A subject which seems to have been insufficiently studied by doctors and psychologists is the influence of geography and climate on the psychological and physical health of mankind. There seems no doubt that the general character of the landscape, the relative length of day and night, and the climate must all play a big part in determining what kind of people we are.
It is true that a few studies have been made. Where all the inhabitants of a particular area enjoy exceptionally good or bad health, scientists have identified contributory factors such as the presence or absence of substances like iodine, fluoride, calcium, or iron in the water supply, or perhaps types of land that provide breeding places for pests like mosquitoes or rats.
Moreover, we can all generalize about types of people we have met. Those living in countries with long dark winters are apt to be less talkative and less vivacious than inhabitants of countries where the climate is more equable. And where the olive and the orange grow, there the inhabitants are cheerful, talkative, and spontaneous.
But these commonplace generalizations are inadequate: the influence of climate and geography should be studied in depth. Do all mountain dwellers live to a ripe old age? Does the drinking of wine, rather than beer, result in a sunny and open temperament? Is the strength and height of one of the Kenyan tribes due to their habitual drinking of the blood of cows?
We are not yet sure of the answers to such questions, but let us hope that something of benefit to mankind may eventually result from such studies.

Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “zero-emissions（排放）vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants most all use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators（发电机）. Generators are fueled by something--usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal（地热） plants as well, but by far we get electricity mainly by burning something.
In other words, those "zero-emissions" cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes—“If I can't see it, it's not happening.”  Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas（or another fuel）and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.
A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far -- so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.
　　In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though，all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.

No satisfactory way exists to explain how to form a good idea. You think about a problem until you're tired, forget it, maybe sleep on it, and then flash! When you aren't thinking about it, suddenly the answer arrives as a gift from the gods.
Of course, all ideas don't occur like that but so many do, particularly the most important ones. They burst into the mind, glowing with the heat of creation. How they do it is a mystery but they must come from somewhere. Let's assume they come from the "unconscious." This is reasonable, for psychologists use this term to describe mental processes which are unknown to the individual. Creative thought depends on what was unknown becoming known.
All of us have experienced this sudden arrival of a new idea, but it is easiest to examine it in the great creative personalities, many of whom experienced it in an intensified form and have written it down in their life stories and letters. One can draw examples from genius in any field, from religion, philosophy, and literature to art and music, even in mathematics, science, and technical invention, although these are often thought to depend only on logic and experiment. All truly creative activities depend in some degree on these signals from the unconscious, and the more highly insightful the person is, the sharper and more dramatic the signals become.
A type of creative experience is illustrated by the dreams which came to Descartes at the age of twenty-three and determined his life path. Descartes had unsuccessfully searched for certainty, first in the world of books, and then in the world of men. Then in a dream on November 10, 1619, he made the significant discovery that he could only find certainty in his own thoughts, cogito ergo sum ("I think; therefore, I exist"). This dream filled him with intense religious enthusiasm.
Descartes' experience is representative of countless others in every field of culture. The unconscious is certainly the source of instinctive activity. But in creative thought the unconscious is responsible for the production of new organized forms from relatively disorganized elements.
【小题1】Good ideas come from ________according to the writer.

A．the unconscious

B．creative activities

C．dreams

D．logic and experiments

【小题2】The underlined word “these” (paragraph 3) probably refers to __________.

【小题3】What point can we see in the example of Descartes ?

A．Dreams are the sources of instinctive activities.

B．Dreams sometimes contribute to important discoveries.

C．Geniuses have creative thoughts in their dreams.

D．Important discoveries are always made in dreams.

【小题4】 The best title for this passage may be __________.

A．The Unknown Becoming Known	B．The Role of Dreams
C．The Unconscious and Creative Activities	D．Birth of Bright Ideas

NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people's memories are affected.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. “Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.”
But those who are against the research say that maybe the pills can change people's memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist.
【小题1】The passage is mainly about       .

A．a new medical invention

B．a new research on the pill

C．a way of wiping out painful memories

D．an argument about the research on the pill

【小题2】The drug tested on people can       .

A．cause the brain to fix memories

B．stop people remembering bad experiences

C．prevent body producing certain chemicals

D．wipe out the emotional effects of memories

【小题3】We can infer from the passage that       .

A．experts are not sure about the effects of the pills

B．the pill will certainly stop people's emotional memories

C．taking the pill will do harm to people's physical health

D．the pill has already been produced and used by the American public

【小题4】Which of the following does Rebecca Dresser agree with in the last paragraph?

A．Some memories can ruin people's lives.

B．People want to get rid of bad memories.

C．Experiencing bad events makes us different from others.

D．The pill will reduce people's sufferings from bad memories.

