Everyone can help to save the world

    We are all environmentalists now. We all know about acid rain and the ozone hole. {#blank#}1{#/blank#} As consumers we have the power to make decisions which will contribute to a better world and it is in our power to do what we can to protect the earth.

    {#blank#}2{#/blank#} In this way we have the power to influence retailers (零售商) to sell us these so-called “green” products. Therefore, the supermarkets have understood the message and are now trying to improve their environmental image. They are turning to less wasteful and recyclable packaging. The range of “green” products will continue to expand to meet the growing demand. This message has also reached the manufacturers. {#blank#}3{#/blank#} They have realized that protecting the environment may start as an advertising campaign but in the hands of intelligent people it can become a very profitable business. Besides, we can do more.

    Furthermore, we also know there are other areas where all of us can make a positive contribution to a cleaner, healthier and safer environment. {#blank#}4{#/blank#} There are a number of ways we can do this. For example, we now know how important it is to have our homes well insulated (隔热). We should choose the best energy efficient technology, such as modern light bulbs which can reduce electricity consumption by 80% over the older ones. We must also work hard to reduce the amount of rubbish we produce. We all produce tons of rubbish and waste disposal has become a big problem. As an environmentally-conscious consumer we should buy products which do not have so much packaging. Also, we should try to avoid non-returnable goods at all costs. In Scandinavia and Germany, for example, plastic bottles and cans are now returnable goods.

    In conclusion it is important to emphasize once again the rise of consumer power. We must realize that we are all part of the problem.   {#blank#}5{#/blank#}

A. We can all reduce energy consumption at home and so cut the emissions from power systems.

B. For example, when we walk into a supermarket we can choose to buy environmentally friendly products and reject products which damage our planet.

C. There are some other ways to protect the environment.

D. Companies are developing environmentally friendly products that maintain a high quality and a low price.

E. But what are we doing about these problems?

F. Nevertheless we must also realize that we have the responsibility to be part of the solution.

G. Everybody has the duty to contribute to a cleaner world.

    Imagine walking through an ancient city, then climbing a gate tower to take in a wonderful view of the city and its more than 600-year-old walls. You can hear the city's heartbeat in the air. This is the Ancient City of Pingyao in Shanxi Province, a place that should definitely be on your travel route if you enjoy history or ancient architecture since its origins can be traced back to more than 2,700 years ago.

    Located in the center of Shanxi Province, Pingyao is the hometown of Jin merchants, a group of merchants who actively dominated (支配) a booming commodity market throughout China for more than 500 years, especially during the Ming and Qing dynasties. After the founding of the People's Republic of China in 1949, the city's agriculture and manufacturing industries developed rapidly. Following China's reform and opening-up in the 1980s, Pingyao struggled with the transition from a managed economy to the current market-oriented economy. During this time, the city government sought out new ways to break through this economic bottleneck.

    Finally in the winter of 1997, opportunity came knocking. Through the efforts of the city government, Pingyao earned its place on the UNESCO World Heritage list, which caused the entire world to take notice of the city.

    Since the city's fame has risen, locals in Pingyao have deepened their understanding of the conservation efforts preserving the historical relics in their hometown. Meanwhile the city administration has continued to upgrade itself through a strategy that follows the pillars of “conservation, entrepreneurship, development and protection.”

    Currently, the city is focused on establishing a sustainable industry that will enable it to continue to grow while also protecting its relics and introducing them to the world.

    When I was about 6, I really wanted a new bike! I told my parents my birthday wish but I knew there was little hope, for my family could hardly afford one.

    On my birthday my parents told me they had my gift outside in the backyard. Immediately I rushed out to the yard. There was my bike, but it wasn't the bike that I thought it would be. This one was pink, old and worn with age. I was so disappointed. I thought I hurt my parents because I could see the disappointment on their faces when they noticed my expression. I got on the old bike and rode it, feeling bad because I had made my parents feel that way. So I put on a smile, rode as fast as I could and didn't look back.

    My parents gave me much more than just a rusty (生锈的) old bike. They gave me a life lesson about love. When you give something out of love, it doesn't matter what it actually is. What matters is the love in it. I like to remember this story because giving a gift is not about money or something else. It's about how much love you can feel from it. Do remember, a gift that costs $2 isn't necessarily any less valuable than one that costs $100 or even more.

