[解析]
(1)A .细节理解题。由第一段第一句话"Stonehenge (巨石阵) may have been a prehistoric health center"巨石阵可能是史前的健康中心。所以最近巨石阵被认为是人们从健康不佳中恢复的地方。故A正确。
(2)C .推理判断题。由第四段第二句话the key reason that about 80 of them,each weighing up to 4 tons and a half,were dragged more than 150 miles from the Preseli Hills to Wiltshire.这是其中约80块重4吨半的蓝石从普雷舍里山被拖到威尔特郡150多英里的关键原因。所以推断出,一些巨大的青石并不是在巨石阵中产生的。故C正确。
(3)D .细节理解题。由最后﹣段最后一句话"The professors believe that he was a devoted religious person who was hoping to benefit from the curing powers of the monument.教授们认为他是一个虔诚的宗教人士,希望这个著名的建筑能治愈他的疾病。所以短文中生病的旅行者应该是一个希望治愈巨石阵能治愈他传染病的病人。故选D项。
(4)B .标题归纳题。通读全文尤其是第一段"Stonehenge (巨石阵) may have been a prehistoric health center rather than a site for observing stars or a temple in honor of the dead,scientists said yesterday.New evidence unearthed at the World Heritage Site in more than 40 years suggests that the monument was a place where the diseased and injured went in groups,seeking cures."科学家昨日表示,巨石阵可能是史前健康中心,而不是观察星星的场所或悼念死者的寺庙。40多年前在世界遗产遗址出土的新证据表明,这座建筑物是一个患病和受伤者成群结队寻求治疗的地方。这对读者来说是一个大的新闻。所以短文的最佳标题是"巨石阵:仍在产生新闻"。故选B项。
