Dear SJ,

    Losing a best friend is never easy.

    Your problem, is not just that you miss your best friend, it is that you feel empty and lost without her friendship.

    It takes time to get over a lost, and during that time, your mind is getting used to a new way of being. This is usually a good thing, even if it feels like a bad thing.

    Now that you are on your own, you are being forced to learn to be by yourself and to rely upon your own inner voice for guidance. I am sure that this feels strange for you, but if you can hang on for a bit longer, it may work to your advantage.

    Best friends are cool, but it is important to know the difference between missing someone and being too independent upon them.

    At your age, girls do tend to stick together and having a good boyfriend may not yet be the better choice. Your friend is leaving you, her best friend, for a boyfriend. Boyfriends are completely different from best friends. The distinction is that boyfriends come and go, while girl friends often stay in your life throughout high school, and even afterwards. It is a completely different sort of bond.

    I suggest that you take advantage of this period in your life to expand your horizons. Enjoy the freedom of having no best friend for a while, and hang with the group. By the time your former best friend breaks up with her boyfriend, you will be in a completely different place, a far better place.

    And, by the way, next time you feel empty and lost, try to write about it in a diary. In several months, you will look back and read it with curiosity about yourself. “Who was I then, and what could I have been thinking?”

    The latest Chinese “god song”(an Internet term to describe pop songs that spread virally through the Internet(像病毒一样传播开来) is still making debates(争论) between those who view it as a milestone for Chinese pop music going global and those who regard it as a bad image of China.

    Last week, Little Apple, written and performed by the Chopsticks Brothers, won the AMA International Song Award and the duo performed the song at the 2014 American Music Awards in Los Angeles. Another Chinese pop singer, Zhang Jie, won the International Artist Award.

    But while fans of these singers are thinking highly of the awards(奖) and the performance by the Chopsticks Brothers at the AMA celebration, there are others who are less excited. They have questioned the value of the awards and what effect it will have on Chinese culture's “going abroad”, saying it may leave foreign audiences with a poor impression(印象) of Chinese pop music, and even Chinese culture.

    The Little Apple phenomenon, both home and abroad, can be more easily understood and judged if we look at it from a business view rather than a cultural view. The professional promoters behind the duo have developed a clear strategy(策略) to promote the duo and their works, not just this particular song. Little Apple was originally released(发行) to promote the duo's film Old Boys: The Way of the Dragon.

    From the very beginning a marketing strategy was used to promote(提升) the song, which immediately went viral on the Internet due to its repetitive rhythm(重复的韵律)，easy-to-remember lyrics(歌词), simple and funny dance and, most importantly, grass roots (草根) nature. The video accumulated(积攒) more than 1 billion bits on China's major video websites.

    Although the song was generally disliked by music professionals who criticized(批评) it as “musical junk food”, Little Apple's popularity nationally paved the way(为…铺平道路) for promoting the duo internationally.

    In a historic moment on June 26, the US Supreme Court ruled that same-sex marriage is a legal right across all 50 states. The Supreme Court justices ruled states cannot deny gay men and women the same marriage rights. The decision means the 13 states with bans on same-sex marriage are no longer able to enforce them.

    Same-sex couples “ask for equal dignity in the eyes of the law”. Justice Anthony Kennedy wrote in the majority opinion: “The Constitution grants them that right.”

    The decision came after decades of litigation（诉讼） and activism. It set off celebrations across the US. In affected states including Georgia, Michigan, Ohio and Texas, same-sex couples rushed to wed, while officials in Mississippi and Louisiana said marriages had to wait until procedural issues were addressed, reported the BBC.

    According to “The New York Times”, the ruling came against the backdrop of fast-moving changes in public opinion in the US, with polls indicating that most Americans now approve of same-sex marriage.

    US President Barack Obama welcomed the ruling, saying it “affirms what millions of Americans already believe in their hearts.” “Today,” he said in a press release, “we can say, in no uncertain terms, that we have made our union a little more perfect.”

Another win.

    This was the second time the Supreme Court took up same-sex marriage, according to an article in “Business Insider”. The first time, in June 2013, the court made a decision that allowed the US federal government to recognize same-sex marriages in states where they were already legal.

    But at that time, the Supreme Court declined to rule on the broader question about gay marriage: Is there a constitutional（宪法的） right to same-sex marriage? The June 26 ruling gave a positive answer to that question.

Justice Kennedy wrote in the majority opinion that the Constitution should evolve with societal changes.

    “The nature of injustice is that we may not always see it in our own times,” he wrote. “The generations that wrote and ratified the “Bill of Rights” and the “Fourteenth Amendment（修正案）” did not exactly know the extent of freedom in all of its dimensions, and so they hoped the future generations can protect the right of all persons to enjoy liberty as we learn its meaning.”

    The Fourteenth Amendment addresses citizenship rights and equal protection of the law. In the June 26 ruling, the Supreme Court declared that the equal protection clause of the amendment requires marriage rights be extended to same-sex couples, too.

