We redheads are well known for our bad tempers. Now it seems there is scientific backing for our particular complaining as well.

Scientists in the United States studied a group of 144 dental patients almost half of whom had red hair. They found that the red-haired group were more sensitive to pain and as a result were twice as likely to avoid visiting the dentist.

Previous research had shown that redheads were more resistant to the effects of local anaesthesia(局部麻醉) than people with other hair colours.

The scientists say that this red-haired sensitivity to pain stems from the actions of a gene called MC1R. This is responsible for the production of melanin which gives skin and hair its colour. In about five percent of white people the gene is mutated(突变) leading to fair skin and red hair.

Researchers say there are some people with the gene in the brain and that this could affect pain sensitivity.

Professor Daniel Sessler from the Cleveland Clinic in the United States is one of the authors of the study. He says the research is a considerable scientific breakthrough.

"Red hair is the first phenotype(表现某一显性特征之生物个体或群体) of anaesthetic requirement in humans. And what I mean by phenotype is an external(外部的) characteristiC．

"So suppuse you are walking down the street and you see someone who's a little older and a little younger - that tells you nothing about their anaesthetic requirement. You see a man and a woman - that tells you nothing about their anaesthetic requirement. But you see a redhead - aha! You know that person is going to require 20 percent more general anaesthesia."

From my own personal experience I would say that there is some merit to this ideA．I have found that I have had to ask dentists for extra anaesthetic in the middle of procedures.

Some dentists argue that a greater sensitivity to pain might actually benefit redheads and drive them to see the dentist more quickly. In my own case I can prove that is definitely not true.

We learn from the text that red- haired group are _______________.

A．easily influenced by the sense of pain and need more anthaethetic reqiurement

B．usually more sensitive to some painful things

C．just well-known for their good temper and strong pain sensitivity

D．good-looking with fair skin and red hair

What do the scientists think this red-haired sensitivity to pain results from?

A．melanin which is responsible for the production which gives skin and hair its colour.

B．the mutated gene leading to fair skin and red hair基因

C．some persons with this gene in the brain

D．an external characteristic of a person.

A．someone’s age and hair

B．someome’s gender and figure

C．someone’s teeth and the skills of the dentist

D．someone’s external charateristic

A．redheads need less anaesthetic in the operation

B．the results of this red-haired sensitivity to pain will be the same

C．the writer is a red-haired person

D．redheads have many benefits of being red-haired

How to make friends with people from a different culture? The rules are as follows:
Appreciate the Person.
Most Americans like to be recognized as individuals as someone special with unique personalities. Therefore, never say, “You’re from America so I want to be your friend.” Also don’t imply that the reason why you approached them is that you wanted someone to practice your English with. That turns people off. Instead try saying,” You seem like a real nice and interesting person and I would like to get to know you better.” This way, they are much more inclined to be friendly because you see them as a three dimensional person and appreciate them for who they are in the inside. And by doing so, you not only learn about Americans and practice your English, but also gain a real friend in the process.
Quit Calling Us Foreigners.
Please avoid calling a foreigner a foreigner especially in his face. The word makes people feel like an outsider, and even unwelcome, suggesting separation and insurmountable differences, widening an already existing gap in the situation. When Americans travel, they rarely say, “ I’m foreign to your place.” They tend to say, “ I’m new in town. I’m new here.” The reason is because new and unfamiliar things can become old and familiar. But can foreign things become native? Aha? You catch my drift.
Just Do It.
Some students like to be told about American culture but are less interested in spending the time and the effort to actually experience it. As Americans always say, “ Get your hands dirty.” You should have first hand and hands on experience, or you’ll never really know anything.
Find that Common Language.
Now I must stress the importance of finding a common language. By that I don’t mean English, Chinese, German, French, etc. I mean finding something you have in common with another person on a spiritual and philosophical level: likes, dislikes, worldviews, ways of thinking , and attitudes toward life. And to start, you must first enhance your knowledge of the particular culture from which your potential new friend comes form.
【小题1】The underlined sentence “ Get your hands dirty” means .

A．get involved	B．start with dirty work
C．talk about American culture	D．don’t wash your hands too often

【小题2】 Americans prefer to make friends with those who .

A．avoid talking about their homeland

B．recognize their personalities

C．obey rules of communicating with friends

D．needn’t practice English while playing together

A．I am longing to make friends with an American.

C．There must be a gap between us in many things.

D．You’ve got a great personality.
