【推荐1】One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem, while the student claimed a perfect score. I was elected as their arbiter(仲裁人). I read the examination problem：" Show how it is possible to determine the height of a tall building with the aid of a barometer(气压计). " The student had answered: "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of it is the height of the building. "

The student had really answered the question completely, but the answer didn't prove his ability in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and casually wrote one , which read "Take the barometer to the top of the building and lean it over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula(公式) to calculate the height of the building. "

At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others and then added " Probably the best is to take the barometer to the administrator and said to him ‘Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you. ’"

Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.

The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize in Physics in 1922.

On that day, I hurried to my science class in the morning and found a seat in the back. I waited there for 15 minutes before the bell rang. The science teacher told us about some class rules. No one talked to me; nor did I talk to anyone else. I was one of those very shy girls. After the science class, I had an English class. I thought it would be boring but it turned out to be very funny. When the classes of the morning ended,   I went to lunch. I sat outside the dining room with no one to talk to and no food because I was too nervous to join the lunch line. I kept looking around hoping to see someone I knew but I never saw anyone.

Lunch ended and I went to have my art class. I was the first one there and not even my teacher was there yet. So I sat at my desk and started drawing some pictures. I didn’t notice the rest of the class walking in or the girl that was standing behind me till I was surprised by the voice, “So what are you drawing?” It was a girl who had really long hair. She ended up being my best friend and one of the kindest and liveliest girls I know.

In the next class meeting, the teacher asked us to talk about the past holiday. I was glad to make some new friends in the class. The first day of high school was hard for me but I got through it.

【推荐1】We’re often reminded of the importance of preserving the planet as we see it for future generations — and children at St Oswald’s CE Primary School Chester certainly agree.

Nine-year-old Isobel Kelleher from the school’s Hummingbirds class thinks adults need to take note.“Sometimes they can be busy and I don’t think they think they can make a difference,but if everyone does a little bit it all adds up,” she tells HuffPostUK.“We started looking at plastic pollution in our oceans and the things like plastic bags that are polluting them,” she says.“Fish can eat the plastic and they can die,or we might even eat the fish ourselves.”

Mr Timms, Isobel’s teacher, has been spearheading a new project at the school which lets children loose creatively to raise the awareness of the need to be more environmentally friendly. The entire Hummingbirds class, which is made up of nine-year-old and ten-year-old pupils, has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.

Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us.“We sometimes overlook how much we can really learn from children,” he says.“It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic, and to recycle more, and even stopping them using plastic straws.”

Mr Timms is proud of his Hummingbirds class.“The message that they would like to send to world is simple:stopping this isn’t someone else’s job,and it won’t be OK if we just leave it.”

【推荐3】An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.

In addition to encouraging reading as a pursuit to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched the " If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.

In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.

The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致）can be achieved. Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.

Ultimately, as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
