In Year Face
Why is this man so angry? We dont know the reason, but we can see the emotion in his face. Whatever culture you come from, you can understand the feeling that he is expressing. Forty years ago, psychologist Paul Ekman of the University of California, San Francisco, became interested in how peoples faces show their feelings. He took photographs of Americans expressing various emotions. Then he showed them to the Fore people, who live in the jungle in New GuineA．Most of the Fore had never seen foreign faces, but they easily understood Americans expressions of anger, happiness, sadness, disgust, fear, and surprise.
Then Ekman did the same experiment in reverse. He showed pictures of Fore faces to Americans, and the results were similar. Americans had no problems reading the emotions on the Fore peoples faces. Ekmans research gave powerful support to the theory that facial expressions for basic emotions are the same everywhere. He did more research in Japan, Brazil, and Argentina, and got the same results.
According to Ekman, these six emotions are universal because they are built into our brains. They developed to help us deal with things quickly that might hurt us. Some emotional triggers are universal as well. When something suddenly comes into sight, people feel fear, because it might be dangerous. But most emotional triggers are learneD．For example, two people might smell newly cut grass. One person spent wonderful-summers in the country as a child, so the smell makes him happy. The other person remembers working very hard on a farm and being hungry, so he feels sad.
Once we make an emotional association in our brain, it is difficult, and sometimes impossible, to change it. Emotion is the least changeable part of the brain. says Ekman. But we can learn to manage our emotions better. For instance, we can be more aware of things that make us angry, and we can think before we react.
There are many differences between cultures, in their languages and customs. But a smile is exactly the same everywhere.
Paul Ekman studies peoples faces in different cultures.
A．Right
B．Wrong
C．Not mentioned
17、 Ekman did research in several countries and got different results.
A．Right
B．Wrong
C．Not mentioned
18、 Americans get angry more often than the Fore people from New Guinea.
A．Right
B．Wrong
C．Not mentioned
19、 Ekman thinks that some basic emotions are the same everywhere.
A．Right
B．Wrong
C．Not mentioned
20、 Two people might feel different emotions about the same thing.
A．Right
B．Wrong
C．Not mentioned
21、 Fear is the most difficult emotion to change.
A．Right
B．Wrong
C．Not mentioned
22、 People of different cultures smile when they understand each other.
A．Right
B．Wrong
C．Not mentioned

Organic Food: Why?1． Europe is now the biggest market for organic food in the world, expanding by 25 percent a year over the past 10 years． So what is the attraction of organic food for some people? The really important thing is that organic sounds more natural eating organic is a way of defining oneself as natural, good, caring, different from the junk-food-eating masses．
2． Unlike conventional farming, the organic approach means farming with natural rather than man-made, fertilizers and pesticides． Techniques such as crop rotation (轮种) improve soil quality and help organic farmers compensate for the absence of man-made chemicals． As a method of food production organic is, however, inefficient in its use of labor and land; there are severe limits to how much food can be produceD．Also, the environmental benefits of not using artificial fertilizers are tiny compared with the amount of carbon dioxide emitted (排放) by transporting food．
3． Organic farming is often claimed to be safer than conventional fanning． Yet studies into organic fanning worldwide continue to reject this claim． An extensive review by the UK Food Standards Agency found that there was no statistically significant difference between organic and conventional crops． Even where results indicated there was evidence of a difference, the reviewers found no sign that these differences would have any noticeable effect on health．
4． The simplistic claim that organic food is more nutritious than conventional food was always likely to be misleading． Food is a natural product, and the health value of different foods will vary for a number of reasons including freshness, the way the food is cooked, the type of soil it is grown in the amount of sunlight and rain crops have received, and so on． Likewise, the flavor of a carrot has less to do with whether it was fertilized with manure (粪便) or something out of a plastic sack than with the variety of carrot and how long ago it was dug up．
5． Then notion that organic food is safer than normal food is also contradicted by the fact that many of our most common foods are full of natural toxins (毒素)． As one research expert says: People think that the more natural something is, the better it is for them． That is simply not the case． In fact, it is the opposite that is true: the closer a plant is to its natural state, the more likely it is that it will poison you． Naturally, many plants do not want to be eaten, so we have spent 10000 years developing agriculture and breeding out harmful traits from crops．
Paragraph 1__________．
A．Main reason for the popularity of organic food
B．Description of organic farming
C．Factors that affect food health value
D．Testing the taste of organic food
E．Necessity to remove hidden dangers from food
F．Research into whether organic food is better

A．show that organic crops are safer than conventional ones
B．be specially trained

