Dear Mr President ,
I am writing to you about the problem of fish catching in the

In recent days , many people have come here to catch fish .
The problem is that they use electricity to catch fish . This has
caused damages . A lot of small fish have died and have been
floating in the lake . Besides, some other animals such as frogs ,
toads and small birds have died from electric shock waves .
I would suggest that you should have the lake cleaned,
prohibit and fine heavily anyone catching fish in this way . If
not , I am afraid all of the fish in the lake are not going to
exist in the near future .
I look forward to hearing from you and seeing your resolution
to this important matter as soon as possible with a view to
protecting the environment .
Yours sincerely

IV_Homework : 1
Are you looking for a cheap , clean , effective source of

power that doesn’t cause pollution or waste natural resources ?
Look no further than solar energy from our sun . At present ,
most of our electricity comes from the use of coal , gas , oil , or
nuclear power . This power could be provided by the sun . One
percent of the solar energy that reaches the Earth is enough to
provide power for the total population .
Many countries are already using solar energy . Solar panels
are placed on the roof of a house and the Sun’s energy is used to
heat water . The energy can be stored for a number of days , so
on cloudy days you can use solar energy too .
Sweden has an advanced solar energy program . There ,
all buildings will be heated by solar energy and cars will use
solar power instead of gas by the year 2015 .
