Passage 2
As the __11__ of life continues to increase, we are fast losing the art of relaxation. Once you are in habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.

The amount of stress a person can __15__ depends very much on the individual. Some people are not afraid of stress, and such characters are __16__ prime material for managerial responsibilities.

In fact we make choice between "fight" or "flight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so __18__ , but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued __19__ to stress, that health becomes endangered.

Passage 3
In the early days of nuclear power, the United States make money on it. But today opponents (反对者 ) have so complicated its development that no nuclear plants have been ordered or built here in 12 years.
The greatest fear of nuclear power opponents has always been a reactor "meltdown". Today, the chances of a meltdown that would threaten U. S. public health are very little. But to even further reduce the possibility, engineers are testing new reactors that rely not on human judgment to shut them down but on the laws of nature. Now General Electric is already building two advanced reactors in Japan. But don't expect them even on U. S. shores unless things change in Washington.
The procedure for licensing nuclear power plants is a bad dream. Any time during, or even after, construction, an objection by any group or individual can bring everything to a halt while the matter is investigated or taken to court. Meanwhile, the builder must add nice-but-not-necessary improvements, some of which force him to knock down walls and start over. In every case when a plant has been opposed, the Nuclear Regulation Commission has ultimately granted a license to construct or operate. But the victory often costs so much that the utility ends up abandoning the plant anyway.
