Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C) and D) on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Nuclear energy is seen as the new source of power for the future. Long ago 1 was thought that the atom was the smallest particle of 2 . About 60 years ago, 3 , scientists found that atoms of uranium, a sort of 4 like coal, could be split, and 5 make a lot of heat energy, 6 they were hit by large numbers of neutrons. After a lot of research, scientists found they could produce an even 7 amount of heat by splitting a 8 of atoms one after the other, in 9 is called a chain reaction. But this means that a lot of uranium is needed to 10 the fuel to produce the heat energy and the supply will 11 to an end soon. Fortunately, a new development could make uranium 12 in the production of nuclear power. There are certain types of atoms, 13 , when they hit each other 14 great speed, join together 5 of breaking apart, and it 16 produces energy. The material needed in this 17 can be found in sea-water, which covers more than three- 18 of the earth. Therefore, nuclear energy produced 19 this way could be the solution 20 the energy crisis.
