Unit 3 Under the sea也许这个星球上最未被开发的地区是海底，因为那里太深了，以至于我们无法详细研究。即使人们对海床进行商业开采，它仍是一个未知数。上层和中层水域的海洋生物都很容易记录，不过深海环境仍然深藏着很多秘密。探讨这些领域是困难的，因为海底深处有巨大的压力。目前我们还无法制造出能在深海正常工作的机器。当我们能够做到这一点时，我们将会发现一个全新的海洋世界。科学将揭示更多的深海秘密。参考词汇：未被开发的地区 unexplored area; 详细研究 search in detail; 商业开采 business exploration; 上层和中层水域 the upper and middle waters 【写作要求】 只能用 5 个句子表达全部内容。Perhaps the most unexplored area on this planet is under the deep sea, which we have never been to, because they are too deep for us to search in detail. Although we do have business exploration of the sea bed, the deep sea is still unknown. The environment of deep sea can still keep many secrets, though the marine life of the upper and middle waters are fairly well recorded.To explore these areas without special machines is difficult because of the great pressure deep down. When this could be done with machines, scientists will enable us to find out more secrets of deep sea one day. 1. adj. 每年的 n. 年刊；年鉴 2. n. 目击者；证人；证据 vt.目击 3. vi. 大叫；呼喊 n. 叫声；喊声 4. vi. & n. 暂停；中止 5. n. 协作；配合 6. vt. 拖；拉；扯 7. n. 深(度)；深处 ____________________ ____________________ ____________________ ____________________ ____________________ ____________________ ____________________annual witness yell pause用心 爱心 专心1 teamwork drag depth8. vt. 催促；极力主张9. vt. 放弃；遗弃；抛弃10. n. 关系；血缘关系；交往 11. vi. 慢跑 vt. 轻推；轻撞 12. n. 网；网状物；网络 13. n. 目标；靶；受批评的对象 14. vt. 反射；思考 vi. 思考 ____________________ ____________________ ____________________ ______________...
