树上长不出钱，但是科学家已确定能够在一些植物的叶子中找到金子。澳大利亚的研究者称，通过桉树树叶的一些微粒能够定位地下数米深处的金矿。他们认为，这个发现为在复杂地形中采矿提供了新的途径。然而，叶子中的含金量非常少。来自澳大利亚联邦科学与工业研究机构的一位地球化学家称，“我们做过估计，需要500颗种植在金矿上面的树才能做一个金戒指。”但是，这些树之下30米（100英尺）处可能埋有真正的金矿。

Gold in Trees Leads to Hidden Deposits
Money might not grow on trees， but scientists have confirmed that gold is found in the leaves of some plants. Researchers from Australia say that the presence of the particles in a eucalyptus tree’s foliage indicates that deposits are buried many metres below. They believe that the discovery offers a new way to locate the sought-after metal in difficult-to-reach locations. The amounts of the precious metal were tiny. “We’ve done a calculation， and found that we need 500 trees growing over a gold deposit to have enough gold in the trees themselves to make a gold ring，” said a geochemist from Australia’s Commonwealth Scientific and Industrial Research Organisation （CSIRO）. However， the presence of the particles pointed to greater riches buried more than 30m （100ft） below.
