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)LISTENING UNIT : 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 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 : 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 UNIT : 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 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: 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 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 is very cold The temperature goes down to 151oC below Zero But during the day the temperature rises to 100oC 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 than an Olympic Champion You can take verylong step as well and … May be you won’t sleep very well because one day on the moon lasts for weeks So, is there life on the moon? I’ll leave the question for you to answer yourself ĐỀ THI HỌC KỲ 2010-2011 I LISTENING: Listen to the CD player times and write T (True) or F (False) to the following tatements: (2ms) Solar energy can be cheap and clean Most of our electricity now comes from nuclear power The solar energy that gets to the Earth cannot provide enough power for the world’s population Solar energy can be used on cloudy days All building in Sweden will be heated by solar energy in 2050 Solar energy causes pollution Solar panels are installed on the roof of a house to receive the energy rom the sun We can save natural resources by using solar energy II LANGUAGE FOCUS A Choose the best answer a, b, c or d to complete each of the following sentences: (2ms) is a tropical storm with strong winds a Snowstorm B arthquake c Volcano d Typhoon The baby laughed _ as she played with her toys a happy b happily c happiness d happier (2) We are really looking forward you again a to see b seeing c to seeing d for seeing Nam got wet _ he forgot his umbrella a because b so c and d therefore Choose the word that underlined part is pronounced differently from the others a bill b plumber c bulb d label Choose the word that has a stressed syllable differently from the others a considerate b humorous c generous d famous Lan is very tired _, she has to finish her homework before she goes to bed a However b.Therefore c Because d But I’ve lost my new pen I’ve _ it everywhere but I can’t find it anywhere a looked after b looked for c looked at d looked up B Rewrite each of the sentences, beginning as shown, so that the meaning stays the same: (1m) Study harder or you will fail the next exams - If _ The book is very expensive I bought it last Sunday - The book which _ III READING - Earthquakes: Ninety percent of earthquakes occur around the Pacific Rim, which is known as the “Ring of Fire” In 1995, a huge earthquake struck the city of Kobe in Japan A large number of people were killed when homes, office blocks and highways collapsed - Tidal waves: Tidal waves are the result of an abrupt shift in the underwater movement of the Earth In the1960s, a huge tidal wave hit Anchorage, Alaska The tidal wave traveled from Alaska to California! - Typhoons: When a tropical storm reaches 120 kilometers per hour, it is called a hurricane in North and South America, a cyclone in Australia, and a typhoon in Asia The word “typhoon” comes from Chinese: tai means ‘big’ and feng means ‘wind’, so the word ‘typhoon’ means ‘big wind’ - Volcanoes: We can usually predict when a volcano will erupt Mount Pinatubo, which is a volcano in the Philippines, erupted in 1991 It was the world’s largest volcanic eruption in more than 50 years Hundreds of people died, but thousands were saved because scientists had warned about the eruption * Read the passage carefully The write True or False statements: (1m) Most of the earthquakes in the world happen in the Ring of Fire _ The earthquake in Kobe in 1995 caused severe damage _ * Read the passage carefully Then answer the questions below: (2ms) Why people call the Pacific Rim “Ring of Fire”?
