Computer reconstructions of ancient skulls (头骨) show that our ancestors had ears built like ours as far back as 350,000 years ago. The ears of social mammals(哺乳动物) are typically designed to recognize sounds made by fellow species members. "So, humanlike ears suggest humanlike speech", say researchers from Spain.
Anthropologists(人类学家) don't know for sure when people started talking. To get a better idea, the new study focused on a group of fossils(化石) from a place in Spain called Sima de los Huesos. The fossils belong to a species(人种) called Homo heidelbergensis. Modem people did not evolve from H. heidelbergensis, but an ancient group called Neandertals might have.
Using a computerized scanner(扫描机), the researchers measured ear structures on the remains. Then, they used information about living people to make three-dimensional (三维的)computer models of what the ancient ears looked like. Finally, they measured how sound would pass through the model ears.
The results showed that the ears could handle almost exactly the stone range of sounds that our ears can today. The researchers suggest that hearing and talking developed in a common ancestor shared by both Neandertals and modern people.
Other experts are more skeptical(怀疑的). Some studies have turned up conflicting results about the ears and vocal chords(声带) of Neandertals. And anyway, hearing could have evolved long before talking. The two don't necessarily go together.
If it's true that our ancestors could talk more than 350,000 years ago, that brings up another question. What kinds of things did they talk about？
"Social mammals" in the second paragraph means "______".
A．our ancestors
B．a kind of ancient human tribe
C．Homo heidelbergensis
D．Neandertals

听力原文：M: Did you watch undersea Discover), last night？
W: No, I missed it. Did you？
M: Yeah, it was pretty good...It was about barnacles.
W: Hmm.
M: You know how they stick themselves to stuff in the ocean ... like rocks or boats？
W: Uh—huh.
M: Well, they do that when they're young, and then they stay in the same place forever.
W: It figures. Have you ever tried removing one of those things. Last summer I tried to scrape some off a pier...I had to give up after a while. You'd think they wouldn't be able to stick like that undcrwater.
M: That's one. reason scientists are-trying to figure out what their glue's made of. It's one of the strongest adhesive in nature, and it's a natural protein, so it probably wouldn't be harmful like some synthetic glues.
W: Really？
M: Yes. these biomedical researchers were talking about its possible uses. Orthopedists could use it for mending broken bones; or it could be used in dentistry.
W: I wish I'd seen that.

Learning Disabilities
Learning disabilities are very common. They affect perhaps 10 percent of all children. Four times as many boys as girls have learning disabilities.
Since about 1970, new research has helped brain scientists understand these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the train is organized.
You cannot look at a child and tell if he or she has a learning disability. There is no outward sign of the disorder. So some researchers began looking at the brain itself to learn what might be wrong.
In one study, researchers examined the brain of a learning-disabled person who had died in an accident. They found two unusual things. One involved cells in the left side of the brain, which control language. These cells normally are white. In the learning disabled person, however, these cells were gray. The researchers also found that many of the nerve cells were not in a line the way they should have been. The nerve cells were mixed together.
The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind proposed that learning disabilities resulted mainly from problems in the left side of the brain. He velieved this side of the brain failed to develop normally. Probably, he said, nerve cells there did not conncts as they should. So the brain was like an electrical device in which the wires were crossed.
Other researchers did not examine brain tissue. Instead, they measured the brain’s electrical activity and made a map of the electrical signals.
Frank Dully experimented with this technique at Children’S Hospital Medical Centre in Boston. Doctor Dully found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Doctor Duffy said his research is evidence that disabilities involve damage to a wide area of the brain, not just the left side.
第41题 Which of the following is NOT mentioned in the passage？____________.
A Learning disabilities may result from the unknown area of the train
B learning disabilities may result from damage to a wide area of the train
C Learning disabilities may result from abnormal organization of the train cells.
D Leaning disabilities may result from problems in the left side of the brain.

Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing (压制) yourself; almost like the character is possessing you." Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments. Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party？ And would they tell their parents that they had fallen in love？ Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.
The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character. The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前额皮质) linked to the sense of self, compared with when the actors were responding as themselves.
However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone — it involves embodying (体现) the text and language.
1.How did Dr Brown's team conduct their research？（）
A.By scanning the brain activity of some actors
B.By doing a survey with some theatre goers
C.By interviewing some theatre teachers
D.By consulting some experienced researchers
2. Which of the following is Not True according to the research？（）
A. When actors are acting, they are suppressing themselves
B. The subjects (实验的研究对象)were all theatre students
C. The subjects’ brains were scanned in a series of experiments
D. The subjects’ brain activity differed depending on the situation being tested
E. The subjects were asked different questions
3.What is the finding of Dr Brown's research？（）
A.Acting is not as mysterious as people think
B.Actors' brain activity differs when they are acting
C.Acting is far more than pretending to be the character
D.Actors' brain activity is more active when they are in character
4.How did Philip Davis react to the research？（）
A.He supported it
B.He doubted it
C.He explained it
D.He advocated it
5.What is the text mainly about？（）
A.A debate of how the brain functions
B.A play written by Shakespeare
C.A research on the brain activity of actors
D.A report of the cooperation of scientists and actors

Napping to a Healthier Heart？
Researchers say they have developed a simple test that can tell if a person with heart disease isl ikely to suffer a heart attack.The test measures levels of a protein in the blood．The researchers say people with high levels of this protein are at high risk of heart attack，heart failure or stroke．
Kirsten Bibbins—Domingo 0f the University of California in San Francisco led the team．For about tour years，they studied almost one thousand patients with heart disease．The researchers tested the heart disease patients for a protein called NT—proBNP．Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack，heart failure or stroke．
The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men，s0 the researchers could not
say for sure that the results are also true for women．They say the patients with the highest levels of NT—proBNP were older and had other problems like diabetes or high blood pressure．
Other researchers say more tudies are needed to confirm if knowing the protein levels of a heart patient should affect that person’s treatment．They also would like to know if more aggressive treatment could reduce the patient’s chance of a heart attack or stroke．The study appeared in the Journal of the American Medical Association．
Could a little sleep during the middle of the day reduce the risk of a heart attack ？ An unrdated study earlier this month in the Archiyes of Internal Medicine suggests that the answer may be yes In countries like the United Stares，afternoon Haps are mosny for childten． But they are common for adults in Mediterranean countries．And these countries generally have lower rates of heart disense.So scientists in the United Stares and Greece wondered if naps could play a part．Twenty—three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty—minute naps three times a week had a thirty—seven percent lower risk of death from heart pmblems than people who did not take naps.
The researchers say napping may improve heart hearlth by reducing stress.They say the research suggests that naps are especially good for working men．But they say not enoush female subjects died during the study to judge the benefits for women．
