I was ready to pay for my bananas at the grocery one night, when fear seized me. My wallet was gone. I could only have left it on the G9 bus,which was now speeding in the dark to some _16_ station.
The _17_ moment was quickly followed by mental math. How much time and money would it cost to replace the _18_ of that little wallet? The credit cards, the driver's license, the cash, all lost to the bus.
Two hours later, back at my house, I heard a knock on the door. My husband _19_ it while I was on the phone in the dining room. "Does jennifer live here?" I heard a lady say. In my husband's hand was my wallet, with not a penny _20_ . She left before I could _21_ make it to the door to offer my thanks.
After sharing the story online, I heard from someone, who _22_ the lady as Erin Smith. Without _23_ , I called to thank her. She said she _24_ my wallet on a bus seat. She _25_ that going to a stranger's house was a _26_ move, but she decided to take the chance. "If I were in that _27_ , I would want someone to try to find me", she said.
This one stranger responded beautifully to my small _28_ , but she actually wasn't the only one. Right after Erin _29_ my wallet on the bus, she posted a picture of my driver's license to an online forum（论坛）, trying to see _30_ anyone knew me. No sooner did she leave my doorstep than I had emails from two women whose kids go to my son's nursery and who recognized my face. I've never _31_ words with those moms beyond small talk, but they wanted to help. I read that people are more divided than ever, but that's not how the people I _32_ tend to act.
_33_ , I feel blessed someone had wanted to help a stranger. Erin had gone _34_ what almost anyone would have done, finding my house on a bitterly cold night, and for that I was extremely _35_ .
Understanding history is vital to understanding ourselves as a people and as a nation. History is much more than the study of dusty old objects and events long past. It is an essential part of who we are today and who we will become. Thornton Middle School History Fail Competition makes understanding history exciting, engaging, and fun!
This Year's Theme
All participants must address how communication or transportation technology has promoted the quality of life for Americans throughout history. To many people, technology means computers, hand-held devices, or vehicles that travel to distant planets. However, technology is also the application of scientific knowledge to solve a problem, touching lives in countless ways.

I must have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don't remember mom reading me a storybook by my bedside. I was extremely inspired by the elegant way the words sounded.
I always wanted to know what my mom was reading. Hearing mom say , "I can't believe what's printed in the newspaper this morning," made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.
This is how everyone learned to read. We would start off with sentences , then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, "The C-A-N-D-Y is hidden on the top shelf," I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.
Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A's on my tests. Occasionally, I would read a novel that was assigned, but I didn't enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract left too much room for argument.
Yet, now that I'm growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don't have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.
We're taught to read because it's necessary for much of human understanding. Reading is a vital part of my life. Reading satisfies my desire to keep learning. And I've found that the possibilities that lie with in books are limitless.
How does an ecosystem (生态系统) work? What makes the populations of different species the way they are? Why are there so many flies and so few wolves? To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how mucheach one eats.
With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator ( 掠食动物 ) alway seats huge numbers of a single prey ( 猎物 ), the two species are strongly linked; when a predator lives on various species , they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction ( 灭绝 ) of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover, The weak links may thus keep species from driving one another to extinction.
Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s，scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species- including species they did notdirectly attack.
And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land，wekilled off large predators such as wolves. These actions have greatly affected the ecological balance.
Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists say, because once ecosystems pass their tipping point(临界点), it is remarrkably difficult for them to return.
Would you BET on the future of this man? He is 53 years old. Most of his adult life has been a losing struggle against debt and misfortune. A war injury has made his left hand stop functioning,and he has often been in prison. Driven by heaven-knows-what motives, he determines to write a book.
The book turns out to be one that has appealed to the world for more than 350 years. That former prisoner was Cervantes, and the book was Don Quixote (《堂吉诃德》). And the story poses an interesting question: why do some people discover new vitality and creativity to the end of their days , while others go to seed long before?
We've all known people who run out of steam before they reach life's halfway mark, l'm not talking about those who fail to get to the top. We can't all get there, l'm talking about people who have stopped learning on growing because they have adopted the fixed attitudes and opinions that all too often come with passing years.
Most of us, in fact, progressively narrow the variety of our lives. We succeed in our field of specialization and then become trapped in it. Nothing surprises us. We lose our sense of wonder. But, if we are willing to learn, the opportunities are everywhere.
The things we learn in maturity seldom involve information and skills. We learn to bear with the things we cant change. We learn to avoid self-pity. We learn that however much we try to please, some people are never going to love us—an idea that troubles at first but is eventually relaxing.
With high motivation and enthusiasm, we can keep on learning. Then we will know how important it is to have meaning in our life. However, we can achieve meaning only if we have made a commitment to something larger than our own little egos (自我), whether to loved ones, to fellow humans, to work, or to some moral concept.
Many of us equate (视……等同于) "commitment" with such "caring" occupations as teaching and nursing. But doing any ordinary job as well as one can is in itself an admirable commitment. People who work toward such excellence—whether they are driving a truck, or running a store—make the world better just by being the kind of people they are. They've learned life's most valuable lesson.
