Grey clouds move as low as smoke over the treetops at Lolo Pass. The ground is white. The day is June 10.It has been snowing for the past four days in the Bitterroot Mountains.Wayne Fairchild is getting worried about our trek over the Lolo Trail-95 miles from Lolo Montana to Weippe in Idaho, across the roughest country in the West. Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo.Today Fairchild is nervously checking the weather reports.He has agreed to take me across the toughest,middle section of the trail.

    When Lewis climbed on top of Lemhi Pass,140 miles south of Missoula,on Aug.12,1805,he was astonished by what was in front of him;“high mountain chains still to the West of us with their tops partially covered with snow.”Nobody in what was then the US knew the Rocky Mountains existed,with peaks twice as high as anything in the Appalachians back East.

    Today their pathway through those mountains holds more attraction than any other ground over which they traveled,for its raw wilderness is an evidence to the character of two cultures:the explorers who braved its hardships and the Native Americans who prize and conserve the path as a sacred (神圣的)gift. It remains today the same condition as when Lewis and Clark walked it.

    The Lolo is passable only from July to mid-September.Our luck is holding with the weather,although the snow keeps getting deeper.As we climb to Indian Post Office,the highest point on the trail at 7,033 ft,we have covered 13 miles in soft snow,and we hardly have enough energy to make dinner.After a meal of chicken,I sit on a rock on top of the ridge (山脊）.There is no light visible in any direction,not even another campfire.For four days we do not see another human being.We are occupied with the things that mix fear with joy.In our imagination we have finally caught up with Lewis and Clark.

    When I started teaching at school, I was sure I would change the world and touch children who needed love.

    Although my students seemed to respond pretty well to my teaching , there was a small group of girls who became more and more hostile towards me.

    One day a fight happened in my classroom. Trying to end it, I stepped in to face one of these hostile young women, who started hitting me in the face. Two boys jumped up to control the girl, but the damage was done.

    While the girl was suspended for a few days, I was determined that she would not return to my classroom. But I also prayed. I wanted to see all the students right there in my daily work at school.

    On the top of my daily lesson-plan book, I wrote this statement, “To see all the children in my classroom is always beautiful.” With this view I could expect to heal any anger towards the girl in my heart.

    After her suspension, she returned to my classroom. The student's young mother was trying to raise six children while her husband was away in the war. The mother and I agreed to work together to help her oldest daughter.

    There were no more incidents of anger the rest of the year. In fact, in the seven years I remained at that school, I taught all six of this family's children. When the youngest was in my class, the mother told me, “Our family love you. Every year one of my kids says, ‘I hope I'm in her class!'”

    The standard of seeing each of my students as a perfect one was the best teaching tool I had, and led to success.

Everyone has got two personalities—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control yourself, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you fall asleep with.

    If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to upset people. So you never express your real feelings. You're quite shy and you aren't very confident.

    If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you're always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not tomorrow.

    If you sleep curled up(卷曲), you are probably a very nervous person. You have a low opinion of yourself and you often protecting yourself from being hurt, so you are very defensive. You're shy and you don't usually like meeting people. You prefer to be on your own. You're easily hurt.

    If you sleep on your side, you have usually got a well-balanced(平衡的) personality. You know your strengths and weaknesses. You're usually careful. You believe in yourself. You sometimes feel anxious, but you don't often get unhappy. You always say what you think, even if it makes people rather angry.

    Babies made from three people approved in UK

Babies made from two women and one man have been approved by the UK's fertility regulator. The historic and controversial move is to prevent children being born with deadly genetic diseases.

    Doctors in Newcastle - who developed the advanced form of In Vitro Fertilization or IVF (人工授精) - are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.

    Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.

The diseases are passed down from only the mother so a technique using a donor egg as well as the mother's egg and father's sperm has been developed.

    The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.

    "It is a decision of historic importance," said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA)."I'm sure patients will be really pleased by what we've decided today."

    But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) 'designer' babies.

    The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.

    Prof Mary Herbert, from the Newcastle Fertility Centre, said: "It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases.

    "Now that that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children."

    Prof Sir Doug Turnbull, the director of the Wellcome Centre for Mitochondrial Research at Newcastle University, said: "We are delighted by today's decision. We will also provide long-term follow up of any children born."

    NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.

    Through your childhood and, let's be honest, most of your adult life, you may have wondered—how do you get to Sesame Street? After 50 years, the answer has finally been revealed.

    New York City's Official Sesame Street

    In the past, there was guessing about the true location of the street, like Harlem or Alphabet City since both neighborhoods resembled Sesame Street in appearance and population makeup. Recently, in honor of the children's television show's 50th anniversary, New York City Mayor Bill de Blasio declared that West 63rd Street between Central Park West and Broadway will now officially be known as Sesame Street, close to the Sesame Workshop office.

    A Year-long Celebration for the 50^th Anniversary

    Since 1969, the children's television show Sesame Street has been a pioneering force in media and education, dealing with issues like racism, loss, poverty and living with a disability. With a mission to help kids everywhere grow smarter, stronger, and kinder, Sesame Street has brought the life-changing benefits of early learning to children across the globe for 50 years. Today, we reach kids in 150 countries and 70 languages and we're celebrating our landmark anniversary with fans and families all year long!

    Events and Activities Throughout 2019

    Fans and families around the world can join their favorite furry friends in celebrating Sesame Street's past, present, and future, with:

    A 50th television season which focuses on the power of possibilities, empowering kids to take safe risks and learn from their mistakes.

    A nationwide road trip where Sesame Street characters and friends host community events in ten cities around the country.

    A research report that will explore an important issue facing kids and families today.

    Celebrity and fan-fueled social media campaigns showcasing favorite Sesame Street memories.

    New corporations across fashion, lifestyle, and themed entertainment for fans of all ages.

    A November star-studded prime-time special, whose contents include new takes on classic scenes and visits from Sesame Street icons.

    A name is more than just a word. It carries the weight of a person's whole identity. A name can represent a person's ethnicity (种族身份) and culture, or show respect for their ancestral roots. A self-given name may represent a person's beliefs or chosen identity.

    Everyone has the right to have their name pronounced correctly. It is a sign of respect for a person's individuality. "A person's name is to him or her the sweetest and most important sound in any language," Dale Carnegie writes in his book How to Win Friends and Influence People. Behind each name is a story, and when a name is anglicized (英语化), mispronounced, or ignored, that story is dismissed.

    A name mispronounced for a long time can negatively impact a person's attitude toward their own identity. It can create feelings of shame or embarrassment because they are made to feel like a burden. In the long term, this might cause someone to distance themselves from their roots. They may begin shying away from their native language, culture, and family for the sake of fitting in.

    In order to avoid this, many international students living in the U.S. choose English names. People shouldn't have to ignore their identities for the sake of someone else's convenience.

    Everyone makes mistakes, and not everyone can get a name right on the first try. Mispronouncing a name repeatedly, however, shows a lack of effort. It is not okay to be comfortable with mispronouncing names, and being unfamiliar with a language is no excuse.

    If you're unsure whether you're pronouncing a name correctly, just ask. Think of it as a way to expand and strengthen understanding, both personally and culturally. When meeting someone for the first time, make sure that you heard the name correctly. It doesn't take a lot to simply repeat the name back. Spell it out. Write it down. Do whatever you have to do to get the name right. Making the effort to correctly pronounce someone's name is an essential part of cultural competency (文化素养). Without this, we cannot expect to show respect and tolerance for our diverse community.
