问题 A sunflower is a sunflower. A mobile phone is a mobile phone. But can you【S1】the two to do something for your local【S2】?
It may well be possible. When you have finished with your mobile phone you will be able to【S3】it in the garden or a plant pot and wait for it to flower.
【S4】, a biodegradable(生物可降解的)mobile phone was introduced by scientists. It is hoped that the new type of phone will encourage【S5】to recycle.
Scientists have come up with a new material over the last five years. It looks like any other【S6】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【S7】. 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【S8】nitrates(硝酸盐). These feed the seed and help the flower grow.
Engineers have designed a small【S9】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【S10】to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.

选项
答案E
解析 该空应填入动词原形，选项中只有E、G和K是动词原形。文章前两句点明两者是截然不同的东西，这里用but一转，讲能不能把两者结合起来，E最符合文意。
