Fear may be in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting (收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain reacts to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr. Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see-and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner (扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.
"We have found an important mechanism by which the heart and brain 'speak' to each other to change our feelings and reduce fear, "Dr. Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety (焦虑) disorders, and also for those who may be suffering from serious stress disorder."
1.What is the finding of the study?
A.One's heart influences how he feels fear.
B.Fear is a result of one's heartbeat.
C.Fear can't be felt because of one's relaxed heartbeat.
D.One's fast heartbeats are likely to cause fear.
2.The study was carried out by studying________.
A.volunteers' heartbeats when they saw terrible pictures
B.the time volunteers saw fearful pictures and their health conditions
C.volunteers' reactions to horrible pictures and results from their brain scans
D.different pictures shown to volunteers and their heartbrain communication
3.Which of the following is closest in meaning to "mechanism" in Paragraph 6?
A.Order. B.System. C.Machine. D.Treatment.
4.This study may contribute to________.
A.treating anxiety and stress better
B.explaining the cycle of fear and anxiety

According to a new study, cats may be just as smart as dogs. Both cats and dogs may have episodic memory(情景记忆), similar to that of human beings.
The discovery shows that cats can recall memories of positive experiences like eating a delicious snack. The study was a test of episodic memory. Episodic memory means memory of past experiences that happened at a special time and place.
In the test, cats were led to four open bowls of food. They were allowed to eat from two of them. After fifteen minutes, empty bowls took the place of the old ones. Then the same cats returned to look for food again. They spent more time searching for the old bowls.
It seemed that the cats were able to remember the information of “what” and “where” about the bowls. This discovery suggests that they may have episodic memory. However, it’s still not clear whether cats can truly experience past memories in the same way as human beings do. “It’s difficult to know whether the cats can subjectively(主观地)remember the experience,” Nick Diamond, a researcher at the University of Toronto, explained.
Still, the test plays an important role in the development of memory research in animals. “It opens the door to new studies. How long can cats’ memories last? We may do some research on this in the future,” Professor Laurie Santos from Yale University told BBC News.
The road to new discoveries is long and difficult. Though there are lots of problems to be solved and discussed along the way, such studies do lead us a step closer to the final success.
1._______ may have episodic memory.
A. Dogs B. Pandas C. Elephants D. Sheep
2.It seems that cats can recall memories of their _____ experiences.
A. happy B. sad C. scary D. unusual
3.What can we learn from the study?
A. Cats can subjectively remember past experiences.
B. The cats spent more time searching for empty bowls.
C. Cats are smarter than dogs and as smart as humans
D. Cats may have episodic memory similar to that of humans.
4.According to the fifth paragraph, scientists may do some research on ____ in the future.
A. whether dogs can recall memories like cats
B. why cats only remember good experiences
C. how long cats’ memories can last
D. how humans recall past memories
5.What does the writer think of the study?
A. It has already solved many problems.
B. It helps memory research in animals.
C. It has nothing to do with other studies.
D. It is a waste of money and time.

As many as 10 of the 17 kinds of penguins(企鹅)may be in danger of disappearing. The number of penguins have decreased(减少) by 30% since 1987.
Penguins are black and white birds that live in the southern part of the world. They are common in South America,New Zealand,Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly,but they are fine swimmers. Penguins eat fish and krill(磷虾).
The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖). Besides,many adult penguins die of hunger.
Widespread(广泛的) fishing,exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies,including wild dogs,sharks,seals and sea lions.
News about penguins is not all bad,however. Several years ago,oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild. Now these South African penguins are reproducing in higher numbers than before the oil leaking.
1.Penguins ___________.
A.can swim better than fly B.can be found near Oceania (大洋洲)
C.eat fish only冬腊月 D.live only in cold waters.
2.Which of the following is NOT the cause of penguin's decrease in numbers?
A.Oil searching. B.Widespread fishing.
C.Human's killing. D.Warming of the oceans.
3. Why are the penguins in South Africa reproducing in higher numbers than before the oil leaking?
A.Because people removed the ship.
B.Because people sent a lot of penguins to the wild.
C.Because people helped the penguins.
D.Because people treated the penguins well.
