In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. “Why is there no blue food? I can’t find blue food—I can’t find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food?”

Well, Carlin pretty much has it right—there is not no blue food, but there’s certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries—like the purple in grapes and red in tomatoes—is found in nature. But it isn’t a hot color for food. People don’t seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue.

Eating, in part, begins with our eyes. Chares Spence—an experimental psychologist from Oxford University—points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching—green fruits can become sweet as they grow up and turn red.

But what about blue? Except blueberries, much of the blue food we see these days is dyed blue artificially. Food producers argue that artificial color doesn’t do much damage to health. A lot of research shows that some physical problems of kids are related to food dyes—while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what?

American researchers found females are the more talkative sex because of a special “l(fā)anguage protein” in the brain.

The study, conducted by neuroscientists (神經(jīng)學(xué)家) and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day — over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.

They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic (超聲波的) range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocal calls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest in them. In contrast, males became less “talkative”.

The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.

“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.

“Our results imply Foxp2 as a component (成分) of the neurobiological basis of sex differences in vocal communication in mammals.”

1.From the second paragraph, we can learn that ________.

A. women always speak more words than men

B. men and male rats have low levels of language protein

C. women and male rats have similar levels of Foxp2

D. McCarthy isn’t the first to find females more talkative

2.The underlined phrase “fussed over” in the third paragraph probably means ________.

A. paid attention toB. related to

C. put pressure onD. counted on

3.The researchers carried out the experiments on rats in order to ________.

A. test which part of the brain is key to language in rats and humans

B. prove the levels of Foxp2 protein in humans and rats are different

C. determine the reason why female rats are more talkative than male rats

D. discover the link between Foxp2 protein and vocal communication

4.Which of the following can be the best title for the passage?

A. Tests on humans and rats

B. Why women are the talkative sex

C. Sex differences in Foxp2 protein

D. Foxp2 protein determines oral ability

Every culture has its own unwritten list of behavior that is acceptable. Every society also has its taboos, or types of behavior that are considered a violation (違反) of good manners.

The word “taboo” comes from the Tongan language and is used in modern English to describe verbal and nonverbal behavior that is forbidden or to be avoided. 1. They tend to be specific to a culture or country, and usually form around a group’s values and beliefs. What is considered acceptable behavior in one country may be a serious taboo in another.

Verbal taboos usually involve topics that people believe are too private to talk about publicly, or relate to one’s manner of speaking. In many cultures, for example, it is considered bad manners to discuss subjects such as sex or religion in public. In some countries, the volume (音量) of one’s voice may annoy people. 2.

3. For example, one of the biggest differences among many Western, Asian, and African cultures is the use of eye contact. In the US, people make eye contact when they talk to others. 4. In many Asian and African cultures, however, children are taught to lower their eyes when talking to their elders, or those of higher rank, as a way to show respect.

Certain gestures made with the hands can have very different meanings depending on the country you are in. Crossing your middle finger over your forefinger is the sign for good luck in many western countries. 5. Also, in some Asian countries, moving your hands a lot while talking, or ‘talking with your hands’, is considered unsuitable.

Behavior that is acceptable and non-offensive in one culture can be highly offensive in another. When visiting a foreign country, be aware of some of the basic differences, as this will help to ensure a more enjoyable trip.

A. Nonverbal taboos usually relate to body language.

B. In Vietnam and Argentina, however, it is a rude gesture.

C. In spite of what some people may think, taboos are not universal.

D. Cancer is a taboo subject and people are frightened to talk openly about it.

E. Learn a country’s customs so that you don’t hurt the local people unconsciously.

F. They might think that someone who is speaking or laughing loudly is rude or aggressive.

G. If a person avoids eye contact, others might think he is being dishonest or unconfident.

When someone has deeply hurt you, it can be very difficult to let go of your anger. But forgiveness is possible — and it can be surprisingly 1. (benefit) to your physical and mental health. So far, research 2. (show) that people who forgive can have more energy, better appetite and better sleep. “People who forgive show 3. (little) anger and more hopefulness,” says Dr. Frederic Luskin, who wrote the book Forgive for Good. “So it can help reduce the tiredness out of the immune system and allow people 4. (feel) more energetic.”

So when someone has hurt you, cool down first. Take a couple of breaths and think of something _5. gives you pleasure: a beautiful scene in nature, or someone you love. Don’t wait for an 6. (apologize). “Many times the person who hurt you may never think of apologizing,” says Dr. Luskin. “They may have wanted to hurt you or they just don’t see things in 7. same way. So if you wait for people to say sorry, you could be waiting a very long time.”

Next keep in mind that forgiveness does not necessarily mean 8. (accept) the action of the person who upsets you. Instead, learn to look for the love, beauty and kindness around you. Finally, try to see things from the other person’s perspective. You may realize 9. he or she was acting out of ignorance. To gain perspective, you may want to write a letter to 10. (you) from that person’s point of view.
