    How long has 3-D technology been around? Most of us might think of crowds of teenagers in a 1950's movie house watching Bwana Devil in 3-D. But 3-D technology made its first appearance on the scene in 1838 with the first stereoscope(体视镜). And the first actual 3-D movie was a 1903 film called Le Ariveed'un Train.

    Although it has such a long history, the technology has still remained based on one simple principle—to make 3-D effects you must find a way to project two slightly different pictures to each eye. Modern 3-D technology works by rapidly flickering(闪动)two versions of the movie and projecting them onto each eye. The brain does the rest of the work, combining the two pictures together into one and giving the show the appearance of depth, the third dimension.

    But does this exposure, especially long exposures, cause harm to the child's developing brain and visual system? Unfortunately, long-term studies on new flicker digital 3-D technology and children aren't yet available. We do not know if regular or daily 3-D viewing over years affects the developing visual system, although older 3-D methods basically do the same thing and are not considered harmful.

    The question of possible harm in modern 3-D use in TV is really based on two facts: the amount of time children will now be watching 3-D TV each day and the sensitivity some children show in reaction to 3-D viewing. It is difficult to make actual lab studies of longer term 3-D viewing in children because of the possible harm of the experiment. Researchers will have to wait until 3-D TV technology is already in the marketplace for a number of years, then check heavy 3-D TV watchers and compare them with non-watchers.

    With a 3-D television technology in the home, we will soon be able to answer the question of whether or not longer and more frequent periods of 3-D exposure cause more changes in the visual system. We may find that the bigger problem is the introduction of a new technology that leads to even more time spent on TV rather than playing outdoors.

(1)、According to the text, 3-D technology ______

A、was refused by people when it first appeared. B、will soon change the way we watch TV. C、does no good to our visual system. D、has a history of nearly 200 years.
(2)、Paragraph 2 is mainly about________

A、how 3-D technology works. B、why 3-D movies are popular C、the history of 3-D technology. D、the influence of 3-D technology.
(3)、What's the method suggested in paragraph 4?

A、To wait and see B、To carry out lab studies C、To stop making 3-D movies D、To improve 3-D technology
(4)、The author's purpose in writing the text is to _______

A、ask children not to watch 3-D movies B、discuss if 3-D viewing is harmful to children. C、introduce the advantages of 3-D technology. D、predict the development of 3-D technology.

    Meet big brother Blue and his sisters Meadow and Little Willow, a family of three blind cats that got adopted by the family Catherine Magno.

    Their story starts just before the Christmas of 2014 when the kittens (小猫) were found in an abandoned house in Dubai. By then they had already lost their sight due to a cat flu that was left untreated by their previous (先前的) owner. After that they came to an animal home. At some point, brother Blue almost got adopted by the previous owner's neighbor, but the poor confused cat couldn't bear living without his sisters and cried all night while searching for them. Soon they were all united in the animal home until the important night of 19 February 2015, when Catherine took under her wing.

    “I had zero experience having adopted my first ever rescue kitten just a couple of months ago,” Catherine said. “But their story touched my heart so much that I couldn't bear the thought of them being put in a cage for a very long time or even worse.”

    Catherine was worried about the special needs of her new pet friends: “My worry was that it's going to not only be challenging but also require a lot of adjustments on my part,” but apparently it wasn't that much different. “The only adjustment early on was keeping everything where it was but they are soon adaptive(适应的).” And as she wonderfully put it: “Blind pets see through their hearts.”

    Today, we know that the role of vitamins and minerals goes way beyond the prevention of deficiency diseases (维生素缺乏症) to actually preventing cancer and heart disease, the most fearsome killers of our time. With this knowledge has come the widespread call for nutritional supplementation (营养补充) — and a confusing group of vitamin, mineral, and supplements lining the supermarket shelves.

    Far from contributing to better health, however, nutritional supplements threaten to turn a scientific breakthrough into a nutritional disaster.

    Promoters of vitamins and minerals — especially vitamins A, C, and E— would have consumers believe that the little vitamin pill in the bottle is all they need for good health. Take your vitamins in the morning, and you're covered. It's okay to eat fast foods for the rest of the day or skip meals to achieve today's fashionably skinny look. But vitamins and minerals are only one part of the nutritional puzzle. A diet rich in fiber (纤维) and balanced in carbohydrates and protein is essential for good health. You can't get these things from a nutritional supplement. The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek.

    And no supplement can compare to the quality of nutrition found in natural sources. For example, our bodies turn carotenes (胡萝卜素) from plant foods into vitamin A. Many supplements contain a single carotene, but natural sources are rich in many different carotenes. Many supplements contain a form of vitamin E that is made from chemicals, when natural vitamin E is more readily absorbed and used by the body. And science is still discovering the wealth of nutrients in foods.

    You'd be hard-pressed to find a supplement as nutritionally comprehensive and powerful as a balanced diet. Even if you could, you'd pay much more than if you got the same nutritional value from natural sources.

    But perhaps the greatest danger presented by nutritional supplements comes from the very real risks presented by self-medication. Anyone can walk into the market and buy as many different supplements as desired. The reported benefits of high dosages of certain nutrients have led some people to believe that the more the better. Many take several vitamin and mineral supplements without regard to possible consequences.

