Many of us have had the same "pleasant surprise". After you mark a song as a favorite on a music app(程序), it suggests songs of the same kind to listen to.

Big data(数据)is a lot of sets of information that are put together so they can be used by a computer program. It can have different kinds of information from many sources(来源), such as information that comes from schools, social media sites, companies, and governments  Another set can have what they like, where they go to school, and how much time they spend on the computer.

The government uses it to understand how many people travel on buses or trains. The information is then used to make bus or train systems better. 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. 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.

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.

A. Big data can be used in many ways.

B. Why do we use big data for bad things?

C. Big data can also be used for bad reasons.

D. How can big data be used for good and bad things?

E. One set of data can have people's names and addresses.

F. In fact, this magic, mind-reading power depends on data.

①Most people who move to a foreign country may experience a period of time when they feel very homesick and have a lot of stress. This feeling is often called "culture shock (文化冲击)". It is important to understand it and learn how to deal with it if you want to adapt successfully to your new home's culture.

②There are four stages that you will experience after you move to a foreign country. The first stage is usually referred to as the "excitement" stage. When arriving in a new environment, you'll be interested in the new culture; everything will seem exciting and everyone will seem friendly.

③But it won't be long before you move from the "excitement" stage to the second stage. The excitement you felt before changes to stress. It seems that everything is difficult. The language is hard to learn, friends are difficult to make, and even simple things like shopping have become a challenge. It is at this "stress" stage that you are likely to feel worried and homesick. This is the stage which is referred to as "culture shock".

④However, culture shock doesn't last for very long. If you are one of those who solve it successfully, you'll move to the "recovery" stage. At this stage, you start to understand and accept the way things are done and the way people behave in your new environment.

⑤The last stage is the "home" stage. This is the stage when you start to feel at home in the new culture. You start to learn from your new home and to like something of the new culture better than those of your own culture.

⑥Culture shock is normal. Everyone in a new situation will go through some form of it. Continue to be brave! And overcoming culture shock will be a piece of cake.
