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?
It may well be possible. When you have finished with your mobile phone you can bury it in the garden or a plant pot and wait for it to flower.
Recently, a biodegradable (可生物降解的) mobile phone was introduced by scientists. It is hoped that the new type of phone will raise consumers’ awareness of recycling.
Scientists have developed a new material in the past five years. It looks like any other plastic and can be hard or soft, and is able to change shape. It can also be broken down into the soil without giving off any poisonous chemicals. British researchers have 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 something that feeds the seed and helps 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 covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in the next time," said one scientist.
Which kind of flowers would perform best in the mobile phone?
选项
A、Roses.
B、Sunflowers.
C、Both roses and sunflowers.
D、It is still unknown to scientists and plant experts.
答案
D
解析
根据最后一段内容可知,科学家正在与植物专家合作,以找出哪些花表现最好。由此可推知,对于科学家和植物专家来说,哪种花在手机中表现最好仍然是未知的。故选D。
