    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.

How to Make Friends

    Friendship is a very important human relationship and everyone needs good friends. Good friendship has many benefits. It offers companionship, improves self-worth and promotes (促进) good health. There are times in our lives such as when we have recently moved into a new town, or changed our jobs or schools.

    Friendship Day is celebrated every year on the first Sunday in the month of August. People give their loved ones or friends friendship bracelets (手镯) and other gifts to celebrate their friendship. The culture of friendship bracelets is as old as even thousands of years.

    After the World WarⅡ, the paracord(伞绳) bracelets became very popular. These were also known as survival bracelets. One of the main reasons is that it was often used for a rescue purpose. Paracord, used in the parachute(降落伞), does not wear away(磨损) easily and is strong and durable. Because of its light weight, people could carry it along easily. If required, it could be made a very long rope and be used as a rescue rope. Hunters used it to find their way that they could return without getting lost.

    Today there are all kinds of paracord bracelets, made of coloured strings. Girls like thinner and colourful bracelets. Many choose to make the bracelets by themselves for their dear friends. This not only appeals more to the feelings of people but also makes them know how much their friends mean to them. People keep the bracelets given by their friends long. Many people choose coloured strings keeping the depth of their friendship in mind. White, yellow, orange and red show the different levels of friendship. Pure friendship is shown in white; the red colour means love. An orange friendship bracelet is given to show strong friendship and yellow as simple friendship. Today, not only do the young people sport(显示) these friendship bracelets, but even the old do.

    Does friendship have an age? Yes. Friendship is like the wine, and the older you get, the older and stronger your friendship is.

    In China, Double Eleven Shopping Day is approaching. And there is a similar case in the United States—Black Friday. It has been regarded as the beginning of the holiday shopping season. Although it's not an official holiday, millions of employers give their employees the day off, and many people use that day to get a jump-start on their holiday shopping. A similar day in Canada and Great Britain is called "Boxing Day".

    Black Friday has become somewhat of a marketing sensation in recent years. Since 2005, it has been the busiest shopping day of the year. To lure shoppers, retailers (零售商) routinely open their doors as early as 4 a.m. and offer special sales and promotions to the shoppers that arrive early. Some of the special deals offered by stores are only available in limited quantities. That is why some shoppers intent on getting the best deals often camp out in front of stores overnight so that they'll be the first in line when the doors open.

    But why is it called Black Friday? Historians believe the name started in Philadelphia in the mid-1960s. Bus drivers and police used "Black Friday" to describe the heavy traffic that would block city streets the day after Thanksgiving as shoppers headed to the stores.

    Businesses, however, didn't like the negative tone associated with the "Black Friday" name. In the early 1980s, a more positive explanation of the name began to circulate. According to this alternative explanation, Black Friday is the day when retailers finally begin to turn a profit for the year. In accounting terms (会计行业), operating at a loss is called being "in the red" because accountants traditionally used red ink to show negative amounts. Positive amounts were usually shown in black ink. Thus, being "in the black" is a good thing because it means stores are operating at a profit.

    Recently, for those who are too busy to shop on Black Friday or who just don't want to fight the crowds, the Monday following Black Friday has become known as Cyber Monday (网络星期一) for the many online deals.

    Metal-organic frameworks(MOFs) are compounds that are set to solve some tough challenges: producing water in the desert, removing greenhouse gases from the air and storing dangerous gases more safely.

    The Arizona desert is really dry. Anyone stuck in it without water would die from dehydration (脱水) within three days. Unless, that is, they had one of Omar Yaghi's next-generation water harvesters. Although daytime humidity(湿度)is only about 10 per cent, this rises to 40 per cent at night, which means there's enough water in the atmosphere to support life — if it can be transformed into liquid form.

    That's exactly what Yaghi's device does. It's a box about the size of a small microwave oven designed to suck the humidity from the air at night and turn it into drinking water the next day using only the heat of the sun as its power source. What makes it work is a special material called a metal-organic framework (MOF), which at normal temperatures attracts water molecules (分子) onto its surface of its internal pores(细孔). Warm it up and the water is released, each harvest producing one-third of a cup of pure drinking water.

    "With further improvements, a device, the size of a washing machine, could produce enough water for the basic needs of a household," says Yaghi, a chemist at the University of California. One-third of the world's population lacks safe drinking water; for them such a device could be a lifesaver.

    These crystalline cluster(结晶群)of metals, such as aluminum or magnesium, linked by organic molecules can be made into materials with an extremely high absorption ability, attracting specific molecules to their surface. In this way, MOFs cling to a variety of liquids and gases.

MOFs work thanks to their unique structure—large quantities of nanometer-sized internal spaces. In fact one MOF has so many pores that they would cover an area as large as six football fields. MOFs are also extremely stable light and have many different uses: their molecular structure can be varied to attract specific molecules, such as water, and their pores can be designed to best store them. Adding a small amount of heat or pressure causes the MOF to release what it is holding. More than 70,000 different MOFs have been produced to date for various applications.

    The San Francisco Giants added a special pitcher(投球手)for the day. It was small—yet fierce—Hailey Dawson, who has a 3D-printed hand.

    The energetic 8-year-old from Nevada was invited to throw out the first pitch at the Giants game on Sunday. Dawson was born with Poland syndrome(综合症), a disorder in which affected individuals are born with missing or underdeveloped muscles on one side of the body. It affected her hand.

    With a traditional prosthetic(假肢)potentially costing thousands of dollars, Hailey's mom, Yong Dawson turned to the University of Nevada, Las Vegas for help. She emailed UNLV engineering, and they accepted the challenge. Brendan O'Toole, chairman of the mechanical engineering department, said he and his team had got a lot of requests, "but this one was different." They got to work using a 3D-printer.Several prototypes(原型)and fittings later, Dawson got her first hand about four years ago.

    Hailey's mother said the hand had given her daughter a wonderful lift. "When she puts this robotic hand on, it changes her personality and confidence level," Yong Dawson told CBS San Francisco. "I love seeing that. I just wanted her to have an even playing field."

    When she arrived at AT&T Park on Sunday, Hailey got to hang out with players in the shelter at the side of the sports field. They even let her try on their World Series rings.

    Using her 3D-printed hand, Dawson threw out the perfect first pitch. Then with a wave and a smile, she headed into the stands to cheer on her newfound friends on the Giants.
