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.

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.

 

Rome had the Forum (论坛). London has Speaker’s Corner. Now always-on-the-go New Yorkers have Liz and Bill.

Liz and Bill, two college graduates in their early 20s, have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street comers. And just talk. Using a 2-foot-tall sign that says, “ Talk to Me,” they attract conversationalists, who one evening included a mental patient, and men in business suits.

They don’t collect money. They don’t push religion (宗教). So what’s the point?

“To see what happens,” said Liz. “ We simply enjoy life with open talk.”

Shortly after the September 11, 2001 attacks, they decided to walk from New York City to Washington, a 270-mile trip. They found they loved talking to people along the way and wanted to continue talking with strangers after their return. “ It started as a crazy idea.” Liz said. “ We were so curious about all the 10 strangers walking by with their life stories. People will talk to us about anything: their job, their clothes, their childhood experiences, anything.” Denise wanted to talk about an exam she was about to take. She had stopped by for the second time in two days, to let the two listeners know how it went. Marcia had led her husband to a serious disease. “That was very heavy on my mind.” Marcia said. “ To be able to talk about it to total strangers was very good,” she explained.

To celebrate a year of talking, the two held a get-together in a city park for all the people they had met over the past year. A few hundred people appeared, as well as some television cameramen and reporters. They may plan more parties or try to attract more people to join their informal talks. Some publishers have expressed interest in a book, something the two say they’ll consider before making a decision.

1.What did Liz and Bill determined to do after the attack on September 11, 2001?

A. Telling stories to strangers.

B. Setting up street signs.

C. Talking with people

D. Organizing a speaker’s party.

2.Why are Denise and Marcia mentioned in the text?

A. They knew Liz and Bill very well.

B. They happened to meet the writer of the text.

C. They organized the get-together in the city park.

D. They are examples of those who talked to Liz and Bill.

3.What will Liz and Bill do in the future?

A. Go in for publishing

B. Do more television programs.

C. Continue what they are doing

D. Spend more time reading books.

4.How do they like the idea of writing a book?

A. They have decided to wait a year or two.

B. They will think about it carefully

C. They agreed immediately

D. They find it hard to do that.

 

What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing. Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.

Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.
