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 to 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.”

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.
小题1:This passage is mainly about ____________.
A.the policy of honesty | B.an honesty box to collect money |
C.evolution on honesty | D.an experiment on honesty |
A.wanted to get a comparatively more exact result |
B.had known they wanted to do something illegally |

A.they want to leave a good impression |
B.they fear to be laughed at by others |

Our phones will be so smart in 10 years’ time that they’ll know everything about our situation and warn us when something needs our attention. This is the top prediction of both Nokia and Google. They predict that our cars and home appliances will be able to communicate with our mobile. For example, fridges will tell your mobile to tell you to pick up milk on the way back from work. While driving, your mobile will suggest that you take a different route because there’s a road accident up ahead.
The second trend is in gesture-based controls. People who know the iPhone’s touch-sensitive screen are already familiar with the technology. It translates hand movements into actions on-screen. But gestural communications will make the phone more convenient to use and may completely replace touchpads. According to industry insiders, the most immediate step forward in gestural technology will be in voice recognition. It’s believed voice recognition technology will speed up communications. It is quicker to speak than type. Eventually, phone screens will disappear.
The third major development will change our understanding of a mobile phone. From a single phone, the mobile will be developed into multi-part devices. It is opposite to the current trend in which mobile phones are combining the functions of cameras, music players and game consoles. The prediction is based on the idea that the world will become more wireless and all these—cameras, music players and game consoles—will be wirelessly connected. Mobile phones won’t need to contain these devices because users will be able to control them wirelessly through their phones.
小题1:The first paragraph serves as .
A.a lead-in | B.a conclusion | C.a summary | D.a supporting fact |
小题3:From the text, we can learn that the future mobile phones will .

B.be controlled by the users’ voices |
C.be controlled by home appliances |
D.be very big together with separated multiple parts |
A.three major trends of mobile phones |
B.what mobile phones will look like in 2020 |

Social Networking (人际关系网) Sites: Sites like MySpace and Facebook appeal to all generations and are a good way for a parent to understand what social standards your teen is living with. There are many ways to help you take part in your child"s online activities. You also can be from an onlooker (旁观者) who keeps a bird" s-eye view of his cyber world to an active member of his social group.
MMORPG: Massively Multiplayer Online Role-Playing Game comes in the form of games. A child can easily become addicted to (沉溺于) them if no limits are set. To fully understand the attraction behind MMORPG, you can make your own account and character to explore the digital (数码的) world. Playing the online games may seem strange at first to your teen, but experience has led me to only positive feedback (反应) from young people who can communicate with adults about their gaming experiences.
Text and Instant Messenger: The ways of teenage communication have produced a whole new language, such as "LOLZ" (laughing out loud) and "PSOS" (parent standing over shoulder). Learning the basic shorthand (速记法) of teens can open up a whole new world of communication, not only talking to your teens, but being able to listen on their terms as well. You may just find yourself texting faster and ending your correspondence (联系) with TTYL (talk to you later). To teens, texting anyone looks cool, even Mom and Dad.
Email: Emailing your child is easy. This, of course, cannot take the place of face-to-face communication, but it provides another way for your child to reach you. Another benefit is that your child cannot act like he didn"t hear you.
