还原短文(二) 成长引导 +科学技术 请阅读下面短文,根据短文内容,从方框内所给的选项中选出能填入空白处的最佳选项,使短文意思通顺。 选项中有一项为多余项。 A Too many people want others to be their friends, but they don't give friendship back. That is why some friendships don't last very long. 1. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous(慷慨的); be understanding. Honesty is where a good friendship starts. Friends must be able to trust one another. If you don't tell the truth, people usually find out. If a friend finds out that you haven't been honest, you may lose your friend's trust. 2. Generosity means sharing and sharing makes a friendship grow. You don't have to give your lunch money or your clothes, of course. Instead you have to learn how to share things you enjoy, your hobbies and interests. Naturally you will want to share your ideas and feelings. 3. They tell your friend what is important to you. By sharing them you help your friend know you better. Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. 4. So to be a friend you must listen and understand. You must try to put yourself in your friend's place so you can understand the problem better. 5. But all true friendships have three things in common. If you plan to keep your friendships, you must practice honesty, generosity and understanding. A.To have a friend, you must learn to be one. B.A friend in need is a friend indeed. C.No two friendships are ever exactly alike. D.Turning to a friend can be the first step in solving the problem. E.These can be valuable to a friend. F.Good friends always trust one another to speak and act honestly. B Big data(数据) is a lot of sets of information that are put together so they can be used by a computer program. 1._______Big data can have different kinds of information from many sources, such as information that comes from schools, social media sites, 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. 2. 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. 3. 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 or she does not get sick. 4. 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. 5. 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. A.Some schools use big data to understand which children may need extra help in class. B.Big data can be used in many ways. C.Big data can also be used for bad reasons. D.The computer program looks for different kinds of answers or patterns in the data. E.Because they think a certain way, they build a model of those ideas.
