题型：不详难度：来源：

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 (埋葬) it in the garden and wait for it to flower（开花）. A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. 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 poisonous（有毒的）chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed .When this new type of cover turns into waste, it forms nitrates (硝酸盐). These feed the seed and help the flower grow. Engineers have designed a small transparent (透明的) 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 cover so far. But we are working with scientists 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（不断）throwing their mobiles away. This means producers 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 change this, according to the scientists.

小题5:B

解析

试题分析：这篇文章讲的是随着科技的发展，一种新型手机将要问世，这种手机的外壳能解决手机的浪费和污染问题。
小题1:细节理解题。根据文中原句When you have finished with your mobile phone you will be able to bury (埋葬) it in the garden and wait for it to flower（开花）. （当你用完你的手机后你就能把它埋在花园里然后等着它开花）可知此题答案是B。
小题2:细节理解题。根据提供的信息及原句They have made sure it only grows when the phone is thrown away.（他们确保（种子）在手机扔了时才生长）可知D的描述是错误的。
小题3:推理判断题。根据文中最后一段描述一种新型的手机壳可减少对环境的破坏，故选A。
小题4:推理判断题。这种研究在进行是因为手机用户不断的扔掉手机，对环境造成和大的破坏，所以选B。
小题5:推理判断题。从文中信息可获知这种新型手机既环保又实用，所以一定会卖的很好，故选B。
