1 . Food experts say washing could spread the germs on your turkey in the kitchen sink or nearby food. But it's been a challenge trying to convince cooks to stop rinsing （冲洗）off raw poultry. Germs that can make people sick are common in the guts of healthy poultry and are legally allowed to be on raw turkey and chicken. The assumption is that nobody eats their poultry raw, and that thorough cooking will kill the bacteria.
The do — not — wash raw poultry advice from the USDA is relatively new and perhaps hasn't caught on because it goes against the common belief that washing makes things clean, said Chapman. Benjamin Chapman, a study author and food safety expert at North Carolina State University, said the instinct to wash raw poultry goes back at least decades when people relied more on visual clues to spot problems with poultry. Meanwhile, washing hands and surfaces are also important.
But food preparation is a complicated act, and germs from poultry can be spread even if it's not washed, especially when birds are removed from packaging.
The USDA-funded study stresses that point. Researchers sprayed raw chicken with a harmless strain of E. coli （大肠杆菌）and watched volunteer cooks at test kitchens. Among those who washed their raw chicken, about a quarter ended up spreading the bacteria to their lettuce. But even some of those who did not rinse the chicken got germs on the lettuce. And there are other opportunities for germs to survive on turkeys: melting and cooking.
To ensure a bird is thoroughly cooked, they say to use a thermometer to check that the deepest and thickest parts of it have reached 165 degrees. Even after the meal is cooked, you aren't out of the danger zone. To keep turkeys and other leftovers safe, experts say they should be refrigerated after two hours.

2 . Learning a second language is difficult at any age and it only gets harder the longer you wait to open that dusty French book. Now, in a new study, scientists have pointed the exact age at which your chances of reaching fluency（流利）in a second language seem to rise： 10.
The study, published in the journal Cognition, found that it's "nearly impossible” for language learners to reach native-level fluency if they start learning a second language after 10. But that doesn't seem to be because language skills go downhill “It turns out you're still learning fast. It's just that you run out of time, because your ability to learn starts dropping at around 17 or 18 years old,“ says study co-author Joshua Hartshorne, an assistant professor of psychology at Boston College.
Kids may be better than adults at learning new languages for many reasons. Children's brains are more plastic than those of adults, meaning they're better able to adapt and respond to new information. "All learning involves the brain changing,“ Hartshorne says, “and children's brains seem to be a lot more skilled at changing. "
These findings may seem discouraging, but it was heartening for scientists to learn that the critical （关键的）period for fluent language acquisition might be longer than they previously thought. Some scientists believed that the brief window closes shortly after birth, while others stretched it only to early adolescence. Compared to those estimates, 17 or 18 when language learning ability starts to drop off——seems old.
“People progress better when they learn by immersion （沉 浸）rather than simply in a classroom. And moving to a place where your desired language is spoken is the best way to learn as an adult. If that's not an option, you can create an immersive environment by finding ways to have conversations with native speakers in their own communities," Hartshorne says. By doing so, it's possible to become conversationally fluent——even without the advantage of a child's brain.

3 . If Confucius(孔子)were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.
While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.
But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.
In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and
philosophy(哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks(缺陷)of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.
So the old thinker's ideas are still alive and well.
Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.
As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

5 . While some customs like setting off fireworks and counting down the last few seconds seem universal, many countries have their own unique New Year’s Eve traditions.
Denmark: Break plates
A Danish tradition is to throw plates and dishes against friend’s and neighbor’s front doors. It’s a bit of a popularity contest as the bigger the pile of broken china is the next morning, the more friends and good luck you’ll have in the coming year.
Germany: Pouring lead
In Germany, people melt small pieces of lead in a spoon over a candle, then pour the liquid into cold water. The shapes from the lead pouring are supposed to reveal what the year ahead will bring. If the lead forms a ball, luck will roll one’s way, while the shape of a crown means wealth; a cross means death and a star will bring happiness.
Spain: Twelve grapes of luck
In Spain, one New Year’s tradition is to eat 12 grapes, one for each month of the coming year, to secure prosperity (繁荣). You need to eat one grape with each bell strike at midnight. The tradition dates from 1909 when farmers in Alicante came up with this idea to sell more grapes after an exceptional harvest.
Philippines: Round food, round clothes, round everything
In the Philippines, the start of the new year is all about the money. The locals believe that surrounding themselves with round things (to represent coins) will bring money or fortune. As a result, clothes with dots are worn and round food is eaten.

6 . Passenger pigeons were the most common birds in all of North America in the 1800s. It was common to see large groups of passenger pigeons — group that made a sound like a storm.
But today, they are extinct because of human behavior. Now, some scientists want to bring passenger pigeons back to life by using new technology and scientific ideas. They call this process de-extinction
De-extinction has not happened yet. It is still just an idea. The process of de-extinction is not easy. First, scientists must collect DNA from the bodies of extinct animals. Then they will put it in the eggs of similar animals species. When these animals become adults, they will have babies. And these baby animals will have the DNA of the extinct animals.
Scientists believe it is possible to bring back passenger pigeons and many other animals. However, not everyone think this is a good idea.
Stewart Primm is the world’s leading expert on modern animal extinction. He believes that bringing extinct animals back to life is bad for the earth. On the one hand, these animals no longer have a safe place to live. On the other hand, they could cause other animals to die.
Many other scientists do not agree with Stewart Primm. Stuart Brand, a writer and scientist, is one of them. He believes de-extinction is good for many reasons.
“The current generation of children will experience the return of some unusual animals in their lifetime. It may be part of what defines their generation and their attitude to the natural world. They will take their parents to zoos to see the growing populations of passenger pigeons, and maybe even dodo birds. This will provide a good deal of money for zoos busy with extinct species restoration (恢复). Humans killed off a lot of species over the last 10,000 years. So, it’s right to bring some back to life,” he said.

