The new two-child policy is making job hunting more difficult for women when about 40 percent of them said they were asked whether they planned to have a second child during job interviews, according to a report in Chongqing.

    China dropped its decades-long one-child policy in October and allowed each family to have two children. The country now has about 270 million married women of childbearing age.

    This change has put millions of career women in a dilemma between family and career. Employers also face big challenges as more female workers will have two childbearing leaves, seven to eight months altogether.

    A human resources website www.job.cq.qq.com conducted a survey among 500 employers and 5,000 job seekers about how the two-child policy affects the job market.

    Though two thirds of employers said the policy would make no difference to their recruitment(招聘), the survey showed that more than 70 percent of job seekers believe that bearing a second child will make women less popular in the job market. Forty percent of employers said they will give priority to married women with two children, according to the survey.

    Lin Xia, 29, quit her job after giving birth to her first child. She is now preparing to return to work. After several inquiries at a job fair, she found that the employers are concerned about future birth plans. "I thought it would be easier to find a job after giving birth," she was quoted as saying by the website. "I had to answer whether I will have a second child before I could get a chance for a job interview."

    Liang Siqi, 23, a college graduate, said although employers did not ask her the child question yet, she will not plan to have two children. "It (having two children) will definitely affect my career and personal life, so I will have only one," she said.

    Zhou Jiansong, who is in charge of human resources at a large private high-tech group in Chongqing, said the company will discuss birth issues with interviewees in order to make a better work plans. "We fully respect a women's right to bear a child or two," he said. "But you don't want them to go on a childbearing leave soon after they join your company." The experts expect more labor dispute cases concerning childbearing leave rights when bearing a second child in future.

    Dolphins (海豚) live in a dark underwater world. It's often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.

    Only other dolphins understand what the sounds mean. Scientists haven't uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins — and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.

    Dolphins often hunt by themselves but still need to stay connected to the group. Since they can't always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they're a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.

    What's amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It's creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother's or group members' whistles.

    When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it.

    Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins' communication.

    It was almost the worst birthday of Abraham Lincoln's life.

    On February 11, 1861 (the day before he turned fifty-two), Lincoln left for Washington to become the nation's sixteenth President. As he left home in Springfield, Illinois, Lincoln handed his son Robert a black oilskin(油布) bag, and told him to keep it carefully. He did not tell Robert what was inside.

    Unknown to his seventeen-year-old son, Lincoln had placed his newly written inaugural speech in the bag. It was to be the most important speech he ever made. And it was his only copy.

When the train arrived in Indianapolis—the first stop on the long journey—Lincoln rode off in a special carriage without his family. Robert walked from the station to the local hotel.

    When Robert arrived at the hotel, he learned that his family's rooms were not ready. So he asked that the bag should be held at the front desk. Then he went off to be with friends.

    On his return, Robert found his father waiting anxiously. Where was the bag? Robert explained that he had checked it at the desk.

An angry Lincoln sped to the hall and leaped over the front desk. He began searching through a huge pile of luggage.

    As puzzled guests looked on, Lincoln dragged from the pile a familiar-looking black bag and opened it, only to find someone else's dirty clothes. It was the wrong bag. Back he went to the pile.

    At last he found the valuable bag and the speech inside. Lincoln handed it to his son and said strictly, “Now you keep it!”

    It was the one and only time, Robert said, that his father had ever lost his temper at him. But with his speech fond and his birthday yet to be celebrated, Abraham Lincoln grew cheerful. As Robert proudly recalled, “Father did not scold(责骂).”

    I was in a terrible mood. Two of my friends had gone to the movies the night before and hadn't invited me. I was in my room thinking of ways to make them sorry when my father came in.

    "Want to go for a ride, today, Beck? It's a beautiful day."

    "No! Leave me alone!" Those were the last words I said to him that morning. My friends called and invited me to go to the mall with them a few hours later. I forgot to be mad at them and when I came home to find a note on the table. My mother put it where I would be sure to see it.

    "Dad has had an accident. Please meet us at Highland Park Hospital".

    When I reached the hospital, my mother came out and told me my father's injuries were extensive. "Your father told the driver to leave him alone and just call 911, thank God! If he had moved Daddy, there's no telling what might have happened. A broken rib（肋骨）might have pierced（穿透）a lung..."

    My mother may have said more, but I didn't hear. I didn't hear anything except those terrible words: Leave me alone. My dad said them to save himself from being hurt more. How much had I hurt him when I hurled those words at him earlier in the day?

    It was several days later that he was finally able to have a conversation. I held his hand gently, afraid of hurting him.

    "Daddy… I am so sorry…"

    "It's okay, sweetheart. I'll be okay. "

    "No," I said, "I mean about what I said to you that day. You know, that morning?"

My father could no more tell a lie than he could fly. He looked at me and said. "Sweetheart, I don't remember anything about that day, not before, during or after the accident. But I remember kissing you goodnight the night before. "He managed a weak smile.

    My English teacher once told me that words have immeasurable power. They can hurt or they can heal. And we all have the power to choose our words. I intend to do that very carefully from now on.

Learn to cure cancer

    A vaccine for cancer is in the works.

    Lauren Landry and Chloe Tomblin are the scientists. They look in freezers(冰柜) for bacteria to use in the research. This research has its limitations—mostly because their lab is in a high school.

    But Lauren, 16, and Chloe,17 both students are Western Reserve Academy in the US, aren't put off by the difficulties they face in their cancer immunology(免疫学) class.

    “I hope we get to the point where we can get to a vaccine and write a paper,” Lauren said.

    Both conduct research into how to engage the immune system in stopping cancer from forming.

    Though the lab is in a high school, they don't use textbooks. The aim is to conduct real cancer research, either by testing the effects of substances on cancer cells or developing vaccines to target the growth of those harmful cells.

    The idea for the class came from Robert Aguilar, who has taught at the private school for many years. Students spend the first year learning research techniques. In the second year, students swap(调换) their blue lab coats for white ones. By this stage they are well into their research projects.

    “If first-years need any help, they can feel free to ask second-year students,” Aguilar said.

    Students form groups to conduct their research. One pair of students has researched the effect of capsaicin(辣椒素) on killing cancer cells. Another has tested the effect of caffeine(咖啡因) on the growth rate of breast cancer(乳腺癌) cells.

But few students get to the point in their research of experimentation with mice, Aguilar said. Lauren and Chloe hope that they can make decent progress in their work.

    “We know they're going to be used for good,” Lauren said. “If it does or doesn't work, it still has a huge impact.”

    Aguilar teaches the students that even research that doesn't work still contributes to science in some way. He tells students that “the best part of research is failing a lot”.

    I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals for two elderly women in my community. Both had died "full of years", as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.

    At the first home, the son of the deceased(过世的)woman said to me, "If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died." At the second home, the son of the other deceased woman said, "If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It's my fault that she's dead."

    You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course—keeping Mother at home, putting off the operation—would have turned out better. After all, how could it have turned out any worse?

    There seem to be two elements involved in our willingness to feel guilty. The first is our need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens. That leads us to find patterns and connections both where they really exist and where they exist only in our minds.

    The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault. The roots of this feeling may lie in our childhood.

    A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to his tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.
