         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 (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 consumers 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 toxic (有毒的) 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 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 (经常地) 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.

杨老实吃名菜

李德泽

    杨老实今年70多岁了,一生都是在农村偏僻的山旯旮里度过的,正宗的乡巴佬。

    近来,他儿子当了局长。在一个双休日,局长开着小车回老家,把他接到城里去享享福,报答养育之恩。

    乡间“茅屋出公卿”,杨老实自然高兴,也就随小车进了局长之家。

    局长对读高中的儿子说:“我没有空闲。你就陪爷爷到城里各个地方去逛一逛。爷爷老了,你把钱管好。他想吃什么就买什么吧。”

    于是,孙儿陪着杨老实逛街。中午,孙儿牵着爷爷的手,走进一家名菜大酒楼,在豪华的餐厅内入坐。服务小姐走来递给一本名牌菜谱说:“你们要吃什么菜,请点吧。”

    孙儿就说:“爷爷,你喜欢吃啥就点啥,我付钱就是了!”杨老实翻开菜谱一看,感到菜名很新鲜,一连点了5个菜。

    不一会儿,服务小姐就端菜上桌。杨老实一看,顿觉奇怪,就指着一个个细瓷盘子问是什么菜名。服务小姐也就指着一个个盘子甜甜地做了介绍。

    杨老实终于明白:“母子相会”,原来是凉拌的煮熟黄豆铺底,上面放着豆芽。“小二黑结婚”是在盘子里放了两个剥去黑壳的皮蛋。“青龙卧雪”是盘子里装点白糖,上面放一根青黄瓜。“走在乡间的小路上”,居然是红烧猪蹄,然后在四周镶一圈香菜。“一国两制”竟然是一盘煮花生米和炸花生米。

    杨老实望着菜,默然沉思:这些东西,也不过是我们乡下常吃的东西而已。城里有文化的人真聪明,取些怪好听的名字。

    服务小姐又送来一瓶酒,开瓶盖倒了两杯,放在他俩的面前,然后飘然而去。

    孙儿一边给爷爷拈菜,一边劝爷爷喝酒。杨老实喝了两口酒,感到不舒服道:“这是什么酒?怎样像潲水味呢?”

    孙儿笑着说:“爷爷,这是名牌啤酒,不太醉人,喝习惯了就好喽。”

    杨老实拈菜入口,皱着眉说:“这菜也少,味道也不合我的口。”

    孙儿接上话:“爷爷,如今不像以往那些年成了,图多填肚子。现在好多人都讲究玩味了,还都究档次哩!你多吃几次,习惯了就合口味了。”

    酒毕。孙儿说:“爷爷,再吃碗名牌‘羊拉面’吧?”

    杨老实心想:羊怎么拉面呢?稀奇。又是啥鬼名堂?我得看看。想到此,他就答道:“要得。”

    孙儿叫来服务小姐,立马就端来两碗“羊拉面”。杨老实用筷子一撬,竞没有一片羊肉,直问服务小姐是何道理。小姐灿然一笑说:“做面条的师傅姓杨。杨师傅有一手做面条的绝技,在食品技艺大赛上获过金奖,已成名人。以名人作广告,就将面条命名为‘羊拉面’喽。”

    杨老实听完,叹了两口气:“唉!唉!真会骗人。”

    吃罢。杨老实看见孙儿摸出三张100元钞票,买单结了账。他一下子头昏眼花,惊呼:“怎么这么贵哟!我们乡下要卖好多谷子才够哟!”

    孙儿劝道:“爷爷,你辛苦一辈子,爸让你享受享受!”

    杨老实愤然道:“我再也不来享口福喽!真是‘名菜’宰我们乡巴佬没商量。我还是回乡下去吃原汁原味的好!”
