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.[r]
(1)UNIT 6: THE ENVIRONMENT
Our oceans are becoming extremely polluted Most of this pollution comes from the land, which means it comes from people Firstly, there is raw sewage, which is pumped directly into the sea Many counties, both developed and developing, are guilty of doing this Secondly, ships drop about millions tons of garbage into the sea each year Thirdly, there are oil spills from ships A ship has an accident and oil leaks from the vessel This not only pollutes the water, but it also kills marine life Next, there are waste materials from factories Without proper regulations, factory owners let the waste run directly into the rivers, which then leads to the sea And finally, oil is washed from the land This can be the result of carelessness or a deliberate dumping of waste
_ UNIT 7: SAVING ENERGY
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, 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
UNIT 8: CELEBRATIONS
Auld Lang Syne
Should auld acquaintance be forgot and never brought to mind?
Should auld acquaintance be forgot and days of auld lang syne?
for auld lang syne, my dear, for auld lang syne,
we’ll take a cup of kindness yet, for auld lang syne
Should auld acquaintance be forgot and never brought to mind?
Should auld acquaintance be forgot and days of auld lang syne?
And here ‘s a hand, my trusty friend and gie’s a hand o’ thine

UNIT 9: NATURAL DISASTERS
If you live in an earthquake zone, you should take some time to look around your house Place heavy books on the bottom shelf of your bookshelves Block the rollers on your fridge and washing machine to prevent them from moving Put hanging potted plants in plastic containers Check the mirrors in your bedroom and bathroom Make sure they can’t move Don’t put your bed next to a window
Planning where you are going to be during an earthquake is very important The first thing to remember is to stay inside Then you should sit under a strong table or doorway, or stand in the corner of a room
(2)UNIT 10: LIFE ON OTHER PLANETS
Good evening Welcome to our Science for Fun Program This week we’ve received a lot of questions asking about life on the moon We’ve talked to some experts and this is what we’ve found out There is no water or air in the moon It is all silent because there is no air Of course there will be no music, no sounds There are no rivers and no lakes At night it is very cold The temperature goes down to 151oC below zero But
during the day the temperature rises to 1000C above zero.
There are great round holes on the moon They look like big lakes They are called craters There are more than 30,000 craters on the moon There are also high mountains The highest mountains on the moon are about 26,000 feet or 8,000 meters high
And here is something very interesting to know: on the moon you weigh one sixth of what you weigh on earth If you weigh 50 kilos, on the moon you will weigh only a little more than kilos You will be able to jump very high, even higher then an Olympic Champion You can take very long steps as well And Maybe you won’t sleep very well because one day on the moon lasts for two weeks
