LISTENING COMPREHENSION FROM UNIT 6 TO UNIT10
CLASS 9 ( HỌC KỲ II )
UNIT 6:
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 countries both developed and developing are guilty of doing this.
Secondly, Ships drop about six million 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 polluted the water but it also kill marine life.
Next, there are waste materials from factories without proper regulations, factory owners let the waste run directly into the river, 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:
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 this 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 the 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:











UNIT 9:
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 bookshelf. Block the rollers on your fridge and washing machine to prevent them from moving. Put hanging potted plants in plastic containers. Check the missions in your bathroom and bedroom. 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.

















UNIT 10:
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 on 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’s very cold. The temperature goes down to 151 0c below zero. But during the day the temperature rises to 100 o C 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 meter high.
And here is something very interesting to know the moon. You weigh one six of what you weigh on earth. If you weigh 50 kilos on the moon you will weigh only a little more than 8 kilos . You will be able jump very high even higher than an Olympic Champion. You can take very long steps as well. And may be you won’t sleep very well because one day on the moon lasts for two weeks
So is there life on the moon? I’ll leave the questions for you to answer yourself.
