The puter 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 es from schools, social media sites（社交媒體網(wǎng)站）, panies and governments. One set of data can have people39。s names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the puter. 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 pany 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 puter 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.（1）This reading is about ______.

So they can39。t learn it well. But English is very easy for me. I39。m good at it. I39。m very glad to tell you something about how I study English.First, I think an interest in English is very important. When I was in Grade One, we had a new subjectEnglish. It was fresh to me. I became interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! Since then, I have been learning English harder and harder. Our English teacher often taught us English songs, and the songs sounded nice. I often think how interesting English is! Second, English is another language different from our Chinese. We should learn it in the following ways: Listen to the teacher carefully in class, speak bravely, read aloud and have a larger and larger vocabulary, and then practice again and again. And I have a good habit: whenever I have a question, I must make it clear by asking our English teacher. How happy I am when I understand it! Besides, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So, to do more reading is an important way to learn English well. And I also do some exercises in our workbooks, and I keep English diaries. English has bee a close friend of mine. Now I have learned English for more than two years. I am always in the first place in our class. Of course, I hope every classmate of mine can learn English well, too.（1）Why do some students often have a headache when studying English?
