13．Your name in gold
　　Anne sat at the breakfast table, eating her cornflakes and reading the print on the cereal (谷物) box in front of her. "Great new offer!", the box read, "see back of box for (1)      ."
　　Anne's older sister Mary sat across from her, reading the other side of the cereal box. "Hey, Anne," she said , "look at this amazing prize — 'your name in gold' "
　　As Mary read on, Anne's (2)       in the prize grew. "we will send you a special pin with your name spelled in gold. Only one per family, please."
　　"That's a neat idea," she said "A pin with my very own name spelled out in gold, I'm going to (3)       in for it."
　　"Sorry , Anne, I saw it first," said Mary, "so I get first dibs (权利) on it."
　　"But I want a pin like that, so (4)      " said Anne, "please let me have it!"
　　"Nope." Said her sister.
　　"You always get your way — just because you're older than me," said Anne. Her lower lip trembling as her eyes filled with tears, "Just go ahead and send in for it. See if I (5)      ." she threw down her spoon and ran from the kitchen.
　　Several weeks passed . One day the mailmen brought a small package (6)       to Mary, Mary took the package to her room. Anne casually followed her in and sat on the bed.
　　Mary slowly took the paper off the package. She opened a little white box and carefully (7)       off the top layer of white cotton.
　　"Oh It's beautiful!" Mary said. "just like the cereal box said 'your name in gold' four beautiful letters. Would you like to see it Anne?"
　　"No, I don't care about your dumb old pin."
　　Mary put the white box on the dresser (梳妆台) and went downstairs.
　　Anne was (8)       in the bedroom. Soon she couldn't wait any longer. As she looked in the small white box . she gasped.
　　There on the pin were four beautiful letters — her name in gold: A-n-n-e.

　　I had a friend named Jenny. One day we had a really difficult math exam. All of us felt like we had not passed. When the exam results came out, I was surprised to find that I got an A, but she got a D. She accused(指责) me of copying someone else's paper. I was really angry at that time, but we're still friends now.
　　I was really angry at that time, but we're still friends now.

　　I had a good friend. We always played happily together. But one day I was walking upstairs in front of her. I wanted to play a joke on her. I leaned (倚靠) on her gently, But to my surprise she didn't help me stay standing. I was disappointed with her, and our friendship came to an end.

　　Last summer vacation, my friend and I traveled together. Sometimes he acted a bit selfishly. Later , we talked with each other about this problem. I realized that everyone has his or her own merits (优点) and defects (缺点), We must treat them properly. So we are still friends today.

15．Passing happiness on
　　I was standing in the checkout line behind a woman who looked to be in her 60s. When it was her turn to pay, the cashier (收银员) greeted her by name and asked her how was she doing?
　　The woman looked down, shook her head and said "Not so good. My husband just lost his job and my son is up to his old tricks again. The truth is, I don't know how I am going to get through the holidays."
　　Then she gave the cashier food stamps.
　　My heart ached. I wanted to help but didn't know how . Should I offer to pay for her groceries. ask for her husband's resume (简历).
　　As I walked into the parking lot, I spotted the woman returning her shopping cart. I remembered something in my purse that I thought could help her. maybe it would make her life better.
　　My heart pounded as I approached (逐渐靠近) the woman.
　　"Excuse me," I said , my voice trembling a bit. "I couldn't help overhearing what you said to the cashier. It sounds like you're going through a really hard time right now. I'm so sorry . I'd like to give you something."
　　I handed her the small card from my purse.
　　When the woman read the cards only two words, she began to cry . And through her tears, she said, "you have no idea how much this means to me."
　　I was a little startled (吓一跳) by her reply. Having never done anything like this before, I didn't know what kind of reaction I might receive. All I could think to say was: "Would it be okay to give you a hug?"
　　After we embraced, I walked back to my car and began to cry, too.
　　The words on the card?
　　"You Matter."
　　A few weeks earlier, a colleague gave me a similar card as encouragement for a project I was working on. When I read the card. I felt a warm glow spread inside of me. Deeply touched. I ordered my own box of You Matter cards and started sharing them.

