4 . A five-year-old dog named Kelsey has been praised as a hero for helping to save the life of her owner who slipped in the snow and broke his neck.
The man, Bob, was alone when he left his Michigan farmhouse on New Year’s Eve to collect firewood. Expecting a journey of only several meters, Bob was wearing just long johns (秋裤), a shirt and slippers when he went outside, although the temperature was around－4 ℃.
After the accident, he was unable to move in the snow.Fortunately, Kelsey came to his assistance.
“I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10:30 pm,” Bob explained.“But my Kelsey came. By the next morning, my voice was gone and I couldn’t yell for help, but Kelsey didn’t stop barking.”
Bob’s companion kept him warm by laying on top of him.She licked his face and hands to keep him awake.“Kelsey kept barking but never left my side,” Bob recalled. “She kept me warm.I knew I couldn’t give up and that it was my choice to stay alive.”
Bob spent 19 hours in the freezing cold. When he finally lost consciousness, his dog kept barking.Finally, hearing the barking, Bob’s neighbor discovered him at 6:30 p. m.on New Year’s Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21 ℃. However, doctors were surprised to find that he didn’t have any frostbite (冻疮). They believed it was because of Kelsey’s determination to keep him warm. Dr. Chaim Colen, the doctor who treated Bob, said, “Animals can help and his dog really saved him ... he was very fortunate.”
Bob said he was “enormously” grateful for both Dr. Colen and his Kelsey. “They saved my life.They are truly heroes!”

Holidays with friends can be great fun and a good way of getting to know each other better.
Choose a place to visit. Going abroad will cost more but be a more exciting experience. Don’t go abroad if this is the first time you organize(组织)the holidays.
Collect your friends. Work out how many people you will be able to plan the trip for.
Meet up. Everyone will have their own idea of what the trip to be like, you should have a meeting.
Book transport(交通). When you decide on your hotel, you will know the dates of your stay and will be able to book transport, such as trains, buses and airplanes. Booking transport earlier can help you save some money.

With existing medical knowledge and skills, two thirds of the world’s 42 million blind should not have to suffer. Unfortunately, rich countries possess most of this knowledge, while developing countries do not.
ORBIS is an international nonprofit organization which operates the world’s only flying teaching eye hospital. ORBIS intends to help fight blindness worldwide. Inside a DC8 aircraft, there is a fullyequipped teaching hospital with television studio and classroom. Doctors are taught the latest techniques of bringing sight back to people there. Project ORBIS also aims at promoting peaceful cooperation (合作) among countries.
ORBIS tries to help developing countries by providing training during three-week medical programs. ORBIS has taught sightsaving techniques to over 35,000 doctors and nurses, who continue to cure tens of thousands of blind people every year. ORBIS has conducted 17 plane programs in China so far. For the seven to ten million blind in China ORBIS is planning to do more for them. At the moment an ORBIS is working on a longterm plan to develop a training center and to provide eye care service to Shanxi Province. ORBIS needs your help to continue their work and free people from blindness.
For just $ 38, you can help one person see; for $ 380 you can bring sight to 10 people; $ 1,300 helps teach a doctor new skills; and for $ 13,000 you can provide a training programme for a group of doctors who can make thousands of blind people see again. Your money can open their eyes to the world. Please help ORBIS improve the quality of life for so many people less fortunate than ourselves.

9 . It happens every spring. Flowers suddenly come out everywhere on the same day, as if they made an appointment with one another. But how exactly do plants “know” when to flower?
It is a question that has puzzled biologists for years. But according to Science Daily, a US research group may have finally answered it —the secret lies in a protein (蛋白质) called FKF1. This allows plants to sense the differences in day lengths so that they can tell the seasons are changing.
Researchers discovered the FKFI protein when they were studying a plant called Arabidopsis. They found that the FKFI protein is a photoreceptor (感光器). This means it is sensitive to, and can be activated by sunlight.
“Plants produce this protein every day in the late afternoon throughout the year. If there is no light at this time, for example, in winter when the sun goes down early, the protein won’t be activated,” explained Takato Imaizumi, the leader of the study. “But when spring comes and the days get longer, the FKF1 protein can be activated by daylight and the plants ‘know’ it is time to flower.”
Although researchers have only studied how the FKF1 protein works in the Arabidopsis, they believe that the process is similar in other plants, including crops like rice and wheat. This could be useful to the agricultural industry in the world.

10 . From a very early age, some children exhibit better selfcontrol than others. Now, a new study that began with about 1,000 children in New Zealand has tracked how a child’s low self-control can predict poor health, money troubles and even a criminal record in their adult years.
Researchers have been studying this group of children for decades now. They observed the level of self-control the youngsters displayed. Parents, teachers, even the kids themselves, scored the youngsters on measures like “acting before thinking” and “Persistence in reaching goals.” The study led by Moffitt of Duke University and colleagues followed 1,000 children from birth to age 32 in Dunedin, New Zealand.
“The children who had the lowest self-control when they were age three to ten, later on had the most health problems in their 30s,” Moffitt said, “and they had the worst financial situation. They were more likely to have a criminal record and to be raising a child as a single parent on a very low income.” Moffitt explained that self-control problems were widely observed, and weren’t just a feature of a small group of misbehaving kids.
Moffitt said it’s still unclear why some children have better self-control than others, though she said other researchers have found that it’s mostly a learned behavior, with relatively little genetic influence. But good self-control can be set to run in families because children with good self-control are more likely to grow up to be healthy and prosperous parents. But the good news, Moffitt said, is that self-control can be taught by parents, and through school curricula that have been shown to be effective.
