So many of us hold on to little resentments that may have stemmed from an argument, a misunderstanding, or some other painful event. Stubbornly, we wait for someone else to reach out to us―believing this is the only way we can forgive or rekindle(重新点燃) a friendship or family relationship.

    An acquaintance of mine whose health isn't very good, recently told me that she hasn't spoken to her son in almost three years. "Why not" I asked. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she resisted initially and said, "I can't do that. He's the one who should apologize." She was literally(简直) willing to die before reaching out to her only son. After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and sincerely said sorry to her. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger we turn "small thing" into "big thing" in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go as well as the joy of letting others be right. You'll also notice that as you reach out and let others be "right" they will become less defensive and more loving toward you. They might even reach back. But if for some reason they don't that's okay too. You will have the inner satisfaction of knowing that you have done your part to create a more loving world and certainly you'll be more peaceful yourself.

    Mom was a teacher most of her life. When she wasn't in the classroom, she was educating her children or grandchildren; correcting our grammar; starting us on collections of butterflies, flowers or rocks; or inspiring a discussion on her most recent “Book of the Month Club” topic. Mom made learning fun.

    It was sad for my three brothers and me to see her suffering in her later years. At eighty- five, she suffered a stroke and she went steadily downhill after that.

    Two days before she died, my brothers and I met at her nursing home and took her for a short ride in a wheelchair. While we waited for the staff to lift her limp body back into bed, Mom fell asleep. Not wanting to wake her, we moved to the far end of the room and spoke softly.

    After several minutes our conversation was interrupted by a muffled sound coming from across the room. We stopped talking and looked at Mom. Her eyes were closed, but she was clearly trying to communicate with us. We went to her side.

    “Whirr,” she said weakly.

    “Where?” I asked. “Mom, is there something you want?” “Whirr,” she repeated a bit stronger. My brothers and I looked at each other and shook our heads sadly.

    Mom opened her eyes, sighed, and with all the energy she could gather said, “Not ...was. Say were!”

    We suddenly realized that Mom was correcting Brother Jim's last sentence. “if it was up to me…”

    Jim leaned down and kissed her cheek. “Thanks, Mom,” he whispered. We smiled at each other and once again shook our heads.

    Linda Eveans was my best friend—like the sister I never had. We did everything together: piano lesson, movies, swimming, and horseback riding.

    When I was 13, my family moved away, Linda and I kept in touch through letters， and we saw each other on special times, like my wedding and Linda's. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped "Address Unknown". I had no idea about how to find Linda.

    Over the years, I missed Linda very much, I wanted to share happiness of my children and then grandchildren, And I needed to share my sadness when my brother and then mother died, There was an empty place in my heart that only a friend like Linda could fill.

    One day, I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman—Linda's married name. "There must be thousands of Wagmans." I thought, but I still wrote to her.

    She called as soon as she got my letter, "Mrs, Tobin!" she said excitedly, "Linda Evans Wagman is my mother." Minutes later I heard a voice that I recognized at once, even after 40 years. We laughed and cried and caught up on each other's lives. Now the empty place in my heart is filled. And there's one thing that Linda and I know for sure: we won't lose each other again!

    University Room Regulations

    Approved and Prohibited Items

    The following items are approved for use in residential (提供住宿的) rooms: electric blankets, hairdryers, personal computers, radios, televisions and DVD players. Items that are not allowed in student rooms include: candles, ceiling fans, fireworks, waterbeds, sunlamps and wireless routers (路由器).Please note that any prohibited items will be taken away by the Office of Residence Life.

Access to Residential Rooms

    Students are provided with a combination (组合密码) for their room door locks upon check-in. Do not share your room door lock combination with anyone. The Office of Residence Life may change the door lock combination at any time at the expense of the resident if it is found that the student has shared the combination with others. The fee is $25 to change a room combination.

Cooking Policy

    Students living in buildings that have kitchens are only permitted to cook in the kitchen. Students must clean up after cooking. This is not the responsibility of housekeeping staff. Kitchens that are not kept clean may be closed for use. With the exception of using a small microwave oven to heat food, students are not permitted to cook in their rooms.

    Pet Policy

    No pets except fish are permitted in student rooms .Students who are found with pets, whether visiting or owned by the student, are subject to an initial fine of $100 and a continuing fine of $50 a day per pet. Students receive a written notice when the fine goes into effect. If, one week from the date of the written notice, the pet is not removed, the student is referred to the Student Court.

Are we alone in the universe? A team of scientists announced on January 6, 2015 that they had identified eight planets beyond our solar system, three or four of which orbit in their stars' "Goldilocks Zone" — the region where temperatures are not too hot or too cold for water, which is a necessary ingredient for life as we know it, to exist liquid form. This may be good news for people hoping that Earth is not the only inhabited world in the universe.

    The scientists, led by Dr. Guilermo Torres of the Harvard-Smithsonian Center for Astrophysics, made the discoveries using data collected by the planet-seeking Kepler telescope.

    NASA launched Kepler in 2009. Since then, the telescope has identified more than 1,000 planets outside of our solar system. Torres and his team analyzed the data about the eight newly discovered world to determine which ones are most likely to be similar to our Earth.

    Among the new discoveries, the scientists say the planets called Kepler438b and 442b are the closest to Earth. Kepler 438b is just about 10% larger than our planet, and gets 40% more of its energy from its star than Earth receives from the Sun. Temperatures there would be about 140 degrees. Kepler 442b is about 33% larger than Earth, but receives 30% less energy from its star. That would make it a potentially chillier world than our own. Torres says it is possible for life to exist and survive in either of those temperatures, but for that to happen, these planets would need to have another key ingredient for life: a heat-trapping atmosphere like Earth's.

    While these findings add to the possibility that life exists beyond Earth, Torres cautions against drawing conclusions, “We are not claiming they are inhabited,” he says. In fact, these planets are so far away that the scientists cannot observe them directly, which can be explanation for why for now it remains unknown whether these planets contain life. But the discovery of planets in their stars' habitable zones suggests that somewhere out there, some form of alien life may have taken hold.

When adult humans meet a baby, many can't help speaking in a higher-pitched (更高音的) and sing-song y voice. This shift, known as parentese, is not unique to humans. It has also been observed in animals like monkeys and gorillas. Now, scientists are adding one more species to that list: bottle-nose dolphins.

Dolphins are intelligent animals that live and hunt in groups. They communicate in a unique way: Every individual produces its own signature sound that acts much like an ID card, usually by its first birthday. But how does each come up with its distinctive whistle? For babies, it might have something to do with listening to Mum. To solve this mystery, researchers examined the sounds mother dolphins make.

Scientists studied 34 years' worth of recordings of sounds made by 19 female bottle-nose dolphins. When the mother dolphins were near their young, they continued to make their signature sounds, but at a higher frequency. They also used a wider range of frequencies than they did when their babies were not nearby.

This discovery suggests that using these modifications, mother dolphins assist their young in learning how to produce these calls themselves. Since baby dolphins often spend some years with their mothers before living on their own, it makes sense that this adaptation would help them learn to communicate. At the very least, the higher-pitched whistle likely gets the babies' attention. "It's important for a baby to know, ‘Oh, Mum's talking to me now,'" says marine biologist Janet Mann.

This kind of research could help us understand how language developed in humans. "It is absolutely essential to have basic knowledge about other species and how they communicate," says Mann. "I would be really interested to see whether dolphins also change their sounds when interacting with babies of others, which is what happens in humans."
