While some scientists overlook the existence of a sixth sense for danger, a new research from Washington University in St. Louis has discovered a brain area that clearly acts as an early warning system and helps us adjust our behavior to avoid dangerous situations.

"Our brains are better at picking up not obvious warning signs than we previously thought," said Joshua Brown, a PhD in psychology in the issue of the journal Science.

The findings offer exact scientific evidence for a new way to form a concept of the complex control processes taking place in and around the ACC, a brain area located near the top of the frontal lobes(耳垂) and along the walls that divide the left and right hemispheres(大脑半球).

"In the past, we found activity in the ACC when people had to make a difficult decision, or after they make a mistake," Brown said. "But now we find that this brain area can actually learn to recognize when you might make a mistake, even before a difficult decision has to be made. So the ACC appears to act as an early warning system—— it learns to warn us in advance when our behavior might lead to a negative outcome, so that we can be more careful and avoid making a mistake."

By providing a clearer picture by which we self monitor and control our behavior, the study is an important step in efforts to develop more effective treatments for mental illnesses. It also provides a new way of understanding inappropriate behaviors that often accompany mental illnesses.

"Our results suggest how injury of the ACC can lead to breakdowns in the early warning system, so that the brain fails to stop or control inappropriate behavior ahead of time," said Brown. "On the other hand, in those persons with mental disorder, the ACC might warn us of an upcoming problem even when no problem is in the existence."

Known to be an important part of the brain's control system, the ACC is believed to help adjust between cold, hard, fact-based reasoning and emotional responses, such as love, fear or expectation.

1.According to the passage, the ACC____________.

A. refers to the sixth sense for danger

B. deals with obvious warning situations

C. connects the left and right hemispheres

D. sends warning messages in advance

2.The new research is beneficial because it ________ .

A. provides a new way of avoiding mistakes

B. adjusts emotional responses in time of danger

C. helps find better treatments for mental illnesses

D. assists people in predicting and avoiding danger

3.The new research helps us understand _________.

A. why we are likely to make mistakes when the ACC is badly injured

B. why people with illnesses usually have so many strange behaviors

C. how the ACC works when something dangerous happens

D. how our brain warns us of failure in advance

When author Nicholas Carr began researching his book on whether the Internet is ruining our minds, he restricted his online access and e-mail. His new book argues the latest technology renders us less capable of deep thinking. Carr found himself so distracted (分心的) that he couldn’t work on the book while staying as connected. After first feeling confused by his sudden lack of online connection, he was able to stay focused on one task for a long period within several weeks.

Reading on the Internet has changed how we use our brains. Facing much text, video, music, links to other web pages and blogs, our minds have become used to skimming and scanning information. As a result, we have developed sharper skills at making fast decision, particularly visual ones, Carr wrote.

But now most of us seldom read books, long articles that would help us focus. We are becoming more like librarians than scholars who digest and interpret information. That lack of focus hinders (妨碍)our long-term memory, leading many of us to feel distracted, he wrote.

“What we are losing is a whole other set of mental skills, the ones that require not the shifting of our focus but the maintaining of our focus,” Carr said, adding that for centuries books shielded (保护)our brains from distraction, focusing our minds on one topic at a time.

But with devices such as Apple’s iPad becoming common, Carr predicts books too will change. “New forms of reading always require new forms of writing,” he wrote. Carr has a suggestion for those who feel web surfing has left them incapable of concentration — slow down, turn off the Internet and practice the skills of contemplation (思考)and reflection. “It is pretty clear from the brain science that if you are constantly distracted, you are not going to think in the same way that you would think if you paid attention.”

1.The underline word “renders” can be replaced by ________.

A.causes

B.prevents

C.protects

D.sharpens

2.What topic is Carr’s new book mainly concentrating on?

A.Whether there is no need for us to surf the Internet

B.How the Internet changes our method of writing

C.Whether our minds are being influenced by the Internet

D.What we should do when we are surfing the Internet

3.What did Carr feel after he limited his time online several weeks later?

A.Anxious

B.Concentrated

C.Relaxed

D.Puzzled

4.Carr says we are becoming kind of librarians mainly because__________.

A.we are able to find information online quickly

B.we often feel bored of the information online

C.we are good at using our mental skills online

D.we have to focus on so much information online

5.For those who are often distracted by the Internet, Carr suggests that they should _________.

A.read more books besides surfing the Internet

B.spend less time in surfing the Internet at a deep night

C.often slow down their pace of modern living

D.often get away from the disturbing of the Internet
