The government of prefix = st1 /Norwayis planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world's food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the NorwegianislandofSpitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth. An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, "the worst came to the worst". Norwayis expected to start work next year. The project is expected to cost three million dollars. Workers will drill deep in the side of a sandstone mountain. Temperatures in the area never rise above 0oC. The seeds will be protected behind concrete walls a meter thick and high-security door. The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0oC. The cold weather would protect the seeds even if the air could not be replaced. Mr. Fowler says the proposed structure will be the world's most secure gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norwayfirst proposed the idea in the 1980s. But security concerns delayed the plan. At that time, the Soviet Union was meeting inRomeof the Food and... We can infer from the text that _ . A) People will get newly-developed seeds from the center every year B) The storage center will greatly promote world agriculture C) Norway had meant to build the storage centre about 20 years before D) There haven't been any seed storage centres in the world before

Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease. Which of the following animals hasn't been seen for over a century? A) Rio Pescado stubfoot toad. B) Gastric brooding frog. C) Turkestanian salamander. D) Scarlet frog.

Ques:Australia is famous for its beautiful beaches. And Australian people love swimming and going to the beach. But it wasn't always that way. Different Climate, Different habits When Europeans first invaded Australia, the only people here who were good at swimming were the Aboriginal people. The Europeans came from climates where it was too cold to swim. Also some people worried that they would get sick if they wet their whole body. However the warm climate of Australia soon changed their attitude to swimming. At first, only men swam. They swam naked - there were no women to see them. Cover up! By the 1880's and 90's visiting the beach was very fashionable and a lot of people went there, especially in warm weather. They wore everyday street clothes - much more than people wear at the beach today. In those days, people believed they should cover most of their body so it would not be seen by the opposite sex. Special bathing costumes were designed for women. These costumes used a lot of cloth and were very heavy when wet, making it difficult to swim. Laws Made and Laws Changed The government decided to stop men swimming naked.It passed a law which forbade bathing between 6am and 7pm. Many people objected to this law and wrote letters to the government asking it to change the laws. In 1903, the laws changed; people could swim in the daytime, but they had to wear neck-to-knee costumes. The Shrinking Costume As time passed, swimming costumes became smaller and more convenient. At first men and women were covered from neck to knee. Then the arms became bare. Then more of the legs were uncovered.Each new change was regarded by many as shocking and rude and people wrote letters to the newspapers complaining about the new costumes. Nowadays some people go to special "nude beaches" to swim naked. However, most people cover their bodies more than they did ten years ago -- not because they think bare skin is shocking -- but to protect their skin from the harmful rays of the sun. According to the law just before1903, people must _ . A) not swim in the main daylight hours B) only swim between 6am and 7pm C) have a bath at 6am and 7pm D) swim with neck-to-knee costumes between 6am and 7pm
