Part 2 写作衔接 写作 应用文 (说明文·海洋开发) 最近，你校同学正在参加校英文报组织的一场主题为“是否应该限制对海洋的开发”的讨论。请你用英语写一篇短文，反映讨论结果。 　We had a discussion about whether to exploit sea, which arrested the attention of all the teachers and students in the school. Most of us think it should be limited. First, the technology of developing marine resources is so immature that it causes serious destruction and waste of marine resources.Meanwhile, over-exploitation has caused great damage to the marine environment and ecosystem. However,opponents consider there is a need to extend the exploration of the sea and find new resources underwater, as the sea is in possession of abundant resources while there is a serious shortage of resources on the earth. In my opinion, we should continue sea exploration on condition that we take measures to protect the sea. After all, there is an inseparable bond between human beings and the ocean.
