[单项选择]While it may be unlikely for a computer to write a best seller, a technology expert has created a computer program that writes its own fiction stories with minimal user input. The program, called MEXICA, is the first to generate original stories based on computerized representations of emotions and tensions between characters.
An Internet survey was carried out to see the popularity of the computer-generated stories, other computerized stories and stories written solely by a human. The result was that readers ranked MEXICA stories highest for flow and coherence, structure, content, suspense and overall quality. Rafael Pérezy Pérez, the creator of MEXICA, explained that a story might begin with something as basic as, "The enemy wounded the knight. The princess cured the knight. The knight killed the enemy. The knight rewarded the princess. The end. "
The program reads characters as variables (变量) and assigns a numerical value, between a continuum(连续体) from -3 to +3, to emo

[单项选择]Computer brain games may not offer the big mental boost many were hoping for, suggests new research, but brain scientists and brain-game experts don’t all agree on the findings.
The study, out this week in Nature, is the largest of its kind, say scientists from England’s Medical Research Council Cognition and Brain Sciences Unit and the Alzheimer’s Society, UK. They said in a Tuesday press briefing that brain-training games, used by millions, may not increase general brain power on other tasks or increase IQ "Participants did get better at games they practiced. The more they trained, the better they got. But there was still no translation to any general improvement in cognitive function," said lead author Adrian Owen, assistant director of Medical Research Council.
The online experiment was sponsored by the BBC and involved more than 11 000 people between the ages of 18 and 60. They were split into three groups, including two groups that played different brain-training ga
A. they can make general brain powerful
