There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C) and D). You should choose the ONE that best fits into the passage.
Is carbon dioxide the "villain" in the atmosphere? It is not very 31 and it is present in the atmosphere in so small a quantity —only 0.034 % —that it does us no 32 .
What’s more, that small quantity of carbon dioxide in the air is essential to life. Plants 33 carbon dioxide as their food, where it then serves 34 the basic component in all food consumed by animals. In the process, plants 35 oxygen, which is also necessary for all animal life. Here is what this 36 harmless but actually hazardous gas is doing to us:
The sea level is rising very slowly from year to year. 37 , it will continue to rise and do so at a greater rate in the 38 of the next hundred years.
39 , the sea will reach two hundred feet 40 its present level, and will be 41 the windows on the twenti-eth floors of Manhattan’s skyscrapers.
To 42 are two factors. First of all, in the last few centuries, first 43 , then oil and natural gas, have been burned for energy at a rapidly increasing rate. The burning produces much carbon dioxide.
44 , the Earth’s forests have been 45 , slowly at first, but in the last couple of centuries quite rapidly. Right now they are disappearing at the rate of sixty-four acres per minute.
46 , not only is more carbon dioxide being 47 to the atmosphere through the burning of fuel, but as the forests disappear, less carbon dioxide is being 48 from the atmosphere by plants.
The 49 of carbon dioxide in the atmosphere is steadily rising. With the Earth’s average temperature in-creasing, the polar ice caps are beginning to 50 , and the sea level is rising. Who is the "villain"? Carbon dioxide? Perhaps not.
