I’ve been writing for most of my life. The book Writing Without Teachers introduced me to one distinction(区别)and one practice that has helped my writing processes tremendously. The distinction is between the creative mind and the critical mind. While you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so.
  Trying to criticize writing on the fly is possibly the single greatest barrier to writing that most of us encounter. If you are listening to that 5th grade English teacher correct your grammar while you are trying to capture a fleeting (稍纵即逝的) thought, the thought will die. If you capture the fleeting thought and simply share it with the world in raw form, no one is likely to understand. You must learn to create first and then criticize if you want to make writing the tool for thinking that it is.
  The practice that can help you past your learned bad habits of trying to edit as you write is what Elbow calls “free writing.” In free writing, the objective is to get words down on paper non-stop, usually for 15-20 minutes. No stopping, no going back, no criticizing. The goal is to get the words flowing. As the words begin to flow, the ideas will come from the shadows and let themselves be captured on your notepad or your screen.
  Now you have raw materials that you can begin to work with using the critical mind that you’ve persuaded to sit on the side and watch quietly. Most likely, you will believe that this will take more time than you actually have and you will end up staring blankly at the pages as the deadline draws near.
  Instead of staring at a blank start filling it with words no matter how bad. Halfway through your available time, stop and rework your raw writing into something closer to finished product. Move back and forth until you run out of time and the final result will most likely be far better than your current practices.
1 When the author says the creative mind and the critical mind “cannot work in parallel” in the writing process, he means                .
A．one cannot use them at the same time B．they cannot be regarded as equally important
C．they are in constant conflict with each other D．no one can be both creative and critical
2 What prevents people from writing on is                .
A．putting their ideas in raw form B．ignoring grammatical soundness
C．attempting to edit as they write D．trying to capture fleeting thoughts
3 What is the chief objective of the first stage of writing?
A．To organize one’s thoughts logically. B．To get one’s ideas down.
C．To choose an appropriate topic.         D．To collect raw materials.
4 One common concern of writers about “free writing” is that                .
A．it overstresses the role of the creative mind B．it does not help them to think clearly
C．it may bring about too much criticism D．it takes too much time to edit afterwards
5 In what way does the critical mind help the writer in the writing process?
A．It allows him to sit on the side and observe. B．It helps him to come up with new ideas.
C．It saves the writing time available to him. D．It improves his writing into better shape.

"The world's environment is surprisingly healthy. Discuss." If that were an examination topic, most students would tear it apart, offering a long list of complaints: from local smog ( 烟雾 ) to global climate change, from the felling ( 砍伐 ) of forests to the extinction of species. The list would largely be accurate, the concern legitimate. Yet the students who should be given the highest marks would actually be those who agreed with the statement. The surprise is how good things are, not how bad.
　After all, the world's population has more than tripled during this century, and world output
has risen hugely, so you would expect the earth itself to have been affected. Indeed, if people lived, consumed and produced things in the same way as they did in 1900 (or 1950, or indeed 1980), the world by now would be a pretty disgusting place: smelly, dirty, toxic and dangerous.
　But they don't. The reasons why they don't, and why the environment has not been mined,
have to do with prices, technological innovation, social change and government regulation in re-
sponse to popular pressure. That is why, today's environmental problems in the poor countries
ought, in principle, to be solvable.
Raw materials have not run out, and show no sign of doing so. Logically, one day they must: the planet is a finite place. Yet it is also very big, and man is very ingenious. What has happened is that every time a material seems to be running short, the price has risen and, in response, people have looked for new sources of supply, tried to find ways to use less of the material, or looked for a new substitute. For this reason prices for energy and for minerals have fallen in real temp3s during the century. The same is true for food. Prices fluctuate, in response to harvests, natural disasters and political instability; and when they rise, it takes some time before new sources of supply become available. But they always do, assisted by new famp3ing and crop technology. The long temp3 trend has been downwards.
　It is where prices and markets do not operate properly that this benign ( 良性的 ) trend begins to stumble, and the genuine problems arise. Markets cannot always keep the environment healthy. If no one owns the resource concerned, no one has an interest in conserving it or fostering it: fish is the best example of this.
