The Healthy Habits Survey shows that only about one third of American seniors have correct habits . Here are some findings and expert advice.

    There aren't many actors around the world who have enough self confidence to turn down an offer from Steven Spielberg. Maybe that was why Juliette Binoche gave him a choice. She said she'd be happy to be in Jurassic Park as long as she could play a dinosaur. Of course he turned her down and it was probably a good thing. It's difficult to imagine Juliette ripping people apart with her teeth. However, her decision doesn't seem to have done her career any harm. She has gone on to make a string of hits, including The Unbearable Lightness of Being, The English Patient (for which she won an Oscar) and Chocolat.

    Success in the United States has not been so easy for other foreign stars. Gerald Depardieu is a good example. Since his first film in 1967, his filmography (影片集锦) lists 172 acting credits. But he has struggled on the other side of the pond. While some of his films have been popular in the US, they have usually been French films that travelled. One possible exception was Green Card, directed by Peter Weir, where he plays a French immigrant who goes through a fake wedding in order to stay and work in the United States. This is a predictable but sweet romantic comedy which typecasts (分配同一类型角色) its lead actors in terms of national stereotypes. While some reviewers were kind, others shredded both the film and Depardieu's performance.

    While Monsieur Depardieu hasn't received the recognition he would have liked in the United States, one Mexican actor has achieved almost instant success. Gael Garcia Bernal first gained recognition in Amores Perros in 2000 and a year later in Y tu mama tambien. Since then he has appeared with hometown hero, Brad Pitt in Babel and, under the direction of top producer and director, Jim Jarmusch, he starred in Limits of Control. He hasn't picked up an Oscar yet, but he was nominated for a BAFTA (英国电影电视艺术学院奖) in 2005 for his performance as the South American hero revolutionary Che Guevara, in Motorcycle Diaries. In the same year he played American music icon Elvis Presley in The King.

    Kids and science seem to be made for each other!

    The basic science is a combination of thought and experiment called the scientific method. It's where you start with an idea, create a way to prove or disprove your idea, and show what you learned based on facts. Learning to follow this process helps you think logically (逻辑地) and carefully. These important thinking skills can be used in many areas of study. To give a child practice with these thinking skills is like giving vitamins (维生素) to a developing mind.

    One of the greatest things we can teach our children is to love learning. Learning science is a great way to do so. Children are easy to be interested in science. Because much of science is hands­on, it attracts most children. Nothing makes a child sit up and take notice like the "WOW!" of a great science showing.

    Science opens doors to many subjects at school. Building love for science can be helpful in other areas of study. For example, one cannot love science for very long without becoming good at its language — math! So science encourages children to study math. An interest in science is an interest in how things were once understood compared to how they are understood now. Thus studying science lends itself easily to studying history. And after you do an experiment, you need to write a lab report. Therefore, writing becomes an important part of science.

    Science is the basic thing for much of our life. The science of farming shows how our food is produced; biomedical science keeps us healthy; even our beds these days are designed according to scientific facts. We almost eat, sleep and breathe with the help of science! When we prepare the next generation (一代) of voters, creators, and policy makers, it is important to make sure they are not only comfortable but also good at science.

    One day, Jack's parents told him that his grandpa would retire after working for forty years. Jack said in surprise, "I'm only seven, so it means grandpa has been…er... a really long time!"

    His parents said, "Yes. That's why we are going to have a surprise party for him. "

    Jack loved his grandpa and wanted to do something special for him. He remembered the business card his grandpa had given him two years before. He knew that his grandpa would no longer have the position on that card, so he decided to build a new one for his grandpa.

    When the big day came, Jack was ready. But he didn't want to put his gift together with others'. He carried it around with him the whole evening.

    When all the other people left, he took his grandpa's hand and brought him over to a chair and gave him the gift. His grandpa smiled, "Well, it must be a beautiful gift. May I open it now?" "Sure! "Jack said excitedly.

    As his grandpa opened the gift, tears came into his eyes. Jack gave him the greatest gift he had ever got! They were business cards with his new position FULL-TIME GRANDPA! Jack said, "Now your full-time job is my grandpa!"

    "Well, how much do I get paid?" his grandpa asked, smiling. "As many hugs as you want!" With these words, Jack gave his grandpa a hug. "Well, I guess that means I'm the richest man in the world!" said his grandpa.

The periodic table of elements is a common sight in classrooms，campus hallways and libraries. The mode periodic table arranges the elements by their atomic numbers and periodic properties（周期性）. Several scientists worked over a century to assemble the elements into this format. 

In 1789，French chemist Antoine Lavoisiertried grouping the elements as metals and nonmetals. Forty years later，German physicist Johann Wolfgang Dobereiner observed similarities in physical and chemical properties of certain elements. He arranged them in groups of three in increasing order of atomic weight and called them triads，observing that some properties of the middle element，such as atomic weight and density，approximated the average value of these properties in the other two in each triad. 

A breakthrough came with the pu blication of a revised list of elements and their atomic masses at the first international conference of chemistry in Karlsruhe，Germany，in 1860. They concluded hydrogen would be assigned the atomic weight of 1 and that the atomic weight of other elements would be decided by comparison with hydrogen. For example，carbon，being 12 times heavier than hydrogen，would have an atomic weight of 12. 

In 1869，Russian chemist Dmitri Mendeleev created the framework that became the moder periodic table，leaving gaps for elements that were yet to be discovered. Mendeleev predicted the properties of some undiscovered elements and gave them names such as"eka-aluminum"for an element with properties similar to aluminum. Later "eka-aluminum"was discovered as gallium. 

German chemist Lothar Meyer produced a version of the periodic table similar to Mendeleev's in 1870. He left gaps for undiscovered elements but never predicted their properties. The Royal Society of London awarded the Davy Medal in 1882 to both Mendeleev and Meyer. The later discovery of elements predicted by Mendeleev verified（证实）his predictions and his periodic table won universal recognition. In 1955 the 101st element was named mendelevium in his honor. 

On UNESCO website，it wrote，"The Periodic Table of Chemical Elements is more than just a guide or catalogue of the entire known atoms in the universe；it is essentially a window on the universe，helping to expand our understanding of the world around us. "
