6.Biologists believe that love is fundamentally a biological rather than a cultural construct,because the capacity for love is found in all human cultures and similar behavior is found in some other animals.In humans the purpose of all the desire is to focus attention on the raising of offspring.Children demand an unusual amount of parenting,and two parents are better than one.Love is a signal that both partners are committed,and makes it more likely that this commitment will continue as long as necessary for children to reach independence.But what does science have to say about the notion of love at first sight?
In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love.Researchers have shown that when a person falls in love,a dozen different part of brain work together to release chemicals that trigger feelings of euphoria,bonding and excitement.It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.
Passionate love is rooted in the reward circuitry of the brain-the same area that is active when humans feel a rush from cocaine.In fact,the desire,motivations and withdrawals involved in love have a great deal in common with addiction.Its most intense forms tend to be associated with the early stages of a relationship,which then give way to a calmer attachment form of love one feels with a long term partner.
What all this means is that one special person can become chemically rewarding to the brain of another.Love at first sight,then,is only possible if the mechanism for generating long-term attachment can be triggered quickly.There are signs that it can be.One line of evidence is that people are able to decide within a second how attractive they find another person.This decision appears to be related to facial attractiveness,although men may favor women with waist-to-hip ratio of 0.7,no matter what their overall weight is.(This ratio may indicate a woman's reproductive health.)
Another piece of evidence comes from work by a psychologist at Ben-Gurion University,who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight.In other words,in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond.It is also clear that some couples need to form their bonds over a longer period,and popular culture tells many tales of friends who become lovers.
One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly,such as compassion,intellect or a good sense of humor,then it would be hard to form a relationship on the basis of love at first sight.Those more concerned with visual appearances,though,might find this easier.So it appears that love at first sight exists,but is not a very common basis for long-term relationships.
62.When a person falls in love,C.
A.he feels as if he were addicted to cocaine.
B.he will be committed to the beloved as long as necessary.
C.he will experience complex feelings brought on by different regions of his brain.
D.he will experience a calmer attachment form of love before he feels the extreme love.
63.We can infer from the passage thatD.
A.pair-bonding love comes from a long stable friendship.
B.the mechanism for creating long-term attachment ensures love at first sight
C.it is impossible for those ordinary-looking people to fall in love at first sight.
D.men may be attracted by a girl whose figure suggests her admirable reproductive capacity.
64.The underlined word"traits"in the last paragraph probably meansC.
A.characteristics
B.something typical in your temper
C.particular quantities in your personality
D.attitudes that show your moral standards
65.Which of the following may be the best title of the passage?B
A.The stages of passionate love
B.The science of love at first sight
C.The biological construct of pair-bonding
D.The mechanism for generating long-term love.

11.A recent finding has showed that blue-eyed people have already been living in Europe for at least 7,000years.
A man who lived on the Iberian Peninsula before Europeans became farmers probably had blue eyes but dark hair and skin,according to scientists who have arranged his DNA in order.This surprising combination of eye,hair and skin coloring may not have been unusual during his lifetime,but it is no longer seen among modem Europeans,reported by the journal Nature.
The man,a Neolithic hunter-gatherer known to scientists as La BranaⅠ,is of great interest to scientists because he offers a brief introduction to what was in Europeans'DNA before agriculture spread through the continent.Experts have theorized that certain genetic feature spread quickly among humans after they adopted the farming lifestyle.La BranaⅠshows that at least some of their predictions were correct.
The man's skeleton,along with that of a male companion,was discovered in 2006in a cave in what is now northeastern Spain.The site,known as La Brana-Arintero,sits about 5,000feet above sea level,and the cave provided a cold,refrigerator-like environment that preserved his DNA.
In the lab,scientists were able to remove enough DNA from a single tooth to reconstruct La BranaⅠ's entire genome (基因组).They compared it to the DNA of other ancient Europeans(including Otzi,the 5,300-year-old mummy found in an Alpine glacier) and determined that he was a closer match with hunter-gatherers than with farmers.
When it came to genes that would influence La BranaⅠ's appearance,the researchers found that their 7,000-year-old subject had versions of two skin pigment(色素) genes that are either very rare or nonexistent among Europeans today.Then they looked at other places in the genome that influence pigmentation(色素沉着)and found a mix of ancient and modern gene variants(变种).Taken together,La BranaⅠ's DNA"is likely to have resulted in dark skin pigmentation and dark or brown hair,"they wrote.
