Read the passage and do the task 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 may of the challenges of the depth by using modern devices. They send submarines to investigate the seabed and bring samples 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 animals such as fishes and sharks that move independently of water currents while others 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. Unless this biodiversity were maintained, marine life would be at stake.
Task 1
The words in the box all appear in the passage. Fill each blank
with one of them. There are more words than needed
Some plants and animals are referred to as ....... organisms because they are extremely small
Thanks to modern technology, scientists have been able to.............. the life of plants and animals that live under the sea.
A .. is a large area of sea that is party surrounded by land
......... is a term that refers to the existence of different kinds of animals and plants which make a balanced environment
These scientists have collected different ............. to analyse for their experiment.

READ THE PASSAGE AGAIN THEN ANSWER THE FOLLOWING QUESTIONS
2. How do scientists now overcome the challenges of the depth?
1. What percentage of the earth’s surface is covered by seas and oceans?
3. What can submarines do to help scientists know about the undersea world?
6. What would happen if the sea biodiversity were not maintained?
4. What can we learn from the satellite photos?
5. What are the three groups of marine plants and animals?
