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（滞后）in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant(婴儿) Dennis is learning to identify the people and objects in the world around him by means of echoes(回声).

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(超声的) 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(音调) 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(超声波) 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(声纳) 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.

It is sometimes thought that the longing for material goods, the need to buy things, is a relatively modern invention. 1. Trade or shopping is certainly an ancient desire, and existed before our ancestors invented writing, laws, cities or farming, even before they used metal to make tools.

Humans are born to trade. 2. Evidence from hunter-gatherers suggests that the exchange of food and other necessary things comes naturally, as well as the ability to keep a record of the credits involved. And once trade begins, the benefits are hard to resist.

Ancient local coastal people in northern Australia traded fish hooks, along a chain of trading partners, with people living 400 miles inland, who cut and polished local stone to make axes (斧子). 3. Finally, both groups of “producers”, by concentrating on things they could produce and exchanging them for other things they needed, benefited as a result.

Trade in the necessities of life, such as food and simple tools, is not really surprising, considering the link between these basic items and survival. What is surprising, though, is that our taste for unnecessary expensive objects also goes back a long way.

In South Africa, 100,000-year-old decorative dyes (染料) have been found in an area where none were produced. 4. Small round pieces of glass 76,000 years old were also found at the same place. The earliest jewellery known to us were not just random findings — they were grouped together in size and had holes like those used for threading onto a necklace.

Archaeologists argue that trade prepared the way for the complex societies in which we live today. 5. However, their modern equivalents — fast cars and expensive clothes — hold the same attraction for us as “trade goods” did for people 100,000 years ago.

A.And we don’t need shops or money to do it.

B.These are powerful evidence for cash purchase.

C.In fact, its roots go back to the beginning of humanity.

D.However, first trade began from the exchange of objects.

E.Modern-day shoppers may not be impressed by ancient glass pieces.

F.It is thought that these goods were bought at least 30　 kilometres　 away.

G.Every individual along the chain made a profit, even if he produced neither himself.

阅读下面短文，简要回答问题。

One of the greatest things about growing older is that you get to stay up late. It’s not just your parents who that decision. Your body lets you enjoy dark hours, too.

Resent study has shown that brain changes during teen years make it easier for kids to stay up late. “But it doesn’t mean that you should stay up late just because you can stay up late,” scientists say. Young people who don’t get enough sleep are often late for school, or they miss it completely. And their grades go down. “If you’re sleeping in school, you’re not learning,” says Mary Carskadon who is a sleep researcher.

Lack of sleep is a growing problem in the United States. Schools have been starting earlier in recent years. And with TV, computers, and video games attracting them, people of all ages are sleeping less than their parents or their grandparents did.

Sleep is important because it gives our bodies time to recover from the stress (压力) of living. Studies show that the adults (成人) who sleep less than 6 hours a night have mote heart problems and die sooner than the adults who sleep 7 to 8 hours a night.

How much sleep do you need? It depends mainly on your age. Babies often sleep for the most of the day. By the time they’re 10 years old, kids need an average of 10 hours a night. As they get older, kids have signs to sleep less. But given the chance in an experiment to sleep as long as they want to, young teenagers have 10 hours of sleep. There are even some indications that teenagers may need more sleep than younger kids.

1. Find in the passage a word closest in meaning to the underlined word “indications”.（在文章中找一个与indications意义相近的词） (2分)