1. According to the author, most students________.
A) believe the world's environment is in an undesirable condition
B) agree that the environment of the world is not as bad as it is thought to be
C) get high marks for their good knowledge of the world's environment
D) appear somewhat unconcerned about the state of the world's environment
2. The huge increase in world production and population ________.
A) has made the world a worse place to live in
B) has had a positive influence on the environment
C) has not significantly affected the environment
D) has made the world a dangerous place to live in
3. One of the reasons why the long-temp3 trend of prices has been downwards is that________.
A) technological innovation can promote social stability
B) political instability will cause consumption to drop
C) new famp3ing and crop technology can lead to overproduction
D) new sources are always becoming available
4. Fish resources are diminishing because________.
A) no new substitutes can be found in large quantities
B) they are not owned by any particular entity
C) improper methods of fishing have mined the fishing grounds
D) water pollution is extremely serious
5. The primary solution to environmental problems is________.
A) to allow market forces to operate properly
B) to curb consumption of natural resources
C) to limit the growth of the world population
D) to avoid fluctuations in prices

Low-level slash-and-burn farming doesn’t harm rainforest. On the contrary, it helps farmers and improves forest soils. This is the unorthodox view of a German soil scientist who has shown that burnt clearings in the Amazon, dating back more than 1,000 years, helped creates patches of rich, fertile soil that farmers still benefit from today.
  Most rainforest soils are thin and poor because they lack minerals and because the heat and heavy rainfall destroy most organic matter in the soils within four years of it reaching the forest floor. This means topsoil contains few of the ingredients needed for long-term successful farming.
  But Bruno Glaser, a soil scientist of the University of Bayreuth, has studied unexpected patches of fertile soils in the central Amazon. These soils contain lots of organic matter.
  Glaser has shown that most of this fertile organic matter comes from “ black carbon” --- the organic particles from camp fires and charred (烧成炭的) wood left over from thousands of years of slash-and-burn farming. “ The soils, known as Terra Preta, contained up to 70 times more black carbon than the surrounding soils,” says Glaser.
  Unburnt vegetation rots quickly, but black carbon persists in the soil for many centuries. Radiocarbon dating shows that the charred wood in Terra Preta soils is typically more than 1,000 years old.
  “Slash-and-burn farming can be good for soils provided it doesn’t completely burn all the vegetation, and leaves behind charred wood,” says Glaser. “It can be better than manure (粪肥).” Burning the forest just once can leave behind enough black carbon to keep the soil fertile for thousands of years. And rainforests easily regrow after small-scale clearing. Contrary to the conventional view that human activities damage the environment, Glaser says: “ Black carbon combines with human wastes is responsible for the richness of Terra Preta soils.”
  Terra Preta soils turn up in large patches all over the Amazon, where they are highly prized by farmers. All the patches fall within 500 square kilometers in the central Amazon. Glaser says the widespread presence of pottery (陶器) confirms the soil’s human origins.
  The findings add weight to the theory that large areas of the Amazon have recovered so well from past periods of agricultural use that the regrowth has been mistaken by generations of biologists for “virgin” forest.
  During the past decade, researchers have discovered hundreds of large earth works deep in the jungle. They are up to 20 meters high and cover up to a square kilometer. Glaser claims that these earth works, built between AD 400 and 1400, were at the heart of urban civilizations managed to feed themselves.
1. We learn from the passage that the traditional view of slash-and-burn farming is that _______.
A) it does no harm to the topsoil of the rainforest
B) it destroys rainforest soils
C) it helps improve rainforest soils
D) it diminishes the organic matter in rainforest soils
2. Most rainforest soils are thin and poor because _________.

B) black carbon is washed away by heavy rains
C) organic matter is quickly lost due to heat and rain
D) long-term farming has exhausted the ingredients essential to plant growth
3. Glaser made his discovery by __________.
A) studying patches of fertile soils in the central Amazon
B) examining pottery left over by ancient civilizations
C) test-burning patches of trees in the central Amazon
D) radiocarbon-dating ingredients contained in forest soils
4. What does Glaser say about the regrowth of rainforest?
A) They take centuries to regrow after being burnt.
B) They cannot recover unless the vegetation is burnt completely.
C) Their regrowth will be hampered by human habitation.