16．　　It happens every spring. Flowers suddenly burst out everywhere on the same day as if they were in tune with one another. But how exactly do plants "know" when to flower?
　　It is a question that has puzzled biologists for years. But according to Science Daily, a US research group may have finally answered it — the secret lies in the protein called FKF1. This allows plants to sense the differences in day lengths so that they can tell the seasons are changing.
　　Researchers spotted the FKF1 protein when they were studying a plant called Arabidopsis. We found that the FKF1 protein is a photoreceptor (感光器). This means it is sensitive to , and can be activated by sunlight.
　　Plants produce the protein every day in the late afternoon throughout the year. If there is no light at this time. for example, in winter, when the sun goes down early, the protein won't be activated. But when spring comes and the days get longer, the FKF1 protein can be activated by daylight as the plants "know" it is time to flower. "The presence of light in the late afternoon is the signal for plants that the days are getting longer and that it is the best time for flowering." explained Pakato Imaizumi assistant professor at the University of Washington and leader of the study.
　　The daylight-sensing system also keeps plants from flowering when conditions are poor for growing, such as during autumn or winter. When the weather is cold and days are short.
　　Although researchers have only studied how the FKF1 protein works in the Arabidopsis, they believe that the process is similar in many other more complex (复杂的) plants. including crops like rice and wheat. This could be useful to the agricultural industry.
　　"If we can control the timing of flowering, we might be able to increase crop yield by quickening or delaying this." Imaizumi said "Also, if we could control the timing of flowering in horticultural plants. they may be worth more commercially (商业上)."
　　New technology based on this research might also lead to higher use of biofuel (生物燃料) plants. This would be helpful for providing energy.

17．Food for thought
　　It's hard to turn down hamburgers, French fries , potato chips. And all of the other junk food that seemed to call out to us. However, eating too much junk food can harm your body, particularly if you are between the ages of 10 and 19.
　　"Junk food shapes adolescent (青春期的) brains in ways that impair their ability to think, learn and remember. It can also make it harder to control impulsive (冲动的) behaviors." Said Amy Reichelt, a brain and nutrition specialist at Western University, Canada. "It may even up a teen's risk of depression (抑郁) and anxiety."
　　Reichelt and two other researchers reviewed more than 100 studies, including their own about how poor food choices can impact adolescent brains. They found adolescents are more sensitive than any other age group to processed (经过加工的) foods with a lot of fat and sugar and their brains are not yet fully formed.
　　Adolescent brains are still developing the ability to assess risks and control actions. The prefrontal cortex (前额皮质) is a part of brain that tells us we should not eat chips all the time and helps us resist the urge. However, this region is the last to mature — it doesn't fully develop until we are in our early 20s.
　　Meanwhile, teen brains get more buzz (兴奋) from rewards. The parts of the brain that makes us feel good when we do something pleasurable — like eating tasty foods — are fully developed by the teens year.
　　In fact, these regions are even more sensitive when we are young. That is because dopamine (多巴胺), a natural chemical that lifts our mood when we experience something good , is especially active in adolescent brains.
　　Therefore, the teen brain has two strikes against it when it comes to resisting junk food. "It has a heightened (增强的) drive for rewards and reduced self-regulation (自我调节)." Said Reichelt.
　　So what's the best way to say no to junk foods? Researchers propose to exercise. When we exercise, the brain's reward system becomes less sensitive to food cues (线索). Exercise also triggers (触发) the body to make a protein that helps brain cells grow and boosts connections between the prefrontal cortex and other brain regions. The prefrontal cortex thus can work better to help us make wise decisions and control our impulses.

18．Restorers piece together Terracotta Warriors
　　Lan Desheng, The 52-year-old conservator-restorer (修复者) is part of specialist team pieces together and repairing the Terracotta Army.
　　Pointing to life-size, Terracotta Warriors, Lan said "These are pieces of history that have been vividly preserved (保存). More than 2000 years have slipped by, and you can still sense the huge amount of talent that went into making these figures (塑像)."
　　Lan said the team aims to restore the relics' (遗物) original appearance by applying the principle of minimum intervention (最小干预). On-site, "first aid" is a key element of the work. Using his experience, Lan can tell precisely whether the Terracotta Warriors were made by craftsmen from the Qin Court or by local artisans, as their work is quite different.
　　During the past 25 years, as a researcher with the Emperor Qinshihuang's Mausoleum Site Museum. Lan has restored more than 150 of the figures. He said he was anxious when his first started work in this field. Even though it was his ideal job In 1993 Lan graduate from Northwest University in Xi'an with a major in cultural heritage (文化遗产) and three years later he started work on restoring Terracotta. Warriors.
　　The conservator-restorers face a strict training program . In the first two years. Lan was not allowed to touch the relics. And was told to "observe , remember and read" His first task after his training ended was a locate fragments (碎片) and search for missing parts of the figures among the piled remains. Sometimes he was unable to find a single missing piece and often asked his teacher when he could start to repair a complete Terracotta Warrior.
　　The technology used to restore the figures has changed over the years. But the basic methods remain the same. After fragments of the warriors and horses are collected. The restorers attempt (尝试) to piece them together before using glue to bind them. Over the years , the restorers have become used to delays and the fact that hardly anything can be done immediately. Patience is necessary.
