CaliforniaCondor's Shocking Recovery

      California condors are North America's largest birds, with wing-length of up to 3 meters. In the 1980s, electrical lines and lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.

      In the late 1980s, the last few condors were taken from the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.

Electrical lines have been killing them off. “As they go in to rest for the night, they just don't see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(电死) if they touch two lines at once.

So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%.

Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(肾) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011.

Rideout's team thinks that the California condors' average survival time in the wild is now just under eight years. “Although these measures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them.”

    Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way. You can call a friend using your jacket sleeve. Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example. What will be the next?

    To a growing number of US students in China, study in the ancient country is no longer just a cultural experience it has become an important part of their future professional careers.

    Sam Gor, a 26-year-old student from Santa Clara, a county near San Francisco, said the purpose of his studies in Beijing was to help him find a good job when he goes back to the United States. "Culture matters," he said. "But more importantly, to learn Chinese and get a better understanding of the country may help me professionally." As a new student at Beijing Language and Culture University (BLCU), Gor hopes to find a job in Santa Clara's local government when he goes back home in one year. "I need to learn Chinese if I want the job, as we have a large Chinese community there."

    Gor is not alone in his thinking. While the number of US students in China has grown from less than 100 in the early 1980s to more than 10,000 for the time being. Many of them are here to boost(提高) a professional skill as much as to enjoy a new culture.

    “In the past, foreign students came to China simply for our culture,” said Xu Quihan, director of BLCU's foreign students' office. “But because of China's rapid economic and social development, being able to speak Chinese has become a useful tool to a student's future job”

    There are more US students who choose to stay in the country instead of going back after graduation. Stephanie Schubmehlo, a 23-year-old from Rochester, New York State, said she would like to stay in Beijing after graduation. “I love the city, and I can earn myself a living here if I can speak good Chinese,” she said, adding that some of the US students she knows shared the same idea.

    Sometimes the toughest thing about feelings is sharing them with others．Sharing your feelings helps you whether your feelings are wonderful or terrible．Sharing also helps you to get closer to people you care about and who care about you．But how?

    You can't tell your friends what's inside your backpack if you don't know what's in there yourself．Feelings are the same way．Before you can share them with anyone，you have to figure out what feelings you have．

    Making a list of your feelings can help．You can do this in your mind or by writing it out or even by drawing pictures．Is something bothering you? Does it make you frustrated or terrified? Do you feel this emotion only once in a while or much of the time?

    The way a person feels inside is important．If you keep feelings locked inside，it can even make you feel sick! But if you talk with someone who cares for you，you will almost always start to feel better．It doesn't mean your problems and worries magically disappear，but at least someone else knows what's bothering you and can help you find solutions．

    Your mom and dad want to know if you have problems and what's happening in your life．But what if a kid doesn't want to talk with parents? Then find another trusted adult，like a relative or a teacher at school．Maybe this person can help you talk with your parents about your problem or concern．

    Once you know who you can talk with，you'll want to pick a time and place to talk．You can talk publicly in your family．But some kids are more private than others and they will feel shy about sharing their feelings．Then find a quiet place or write it down on a piece of paper．A kid doesn't have to share every feeling he or she has．

    About 15 years ago, I taught A Problem from Hell, a book on genocides (大屠杀), to a group of 18- and 19-year-olds in a mid-west university in the US. In my class there was a young man who had spent his boyhood in Bosnia as NATO bombed his hometown. My other students, amazed by his connection to the genocide in the textbook, asked him what it was like to grow up in a war-zone. "A pretty normal childhood as you had here," he said. "We played cards inside a lot, and when there was no bombing we kicked a ball in the street."

    In the past few years, the world has seen a rapid increase in refugees (难民), with the number hitting 60 million. Viet Thanh Nguyen's story collection The Refugees reminds us that literature is news that stays news. Set in the Vietnamese communities in California as well as in Vietnam, the stories do not aim to surprise us with new twists or shock us with wonderful details, as war and refugee stories could easily choose to do. Rather, like the young man from Bosnia, Nguyen's characters tell these stories because they are the only ones known to them.

    Included in the collection are two of the most touching pieces, both about siblings (兄弟或姊妹) separated by geography and history. In "Black-Eyed Women", the narrator (讲述人), a young Vietnamese woman, is visited by the ghost of her elder brother, who died young on the boat when the family took flight from the war. The tale of love and loss, violence and violation, may not be unfamiliar to the reader, but the determination of the brother's ghost (he has taken decades to swim across the Pacific to reach America) and the sister's abandoning herself to a half death make the story lasting.

    As an echo, the closing story, "Fatherland", explores a more complex situation between two siblings. The narrator, a young Vietnamese woman, meets her half-sister, visiting from the US for the first time. Adding to the tension is the fact that her father has named the narrator and her siblings after his first set of children. Two sisters, one American and one Vietnamese, yet named the same by the father – it may sound strange, but isn't it the fate many refugees have to face: a life left behind, that could have been theirs; and a life in an adopted country.

    The theme of doubleness –  choice and inevitability (不可避免性), home and homelessness, starting afresh and being stuck – is present not only in the stories of Vietnamese refugees, but also of those who have become refugees from their own homes and loved ones. "Smiling at your relatives never got you very far, but smiling at strangers and acquaintances sometimes did." So a pilot, who fought in the Vietnam war and is now revisiting the country for the first time, thinks while waving at the locals from a tour bus. He's distant from his daughter, just as a Mexican American in the collection is distant from his wife, or a young man from Hong Kong is distant from his father.

    The collection is full of refugees, whether from external or from a deeper, more internal conflict between even those who are closest to each other. With anger but not despair, with reconciliation (和解) but not unrealistic hope, and with genuine humour that is not used to insult anyone, Nguyen has breathed life into many unforgettable characters.

    Everything has a name. All people, places and things have names. For example, Jenny is the name of a student from England. England is the name of her country. Cities and towns have names, too. Schools and office building also have names. All things have names. Names are important.

    Names are different all over the world. In Jenny's class, Jenny must learn the names of students from all over the world. This is very difficult because the names are different.

    In the USA, most people have a first name, a middle name, and a last name. Parents choose the first and middle names for their baby. There are names for boys and names for girls. For example, John, Peter, Tom and Mike are all names for boys. Elizabeth, Betty, Susan, and Mary are all names for girls. The last name is the family name. Usually it is the father's family name. In a family, the mother, the father, and the children usually have the same last name.

    Names are different all over the world. They can be long or short, but they are always very important.
