   Scientists say a huge percentage of bird species are in danger because their habitats，or homelands，are disappearing.Traditional migration paths take birds through countries that are mot protecting locations to stop.rest and feed，The scientists studied the migration，or fight，paths，of almost 1.500 species.They decided that 91 percent of then passed through dangerous areas.
     The major danger for migratory birds is development.Building and paving have covered over nature where birds stop and feed as they move from one part of the world to another，F(xiàn)or example，a bird called the bar- tailed godwit migrates from its breeding grounds in the Arctic.It flies all the way to the southern hemisphere in Australia and New Zealand，Along the way.the small binds stop at Yellow Sean mudflats in China.Korea .
      One of the scientists working on the study Says"many of these critical sites have been lost to land reclamation（開墾）owing to urban，industrial and agricultural expansion." The problem，according to investigators，is that many of these small birds die along their migration because they don't have a safe place to eat and rest.There is no place to restore their energy for the next leg of their journey."They simply perish（死亡）along the way，"says one of the scientists Countries in North Africa，Central Asia and those along the coasts of East Asia are having the most difficult time conserving land ，The scientists say these countries do not have enough areas that are safe for birds.
   The researchers say countries need to work together and provide safe stopover areas for birds that pass through their boundaries.For example，one country might have preserved safe zones for migrating birds.But a neighbor country might not.A bird might perish.One scientist tells the Los Angeles Times that while some habitats are changing，more work can be done to make urban areas safe for birds.He says small changes-like planting more native plants or keeping cats out of areas birds would be likely to use-could make a big difference.

    Environmental problems are becoming more and more serious all over the world.For example，cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories.Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore，wherever we go today，we can find rubbish carelessly disposed（處理）.
    There are different kinds of pollutants，each of which comes from different sources.It is necessary to identify the source of pollution，in order to make a policy to get rid of them.Different products，processes and activities of our industrialized world together form the major source of pollution.
    The forms of pollution can be mainly divided into three kinds-solids，liquid and gas.These pollutants have greatly damaged our planet and continue to do so.In fact，pollution is threatening our existence.The whole ecological balance of the earth is changing.Massive destruction of environment has brought about negative effects and even posed a great threat to man's existence.
    We must face the situation that exists and take action to solve our environmental problems.For instance，new laws must be passed to place strict control over industrial pollution；the public must receive the education about the danger of pollution and raise their awareness of protecting the environment and so on.
    The earth is our home and we have the duty to take care of it for ourselves and our later generations.Fortunately，more and more people have realized these problems.Measures have been taken to deal with these situations by the government.And laws have been passed to stop pollution，I hope the problems will be solved in the near future and our home will become better and better.

   It was the old lady's birthday．She got up early to be ready for the post．From the second floor flat she could see the postman when he came，and the little boy from the ground floor brought up her letters on rare occasions when anything came．
   Today she was sure there would be something．Myra wouldn't forget her mother's birthday，even if she seldom wrote at other times．Of course Myra was busy，and she herself had got a medal for her work for the aged．The old lady was proud of Myra．And Myra had been to see her mother three times since two years ago．
   The old lady was eighty today．She had put on her best dress．Perhaps Myra might come．After all，eighty was a special birthday．Even if Myra did not come，she would send a present．She was excited，like a child．
   Mrs．Morrison had cleaned the flat，and she had brought a bunch of flowers when she came to do the breakfast．Mrs．Grant downstairs had made a cake．Little Johnnie had been up with a packet of mints，and said he wouldn't go out to play until the post had come．
   "I guess you'll get lots of presents，"he said．
   What would it be？A pair of slippers，a table lamp，or a travel book？She stood by the window watching．The postman turned round the corner on his bicycle．Her heart beat fast．
   Johnnie knocked at her door． "Granny，granny，"he shouted， "I have got your post．"
   He gave her four envelopes．Three were unsealed cards from old friends．The fourth was sealed，in Myra's writing．The old lady felt a sudden feeling of disappointment．
   Almost reluctantly she tore the envelope open．Folded in the card was a piece of paper．Written on the card was a message under the printed Happy Birthday-Buy yourself something nice with the cheque，Myra．
   The cheque dropped to the floor like a bird with a broken wing．Slowly the old lady picked it up．With trembling fingers she tore it into pieces．