D) They can recover easily after slash-and-burn farming
5. From the passage it can be inferred that __________.
A) human activities will do grave damage to rainforests
B) Amazon rainforest soils used to be the richest in the world
C) farming is responsible for the destruction of the Amazon rainforests
D) there once existed an urban civilization in the Amazon rainforests

第四篇 2006年12月六级
In a purely biological sense, fear begins with the body's system for reacting to things that can harm us- the so-called fight-or-flight response. "An animal that can't detect danger can't stay alive," says Joseph LeDoux. Like animals, humans evolved with an elaborate mechanism for processing information about potential threats. At its core is a cluster of neurons(神经元) deep in the brain known as the amygdala (扁桃核).
LeDoux studies the way animals and humans respond to threats to understand how we form memories of significant events in our lives. The amygdala receives input from many parts of the brain, including regions responsible for retrieving memories. Using this information, the amygdala appraised a situation- I think this charging dog wants to bite me-and triggers a response by radiating nerve signals throughout the body. These signals produce the familiar signs of distress: trembling, perspiration and fast-moving feet, just to name three.
This fear mechanism is critical to the survival of all animals, but no one can say for sure whether beasts other than humans know they're afraid. That is, as LeDoux says, "if you put that system into a brain that has consciousness, then you get the feeling of fear."
Humans, says Edward M. Hallowell, have the ability to call up images of bad things that happened in the past and to anticipate future events. Combine these higher thought processes with our hardwired danger-detection systems, and you get a near-universal human phenomenon: worry.
That's not necessarily a bad thing, says Hallowell. "When used properly, worry is an incredible device," he says. After all, a little healthy worrying is okay if it leads to constructive action-like having a doctor look at that weird spot on your back.
Hallowell insists, though, that there's a right way to worry. "Never do it alone, get the facts and then make a plan," he says. Most of us have survived a recession, so we're familiar with the belt-tightening strategies needed to survive a slump.
Unfortunately, few of us have much experience dealing with the threat of terrorism, so it's been difficult to get facts about how we should respond. That's why Hallowell believes it was okay for people to indulge some extreme worries last fall by asking doctors for Cipro and buying gas masks.
1. The "so-called fight-or-flight response" (Line2, Para. 1) refers to "________".
A) the biological process in which human beings' sense of self-defense evolves
B) the instinctive fear human beings feel when faced with potential danger
C) the act of evaluating a dangerous situation and making a quick decision
D) the elaborate mechanism in the human brain for retrieving information
2. Form the studies conducted by LcDoux we learn that __________.
A) reactions of humans and animals to dangerous situations are often unpredictable
B) memories of significant events enable people to control fear and distress
C) people's unpleasant memories are derived from their feelings of fear
D) the amygdale plays a vital part in human and animal responses to potential danger
3.Form the passage we know that__________.
A) a little worry will do us good if handled properly
B) a little worry will enable us to survive a recession
C) fear strengthens the human desire to survive danger
D) fear helps people to anticipate certain future events
4. Which of the following is the best way to deal with your worries according to Hallowell?
A) Ask for help-from the people around you.
B) Use the belt-tightening strategies for survival.
C) Seek professional advice and take action.
D) Understand the situation and be fully prepared.
5. In Hallowell's view, people's reaction to the terrorist threat last fall was _________.
A) ridiculous       B) understandable     C) over-cautious    D) sensiblePassage

How Poison Ivy Works
According to the American Academy of Dermatology, an estimated 10 to 50 million people in this country have an allergic reaction to poison ivy each year. Poison ivy is often very difficult to spot. It closely resembles several other common garden plants, and can also blend in with other plants and weeds. But if you come into contact with it, you'll soon know by the itchy, blistery rash that forms on your skin. Poison ivy is a red, itchy rash caused by the plant that bears its name. Many people get it when they are hiking or working in their garden and accidentally come into direct contact with the plant's leaves, roots, or stems. The poison ivy rash often looks like red lines, and sometimes it forms blisters.
