The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii.

The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos（胚胎）. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said.　　 “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that

can be cheaply extracted, especially in countries that can’t afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

The rabbits are expected to have the same life span as their non-glowing counterparts（副本）, but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

"To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

1.Moisyadi’s attitude towards this kind of experiment is　　　　　　 .

A. doubtful.

B. indifferent.

C. supportive.

D. objective.

2.How did glowing effect produce?

A. It was just the result of genetic selection.

B. Put a light into a mother rabbit’s embryos.

C. Injected glowing cats DNA into a mother rabbit’s embryos.

D. Injected Jellyfish DNA into a mother rabbit’s embryos.

3.The final goal of this research is　　　　　　 .

A. To make animals cuter.

B. To make nights brighter.

C. To produce all kinds of glowing animals.

D. To produce beneficial molecules in animals’ milk.

4.What can we learn according to the passage?

A. The life span of glowing rabbits is much shorter than that of non-glowing ones.

B. The glowing rabbits were born only at the University pf Hawaii.

C. Scientists have created glowing cockroaches and cats before.

D. Three rabbits out of eight can glow in the experiment.

Dogs can tell how other dogs are feeling from the way their tails are wagging (摇摆), according to researchers who monitored the animals’ heart rate as they watched dogs’ movies. The Italian team found that dogs had higher heart rates and became more anxious when they saw others wag their tails more to the left, but not when they wagged more to the right, or failed to wag at all.

The curious form of communication is probably not intentional, or consciously understood, but is instead an automatic behavior that arises from the structure of the brain, said Giorgio. “It’s not something they clearly and exactly understand,” Giorgio told The Guardian. “It’s just something that happens to them.”

Giorgio traces the effect back to the way the two halves of the brain process different experiences. In a previous study, his team showed that when a dog had a positive experience, activity rose in the left side of the brain, bringing about more tail wagging to the right. Or else more tail wagging to the left. The effect is barely visible to the human eye because dogs tend to wag their tails too fast, but it can be seen with slow motion video, or in some larger types.

In the latest study, the researchers wanted to find out whether the direction of tail wagging had any effect on other dogs. To get an answer, they fitted dogs with vests that recorded their heart rates, and played them movies of other dogs wagging their tails one way and then the other. To ensure the dogs reacted only to tail wagging, and not appearance, they repeated the experiment with dogs that appeared only as shadows.

“When dogs saw other dogs wagging their tails to the right, there was quite a relaxed reaction and no evidence of an increased heart rate. But when the wagging was to the left we saw an increase in heart rate and a series of behaviors typically associated with stress, anxiety and being more watchful,” Giorgio said. The anxious animals held their ears up, breathed, and kept their eyes wide open. The study appears in the latest issue of Current Biology.

1.What does the text focus on?

A.Animal protection. B.Animal psychology.

C.Animal tests. D.Animal welfare.

2.What leads to dogs’ wagging tail to the left or right according to Giorgio?

A.Their automatic behavior. B.Their conscious response.

C.Their increasing heart rate. D.Their selective preference.

3.At what time do dogs have more tail wagging to the right?

A.When they run quickly. B.When they feel hungry.

C.When they feel stressed. D.When they play with their owners.

4.What can we learn from the text?

A.Giorgio did the research on his own.

B.The effect of dog’s wagging tails can be seen by human eyes.

C.A dog keeping his eyes wide open may show he is nervous or worried.

D.The findings of the study will help with wildlife protection.

Research shows that playful teasing between parents and their children can be a way to strengthen relationships, bring up difficult topics, and just have fun. 1. Carol Bishop says, “You need to recognize if they are enjoying it,” There are also rules about what is okay and not okay to tease your child about. 2. Instead, tease kids about safe topics, like a messy room, or things that can be easily changed.

Teasing should also be a two-way street. 3. If they go too far making fun of you, be sure not to blow up. Instead, help them to learn boundaries and what may hurt others.

Teasing about a disappointing grade should only be used as a gentle reminder to study or do homework. It shouldn't be focused on the ability because that could make the situation worse. It’s not wrong to say to your child, “I'm disappointed that you got a C.”4. You need to examine if there is a learning disability or maybe they are depressed or being bullied.

From monsters under the bed to darkness and noises, fears that may seem silly to an adult may be very real to a child. 5. In fact, it could make them worse. Teasing a child who is frightened about something is not a way for them to expand their horizon—you need to make them feel secure.

A.Kids often feel hurt when teased by others.

B.Topics like appearance and weight are prohibited.

C.You have to be willing to let your child tease you about things.

D.But then you must work with them to figure out the cause.

E.But parents need to recognize when teasing becomes hurtful.

F.Laughing or teasing won't help them overcome their fears.

G.Teasing a child about sports performance can cause a child to quit the sport.

An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (迁徙).

Migratory birds ( 候 鸟 ) flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. “In English-language Wikipedia ( 维基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States,” said the lead author John Mittermeier.

And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.

This finding suggests new ways to monitor changes in the world’s biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.

Mittermeier is encouraged by the search results. He commented, “I think there’s a concern among conservationists (生态环境保护者) that people are losing touch with the natural world and that they’re not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people’s Wikipedia interest closely related to changes in nature.” Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, “By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help.”

1.What have researchers found about species searches?

A.They strengthen ties among people. B.They affect the animal movements.

C.They reflect animal migration seasons. D.They differ in language backgrounds.

2.What is the purpose of writing Paragraph 3?

A.To further support the research findings.

B.To show the variety of species searches.

C.To summarize the research process.

D.To present researchers’ heavy work load.

3.How does Mittermeier feel about the search results?

A.Sad about people’s not getting close to nature.

B.Worried about Wikipedia behavior.

C.Amazed at people’s care about nature.

D.Satisfied with Wikipedia’s service.

4.From which is the text probably taken?

A.A scientific magazine. B.A biology textbook.

C.A biography. D.A travel brochure .
