oceans and seas.but，as we cant drink sea water，how can it be important?every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths.most of the different species of animals and fish depend on simple plants for their food.these simple plants called algae(海藻)drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen.in fact，the algae produce over half of the oxygen people breathe.how important 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 by larger animals.these food chains are delicately balanced.the bad news about the food chains in the oceans is that they are under threat because of man.people once thought that the oceans were so big that it didnt matter if we dumped rubbish into them or caught huge quantities of fish and whales for food.but we now know this is not true and fish stocks in the oceans have started to drop.thankfully，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 to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution.finally，the importance of protecting oceans is being made known 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 an important part of the human diet.how important sea water is!【语篇解读】海洋对我们人类的生存起到至关重要的作用，但是人类在很长一段时间内对海洋造成了污染和破坏，现在各国都在努力采取措施保护海洋。1which of the following is the proper order of the food chain?asmall

dwhich【解析】先行词是表示地点的名词，但关系词在从句中作主语，所以用which。【答案】d3a.excited bpuzzledcsatisfied dconfused【解析】由于作者要和海豚一起游泳，所以对将要发生的一切感到非常“兴奋”(excited)。由于还没有发生，所以不能用“满意的”(satisfied)。【答案】a4a.crowded bclassifiedcdivided ddevoted【解析】根据下文的“每小组5、6人”判断，此处是把游客“分成”了小组。【答案】c5a.lecture bmeetingcargument ddiscussion【解析】根据常识可知，训练员在水池边给游客讲解注意事项，所以用lecture。【答案】a6a.caught btrainedcpractised dbought【解析】根据下文的“had been trained well”判断，此处指“训练”(train)海豚的人。【答案】b7a.however botherwisectherefore dbesides【解析】上文谈到海豚受到过良好的训练，下文说它们能够和我们一起做一些运动，是训练的结果，所以用therefore。【答案】c8a.protection bruleccare dcontrol【解析】根据上下文可以看出在训练员的控制下，海豚可以和我们做许多动作。under the control of意为“在控制下”。注意区分under the rule of“在统治下”。【答案】d9a.striking btouchingcbeating dhitting【解析】一开始是“抚摸”(touch)海豚。本段最后的“touch them”有提示，其余3个词都有“打”的意思。【答案】b10a.return bfearcturn dtrouble【解析】要抚摸海豚自然是一个接一个地，所以用in turn“依次；轮流”。【答案】c11a.looked bsearchedccared dwaited【解析】wait for.t
