工信部周三表示将加强对铝等有色金属的价格监测，防止过度投机扭曲市场。请看本报周五的报道：

China’s Ministry of Industry and Information Technology (MIIT) has pledged to strengthen its monitoring of the price of nonferrous metals such as aluminum in order to prevent excessive speculation that could distort the market.

In its annual review of the nonferrous metals sector, released Wednesday, the MIIT said it would work with nonferrous metals associations and relevant departments to help avoid speculation.

Shanghai aluminum prices have fallen by around 17 percent since September after a bull run during the first eight months of 2017 that saw the metal gain over 26 percent.

报道中的nonferrous metal就是“有色金属”，ferrous是“含铁的”，non-是表示否定的前缀，不含铁的金属就是有色金属，包括platinum (铂金), gold (黄金), silver (银), copper (铜), nickel (镍)等。
