解析 词义辨析【直击答案】本空格所在句是…and that virtually all the__12 tested are the new swine flu,also known as（A）H1N1,not seasonal flu.本句是上文officials reported…另一宾语从句，空格后面的tested“经检测的”是所需填入词的后置定语，再联系本句信息“所检测出的都是新型猪流感，名为H1N1，并非季节性流感”可判断出本题答案为D项samples“样本”。【命题思路】本题考查相近含义名词的辨析，同时也要求考生对文章上下文逻辑正确理解。【干扰排除】A项examples“例子，榜样”具有强干扰性，其拼写和含义都和D项samples“样本，样品”有相似之处，但是不符合与所在句子的句意搭配。
