Last summer, as part of my high school graduation project, I volunteered at Saunders House nursing home .I choose this experience because it was something that I had never done before and I wanted to lend a helping hand．At first it was challenging because I was extremely shy. My goal in volunteering was to bring a smile to the residents（住客） by doing different activities from word games to playing chess. I feel as if I had accomplished that goal.

    At the nursing home, I did a lot of different activities with the residents ranging from Jeopardy to Wheel of Fortune. One of my favorites was a word game where I would write a ten -letter word on the board and the residents would try to come up with as many smaller words as possible. I could tell that it was one of their favorite games because they always seemed to be so enthusiastic when they played．I also transported residents to and from their rooms when they needed help; and whenever it was a nice day out, I would take them outside to get some fresh air and relax. On Saturday mornings, I would deliver the newspaper to the residents and on Sundays, I assisted with morning church services.

    The most unforgettable part of this experience was when I had one-on-one conversations with the residents. It was incredible how many great stories they had to tell. Their stories were so interesting and the experience was unforgettable for me .

    Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there's no need for a lot of scientific terms or expensive lab equipment. You only have to share your children's curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we're finished with your lists, do you have questions of your own about science?”

    After a long pause, a boy raised his hand, “Have you ever seen a grasshopper （蚱蜢）eat? When I try eating leaves like that, I get a stomachache. Why?”

    This began a set of questions that lasted nearly two hours.

    Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers.

    Thirdly, watch your language. Once you have a child involved in a science discussion, don't jump in with “That's right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That's interesting” or “I'd never thought of it that way before”, or coming up with more questions or ideas.

    Never push a child to “Think”. It doesn't make sense, children are always thinking, without your telling them to. What's more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.

    Lastly, show; don't tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass（放大镜）, and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates（蒸发）, set a pot of water to boil and let them watch the water level drop.

    It is widely acknowledged that it is by no means an easy task to bring up a child well. And our ancestors already understood it well. As an old proverb says, “It takes an entire village to raise a child.” That is being quoted more and more often these days. And I'm pleased about that.

    Parents need to be involved in their children's education in many ways. Helping children with homework and studying, going on a field trip, teaching a craft or coaching a child's sports team are all great ways to be involved with your child's education. And don't forget to communicate with teachers—they need and respect your input. Studies show that children learn more and schools function better when parents and schools work together.

    Communities can help children create and achieve new goals. There are other ways such as helping with homework. reading to a child, coaching a children's team, providing emotional support, helping solve problems and building self-esteem（自尊）. Kids need role models and advisers can be role models by sharing their experiences and wisdom.

    Businesses can also help shape our children's future—invite a class from your local school to visit your workplace. You may be providing a glimpse that opens a new world of possibilities. Show students what goes on during a typical day. Give a mini course for students: how products are made; how machinery works. You may have a developing electrician, a teacher, a nurse, or even a newspaper reporter on your hands.

    It really does lake an entire village to raise a child. So share the responsibility－and the joy—of bringing a child to his or her full potential.

    When I was about twelve, I headed to a restaurant for dinner with my family. It was winter, and on that night, the wind was really blowing hard.

    As my mom and I headed to the restaurant from our car, a girl about my age and her mother came up to us. They asked if we had any spare change. My mom right away asked where they lived. They pointed to an old car in a parking lot across the street. The girl said there were six of them living in that car.

    My mom said she had something to do after handing the people a few dollars. She sent me inside the restaurant with my dad and my three siblings (兄弟姐妹). But she didn't come. Later, I found out she had gone home and put all the food in our cupboards into a few bags. Then, she brought that food over to the car and handed the bags to the family. I wasn't there when that happened, but I can only imagine the joy it brought to those people.

    A few days later, when I actually found out about what she had done, I asked her why she helped those people. She told me that they were not lucky. I remember the face of that girl who had asked us for change. She was the same age as me, yet we looked so different.

    Here I stood, dressed in almost new clothes, headed to eat in a restaurant and then back home to the bedroom I shared with my younger sister. I remember thinking that the other girl didn't have any food to eat and she was heading back to a cold car shared with five other people.

    After painting this picture in my mind, I understood why my mom had done what she did. I will never forget what she did that night, and how she taught me one of the best lessons I ever learned.

    Scientists are trying to save Puerto Rico's endangered Amazon parrots after Hurricane Maria destroyed the birds' habitats and food sources(来源).

    El Yunque is a large national forest on the eastern part of Puerto Rico. Just two of the 56 wild parrots that once lived there survived Maria, the Category-4 storm that struck Puerto Rico in September 2017. Scientists report other forests have seen great drops in parrot populations as well.

    In the 1800s, there were more than a million of the bright green parrots living in the wild in Puerto Rico. By the 1970s, the number was down to just 13 birds after years of forest clearing.

    A special program was started in 1972 to help increase the parrot population, which led to the creation of three breeding(繁殖) centers. Just weeks before Hurricane Maria hit, scientists counted 56 wild parrots at El Yunque. That was the highest number in the program's history. Scientists say that even though several parrots have been born in captivity(笼养) and in the wild since Maria, the species is still in danger.

The Puerto Rican Amazon is the island's only remaining native parrot. More than 460 of the birds are kept inside the breeding centers at El Yunque and the Rio Abajo forest. Scientists have not released(释放) any of the birds since Hurricane Maria. A third breeding center, in a forest in the western area of Maricao, has not been in operation since the storm.

    Scientists are considering whether to catch some of the remaining wild parrots and put them in the same cage as the birds that are set to be released. This way, the captive birds can learn from the wild birds how to survive in the forests. Another consideration is to release some captive parrots in Maricao, which was not as heavily damaged by Maria.

    The impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.

    A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude. When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.

    Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself？Your abilities? Your interest in the job？

    Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.

    Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain:

    "I'm sorry, but I didn't catch that."

    "Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.

    At the end of the interview, thank the interviewer for her or his time. It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.

    Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.

Good luck!
