We each have a unique genetic (基因的，遗传的) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion combinations of DNA which come from the random mixing of your parents’ genes. Except for identical twins (同卵双胞胎), no one has the same combination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make.
But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.
Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.
Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.
We could ask, “Are our lives determined by our genes or our upbringing?” Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.

When asked about happiness, we usually think of someth.ng extraordinary, an absolute delight, which seems to get rarer the older we get.
For kids, happiness has a magical quality. Their delight at winning a race or getting a new bike is unreserved (毫无掩饰的).
In the teenage years the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.
In adulthood the things that bring deep joy—love, marriage, birth—also bring responsibility and the risk of loss. For adults, happiness is complicated(复杂的).
My definition of happiness is "the capacity for enjoyment". The more we can enjoy what we have, the happier we are. It's easy to overlook the pleasure we get from the company of friends, the freedom to live where we please, and even good health.
I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunch-box and had the house to myself. Then I spent an uninterrupted morning writing, which 1 love. When the kids and my husband came home, 1 enjoyed their noise after the quiet of the day.
Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children, had much of either. She did have a network of close friends and family, and maybe this is what satisfied her.
We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our "right" to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.
Happiness isn't about what happens to us―it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have, but enjoying what we do possess.
51. As people grow older, they ______.
A. feel it harder to experience happiness
B. associate their happiness less with others
C. will take fewer risks in pursuing happiness
D. tend to believe responsibility means happiness
53. What can we learn about the author from Paragraphs 5 and 6?
A. She cans little about ha own health
B. She enjoys the freedom of trawling
C. She is easily pleased by things in daily life.
D. She prefers getting pleasure from housework
53. What can be inferred from Paragraph 7?
A. Psychologists think satisfying work is key to happiness
B. Psychologists* opinion is well proved by Grandma's case.
C. Grandma often found time for social gatherings
D. Grandma's happiness came from modest expectations of life,
54. People who equal happiness with wealth and success
A. consider pressure something blocking their way
B. stress their right to happiness too much
C. arc at a loss to make correct choices
D. arc more likely to be happy
55. What can be concluded from the passage?
A. Happiness lies between the positive and the negative.
B. Each nun is the master of his own fate
C. Success leads to happiness.
D. Hippy is he who is content.

When scientists set out to explore the roots of human laughter, some apes（类人猿） were just tickled（胳肢）to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution（进化）.
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate（灵长类动物） roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.
69. Why did the scientists analyze the laughter made by tickling human babies and apes?
A. To try to discover if they can make characteristic sounds.
B. To see if they interested in playing.
C. To find out if the laughter of apes and humans is related.
D. To find out the differences between humans and apes.
70. Based on Paragraph 3 we can know that researchers measured the features in the sound to ________.
A. find out ape sounds that hadn’t been realized before
B. find out relations among primates’ laughter
C. see what a family tree from each species looks like
D. make a report online in the journal Current Biology
71. What can be inferred from the last paragraph?
A. Panksepp spoke highly of the new research.
B. Rat laughter is likely to be related to ape laughter.
C. Robert Provine provided some new clues for the researchers.
D. Humans don’t enjoy listening to ape laughter.
72. What would be the best title for the passage?
A. Ape study explores evolution of laughter.
B. Apes like to laugh when being tickled.
C. Human laughter and ape laughter are different.
D. Laughter: A Scientific Investigation.

Forests in the northern half of the globe could be growing faster now than they were 200 years ago as a result of climate change, according to a study of trees in eastern America. The trees appear to have faster growth rates due to longer growing seasons and higher concentrations (浓度) of carbon dioxide in the ___41___.
Geoffrey Parker, a scientist at the Smithsonian Environmental Research Centre in Edgewater. Maryland, said that the increase ha the rate of growth was unexpected and might be ___42___ to the higher temperatures and longer growing seasons documented in the region. The growth may also be influenced by the significant ___43___ in atmospheric CO2, he said.
"We made a list of reasons these forests could be growing faster and then excluded half of them," Dr. Parker said. Their study suggests that northern forests may become increasingly important in ___44___ the influence of man-made CO2 on the climate.
Dr. Parker and his colleagues have ___45___ out a detailed record of the trees on a(n) ___46___ basis since 1987. They calculated that due to the global warming the forest is producing ___47___ tons of wood each year.
The scientists ___48___ the land with trees at different stages of growth and found that both young and old trees were showing increased growth rate. More than 90 per cent of the tree groups had grown by between two and four times faster than the scientists had ___49___ from estimates of the long-term rates of growth.
