noise levels at all points to acceptable values. Some combination of methods is 
probably necessary. If all aircraft were made quieter by existing methods, there 
would be a number of economic benefits. An increase in airport capacity would 
occur. Property values near airports might rise. Transportation costs to and from 
airports could be reduced since the airports now could be located closer to 
population centers. Much research still needs to be done on the economic aspects 
of noise reduction and noise effects. Although some of the effects of noise 
pollution are known, more must be discovered about its effects on health, 
productivity, property values and the quality of life. Furthermore, the cost of 
noise pollution control to the economy as a whole needs to be investigated. The 
public must be alerted to the dangers and economic costs of noise pollution so 
that people may make intelligent choices and exert appropriate pressures.

Passage Two 
 Questions 26 to 30 are based on the following passage. During a state of deep 
relaxation, several physiological changes take place in the body：the body’s 
oxygen consumption is reduced；the heart beat decreases；muscle tension and 
sweating ease, and there is decreased sympathetic（交感的）nervous system activity. 
This restful state not only allows the body to repair and restore itself, but 
it has a calming effect on the consciousness. How to achieve this state of 
relaxation, however, is a matter of opinion, and in some medical circles, a matter 
of controversy（ 争论）. A recent report by Dr.David Holmes of the University 
of Kansas in the journal"American Psychologist"said that simply sitting in an 
armchair has just as many beneficial characteristics for the body as meditation 
（冥想）does. Researchers of other relaxation techniques disagree. These experts 
believe that more structured techniques, such as meditation, lead to a condition 
of deep relaxation. The debate goes on, but one thing appears to be clear: the 
relaxation response can be reached by a number of methods, and the methods 
themselves are not as important as getting there. One day, one method may work 
best；on another day, an alternative method may be more appropriate. Once you 
are aware of all the methods, you can find the one that works best for you. Some 
of the relaxation techniques are meditation, autoanalysis（自我心理分析）and 
progressive muscle relaxation. Although these techniques may not, in the end, 
produce more of a relaxation response than just sitting quietly in a chair, they 
have the added benefit of structure and discipline, and for these reasons appear 
to be more effective for most individuals. 
26.According to the passage, which of the following statements is NOT true when a person is in a state of deep relaxation? A、The body takes in less oxygen. 
B、The heart beats less frequently. 
C、Muscles become tense and the body sweats easily. 
D、The consciousness becomes more or less calmed. 
27.People seem to agree that ____________. 
A、sitting in  an armchair benefits a person as meditation does 
B、structured relaxation  techniques are more beneficial for a person 
C、to achieve a state of deep relaxation is possible through various means
D、what people are all struggling for is a state of deep relaxation 
28.In the third paragraph, the phrase"getting there"means 
____________. 
A、arriving at one’s destination 
B、getting what one wants most 
C、finding out a suitable relaxation technique 
D、reaching a state of deep relaxation 
29.As far relaxation is concerned, the author indicates that 
____________. 
A、aims are more important than means
B、means are more important than aims
C、more and more people are interested in relaxation techniques 
D、some relaxation techniques are better than others 
30.The author’s attitude toward relaxation discussed in the passage is
