So a project was piloted involving Bangladeshi women in inner city London, most of whom migrated to the UK in the 1960s and 1970s from a rural background. Many of these, women turned to their doctors with common symptoms of anxiety, such as headaches, sleeping difficulties, loss of appetite and lack of energy. They were usually prescribed tranquillizers(镇定剂)or even Vitamin C. Since the underlying causes remained, the women visited their doctors with in creasing frequency and some were referred on to mental-health professionals.
The psychologists wanted to see how normal Western approaches to anxiety problems might work when applied across cultures. However, they found that many things in the standard approach had to be changed. They had to translate many of the usual examples -- they would normally compare learning to relax with learning to drive, for instance, which would not have been culturally appropriate. At first they asked the women to rate, on a scale one to ten, the effect of relaxation on their level of anxiety. They found numbers an odd way of expressing how they were feeling. So psychologists shifted their focus to words rand talked of five stages form. "very good" to "very bad".
As it was a pilot project, there were Shortcomings. Psychologists looked for too little back up and did not collect as much objective data as they might have done with a white group. They fell into the white stereotype of assuming that Bangladeshi women would find the use of various checklists and written records foreign. Perhaps racism has conditioned the professionals to a greater extent than they expected. Psychologists found that using a Western model across cultures has potential. But it needs political, financial and personal commitment.
What does the phrase "color blind" in Paragraph 1 mean？
A．Not liking people from ethnic groups.
B．Giving specialized treatment to ethnic groups.
C．Unable to distinguish certain colors.
D．Not treating ethnic groups differently.

Different Stages of Sleep
A scientist who has spent many years studying sleep was asked this question: "Why do we need sleep？" His answer was."If we do not sleep, we get very sleepy, "No one knows exactly why we sleep．But scientists have learned a lot．From．sleep experiments, scientists have [earned that there are four different stages 0f sleep;
When you first fall asleep, your heart starts to beat more slowly and your breathing slows down．If something wakes you, you might not think that you had been asleep．Some people call this kind of sleep dozing (打盹)．Scientists call it Stage 1 sleep.
Next, if you are no,t awakened, you drift into a deeper sleep．Your pu!se and breathing become even slower than they were during Stage 1 sleep．But you can still be awakened quite easily．If you take a catnap (小睡，打盹), you probably will not get any further than this stage of sleep, which is called Stage 2.
If you sleep longer than about twenty minutes, you go into the third stage of sleep.Your body is very relaxed．It would take a loud noise to wake you up.
You have probably heard of people who walk in their sleep．No one knows what
makes people sleepwalk (梦游)．But a person can sleepwalk only during Stage 4．This is the deepest kind of Sleep．I{ someone wakes you up during Stage 4, you might, feel very confused．It might take you a few minutes to get used to being awake.
After about ten minutes of Stage 4 sleep, you go back to Stage 3 and then to Stage 2.Then, something quite different begins.to happen．Your heartbeat becomes rapid．Your eyelids flutter (跳动), and your eyes move．This stage of sleep is called REM (rapid eye movement) sleep.
Most dreams happen during REM sleep． Scientists who study sleep often make noisesor talk to sleeping people in the REM stage．They are trying to find out what effects noises can have on dreams． As sleep research continues, scientists might also learn what causes dreams and how dreams might be helpful to people.

The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for new users and market sections. Did you know, for example, that the backpacks that so many students carry today were originally designed for the military？
Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.
Another product extension strategy is called product modification. It involves changing product quality, features, or style. to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to recapture world markets. Note, also, how auto manufacturers once changed styles dramatically from year to year to keep demand from falling.
第26题：According to the passage, when people grow fond of one particular brand of a product, its sales will ________.
A) decrease gradually
B) remain at the same level
C) become unstable
D) improve enormously

Problems of Anxiety
Training as mental-health professionals is supposed to be "color blind". That sounds fine but in practice it means that people from black and ethnic groups get an unfair treatment because their particular problems are seldom acknowledged.

Why do we Dream？
For centuries, we've tried to figure out just why our brains play these nightly shows for us. Early civilizations thought dream worlds were real, physical worlds that they could enter only from their dream state. Researchers continue to toss around many theories about dreaming. Those theories essentially fall into two categories:
The idea that dreams are only physiological stimulations
The idea that dreams are psychologically necessary
Physiological theories are based on the idea that we dream in order to exercise various neural connections that some researchers believe affect certain types of learning. Psychological theories are based on the idea that dreaming allows us to sort through problems or events of the day or things that are requiring a lot of our attention. Some of these theorists think dreams might be prophetic. Many researchers and scientists also believe that perhaps it is a combination of the two theories.
Dreaming and the Brain
When we sleep, we go through five sleep stages. The first stage is a very light sleep from which it is easy to wake up. The second stage moves into a slightly deeper sleep, and stages three and four represent our deepest sleep. Our brain activity throughout these stages is gradually slowing down so that by deep sleep, we experience nothing but delta brain waves--the slowest brain waves. About 90 minutes after we go to sleep and after the fourth sleep stage, we begin REM sleep.
Rapid eye movement(REM)was discovered in 1953 by University of Chicago researchers Eugene Aserinsky, a graduate student in physiology, and Nathaniel Kleitman, Ph. D. , chair of physiology. REM sleep is primarily characterized by movements of the eyes and is the fifth stage of sleep.
How to Improve Your Dream Recall
It is said that five minutes after the end of a dream, we have forgotten 50 percent of the dream's content. Ten minutes later, we've forgotten 90 percent of its content. Why is that？ We don't forget our daily actions that quickly. The fact that they are so hard to remember makes their importance seem less.
There are many resources both on the Web and in print that will give you tips on how to improve your recall of dreams. Those who believe we have a lot to learn about ourselves from our dreams are big proponents of dream journals. Here are some steps you can take to increase your dream recall:
When you go to bed, tell yourself you will remember your dreams.
Set your alarm to go off every hour and a half so you'll wake up around the times that you leave REM sleep--when you're most likely to remember your dreams.(Or, drink a lot of water before you go to bed to ensure you have to wake up at least once in the middle of the night!)
Keep a pad and pencil next to your bed.
Try to wake up slowly to remain within the "mood" of your last dream.
Common Dream Themes and Their Interpretations
Being naked in public
Most of us have had the dream at some point that we're at school, work or some social event, and we suddenly realize we forgot to put on clothes! Experts say this means:
We're trying to hide something(and without clothes we have a hard time doing that).
We're not prepared for something, like a presenta
