For photographers lacking training, experience and even the ability to click a shutter button, they produce remarkable pictures.Under the sea, deep in the woods and high in the sky, furry, feathery and leathery-skinned creatures are opening up vistas(远景)by taking cameras where no human can go.

This is the world of animal-borne imagine celebrated last month at a conference sponsored(supported) by the National Geographic Society for the 20th anniversary of its Crittercam, the device that started it all.

Since its debut(首次公开露面)in 1987 on the back of a turtle, the Crittercam and similar devices developed by others have grown smaller and more powerful.

“It’s more than just a camera now,” said Greg Marshall, the marine biologist and now filmmaker who invented the Crittercam.“We are now including more instruments to gather more data while at the same time reducing everything in size.”

The idea of attaching video cameras to animals came to Mr.Marshall in 1986 on a dive off Belize when a shark apporached him.When the animal quickly turned away, he noticed a shark with a sucker fish on its belly.He came up with the idea that putting a camera in place of the sucker fish would allow people to witness the shark’s behavior without disturbing it.

Crittercams have been attached to sharks, sea lions and other marine animals, and, more recently, to land animals.

Birds are a new addition, Mr.Marshall said.Dr.Christian Rutz of Oxford recently reported on tiny cameras called feathercams that monitor the crows in the South Pacific.It has discovered that crows are smarter than anyone knew they not only use twigs(嫩枝)and grass stems as tools to root out food, but they also save their favorite tools to use again.

Tracey L.Rogers, director of the Australian Marine Mammal Research Center in Sydney, said crittercam was a powerful tool in her work with leopard seals(豹斑海豹)in Antarctica.“In studying animals,” Dr.Rogers said at the meeting, “you want to see how our animal models align(与……一致)with reality.With a camera, you actually see what they do.You don’t have to guess.”

A group of students in Japan have created a realistic robot baby to motivate young people to start planning a family so as to increase the country’s birth rate. The automated (自动化的)doll developed at the University of Tsukuba, called Yotara, laughs and “wakes up” when a rattle is shaken.
He can become angry and sleep like a real baby and he smiles when his stomach is pressed. The robot can also sneeze and have a runny nose, thanks to a heated water pump system. The students of the Graduate school of Comprehensive Human Science at the university created the robot last year with touch sensors. A projector sends the facial features onto a warm silicon balloon which makes up Yotara’s face. The robot’s facial expression and body movements change according to pressure applied to different parts of its body.
The information collected through touch sensors(传感器)under the silicon skin is processed by a special programme. It then changes the baby’s expression projected onto the balloon-face from behind. There is a hat on the robot’s head and a colorful blanket covering the robot’s limbs which simulate wiggling(摆动) with the help of a geared motor. “We wanted to create a new type of robot that is soft, cuddly and cute,” said project leader Hiroki Kunimura.
“We’d like people to experience the innocent, joyful expressions typical of small babies. Through this experience, it would be great if some people started feeling that they wanted to have their own baby, if they started feeling that work is not everything.”
Japan’s birth rate is among the lowest in the developed world at 1.37%, compared to 2.12% in the United States and l.84%in Britain. Japan is facing serious economic consequences with over a quarter of its citizens expected to be aged over 65 by 20l5.The population is expected to reduce by a third within 50 years if the birth rate does not increase.
【小题1】. What is the students’ purpose of creating such a baby?

A.To help old people who live alone.B.To give small children some pleasure
C.To comfort lonely young people.D.To increase the population of Japan.
【小题2】What’s the new type of robot like in Hiroki Kunimura’s mind?
A.It can do everything for humans.B.It is clever, humorous and loyal.
C.It is gentle, lovely and smart.D.It makes humans unhappy.
【小题3】. What can we learn from the passage?
A.Many young people in Japan don’t want to get married.
B.There may be a lack of workers in Japan in the future.
C.The lifespan(寿命)of Japanese people will decrease in the future.
D.The birth rate in Japan will start to increase slowly soon.

WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand.

Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios.

The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day.

"The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore.

"Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday.

"It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle."

The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms.

1.What's the research really about?

A. Boys and girls.      B. Food and weight.           C. Sleep and health.          D. Screens and fat.

2.What's the result of less sleep for teenage boys?

A. Bigger waist and more fat in the body.

B. An increase in weight and height.

C. More concerned with their diet.

D. A decrease in bone and muscle.

3.From the sixth paragraph we can infer that ______.

A. girls usually sleep less and have healthier lifestyles than boys

B. the researchers expected to see the same result in girls

C. peoples' diet has a great effect on their health

D. boys are usually lazier than girls

4.Who would be the most pleased to hear the news?

A. Teachers.    B. Girls.         C. Parents. .            D. Boys.
