Part Ⅱ Reading Comprehension (35 minutes)
Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Questions 21 to 25 are based on the following passage:
Every year 100 million holiday—makers are drawn to the Mediterranean.
With onethird 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. Eightyfive 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 wastetreatment 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.
