Most of us are already aware of the direct effect we have on our friends and family. But we rarely consider that everything we think, feel, do, or say can spread far beyond the people we know. Conversely(相反地), our friends and family serve as conduits(渠道) for us to be influenced by hundreds or even thousands of other people. In a kind of social chain reaction, we can be deeply affected by events we do not witness that happen to people we do not know. As part of a social network, we go beyond ourselves, for good or ill, and become a part of something much larger.
Our connectedness carries with it fundamental implications(影响) for the way we understand the human condition. Social networks have value precisely because they can help us to achieve what we could not achieve on our own. Yet, social network effects are not always positive. Depression, obesity, financial panic, and violence also spread. Social networks, it turns out, tend to magnify(放大) whatever they are seeded with.
Partly for this reason, social networks are creative. And what these networks create does not belong to any one individual—it is shared by all those in the network. In this way, a social network is like a commonly owned forest: we all stand to benefit from it, but we also must work together to ensure it remains healthy and productive. While social networks are fundamentally and distinctively human, and can be seen everywhere, they should not be taken for granted.
If you are happier or richer or healthier than others, it may have a lot to do with where you happen to be in the network, even if you cannot recognize your own location. And it may have a lot to do with the overall structure of the network, even if you cannot control that structure at all. And in some cases, the process feeds back to the network itself. A person with many friends may become rich and then attract even more friends. This richget-richer dynamic means social networks can dramatically reinforce two different kinds of inequality in our society: situational inequality and positional inequality.
Lawmakers have not yet considered the consequences of positional inequality. Still, understanding the way we are connected is an essential step in creating a more just society and in carrying out public policies affecting everything from public health to the economy. We might be better off vaccinating(接种疫苗) centrally located individuals rather than weak individuals. We might be better off helping interconnected groups of people to avoid criminal behavior rather than preventing or punishing crimes one at a time.
If we want to understand how society works, we need to fill in the missing links between individuals. We need to understand how interconnections and interactions between people give rise to wholly new aspects of human experience that are not present in the individuals themselves. If we do not understand social networks, we cannot hope to fully understand either ourselves or the world we inhabit.

How to become happier is what most of us are after. The things that we think will make us happier—bigger paychecks, nicer homes, slimmer bodies— 1.But practices such as exercising more, socializing, getting enough sleep, and being kind to others do.
2..
Exercise causes hormonal (荷尔蒙的)changes in the body that make us feel good and help interrupt negative thoughts. Anyone who has ever experienced a runner's high will surely agree.
Increase social connections
Reconnecting with a friend can boost happiness, but so can a meaningful encounter with a stranger. 3.. In fact, many studies have found that the more we use social media, the less happy we are.
Get enough shut-eye
4..
Perform acts of kindness
Volunteering to help someone or helping others pay for their bus tickets can make us happy. Giving others a hand takes the focus away from our own worries and problems, which can boost happiness.
These constant practices arc really what's required to boost our happiness. It's like a tire that we put air into. Occasionally it leaks, and we have to put more air into it. It's not one-time thing where we learn it and we're good. 5.. Anyone who adopts and practices the strategies can truly become happier.
A.Burn some calories
B.Prioritize free time
C.don't really matter in our lives
D.But Facebook friends don't count
E.don’t actually add joy to our lives
F.We actually have to put the work in
G.We can set an alarm to signal ourselves to get ready for bed

