What make a good news photograph?

As you’re thinking about taking news photographs, think about what makes up a good picture.

Most importantly, it will be of interest to a wide audience(观众). It may describe an event in the news: a train crash, a clash in the streets, crazily happy fans the moment the big game is won.

Uniqueness(独一无二) is eye-catching. A picture that no one else took has much more news value than one taken alongside a rank of other photographers. A good news picture will tell a story without words. It will have background by showing the surrounding scene, or show the emotion(情感)on the faces of the people in the picture.

Timeliness is of decisive importance. Whatever the content, a news picture can lose its value in a short space of time. News events move quickly, and the shot of a mini tornado you took last week may have been used for the front page when you took it, but of no interest to a newspaper or a website(网站)a week later.

Control is important. Please remember, absolutely no photo is worth bothering others, putting yourself or others in danger, or getting in trouble with the law.

We’re looking forward to seeing your pictures.

B

Some kids can’t sit still for very long. They have a hard time paying attention to just one thing. They’re easily distracted(分心), they can get very impatient, they hate standing in line or waiting for their turn in a game or activity, they get bored pretty fast, and they may also be impulsive (冲动的) - saying the first thing that comes to mind or interrupting someone else who’s talking.

For certain kids, this problem is so severe that doctors have a name for it: attention deficit hyperactivity disorder, or ADHD (注意力缺陷和多动症). Perhaps as many as one out of every 20 kids under the age of 18 have characteristics of ADHD. Often, these kids have trouble getting through school and facing other difficulties later in life.

Rizzo started developing the Virtual(虚拟的) Classroom in 1999. He wanted to see if he could use it as a tool for testing and treating kids who have attention disorders.

To diagnose (诊断) ADHD, doctors typically test patients by giving them tasks that require attention. As part of one classic test, you watch letters flashing on a computer screen. Every time you see the letter “A” followed by the letter “X”, you have to press the space bar. If you’re paying close attention, you’ll record all of the times when this combination(组合)occurs. If not, you’ll miss some.

The Virtual Classroom makes these tests more efficient, Rizzo says. In one experiment, he gave a group of kids the classic “A-X” test. Instead of looking at a computer screen in a doctor’s office, though, the kids wore headsets that made them feel like they were taking the test in a classroom.

“Basically,” Rizzo says, “we found that the testing usually requires a couple of hours with computer screens in a doctor’s office, but it only takes 20 minutes with virtual reality.”
