They learned of the impact（影響） working couples and single parents were having on their children. Fear is the biggest problem faced by children at home alone. One in each three latchkey children the Longs talked to reported being scared. Many had nightmares and were worried about their own safety.

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 ______. A.what big data is and how it is usedB.what schools and hospitals people likeC.where important data is collected and storedD.how big data is controlled by governments and panies（2）One pany uses weather information to ______.
