Antarctica (南极洲) is the coldest, driest and windiest place on our planet. What would it be like to live and work there? On Oct. 15th, 2019, 50 Chinese scientists set sail from Shenzhen, heading for Antarctica. This was our country's 36th Antarctic expedition. The ship, Xuelong 2, is the first icebreaker made in China. Xuelong 2 is one of the world's best research icebreakers.
It can sail to any place around the world in one trip without refueling (加燃料). It can work in temperatures as low as -30%℃. It is the first in the world to use two-way ice-breaking technology, which means that it can break the ice while moving forward or backward.
Because of Antarctica's special environment, scientists from around the world have been there to do studies for many years. The study of Antarctica's geology (地质) is also important. Rock in Antarctica can tell scientists what the weather was like a long time ago. And they can help scientists understand how the earth has changed over time. There are also many wild animals, such as penguins and seals. Scientists can learn how animals live in cold places by studying them.
As we all know, life in Antarctica is not easy－it's cold and sometimes dangerous. But scientists say it's still quite fun. For example, some scientists study how penguins walk, what they eat and why they move from one place to another. They are excited to see the cute animals playing around. They hope their studies can help protect them.
Xuelong 2 finished its tasks and returned to Shanghai on April 22, 2020.

The expression “down to earth”（脚踏实地） means being open and honest. It is easy to get on with someone who is down to earth. A down-to-earth person is the opposite of someone who acts important or proud.
Down-to-earth people could be important members of society. But they do not consider themselves to be better than others who are less important. A person who is filled with his own importance and pride is said to have his nose in the air.
Americans use another expression that is similar in some ways to down to earth. The expression is both feet on the ground. Someone with both feet on the ground is a person with a good understanding of reality（现实）. He may have dreams, but he does not allow them to have influence on his understanding of what is real.
The opposite kind of person is one who has his head in the clouds. Someone with his head in the clouds is a person whose mind is not on what is happening in real life. Such a person may be called a day-dreamer.
When we have both our feet on the ground and when we are down to earth. We do not have our noses in the air. We act honestly and openly to others. Our lives are like the ground below us—solid（牢固的）and strong.

Have you tried to run or walk for exercise and then given up? If you answered yes, you should try a new kind of exercise: aquatic (水中的) exercise. Aquatic exercise is like exercise on land, but you do it in a swimming pool. More and more people are trying aquatic exercise.
Aquatic exercise feels easier than exercising on land. Why? You weigh about 90% less in the pool. It is better for your knees than running or walking. Water is about 1, 000 times thicker and heavier than air. To move through the water, your body has to work four times as hard. As a result, you can burn more calories (卡路里).
In fact, most people say they feel more relaxed in the water. They stop thinking about the things that make them worried. They feel in control of their bodies. The cool, quiet environment makes them feel good.
But what if you are afraid of the water? No problem! There is nothing to worry about. Aquatic exercise is safe and easy to learn. It doesn't require any special skills. You don't even need to know how to swim. Aquatic exercise is for everyone.
