As a Chinese saying goes, "Taste is actually a memory of childhood". Local specialty food may not be popular among all people, but it offers outsiders a glimpse of local culture and history.

    Gongcheng "oil tea" is such a kind of food that would be considered "weird" by many first-time visitors to the remote county in the north of the Guangxi Zhuang Autonomous Region. Many people dislike its bitter and astringent(涩的) flavor when they take a sip.

    "It felt like drinking Chinese herbal medicine. I never expected that I would gradually accept it afterwards, and even become addicted to it," said a traveler surnamed Zhang who comes from Shijiazhuang in northern China's Hebei province.

    Langshan village is said to be the birthplace of Gongcheng "oil tea" whose ideal ingredients are green tea and fermented tea. The village has preserved well its buildings and roads dating back to late Qing Dynasty (1644-1911), as well as its traditional way of making the special tea.

    Lin Fengyou, 60, introduced the cooking process. She looks younger than her age, and attributes this to the benefits of drinking "oil tea" throughout the year.

    The first procedure is to use a wooden hammer to pound the tea while heating it in an iron pot, and then add edible oil and boiled water afterwards. She filters off the solid residues(余渣), and pours the glue-like green tea soup into bowls. Then, she adds salt, caraway seed, green onion, dried rice, fried groundnuts, sliced taro and fried beans.

    The taste of the "oil tea" is a mixture of the distinctive flavors of all its ingredients. Local people usually eat it together with glutinous rice(糯米) balls, rice dumplings and glutinous rice cake.

    The villagers consume "oil tea" three times a day. The tea soup is a healthy and refreshing food. "The tea soup to us is coffee to Westerners", said Lin. "But it is tastier."

    To develop one's taste in English，the most effective way is to read English books extensively. However, one may be at a loss to choose the appropriate books，especially as a beginner.I would like to share some of my experience.

    My first English novel was Jane Austen's Pride and Prejudice，recommended by many English teachers and professors as an ideal book for English learners. But I had great difficulty in understanding the novel，let alone enjoying it. It's not the vocabulary that troubled me，but rather the way Austen constructs sentences，and her way of thinking，which seemed too remote to me at that time. My fading enthusiasm was much recovered after reading Hemingway's novel Farewell to Arms. I particularly liked his brief and lively style. So my first suggestion is，as a beginner, you'd better choose contemporary novels instead of classical ones.

    However，reading novels is not the only way to improve your English. English essays can at once inform you，entertain you, and improve your taste in English. The best example is Bertrand Russell's work. Its language is plain, yet you cannot help feeling the elegance and the unique sense of humor. His simple language enables his philosophy(哲理) within the reach of ordinary people. Here comes my second suggestion—essays are indispensable.

    Never follow other's opinions blindly，however famous or influential the person might be. As a saying goes，one man's meat is another man's poison. With that in mind，we are sure to find out our favorite writers through reading and develop our fine taste in English.

    One of the most efficient ways to achieve peace and speed up economies (经济) is to provide girls with better education and more rights. Today, girls' lack of access (进入) to basic education is getting more serious when it comes to the use of digital (数码的) technology, leaving them far behind boys. And because the world is even more digital, those who lack basic internet skills will find it increasingly more difficult to take part in the formal economy, to get a quality education, and to have their voices heard.

    Since 2013 the global gender gap (性别差异) in male and female access to the Internet has actually increased from 11 to 12 percent. Worse yet, women and girls living in the poorest countries are 31 percent less likely than men and boys to have access to the Internet. In developing countries, some 200 million fewer women than men own a mobile phone, the most common means of internet access there. This digital divide is increasing, and should it continue at the present pace, it is projected that over 75 percent of women and girls will lack internet access and digital skills.

    There are many causes of the digital gender gap. They include girls' exclusion (排斥) from basic education, from specific technology education and high costs of mobile phones and internet access.

    Indeed, one of the so-called reasons why girls may be discouraged from learning how to access and use digital technology is also a groundless one: that girls are simply not good at using technology.

    Without the help of the government, most of the benefits of technological change will be enjoyed only by men, exacerbating gender inequality.

    World leaders from nearly 200 countries have signed an important historic agreement to fight global climate change. The agreement came after two weeks of talks between the leaders at the 21st Conference in Paris, France.

    As part of the Paris agreement, countries said they would cut down on pollution However, according to the terms of the deal, countries that don't do this will not be punished, or fined. Instead，the document is meant to show that governments around the world take climate change seriously and are willing to work together to fight global warming.

    World leaders have met many times to discuss climate change. But, the 21st Conference of Parties, or COP21, which began on November 30 in Paris, was the first time they agreed on a global, legal pact (协定).

    Before the conference, each nation was asked to create plans on how to reach the shared goal. The pact that was signed allows countries to decide the best way to cut down their gas pollution. No matter how they decide to go green, each country must report honestly on all of their efforts. Every five years, nations must look at the work they've done and submit new plans on how they will improve over the next five years.

    In the pact, the countries pledge（承诺）to limit the amount of greenhouse gases emitted（排放） by human activity to the levels that trees，soil and oceans can absorb naturally. It urges countries to spend trillions of dollars on creating new energy sources, like solar and wind power. It also requires countries to raise at least $ 100 billion each year to help developing countries.

    However, critics of the pact say it is not detailed enough, and doesn't include specifics about how the plan will be enforced and how improvements will be measured. The pact does include one large, specific goal: how countries will aim to keep global temperatures from rising more than 3.60℉(20℃) by 2100.

    Nonetheless，the agreement is considered by many world leaders to be a major victory. The U. N. has been working more than two decades to convince governments to work together to reduce man-made emissions.

    “History will remember this day,” U. N. Secretary General Ban Ki-moon said. “The Paris agreement on climate change is a monumental success for the planet and its people.”

    Harvard University in the United States has been ranked as the university with the best “reputation” in the world.

    The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say, the list measures how universities are regarded, rather than how they actually performed.

    “A subjective, word-of-mouth (口碑的) quality such as “reputation” has genuine economic value for universities,” said Simon Marginson, professor of higher education at the University of Melbourne in Australia.

    “Reputation is not just an impression, though it might not be as reliable as performance by objective indicators (客观指标),” said Prof Marginson.

    Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which dominate this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth.

    “For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness,” said the president of Cambridge University's students' union, Rahul Mansigani.

    “Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge,” he said.
