MTA outsources $235M Verrazano Bridge project to China    The agency says it could not find an American company capable of making the high-tech steel plates it wants, but critics say the decision came down to cheaper labor.
摘两句关键的：
According to the MTA, there’s not a steel plant in America that can produce the type of high-tech steel plate it wants — known as orthotropic design. (据MTA，美国没有一家钢铁厂能生产所需的高技术钢材--正交各向异性材。)
。。。。。。
Orthotropic design is rarely used in America because the bulk of U.S. bridges were built before the technology existed.(正交各向异性材在美国极少使用，因为美国多数桥梁建成于此技术存在之前。)
It would cost another $100 million to keep the project in America, the MTA said. (如果在美国国内采购，要多花1亿美元。)
