问题                     "Cleverness" Charged Barbed Wire Net
    Current Group, a Germantown-based technology firm, has taken over an ordinary looking house in Bethesda and turned it into a laboratory tor smart-grid technology, the system the company believes will bring the nation’s electricity grids into the digital age.
    In the front yard stands a utility pole hooked up to a special transformer that connects the power lines to high-speed Internet. Hundreds of sensors attached to the lines monitor how power flows through the home That information is then sent back to the utility company.
    The process lets a utility more efficiently manage the distribution of electricity by allowing two-way communication between consumers and energy suppliers via the broadband network on the power lines. Based on data they receive from hundreds of homes, utilities can monitor usage and adjust output and pricing mresponse to demand. Consumers can be rewarded with reduced rates by cutting back on consumption during peak periods. And computerized substations can talk to each other so overloaded circuits hand off electricity to those that axe not fully loaded, helping to prevent blackouts.
    Some utility companies have launched initiatives to give consumers data about their energy consumption habits in an effort to lower energy bills. Smart-grid technology takes such programs further by automating electricity distribution, which would make grids more reliable and efficient.
    By partnering with utilities, the company hopes to tap into $4. 5 billion in stimulus grants intended to encourage smart-grid development. When he announced the funding, President Obama pointed to a project in Boulder, Colo. , as an example of a successful smart-grid experiment. Current is one of the companies working on the project.
    Current’s chief executive Tom Casey believes the technology will help utility companies better distribute electricity produced by renewable resources, such as solar panels or wind farms. "A smart grid’s system can be paired up with the renewable resources so that when the renewable source is varying, the overall load can be varied as well," Casey told the House Select Committee on Energy Independence and Global Warming. "This will re-dace or eliminate the need for backup coal or gas-based power generation plants. "
What does the phrase "tap into" ( Line 2, Para. 5 ) mean?
选项 A、To spend money like water.
B、To organize a smooth money flow.
C、To take advantage of the government money.
D、To absorb the money from shareholders.
答案C
解析 语义理解题。由题干中的tap into定位到第五段前两句。由第二句可知，奥巴马总统宣布了这一基金计划，也就是说，这笔钱是政府投入的资金，故[C]“利用政府的钱”为正确答案。[A]“花钱如流水”、[B]“让金钱通畅流通”和[D]“从持股人手中获取金钱”与本词组在原文中的意思不符，故排除。
