Our skins let us know whether the air is moist or dry, whether surfaces are wet without being sticky or slippery. From the uniformity of slight pressure, we can be aware how deeply a finger is thrust into water at body temperature, even if the Anger is enclosed in a rubber glove that keeps the skin completely dry. Many other animals, with highly sensitive skins, appear to be able to learn still more about their environment. Often they do so without employing any of the five senses.
By observing the capabilities of other members of the animal kingdom, we come to realize that a human being has far more possibilities than are utilized. We neglect ever so many of our senses in concentrating on the five major ones. At the same time, a comparison between animals and man draws attention to the limitation of each sense. The part of the spectrum (光谱) seen by colour-conscious man as red is non-existent for honey-bees. But a bee can see far more in flowers than we, because the ultra-violet (紫外线) to which our eyes are blind is a stimulating (刺激的) part of the insect's spectrum, and, for honey-bees at least, constitutes a separate colour.
From the passage we realize that ______.
A.man possesses far more senses than the five major ones
B.man possesses a few more senses than animals
C.man possesses as many senses as animals
D.man has fully utilized his senses

Many people believe the glare(耀眼的强光)from snow causes snowblindness. Yet, 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 the glare from snow does not cause snowblindness in troops in a snow-covered country. Rather, a mans eyes frequently find nothing to focus on in a broad expanse of a snow-covered area. So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscle aches. Nature balances this annoyance by producing more and more liquid which covers the eyeballs. The liquid covers the eyeballs in increasing quantity until vision blurs(模糊). And the result is total, even though temporary, snowblindness. Experiments led the Army to a simple method of overcoming this problem. Scouts(侦察兵)ahead of a main body of 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 too can focus. 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 through the snow-blanketed landscape. By focusing their attention on one object at a time, the man can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white area is overcome. Question: The first paragraph is mainly concerned with______.
A.snow glare and snowblindness
B.the whiteness from snow
C.headaches, watering eyes and snowblindness
D.the need for dark glasses
Dear editor,
Why do newspapers have so many advertisements for electronic (电子的) equipment? Last Sunday I counted ads. For seven kinds of televisions and thirteen kinds of radios in the Youth Journal. Besides that, there were pages and pages of ads for Citizens Band radios and tape recorders.
Don't you realize what electronic equipment is doing to our daily life? Everywhere you go you may hear loud music and advertisements over radios; this continuous noise is doing harm to our ears. Husbands don't talk to wives any more; they are always watching the news or a ball game. Children's eyes become hurt with endless hours of watching not only the programs for children but also those for grown-ups as well. And worse, hidden microphones find out our personal lives, and computers keep records of personal information about us.
That is enough! I think you should limit the amount of advertisement of electronic equipment in the Youth Journal, or it will make life unbearable (难以忍受的) for us all.

PROTECTING EYES FROM COMPUTER SCREENS
Many of us spend the bulk of the day looking at computer screens. Reading this article means there’s a good chance you’re looking at one right now.
But does looking at computer screens damage your eyes? Professor Nathan Efron does not consider computer screens “harmful” to our eyes.
But he admits if you use one a lot, you increase your risk of becoming slightly more short-sighted –where your eyes focus well only on close objects while more distant objects appear blurred. This is especially the case for children and young adults, whose eyes are still developing.
In the shorter term, prolonged viewing of a computer screen can make any slight existing vision defects more noticeable. It can also give you what is sometimes known as “computer vision syndrome” – eye strain, headaches, gritty eyes and blurry vision. But this is only temporary and can be minimized by:
Adjusting the screen display so the contrast is high and the brightness feels comfortable.
Having lighting that does not produce glare on the screen.
Giving your eyes regular rests from looking at the screen (The Optometrists Association of Australia recommends you do this for five to ten minutes every one to two hours of computer use. It's a good time to make phone calls or do other tasks.)
1. Many of us spend much time looking at computer screens. {T; F}
2. Looking at computer screens for long time doesn’t damage children and young adults’ eyesight. {T; F}
3. Computer vision syndrome cannot be weakened. {T; F}
4. It’s good taking breaks during screen watching. {T; F}
5. Proper lighting is important to protect our eyes. {T; F}
