[00:06.45]LISTENING
[00:09.20]1 Listen to the tape and fill in the correct information in the spaces below.
[00:17.37]1.Walk along the street of any major city,
[00:23.54]and you will see that the air you breathe is not very fresh.
[00:29.49]Air pollution is a serious problem in many of the world big cities.
[00:35.97]It is caused by cars and factories.
[00:40.23]We also pollute the air when we burn oil or coal for energy and heat.
[00:46.99]2.Oh,my,look at this, dead fish everywhere
[00:53.76] What happened?We used to be able to drink the water in rivers and lakes.
[01:00.84]But today,many rivers and lakes have been so polluted that the water is useless.
[01:07.19]Factories' and drainage have been polluting the water.
[01:11.94]We aren't taking good care of water.We use too much water and we waste water.
[01:19.39]What is more we pollute water.
[01:23.46]3.This beautiful mountain is one of the most popular places for people to visite,
[01:31.32]during holidays and festivals.
[01:35.40]Thousands of people come here to hike in the mountains forestes and valleies.
[01:41.93]Unfortunately the tourists leave a lot of rubbish behind,
[01:48.09]plastic bags,soda bottles and other things are thrown everywhere.
[01:53.14]Many tourists also pick flowers and demadge the trees.
[01:58.78]And the many hotels in restaurants beening built
[02:03.53]are having a negative affect on the environment,too.
[02:08.71]READING
[02:11.34]ARE WE ENDANGERED
[02:14.69]Steve Jones is an environmental expert
[02:19.52]who tries to keep animals and plants from becoming endangered.
[02:25.08]"We are not alone in the world.
[02:28.74]We human beings could not survive without all the plants and animals around us.
[02:35.30]We often talk about how important it is to take good care of ourselves and our planet,
[02:42.14]but we don't always do as we say,"
[02:46.30]Steve says as he takes us on a tour of Green Park in Birmingham.
[02:52.04]Many of the earth's plants and animals have already died out,
[02:57.71]and several other species are endangered.
[03:01.97]If we want to live a better life and have a bright future,
[03:06.83]we must learn to act in ways that do not harm other living things.
[03:13.07]If we know more about what causes endangerment,
[03:17.75]we may be able to take measures before it is too late.
[03:23.00]A species can become endangered for different reasons.
[03:28.17]Animals and plants must have a habitat,or home,which is comfortable and clean,
[03:35.82]and where there is enough food and other resources.
[03:40.87]They are all used to their environment;
[03:44.71]that is,they have learnt how to live successfully in their habitat.
[03:50.77]When the habitat of a species is changed or destroyed,
[03:56.33]the animal or plant has to either adapt to the change or find a new home.
[04:03.30]If this is not possible,the species becomes endangered.
[04:08.95]If a new species arrives,the animals and plants of the habitat must change again.
[04:16.10]If the new species is too strong or uses too much of the resources in the hatitat,
[04:23.55]some of the original species may become endangered.
[04:27.70]A species may also die out
[04:31.96]if humans or other animals use too much of a plant or kill too many animals.
[04:39.54]The good news is that there is a lot we can do to help.
[04:45.18]First of all,we need to learn more about animals,plants and the environment.
[04:52.02]Experts tell us that we need to think about what we can do
[04:57.80]to keep animals and plants from becoming endangered.
[05:02.55]Steve says that we can help by creating more space for animals and plants:
[05:09.39]"You can plant a tree or build a birdhouse.
[05:13.84]It is simple but useful."
[05:17.91]Steve also wants us to think about what we do:
[05:22.59]"Please don't pollute the environment.
[05:26.24]If we find out more about what we should do,
[05:30.40]we can help Steve and others like him keep animals and plants
[05:36.33]and ourselves--from becoming endangered
[05:41.16]INTEGRATING SKILLS
[05:47.51]Reading and writing
[05:50.75]Without air,water and sunlight there would be no living things.
[05:58.50]Because they are so important,
[06:02.76]ecosystems try to be very careful with these valuable resources.
[06:09.32]Human beings often throw away things they have used only once.
[06:15.80]In good ecosystems,resources are used many times.
[06:21.96]The waste of plants and animals will become food for another.
[06:27.92]In fact,nature is much better at recycling than we humans are.
[06:34.58]Maybe we should learn from nature and become better recyclers
[06:40.74]if we throw away too much,
[06:44.79]we may be throwing away our future.
[06:49.34]We all care about nature and the environment,
[06:54.69]but we may not always do everythings we could or should.
[07:00.65]Scientists who know a lot about the environment
[07:05.38]say that we should "Reduce,Reuse,Recycle and Respond".
[07:13.11]Let's see what that means.
