Unit 3Under the sea课时作业Ⅰ.阅读A(2020·安徽省合肥市八校高三第一次联考)If you're a design enthusiast, you're sure to feel dizzy over these jaw-dropping pools.SkyPark Infinity Pool, Marina Bay Sands, SingaporeLocated on the SkyPark above Singapore's most famous hotel, Marina Bay Sands, this is the world's largest rooftop pool. Offering amazing views of the city's skyline, the pool is at least three times the length of an Olympic swimming pool. As visitors swim toward the edge, they face an illusion that they'll float into the skyline. It's quite a heart-beaten rush!The Red Pool, The Library Koh Samui, ThailandThis blood-red pool is perhaps one of the most special hotel pools on the list. Set against the backdrop of Koh Samui's Chaweng Beach, the fascinating colour isn't the result of using artificial dye. Rather, the mosaic tiles (马赛克瓷砖) of orange, yellow and red make the brilliant sight that is set among trees and an open-air library.San Alfonso del Mar Resort Pool, Region de valparaiso, ChileThe world's largest outdoor swimming pool gets its water directly from the sea. The pool uses a puter-controlled pump and filtration system. Located at Chile's San Alfonso del Mar Resort, this huge man-made pool is larger than 20 Olympic-size pools and holds approximately 250 million litres of water. It also holds the Guinness World Record for being the world's deepest (115 feet) pool.Y-40 Deep Joy, Hotel Millepini Terme in Montegrotto Terme, ItalyThe deepest hotel swimming pool in the world will make you feel like you're jumping into the sea! The Y-40 Deep Joy is a round-shaped pool that reaches a depth of an impressive 130 feet. The pool, which has special caves, ledges (壁架) and underwater viewing glass, was designed by well-known architect Emanuele Boaretto. It's meant for leisure dives, dive training and photo shoots.篇章导读：本文是一篇应用文。

选修7 Unit 3 Under the seaⅠ.阅读理解Saving our oceansYour MissionTeach oceanographers(海洋学者)with different specialties about other ocean specialties and thus create a better understanding of the ocean as a complete, diverse system.BriefingYou ve been invited to lead the International Oceanographic Conference in Oslo, Norway. Over one hundred of your fellow oceanographers will attend it. The problem is that,with so many different specialties in the field—from geological to biological oceanography—the oceanographers at the conference are finding it difficult to understand what their colleagues are studying,let alone to grasp the ocean as an entire,diverse system!Your job will be to give the opening speech at the conference outlining the general kinds of oceanography in a way that each type of oceanographers will understand. Then, you will assign different oceanographers to different projects and explain to them how best to work together.Family-x fileYounger Xpeditioners:Pick one project,and learn more about it through its photo gallery. Then, create a poster based on the animals and terrain(地形). Make sure to label each animal that you draw. Show your poster to your family and describe to them what you have drawn.Older Xpeditioners:Learn more about each of the projects:Where (in the ocean) would oceanographers go to study them? What animals might oceanographers study in the project? Which types of oceanographers would you assign for each project and how would they work together?Finally,think about the ways in which the different general kinds of oceanography might relate. Why is it important to look at the ocean as an entire system, rather than as distinct parts? How might looking at each separate part and the ocean as a whole impact conservation efforts? Practise your speech for the conference in front of your family.1. What is your mission according to the text?A.To save the oceans all over the earth.B.To attend the International Oceanographic Conference in Norway.C.To enter for an activity with one hundred fellow oceanographers.D.To help better understand the ocean as a complete, diverse system.2. Where can you get the detailed instructions in advance?A.From the leader of the conference.B.From Younger Xpeditioners.C.From the part of Briefing.D.From Older Xpeditioners.3.

1．What does the text mainly tell us?

[能力提升] Ⅰ.阅读理解 Alaska's Arctic lakes now freeze later and melt earlier in the year than in 1950, leaving them easy to suffer water loss from evaporation(蒸发) and possibly adding to local warming, a new study finds.The winter ice season near Barrow, Alaska, is shorter than in 1950, researchers reported Jan.30 in the journal The Cryosphere. Lake ice is also thinner each winter.The scientists surveyed 402 lakes on the North Slope, where permafrost (permanently frozen ground) and shallow lakes dominate the area.In 2011, the lake ice was 38 percent thinner than in 1950, and 22 percent fewer lakes froze through to their bottoms. “When we saw the actual numbers we were shocked at how dramatic the change has been，” lead study author Cristina Surdu, of the University of Waterloo in Canada, said in a statement.Surdu and her coauthors analyzed the changes in lakeice thickness and ice cover with satellite images and climate model simulations (satellite images are only available from 1991)． The climate models suggest the Arctic lakes froze almost six days later and broke up about
