美国科研人员对一种名叫虹鳉的淡水小鱼进行了长期观察研究．他们把天然的虹鳉鱼放养在一条瀑布的河流上游，该水域没有其天敌．而在瀑布以下的河流下游，也生活着天然的虹鳉鱼，这段河流中有其天敌．8年后，上游的虹鳉鱼发生了进化，在每一个生殖周期内将繁衍出数量更少、个头更大的后代，而下游虹鳉鱼这种变化并没有发生．

    Many other people and I in Britain love charity shops because we can find them on every street．The charity shops sell all kinds of things and they are very cheap．

    The first charity shop was opened by Oxfam in 1947．Now there are over 7,000 charity shops in the UK．My favorite charity shop in my hometown is the Cross Shop．There I always find children’s books，all 10 to 20 pence each．They are really cheap．

    Most of the shop workers in charity shops are volunteers，    each shop has a manager and he gets some money．Every morning you see bags of things outside the shops．Some people bring and put them there without waiting for thanks．In fact，over90％of the things in charity shops are from kind people．

    All the money the shops get goes to charity work．Charity shops raise more than 110 million pounds every year．The money is for sick and poor children。homeless and disabled people，and many others．In a charity shop you can get cheap but nice things．You might even feel special while shopping．

    If possible，let’s do something for charity together．