However,his DNA indicates that his eyes were most likely blue,the scientists found.This suggests that gene variants for light-colored eyes and skin did not spread together,they wrote,adding that La BranaⅠ's combination"of dark skin and non-brown eyes is unique and no longer present in contemporary European populations."Today,a blue-eyed person would typically have fair skin.To get some idea of whether La BranaⅠ's coloring was unusual for his day,the researchers will try to arrange in order the DNA of his companion,who has been named La BranaⅡ.
32.Scientists have carried out the research into La BranaⅠbecause they wanted to know
C.
A.today's Europeans'DNA             
B.the ancient agriculture in Europe.
C.European hunter-gatherers'DNA.
D.the correctness of some of their predictions
33.La BranaⅠ's skeleton was best preserved mainly because ofB.
A.the height of the cave                
B.the cold condition in the cave
C.the location of the cave              
D.the wet condition in the cave
34.Which of the following statements is TRUE?B
A.La BranaⅠ's gene variants spread together.
B.La BranaⅠ's DNA influences his appearance.
C.Today's blue-eyed person may typically have rough rather than fair skin.
D.La BranaⅠ's gene is completely different from the contemporary Europeans'.
35.The last paragraph suggests thatC.
A.La BranaⅡhas the same genome with La BranaⅠ.
B.Blue-eyed people were common in Europe 7,000years ago.
C.It's not certain that La Brana's appearance was common at that time.
D.BranaⅠ's combination of dark skin and non-brown is popular in contemporary Europeans.
1.Here are some tips for applying to US colleges.
Why are American universities so expensive?
First of all,I'll say that American education is expensive for Americans but you're getting a high-quality education from some of the best professors in the world with some of the best resources and facilities in the world.American universities have state-of-the-art laboratories,computers,research systems,classrooms and all that is expensive.And also at many U.S.universities,you're learning from leading researchers and people who are at the top of the line in their field so it's also expensive for universities to have those people as professors.So,you're paying for a quality product-that's why it's very expensive.
What kind of financial aid is available?
It really depends on the university what kind of financial aid is available.There are a lot of opportunities out there for international students.There are some universities that have merit-based scholarships.Many have scholarships in general for international students.There are athletic scholarships,scholarships based on a specific talent.
Are school rankings important?
I know that rankings matter to a lot of parents and students worldwide,but here in the U.S.we pay very little attention to rankings.The rankings that are produced are actually the opinion of several different magazines.The official government doesn't have a universal ranking system.With that said,we know that for many families abroad and outside the United States,rankings are very important.So as a university,we try to make that information available so that students can see our rankings.
How can I prepare for the visa interview?
As long as you are a genuine student,it's likely that you will receive your visa.When you go for the interview they're looking for generally three things.
One,of course,when you go into that visa interview,you should really know things about the university that you're going to,why you're going there,why you want to study,what you want to study-that's how you show that you're a genuine student.
The second thing that they're looking for is to be sure that you have the finances to cover your educational program.You'll have to submit the same bank documentation you used in order to get your I-20to the U.S.Embassy as part of your interview to prove that you are able to pay for your education in the U.S.
The next thing that they're mainly looking for is to be sure that you're a legitimate student and that you're not looking to move to the United States,that you have a reason to return to your home country,prospective employment.

46.The passage mainly talks about some tips for applying to US colleges exceptA.
A.high-quality education 
B.financial aid
C.school rankings                                                              
D.visa interview
47.Why are American universities so expensiveB?
A.Because there are so many international students aims at applying to US colleges.
B.Because Americans are getting a high-quality education.
C.Because state-of-the-art laboratories,computers,research systems,classrooms are
all expensive.
D.Because leading researchers and top professors are expensive for universities
48.What kind of financial aid is availableD?
A.merit-based scholarships
B.athletic scholarships
C.scholarships based on a specific talent.
D.It depends on the university
49.Why do American universities try to make the school rankings availableC?
A.Rankings matter to a lot of parents and students in the U.S.
B.They want to let students get whole information so that they can see their rankings clear.
C.Many families abroad and outside the United States pay great attention to school rankings
D.The rankings that are produced are actually the opinion of several different magazines.
50.Which of the following statement is trueD?
A.American universities have the best professors in the world.
B.Universities have merit-based scholarships for every international student.
C.Rankings are very important in U.S.,so we try to make that information available
D.You'll have to submit the same bank documentation you used in order to get your proof