根据下列材料，回答31-45题
Why Dont Babies Talk Like Adults?
Over the past half-century, scientists have settled on two reasonable theories related to babytalk. One states that a young childs brain needs time to master language, in the same way that it does to master other abilities such as physical movement. The second theory states that a childs vocabulary level is the key factor. According to this theory, some key steps have to occur in a logical sequence before sentence formation occurs. Childrens mathematical knowledge develops in the same way.
In 2007, researchers at Harvard University, who were studying the two theories, found a clever way to test them. More than 20000 internationally adopted children enter the US each year. Many of them no longer hear their birth language after they arrive, and they must learn English more or less the same way infants do -- that is, by listening and by trial and error. International adoptees dont take classes or use a dictionary when they are learning their new tongue and most of them dont have a well-developed first language. All of these factors make them an ideal population in which to test these competing hypotheses about how language is learned.
Neuroscientists Jesse Snedeker, Joy Geren and Carissa Shafto studied the language development of 27 children adopted from China between the ages of two and five years. These children began learning English at an older age than US natives and had more mature brains with which to tackle the task. Even so, just as with American-born infants, their first English sentences consisted of single words and were largely bereft (缺乏的) of function words, word endings and verbs. The adoptees then went through the same stages as typical American-born children, though at a faster clip. The adoptees and native children started combining words in sentences when their vocabulary reached the same sizes, further suggesting that what matters is not how old you are or how mature your brain is, but the number of words you know.
This finding -- that having more mature brains did not help the adoptees avoid the toddler-talk stage -- suggests that babies speak in babytalk not because they have baby brains, but because they have only just started learning and need time to gain enough vocabulary to be able to expand their conversations. Before long, the one-word stage will give way to the two-word stage and so on. Learning how to chat like an adult is a gradual process.
But this potential answer also raises an even older and more difficult question. Adult immigrants, who learn a second language rarely, achieve the same proficiency in a foreign language as the average child raised as a native speaker. Researchers have long suspected there is a critical period for language development，after which it cannot proceed with full success to fluency．Yet we still do not understand this critical period or know why it ends．
What is the writers main purpose in Paragraph 2 ?
A．To reject the view that adopted children need two languages．
B．To argue that culture affects the way children learn a language．
C．To give reasons why adopted children were used in the study．
D．To justify a particular approach to language learning．
32、 Snedeker，Geren and Shafto based their study on children who__________.
A．were finding it difficult to learn English
B．were learning English at a later age than US children
C．had come from a number of language backgrounds
D．had taken English lessons in China
33、 What aspect of the adopted childrens language development differed from that of USborn children?
A．The rate at which they acquired language．
B．Their first words．
C．The way they learnt English．
D．The point at which they started producing sentences．
34、 What does the Harvard finding show?
A．Not all toddlers use babytalk．
B．Some children need more conversation than others．
C．Language learning takes place in ordered steps．
D．Not all brains work in the same way．
35、 When the writer says critical period，he means a period when__________．
A．studies produce useful results
B．adults need to be taught like children
C．1anguage learning takes place effectively
D．immigrants want to learn another language

DNA Fingerprinting
DNA is the genetic material found within the cell nucleus of all living things．In mammals the strands of DNA are grouped into structures called chromosomes．With the exception of identical siblings(as in identical twins)，the complete DNA of each individual is unique．
DNA fingerprinting is sometimes called DNA typing．It is a method of identification that compares bits of DNA．A DAN fingerprint is constructed by first drawing out a DNA sample from body tissue or fluid such as hair，blood，or saliva．The sample is then segmented using enzymes，and the segments are arranged by size．The segments are marked with probes and exposed on Xray film，where they form a pattern of black barsthe DNA fingerprint．If the DNA fingerprints produced from two different samples match，the two samples probably came from the same person．
DNA fingerprinting was first developed as all identification technique in 1985．Originally used to detect the presence of genetic diseases，it soon came to be used in criminal investigations and legal affairs．The first criminal conviction based on DNA evidence in the United States occurred in l988．In criminal investigations，DNA fingerprints derived from evidence collected at the crime scene are compared to the DNA fingerprints of suspects．Generally，coups have accepted the reliability of DNA testing and admitted DNA test results into evidence．However，DNA fingerprinting is controversial in a number of areas：the accuracy of the results，the cost oftestin9，and the possible misuse of the technique．
The accuracy of DNA fingerprinting has been challenged for several reasons．First，because DNA segments rather than complete DNA strands are fingerprinted；a DNA fingerprint may not be unique；largescale research to confirm the uniqueness of DNA fingerprinting test results has not been conducted．In addition，DNA fingerprinting is often done in private laboratories that may not follow uniform testing standards and quality controls．Also，since human beings must interpret the test，human error could lead to false results．
DNA fingerprinting is expensive．Suspects who are unable to provide their own DNA to experts may not be able to successfully defend themselves against charges based on DNA evidence．
Widespread use of DNA testing for identification purposes may lead to the establishment of a DNA fingerprint database．
If two sisters are identical twins．their complete DNAs are _________．
A．the same
B．unique
C．different
D．similar
37、 DNA fingerprinting is a technique of _________．
A．grouping DNA strands into structures
B．segmenting DNA with probes
C．constructing body tissues by enzymes
D．identifying a person by comparing DNAs
38、 DNA fingerprinting was first used in _________．
A．criminal investigation
B．animal reproduction
C．private laboratories
D．genetic disease detection
39、 People question the reliability of DNA fingerprinting for _________．
A．the subjective interpretation of test results
B．its complex procedure
C．its large scale research
D．its uniform testing standards
40、 It can be inferred from Paragraph 5 that DNA fingerprinting _________．
A．is costly to the police
B．could be a social issue
C．1s the only way to prove innocence
D．has been a profitable business

