A study reveals that the brain areas that respond when fear is learned through personal experience are al-so triggered when we see someone else in distress.
In the study, participants watched a short video of a person conditioned to fear a so-called neutral stimulus-something people normally wouldn't fear--paired with something they find naturally aversive (令人讨厌的), in this case an electrical shock. The person in the video watched colored squares on a computer screen: When a blue square appeared, the person received a mild shock; when a yellow square appeared, there was no shock. The participant in the video responded with distress when the blue square appeared—he would blink hard, tense his cheek muscles and move his hand. "So it's clear that he's uncomfortable, he's in distress," said study team member Andreas Olsson of Columbia University. "And he's already in distress before he receives the shock, you see him anticipate receiving the shock." By contrast the participant in the video appeared relaxed when the yellow square popped up,
Participants were told they would take part in a similar experiment, and when presented with the blue square, they responded with fear, anticipating a shock, though they were never actually shocked. "Just by watching, they learn themselves," Olsson explained.
This second learning was reflected in the brain. In previous classical conditioning experiments where a fear is learned firsthand, a part of the brain called the amygdala (扁桃核) has been shown to be critical to the development and expression of fears. The scientists monitored the brain activity of each participant during the experiment. Imaging showed that the amygdala responded both when the subjects watched the video of someone else receiving shocks and when they were presented with the blue squares themselves.
"We found that the amygdala is involved both when you're watching somebody receiving shocks, and when you're expecting to receive shocks later on yourself," Olsson said. So it seems that similar processes in the brain are triggered both when fears are experienced first-hand and when they are observed in others.
In the real world, the finding could explain why some people are afraid of things despite little contact with them. "You learn by observing other people's emotional expressions, and what we are showing is that that can be as effective as having those direct experiences yourself," Olsson said. "That's probably one of the reasons why a lot people are having phobias (恐怖症) of certain kinds of stimuli, such as snakes and spiders."

听力原文： We know that, for the most part, the bigger a man's muscles are, the stronger he is. (18[C])Can it be claimed, then, that the larger the brain a man possesses, the smarter he is？ The answer is no.
There are only two animals that have larger brains than man, the whale and the elephant. Yet, in proportion to his size, man's brain is larger. (19[C])Man's usually weighs about three pounds or a little more, and this is about one-fortieth of the weight of his whole body. The whale's body, on the other hand, is a thousand times heavier than its brain, while the elephant's body is about five hundred times as heavy.
But a man who has a large brain is not necessarily more intelligent than one whose brain is smaller. We know that geniuses have existed who have had very large brains, but there have been others whose brains were rather small. Idiots have been known to have very large brains.
(20[D])We do not understand precisely why some people are more intelligent than others. Whether our brains are relatively large or small is less important than that we try to do our very best.
This article is mainly about ______.
A．the weight of a whale's brain
B．the brains of geniuses
C．the size of a person's brain and his intelligence
D．the intelligence of the elephant

The brain is a seemingly endless library, whose sh...
The brain is a seemingly endless library, whose shelves house our most precious memories as well as our lifetime’s knowledge. But is there a point where it reaches capacity. The answer is no, because brains are more sophisticated than that. Instead of just crowding in, old information is sometimes pushed out of the brain for new memories to form. Precious behavioral studies have shown that learning new information can lead to forgetting. But in a new study, researchers demonstrated for the first time how this effect occurs in the brain. In daily life, forgetting actually has clear advantages. Imagine, for instance, that just lost your bank card. The new card you receive will come with a new personal identification number(PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to the relevant information, without old memories interfering. And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference. When we acquire new information, the main automatically tries to incorporate(合并) it within existing information by forming associations. And when we retrieve(检索) information, both the desired and associated but irrelevant information is recalled. The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, and its importance begins to be more appreciated. A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome. In a sense, forgetting is our brain’s way of sorting memories, so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn’t become too full. What does the passage say about forgetting？
A、It can enlarge our brain capacity.
B、It helps get rid of negative memories.
C、It is a way of organizing our memories.
D、It should not cause any alarm in any way.

听力原文：There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, me being more capable than others. But no matter how good a brain he has to begin with an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual — the sort of environment in which he is.
The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, end their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities.
Mark, on the other hand, was raised in the home of rich parents who had been to college. He was read to as a child, sent to a good school, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Peter's score was 85, well below the level he might have attained if reared under average conditions. Mark' s score was 125, twenty-five points above the average and fully forty points higher than his identical brother. Given equal opportunities, the twins would have tested at roughly the same level.

A．Children reared under average conditions possess average intelligence.
B．Lack of opportunity prevents the growth of intelligence.
C．An individual's intelligence is determined chiefly by his environment.
D．Changes of environment produce changes in the brain structure.
