　　[科普知識(shí)型閱讀理解(一)]but because it cannot receive the visual stimulus(刺激)from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the ten-month-old son of Dr and Mrs Dennis Daughters is the subject of an unusual psychological experiment designed to prevent a lag(滯后)in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant(嬰兒) Dennis is learning to identify the people and objects in the world around him by means of echoes(回聲)．， an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a sane or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic(超聲的) pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch(音調(diào)) and volume(音量) with the size and distance of the object.the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Dennis' sends back a louder sound to his right ear than to the left. Thus, by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound(超聲波) passes its_edge. Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on his knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. “From the first time he wore it，” says Mrs Daughters, “it was like a light going on in his head.”

　　What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further into his environment.

　　Meanwhile, Telesensory, Inc., is working on the development of sonar(聲吶) device with somewhat the same sensitivity as Dennis' for use by school-age children.________．helping the blind to see and learn as well as others

　　B．benefiting the learning process of blind children

　　C．solving blind children's psychological problems

　　D．finding out how children develop intellectually

　　2. Infant Dennis becomes the subject of the experiment most probably because ________．he already lags behind the sighted children

　　B．he leads a life as normal as any other children

　　C．he is at the early stage of the learning process

　　D．he has the aid of a sonar-type electronic device

Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing, our family and friends may accept us, but the workplace may not.

　　A high school newspaper editor said it is unfair for companies to discourage visible tattoos (紋身) , nose rings, or certain dress styles. It is true you can’t judge a book by its cover, yet people do “cover” themselves in order to convey (傳遞) certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances, so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept.

　　Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees (雇員) , because those people represent the companies to their customers.

　　As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well- qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open- minded, I can’t expect all our customers are.

　　There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.

　　1. Which of the following is the newspaper editor’s opinion according to Paragraph 2?

　　A. People’s appearances carry messages about themselves.

　　B. Customers’choices influence dress standards in companies.

　　C. Candidates with tattoos or nose rings should be fairly treated.

　　D. Strange dress styles should not be encouraged in the workplace.

　　2. What can be inferred from the text?

　　A. Candidates have to wear what companies prefer for an interview.

　　B. What to wear is not a matter of personal choice for companies.

　　C. Companies sometimes have to change to respect their candidates.

　　D. Hiring managers make the best impression on their candidates.

　　3. Which of the following would be the best title for the text?

　　A. Employees Matter

　　B. Personal Choices Matter

　　C. Appearances Matter　

　　D. Hiring Managers Matter

　　4. The author’s attitude towards strange dress styles in the workplace may best be described as　.
