1 . Investing In the Graphite (化石墨) Revolution
December 21st, 2014
Graphene (石墨烯) is the future. Plain and simple.
Its 200 times stronger than steel, thinner than a sheet of paper, and more conductive than copper.
And that’s not all…
Researchers all over the world are using it for critical advances in a variety of industries. Graphene makes:
·Solar cells — 50x～100x more efficient
·Semiconductors — 50x～100x faster
·Aircraft — 70% lighter
We’re talking about batteries that charge 10x faster and store 10x more power…
Phones and computer displays that bend and fold…
It’s so vital to our future that it’s been named a “supply critical mineral” and a “strategic mineral” by the United States, Japan and the European Union.
Yet only a few companies around the world have access to mineral resource that is required to make graphene. And 70% of supply is controlled by China.
So the setup is perfect for any non-Chinese supply to become an extremely profitable investment, just like rare earths a few years ago.

2 . Millions of years ago dinosaurs lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry, and the forests there died. Then dinosaurs could not find enough to eat. This must be one reason why dinosaurs died out.
We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs.
There may be other reasons that we don’t know about yet. Scientists are trying to make more discoveries about dinosaurs.
Dinosaurs have many sizes and shapes (形状). Some were as small as chickens, while some were about 90 feet long.
There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the footprints (足迹) that fights did take place.

3 . The giant panda’s special black-and-white fur makes it one of the most recognizable animals on the planet. But why does it have this unique coloring? To hide from natural enemies, both in the snow and in the shadows, study lead author Tim Caro, a professor in the Department of Wildlife, Fish & Conservation Biology at the University of California, Davis, said in a new statement. Moreover, the large black circles around a panda’s eyes may help other pandas recognize it, the researchers said.
Understanding why the giant panda has such noticeable color has been a long-term problem to solve. To find out the answer, Caro and his colleagues looked at photos of pandas and 195 other carnivore(食肉动物) species, including 39 subspecies of bear. Then, they recorded the coloring on each area of those animals’ bodies, and compared them with areas of the panda’s body. “Compared with the previous studies, the breakthrough in this study was treating each part of the body as an independent area,” Caro said.
The research team tried to figure out the purpose of the dark-colored furry areas. After going through many comparisons, the researchers determined that the white parts of the giant panda help it hide in the snow. In contrast, its black arms and legs help it hide in the shadows, they said. The panda’s white-and-black coloring didn’t appear to be related to temperature regulation. Nor did they find evidence that the dark circles around a panda’s eyes helped to make them look cuter.
“This really was a great effort by our team, finding and scoring thousands of images and scoring more than 10 areas per picture from over 20 possible colors,” study co-author Ted Stankowich, an assistant professor of biology at California State University, Long Beach, said in the statement. “Sometimes it takes hundreds of hours of hard work to answer the simplest question: Why is the panda black and white?”

5 . “Hello Mother, Dad, and Blanche,” a quiet voice, has clearly been played many times over. “How’s everything at home? I’m recording this from Dallas…” The disc is small, seven inches across, dated October 1954. The old label shows that the speaker’s name is “Gene”. Gene suggests in his minute-long message that he is traveling and tells his family not to worry about him.
This forgotten sound is one of the world’s early “voice mails”. During the first half of the 20th century, these “voice mails” and other messages were recorded largely, pressed onto metal discs and vinyl records (黑胶唱片) and mailed in places all over the world. When Thomas Edison invented the phonograph (留声机) in 1877, he expected a device that could reproduce music and even store languages.
The gramophone, a later form of the phonograph developed by Emile Berliner in 1887, provided a first possibility for recorded sound being used for long distance communication. The practice of sending “voice mails” really got going across the world in the 1930s and 1940s. Back then, families could listen to the messages on repeat — gathering together around the record player whenever one arrived. They could play it proudly again anytime there were guests, but with each play, the needle would scrape away at the grooves (凹槽) until the message could hardly be heard any longer.
Today at Princeton University, professor Thomas Levin is trying to store these sounds of the past. Linguists (语言学家) are particularly interested in “voice mails” because it provides some of the earliest-ever recorded samples of how regular people spoke — their conversational vocabulary, their pronunciation and accents, their sentence structure and their intonation (语调).

6 . For lots of kids, toddlerhood (幼儿期) is an important time for friendship. Studies show that the earlier kids learn to form positive relationships, the better they are at relating to others as teenagers and adults. Playing together also helps these kids practice social behaviors, such as kindness, sharing, and cooperation.
Even so, how quickly your child develops into a social creature may also depend on his temperament(性格). Some toddler s are very social, but others are shy. In addition, the way that toddlers demonstrate that they like other children is markedly different from what adults think of as expressions of friendship. Research at Ohio State University in Columbus found that a toddler’s way of saying “I like you” during play is likely to come in the form of copying a friend’s behavior.
This seemingly unusual way of demonstrating fondness can result in unpleasant behavior. Regardless of how much they like a playmate, they may still grab his toys, refuse to share, and get bossy. But experts say that this is a normal and necessary part of friendship for kids this age. Through play experiences, toddlers learn social rules. That’s why it’s so important to take an active role in your toddler’s social encounters by setting limits and offering frequent reminders of what they are. When you establish these guidelines, explain the reasons behind them.
Begin by helping your child learn sympathy (“Ben is crying. What’s making him so sad?”), then suggest how he could resolve the problem (“Maybe he would feel better if you let him play the ball.”). When your child shares or shows empathy(同理心) toward a friend, praise him (“Ben stopped crying! You made him feel better.”).
Another way to encourage healthy social interaction is by encouraging kids to use words- not fists-to express how they feel. It’s also important to be mindful of how your child’s personality affects playtime. Kids are easy to get angry when they’re sleepy or hungry, so schedule playtime when they’re refreshed.

