Recently,people in US education have gotten extremely worried because a new report has shown that American students have a math problem.

    The 2015 Program for International Student Assessment（评估）(PISA) shows math scores in the US getting lower and no improvement in science or reading.PISA tests 15-year-olds from different countries and regions in their math,science and reading skills.About 540,000 students from 72 countries and regions took part in the assessment in 2015.

    US scores in reading and science were about the same as three years ago,leaving Americans near the middle of the bigger group.But the situation in math is much more worrying.The US average score was 470,be;ow the OECD（经合组织）test average of 490,meaning the US was No.40 among the 72 countries and areas.It was 12 points lower than in 2012 and 18 points lower than in 2009.So,what is going on with American students' math skills?

    One reason may be that the US does not teach math in enough depth."Students are often good at answering the first part of a problem in the United States,"said Andreas Schleicher,director of education and skills at OECD."But as soon as students have to go deeper and answer the more complicated part of a problem,they have difficulties."In comparison,many high-performing countries and regions in math teach a lot less but focus in much greater depth, especially when you look at East Asia,Japan and Singapore,according to Schleicher.

    Another reason may be the fact that many people in the US are unwilling to travel to foreign countries to learn better teaching practices."One of our biggest challenges in the US is that the teachers are not going out and seeing what high-performing countries do differently,"said Wendy Kopp,who started Teach for America,in a news program.

    Given that many people 's moods(情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie& the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates. Its founder is Chris Lee who grew up at his parents' comer store with one hand almost always in the jar of sweets.

    If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored (味道)chocolates.

    The CRF's produce is “green” made within the country and divided into10 lines, with the Alcohol Series being the most popular. The Exotic Series—with Sichuan pepper, red bean (豆), cheese and other flavors also—does well and is fun to taste. And for chocolate snobs, who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.

    American college students are becoming more adventuresome as they study abroad, showing less interests in English-speaking destinations such as Great Britain and Australia and more in such countries as China, India, Argentina and Brazil.

    Britain remained the most popular study destination in 2005, according to annual figures from the Institute of International Education, followed by Italy, Spain and France. But the number of American students studying in Britain and Australia descended a little, even as the number of American students abroad rose by 8%. The growth came in non-English speaking European countries and in Asia. China is now the eighth most popular destination for American students, attracting nearly 6,400 in 2005, up 35% from the number of the year before. Argentina and India saw increases of more than 50%.

    Allan Goodman, president of the Institute of International Education, said that a range of factors contributed to the trend, from growing awareness of globalization after the terrorist attacks on September 11, 2001, to programs such as former President Bush's National Security Language Initiative, which trains soldiers, intelligence officers and diplomats in foreign languages. “What Americans are doing is waking up and discovering there's a world out there,” he said.

    Other figures showed the flow of students in the opposite direction, from foreign countries into American universities. The institute found that international enrollment (入学) in American higher education remained steady at about 565,000. The figures are of keen interest to universities, which depend on foreign students for teaching and research help, and to policy-makers, who consider it important, as future foreign leaders may be familiar with the United States. The year of 2005 saw big increases in students from South Korea, Mexico and Taiwan of China. India sends the most students and China is No.2. Other countries that show large percentage increases in the number of students sent to the US include Nepal and Vietnam, while Japan, Turkey and Malaysia saw declines. About 58% of international students in the US come from Asia.

    Last night Mr. and Mrs. Rojas stayed home. It was cold and rainy and they didn't want to go out in the bad weather. Mrs. Rojas made some popcorn and ice tea. At 8:00, Mr. and Mrs. Rojas went into the living room, sat on the sofa and began the movie and ate and drank. At 8:15, Mr. and Mrs. Rojas realized they already watched the movie last year and they didn't want to watch it again.

    “Now what?” asked Mr. Rojas. “Let's play cards!” answered Mrs. Rojas. At 8:30 Mr. and Mrs. Rojas started to play cards. They were playing for about 10 minutes when Mr. Rojas looked out the window. The rain changed to snow and the trees were covered in beautiful white snow. “I'm happy we stayed home tonight. It looks beautiful outside but this weather is very dangerous to drive in.” said Mr. Rojas. “You're right,” said Mrs. Rojas, “but I'm bored. Let's play some music and dance.”

    Mr. Rojas was surprised. “Dance? But I really don't ….”

    “Oh come on!” Mrs. Rojas insisted. She put on a romantic CD and they both started to dance. They were dancing for about 1 minute when suddenly the music stopped and the lights went out.  Mrs. Rojas laughed. “We're just not very lucky tonight, are we?” she said. Mr. Rojas said, “Of course we're lucky! We are together!” He kissed her and continued to dance with her, in the dark and without music.

    All of us spend a large part of our lives at home — eating, sleeping, relaxing and communicating with our family members. Our home is a shelter for us, away from the noisy, busy, and polluted world outside — a place where we can let down our hair and dress casually. Eco­friendliness (环保) is a hot word today and we all know we should make our environment as eco­friendly as possible. This is not only good for our health, but also good for the outward environment. Here are some easy and helpful tips to make your home eco­friendly.

    Kitchen

    Plan the kitchen to be bright and airy so that you don't have to turn on the lights at daytime. Don't make wasteful use of the gas. Keep all ingredients for cooking ready before lighting the gas. Turn it to low when not required — always using it on "high" burns a lot of gas.

    Indoor plants

    Plants are extremely eco­friendly and can be used to make your home look lively. Apart from adding life to home, they give out O_2, thus making the air inside fresh. You can keep plants in your home, but be sure to show them some sunlight regularly. Also, if they are kept outside, clean their leaves with a wet cloth, as dust may be added to them. A home decorated (装饰) with plants looks attractive. Plants are a natural home decorating gift that shows concern about the environment. A green plant is a wonderful gift which will protect the earth and is sure to be appreciated.

    Saving water

    Most of the time, we take water for granted — we keep water running while brushing our teeth or washing clothes. Needless to say, this is a huge waste of natural resources (资源). Try to recycle water. For example, the water used for washing vegetables can be used for watering plants; the soapy water used for washing clothes can be used to clean the bathroom and kitchen.
