Two skulls（头颅骨）found in Africa have been identified as the oldest human remains known to science. The fossilized（化石）bones found in 1967 were originally thought to be 130,000 years old. But a re-dating of rock layers near those which yielded the fossils showed they are actually about 195,000 years old---from the time modern humans appeared. The skulls, known as Omo I and II, push back the known presence of Homo sapiens（现代人）in Africa by 40,000 years. The previous oldest Homo sapiens skulls, dated to between 154,000 and 160,000 years old, were found near a village called Herto in the afar region of eastern Ethiopia. Omo I and II were unearthed by famous paleontologist（古生物学家）Richard Leakey along the Omo River in southern Ethiopia, near the town of Kibish. Omo I’s more modern features led to disagreement among experts over whether they were the same age. The rocks in which they were found show they are, said an Australian archaeologist Prof. Ian McDougall, who made the discovery. He told scientific journal “Nature”: “Omo I and Omo II are relatively securely dated to 195,000 years old, making them the oldest anatomically（解剖学的）modern human fossils yet recovered”

1.By which means could scientists tell the age of fossils they have found?

A. The bones of the fossils.             B. The place where they were found.

C. The history of humans.              D. Identifying the rock layers of the fossils.

2.How many years older have modern humans become by the new discovery?

A. 130,000.    B. 40,000.    C. 195,000.     D. Between 154,000 and 160,000.

3.Which of the following statements are NOT true according to the passage?

A. The new discovery of the skulls and the research proved the modern humans might have started in Africa.

B. Prof. Ian McDougall thought Omo I and II were the oldest human fossils discovered.

C. Prof. Ian McDougall discovered that Omo I and II were not the same age.

D. Omo I and II were discovered in southern Ethiopia.

When people get a bad toothache, they often have to eat soft, easily chewed food.  _____ That’s the conclusion of a zoologist at the Field Museum of Natural History in Chicago and a dentist who works on carnivores (食肉动物).

_____ Every once in a while, however, a lion will go on a human-eating diet.  The most famous such tragedy happened in 1898, when two lions killed and ate 135 railway workers in Kenya. 

Examining the preserved skulls of the two big lions, zoologist Bruce Patterson and dentist Ellis Neiburger found that both animals had been suffering from several dental and jaw problems. ______ Canines are pointed teeth that hunting animals use for gripping and piercing prey . 

       The two lions might have been so badly disabled that they couldn’t bite down forcefully, say the researchers. Consequently, the lions might have abandoned their normal, more difficult prey and turned to humans.  Patterson said “_________ We’re very slow, we don’t hear very well, and we don’t see very well in the darkness.”

       __________ It was inspired partly by the work of Jim Corbett, a tiger hunter in India in the 1930s.  Corbett was regularly called in to hunt tigers that had been dining on Indian villagers. Time after time, Patterson discovered that the killer tigers were suffering from some ill-healthy conditions.

