To understand how Americans think about things, it is necessary to understand "the point". Americans mention it often: "Let's get right to the point." They will say, "My point is…" "What's the point of all this?"

    The "point" is the idea or piece of information that Americans suppose is, or should be, at the center of people's thinking, writings, and spoken comments. Speakers and writers are supposed to "make their points clear", meaning that they are supposed to say or write clearly the idea or piece of information they wish to express.

    People from many other cultures have different ideas about the point. Africans traditionally tell stories that express the thoughts they have in mind, rather than stating the point clearly. Japanese traditionally speak indirectly, leaving the listener to figure out what the point is. Thus, while an American might say to a friend, "I don't think that coat goes very well with the rest of your outfit," a Japanese might say, "Maybe another coat would look even better than the one you have on." Americans value a person who "gets right to the point". Japanese are likely to consider such a person insensitive if not rude.

    The Chinese and Japanese languages are characterized by vagueness and ambiguity. The precision and directness Americans associate with "the point" cannot be achieved, at least not with any grace, in Chinese and Japanese. Speakers of those languages thus have to learn a new way of reasoning and expressing their ideas if they are going to communicate satisfactorily with Americans.

    Whether you are young or young at heart, it is never too late to change, or take in some new and better practices into your daily life. Here are some wise lessons that I wish I knew when I was younger.

    I used to be worried about what others thought of me. Finally, I changed. Remember that if you're wasting too much time looking for respect(尊重) from others, then you will not have time to finish all you desire(期望).Everyone has an opinion, but in fact others' opinions about you are based more on their history and perceptions(观念) than anything you're actually doing. So depend on your own assessment(评估) of you rather than others'.

    Enjoy every moment of today. Don't wait to do or enjoy anything. Don't tell yourself you will do it tomorrow. If it is important to you, then do it today. Pay attention to what is happening now, the task at hand and all the choices you make today, big and small. Our future is set by what we decide and do today.

    What happened yesterday is over. You can not change it. So let it go. Don't waste your energy considering anger or unhappiness. It only stops you from moving forward in life.

    Look for the good in people. Celebrate the happy moments, big and small. Search for the chances for growth. Give helpful encouragement rather than unwanted criticism (批评). Be helpful whenever possible.

    In a word, life is serious but you can still be delighted and hopeful. Otherwise, what's the point?

    China's hot word, tuhao, may be in Oxford English Dictionary.

    In Chinese, tu means rude and hao means rich. In recent years, people use this term to describe those who spend money in an unreasonable way. The word became more popular with Apple's gold-colored iPhone, which is loved by China's rich people. The color became known as “tuhao golden”. The word is now often used to refer to people who have money but lack taste.

    There are two other Chinese hot words: dama and No Zuo No Die, which may also be taken in the dictionary. Dama, meaning middle-aged women, was first used in the Western media by the Wall Street Journal. Thousands of Chinese women were buying a large amount of gold when the gold price had gone down. Another phrase No Zuo No Die, meaning if you don't do stupid things, they won't come back to bite you, is also very popular. Other words, such as Maotai, Chinglish and dim sum have also been included in the dictionary.

    BBC World News recently made a special program called “Tuhao, let's be friends!” “The frequent use of Chinglish by foreign media suggests that foreign people are looking more to the lifestyle and popular culture of China,” says Zhang Yiwu, professor of Beijing University.

    What does this trend suggest about the Chinese language's influence?

    Xing Hongbing, a professor from Beijing Language and Culture University (BLCU) said “These show that Chinglish is now being accepted by the rest of the world and they play important roles in daily life of Chinese. Behind these Chinglish words and phrases are the Chinese culture. They are reflections of the changes and trends in the Chinese society and they help people from other countries to understand what's happening in China.”

    A new report says living in a city makes it harder for people to concentrate(集中) on some tasks. The research found that people who live in rural areas can focus better than people in urban areas. The study is from Goldsmiths College, which is part of the University of London. Head researcher Dr. Karina Linnell and her team made great contributions. They studied how two groups of people did the same "thinking tasks". The team went to a remote(偏远的) part of Namibia, southwest Africa, to study the Himba tribe. Himba people live a very basic life in the desert. They are still doing traditional farming. The team also studied members of the same tribe who had moved to the nearest town. Dr. Linnell said the tribe who lived in the desert did much better on the tests than those in the town. It's really interesting and shocking.

    Dr. Linnell said their research may lead to changes in the way companies operate. In the future, workers may move from cities to live and work in the countryside. Linnell said there are too many things around us in the city that stop us from thinking about one thing for a long time. This means we do not work at our best. She asked, "What if, for example, companies realized certain tasks would be better carried out by employees based outside of the urban environment? There their concentration ability is better. "The past century has seen billions of people move from the countryside to big cities. In the future, the trend may not continue. If Dr. Linnell's research is true, this century might see many of those people return to the great outdoors. Let's wait to see what will happen.

    The School has become aware that many students are being prevented from doing their work because of other students playing games and watching movies. We're sorry it's come to this, but we don't have enough resources to support everything, and our educational mission comes first.

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have-in just two years-nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable (商业可行性) generation of solar fuels that could replace coal, oil, and other fossil fuels.

Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and carbon dioxide. Researchers are exploring a range of possible target fuels, but one possibility is to produce hydrogen by splitting water.

Each water molecule (分子) consists of one oxygen atom and two hydrogen atoms. The hydrogen atoms are extracted, and then can be reunited to create highly flammable hydrogen gas or combined with CO 2 to create hydrocarbon fuels, creating a plentiful and renewable energy source. The problem, however, is that water molecules do not simply break down when sunlight shines on them-if they did, the oceans would not cover most of the planet. They need a little help from a solar-powered catalyst (催化剂).

To create practical solar fuels, scientists have been trying to develop low-cost and efficient materials that perform the necessary chemistry using only visible light as an energy source.

A new method was developed through a partnership between the Joint Center for Artificial Photosynthesis (JCAP) and Berkeley Lab's Materials Project, using resources at the Molecular Foundry and the National Energy Research Scientific Computing Center (NERSCC). JCAP focused on developing a cost-effective method of turning sunlight, water, and carbon dioxide into fuel. It is led by Caltech with Berkeley Lab as a major partner. The Materials Project is a program based at Berkeley Lab that aims to remove the guesswork from materials design in a variety of applications.

"What is particularly significant about this study, which combines experiment and theory, is that in addition to identifying several new compounds for solar fuel applications, we can also learn something new about the basic electronic structure of the materials themselves." says Neaton, the director of the Molecular Foundry.
