[高考题型练习提能力] Ⅰ.阅读理解 About 97% of the world's water is salty and is found in our oceans and seas.But，as we can't 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 didn't 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。 1．Which of the following is the proper order of the food chain?

A．The use of international agreements. B．Forbidding fishing to protect fish stocks. C．The use of new techniques. D．Raising people's awareness of the need to protect oceans. B [细节理解题。根据最后一段第二句可知，很多国家限制鱼类的捕捞，而不是禁止，故B项不正确。] Ⅱ.阅读七选五 Winter is a really fun time of the year—it's great to have snowball fights and build snowmen. 1 When it's cold outside and you're not prepared，you can feel uncomfortable.Lucky for you，learning how to stay safe is not difficult. ● 2 Wearing thick clothes is the best way to stay warm in cold.Depending on where you live and how cold it is，some kids may need more clothes，some less. ● Take that hat.You maybe wear a large overcoat and ready to go，but are you forgetting something？ 3 You'll stay much warmer with a hat than without one—tons of body heat escapes right from your head.
