“I wish we hadn't come on this trip!” Jeff's voice echoed across the narrow canyon （峡谷）. His father stopped, breathing heavily. “This is hard on you, but you've got to come through with courage!” He gently placed his hand on the boy's shoulder. “Now, I don't know if I can make it without stopping every so often. You're young, but you're strong and fast. Do you remember the way back from here to the road, if you had to go alone?”

    Jeff flashed back to the painful scene of Mark, his seventeen-year-old brother at their campsite. He was bitten by a snake yesterday. This morning he couldn't move, and the pain got worse. He needed medical attention right away. They had left their phone in the car, and it must have been out of power by then. Leaving Mark at the campsite and seeking help was their only choice.

“Jeff, could you do it?”

    Jeff looked to the end of the canyon, several miles away. He nodded and a plan began to take hold in his mind. “What is the name of that little town we stopped, Dad?” There must be a hospital there.

    “Flint. We parked at the side of the road a few miles out of Flint.”

    Jeff nodded. Then they continued climbing. Stone by stone, they made their way up the canyon. Gradually, Jeff's father grew smaller and smaller in the distance. Jeff waved to him and then climbed toward the road. Two hours later, he finally reached the road and struggled toward the town, almost exhausted.

    “Can't stop.” He thought. “Mark's in big trouble. Keep going.” Suddenly, he saw a truck heading toward him. “Hey, mister!” He shouted, waving both arms. He began to jog toward the truck, and then broke into a full-speed run.

    His chest was burning with every breath when the truck driver stopped by him. Jeff explained breathlessly. The driver reached for his cellphone as soon as he heard about Mark. “Better get the helicopter in there,” he said immediately. But Jeff wasn't sure about that because everything got unclear and then went black and quiet.

    Hours later, Jeff opened his eyes to find his father on a chair nearby. “You're a hero, son,” his father said with a smile. “You had the helicopter sent into the canyon after Mark. I can't tell you how happy I was when I saw it overhead. They got him to the hospital. He's going to be fine soon. I'm so proud of you!”

    Good learners can inspire students or anybody to learn well. Here are some characteristics of good learners.

    Good learners are curious. They wonder about all sorts of things, often about knowledge beyond their areas of expertise(专长){#blank#}1{#/blank#} Finding out about something they didn't know satisfies them for the moment, but their curiosity is addictive.

    Good learners don't give up easily. A few things may come easily to learners but most knowledge arrives after effort{#blank#}2{#/blank#} They try to search out new information. They read, analyze, and evaluate the information they've found. Then they study more and work at what they don't understand.

    Good learners know that a lot of learning isn't fun. The journey to understanding generally isn't all that exciting{#blank#}3{#/blank#} Others need a tiresome attention to detail, and still others need periods of intense mental focus. Your backs hurt, your arms and legs get tired, and your coffee gets cold.

    {#blank#}4{#/blank#} There's always more to know. Good learners are never satisfied with how much they know about anything. They are pulled around by questions—the ones they still can't answer, or the ones without very good answers. Those questions follow them like day follows night with the answers bringing daylight.

    Good learners share what they've learned. Good learners are teachers committed to sharing with others what they've learned{#blank#}5{#/blank#}Good learners can also explain what they know in ways that make sense to others. They are connected to the knowledge passed on to them and committed to leaving what they've learned with others.

A. Good learners stay positive.

B. They write about it, and talk about it.

C. They love the discovery part of learning.

D. Good learners never run out of questions.

E. Some knowledge can broaden our views.

F. Good learners are willing to put in the time.

G. Some learning tasks require boring repetition.

    A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations(语调) of the driver's accent washed over me in a familiar way.

    I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up — the product of his sacrifice.

    And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment, "All that work to get into Harvard, and you study history?"

    Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) — to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative(故事) of upward mobility so your children can do the same.

    I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't huff and get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school!" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.

    Our mother earth is going through a very tough situation and we, the entire human race, are destroying our environment or unconsciously without even realizing its consequences. Now we have to act very smartly and plan something to sustain what we still have, getting all necessary support from nature to lead healthy lives.

    Gardening is always an excellent and environmentally friendly idea. If you can go for sustainable gardening, then it will be even more useful for all. Gardening is a favorite hobby for many. It is time to channelize your hobby towards a more meaningful motivation.

    When we do gardening we need to use different ingredients (材料) to grow plants. Some of them are natural resources like water, soil, sunshine, and many things like this. Using these resources smartly is a part of sustainable gardening. Some simple techniques include: use less water and organic things to grow plants; try to store rainwater so that you can use them for gardening; try using less energy to drive devices; avoid using plastics in any form while gardening; reuse the leaves from your garden to fertilize them. These are the basic sustainable measures. To do so we need to have proper knowledge about gardening and its requirements so that we can use proper resources without wasting any of them.

    In today's busy life we don't get much time to spend on our environment. Gardening gives us a chance to do so. We can also have some pesticide-free (无农药的) and fresh food if we grow them in our garden. This is the right time to do some good to protect our own environment and gardening is one of the easiest ways. Do you want to start gardening, but you're not sure how?
