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.

When Lady Gaga releases a new, pleasing and easily remembered single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another creature----the humpback whale. The mammals become absorbed by new tunes just like people do, and the most popular original whale songs spread globally like hit singles.
Male humpback whales are famed for the loud, long and complicated songs they make during the mating season. Each song lasts for 10 to 20 minutes and the males can sing nonstop for 24 hours. At any one time, all the males in a population sing the same song.
But a study shows that this song changes over time and spreads around the oceans. Dr. Ellen Garland of Queensland University, said: “Songs move like cultural communication from one population to another, causing all males to change their song to a new version.”
Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes two years for songs that appear in the waters off Australia to be heard in French Polynesia.
Most of the new songs contain material from the previous year mixed with something new. “ It would be like getting an old Beatles song together with U2,” she said. “ Occasionally they completely throw the current song out of the window and start singing a completely new song”.
Dr. Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales.
The researchers suspect whales adopt new songs to make themselves distinct. Dr. Garland said: “ we think this male search for new songs is in the hope of being that little bit different and perhaps more attractive to the opposite sex.”

As we know, Julian Beever is an international well-known sidewalk chalk artist whose drawings have appeared on the streets of London, Buenos Aires, Paris, New York, and countless other cities around the world. Beever creates drawings that look completely three- dimensional when seen from the correct angle.

Now, in his book, Pavement chalk artist: The three-dimensional drawings of Julian Beever, the artist shares some of his most fascinating and humorous pieces, Here are a few examples you’ll find in the book.
●Philadelphia eagle
In Pennsylvania, Beever created “Philadelphia eagle ”a huge drawing with an eagle landing successfully on an American national flag.

●Meeting Mr. Frog
“Meeting Mr. Frog” was created in Salamanca, Spain, and is about a realistic-looking frog sitting on a Lily pad.

●Swimming pool in the high street
My personal favorite is “Swimming pool in the high street” from Brussels, which is about a woman relaxing in a swimming pool-----a swimming pool sunk into the middle of the street, that is!
Along with an introduction about his background, Beever includes a description of the techniques he used and the challenges he overcame with every drawing. He shares information about his time at home in the UK. and abroad; there is a fun story to back up each piece of art.
Beever’s artwork is truly jaw drooping. You’re sure to spend ages turning the leaves back and forth, surprised at how one man can create what looks like a three-dimensional design on a flat surface with just a bit of chalk. From animals to superheroes to famous buildings, the paintings are a wonder to lay eyes on.

When I was 11, I threw a glance into Dad’s lunch box and made the unexpected discovery that my mother still showed her love towards my father. The evidence, a napkin resting on top of the sandwiches packed in wax paper, was certain “Love you!” she had written on the napkin. “ Meat loaf for supper!”
Mom penned all kinds of messages to Dad on those paper napkins, and he saved a whole pile of them. What embarrassed me as a kid has become a precious memory of my parents.
It also started my own brand of lunch box notes. When my kids were young, I’d glue little drawings on their lunches. Lots of sketches(素描) of our dog, Max, along with smiling flowers. When they were teenagers, I’d copy words of wisdom from great people, Einstein, for example, or Bruce Springsteen. Then, my kids grew up making their own handwritten notes. And my husband writes me love notes on recycled paper, because he’s all about being green.
Friends who know about my lunch box notes eagerly share stories of their own family traditions. So many focus on food. Maura’s mom always drew hearts on the shells of hard-boiled eggs. Melinda wrote messages on her kids’ bananas.
We’re into the third generation of lunch box notes in our home. Whenever my 3-year-old grandson, Clayton, spends the night, he knows his lunch is going to have a napkin note from Grandma in the morning. Last week, I drew a picture of me, waving widely and shouting his name. He took one look at it and screamed, “ Where’s Grandpa?” I added a man in a clean shirt. “ You forgot his tie,” he said. I quickly drew a line of stripes(条纹) down the front of the shirt. Clayton smiled. “Grandpa,” he whispered, running his fingers across the napkin. “ It’s you!”

Downing the last drop of an expensive famous brand H2O as well as remembering to throw the empty bottle in the recycling bin, makes you feel pretty good about yourself, right? It shouldn't. Even when the bottles are recycled，there are all kinds of other consequences of swallowing bottled water，says Melissa Peffers，the air-quality program manager for Environmental Defense.
The containers are often filled in faraway lands，then shipped from abroad，and stored in refrigerators at your local store. Compare that with the influence on environment of turning on your tap，filling a glass，and drinking up！
Anyone who is choosing bottled water for health reasons is misguided，says Peffers，“Most bottled water is just tap water.”And what comes out of your tap is carefully monitored to follow the strict rules. Consider another fact that bottled water is surprisingly expensive, especially when compared with the alternative, which is almost free, and it is astonishing that America's desire for bottled water seems impossible to satisfy, reaching nearly 30 billion bottles a year.
“My parents' generation never had bottled water，”says Isabelle Silverman，an Environmental Defense legal adviser. She has made a commitment to going bottle free.“You don't need to fetch it home from the store，and it's cheaper，” she adds.
Bottled water's role as a status symbol needs to change, Peffers points out. So when a waiter at an expensive restaurant offers“And what's your drink?”that's no reason to forget your conviction(信念).“Don't be afraid to say, ‘I'll have tap.’ Say it loud enough that the other tables nearby can hear you，”Peffers says,“And then spend that money on a dessert.”
In the first paragraph, the underlined sentence “It shouldn’t.”suggests that people_____

A．shouldn’t feel pleased with finishing the water in the bottle

B．shouldn’t feel good about drinking an expensive brand H2O

C．shouldn’t be content with just recycling empty bottles

D．shouldn’t be satisfied with drinking only bottle water

According to the author，tap water is________

A．as safe as bottle water

B．more likely to be polluted

C．healthier than bottle water

D．less convenient than bottle water

The underlined part “going bottle free”(in Para.4)means “________”

A．making bottled water free

B．abandoning bottled water

C．recycling used water bottles

D．providing free water containers

Why does Peffers ask people to say “I’ll have tap.”loudly?

A．To encourage them to set an example for others to follow

B．To advise them to save the money for one more dessert

C．To remind them to be aware of their social status

D．To persuade them to speak confidently in public
