passage 1 
     smoking, which may be a pleasure for some people, is a serious source of discomfort for their fellows. medical authorities express their   1   about the effect of smoking on the health not only   2   those who smoke but also of those who do not. in fact, nonsmokers who must involuntarily inhale the air polluted by the tobacco smoke may   3   more than the smokers themselves.
as you are doubtless aware, a considerable number of our students have   4   an effort to   5   the university to ban smoking in the classrooms. i believe they are entirely right in their aim.  6  , i would hope that it is possible to achieve this by   7   on the smokers to use good judgment and show concern for others rather than   8   regulation.
     smoking is prohibited by city laws in theaters and in halls used for showing films as well as in laboratories   9   there may be a fire hazard. elsewhere, it is up to your good sense.
     i am therefore asking you to maintain "no smoking" in the auditoriums and classrooms. this will prove that you have to keep nonsmokers' health and well-being   10  , which is very important to a large number of our students.

passage 2  
    it is difficult to imagine what life would be like without memory. the meanings of thousands of everyday perceptions, the bases _ 1   the decisions we make, and the roots of our habits and skills are to be  _2 _ in our past experiences, which are brought into the present  3__ memory.
memory can be defined as the capacity to keep __ 4   available for later use. it includes not only "remembering" things like arithmetic or historical facts, but also any change in the way an animal typically behaves. memory is __5__ when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. memory is also involved when a six-year-old child learns to swing a baseball bat.
memory   6   not only in humans and animals but also in some physical objects and machines. computers, for example, contain devices for storing data for later use. it is interesting to compare the memory-storage capacity of a computer   7    that of a human being. the instant-access memory of a large computer may hold up to 100,000 "words" — ready for   8     
use. an average american teenager probably recognizes the meanings of about 100,000 words of english. however, this is but a fraction of the total   9   of information which the teenager has stored. consider, for example, the number of facts and places that the teenager can recognize on sight. the use of words is the basis of the advanced problem-solving intelligence of human beings. a large part of a person's memory is in terms of words and   10   of words.
