Unit 7 The Sea你喜欢大海吗？阳光照耀下她妩媚多姿；狂风暴雨下她凶猛狂暴，除此以外你还了解大海的什么呢？When you look at the map of the world you will find there is more sea than land． The sea covers three quarters of the world． The sea is also very deep in some places． It is not deep everywhere． Some parts of the sea are very shallow(浅的)．But in some places the depth of the sea is very great． There is one spot，near Japan，where the sea is nearly 11 kilometers deep！The highest mountain in the world is about 9 kilometers high． If that mountain were put into the sea at that place，there would be 2 kilometers of water above it! What a deep place! If you have swum in the sea，you know that it is salty．You can taste the salt． Rivers，which flow(流动) into the sea, carry salt from the land into the sea．Some parts of the sea are saltier than other parts． There is one sea，called the Dead Sea，which is very salty． It is so salty that swimmers cannot sink！Fish cannot live in the Dead Sea! In most parts of the sea，there are plenty of fishes and plants． Some live near the top of the sea, others live deep down． There are also millions of tiny living things that float(漂浮) in the sea． These floating thingsare so small that it is hard to see them． Many fish live by eating these． The sea can be very cold． Divers who go deep down in the sea know this． On the top the water may be warm． When the diver goes downwards，the sea becomes colder and colder．Section ⅠWarmup & Lesson 1—Comprehending[基础词汇]1．sign n．手势；符号2．underwater adj．在水下，供水下用的3．voyage n．航海；航空4．persuade vt．说服，劝服5．presentday adj．当今的，现代的6．deed n．行为，行动[拓展词汇]7．participate vi．参加→participation n．参加8．evaluate vt．评估，评价→evaluation n．评估9．arrange vt．安排，准备→arrangement n．安排10．hunt v．打猎，猎杀→hunter n．猎人11．frightening adj．令人惊恐的，骇人的→frighten vt．使惊恐→frightened adj．惊恐的12．explorer n．探险家→explore vt．探险13．unknown adj．不知道的，未知的→known adj．已知的，闻名的14．eventually adv．最终，终于→eventual adj．最后的15．apologise vi．道歉→apology n．道歉1．fill__out 填写2．set__sail 启航3．according__to 根据，依照4．get__into__trouble 陷入麻烦，陷入困境5．make__it__to 到达6．in__search__of 寻找，寻求7．far__from 远离8．prepare__for．．．为……作准备1．The first．．．to do．．．The Vikings were the first Europeans to__reach__America(到达美洲的)．2．where引导的定语从句By around 900 AD，there were many places in Northern Europe where__the__Vikings__chose__to__live (有北欧海盗选择居住在那里)．3．现在分词作后置定语．．．there were as many as 10，000 Vikings__living__in__Iceland(生活在冰岛上)．4．find＋n．/pron．＋介词短语Biarni was hoping to join his father who was with Eric，but he was blown off course and__found__himself__in__an__unknown__land(发现自己在一个未知的地方)，from where he eventually reached Greenland．5．what引导的名词性从句Leif followed Biarni’s directions and sailed to what__is__believed__to__be(被认为是) the coast of presentday Canada．ⅠRead the text carefully and choose the best answer according to the text．1．The text mainly talks about ________．A．how the Vikings arrived in AmericaB．how Europeans settled in AmericaC．Columbus’ first discovery of AmericaD．the life story of Eric the Red2．Which of the following is TRUE about Eric the Red?

感顿市安乐阳光实验学校Unit 7 The SeaPeriod One Warmup & Lesson 1 The Spirit of ExplorersⅠ.阅读理解AUnder the world’s oceans and seas lies an attracting world of lands that stretches hundreds of kilometers in every direction.In this world，without the sun，there are deep canyons (峡谷)，great plains，and towering ranges of mountains.And this underwater world covers 70 percent of the earth’s surface.The world’s longest mountain range extends 16,000 kilometers under the Atlantic Ocean from Iceland to the Antarctic.Called t he MidAtlantic Ridge (山脊)，this range of mountains contains a number of high peaks，among them are the Ascension Island，the Azores，and Iceland.The world’s highest mountain is found in the midPacific area.It is the Hawaiian volcano Mauna Kea，which is 9,450 meters from base to peak.This is nearly 610 meters taller than Mount Everest.Only 4,221 meters of Mauna Kea rises above the surface of the sea.In 1873 the British survey ship Challenger discovered the deepest trench (海沟) in all the d the Challenger Deep，it is near the island of Guam and is 11 kilometers deep.Since sunlight only reaches to a depth of about 244 meters，many of the creatures of the deep sea live in a world of darkness.However，to get help in their survival，many have their own bright lighting system.Food comes to them from the upper levels of the ocean and they can get a constant supply from the waste matter that gradually moves downward toward the ocean floor.These undersea creatures must remain at the various places for which they are fit.To wander to other levels could result in death from improper water pressure.1．The best title for this text should be .A．The Sunless WorldB．The Longest MountainC．The Highest MountainD．The Deepest Trench答案A解析主旨大意题。

Unit 7 The Sea你知道海水为什么是咸的吗？它会不会变淡或者变得更咸呢？Have you ever noticed that，in the summer，when your sweat dries it will leave marks on your T shirt？ 1If you go to the seaside，you will know that seawater does the same to your clothes，because it also has a lot of salt in it.Water evaporates (蒸发) from the surface of the sea but the salt remains. Have you ever thought about whether the seas will keep getting saltier? The answer is no. The oceans have stayed at about 3.5 percent salt content for hundreds of millions of years. 2The outer hard crust of Earth is made up of a dozen or so hard plates that drift (漂流) on extremely hot，soft rock like floating islands on asea. The heat within Earth is not the same everywhere and the plates move due to the heat.When an ocean plate bumps into a land plate，the less dense land plate floats over the ocean one. The ocean floor gets pushed under，and its salty rocks，along with shells and bones，are lost deep within Earth.So， 3根据短文内容，从下面所给选项中选出能够填入空白处的最佳选项。
