A blind baby is doubly handicapped. Not only is it unable to see, 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).
The device is an improvement of the “Sonicguide”, an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart 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 closer an object is, 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 Denny’s 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 edges. Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her 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(聲納) device with somewhat the same sensitivity as Dennis’s for use by school-age children.
1.Dr. and Mrs. Daughters’ research is directed to ________.
A. 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 ________.
A. 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
3.What can we learn about infant Dennis’ device?
A. Its first design was designed for blind adults.
B. Its battery is as small as a half-dollar coin.
C. It is functionally similar to a sane and guide dog.
D. It has been improved by Telesensory Systems, Inc.
4.In the third paragraph, “its edges” refers to ___________ .
A. the edge of an object
B. the edge of the device
C. the boundary of Dennis’ movement
D. the boundary of the sound pitch.

I suddenly heard an elephant crying as though frightened. Looking down，I immediately recognized that something was wrong，and ran down to the edge of the near bank. There I saw Ma Sha with her three? month? old calf struggling in the fast rising water，and it was a life and death struggle. Her calf was floating and screaming with fear. Ma Sha was as near to the far bank as she could get，holding her whole body against the rushing water，and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean （完全地）over the mother's body and was gone. Ma Sha turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the rocky bank. Then with a huge effort，she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment，she fell back into the river. If she were carried down，it would be certain death. I knew，as well as she did，that there was one spot (地點) where she could get up the bank，but it was on the other side from where she had put her calf.
While I was wondering what I could do next，I heard the sound of a mother's love. Ma Sha had crossed the river and got up the bank and was making her way back as fast as she could，roaring (吼叫) all the time，but to her calf it was music.

Like lots of small-business owners, Lola Gonzalez had to decide to cut down her company’s nine-person staff (員工) when the economic recovery began to fail last spring. Unlike other companies, she picked an unlikely employee to lay off (解雇): herself.
Her business began to have problems in 2008 after going through her books (賬簿)
One day, her husband, Marcos, told her she had to reduce her payroll（薪金總額）by one person. Gonzalez said at a meeting, “I want you all to know that I have to lay somebody off and it’s been a very difficult decision. And that person is me.” Employees first froze in amazement and then burst into laughter until they realized she was serious. Gonzalez ’s employees said they were grateful for her kindness.
Her reason was simple. Although she ran the business and her employees did the legwork (跑腿), she thought she could find work more easily than her staff. Sure enough, she soon got a job as a social worker for a non-profit organization called Devereux Kids. She enjoys her social-worker job now, but the salary (薪水) cut has required some lifestyle changes. She and Marcos no longer eat out daily; they no longer pay for their son’s car and mobile phone, and they changed their car to a smaller one to save $300 a month.
Her business has picked up a bit recently and Marcos has begun to work part-time at Gonzalez’s company. Gonzalez says she has no plan to return to work at her company until the economic situation becomes better, perhaps in a year. Her employees, however, will get Christmas bonuses (獎金) this year.
1.How many workers are there in Gonzalez’s company at present?
A. 8. B. 9. C. 10. D. 11.
2.How did her employees feel at first when they heard Gonzalez’s decision?
A. Happy. B. Grateful.
C. Surprised. D. Unbelievable.
3. After leaving her company, _____________.
A. Gonzalez sold her car and went to work by bus
B. Gonzalez always had meals in a restaurant
C. Gonzalez’s son helped her a lot
D. Gonzalez changed her lifestyle a lot
4. From the text, we can learn that ___________.
A. Gonzalez will not return to her company in future
B. Gonzalez’s business has improved a little lately
C. Gonzalez got her social-worker job with great difficulty
D. Marcos lost his job and had to work at Gonzalez’s company
