Surrounded by the sea off the coast in Mid-Norway, lies 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 32-kilometer undersea cable (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 Kyrre Sundseth, who is a hydrogen (氢) researcher in Norway and also the project manager for Myken’s energy project. “This is why we want Myken to become entirely self-sufficient in energy. It is also important to take the environment into consideration,” he says.

Much points to the idea that the solution may lie in a Hydrogen plant, specifically tailored for small 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 longer 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 isn’t shining, or the wind isn’t blowing.

The Myken project has attracted several technology companies. They are currently working on a pilot project. The pilot 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 into hydrogen and oxygen. The hydrogen can be stored in a tank, and used later to generate electricity. The pilot 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 relies 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 island inhabited all year round by small populations,” says Kyrre Sundseth. “All of these islands may be candidates for using this technology. In global terms we’re talking about 10,000 similar islands.”

1.Why is a hydrogen plant suitable for Myken?

A.It is perfect in size for small islands.

B.It can send electricity to faraway places.

C.It will restore local natural environment.

D.It provides green and sustainable energy.

2.What is mainly talked about in Paragraph 4?

A.The study on the energy storage.

B.The test on the hydrogen system.

C.The experiment on the raw materials.

D.The research on the innovation of the pilot.

3.According to the passage, a hydrogen plant will ______.

A.produce purified seawater

B.prove more technically reliable

C.contribute in more than one way

D.benefit from the distillation process

4.What does Kyrre Sundseth think of the project?

A.Promising.

B.Systematic.

C.Irreplaceable.

D.Time saving.

Madagascar lies in the Indian Ocean off the east coast of Africa. The island is perhaps best known as the unique home of the lemur (狐猴）. But those lemurs live among some of the most rich and varied flora (植物群）in the world. And so threatened is that flora that British and Malagasy scientists were involved in a project to collect seeds from the island to be stored in a British seed bank. The project is being done by the Royal Botanic Garden in London. The botanist Steward Cable is head of the conservation center there and a frequent visitor of the island.

I mean Madagascar is well known as one of the top biodiversity hot spots in the world. It has perhaps 13,000 plant species. 90% of those are unique to the country, i.e. found nowhere else in the world. But also many species, many of those species are only found in small areas.　　　 And I would say that probably about 80% of the population are dependent on farming.

And a lot of their farming is slash and burn，shifting cultivation (耕作）where farmers have to move to a new patch of forest every year. They cut it and they burn it and they can grow dry rice or cassava for a year or so or two years at most.And the nutrients are gone and they have　 to move to a new patch of forest .And for centuries that would not have been a problem with the low population and with long periods of no farming but people returning after three or five years something like that ,then the forest became grassland. So we are losing many of those species in Madagascar, those unique species.

1.which of the following is the habitat of the lemur?

A.Madagascar B.Britain

C.An Indian island. D.The coast

2.Why do scientists collect seeds from Madagascar?

A.The lemur will die out without them.

B.The flora on Madagascar is in great danger.

C.The island will sink to the bottom of the ocean.

D.The British seed bank wants to make money from them.

3.What is the result of the way people farm?

A.Many farmers have lost their homes. B.The population is becoming smaller.

C.Some rare species are gone. D.The crops are poor in nutrition.

4.How does the author sound?

A.Hopeless. B.Enthusiastic. C.Optimistic. D.Worried.