8 . What Does the Length of Your Fingers Say About You?
Are you the peace-loving type or the ambitious go-getter? Your finger length might be a clue. Take a look at your fingers. Would you believe me if I told you that the length of your fingers in relation to one another can predict your personality? I know that it sounds like one of those silly tests you see on Facebook, but I have to admit that it is exactly correct for me. Here's how it works.
Look at your three middle fingers of your hand. Is your index finger longer than your ring finger? Is your ring finger longer than your index finger? Or are the two of the same length? Find the situation that best matches your hand and see if what follows is an accurate description of your personality.
●Longer ring finger: The Sweet Talker
If your ring finger is longer than your index finger, research shows that you're likely a charming type, and you can probably talk yourself out of any situation. Others often find this personality type irresistible and will go to great lengths to help you. You're more likely to take risks, and you're good at problem-solving. People in this category make great engineers, soldiers and crossword-puzzle solvers.
●Longer index finger: The (Over) Confident One
If your index finger is longer than your ring finger, chances are you are full of confidence—possibly even to the point of being over-confident and proud. You are not necessarily introverted（内向的）,but you do enjoy time to yourself, especially when you're trying to complete a project. You are a dream pursuer who can make things happen, but you may be shy when it comes to taking the first step in a relationship. You are also probably happy with what you have, but you're always wishing for more.
●Index and ring finger are of the same length: The Peacemaker
If your index finger and ring finger are roughly of the same length, you are likely to avoid conflict at all costs and seek to keep the peace in your relationships. You are well-organized, faithful and sympathetic. But deep down under all of that caring and peace-loving, you also have a hot-tempered side that can appear unexpectedly when you're pushed too far. You will try your hardest to avoid a fight.
How well do these descriptions match your personality? I was surprised at the accuracy in my case, but I'm not going to tell you which one it was!
1. Which of the following hand could be an engineer's hand?A． | B． |
C． | D． |
| A．How accurate the description of the test is. |
| B．The length of fingers can reveal personality. |

9 . Optimism (乐观) doesn’t mean paying no attention to things that cause stress. But when bad things happen, optimistic people are less likely to be unhappy about themselves and more likely to see the bad things as something that lasts a short time.
A new research has found a direct connection between optimism and healthier diet and exercise behaviors, as well as better heart health, a stronger immune system (免疫系统), better lung function, and lower death risk. “Optimistic people, regardless of sex, often have goals and the confidence to reach them,” Lee said. “Those goals could include healthy habits that contribute to a longer life.”
Studies find only about 25% of our optimism is controlled by our genes (基因), and the rest is up to us. It turns out we can actually train our brain to be more positive. Researchers studied the brains of monks (僧侣) and found surprising results: Tens of thousands of hours of meditation(冥思) had changed the function (机能) of their brains, which support positive qualities. And that may be key in producing the effect on the body.
There are simple mental exercises to develop an optimistic attitude. One of the most effective ways to increase optimism is called the “Best Possible Self” method. That is to imagine ourselves in a future in which we have achieved all our life goals. And keeping a diary in which we list the positive experiences we had can also help shape our attitude. Taking a few minutes each day to write down what makes us thankful can improve our view on life, too.
1. What is the meaning of Lee’s words?| A．Goals can lead to confidence. |
| B．Better lung function lowers death risk. |
| C．Optimism is connected with length of life. |
| D．Sex should be taken into consideration when studying optimism. |
| A．To lengthen their life. |
| B．To improve their brains’ function. |
| C．To prove optimism can be learned. |
| D．To show genes’ connection with optimism. |
| A．How to be a positive person. | B．How to make people thankful. |
| C．What to write about in a diary. | D．What to do to achieve the goals. |
| A．A science magazine. | B．A guidebook. |

Dementia is a brain disease that damages thinking and memory processes, which scientists call “cognitive (认知) abilities.” Dementia is difficult to treat. Taking care of someone who has dementia is extremely demanding. And the disease is very frightening to sufferers. Chris Roberts suffers from dementia. He says the worst part of living with this disease was getting lost while driving. “The worst thing that I found was getting lost in the car, not just forgetting where I was going— I wouldn’t know where I was.” More than 47 million people around the world suffer from dementia. The World Health Organization reports that 60 percent of them live in low- and middle-income countries.
We get vitamin D from some foods like nuts, lentils (扁豆) and fatty fish. We also get vitamin D from the sun. But that is not dependable. In some parts of the world, there is not enough sunlight to provide enough vitamin D. Also, sunblock prevents the vitamin from entering the body. To add to the problem, the skin’s ability to process vitamin D weakens as a person ages.
Researchers at Rutgers University in New Jersey are exploring the relationship between vitamin D and dementia. The team recently measured vitamin D levels and cognitive ability in older people. Nutritional sciences professor Joshua Miller led the team. He said cognitive abilities differed among the study subjects. He said tests showed that about 60 percent of the group was low in vitamin D.
