Many people believe the glare(炫目的光) from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of “snow light”.
The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on(聚集) in a broad space of snow-covered without-grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid(流体) which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts(侦察兵) ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark-colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snowblanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.
1．To prevent snowblindness caused by the strong light from snow, wearing glasses or not ________.
[ ]
A．depends on whether the snow is white enough
B．makes no difference
C．makes much difference
D．depends on whether the snow is thick
2．When the eyes are tired, tears flow out ________.
[ ]
A．to clear the vision
B．to make the eyes stop searching
C．to make the vision unclear
D．to produce more and more liquid
3．Snowblindness can be avoided ________.
[ ]
A．by moving one's gaze back and forth
B．by walking ahead and keeping looking around
C．by making up for the discomfort of one's eyes
D．by providing the eyes with something to focus on
4．What is the probable meaning of the underlined part “Their gaze is arrested” (in paragraph 3)?
[ ]
A．They get something to look at.
B．They can only look at one spot.
C．Their eyes are clear.
D．They can't see freely.
查看习题详情和答案>>When several different people look at the same person, it’s not unusual for each of them to see different things; when you alone observe one behavior or one person at two different times, you may see different things. The following are but some of the factors that lead to these changing perceptions(感知认可)
(1) Each person’s perceptions of others are formed by his or her own cultural conditioning education, and personal experiences.
(2) Sometimes perceptions differ because of what we choose to observe and how we deal with what we’ve observed. It is not necessarily true that person’s perception is based on observations of a particular person. Your observations may be totally controlled by what others have told you about this per??son; or you may focus (聚集) primarily on the situation or role relationship. Most people do not use the same yardstick (标准)to measure their parents, their friends, and strangers.
(3) Sometimes we see only what we want to see or don’t see what may be obvious to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory (矛盾的) information is particular??ly obvious, but it can be done. We can ignore (忽视) the stimulus He’s basically a good boy so what I saw was not shoplifting.
We can reduce the importance of the contradictory information — All kids (孩子) get into mischief (顽皮). Taking a book from the bookstore isn’t such a big deal. "We can change the meaning of the contradictory information." It wasn’t shoplifting because he was going to pay for it later. (from www.nmet113.com)
9. The first factor given by the author that affects our perception is ________.
A. the abilities of one’s auditory (听觉的) and visual (视觉的) sensors
B. cultural background and personal experiences
C. experiences one learns from others
D. critical measures taken by other people
10. While observing a particular person, ________.
A. one is likely to take all aspects (方面) to consideration
B. one pays more attention to his/her advantages
C. children often differ from grown-ups in perception
D. one tends to choose certain cues (提示) to look for
11. Observation of the same person by two people at the same time may differ because________.
A. their measuring yardsticks are not the same
B. either of them may be slow to catch information
C. the time for observation is not long enough
D. each of them uses different language to express his/her impressions
12. The word "stimulus" in paragraph 4 refers to________.
A. something attractive B. selective perception
C. contradictory information D. shoplifting
13. The worst thing in selective perception is that________.
A. perceived information runs against your desire
B. facts can be totally ignored or distorted (扭曲)
C. importance of the contradictory information can be overrated (估计过高)
D. the same information may not be dealt with in the same way
