1 . In September, a tragedy happened on the west coast of Tasmania, Australia. As many as 380 pilot whales became stranded (搁浅) in shallow water there and later died. This might have been Australia’s largest stranding event on record, the BBC reported.
But mass whale stranding is not uncommon. For centuries, it has happened all over the world and has puzzled scientists. Scientists say the cause is often unknown. But they have offered many different explanations.
Some say the whales chase small fish for food and end up in shallow water because they are not paying attention to where they are going.
Others think the stranding has something to do with Earth’s geomagnetic field. They say that a geomagnetic compass in whales’ brains controls their position. Unusual changes in Earth’s magnetic field can affect the whales’ compasses and send them in the wrong direction.
Another explanation suggests that mass stranding is caused by the close relationships that whales have. Pilot whales travel in large groups. One lead whale might mistakenly lead the whole group to shallow water. “And if one gets into trouble, the others will not leave,” said Sheryl Gibney, a leading biologist from New Zealand. “Some will come in and try to help, they get trapped on the beach, then more will come.”
The whales are trapped by mistake or out of sympathy. Once they get stranded, they will likely die. According to the National Oceanic and Atmospheric Administration of the US, less than 10 percent of all stranded whales survive.

4 . When the leaves begin to change their colors and the birds head south, we know the season is starting to change. On September 7 comes White Dew (白露), the 15th solar term (节气) of the year. It indicates (标志着) the beginning of the cool autumn. As the temperature falls, white dew is often seen on the grass and trees at night.
For w riters and poets, autumn is a difficult season to describe. It ’s the end of the summer, and therefore a little sad. The days seem to get shorter, and when you wake in the morning, t here’s mist(薄雾) and it’s cooler. Winter is just around the corner.
American writer Ernest Hemingway wrote in his book A Moveable Feast (《流动的盛宴》), “You expected to be sad in the fall. Part of you died each year when the leaves fell from the trees and their branches (枝条) were bare (光秃秃的) against the wind and the cold, wintry light. ”
But on the other hand, autumn has its good side. There are so many changes at this time of year, such as the colorful leaves and cooler nights. French w riter Albert Camus even thought autumn was a second spring, “when every leaf is a flower.” This view is also found in the most famous autumn poem in English literature, To Autumn by John Keats. In that poem, Keats says that autumn has its own songs, just like spring.
Another theme of this season is wisdom (智慧). The arrival of autumn is thought to be similar to a person becoming mature (成熟的).
The great Irish poet W.B. Yeats used this idea in his poem The Wild Swans at Coole (《库尔的野 天鹅》), writing about the changing seasons in Coole Park in the west of Ireland. Seeing and counting 59 swans, he remembers first making the count as a young man. Seeing the swans do the same thing for all those years, he’s reminded (提醒) that even though we get older, our hearts always stay the same age.

C.It is when the temperature begins to drop. | D.It indicates the end of the autumn. |
A.point out that autumn is very cold | B.present the sad part of autumn |
C.show that winter w ill soon come | D.express sadness about the end of life |

7 . Though plastic shopping bags are cheap and useful, they cause widespread pollution. Now, we may have an unlikely helper to help clean up our garbage — a small wax worm.
The worm’s hidden skills were discovered by accident. About two years ago, Federica Bertocchini, a developmental biologist at the Spanish National Research Council and an amateur beekeeper, was cleaning out bees’ nest that had been filled with worms. She removed the worms and put them in a plastic bag while doing the cleaning. After finishing, she went back to the room where she had left the worms, and found they had escaped from the bag. When she checked, she saw that the bag was full of holes.
Realizing she may have made an important discovery, Bertocchini teamed up with other researchers to conduct further research. They began by placing 100 worms on some plastic bags and discovered that over a 24-hour period, the worms managed to chew through 92 milligrams of plastic. The researchers make an appropriate judgment that at this rate, the group of worms could degrade (降解) an average-sized 5.5-gram plastic bag within a month. To rule out the possibility that chewing was causing the degradation, the researchers spread the soft wet substance inside the body of some recently dead worms on a sheet of plastic. Sure enough, even the liquid was able to eat through the material, confirming that the worms have plastic-digesting enzymes (酶).
While the news is certainly encouraging, not everyone is convinced. The Michigan State University’s Ramani Narayan believes the tiny pieces of microplastics released by the plastic-eating worms would pick up harmful substances and transport them up the food chain, causing, even more, harm to the environment and human health. Susan Selke, director of Michigan State University School of Packaging, is concerned that the worms will not be able to survive in an oxygen-free landfills where large amounts of waste material are buried under the earth.
However, Bertocchini is not planning to transport worm armies to landfills. Instead, the researcher wants to identify the enzyme that helps degrade the plastic. The researcher says, maybe we can find the molecule (分子) and produce it on an industrial level, rather than using a million worms in a plastic bag.

“I'm going to miss you so much, Poppy, "said the tall, thin teenager. He bent down to hug his old friend goodbye. He stood up, hugged his parents, and smiled, trying not to let his emotions(情绪)get the better of him.
His parents were not quite able to keep theirs under control. They had driven their son several hours out of town to the university where he would soon be living and studying. It was time to say goodbye for now at least. The family hugged and smiled through misty eyes and then laughed.
The boy lifted the last bag onto his shoulder, and flashed a bright smile.” I guess this is it, “he said.” I'll see you back home in a month, okay?"His parents nodded, and they watched as he walked out of sight into the crowds of hundreds of students and parents. The boy's mother turned to the dog, “Okay, Poppy, time to go back home.”
The house seemed quiet as a tomb without the boy living there. All that week, Poppy didn't seem interested in her dinner, her favorite toy, or even in her daily walk. Her owners were sad too, but they knew their son would be back to visit. Poppy didn't.
They offered the dog some of her favorite peanut butter treats. They even let her sit on the sofa, but the old girl just wasn't her usual cheerful self. Her owners started to get worried. "What should we do to cheer Poppy up?"asked Dad. “We've tried everything.”
“I have an idea, but it might be a little crazy, “smiled Mom.” Without anybody left in the house but us, this place could use a bit of fun. Let's get a little dog for Poppy."
It didn't take long before they walked through the front door carrying a big box. Poppy welcomed them home as usual, but when she saw the box, she stopped. She put her nose on it. Her tail began wagging(摆动)ever so slowly, then faster as she caught the smell.

10 . Have you ever wondered what wild animals do when no one is watching? Scientists have been able to record the “private” moments of wildlife with leading-edge technology. Low-cost, dependable and small modern cameras are of big help.
Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to later snow loving felines (猫科) in the northern Rocky Mountains. These cameras are important tools to learn new information on wildlife.
Some videos help scientists see the effects of climate change. For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home. This could mean global warming is enlarging their living area northward.
Researchers use cameras along with global positioning systems, or GPS. They attach GPS devices (设备) to mule deer and antelope in and around Yellowstone National Park. Then they can record their movements, or migrations (迁移) . These cameras can be left in very rural (荒野的) areas for days, weeks or even month. They can provide information on how many animals are moving over a given period of time.
Rural video can show details about animal behavior, such as the calls made by migrating. Also some cameras record animal life and show everything from bison in Saskatchewan, Canada, to the underwater weed forest off California’s Channel Islands.
However, rural cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, rural cameras are clearly an important scientific tool in researching wild animals.
