* Read the text and do the tasks that follow.

There is only one ocean It is divided into five different parts: the Pacific,

Atlantic, Indian, Antarctic, and Arctic Oceans There are also many other

smaller seas, gulfs and bays which form part of them Altogether they

cover 75 percent of the earth’s surface For centuries, people have been

challenged by the mysteries that lie beneath the ocean However, today’s

scientists have overcome many of the challenges of the depth by using

modern devices They send submarines to investigate the seabed and bringsamples of marine life back to the surface for further study Satellite

photographs provide a wide range of information, including water

temperature, depth and the undersea populations If modern technology

did not exist, we would never have such precious information

Marine plants and animals fall into three major groups Some of them live

on or depend on the bottom like the starfish Some are swimming animalssuch as fishes and sharks that move independently of water currents whileothers are tiny organisms that are carried along by the currents like the

jellyfish Plants and animals of the sea, however small or oversized, all

contribute to its biodiversity were maintained,marine life would be at stake

Task 1 The words in the box all appear in the passage Fill in each blank with one of them There are more

words than needed.

1 Some plants and animals are referred to as ……… ……

organisms because they are extremely small.

2 Thanks to modern technology, scientists have been able to

… …… the life of plants and animals that live under the sea.

3 A ………… Is a large area of sea that is partly surrounded by

land

4 ……… is a term that refers to the existence of different

kinds of animals and plants which make a balanced

environment.

Task 2 Answer the questions

1 75% of the earth’s surface is covered by

the seas and oceans

2 By using modern devices

3 They help them to investigate the sea bed and

bring samples of the marine life back to the surface for further study

4 We can know a wide range of information

including water temperature, depth and the undersea population

5 Some of them live on or depend on the bottom (like the starfish.)