7 . There are many ways in which a person’s body language can give you information about whether they are lying or not.
One of the biggest signs that a person is telling lies is that he avoids eye contact during conversation. He may also touch his face often, covering his mouth with his hand very often. Touching the nose is also said to be a sign of taking others’ attention to cover up lies. A person who is not telling the truth may be trying to make you focus on his actions rather than his words.
When a liar (说谎者) tells lies, his physical expression is often very stiff (僵硬的). If he is smiling as he speaks, only the mouth will move. A real smile naturally causes movement of the mouth, eyes, forehead, cheeks, and jaw.
The liar’s hand, leg and arm movements are toward his own body. He takes up little space. The person’s body language is closed off. Liars do not look relaxed, even though they may be trying to give the impression that they are.
When explaining something, a liar usually feels uncomfortable with pauses (停顿) or silences. The person may speak gently or in disordered words. A very skillful liar is able to speak directly and with confidence. In fact, some salespeople are best at this skill.
If you doubt someone is lying, change the topic of conversation suddenly. The liar will willingly change topics with you and become more relaxed. A person who is telling the truth will generally become confused by this sudden change. Another sign of someone telling a lie is yawning (哈欠) — the person may try and look as relaxed as possible, and yawing and stretching are ways of achieving this.
1. Why do liars often cover their mouths?| A．To show their own skill. | B．To avoid the mouth’s stiffness. |
| C．To smile because they feel shy. | D．To change the listener’s attention. |

8 . On an ordinary fossil-hunting (化石搜寻) outing, the members of the Hamilton Junior Naturalist Club might expect to find a few interesting shells (壳). But on a 2006 trip to Kawhia Harbour in New Zealand’s North Island, the students discovered the bones of a fossilized huge penguin (企鹅).
“We were expecting to find common fossils — shells, but were hugely shocked to find a huge animal skeleton (骨架) just lying on the beach,” said Mike Safey, president of the club.“Our club’s fossil expert Chris Templer realised immediately that we had discovered something hugely important. We made the decision to rescue this fossil, otherwise it would have been completely destroyed by weather.”
Researchers from Massey University used 3D scanning to compare the fossils to digitalized bones from all over the world. The penguin fossil is between 27.3 and 34.6 million years old, according to Daniel Thomas, a senior lecturer in Massey’s School of Natural andComputational Sciences. It is similar to Kairuku penguins but with longer legs. Researchers named it “Kairuku waewaeroa” for this characteristic.
Around 1.4 meters tall, this penguin was much huger compared to living penguins. We know that body size can be an important factor when thinking about ecology. How and why did penguins become huge, and why aren’t there any huge penguins left? Well-preserved fossils like Kairuku waewaeroa can help us answer these questions.
“The discovery is important for researchers, and it was also rewarding for the students who found it and encourages other young people to go out in nature and make their own discoveries. It reminds us that ancient New Zealand had many kinds of birds, and emphasizes how important New Zealand is for bird diversity today,” Thomas says.

10 . The cultivation of plants by ants is more widespread than previously realized, and has evolved on at least 15 separate occasions.
There are more than 200 species of ant in the Americas that farm fungi (真菌) for food, but this trait evolved just once sometime between 45 million and 65 million years ago. Biologists regard the cultivation of fungi by ants as true agriculture appearing earlier than human agriculture because it meets four criteria: the ants plant the fungus, care for it, harvest it and depend on it for food.
By contrast, while thousands of ant species are known to have a wide variety of interdependent relationships with plants, none were regarded as true agriculture. But in 2016, Guillaume Chomicki and Susanne Renner at the University of Munich, Germany, discovered that an ant in Fungi cultivates several plants in a way that meets the four criteria for true agriculture.
The ants collect the seeds of the plants and place them in cracks in the bark of trees. As the plants grow, they form hollow structures called domain that the ants nest in. The ants defecate (排便) at designated absorptive places in these domain, providing nutrients for the plant. In return, as well as shelter, the plant provides food in the form of fruit juice.
This discovery prompted Chomicki and others to review the literature on ant-plant relationships to see if there are other examples of plant cultivation that have been overlooked. “They have never really been looked at in the framework of agriculture,” says Chomicki, who is now at the University of Sheffield in the UK. “It’s definitely widespread.”
The team identified 37 examples of tree-living ants that cultivate plants that grow on trees, known as epiphytes (附生植物). By looking at the family trees of the ant species, the team was able to determine on how many occasions plant cultivation evolved and roughly when. Fifteen is a conservative estimate, says Campbell. All the systems evolved relatively recently, around 1million to 3 million years ago, she says.
Whether the 37 examples of plant cultivation identified by the team count as true agriculture depends on the definitions used. Not all of the species get food from the plants, but they do rely on them for shelter, which is crucial for ants living in trees, says Campbell. So the team thinks the definition of true agriculture should include shelter as well as food.
