Jack London, one of America's major writers of adventure tales, was born in California in 1876. During his life, London worked at many jobs. His broad life experiences would become the background for his writing.

    London loved to read. As a teenager, he spent many hours educating himself at the Oakland, California, public library. He attended college at the University of California at Berkeley, but he stayed for only six months. He thought Berkeley was “not lively enough” and wanted to do something more exciting.

    London wrote stories about working people and the hard times they had making a living. He knew their problems first hand. He worked as a sailor, farmer, factory employee, railroad worker, and gold prospector, to name just a few of his many jobs.

    London grew up near the waterfront in Oakland. He loved the water. When he was fifteen years old, he bought a small sailboat called a sloop. Later he sailed to Japan on a schooner, which is a much larger sailing boat. Like many people of the time, London caught the Klondike Gold Rush Fever. In 1897, he headed for Alaska. He didn't find gold, but he discovered something even more valuable. He discovered that people enjoyed listening to the stories he made up with his vivid imagination. London entertained the miners with story after story. Later, using his experiences during the Gold Rush, he created many more colorful stories.

    London resolved to live a full, exciting life. He once said, “I would rather be a superb meteor(流星), every atom of me in magnificent glow, than a sleepy and permanent planet.” Each day, he pushed himself. Once London determined that he was going to be a writer, nothing could stop him. His goal was to write at least one thousand words every day. He refused to stop even when he was sick. In eighteen years, the writer published fifty-one books and hundreds of articles. He was the best-selling and highest-paid author of his day. Many people also considered him to be the best writer. White Fang and The Call of the Wild are his most famous stories and are about surviving in the Alaskan wilderness. Readers can enjoy Jack London's energy and his talent for telling wonderful stories each time they open one of his novels.

    If you could sail around the world with only one companion, who would you choose? Guirec Soudee, a 24-year-old man from France, chose his pet chicken.

    Soudee has been sailing around the world for two years. No matter which country he sails to, Monique, the hen, is by his side. He found her in the Canary Islands and knew right away they were meant to be best companions. "I didn't speak any Spanish and she didn't speak any French, however, we could always have a small talk, even though she didn't understand me." Soudee joked.

    He had always wanted a companion for his journey and originally thought about bringing a cat, before deciding it would be too much work to look after on a boat. Upon meeting Monique, Soudee realized a hen was the perfect choice. He believed they could communicate with each other well.

    Not only does it cost little to raise Monique, but she lays eggs as well — some things that are always a plus in a situation where storing a lot of food can be a challenge. She lays about six eggs a week on average, even in cold climates like Greenland, where Soudee and Monique are docked(进港) now.

    And what happens when the weather at sea gets bad? Usually Soudee lets Monique stay freely on the boat, but when the winds get terrible he ensures she is safe in her hutch so that she doesn't fall out of his boat and into the sea. Another thing Soudee must care for is the rule in every country he visits. They had met with customs officials in Canada. He was permitted to keep her, but he knows they might not always be so lucky.

    Although Monique can sometimes get on his nerves, Soudee says she's much better than a human companion aboard. "She follows me everywhere. All I need to do is shout 'Monique!' and she will come to me, sit on me, listen to my small talk and give me company," he said.

    After visiting Greenland, they'll head down the Bering Strait to Nome, Alaska. From there the destination is undecided, but Soudee will certainly discuss where they should travel to next with Monique.

Scientists have discovered a bit of hand-made string (线绳) that's around 50,000 years old in Neanderthal remains. The first Neanderthal remains were found in the Neander Valley in Germany, which is where the name comes from. Neanderthals may have lived mainly in caves and made stone tools, but recent discoveries have given hints that Neanderthals developed some advanced skills that people used to think impossible. For example, Neanderthals knew how to make glue from the bark (树皮) of a tree.

Now, scientists report they've found a piece of string on a stone tool made by Neanderthals. Before this, the oldest known piece of string was one made by humans about 19,000 years ago. The string is about a quarter of an inch long. Almost all things made from plants during that time have broken down and disappeared, so it's very special to find this bit of string.

The scientists don't know whether the string was attached to the tool. But that doesn't interest them as much as the fact that Neanderthals knew how to make string. Bruce Hardy, the lead scientist on the project, says that knowing how to make string was meaningful for humans. "We wouldn't really be here today without that technology," he says.

Making string is a very arduous process. This string was made from the inside bark of an evergreen tree. To make string that is strong enough, the string must be made of several smaller fibers twisted (缠绕) together in a special way. For the Neanderthal string, several fibers needed to be twisted together into something like yarn. Then three pieces of yam needed to be twisted together in the opposite direction to make the final string.

The scientists aren't sure what the string was used for, but they say that string like. the bit that was found could be used to make bags, baskets, traps, or other things. The researchers also suggest that because Neanderthals needed to make pairs and count fibers to make the string, the bit of string may also tell us something about the kinds of math that Neanderthals could do.

Though new term had begun for weeks, the new girl Molly still remained 1 around her classmates. Now she was sitting at the picnic table alone. She seemed unsure of what to do or say, yet I could see her eyes longing for 2 .

Brianna, the class clown, was standing near the playground making the other students laugh, as usual. "Brianna, Molly looks awfully 3 . Would you invite her to join us?" I said.

Brianna sighed. I could tell that she was 4 to do what I was asking of her, but I also knew she was so sweet and kind. I had specifically 5 her for this task. She looked at her friends, then at Molly.

Knowing this choice was 6 her, I reached into my pocket and pulled out a D-buck, our class currency(货币). I needed to 7 her cooperation.

"Here, I'll 8 you for your time."

She offered an insincere smile, grasped the green paper, and headed off.

I watched closely as the girls talked. When they finally walked back together, I sighed with 9 .

A minute later, Brianna came back and handed me the D-buck.

"I shouldn't keep this." Her eyes fell to her feet, 10 radiating from her quiet voice. "I don't want Molly to think I only went to get her so I could earn a D-buck. She's my friend."

Then Brianna skipped back to amuse her classmates again, and who laughed for the first time that week? Molly.

 "Mommy!"I called over my shoulder. "Grace is here!" Our neighbor, Grace, stood on our front door holding a cardboard box. 

It took Mom a few minutes to get to the front door. At forty-two, her health wasn't good. She smiled at our next-door neighbor. "Come in and have a cup of coffee." "I can't stay, Nancy," Grace answered. "I just thought you all might be able to use some of this food. We get more at those giveaways than we can use." I felt relieved that Grace couldn't stay. She was friendly enough, but she and her husband drank a lot and they were given to loud arguments late at night. Sometimes, the police had to come and break up the fights. I was a little frightened of them. Grace placed the box on the kitchen table. Mom, who was not the sentimental type, got tears in her eyes."Grace! We can't take this."

Dad wandered in from the bedroom where he had been napping. He wasn't dealing very well with the unemployment at the processing plant. "We don't accept charity," he said. "Now, Jim," said Grace, "this is no time for your pride. You have two little girls and a sick wife to think of. This isn't charity. It's one neighbor helping another." I stood a little distance from the grownups, looking into each of their faces, wondering what was going to happen next. "I thank you kindly," Dad said at last.

When she was gone, we examined the contents of the box. It wasn't what we were used to. Mom smiled and said, "This will get us through for a couple of weeks." The gesture from Grace confused me because she wasn't family, or close friends with us. Even though I didn't like most of the food in that box, I knew there was something significant about this woman's generosity. She didn't have much to give, but she gave what she had at a time when our family needed help.
