(时间：70分钟，分值：85分) UNIT 1　SCIENCE FICTION Using Language (2), Assessing Your Progress & Video Time 第Ⅰ卷(满分25分) Ⅰ. 阅读理解(共4小题；每小题2.5分，满分10分) Scientists in England are using two self­directed water vehicles to explore the animal and plant life of the Celtic Sea. The Celtic Sea is a body of water off the southern coast of Ireland. The area is known for its unusual sea life. Scientists want to know why sea creatures are so attracted to this part of the Atlantic Ocean. One of the research vehicles is powered by batteries. It collects information for the National Oceanography Centre in Southampton, England, and the World Wildlife Fund. The vehicle's low energy requirements permit it to stay floating on water for up to 30 days. Reports of what it finds in the Celtic Sea are sent by satellite. Stephen Woodward is an engineer who helped design the vehicle. He says the vehicle has equipment that can discover small organisms called zooplankton (浮游动物) and fish. He adds that other sensing equipment measures water currents and other features of sea life. The vehicle also creates a map of the sea. Another vehicle is powered by the sun and the wind. It can stay floating on water for months. The robotic vehicle sends information about the so­called biodiversity hotspots. A biodiversity hotspot is an area of an ocean that has a lot of plant and animal life activities. Lavinia Suberg is one of the scientists studying the Celtic Sea. She says productive ocean areas, like the Celtic Sea, attract zooplankton. The zooplankton then attracts fish. She adds that areas with a large increase of fish often attract sea mammals and birds. Using these robotic ocean vehicles greatly reduces the cost of exploring the sea with manned laboratories. Scientists can spend more time analysing the collected information. They say the research will give them a better understanding of the needs of the Celtic Sea for future management and protection. 【语篇解读】本文是一篇说明文。文章介绍了英国科学家利用水中机器人探索凯尔特海，旨在弄清楚为什么有如此多的动植物