What do consumers really want? That’s a question market researchers would love to answer. But since people don’t always say what they think, marketers would need direct access to consumers’ thoughts to get the truth.
Now, in a way, that is possible. At the “Mind of the Market” laboratory at Harvard Business School, researchers are looking inside shoppers’ skulls to develop more effective advertisements and marketing styles. Using imaging techniques that measure blood flow to various parts of the brain, the Harvard team hopes to predict how consumers will react to particular products and to discover the most effective ways to present information. Stephen Kosslyn, a professor of psychology at Harvard, and business school professor Gerald Zaltman, oversee the lab. “The goal is not to influence people’s preferences,” says Kosslyn, “just to speak to their actual desires."
The group’s findings, though still preliminary (初步的), could change how firms develop and market new products. The Harvard group use position emission tomography (PET) scans to monitor the brain activity. These PET scans, along with other imaging techniques, enable researchers to see which parts of the brain are active during specific tasks(such as remembering a word).Correlations (相互关系) have been found between blood flow to specific areas and future behavior. Because of this, Harvard researchers believe the scans can also predict future purchasing patterns. According to an unpublished paper the group produced, “It is possible to use these techniques to predict not only whether people will remember and have specific emotional reactions to certain materials, but also whether they tend to want those materials months later.”
The Harvard group is now moving into the next stage of experiments. They will explore how people remember advertisements as part of an effort to predict how they will react to a product after having seen an ad. The researchers believe that once key areas of the brain are identified, scans on about two dozen volunteers will be enough to draw conclusions about the reactions of specific sections of the population. Large corporations-including Coca Cola, Eastman Kodak, General Motors, and Hallmark-have already signed up to fund further investigations.
For their financial support, these firms gain access to the experiments but cannot control them．If Kosslyn and Zahman and their team really can read the mind of the market, then consumers may find it even harder to get those advertising jingles-out of heir heads.
66. Which of the following statements can be the best title for this passage?
A. Reading the Mind of the Market.    
B. Influencing the Customers’ Choice.
C. Influencing the Style of Advertising.      
D. Experimenting with the Way to Foretell
67. Why do the Harvard researchers use scientific technology in the experiments?
A. Because they want to find a better way to persuade people into purchasing patterns in the future in the different market.
B. Because they don’t trust the findings already done by other researchers.
C. Because they want to see how particular products can influence consumers and find out the most effective ways to advertise.
D.Because they think the marketing strategies can actually be changed after the experiments.
68. According to the passage, which of the following is NOT true?
A. People sometimes hide their true feelings when questioned by the marketing surveyors.
B. Stephen Kosslyn and Gerald Zaltman are in charge of the experiment and think ill of the study.
C. Harvard researchers have found some relation between people’s brain and future behavior.
D. Many large companies finance the Harvard group’s further investigations.
69. What does “to speak to” in the 2nd paragraph mean?
A. To communicate with. B. To say to.    C. To talk to.      D. To respond to.
70. The last sentence of the passage implies that ___________.
A. it is very likely that customers will buy unnecessary things just depending on the ads in the future.
B. in fact, the real purpose of Harvard group’s research is to attract more consumers into the market.
C. Coca Cola or the General Motors can exploit the findings of the experiments in their own marketing.
D. Consumers may find it more difficult to get out of the advertising jungle and it may cause them headaches.

If the eyes are the romantic’s window into the soul, then the teeth are an anthropologist’s ( 人类学家 ) door to the stomach.

   In a study published last month in the journal Science, Peter Ungar of the University of Arkansas and his partner, Matt Sponheimer of the University of Colorado, US, examined the teeth of our early human ancestors to find out what they were really eating.

   They already knew that different foods cause different marks on teeth. Some cause scratches, while others cause pits (坑).The carbon left on teeth by different foods is also different. Tropical grasses, for example, leave one kind of carbon, but trees leave another kind because they photosynthesized ( 光合作用 ) differently.

   Traditionally, scientists had looked at the size and shape of teeth and skulls ( 头骨 ) to figure out what early humans ate. Big flat teeth were taken to be signs that they ate nuts and seeds, while hard and sharp teeth seemed good for cutting meat and leaves. But this was proven wrong.

   The best example was the Paranthropus (傍人), one of our close cousins, some of which lived in eastern Africa. Scientists used to believe Paranthropus ate nuts and seeds because they had big crests(突起)on their skulls, suggesting they had large chewing muscles and big teeth. If this had been true, their teeth should have been covered with pits like the surface of the moon. They would also have had a particular type of carbon on their teeth that typically comes from tree products, such as nuts and seeds.

   However, when the two scientists studied the Paranthroupus, it turned out to have none of these characteristics. The teeth had a different kind of carbon, and were covered with scratches, not pits. This suggests they probably ate grass, not nuts and fruit stones. It was the exact opposite of what people had expected to find.

   Carbon “foodprints” give us a completely new and different insight into what different species ate and the different environments they lived in. If a certain species had the kind of carbon on its teeth that came from grasses, it probably lived in a tropical grassland, for example.

1.The underlined sentence in Paragraph 1 probably means that _____.

A. anthropologists can study the structure of human stomachs by studying their teeth.

B. anthropologists can study the diet of early humans by studying their teeth

C. anthropologists can learn whether humans were healthy by looking at their teeth

D. anthropologists can get the most useful information about humans from their teeth

2.According to Paragraph 3 to 5, which of the following statements is TRUE?

A. Scratches on teeth are caused by eating nuts or seeds.

B. Pits on teeth are caused by eating grass or leaves.

C. Early humans with hard and sharp teeth ate meat and leaves.

D. Different foods leave different marks and carbon on teeth.

3.The example of the Paranthropus was mentioned in the article in order to _____.

A. tell readers that they are one of our close cousins living in eastern Africa

B. tell readers they had different eating habits from modern humans

C. prove that size and shape of skulls does not show accurately what early humans ate

D. tell readers that living environment makes a difference to skull structure