    "I'm the smartest kid in class." We all want our kids to be self-confident, but unrealistic perception(认知) of their academic abilities, a new study finds, damage a child's relationship with others in the classroom: The more one student feels unrealistically superior(更好的) to another, the less the two students like each other.

Katrin Rentzsch of Bamberg University in Germany first became interested in the effects of such self-perception when she was studying how people became labeled as nerds(书呆子). "I really got interested in the question of whether it's OK to boast(吹嘘) about achievements," she says.

    This line of thinking led her towards something psychologists call "self-enhancement" －when a person feels unrealistically superior to someone else. So Rentzsch and her colleague Michela Schroder-Abe decided to take a closer look at how such self-enhancement affects relationships, so they turned to the eighth-grade classroom, somewhere they could measure differences between actual academic performance, and social popularity. The 358 students came from 20 eighth-grade classes in schools in southeast Germany.

    The researchers asked each student to rate their classmates, in terms of their likability and of their feelings of academic superiority. They then compared those ratings with the students' grades in math, physics, German and English. Importantly, they conducted the analysis at two different social levels: "habitual"－the way people act in general, and "relationship"－the way someone acts around a specific individual.

    In future work, Rentzsch would like to look at these effects on adults, perhaps specifically in team work. She's also interested in self-enhancement beyond academic achievements, for example physical attractiveness. And another question to explore is why students overestimate their academic abilities. Perhaps it is because of too much praise from their parents or teachers.

    The pursuit of longevity has long been on people's minds, prompting an abundance of research on the effects of food and diet on the human lifespan. According to recent research from the UC Irvine Institute, drinking coffee and wine could help you live longer.

    The 90+ Study evaluated more than 1,600 people over the age of 90 for their lifestyle habits and other qualities that might have contributed to their longevity.

    Participants were visited every six months, when they were given various tests. Researchers also collected information about the participants' diets, lifestyles, and medical histories.

    They found out that two of the habits that helped preserve lives the most are drinking alcohol and coffee. "I have no explanation for it," admitted Dr Claudia Kawas, "but I do firmly believe that moderate (适度的) drinking improves longevity." So should we all be drinking more coffee and wine? While that would be great news, the research may not be as definitive as it seems.

    "Most studies about alcohol consumption, including The 90+ Study, are observational, so we can only say that something about drinking is associated with health and longevity," registered dietitian Jennifer Markowitz told The Daily Meal.

    "I'd be curious to see if the coffee and alcohol drinkers shared other important habits or lifestyle factors that might also play into their longevity."

    In other words, it might not be the wine and coffee that's helping people live longer, but the two substances do have some considerable health benefits. "Wine and coffee are packed with antioxidants(抗氧化剂) which are known to protect our bodies from damage caused by free radicals," explained registered dietitian Keri Gans to The Daily Meal. "Research on antioxidants has shown several heath benefits, including the possibility they may lower the risk of type 2 diabetes, improve cognitive function, decrease the risk of dementia, and lower the risk of heart disease."

    Moderate drinking can be beneficial according to other studies—so long as it's moderate.

My love for libraries blossomed when I joined the public library. From the age of 8 I was allowed to walk from my home to the downtown library, housed above the police station. Once the librarian gave me my first membership card, I could enjoy a range of books, which started with Little House in the Big Woods. I was addicted instantly, and this love of libraries and reading would change my life, allowing me to one day create a safe space for high-school kids, too.

By the time I was in high school, I could read the authors that we were studying in class, including Charles Dickens, Mark Twain and Emily Bronte. During the summer months, I got caught up in Gone with the Wind.

When I studied English literature at university, I thought it was time to build my own library. For the next 40 years, I continued to collect books. Until one day, I realized that all my books had become a part of the house, like wallpaper.

Toward the end of my teaching career, I became a teacher-librarian at my old high school, where I had first learned English literature. This position enabled me to regain my love and appreciation for libraries. I had a generous budget for my classes, so I searched for novels that would interest my teenage audience and hopefully spark a love of books. Fantasy, science-fiction, graphic novels -I bought almost any type of books that my students wanted to read. I bought sofas and comfortable chairs, turning the library into a safe public space, for everyone.

In doing so, I realized that the library isn't just a place to do research. They are, in fact, places that offer an opportunity to connect with the past, present and future. All that is required is a tiny bit of curiosity. Libraries are places that should be full of life. They help us adjust to the world, and their doors must be kept open to everyone for free!
