2、st of the different species of animals and fish depend on simple plants for their food. These simple plants 3 (call) algae(海藻)drift near the surface of the ocean and use sunlight to turn carbon dioxide and water 4 food and oxygen. In fact，the algae produce over half of the oxygen people breathe. 5 i

3、mportant sea water is!Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals，which are in turn consumed 6 larger animals. These food chains are delicately balanced.The bad news about the food chains in the oceans

4、is that they are under threat because of man. People once thought that the oceans were so big that it didn't matter we dumped rubbish into them or caught huge 7 (quantity) of fish and whales for food. But we now know this is 8 true and fish stocks in the oceans have started to drop.9 (thankful)，

5、the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions 10 (protect) fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally，the impo

6、rtance of protecting oceans is being made 11 (know) to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are 12 important part of the human diet. How important sea water is!Task 1: Fill in the blanks Task2: The pass

18、re making greater effort to study ocean currents (洋流) .Most do it using satellites and other high­tech equipment.However, ocean expert Curtis Ebbesmeyer does it in a special wayby studying movements of random floating garbage.A scientist with many years' experience, he started this type of

19、research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States.There were so many shoes that people were setting up swap_meets to try and match left and right shoes to sell or wear.Ebbesmeyer found out in his researches

20、 that the shoesabout 60，000 in totalfell into the ocean in a shipping accident.He phoned the shoe company and asked if they wanted the shoes back.As expected，the company told him that they didn't.Ebbesmeyer realized this could be a great experiment.If he learned when and where the shoes went int

21、o the water and tracked where they landed，he could learn a lot about the patterns of ocean currents.The Pacific Northwest is one of the world's best areas for beachcombing(海灘搜尋) because winds and currents join here，and as a result, there is a group of serious beachcombers in the area.Ebbesmeyer

22、got to know a lot of them and asked for their help in collecting information about where the shoes landed.In a year he collected reliable information on 1, 600 shoes.With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the

23、findings of their study.As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean.He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand.They

30、 with the air tank，the diver could end up stuck too far underwater to be able to get up in time to breathe.Also, divers have to avoid going down too far too quickly._5_Once you've had some training，though，you're ready to take a dive and explore a whole new world under the sea.AIf not，they ca