1. ______
About 85 percent of people are allergic to the urushiol in poison ivy, according to the American Academy of Dermatology. Only a tiny amount of this chemical -- 1 billionth of a gram -- is enough to cause a rash in many people. Some people may boast that they've been exposed to poison ivy many times and have never gotten the rash, but that doesn't necessarily mean they're not allergic. Sometimes the allergy doesn't emerge until you've been exposed several times, and some people develop a rash after their very first exposure. It may take up to ten days for the rash to emerge the first time.
2. ______
Here are some other ways to identify the poison ivy plant. It generally grows in a cluster of low, weed-like plants or a woody vine which can climb trees or fences. It is most often found in moist areas, such as riverbanks, woods, and pastures. The edges of the leaves are generally smooth or have tiny "teeth". Their color changes based on the season -- reddish in the spring; green in the summer; and yellow, orange, or red in the fall. Its berries are typically white.
3. ______
The body's immune system is normally in the business of protecting us from bacteria, viruses, and other foreign invaders that can make us sick. But when urushiol from the poison ivy plant touches the skin, it instigates an immune response, called dermatitis, to what would otherwise be a harmless substance. Hay fever is another example of this type of response; in the case of hay fever, the immune system overreacts to pollen, or another plant-produced substance.
4. ______
The allergic reaction to poison ivy is known as delayed hypersensitivity. Unlike immediate hypersensitivity, which causes an allergic reaction within minutes of exposure to an antigen, delayed hypersensitivity reactions don't emerge for several hours or even days after the exposure.
5. ______
In the places where your skin has come into contact with poison ivy leaves or urushiol, within one to two days you'll develop a rash, which will usually itch, redden, burn, swell, and form blisters. The rash should go away within a week, but it can last longer. The severity of the reaction often has to do with how much urushiol you've touched. The rash may appear sooner in some parts of the body than in others, but it doesn't spread -- the urushiol simply absorbs into the skin at different rates in different parts of the body. Thicker skin such as the skin on the soles of your feet, is harder to penetrate than thinner skin on your arms and legs.
A Because urushiol is found in all parts of the poison ivy plant -- the leaves, stems, and roots -- it's best to avoid the plant entirely to prevent a rash. The trouble is, poison ivy grows almost everywhere in the United States (with the exception of the Southwest, Alaska, and Hawaii), so geography won't help you. The general rule to identify poison ivy, "leaflets three, let it be," doesn't always apply. Poison ivy usually does grow in groups of three leaves, with a longer middle leaf -- but it can also grow with up to nine leaves in a group.
B Most people don't have a reaction the first time they touch poison ivy, but develop an allergic reaction after repeated exposure. Everyone has a different sensitivity, and therefore a slightly different reaction, to poison ivy. Sensitivity usually decreases with age and with repeated exposures to the plant.
C Here's how the poison ivy response occurs. Urushiol makes its way down through the skin, where it is metabolized, or broken down. Immune cells called T lymphocytes (or T-cells) recognize the urushiol derivatives as a foreign substance, or antigen. They send out inflammatory signals called cytokines, which bring in white blood cells. Under orders from the cytokines, these white blood cells turn into macrophages. The macrophages eat foreign substances, but in doing so they also damage normal tissue, resulting in the skin inflammation that occurs with poison ivy.
D Poison ivy's cousins, poison oak and poison sumac, each have their own unique appearance. Poison oak grows as a shrub (one to six feet tall). It is typically found along the West Coast and in the South, in dry areas such as fields, woodlands, and thickets. Like poison ivy, the leaves of poison oak are usually clustered in groups of three. They tend to be thick, green, and hairy on both sides. Poison sumac mainly grows in moist, swampy areas in the Northeast, Midwest, and along the Mississippi River. It is a woody shrub made up of stems with rows of seven to thirteen smooth-edged leaflets.
E The culprit behind the rash is a chemical in the sap of poison ivy plants called urushiol. Its name comes from the Japanese word "urushi", meaning lacquer. Urushiol is the same substance that triggers an allergic reaction when people touch poison oak and poison sumac plants. Poison ivy, Eastern poison oak, Western poison oak, and poison sumac are all members of the same family -- Anacardiaceae.
F Call your doctor if you experience these more serious reactions:
Pus around the rash (which could indicate an infection).
A rash around your mouth, eyes, or genital area.
A fever above 100 degrees.
A rash that does not heal after a week.
