以及采取的措施和注意事项．

解答 61．have been reported 考查时态和语态．根据时间状语so far可以判断本句是一个现在完成时的句子，又根据主语 10human H7N9flu cases与report之间是被动关系，所以用现在完成时的被动语态．
62．on 考查介词．在英语表达中具体到某一天用介词on．
63．The 考查冠词．根据句意：最新的两例是在四月五号报道的，这里是特指，所以用定冠词the．
64．them 考查代词．这里指的是两例患者中的一例，所以用复数他们them．
65．is   考查谓语动词．另一例患者正在被治疗中，用现在进行时的被动语态is being treated，所以答案填is
66．environmental 考查形容词．根据句意：北京在六个农业区开展了环境试验．此处用形容词来修饰test，environmental是形容词"环境的"．
67．to occur  考查固定短语．be likely to do 是固定短语"有可能…"．根据句意：感染最有可能发生在冬季和春季．所以答案填to occur．
68．experts   考查名词．根据句意：疾病控制和预防专家说，H7N9病毒没有人与人之间传播．  expert是名词"专家"．根据谓语判断是复数形式．
69．（should） avoid   考查虚拟语气．suggest做建议讲引导的宾语从句用虚拟语气，谓语用should+动词原形，should 可以省略．所以答案填（should） avoid．
70．and 考查连词．专家建议，每个人都应避免接触死禽和活禽，只购买带有安全检验证书的家禽．根据上下句的关系，两句之间是并列关系，所以用and连接．
