        　　Questions 21 to 25 are based on the following passage:
        　　Every year 100 million holiday—makers are drawn to the Mediterranean. With
one third of the world's tourist trade, it is the most popular of all the
holiday destinations; it is also the most polluted.　It has only 1 per cent of
the world's sea surface, but carries more than half the oil and tar floating on
the waters. Thousands of factories pour their poison into the Mediterranean, and
almost every city, town and　village on the coast sends its sewage, untreated,
into the sea.
        　　The result is that the Mediterranean, which nurtured so many civilizations,
is gravely ill—the first of the seas to fall victim to the abilities and
attitudes that evolved around it. And the pollution does not merely keep back
life of the sea—it threatens the people who inhabit and visit its shores.
        　　The mournful form of disease is caused by sewage. Eighty five per cent of
the waste from the Mediterranean's 120 coastal cities is pushed out in　to the
waters where their people and visitors bathe and fish. What is more, most cities
just drop it in straight off the beach; rare indeed are the places　like Cannes
and Tel Aviv which pipe it even half a mile offshore.
        　　Not surprisingly, vast areas of the shallows are awash with bacteria and it
doesn't take long for these to reach people. Professor William Brumfitt of　the
Royal Free Hospital once calculated that anyone who goes for a swim in the
Mediterranean has a one in seven chance of getting some sort of disease. Other
scientists say this is an overestimate; but almost all of them agree that
bathers are at risk.　Industry adds its own poisons. Factories cluster round the
coastline, and　even the most modern rarely has proper waste treatment plant.
They do as much damage to the sea as sewage. But the good news is that the
countries of the Mediterranean　have been coming together to work out how to save
their common sea.
        　　21. The causes of the Mediterranean's pollution is ____.
        　　A) the oil and tar floating on the water
        　　B) many factories put their poison into the sea
        　　C) untreated sewage from the factories and coastal cities

        　　22. Which of following consequence of a polluted sea is not true according
to the passage?
        　　A) Bring up so many civilizations.
        　　B) Various diseases in the sea.
        　　C) It threatens the inhabitants and travelers.
        　　D) One in seven chance of getting some sort of disease swimming in the
sea.
        　　23. The word “sewage”refer to ____.
        　　A) poison B) waste C) liquid material D) solid material
        　　24. Why does industry do much damage to the sea?
        　　A) Because most factories have proper waste treatment plants.
        　　B) Because many factories have not proper waste treatment plants even the
most modern one.
        　　C) Because just the modern factory has a waste treatment plant.
        　　D) Because neither ordinary factories nor most modern ones have p roper
waste treatment plants.
        　　25. What is the passage mainly about?
        　　A) Save the world.
        　　B) How the people live in the Mediterranean sea.
        　　C) How the industry dangers the sea.
        　　D) Beware the dirty sea.
