ENVIRONMENTAL ACTIVISTS
Paul Watson is an environmental activist He is a man who believes that he must do something, not just talk about doing something Paul believes in protecting endangered animals, and he protects them
in controversial ways Some people think that Watson is a hero and admire him very much Other people think that he is a criminal
On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd However, they had a strange prey, instead of hunting for animals, their prey was a ship, the Sierra The Sea Shepherd found the Sierra, ran into it and sank it As a result, the Sierra never returned to the sea The Sea Shepherd, on the other hand, returned to its home in Canada Paul Watson and his worked thought that they had been successful
The Sierra had been a whaling ship, which had operated illegally The captain and the crew of the Sierra did not obbey any of the international laws that restrict whaling Instead, they killed as many
whales as they could, quickly cut off the meat, and froze it Later, they sold the whale meat in
countries where it is eaten
Paul Watson tried to persuade the international whaling commission to stop the Sierra However, the commission did very little, and Paul became impatient He decided to stop the Sierra and whaling ships
in any way that he could He offered to pay $25,000 to any one who sank any illegal whaling ship, and
he sank the Sierra He acted because he believed that he whales must be protected Still, he acted without the approval of the government; therefore, his action controversial
Paul Watson is not the only environmental activist Other men and women are also fighting to protect the Earth Like Paul Watson, they do not always have the approval of their governments, and like Watson, they have become impatient Yet, because of their concern for the environment, they will act
to protect it

Exercise 2
Tsunami is a Japanese word which means harbour wave and is used as the scientific term for seismic sea wave generated by an undersea earthquake or possibly an undersea landslide or volcanic eruption When the ocean floor is tilted or offset during an earthquake, a set of waves is created similar
to the concentric waves generated by an object dropped into the water Most tsunamis originate along
Trang 3the Ring of Fire, a zone of volcanoes and seismic activity, 32,500 km long that encircles the Pacific Ocean Since 1819, about 40 tsunamis have struck the Hawaiian Islands
A tsunami can have wavelengths, or widths, of 100 to 200 km, and may travel hundreds of kilometers across the deep ocean, reaching speeds of about 725 to 800 kilometres an hour Upon entering shallow coastal waters, the wave, which may have been only about half a metre high out at sea, suddenly grows rapidly When the wave reaches the shore, it may be 15 m high or more Tsunamis have tremendous energy because of the great volume of water affected They are capable of obliterating coastal settlements
Tsunamis should not be confused with storm surges, which are domes of water that rise underneath hurricanes or cyclones and cause extensive coastal flooding when the storms reach land Storm surges are particularly devastating if they occur at high tide A cyclone and accompanying storm surge skilled an estimated 500,000 people in Bangladesh in 1970 The tsunami which struck south and southeast Asia in late 2004 killed over 200 thousand people
Question 11 Scientifically, tsunami is the term for
A seismic sea wave B undersea earthquake
C undersea landslide D volcanic eruption
Question 12 What does the word “concentric” mean?
A Wavy B Having many centers
C Having a common centre D A ring
Question 13 Which of the following may be a reason for a tsunami?
A An inactive volcano B A landslide on the seashore
C An undersea earthquake D A storm
Question 14 What will happen when an object is dropped into the water?
A Volcaic eruption may be a consequence
B Some concentric waves will be generated
C There will be seismic activity
D Earthquake may happen
Question 15 What is the zone of volcanoes and seismic activity in the world called?
A The concentric wave B The tsunami
C The Pacific Ocean D The Ring of Fire
Question 16 What is the greatest speed of tsunami traveling across the deep-ocean?
A 200 kilometres an hour B 700 kilometres an hour
C 800 kilometres an hour D 150 000 kilometres an hour
Question 17 How high is the wave of the tsunami when it reaches the shore?
A 100 meters B 200 meters C Half a metre D Fifteen meters
Question 18 How are tsunamis capable of obliterating coastal settlements?
A They have tremendous energy due to the great volume of water affercted
B They are a metre high or more
C They travel hundreds of kilometers
D They can strike the shore fifteen metres high
Question 19 What killed an estimated 500,000 people in Bangladesh?
A A tsunami
B A cyclone and accompanying storm surge

Question 20 Which of the following is NOT true?
Trang 4A Tsunamis only occur in Asia
B A cyclone along with storm surge happened in Asia in 1970
C Storm surges are domes of water rising underneath hurricanes or cyclones
D Storm surges cause extensive coastal flooding
Exercise 3
Because of the severe drought which has continued this year, water rationing will go into effect on Monday Lawns cannot be watered with automatic sprinklers; driveways, porches, and decks cannot be hosed down You may water by hand, but only on even-numbered days Cars can be washed on Wednesdays only The city has hired a new drought patrol crew, which will be looking for offenders
If you are caught, there will be a $50 fine for the first offence and a $100 line for the second offence
We realize that this is strict but the drought has affected LIS dramatically We ask your cooperation in conserving water
Besides the drought rules, we ask that you be prudent in your household water use Turn off the faucet while you brush your teeth Take short showers, you might even consider turning off the water
as you soap up Don't wash dishes under running water, and when you wash your clothes, save the final rinse water to begin your next load Let's all work together to save our community's water
Question 21 What is the main problem the speaker is referring to?

C Reusing washing machine water D Taking baths instead of showers
Exercise 4
Today I’d like to begin a discussion on the problem of the heating up the earth First we’ll touch
on the relationship between fluorocarbons and the ozone layer You probably remember that the ozone layer is the protective shield around the earth It is important to all life, because it filters out harmful ultraviolet light from the sun Ozone itself, a form of oxygen, is regularly made by the action of the sun
in the upper atmosphere It is also regularly destroyed by natural chemical processes
The problem now is that too much of the ozone layer is being destroyed Scientists suspect that certain chemicals, such as fluorocarbons, are contributing to the depletion of the ozone layer And how
do we use fluorocarbons? The most common uses are in spray cans and cooling systems The chemical pollution from these fluorocarbons can account for some of the ozone losses that have been reported There are, however, new studies linking the sun itself to the depletion of the ozone layer We’ll go into that new study more next time
Trang 5Question 26 Who is the most likely speaker?
A A doctor B A mechanic C A professor D A chemist
Question 27 What is the speaker’s main topic?
C Air - conditioning systems D Fluorocarbons and the ozone layer
Question 28 What is the most important purpose of the ozone layer?
A Providing fluorocarbons B Shielding the sun
Question 29 What is the ozone layer made of?
A Fluorocarbons B Oxygen C Shields D Ultraviolet light
Question 30 What will the speaker probably discuss next?
A How to make air conditioners with fluorocarbons
B Harmful effects of ultraviolet light
C The makeup of the ozone layer
D The sun as a cause of ozone layer depletion
