Having friends may well keep you healthier and help you deal with stress better. Some studies show that people with close friends have a greater ability to fight disease than people who are alone.

    Place friendship in the first place. Find the time to be with friends even if it means letting the lawn go unmoved or the dishes unwashed for a while. When you can't get together, use the phone to keep in touch.

    Open up to close friends. Keeping a deep friendship requires a level of “heartfelt” intimacy (亲密). Don't be afraid to express your inner fears and disappointments. Listen to your friends when they have problems, but offer advice only when it's wanted. Help raise friends' self-esteem when they are sad about a job loss, or other such events.

    Have different friends for different activities, such as going to the movies, singing in a choir, and joining in a bowling league.

    Don't wait for a friend to ask for helps. When a friend has the flu, offer to go to the store or drive his or her children to their after-school activities.

    Never take a friendship for granted. Like a good marriage, friendship needs care and patience. Become a joiner. Find a group that matches your interests.

    Talk to strangers. Conversations started in museums, laundry rooms, or bookstores can lead to firm friendship.

    Enroll in an adult-education course. A classroom is an ideal place to meet others with similar interests.

    “A good book might clarify something you knew little about, transform your world view, or move you in ways you didn't think possible. The Soul of an Octopus(章鱼)delivers on all three, ”the magazine New Scientist commented.

    After writing about birds, pigs and tigers, US naturalist Sy Montgomery decided to choose these many-footed animals as the subject of her latest book, The Soul of an Octopus: a surprising exploration into the wonder of consciousness.

    “Here is animal with poisonous liquid like a snake，a beak(喙)like a parrot，and ink like an old-fashioned pen. It can weigh as much as a man and extend as long as a car, yet it can pour its baggy; boneless body through an opening the size of all orange. It can change color and shape. It has a tongue covered with teeth. It can taste with its skin.” Montgomery explained to the National Geographic on why octopuses inspired her.

    What Montgomery is able to show in The Soul of an Octopus is that octopuses are creatures who exhibit personality, intelligence and emotion, despite having nervous systems completely different from our own. She uses different experiments to show that they possess consciousness as well as individual personalities. For example, based on her research, she finds out that Octavia, an octopus caught in the wild, is friendly and good at multi-tasking. And Kali, another octopus，who has been living at the New England Aquarium, is playful and loves exploring.

    Montgomery is a good storyteller. Through her study of, and communication with, these extraordinary creatures she shares what she learns from both science and her experiences. Her skillful writing presents facts together with personal description, which makes the book very informative but easy to read.

    Twenty-five years ago, as a parent educator, I began reading about the dangers of praise. I was completely shocked by what I was learning: praise is not good for our kids. How could that be? So I spent years talking with experts, reading about the effects of praise, and finally decided to close the door on praise and focus on building an encouraging family.

    Even today, with many studies available to parents, I still hear people say, "How can that be? How can saying 'Good job' or 'You're smart' be bad?" I understand. It can be a difficult habit to break.

    If we tell a boy "You are so smart!" when he brings home an A in his math test, how does he feel when he comes home with a D? If we've told him that he is smart, then he will more likely feel a failure when he struggles with homework — "I'm supposed to be smart. Why can't I do this?"

    Praise trains children to depend on constant feedback on what a "great job" they are doing. This dependency shatters rather than builds children's confidence. Praise trains children to ask, "Do you like it?" "Did I do a good job?" "Are you proud of me?" They begin to believe that what others think is more important than what they think about their achievements and mistakes.

    Praise breaks the relationship between parents and children. Without even realizing it, parents may be using praise as a tool to direct the child's behavior. The message is clear — I approve of you when you … and I do not approve of you when you … Living with this kind of constant judgment can damage not only the child's confidence but also the relationship.

    The solution to the problem of praise is encouragement. Encouragement can be given at any time, to anyone, in any situation. It is a comment, an acknowledgment, a statement that focuses on effort, improvement or choice. Hearing "You are so smart!" can leave a child at a loss when they don't do well in a test. Using "That took a lot of work to come home with an A in your test …" gives a child the chance to be something else.

    It is generally acknowledged that young people from poorer socio-economic backgrounds tend to do fess well in the education system. In an attempt to help the children of poor families, a nationwide program called "Headstart" was started in the US in 1965. A lot of money was poured into it. It Look children into pre-school institutions at the age of three and was supposed to help them succeed in school. But the results have been disappointing because the program began too late. Many children who entered it at three were already behind their peers in language and intelligence and the parents were not involved in the process. At the end of each day, "Headstart" children returned to the same disadvantaged home environment.

    To improve the results, another program was started in Missouri that concentrated on parents as the child's first teachers. This program was based on research showing that working with the family is the most effective way of helping children get the best possible start in life. The four-year study included 380 families who were about to have their first child and represented different socio-economic status, age and family structure. The program involved trained educators visiting and working with the parent or parents and the child. The program also gave the parents some guidance, and useful skills on child development.

    At three, the children involved in the "Missouri" program were evaluated with the children selected from the same socio-economic backgrounds and family situations. The results were obvious. The children in the program were more advanced in language development, problem solving and other intellectual skills than their peers. They performed equally well regardless of socio-economic backgrounds or family structure. The one factor that was found to affect the child's development was the poor quality of parent-child interaction. That interaction was not necessarily bad in poorer families.

    The "Missouri" program compares quite distinctly with the "Headstart" program. Without a similar focus of parent education and on the vital importance of the first three years, some evidence indicates that it will not be enough to overcome education unfairness.

    Car washes are a common sight throughout Nigeria, but Madinat Aliyu's roadside business is very special: she is the only woman car-washer in the north of the country.

    "This job has caused me a lot of problems," said the 27-year-old, checking cars waiting to be cleaned in Gusau, the capital of Zamfara state.

    Aliyu took up her work two years ago, hoping to use the 7, 000 naira (£28) she earned every month to put her younger sisters and brothers through school following the death of their mother, the only one who made money to support the family. But her family begged her to stop doing this job, and she has received "judgment and warnings" from strangers too.

    "My grandmother cried for many days. Some people thought it was a joke to bring more customers (顾客). Others said if she is doing it for money, let's just give her money to stop bringing us shame," she said as she got water from a well by the roadside. "But I hate laziness or depending on somebody else."

    However, Aliyu has admirers. "Some customers only allow her to wash their cars," said her colleague (同事) Shamsudeen Mohammed. "I was trained to wash cars by men, and I can honestly tell you women are better to work under," he added.

    Recently another woman came to Aliyu to ask for advice on starting her own car wash. "Unfortunately her family discouraged her. I told her, if you listen to them, you will find yourself begging or marrying a man who is older than your grandfather," she said.

    Though she is considered a pariah (贱民) by many, Aliyu has no plans to stop her work. "I see men doing something and I think I can do it too."
