問題詳情

(43~45) There are a lot of things we don’t know about the ocean. Large parts of the ocean floor have never beenseen by anyone. People believe that it’s important to explore and learn more about these places. But how can we explore the bottom of the ocean? There is too much water pressure for our bodies to godown there. We need an ROV to explore it. An ROV is a machine that can move and take pictures underwater, and it is controlled by the people on the ship. It can work well under the water pressure at the oceanbottom. Some can even bring rocks from the ocean bottom up to the water surface for people to study. ROVscan help us learn more about our ocean world and help us take better care of it. * explore 探測; bottom 底部; pressure 壓力; control 控制; surface 表面