On the Trial of the Honey Badger
On a recent field trip to the Kalahari Desert，a team of researchers learn a lot more about honey badgers．The team employed a local wildlife expea Kitso Khama to help them locate and follow the badgers across the desert．Their main aim was to study the badgers，movements and behavior as discreetly(谨慎地)as possible without frightening them away or causing them to change their natural behavior．They also planned to trap a few and study them close up before releasing them in view of the animals reputation；this was something that even Khama was reluctant to do．
The problem with honey badgers is they are naturally curious animals，especially when they see something new，he says．That，combined with their unpredictable nature．can be a dangerous mixture．If they sense you have food，for example，they wont be shy about coming right up to you for something to eat．Theyre actually quite sociable creatures around humans。but as soon as they feel they might be in danger，they can become extremely vicious(凶恶的)．Fortunately this is rare．but it does happen．
The research confirmed many things that were already known．As expected，honey badgers ate any creatures they could catch and kill．Even poisonous snakes，feared and avoided by most other animals，were not safe from them．The researchers were surprised，however．by the animals fondness for local melons，probably because of their high water content．Preciously researchers thought that the animal got all of its liquid requirements from its prey(猎物)．The team also learnt that，contrary to previous research findings，the badgers occasionally formed loose family groups．They were also able to confirm certain results from previous research．including the fact that female badgers never socialized with each other．
Following some of the male badgers was a challenge，since they can cover large distances in a short space of time．Some hunting territories cover more than 500 square kilometers．Although they seem happy to share these territories with other males，there are occasional fights over an Important food source，and male badgers Call be as aggressive towards each other as they are towards other species．
As the badgers became accustomed to the presence of people，it gave the team the chance to get up close to them without being the subject of the animals curiosityor sudden aggression. The badgers eating patterns, which had been disrupted, to normal. It also allowed the team to observe more closely some of the other creatures that form working associations with the honey badger, as these seemed to badgers relaxed attitude when near humans.
Why did the wild life experts visit the Kalahari Desert?
A．To find where honey badgers live.
B．To catch some honey badgers for food.
C．To find out why honey badgers have a bad reputation.
D．To observe how honey badgers behave.
42、 What does Kitso Khama say about honey badgers?
A．They are always looking for food.
B．They do not enjoy human company.
C．It is common for them to attack people.
D．They show interest in things they are not familiar with.
43、 What did the team find out about honey badgers?
A．There were some creatures they did not eat.
B．They were afraid of poisonous creatures.
C．Female badgers did not mix with male badgers.
D．They may get some of the water they needed from fruit.
44、 Which of the following is a typical feature of male badgers?
A．They dont run very quickly.
B．They defend their territory from other badgers.
C．They hunt over a very large area.

Toads are Arthritis and in Pain
Arthritis is an illness that can cause pain and swelling in your bones． Toads, a big problem in the north of Australia, are suffering from painful arthritis in their legs and backbone, a new study has shown． The toads that jump the fastest are more likely to be larger and to have longer legs． (46)．
The large yellow toads, native to South and Central America, were introduced into the north-eastern Australian state of Queensland in 1935 in an attempt to stop beetles and other insects from destroying sugarcane crops． Now up to 200 million of the poisonous toads exist in the country, and they are rapidly spreading through the state of Northern Territory at a rate of up to 60 km a year． The toads can now be found across more than one million square kilometers．(47) A Venezuelan poison virus was tried in the 1990s but had to be abandoned after it was found to also kill native frog species．
The toads have severely affected ecosystems in AustraliA．Animals, and sometimes pets, that eat the toads die immediately from their poison, and the toads themselves eat anything they can fit inside their mouth． (48)
A co-author of the new study, Rick Shine, a professor at the University of Sydney, says that little attention has been given to the problems that toads face． Rick and his colleagues studied nearly 500 toads from Queensland and the Northern Territory and found that those in the latter state were very different． They were active, sprinting down roads and breeding quickly． According to the results of the study, the fastest toads travel nearly one kilometer a night．(49) But speed and strength come at a price -- arthritis of the legs and backbone due to constant pressure placed on them．
In laboratory tests, the researchers found that after about 15 minutes of hopping, arthritic toads would travel less distance with each hop (跳跃)． (50) These toads are so programmed to move, apparently, that even when in pain the toads travelled as fast and as far as the healthy ones, continuing their relentless march across the landscape．
____________
A．But this advantage also has a big drawback -- up to 10% of the biggest toads suffer from arthritis．
B．The task now facing the country is how to remove the toads．
C．But arthritis didnt slow down toads outside the laboratory．
D．Toads with longer legs move faster and travel longer distances while the others are being left behind．
E．Toads are not built to be road runners -- they are built to sit around ponds and wet areas．
F．Furthermore, they soon take over the natural habitats of Australias native species．