    Reuel Tolkien (1892 ~ 1973), the British linguist, writer. He created a fantasy novel “The Lord of the Rings”, the well-known trilogy (三部曲).

    Tolkien was born in Bloemfontein, South Africa. When he was 4 years old, his father died and his family moved back to England. Tolkien graduated from Oxford University when he was 23 years old, and participated in the First World War. During the war, Tolkien suffered from “trench fever” and stayed in the hospital until the end of World War I. It was the days in the hospital that he began his writing career first.

    After the war, Tolkien became a linguist. He was an edition of the “New English Dictionary” of 1918 ~ 1920. However, he was more researching to Anglo-Saxon language which makes his extensive contacts in Britain and the Nordic spread all over the folklore and mythology.

    In 1937, Tolkien completed his first work “The Hobbit”. Although this was a fairy tale, it was also suitable for adults to read. Because of good sales, publishers (Allen & Unwin) convinced Tolkien to write its sequel. This encouraged Tolkien to complete his most famous works the epic (史诗) trilogy “The Lord of the Rings”. The works of writing went on for almost a year with the support from his good friend Lewis.

    At the beginning “The Lord of the Rings” was similar works for children, but after that writing style quickly became serious and dark. “The Lord of the Rings” was one of the most popular literary works in the 20th century in terms of sales and readers' evaluation. Tolkien's influence is important, for the success of “TheLord of the Rings” makes the fantasy novels of this literature genre (体裁) developed rapidly.

    Healthy, convenient and increasingly popular over the past few years, sushi has become as common a dish in the UK as in India or China. It's a popular lunch-choice for city-workers all over the country and you're never far from a restaurant or supermarket selling the traditional Japanese dish. But it turns out sushi may not be as healthy a choice as we thought — leading biologists have warned that it is in fact harming both the environment and our health.

    The UK sushi market is worth £69 million a year, but because we're eating so much of it, the tuna (金枪鱼) population in the oceans is dwindling. According to Professor Daniel Pauly and Dr Dirk Zeller, the leaders of British Columbia, Bluefin and yellowfin tuna populations have reached dangerous levels.

    Bluefin tuna is often served in high-end, excellent sushi restaurants, while yellowfin is more common in high-street sushi bars and supermarkets. Increasing global need means tuna populations are being overfished. Most of the UK's sushi comes from the Indian Ocean, but according to Professor Pauly we now only have 2-3 percent of what we had 200 years ago.

    Professor Pauly and Dr Zeller believe it is our love of healthy tuna that's causing the problems in our oceans. The fish is popular not just for its taste but for its health benefits. But while sushi has earned popularity for being low in calories and high in nutrients (营养物), we may have overestimated (高估) its health value.

    In advance of a lecture at the Zoological Society of London lately, Professor Pauly said he believes most high-street restaurants serve sushi that contains plastic microbeads (塑料微珠). “Microbeads are poison pills which take in all the pollutants and they are eaten by little fish which are then eaten by tuna.”

    So what should we eat instead? Dr Zeller and Professor Pauly are asking the public to step away from sushi and eat more fish like anchovies (凤尾鱼) — less attractive, but better for your health and the environment.

    Hundreds of villages in rural India are using clean energy powered by the sun.

    This month, 61 households in the village of Baripatha in eastern India were given two solar lamps. Villagers had been using kerosene lamps at night. Kerosene produces pollution and can lead to fires.

    The Indian government wants to increase the use of solar energy by 500 percent in the next seven years. If it is to reach that goal, 100 gigawatts of power must come from solar by 2022.Now,just 4 gigawatts of power created in the country come from the sun.

    Officials say they want to slow the amount of greenhouse gas emissions. India is now the third largest producer of this gas. The gas contributes to climate change.

    Arunabha Ghosh is the head of the Council on Energy, Environment and Water, a policy research group in New Delhi.

    He says“in terms of the share of electricity capacity that Germany achieved through renewables, that transition took about 22 years for Germany. In India's case, which is a much poorer economy, India is planning to have a similar shift towards renewable energy and non-fossil energy” within 15 years.

    India's goal may be helped by the decreased cost of developing solar energy. The government says it wants investors to spend $ 100 billion over seven years in solar power. It is reducing taxes for some solar-related investments. And it is permitting non-Indians to invest.

    This week, Germany said it would spend more than $ 2 billion on solar projects in India. SunEdison, an American renewable-energy company, says it wants to invest $ 15 billion. SoftBank, a Japanese company, has announced it will partner with companies in India and China to spend up to $20 billion on solar energy projects. Trina Solar, a Chinese company, plans to spend $500 million to make solar panels.

    Some people in India are worried that there is not enough land for some of these projects. Many of the projects need large plots of land.

    Inderpreet Wadhwa created a company called Azure Power. It was one of the earliest investors in solar projects. He said most of them are being built in dry areas of the country, on land that cannot be farmed.
