    One night in March 1999, a man was driving from California to Oregon, US, to visit some friends. He had stopped his car to have some food when he started to hear strange noises. Turning on the headlights, he saw an 8-foot-tall creature covered in thick, dark hair. The creature stared at him for a minute, turned in the road and walked off slowly into the woods.

    In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜马拉雅山地区)and even Hubei Province in China. The creature is known as bigfoot.

    Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(类人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.

    Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet's undiscovered secrets. There is a little evidence(证据)to support the believers' theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.

    But so far, no one has found bones or any other definite proof that the giant creature exists.

    As a result many people believe the evidence is just part of a big trick.

    The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.

    They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.

    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.

    All over the world, children in hospital are being treated with a new kind of medicine：Laughter. Lucy is 23 and works for Theodora Children's Trust. She is one of many clown (小丑) doctors who bring a smile to the faces of sick children.

    “I'm a Theodora clown doctor. I call myself Dr Looloo. I spend two days a week in children's hospitals, making funny faces, telling jokes, and doing magic tricks. As I walk into the wards(病房) I blow bubbles, shake hands with the kids, and make up nonsense songs for those children well enough to sing. I take special balloons to make 'balloon animals' and tell funny stories about them.

    I'm naturally a very cheerful person. I've always been a clown. In fact my father's a clown and I started working with him when I was eight years old. I knew it was just the job for me and I became a clown doctor because I think it's a great way to cheer up sick, frightened children in hospital.

    Being a clown in hospital is very tiring both physically and emotionally. We have to learn not to show our feelings, otherwise we'd be useless. Clown doctors are sensitive but this is not a side most people see. To the children we're happy all the time. I'm still learning to allow myself to feel sad occasionally. There working with a very sick little girl from Bosnia who speaks no English, so our only common language is laughter.

    At weekends I participate in events to raise money for Theodora Children's Trust. It's a charity, so we are paid with the money people give. Being a clown doctor makes the worries of everyday life seem small. All in all I feel honoured to do this job.”

    Africa is a very diverse land with many different tribes. One tradition that many of these groups share is painting or marking their bodies and faces in color. They do this for many reasons. Some marks are used to identify people as part of the group. Other marks are used for ceremonies such as wedding and during times of war. Let's look at some different examples of body painting.

    Red is a common color in body painting because it often represents health and long life. Among the Masai of East Africa, when men are old enough to marry and make decisions for their people, they participate in a special ceremony in which they paint their heads and faces red. This ceremony takes place every seven to fourteen years, so there is not an exact age for participating in it.

    The Samburu, also from East Africa, like to paint their faces and hair red because they think it looks pretty.

    The Masai men also have a unique way of showing that they are brave. To show that he has killed a lion, a man will paint his body with a natural white material, making special marks to represent this accomplishment. The Masai men also use this white to show that they are no longer boys and are considered adults.

    One quite unusual example of face painting is done by the Wodaabe people of West Africa. Once a year, they have a beauty contest for men. The men paint their faces yellow and red. Then they add white and black circles and lines. Black paint is used near the eyes and on the lips to draw attention to the whiteness of their eyes and teeth, which the Wodaabe consider most beautiful. The women then decide which man they like best.

    As you travel, enjoy the beautiful and bright colors of Africa.

    Breakfast is not only the most important meal of the day, but also the most neglected. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.

    Breakfast simply means "break the fast". Your body spends at least 6 to 12 hours each night in a fasting state. In the morning your body needs energy for the day's work ahead.

    A good breakfast should provide up to 1/3 of your total calories needs for the day. On average(平均)we eat 400 less calories for breakfast than for dinner. If breakfast doesn't attract you in the morning, try eating a lighter for the breakfast in the morning.

    If you aren't hungry in the morning, start with something small like juice or toast or have a nutritious mid-morning snack alter when you are hungry.

    So, you say you're on a diet. Some people fear eating breakfast will make them hungrier during the day and they will eat more. It is true that eating breakfast is likely to make you eat more. That's because your body is working all day long, in fact, you are probably not.

    Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state it will not be able to burn those extra calories very quickly. If you feed your body healthy snacks and meals through the day, you are less likely to become hungry and fill yourself as soon as you begin to eat. Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as bread, rice, noodles and cereals(谷物).
