    “Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American's exports soon after it went on the air in New York in 1969.

    In the United States more than six million children watch the program regularly. The viewers include more than half the nation's pre-school children, from every kind of economic, racial, and geographical group.

    Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.

    Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional（偶然的）viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.

    The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.

    Why has “Sesame Street” been so much more successful than other children's shows? Many reasons have been suggested. People mention the educational theories（理论）of its creators, the support by the government and private（私人的）businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.

    However exciting space exploration sounds, there's a necessary and important point about it that needs to be considered: food supplies. Right now, astronauts typically rely on dry food in airtight bags and cans, since there are strict weight limits on items taken into space. Foods that we take for granted, such as fresh fruits and vegetables, are out of the question for space explorers.

    For those who've made an effort to try to grow food during space flights, they've faced many difficulties, including the absence of gravity, and a lack of soil, air and humidity (湿度). However, growing food to add and minimize (最小化) the food that must be carried to space will be increasingly important on long-duration flights into space. Great efforts have been made to explore the concept (idea) of space farming. Recently, a team led by Federico Maggi at the University of Sydney in Australia have worked out how plants can absorb nutrients from human urine (尿), as was reported by New Scientist on March 27.

    After over 20 years of experiments, the results suggested that human urine could supply three to four out of the six nutrients that plants need. The researchers also found out that urine-fertilized plants produce no harmful by-products, such as carbon dioxide or ammonia.

    According to New Scientist, human urine is 95 percent water, with the other 5 percent made from nutrients which are harmful to the human body but not to plants. The advantage of this urine-fueled life support system is obvious: By recycling liquid waste and producing food, an efficient cycle will be created.

    And most importantly, said New Scientist，the duration of space flights will be greatly extended to “20 years of flight”, meaning we may be soon sending astronauts on flights to Mars, or even beyond.

    As the weekend approaches, perhaps you're looking forward to a meal out or sitting in front of the TV with a takeaway. But as you settle down to enjoy that comforting plate of beef or start spooning that fragrant lamb curry over the rice, will you be worrying about whether you are really eating what was written on the menu?

    Yesterday it was revealed by the Food Standards Agency that more than a fifth of the 665 meat samples tested last year contained DNA from animals not listed on the label. Of the 145 problem samples, 73 came from supermarkets, while 22 came from processing plants. The remaining 50 all came from restaurants.

    I have no doubt that over the next few years, the percentage of meal coming from dubious origins will continue to rise unless something drastic is done. Why? There are two main reasons. First, too many businesses are willing to boost their profits by adulterating their products in the meat industry. I believe there is a systemic problem within the meat industry that makes it particularly attractive to unscrupulous characters who are really nothing more than criminals，the second is the complexity and length of the meat supply chain. If you buy a chicken-based ready meal from a supermarket, as you might imagine, that chicken will pass through many hands before it ends up on your plate here. Worse still, the meat will often he partially processed somewhere along that chain—usually with salt and water added to boost flavour and volume—which is quite legal.

    Obviously, it is impossible for consumers to be detectives about every piece of meal they eat.

    However, what you can do is to avoid processed foods and never buy ready meals. Stay away from burgers made in factories. Don't go to chain restaurants. Instead, go to local, independent restaurants where it is more likely the chef and owner—often the same person—cares about where the meat comes from, and will be happy to tell you. So, try to buy your meat from a good local butcher.

    And no, what I am suggesting is not going to hurt your purse or wallet. The essence, then, is to buy meat that has had as small a journey from field to fork as possible, because that is the only way you can he sure of what you eat. It's that simple.

    After photographer Monni Must's daughter Miya died, the sad mother adopted her black dog, Billy Bean. As Billy became increasingly weak, the thought of its dying was just more than Must could handle. So she decided to clone the dog. “I feared everyone was going to forget Miya," she said, "and my other daughters thought I had completely lost my mind."

    Billy's cells were shipped to ViaGen Pets, a Texas company that provides the cloning service. With more than $50,000, Must picked up a new puppy. "The dog has a real soul and is everything my daughter was—fun, social and kind," she said. "I feel that I still have that touchable connection and not just a spiritual connection.”

    Cloning animals is hardly new. But the recent news that singer Barbra Streisand had cloned her dog grabbed international headlines. People for the Ethical Treatment of Animals(PETA) president Ingrid Newkirk issued a statement saying she would love to talk her out of cloning, noting that millions of wonderful dogs are getting old in animal shelters every year or dying in terrifying ways when abandoned.

    Normally, a doctor takes a tissue biopsy(组织活检), a piece of skin and muscle about the size of a pencil eraser, from the dog. The next step is to take an egg cell from a donor dog, remove the egg's nucleus, and insert DNA from the pet to be cloned. When an embryo(胚胎)develops, it is transplanted in the body of a mother dog.

    In the basic cloning procedure, scientists take an entire adult cell and put it into an egg that's been relieved of its own DNA. The resulting embryo is a clone. However, in many animals, only one in 100 cloned embryos ever leads to a live birth. Some embryos die in the IVF dish or in the mothers bodies. Of those that are born, a few suffer from abnormalities and quickly die. Besides, pet cloning doesn't mean copying everything of your beloved pets.
