1、课时作业(九)Unit 3Section Developing ideas, Presenting ideas & Reflection阅读理解ASurrounded by the sea off the coast in MidNorway, there is an island called Myken. This small island has about ten permanent residents, and for more than 50 years has been supplied with electricity via a 32kilometre undersea ca
2、ble (电缆). A break that appeared in the cable last autumn resulted in two months without power, so the island community started looking into a better way of sourcing their electricity. “Myken is far out at sea, so as far as possible it should be taking care of things itself,” says Trude Tokle, who is
3、 the project manager of Mykens energy project. “This is why we want Myken to become entirely selfsufficient in energy. It is also important to take the environment into consideration,” she says. Many point to the idea that the solution may lie in a hydrogen (氢) plant, specifically tailored for small
4、 islands. The “raw materials” for hydrogen production come from nature itself in the form of the sun and wind, Researchers have calculated that energy costs will be lower by using hydrogen production than the undersea cable option. And it is possible to store energy in the form of hydrogen for longe
5、r periods. This means that supplies will not have to rely on a lot of expensive batteries or external energy sources, even during periods when the sun isnt shining, or the wind isnt blowing. The Myken project has attracted several technology companies. They are currently working on a pilot project.
6、The project involves experiments on the feasibility (可行性) of the hydrogen system in which electricity is generated from solar and wind sources. The electricity can be used immediately, but during periods when all the energy generated is not required, the spare energy can be used to split seawater in
7、to hydrogen and oxygen. The hydrogen can be stored in a tank, and used later to generate electricity. The pilot project will help researchers know more about how effectively the system will work in the hydrogen plant. Since the island has a distillery (酿酒厂), where the distillation (蒸馏) process relie
8、s on energy, a hydrogen plant on Myken offers an even greater environmental benefit. Spare heat from the hydrogen system can also be used for the heating part in the distillation process.“In Norway alone there are about 300 islands inhabited all year round by small populations,” says Kyrre Sundseth,
9、 a hydrogen researcher in Norway. “All of these islands may be candidates for using this technology. In global terms were talking about 10, 000 similar islands.”1Why is a hydrogen plant suitable for Myken?AIt is perfect in size for small islands.BIt can send electricity to faraway places.CIt will re
10、store local natural environment.DIt provides green and sustainable energy.2What is mainly talked about in Paragraph 4?AThe study on the energy storage.BThe test on the hydrogen system.CThe experiment on the raw materials.DThe research on the innovation of the pilot project.3According to the passage,
11、 a hydrogen plant will _.Aproduce purified seawaterBprove more effective workCcontribute in more than one wayDbenefit from the distillation process4What does Kyrre Sundseth think of the project?APromising. BSystematic.CIrreplaceable. DTime saving.BHave you heard about Post Office Cats in Britain? Th
12、ey are mouse hunters. The post office has actually employed cats since 1868. They are not employed to sort or deliver mail, of course, but to protect the mail and keep the population of mice under control. They make sure your morning post arrives free from damage caused by rats and mice. London post
13、 offices were the first to try out the experiment. Within a few months the population of mice had shrunk sharply. Other post offices all over the country were soon using cats in the war against rats and mice as well. Within ten years the pay of the cats was improved from one and a half old pence a d
14、ay to six or nine pence a day. Now the average rate of pay is about a few pounds a month. Some of the hardworking cats have become quite famous. In 1980, a cat named Lucky stopped an attempted robbery in a Worcestershire post office on her own. As the two burglars made their way in through the windo
15、w, Lucky started an attack and they fled emptyhanded. Another excellent cat was Jerry of the Earls Court post office in London. He served the building for 16 years and was on duty for 24 hours every day. He drove all the mice away. However, there are fewer cats employed by the post office than at an
16、y time in the past. With the faster movement of the mail and better surroundings, post office cats are not always needed. But many post offices still employ them and they become great friends with the postmen. According to the post office, there is no plan for their services to be discontinued in th
