    There are many ways to help improve your health like eating healthy food. Taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of（不管）age,some people need to sleep more while for some a few hours is enough.

    The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure （血压）.

    Why are so many people sleep-deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. In fact, people who sleep a lot are usually seen as "lazy". Also, you can sometimes hear some people say proudly that they don't have much time to sleep. They only sleep four or five hours a night. It seems that the less you sleep,the more work you'll do.

    How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas an expert in sleep. He says, " Sleep is like a credit （信用卡）card. When you sleep less,you are only borrowing time. You always have to pay it back. The more hours you don't sleep, the more hours you should sleep to 'pay back ' the hours on your 'sleep credit card.' "

    For those who value work more than sleep, they should listen to what a famous person once said. "Don't think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more."

    There are various ways in which to read body language so that you can understand how someone is feeling. Reading emotional clues （线索）is one of them.

    Crying is considered to be caused by an explosion of emotion in most cultures. Often times crying is considered a sign of sadness, but crying can also be an expression of happiness. Crying can also come about through laughter and humor. Thus, when judging crying, you'll need to look for other signs to determine the meaning of the crying. Crying can also be forced in order to gain sympathy or to cheat others. This practice is known as " crocodile tears" , an expression that draws on the wrong idea that crocodiles" cry" when catching prey（猎物）.

    Signs of threat include v-shaped eye brows wide eyes, and an open or down-turned mouth. In a similar way, arm tightly crossed over the other is a common sign that the person is angry and is closing himself off to you.

    When people show anxiety, they display increased facial movements, and their mouth made into a thin line. Individuals who are anxious may also play with their hands, unable keep them in one spot. Anxiety can also or have nervous legs. It can be conveyed when people seemingly unconsciously（无意识 地）tap their feet or have nervous legs.

    Embarrassment can be expressed by turning the eyes or shifting them away. If someone looks down at the floor a lot, they are probably shy, afraid, or embarrassed. People also tend to look down when they are upset, or trying to hide something emotional. People are often thinking and feeling unpleasant emotions when they are in the process of staring at the ground.

    There are also some signs of pride. People show pride by displaying a small smile, holding their head backward, and putting their hands on their hips.

    Big data（数据）is a 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, 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 extra 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 or 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.
