There are many TV programs on Chinese cuisines(烹饪)now.  A Bite of China(舌尖上的中国)is a new program and it's very popular．The CCTV Channel One show began to play on May 14th，2012．It was held by the award-winning documentary maker Chen Xiaoqing．The program tries to bring something new by presenting more cultural elements related to dishes，such as eating habits and the ethics(道德)of eating．It also offers insights into the geographical，historical and cultural dimensions of what Chinese eat．It can teach us how to make the food．So the program is sure to attract both food buffs and ordinary audiences．

    A Bite of China has seven episodes(片段)．Each episode lasts 50 minutes．Themes range from ingredients to preserved food．

    Food is always connected with people．To get enough good stories，the  production team spent three months doing research and interviews in about 60 cities before they started shooting．Filming lasted about nine months．

    A Bite of China captures social changes while presenting food cultures，such as，many families leave old people in their hometowns while other members work outside，the food of their hometown can remind them of happy times．

     Chen says the seven episodes might not be enough to capture the glory of Chinese food culture．

    Big data(数据) is lot of sets of information that are put together so they can be used by a computer program. The computer program looks for different kinds of answers or patterns in the data. Big data can have different kinds of information from many sources, such as information that comes from schools, social media sites(社交媒体网站), companies and governments. One set of data can have people's names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the computer.

    Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need more help in class. The teacher can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream.

    Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby so he, she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong.

    How can big data be used for good and bad things? It is because the computer programs used to look at big data and understand it are written by people. People think a certain way. Because they think a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people.

    You may know the English letters A, B and C. But do you know there are people called ABCs? Do you know there is such a thing as "a banana person"? How strange! ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a "banana person". A banana is yellow outside. So, when a person is a "banana", he or she is white inside—thinking like a Westerner and yellow outside—looking like a Chinese.

    Usually, ABCs know little about China or the Chinese language. Some of them don't speak Chinese. But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are overseas(海外的)Chinese. These people may be citizens(公民)of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are people of the People's Republic of China. For example, we all know the famous scientist C. N. Yang(杨振宁). He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen.
