阅读理解 A sunflower is a sunflower . A mobile phone is a mobile phone . But can you combine the two to do something for your local environment?As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (能进行生物递降分解的) mobile phone was, this month, introduced by scientists. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸钾). These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time, said one scientist.As phone technology is developing so quickly people are constantly throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it, said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.1.The main idea of the passage is ________ .A.the relationship between high tech and environmentB.the phone technology is developingC.phone can be turned into flowersD.mobile phone and environment2.The purpose of introducing a biodegradable mobile phone is ______ .A.to encourage consumers to recycleB.to prevent consumers from throwing their phones awayC.to meet consumers’ needD.to help consumers know which flower can best perform3.What is the possible meaning of the underlined word ?A.pleasantB.poisonousC.usefulD.new4.Which of the following statements is NOT true ?A.Engineers have designed a small transparent window to hold the rose seed .B.Mobiles with biodegradable covers can do good to nature .C.Manufacturers are under pressure to find ways of recycling mobiles .D.The flower only grows when the phone is thrown away .
