The most pressing nuclear energy issue is the disposal of nuclear waste. Even if all the reactors in existence were completely safe to operate, there would still be unsolved issue of what to do with the waste from generating electricity by means of nuclear energy.

Seven states, including California, have put the building of nuclear plants on hold until legislators are convinced that there is a safe way to dispose of the radioactive waste from the plants.

Since 1962, the volume of radioactive waste produced by the nuclear power industry has amounted to about 4,300 cubic meters. By the end of the twentieth century, if production continues at the same rate, there wil

[单项选择]Questions 62 to 66 are based on the following passage.
For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的)“drives” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.

BRITAIN’S universities are in an awful spin. Top universities were overwhelmed by the 24% of A-level applicants with indistinguishable straight As newer ones are beating the byways for bodies.

[单项选择] Questions 57 to 61 are based on the following passage.
Some families in America and elsewhere have started buying child friendly mobile phones outfitted with GPS (Global Positioning System) technology.
