Big data (大数据) 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 (预测) 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 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.

On January 27, in order to win the new pneumonia Resistance War(抗击新型肺炎战), the Ministry of Education issued (公布)a notice on putting off the start time of school in spring 2020. It was said that school should not start before February 17. The exact start time of school will depend on situations and further notices.

However, many parents are very worried that putting off the start of school may affect children’s studies. If they have such a long winter vacation, children will not learn any knowledge, read books or study at all. They may forget what they have learned before. Staying at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health.

In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice, that is, to organize online teaching and create a network platform(平台), where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.

It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection(感染) of the disease, but also make them study at home, improve their learning ability, and truly achieve “no suspension of classes”. Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.

Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus and other knowledge popularization; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home.

1.Parents worried about putting off the start time of school because ________.

A.children may be infected by virus B.they don’t like the idea of online learning

C.children’s study may be affected D.parents have no time to look after children

2.Except for learning at home, what is also necessary according to the writer?

A.To keep playing online games. B.To keep touching different people.

C.To do some physical exercises outside. D.To teach children about health knowledge.

3.Which is TRUE according to the passage?

A.Students would rather go to school. B.The date of going to school is decided.

C.Online teaching will help students study. D.Parents believe children can teach themselves.

4.What’s the best title for this passage?

A.A Special Way to Learn at Home B.A New War with a New Chance

C.A Way to keep Mentally Healthy D.A Method to Make Parents Worried

The store was closing for the night. Young Alfred Higgins, the shop assistant, was ready to go home. Mr. Carr stared at him and said, “Hold on, Alfred. Maybe you’d be good enough to take the things out of your pockets and leave them here before you go.” Alfred’s face got red. After a few seconds, he took out what he had stolen. Mr. Carr said, “Maybe I should call your mother and let her know I’m going to have to put you in prison.”

Alfred thought his mother would come rushing in, eyes burning with anger. But, to his surprise, she arrived wearing a smile. “Hello, I’m Alfred’s mother. Is he in trouble?” she said. Mr. Carr was surprised, too. He had expected Alfred’s mother to come in nervously, shaking with fear, asking with wet eyes for a pardon for her son. But no, she was calm, quiet and pleasant and was making Mr. Carr feel guilty. Soon Mr. Carr was shaking his head in agreement with what she was saying. “You are right” he said, “Sometimes, a little good advice is the best thing for a boy at certain times in his life, and it often takes the youth long time to get sense into their heads.” And he warmly shook Mrs. Higgins’s hand.

Back home, without even looking at Alfred, the mother said, “You are a bad luck. It is one thing after another, always has been. Why do you stand there so stupidly? Go to bed. “In his bedroom, Alfred just took pride in his mother’s strength. He felt he must tell her how great she was. As he got to the kitchen, he was shocked by what he saw. His mother was lifting the tea cup, her hand shook, and her face became a frightened, broken one. It was no longer cool, bright as he saw earlier in the store. With her lips moving nervously, she looked so old.

Alfred watched his mother and he wanted to cry. He realized all the troubles he brought to his mother. It seemed that this was the first time he had ever really seen his mother, especially shaking hands and the deep lines of worry in her gray face. He knew his youth coming to an end.

What can be both red or green, round or sharp, big or small, and more importantly, loved or hated by someone? Yes, the answer is chilies(辣椒).

Many of us in China enjoy adding chilies to our food, but did you know that this spicy(辣的) vegetable could also be dangerous? A 34-year-old US man recently ended up in hospital after eating a Carolina Reaper, the spiciest chili people have ever known so far. After taking just a single bite of one, the man suffered from serious headaches in the following days, reported BBC News.

In fact, eating spicy food causes stomachaches and headaches. But if chilies are harmful, why do people like to eat this vegetable? So what makes people love chilies so much? The human body is influenced by natural chemicals that produce “a sense of happiness”, noted BBC News.

And chilies are good to people in another way. Scientists found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The death rate is 14 percent lower for those who eat spicy food six to seven times a week. This encourages people to eat more spicy food to improve health and bring less death risk at an early age. So, don’t worry if you love spicy food. It seems that chilies are actually good for us.
