We all need physical exercise. Exercise uses up food we eat and keeps the body energetic. If you exercise several times a week, you will stay happy and healthy.

Some Western countries, such as the United States, have problems with exercise. In the US, many people do not have enough exercise because it is hard for them. People have to work from morning to late afternoon, so they don’t have time to take exercise. They work in office buildings, sitting in chairs all day long in front of computers. It is impossible for them to get much exercise in this way.

Some Westerners can get exercise walking from their homes to work. However, most people cannot do this. It is too far from their homes to their offices. They have no choice but to drive to work. In fact, some have to drive one or two hours to their offices. This is not good in two ways. First, these people don’t have a chance to exercise because they are sitting in their cars for two to four hours each day. Second, driving is challenging especially in rush hours and needs too much attention. It makes a person very tired. So, when these people arrive home at night, they don’t want to take exercise after work.

Today, many people in the West are overweight, which causes health problems for them. Doctors say exercise can help people both lose weight and improve their health. So many people are trying to get more exercise. But it takes time to change, and when people don’t see a difference right away, they will lose patience and stop exercising.

Return to the moon

It might not be long until humans uncover the secrets of the far side of the moon. China’s Chang’e 4 robotic probe (探测器), which is set to become the first probe to land on the moon’s far side, was launched successfully on Dec 8, Xinhua reported.

The moon rotates (自转) at the same speed that it orbits (绕…运行) Earth. Therefore, the same side of the moon always faces Earth. The far side of the moon is the side that we cannot see. We don’t know much about it so far.

However, the far side of the moon is an ideal (理想的) place for scientific research(研究). It is exposed (暴露) to solar winds that may have formed unique minerals (矿物质) and other resources. And since the far side is less affected by Earth’s gravity, scientists can make clearer observations of deep space from there, according to China Daily.

But it is hard to land on the far side of the moon. Spacecraft that land there cannot receive any radio signals(信号) from Earth. To solve this problem, China launched a relay satellite (中继卫星) called Queqiao into space in May. Through Queqiao, scientists can control and operate Chang’e 4 and make sure it will land in a specific(特定的) area.

The probe’s travel time is also important. Chang’e 4 is expected to land on the moon on Jan 2, China Daily reported. It will travel through space for more than 20 days before landing. This is longer than Chang’e 3, which was in space for about 12 days before landing.

The travel time was changed because scientists want Chang’e 4 to land on the moon when it is daytime. This way, the spacecraft’s solar panels ( 太 阳 能 板 ) can receive energy from the sun and allow the probe to start working. A single day on the moon is about 28 days on Earth. Therefore, Chang’e 4 will keep orbiting the moon before landing as it waits for daytime, according to Sun Zezhou, chief designer of Chang’e 4.

Did you know? Chang’e 4 took some plant seeds and eggs to the moon. It was hoped that Chang’e 4 was able to do experiments with them. These were the first biological experiments to take place on the moon.

1.Is Chang’e 4 the first probe to land on the far side of the moon?

2.What does the far side of the moon refer to(指代)?

3.Why does the same side of the moon always face Earth?

4.How did Chinese scientists solve the problem of no signals?

5.Why do scientists want Chang’e 4 to land in daytime?

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.

We live in a fast-paced(快节奏的), technology-packed world where we spend most of our time indoors playing computer games or using social media(媒体). But do you remember when you spent most of your time outside, running, playing, and laughing with your friends?

Leaving your tech behind may seem difficult, but if you lose yourself in nature, you’ll probably forget all about it. Scientist Albert Einstein once said, “Look deep into nature, and then you will understand everything better.”

In the US, June is Great Outdoors Month. They want to get more kids outside to have active fun once again. Former(前任) US President Barack Obama wrote in a paper declaring(宣告) the day in 2012, “Nature offers each of us the chance to get active, discover something, and make our relationships with family and friends strong.”

The US Union Creek Resort website noted, “We all know how fast life can be, so it’s never too soon or too late to create happy memories that we will cherish and share forever.”

Besides making us feel happy, science supports the idea that outdoor activities can cut down stress. “Fresh air and sunlight have the largest advantages,” wrote Susanne Preston, a mental health expert at South University, US. “With increased exposure(暴露) to natural sunlight, incidents of seasonal affective disorder(季节性情绪失调) fall and the vitamin D in people’s skin helps to relax their moods(心情).”

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.