Most of us spend our lives seeking the natural world. We go fishing, sit in the garden, have a picnic, live in the suburbs or go to the seaside. The most popular leisure activity in Britain is going for a walk. When joggers jog, they don't run the streets. Every one of them tend to go to the park or the river.
But despite this, our children are growing up naturedeprived(剥夺). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.
The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD—attention deficit hyperactivity disorder(多动症). Those whose accommodation had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
ADHD is one of the great problems of modern childhood. One study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.
The life of old people is measurably better when they have access to nature. The increasing concern for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
We need the wild world. It is essential to our wellbeing, our health and our happiness.
1.According to the author, people enjoy ________ to seek nature.
A．jogging on the street
B．sitting in the garden
C．shopping in the supermarket
D．running in the gym
2.From the second paragraph, we can see that ________.
A．adults deprive the children of their rights to approach nature
B．climbing trees will certainly do good to the children
C．children probably spend less time in nature nowadays
D．children tend to be happier as a result of their material satisfaction
3.In what way do people benefit from their contact with nature?
A．Children with ADHD can be cured.
B．A garden nearby improves the quality of old people's life.
C．Problems with crime and violent behaviour will easily be solved.
D．Children's performance at school is greatly improved.
4.What is the main idea of this passage?
A．Access to nature improves our life.
B．Nature treats children for ADHD.
C．Getting close to nature reduces crime.
D．Man can't live without natural areas.

Most of us would like to have glowing skin, especially as we get older. The good news is that you don’t have to wait until summer to catch some sun rays. Scientists have found eating plenty of fruit and vegetables is by far the best way to achieve a healthy, golden glow.
Dr. Ian Stephen said, “Most people think that the best way to improve their skin color is to get a suntan（棕褐色）. But our research shows that eating lots of fruit and vegetables is actually more effective.”
The team first assessed the skin color of people in relation to their diet. Those who ate more fruit and vegetables a day were found to have a more golden, yellow skin color. Those with a healthy glow had a higher presence of carotenoids（类胡萝卜素）, which play a role in the immune system. Carotenoids are commonly found in fruit and vegetables such an yellow and red peppers, spinach, apricots and melons.
The team then studied the relation between skin tone and attractiveness. They used specialist software to operate the skin color on the images of 51 faces to simulate（模拟）more or less carotenoids and suntans. Participants were then asked to adjust the skin color to make the faces look as healthy as possible. Given the choice between skin color enhanced by suntans and skin color enhanced by carotenoids, people preferred the carotenoids skin color.
The study shows that not only do people use skin color to judge how healthy other individuals are, but they are accurate when they make those judgments. While this study focus on Caucasian（白种人的）faces, it suggests this phenomenon may exist across cultures, since similar preferences for skin yellowness are found in an African population.
1.Which statement is TRUE according to the text?
A. Carotenoids are only found in the fruit.
B. Carotenoids are important in the immune system
C. Carotenoids can be improved by catching sun rays.
D. Carotenoids are the only factor that affects the skin color.
2.According to the text, people preferred _______.
A. the yellow skin color
B. the skin color as white as possible
C. the skin color enhanced by suntans
D. the skin color enhanced by carotenoids
3.What can we learn from the text?
A. Young girls should not eat many melons.
B. There’s no need to worry about our skin color.
C. We cannot judge a person from his appearance.
D. Skin color is a clue to judge whether a person is healthy or not.
4.What’s the author’s intention of writing this passage?
A. To show us how to get glowing skin.
B. To persuade us to get suntans every day.
C. To explain different diets in different cultures.
D. To share his experience of improving the skin.

| Anne responded on May 20, 2009 Julie, most of us are never going to achieve the heights you did as the CEO of a company. I just want to say that I was so touched by your transparency (坦诚). I haven’t been attacked publicly ever like you, but I’ve suffered from depression—just recently in fact. It helps a lot to hear personal stories, and it helped to read how you might have handled things differently. |
| Nancy responded on May 21, 2009 Something in Julie drew her to artwork during a very dark time in her journey. And later she stated that it’s beauty that keeps her going. Beauty and creativity can be very powerful in our lives. And it doesn’t surprise me that Julie was drawn to these naturally. Anne, maybe the artistic kinds of activities Julie used will support you well as you move beyond the depressive feelings you’re dealing with. |
| Anne responded on June 4, 2009 Nancy, thanks so much for taking the time to offer some great ideas for using creativity to help with depression. Actually during this time I’ve found that my creative work has been the one thing that’s brought me a lot of joy. |
