He says the problem with teachers is, “What will a kid learn from someone who chose to become a teacher?” He reminds the other dinner guests that it's true what they say about teachers: Those who can, do; those who can't, teach.

    I decide to bite my tongue instead of biting his and stop myself from reminding the other dinner guests that it's also true what they say about lawyers—that they make money from the misfortune of others.

    “I mean, you're a teacher, Taylor,” he says to me. “Be honest. What do you make?”

    I wish he hadn't asked me to be honest, because now I have to teach him a lesson.

    You want to know what I make?

    I make kids work harder than they ever thought they could.

    I can make a C+ feel like a great achievement and an A－ feel like a failure.

    How dare you waste my time with anything less than your very best?

    I make parents tremble in fear when I call them:

    I hope I haven't called at a bad time,

    I just wanted to talk to you about something Billy said today.

    Billy said, “Leave the kid alone. I still cry sometimes, don't you?”

    And it was the bravest act I have ever seen.

    I make parents see their children for who they are and what they can be.

    You want to know what I make?

    I make kids wonder.

    I make them question.

    I make them criticize.

    I make them think.

    I make them apologies and mean it.

    I make them write, write, write.

    And then I make them read.

    I teach them to solve math problems that they once thought impossible.

    I make them understand that if you have brains then you follow your heart and if someone ever tries to judge you by what you make, you teach them a lesson.

    Let me make this simple for you, so you know what I say is true;

    I make a great difference! What about you?

    Astronauts on shorter shuttle missions often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day's work. This type of schedule is far too demanding for long missions on the International Space Station(ISS). ISS crew members usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, Internet phone and through private video conferences.

    While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy.  Before a mission, the family and friends of each ISS crew member put together a collection of family photos, massages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines,  photos and letters. And as from early 2010, the Internet became available on the ISS, giving astronauts the chance to do some “web surfing” in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.

    Many astronauts say that one of the most relaxing things to do in space is to look out of the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth's vast mass and oceans.

I suspect that the most basic and powerful way to connect to another person is to listen. Perhaps the most important thing we ever give each other is our attention, and especially if it's given from the heart. When people are talking, there's no need to do anything but listen to them. Just take them Just listen to what they're saying and care about it. Most times caring about it is even more important than understanding it. Most of us don't value ourselves or our love enough to know this. It has taken me a long time to believe in the power of the simply saying "I'm so sorry" when someone is in pain, and meaning it.

    One of my patients told me that when she tried to tell her story, people often interrupted to tell her that they had once had something just like that happen to them. Eventually she stopped talking to most people. She was just too lonely. We connect through listening. When we interrupt what someone is saying to let them know that we understand, we move the focus of attention to ourselves. When we listen, they know that we care. Many people with cancer can talk about the relief of having someone just listen.

    I have ever learned to respond to someone crying by just listening. In the old days I used to reach for the tissues(纸巾), until I realized that passing a person a tissue may be just another way to shut them down, to take them out of their experience of sadness and grief. Now I just listen. When they have cried all they need to cry, they find me there with them.

    As an expert on the science of sleep and sleep disorders, Michael Twery believes “People have good understanding about the necessity of sleeping 7-8 hours in bed. But they undervalue the function of napping in day.”

    For example, many Americans do nap. But one-third of adults in the US are also frequently tired. Someone who naps as a way of paying off a sleep debt may not experience the same improvements from napping as a healthy, well-rested person would.

    Also, many people may not want to admit that they take a nap. That only children, the very old, sick or lazy people nap is a common opinion. In fact, Americans sometimes do very strange things. For those who claim they only sleep five hours a night, they may think they are somehow stronger than the average human—superhuman, if you will.

    Luckily, many offices now offer napping rooms in many U. S. cities. While resting in the middle of the work day may seem like a luxury to Americans, napping is very much part of a normal, everyday life in other parts of the world.

China, generally speaking, is a land of nappers. Researchers recently looked at information provided by nearly 3, 000 Chinese adults, aged 65 years or older. Based on their answers, researchers put them into four groups: non-nappers (0 minutes), short nappers (less than 30 minutes), moderate nappers (30-90minutes), and extended nappers (more than 90 minutes).

    The study found that the hour-long nappers did better on the tests than those who napped for shorter and longer periods. Keep in mind, however, that these are the findings for those over the age of 65.

    Michael Twery notes that an hour long nap may be too long for young, healthy adults. “Currently, 30 minutes is enough to remove the pressure to sleep and will help us feel more awake. If we nap longer, we will get trapped into sleep inertia—a very deep sleep period.”

    A new discovery may change how scientists think about prehistoric humans. Human history is more of a war movie than a romantic comedy, at least as far as other animals are concerned; we may be causing one of the planet's great extinction events at the moment. But a recent discovery means humans might not be as destructive as we thought.

    Large animals have a history of disappearing when humans move to their areas. Scientists have long believed that humans simply hunted big animals because people are really good at hunting. For example, scientists thought humans arrived in Madagascar around 4,000 years ago, but only two thousand years later, giant lemurs, giant tortoises and elephant birds disappeared from the island. Many scientists thought humans had something to do with that rapid drop in biodiversity(生物多样性).

    At least, that's what scientists thought until a group of researchers dug up a lot of bones in Madagascar recently. These bones belonged to the elephant bird, a kind of extinct bird that weighed up to 1,000 pounds. The huge bones were covered in cuts that clearly came from a human hunter. The researchers found that the humans had killed the birds 10,000 years ago...Thousands of years before scientists believed humans had come to the island.

    "Our research provides evidence of human activity in Madagascar more than 6,000 years earlier than suspected, which shows that a different extinction theory is required to understand the huge biodiversity loss that has happened on the island." explained James Hansford, one of the researchers. "Humans seem to have coexisted with elephant birds and other now-extinct species for over 8,000 years, clearly with limited negative influence on biodiversity for most of this period."

    If humans lived among large animals for thousands of years without wiping them out, then maybe our species can't wipe other species out. Rather, extinction is more of a habit we've learned. Perhaps we can unlearn it too.

    Climate change, pollution, overuse of water and development are killing some of the world's most famous rivers including China's Yangtze. India's Ganges and Africa's Nile. WWF said on Tuesday. At the global launch of its report "World's Top 10 Rivers at Risk", the group said many rivers could dry out. affecting hundreds of millions of people and killing unique aquatic (水生的) life.

    "If these rivers die, millions will lose their livelihoods, biodiversity (生物多样性) will be destroyed on a massive scale, there will be less fresh water and agriculture, resulting in less food security, "said. Rayi Singh, secretary—general of WWF—India. The report, launched ahead of "World Water Day" today, also cited the Rio Grande in. the United States, the Mekong and Indus in Asia, Europe's Danube, La Plata in South America and Australia's Murray—Darling as in need of greater protection.

    Rivers are the world's main source of fresh water and WWF says about half of the available supply is already being used up. Dams have destroyed habitats and cut rivers off from their flood plains, while climate change could affect the seasonal water flows that feed them, the report said. Fish populations, the top source of protein and overall life support for hundreds of thousands of communities worldwide, are also being threatened, it found. The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization, damming and huge influxes (流入) of sediment (积淀) from land conversion.

    Climate change, including higher temperatures, also means serious consequences for fishery productivity, water supply and political security in Africa's arid Nile basin. Tributaries (支流) flowing into the Ganges are drying up because of irrigation, WWF said.
