When Peary returned to the United States, he went to a businessman to sell some furs. There he met Matthew Henson, an African American mechanic, builder and navigator. When Peary went to Nicaragua on a Navy mission(任务),Henson went with him. When that job was over, the two headed to the Arctic.
Henson and Peary set sail for Greenland. When they landed, Henson built a house for their base camp. Peary and his men set out to explore the land by dog sledge(雪橇). Henson was injured and had to stay at the base. While there, he made friends with the Inuit, the native people.
In 1895 Henson, Peary and Hugh Lee went out on another dog sledge journey. This time, they found Greenland’s northernmost point. They now knew that the North Pole lay under the frozen Arctic Ocean. Peary had hoped to cross the ice. but the group ran out of food and returned to base camp. In the years that followed, Peary and Henson tried several times to reach the North Pole, but each time they failed. On one trip, Peary’s feet froze, and he lost his toes（脚趾）.
Peary and Henson planned last trip when Peary was 53 years old. They started across the sea ice from Ellesmere Island, which is located（位于） north of Canada. The temperature dropped as low as—51 degrees Celsius. The explores’ cheeks froze , and they suffered snow blindness from the sun’s glare. They experienced high winds and storms, and they also faced a hidden danger. Under the frozen ocean were powerful currents（潮流）. The ice moved and broke apart leaving open water, called leads. Twice Peary fell into leads. But eventually he and Henson became the first persons to reach the North Pole.

First-aid measures depend upon a victim’s needs and the provider’s level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal(脊柱)injury and paralysis(瘫痪).
Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious, should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking other people or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes(糖尿病)or heart trouble. The victim should be checked for a medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim.
First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim’s condition is known by the acronym(首字母缩写词)ABC, which stands for:
A---Airway: is it open and clear?
B---Breathing: is the person breathing? Look, listen, and feel for breathing.
C---Circulation: is there a pulse? Is the person bleeding extremely? Check skin color and temperature for additional indications of circulation problems.
小题1: First aid may bring about all the following results EXCEPT____.
| A．saving a victim’s life |
| B．preventing a victim’s condition from getting worse. |
| C．relieving a victim from pain |
| D．helping a person avoid sudden illness or injury |
| A．to make sure what to do and what not to do |
| B．to refer to all kinds of handbooks on first aid |
| C．to remove the ring or bracelet he/she may be wearing |
| D．to take him/her to a hospital at once |
| A．remove him from the accident scene | B．turn him over |
| C．call for professional medical help | D．examine him carefully |
| A．the importance of protecting the accident scene |
| B．some basic facts about first aid |
| C．what professional medical help is |
| D．who can offer first aid |
Noah"s Ark is aimed at collecting eggs, embryos(胚胎)，semen and DNA of endangered animals and storing them in liquid nitrogen（氮）. If certain species should become extinct , Dr. Duane Kraemar, a professor in Texas A&M University Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2,000 species of mammals , birds reptiles will become extinct in over 100 years . The panda, native only to China , is in danger of becoming extinct in the next 25 years .
This week , Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit . They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species t
o another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem，” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, ”adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first–ever attempt at cloning a dog.“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
小题1: The aim of “Noah’s Ark” project is to ________.
| A．make efforts to clone the endangered pandas |
| B．save endangered animals from dying out |
| C．collect DNA of endangered animals to study |
| D．transfer the nuclear of one animal to another |
| A．available panda eggs | B．host animals |
| C．qualified researchers | D．enough money |
| A．China’s Success in Panda Cloning |
| B．The First Cloned Panda in the World |
| C．Exploring the Possibility to Clone Pandas |
| D．China---the Native Place of Pandas Forever |
The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.

Honesty may well be the policy, but it often deserts us when no one is watching, psychologists report today. Experiments with an honesty box to collect payments for hot drinks show that people are better at paying up when under the gaze of a pair of eyes. The surprise was that the eyes were not real, but photographed.Researchers at Newcastle University set up the experiment in secret. They attached a poster to a cupboard of mugs above an honesty box alongside a kettle, with tea, coffee and milk. Over 10 weeks, they alternated (轮流替换) each week between images of eyes and pictures of flowers.
Dr. Bateson, a behavioral biologist and leader of the study, said that even though the eyes were not real they still seemed to make people behave more honestly. The effect may result from behavioral characteristics that developed as early humans formed social groups that increased their chances of survival. Individuals had to co-operate for the good of the group, rather than act selfishly.
“If nobody is watching us it is in our interests to behave selfishly. But when we think we’re being watched we should behave better, so people see us as co-operative and behave the same way towards us,” Dr. Bateson said.
“We thought we’d get a slight effect with eyes, by it was quite striking how much difference they made. Even at a subconscious level, it seems people respond to eyes, and that might be because eyes send a strong biological signal we have evolved(进化) to respond to.”
The finding, which researchers believe sheds light on our evolutionary past, could be turned to practical use. The psychologists say images of eyes could increase ticket sales on public transport and improve monitor systems to prevent antisocial behavior.
