We must consider that of desires some are natural, others vain, and of the natural some are necessary and others merely natural; and of the necessary some are necessary for happiness, others for the repose of the body, and others for very life. Unhappiness comes either through fear or through vain and unbridled desire; but if a man curbs these, he can win for himself' the blessedness of understanding. Of desires, all that do not lead to a sense of pain, if they are not satisfied, are not necessary, but involve a craving which is easily dispelled, when the object is hard to procure or they seem likely to produce harm. Wherever in the case of desires which are natural, but do not lead to a sense of pain, if they are not fulfilled, the effort is intense, such pleasures are due to idle imagination, and it is not owing to their own nature that they fail to be dispelled, but owing to the empty imaginings of the man. The disturbance of the soul cannot be ended nor true joy created either by the possession of the greatest wealth or by honour and respect in the eyes of the mob or by anything else that is associated with causes of unlimited desires. We must not violate nature, but obey her; and we shah obey her if we fulfil the necessary desires and also the natural, if they bring no harm to us, but sternly reject the harmful. The man who follows nature and not vain opinions is independent in all things. For in reference to unlimited desires even the greatest wealth is not riches but poverty. Insofar as you are in difficulties, it is because you forget nature; for you create for yourself unlimited fears and desires. It is better for you to be free of fear lying upon a pallet, than to have a golden couch and a rich table and be full of trouble.

Another way to（16）nuclear waste is to send it into space, to the sun,（17）it would be burned. Other scientists suggest that this polluting material be（18）thousands of meters under the earth’s surface. Such underground areas must be free（19）possible earthquakes. Advances are being made. But it may still be many years（20）this problem could be finally settled. 1.

Sufficient buoyancy （浮力）to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage.Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious. The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster.Thus, the life preserver should be reversible that it is nearly impossible to get it on wrong.Catches, straps, and ties should be kept to a minimum.In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities.A suitable life preserver should also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim. 1.The passage is mainly about（）.
