As the father of a student, I have experienced first hand what a great teacher is. My son was in the 4th grade last year, and he had a teacher called Miss Green. I believe that when he is an adult he will surely look back on her as the best teacher he has ever had.

    My son has attention deficit disorder(注意力缺损症) that makes it a little more difficult for him to learn.She was able to change her teaching methods for him so that he could keep up with the rest of the class. As a result, he got straight As on many subjects. She regarded her class as a family and they even had their own class song. She would often have them sing it to encourage them and develop a team spirit for them. When she saw that they were no longer listening carefully to what she was teaching, she would have them close their textbooks, stand up all around the room and throw around a small football. This helped them clear their minds and then focus on the lesson again.Besides, she was quick to reply to any phone calls or emails from us and got rid of our worries about children quickly.

    When my son went to the 5th grade this year, we happened to pass her classroom.When she saw my son, her face lit up and she came out and hugged him.She generally loves all of the children in her classroom and that love really shows.I can only pray that my son will continue to get teachers just like her for the rest of his school years.

    “Years ago when I was at the Grand Canyon, I remembered someone coming up to the canyon's edge, taking a shot with a camera and then walking away, like 'got it – done', barely even glancing at the magnificent scene in front of him,” Linda Henkel, a scientist at Fairfield University, US told Live Science.

    Henkel was surprised by how obsessed (痴迷的) people are with taking pictures these days - before dinner, during friends' birthday parties, on museum tours and so on.

    They keep taking pictures because they think that it helps record the moment, but as Henkel's latest study has just found out, this obsession may prevent their brains remembering what actually happened, reported The Guardian.

    In her study, Henkel led a group of college students around a museum and asked them to simply observe 15 objects and photograph 15 others. The next day the students' memory of the tour was tested, and the results showed that they were less accurate in recognizing the objects and they remembered fewer details about them if they photographed them.

    ''When people rely on technology to remember them — counting on the camera to record the event and thus not needing to attend to it fully themselves, it can have a negative impact on how well they remember their experiences,” Henkel explained.

    But there is also an exception: if students zoomed in to photograph part of an object, their memory actually improved, and those who focused the lens (镜头) on a specific area could even recall parts that weren't in the frame.

    So basically, this study is saying that constantly taking pictures can harm your memory. But shouldn't reviewing pictures we have taken help wake up our memories? This is true, but only if we spend enough time doing it.

    “In order to remember, we have to access and interact with the photos, rather than just collect them,” Henkel told The Telegraph. However, previous research has shown that most people never take the time to look over their digital pictures simply because there are too many of them and they aren't usually very organized on their computers.

    I grew up with a fat dad 450 pounds at his heaviest. Every week he would try a new diet, and my family ended up eating whatever strange food he was trying at that moment.

    After my third-grade year, my dad landed a life-changing job in Manhattan. My mom, my little sister and I had to move away from our hometown, Chicago, and leave my grandmother and her beautiful food behind.

    Leaving my grandmother was far more frightening than the move to New York City.  There would be no more special weekends at my grandmother's house, the only place I can remember feeling happy, safe and nourished (有营养的). It was what I desired. In this new city, I felt extremely alone and lost, and I missed my grandmother terribly.

    My grandmother knew just how I felt. And she knew the cure. Every week, she would send me a card with a$ 20 bill, a recipe and a list of what to buy at the market. It kept us bonded, and her recipes filled my body and soul.

    Over the years, I have grown to better understand my father's struggles with weight and the toll (代价) it took on him and those who love him. I have come to realize he was driven not by vanity (自负) or selfishness as much as by a deep pain, I  And in spite of growing up in such an unhealthy eating environment ( or perhaps be-cause of it), as an adult I found a passion and a career as a nutrition consultant.

    Today, my father weighs 220 pounds and is a vegan(素食者). How he got there is a story I hope to share in the coming weeks. More importantly, food is no longer a barrier that keeps us apart, but a bridge that keeps us connected. There is nothing my dad enjoys more than talking with me about dietary theories and his weightloss victories. And now I am the one regularly sending recipe cards to my father s house, just as my grandmother did for me.

    King's College Summer School is an annual (年度的) training program for high school students at all levels who want to improve their English. Courses are given by the teachers of King's College and other colleges in New York. Trips to museums and culture centers are also organized. This year's summer school will be from July 25 to August 15. More information is as follows：

At age 22, Hikari Oberman has already been a lifeguard for four years. Last week, Oberman talked to The Garden Island about how he helped save lives during a recent rescue.

On Dec. 30, Oberman and his coworker Cope were parked in their truck at Anini Beach when two workers ran up to them and said, "I think someone's getting stuck in the channel!"

"I grabbed our equipment. We started rolling out down there," Oberman said. When he got out there, Oberman found a standup paddler, a man in his late 30s, struggling against the current, with an elderly man holding tightly to the back of the paddleboard (冲浪板).

He said, "My coworker grabbed the standup guy. Meanwhile, I'm stuck with the older man. "

Normally, Oberman said he would pull the paddler up, lay him on the surfboard, climb up behind and paddle from there. He tried that technique at first and quickly realized it was not a practicable option. They are not going anywhere.

Waves hit against the extremely sharp reef very hard about 30 yards behind them, and the current was pulling them into it.

"It's right behind us. If I stop paddling, we're definitely going to be in that zone." He said.

They started making progress toward the reef, where they might safely be able to climb out. Oberman just focused on forward movement.

After about five minutes-"even though it felt longer" -Oberman said his partner had gotten the paddleboarder safely to shore and started coming back out to help.

"I look back, and I see our Jet Ski. He's finally coming in the channel. We're not going to have to worry about that now. "

It was a good rescue.

When asked what it feels like to save someone's life, Oberman responded, "I love it! That's why we do it!" But as exciting as it might be to perform a big rescue, he explained that the most important part of his job is to keep people from getting into trouble in the first place.
