《一》:Here is a page from a magazine named Future . Read the following about things that may happen in ten years .
Cars will run on solar power or electricity and will be much cleaner . They will be much safer.For example ,if you are too close to another car or if you are driving dangerously, your car will slow down by itself .
Because there won't be any srare land ,new cities will have to be built in the sea .Some cities on water will have two levels .Pepole will live on the upper level; the lower level will be used for traffic ,shops and factories .
Biotechnology will make food better and healthier.Plapts that are not affected by insects or illness will be developed ,The taste of fruit and vegetables will be better and food will be kept longer ,
New technology will be used to make TVs that are only 5cm thick ,They will have pictures that are as clear as photos.Electrical appliances will be quieter and will be controlled by computer ; they will also use 50% less power.
Many new ways to cure illness will be successful using products of genetic engineering(基因产品) Cures will be found for the flu and common cold .However,some new illness will appear.
《二》 : Thirty years ago ,Lake Ponkapog in Hartwell ,New Jersey ,was full of life .Many birds and animals lived beside the water which was full of fish .Now there are few birds,animals ,and fish ,The lake water is polluted .It is a colour of dirty brown, and it is filled with strange plants ,
How did this this happen.? First ,we must think about how water gets into Lake Phnkapog ,When it rains ,water comes into the lake from all around ,In the past ,there were forests all around Lake Ponkapog ,so the rainwater was clean .
Now there are many homes around the lake ,People often use chemicals in their gardens.They use other chemicals inside their houses for cleaning or killing insects .There are many bussinesses.Businesses use chemicals in their machines or shops .Other chemicals fall onto the ground from cars or trucks ,When it rains ,the rainwater picks up all the chemicals from homes and businesses and then carries them into the lake .They pollute the water and kill the animals.
Boats on the lake are also a problem ,Lake Ponkapog is a popular place for motorboats ,But oil and gas from boats get into the lake ,So more bad chemicals go into the water this way .
People in Hartwell are worried ,They love their lake and want to save it ,Will it be possible ?A clean lake must have clean rainwater going into it ,Clean rainwater is possible only if people are more careful about chemicals at home and at work .They must also be more careful about gas and oiland other chemicals on the ground .And they mustn't use motorboats any more on the lake ,All these may change people's lives.Only then can Lake Ponkapog be a beautiful, clean lake again .
