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.