    Surprising new research suggests that vitamin C pills may speed up hardening of the arteries, the underlying cause of heart attacks. Researchers said their findings support the recommendations of health organizations, which urge people to avoid high doses of supplements and to get their nutrients from food instead.

    As appealing as they're made to sound, nutritional supplements are danger in disguise. If you're looking for good health, don't look on the supplement shelves of your supermarket. Look in the produce section instead.

    Today, I made the time to listen to a person new to me, who I met was parking my car, “Perfect”, he said as he walked by me as I checked how considerately I parked. He was a clean cut gentleman sharing his feelings about his grown kids, parenting mistakes he is aware of, while expressing a realization to slay clear of destructive addictions.

    I listened patiently and kindly. He seemed quite comfortable with me, in need of some treatment letting go of his thoughts and emotions. After talking for a while, I had to go inside, and I asked him to wait on the sidewalk and I'd be right back with some gifts for him. He was so receptive all along, and I could feel the desires of his heart. I returned to him with bookmarks. I encouraged him, also, with a couple of inspirational thoughts to live by: To focus on what you want — how you want to feel and how you want to live and experience life.

    This experience is a good thing to me, meeting this gentleman as I am experiencing the challenges of trying to be a positive encouragement to my daughter Angel in fighting her illness. I know Angel has the desire too, although in a different way and at a different level in her growth.

    I've received little to no reaction from Angel about the positive encouragement of the family. On the other hand, this gentleman paid attention. Some of this, of course, is the big age difference, I imagine. Anyhow, I extended myself in friendship to have a walk and talk with my daughter early tomorrow morning, so as to be a curing support, and it feels good for me, too — although far outside my usual comfort zone.

    The United States will introduce a new and comprehensive(综合的) exam for students who seek to study in American and other English-speaking countries, Xinhua News Agency reported from New York.

    The exam, which stands for a great change from the current English level test, was disclosed by Theresa Chang Wei Jen, associate director of the International Service of the US College Board, America's leading educational organization.

    The Advanced Placement International English Language (APIEL) will be offered for the first time throughout the world on May 10, 2002, said Jen.

    However, the APIEL is a strange title to most Chinese students, and it is unlikely to soon gain the similarity of other already existing exams, such as the TOEFL(Test of English as a Foreign Language), the GRE(Graduate Record Examination), or the IELTS(International English Language Testing System).

    "I have never heard of such a test and I would prefer the IELTS if I need another exam," said Xu Jingyan, a graduating student from Beijing University of Aeronautics and Astronautics, who wants to study in England and has already taken the TOEFL.

    Most of Xu's classmates have never heard of the APIEL. "The APIEL is designed for international students who wish to get university studies in English-speaking countries, including the United States, Britain, Canada, and Australia." said Jen.

    The APIEL has been adopted, said Jen, because the TOEFL can no longer accurately reflect the abilities of students of using the English language comprehensively in an academic environment. Xinhua reported that a fairly large number of foreign students who earned high scores in TOEFL exam turned out to be very ordinary educational performers after admission.

    Compared with the TOEFL, the APIEL measures a student's ability to read, write, speak and understand English through testing his or her skills in listening comprehension, speaking with accuracy(精确) and resourcefulness, and writing with clarity(清晰) and fluency, Jen said.

The Trip to Alishan in Taiwan

    It was the fourth day of our trip to Taiwan, bright but cold. After a good breakfast we put on our jackets and gloves, pulled on our hats and got into a car. We travelled for about two hours, up, and up, and up the mountain road.

    We finally arrived at the top of the mountain. It was Christmas Day. So imagine my joy to see icicles(冰柱)hanging form branches and the whiteness of the scenery. Indeed, it was my first Christmas in the northern hemisphere(半球)and, guess what? It even started snowing too. How amazingly exciting for me to have Christmas in my grandmother's hometown, and to experience icicles and snow. Alishan is really beautiful, especially seen form this dizzy height. After Sun parked the car, we got out and looked down through the trees. It hadn't snowed hard enough so there was no snow on the ground, just loads of pine needles. There was a most wonderful smell of pine sap(松液)drifting up to us form the ground. It was very quiet, except for the twittering of birds, and the odd car passing along the road. Quietness in Taiwan is something to treasure.

    Over the road was a small stall so we went over to it. They were selling some drink steaming hot in paper cups, too hot to hold immediately. We jumped around to get warm. There was a cool wind blowing up the side of the mountain, and the clouds above us were moving along quickly. I could imagine there was quite a strong wind blowing up there, so I was glad we were down on the ground! The drink cooled down fairly rapidly. I picked up my share and, wow, what a lovely smell was coming from it. It was the smell of ginger(姜).I took a sip. How delicious, and so this was ginger tea, which I had never tried before. It warmed my body so quickly that I could feel the heat travel right down to my fingers and to my toes. This was very good stuff. And then it was time to leave as we were going down to Hualian to attend a Buddha bi-bi, eat hot pot, and drink some Shaoxing rice wine.