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

It has been argued that an infant under three who is cared for outside the home may suffer because of the separation from his parents．The British psychoanalyst John Bowlby believes that separation from the parents during the sensitive "attachment" period from birth to three may scar （留下疤痕） a child's personality and incline to emotional problems in later life．Some people have drawn the conclusion from Bowlby's work that children should not be sent to day care before the age of three, and many people do believe this．But there are also arguments against such a strong conclusion．
Firstly, anthropologists （人类学家） point out that the hidden love between children and parents found in modem societies does not usually exist in traditional societies．For example, we saw earlier that among the Ngonis the father and mother of a child did not raise their infant alone．But traditional societies are so different from modern societies that comparisons based on just one factor are hard to understand．
Secondly, common sense tells us that day care would not be so widespread today if parents and caretakers found that children had problems with it．But Bowlby's analysis raises the possibility that early day care has delayed effects．The possibility that such care might lead to more mental illness or crime 15 or 20 years later can only be noticed by the use of statistics．Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial．
Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have reported that day care had a neutral of slightly positive effect on children's development．But tests that have had to be used to measure this development are not widely enough accepted to settle the issue．
【小题1】This passage is mainly talking about________．

A．children's personality

B．advantages of infants' early care

C．infants' education

D．negative effect of infant school

【小题2】The phrase "day care   in the first paragraph probably means_____.

A．nursing school	B．baby-sitter
C．boarding school	D．primary school

【小题3】According to Bowlby, children under the age of three______．

A．should not be sent to school

B．should be cared for outside the home

C．will not suffer fro m parental separation

D．don't mind who will look after them

【小题4】The argument against Bowlby's conclusion shows that___．

A．children have problems with day care

B．there is no negative effect on infants who go to school before three

C．there is a long-term effect on infants who go to school before three

D．children who are sent to school before three are sent to mental illness

Botany （植物学） , the study of plants, occupies a particular position in the history of human knowledge．For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest （模糊的）） of insights．It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient．This is logical．Plants are the basis of the food pyramid for all living things even for other plants．They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes．Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each．To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all．
Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows．Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple．When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season—the first, great step in a new association of plants and humans was taken．Grains were discovered and from them flowed the wonder of agriculture: cultivated crops．From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away．
【小题1】What does the writer mean when he says "This is logical" in the first paragraph?

A．Human knowledge of plants is well organized and very detailed．

B．It is not surprising that early humans had a detailed knowledge of plants．

C．There is no clear way to determine the extent of our ancestor's knowledge of plant．

D．It is reasonable to assume our ancestors behave much like people in pre-industrial societies．

【小题4】Human would depend on the controlled production of a few plants for living with

A．the knowledge of plants

Every time you go shopping, the vegetables and fruit look so tempting that you wish you could buy all of them. Some people are lucky and can grow the fruit and vegetables in the gardens that they have. While getting fresh vegetables, they can also achieve great cost cutting.
Mushrooms are expensive and can also go bad very quickly. Mushrooms can also be grown easily in a dark environment. In fact it’s better than growing other vegetables since you really don’t need an outdoor space. A special type of soil that is good for growing mushrooms is easily available.
Actually mushrooms aren’t even vegetables; they are fungi(菌类) and for this reason, you don’t even require sunlight to grow them. Well how does one go about growing mushrooms? You could always Google “growing mushrooms” and you will find a number of mushroom growing kits(工具) available online that area effective and not very expensive either.
Mushrooms can be added to any dish that you cook. Simply use them in pizzas, salads and anything that you pretty much fancy. Grow mushrooms in your own house and use them whenever you want. Fresh mushrooms are tastier than the ones that are stored in your refrigerator.
If you have had a really good crop of mushrooms, then you can even store them. Ideally you should use the white variety of the mushrooms. Simply pick them, slice them and put them on a cookie sheet in a freezer. When they area frozen, just put them in a zip lock and you can use them when you want to. They give a really great taste to the dish that you are making. Thaw them before you use them.
You should try growing mushrooms, since it’s cost-effective. Furthermore, you can eat the fresh mushrooms any time that you want.

Moving to a new town or even a new neighborhood is stressful at any age, but a new study shows that frequent moves in childhood are related to poorer well-being(幸福) in adulthood, especially among people who are more introverted(内向的) or neurotic(神经症的).
The researchers tested the relationship between the number of childhood moves and well-being in a sample of 7108 American adults who were followed for 10 years.
“We know that children who move frequently are more likely to perform poorly in school and have more behavioral problems,” said the study’s lead author Shigehiro Oishi. “However, the long-term effects of moving on well-being in adulthood have been overlooked by researchers.”
The study’s participants, who were between the ages of 20 and 75, were contacted in 1994 and 1995 and were surveyed again 10 years later. They were asked how many times they had moved as children, as well as about their psychological well-being, personality type and social relationships.
The researchers found that the more times people moved as children, the more likely they were to report lower life satisfaction and psychological well-being at the time they were surveyed. The research also showed that those who moved frequently as children had fewer quality social relationships as adults.
The researchers also looked to see if different personality types affected frequent movers’ well-being. Among introverts, the more moves participants reported as children, the worse off they were as adults. “Moving a lot makes it difficult for people to keep long-term close relationships.” Said Oishi. “This might not be a serious problem for outgoing people who can make friends quickly and easily.”
The findings showed neurotic people who moved frequently reported less life satisfaction and poorer psychological well-being than people who did not move as much and people who were not neurotic. However, the number and quality of neurotic people’s relationships had no effect on their well-being, no matter how often they had moved as children. In the article, Oishi thinks this may be because neurotic people have more negative reactions to stressful life events in general.
“We can guess that moving often creates more stress,” Oishi said. “But we need more research on this link before we can conclude that moving often in childhood can, in fact, be dangerous to your health in the long-term.”
【小题1】What can be learnt about the new study from the passage?

B．It was carried out in two periods of time.

C．The participants were mostly old people.

D．The participants had poor health.
