[解析]
(1)C.推理判断题。根据第一段中的The experts desperately hope the "gold digger" will provide information on the locations of gold deposits (沉淀物) and make searching for the precious metal easier,and more environmentally friendly.专家们迫切希望"淘金者"能提供金矿的位置信息,使寻找这种贵金属变得更容易,更环保。由此可知,专家们希望获得更多关于携带金子的真菌的信息。故选C。
(2)A.推理判断题。根据第三段中Though fungi often interact with other things in nature,the reaction with gold was unexpected.虽然真菌经常与自然界的其他物质相互作用,但与黄金的反应是出乎意料的。及Dr.Bohu说的话But gold is so chemically inactive that this interaction is both unusual and surprising.但金在化学上是不活跃的,所以这种相互作用既不寻常又令人惊讶。再根据第四段中的"There is a biological benefit from this reaction." Dr.Bohu said, "Gold﹣loving fungi can grow faster and bigger to other fungi that don't work with gold.""这种反应有生物学上的好处。" Dr.Bohu说,"与其他不能与黄金共生的真菌相比,喜欢黄金的真菌可以生长得更快、更大。"由此可知,Dr.Bohu认为真菌与黄金的相互作用出人意料,但却是有益的。故选A。
(3)B.推理判断题。根据第五段中The researchers still need to conduct further analysis to understand the relationship between the fungi and the precious metal.More importantly,they need to determine if its presence is a sure sign of the existence of large deposits of the metal underground.研究人员仍然需要进行进一步的分析,以了解真菌和贵金属之间的关系。更重要的是,他们需要确定它的存在是否是地下存在大量金属矿床的确切迹象。以及最后一段However,those hoping to get free gold from the fungi are in for a disappointment,for the delicate fungus is hard to see.然而,那些希望从真菌中获得免费黄金的人注定要失望了,因为这种脆弱的真菌很难看到。可推断出,作者认为此发现尚需做深入的研究。故选B。
(4)B.标题归纳题。根据第一段的Humans are not the only ones that like gold.Australian scientists have discovered a new fungus (真菌) that decorates its long,thread﹣like tendrils (卷须) with gold collected from the soil.并非只有人类喜欢黄金。澳大利亚科学家发现了一种新的真菌,它用从土壤中收集的金子来装饰它长长的、像线一样的卷须。以及后文都是对该喜金真菌的描述,包括发现方式、发现分析及对其的科学展望等可知,标题核心词为gold﹣loving fungi(喜金真菌)。A项中核心词为beauty﹣loving fungi(爱美真菌),错误;C选项中核心词为gold mine(金矿),错误;D选项中核心词为gold with fungi(含真菌的金子),错误。故选B。
