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.

Most children now chat daily either online or through their mobile phones. They are connecting to a huge number of other children all over the world. Some are shy “in real life” but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can introduce problems, such as arguments. Going online is great fun, but there are also a few people who use the Internet for offensive (冒犯性的) or illegal aims. Children must be made aware of both the good things and the dangers.

To keep children safe your management must cover the family computer. Just as you decide which TV programs are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (警惕).

Computer studies are part of schoolwork now, so it’s likely that your children may know more than you do. We get left behind when it comes to the latest gad-gets and the interactive areas of websites, like chat rooms and message boards, which are especially strange. The language of chat is strange to many parents, too. Chatters love to use abbreviations (缩写) such as: atb — all the best, bbfn — bye bye for now, cul8er — see you later, gr8 — great, Idk — I don’t know, imbl — it must be love, kit — keep in touch, paw — parents are watching, lol — laugh out loud, xlnt — excellent!

1.The passage is meant for ______.

A. children B. parents

C. teachers D. net bar owners

2.Which of the following will the author probably agree with?

A. The Internet is no good for children.

B. The chat language is strange to adults.

In this day and age,it may seem that getting two people with different views together to discuss them leads to a disaster.Just think about what would happen if you sat down and had an open and honest conversation with someone with completely opposing views.Could it bring you closer together?

However,the Human Library Organization is counting on it.At a Human Library,people volunteer to become "books" and make their experiences open and available."Readers" are encouraged to ask them questions freely,and they'll get honest answers in return.There's no judgment,and no questions are off—limits.

You won't find unpleasant comments,and you won't lose faith in humanity.At the Human Library,you actually feel letter about the world you live in.You might even make a new friend!

"The human books consist of people who have been discriminated by society."said Ronni Abergel,the Human Library Organization's founder,who has set out to build a space for conversations that can challenge prejudices through dialogue."The most pleasantly surprising thing about it is how close all the human books become to one another."she said.

Human Libraries help to remind us there really is more that unites us than divides us.And as events now spread throughout 82 countries,with Human Libraries even set to launch soon in Pakistan and Jordan,you can tell that is a shared feeling.

"We can spend billions and billions in trying to build up homeland security and our safety,but real safety comes from having positive relations to other groups in your community."said Abergel,"Real safety is not going to come from building walls.It's going to come from reaching out and getting to know each other."

One October morning, I got off the all-night train in Mandalay, a city in Myanmar. A rough man came up and offered to show me around. The price he asked was less than I would pay for a bar of chocolate at home. So I climbed into his trishaw(三轮车).

As he was showing me around, he told me how he had come to the city from his village. He’d earned a degree in mathematics. His dream was to be a teacher. But of course, life is hard here, and so for now, this was the only way he could make a living. Many nights, he told me, he actually slept in his trishaw so he could catch the first visitors off the all-night train.

And very soon, we found that in certain ways, we had so much in common---we were both in our 20s, we were both fascinated by foreign cultures----that he invited me home.

So we turned off the wide, crowded streets, and came to rough, wild alleyways(小巷). I really lost my sense of where I was, and realized that I could easily get cheated or something even worse.

Finally, he stopped and led me into a hut. And then he reached under his bed. Something in me froze. I waited to see what he would pull out. And finally he took out a box. Inside it was every single letter he had ever received from visitors from abroad.

So when we said goodbye that night, I realized he had also shown me the secret point of travel, which is to go inwardly(向内心)as well as outwardly to places you would never go otherwise, to go into uncertainty, even fear.

At home, its dangerously easy to think we’re on top of things. Out in the world, you are reminded every moment that you’re not, and you can’t get to the bottom of things, either.

How can I carry out a group project?

Group projects can be so overwhelming (使人不知所措的), especially when people don’t cooperate and follow through. “1.” To follow this wise advice from expert Julie Hochheiser IIkovich, simply break down that hug project into smaller jobs that can be tracked. Here’s exactly how to do it:

●List it. The day the project is assigned, immediately identify the end goal. 2.This should include everything from minor tasks to major ones.

●Schedule it.3.This should include meetings, tasks, and deadlines. Assign each person a color and highlight each task with those colors, so it’s clear who is doing what.

●Track it. As a team, decide on a project manager who will keep everyone on track, and who you agree is allowed to call team members out if they’re not hardworking. (Advice on how to choose: 4.)

As stressful as group work is, it can actually be beneficial in the long run. At first, groups that work well together can achieve much more than individuals working on their own. And being part of a team will help you develop your interpersonal skills. Also, working with others will help identify your own strengths and weaknesses. 5.

A. Give feedback on group processes to groups

B. Then list what needs to get done to accomplish it

C. Look for the person with the most organized desk!

D. A half-hour of planning saves a week of stress at the end!

E. Create a timetable for the project and put everything from the list on it.

F. This sense about yourself will be invaluable when you enter the workforce.

G. Group projects can help people develop new approaches to solving problems.

“Don’t get discouraged, Hallie,” Kathy said, comforting her with a hug. “It sounds as if you have a bit of a mystery to solve. Maybe you should do a little spying on Maya.”

Feeling better, Hallie put on her scuba gear(潜水服)again and waited. Maya, the dolphin, had been swimming playfully, but suddenly she threw herself to the back of the tank where the filter box(过滤箱)was located. She stuck her nose down behind the box and then swam away.

Hallie followed Maya. “What was she doing here?” she wondered. When she looked behind the box, her question was answered. She swam back and saw Maya was in front of Kathy with a comb in her mouth waiting for her treat.

“Maya! Where did you get that?” demanded Kathy, taking the comb and throwing her a fish.

“I know,” declared Hallie, handing Kathy a handful of items, “I followed her to the filter box and these are what I found.”

From the look on Kathy’s face, Hallie knew everything was beginning to come to light.

“Do you remember the other day you said that Maya really liked her treats?” asked Kathy.“Well, I think this was more than a training exercise for Maya. Every time you found something in the tank, that meant one less fish for Maya. She couldn’t bring all the items to me at once, so she found a hiding place for them. That way you came up empty-handed, but Maya would always get her treat.”

“Okay, Maya,” said Hallie facing the dolphin, “you win! The treats are all yours.”

Maya dived down, and then jumped out of the water, turning herself over in midair. Shaking their heads in disbelief, Hallie and Kathy reached for the fish. Maya deserved the treat.

1.What was the “mystery” in the story?

A. The secret of Maya’s finding the items.

B. The secret of Hallie’s winning the game.

C. The reason for Maya’s liking her treats.

D. The reason for Hallie’s spying on Maya.

2.Maya hid the items because she considered Hallie as a ________.

A. spy

B. competitor

C. playmate

D. trainer

3.At the end of the story, Hallie and Kathy thought Maya was ________.

A. energetic

B. genuine

C. loyal

D. smart
