Part of Earth's beauty comes from its oceans. Ocean scientists study the chemical make-up of the ocean, weather patterns, the geography of the ocean floor, and many other areas. Their work is exciting, although sometimes dangerous. Using technology to do certain tasks helps. For example, robotic arms are used for very dangerous tasks.
One basic part of ocean study is understanding waves and how they work. Wind is the great maker of waves. The waves we know are mostly produced by winds blowing over the sea. They are directly connected with the wind speed and the time that wind lasts.
Sometimes ocean life can be seen in the wave. Living things seem to be staying within the wave, moving slowly inside it as if they were weightless. Besides the beauty of waves, scientists are interested in their technical ways. The diagram of waves shows how scientists examine waves. Waves are measured (测量) from the top (crest) to the bottom (trough). This allows scientists to find out the height of a wave. They also measure waves from crest to crest to determine (测定) the length of a wave.
During serious storms, huge waves might cut a sea ship apart. Ships are at great risk of winding up as broken pieces after being hit by the force of a huge wave. By understanding the ocean, scientists can prevent this breakup of ships by predicting when the water will be too dangerous for people and their ships. The study of waves and the ocean also allows scientists to make sure how certain beaches were formed. By studying the oceans, a great deal can be learned about the surface we live on.

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.

Yakutia is a place where temperatures fall to as low as-50℃. Thick clothing doesn't help there. The best way to keep warm is with animal fur（皮毛）.
In Mong Kok，Hong Kong，there are 165，.000 people per square kilometer. Apartment blocks fill the sky. There are shops on the side walk and it's difficult to walk in the streets.
People in La Paz，Bolivia live 3.5 km above sea level（海平面）.Hot drinks are a little cooler here because water boils（沸腾）at a lower temperature！
It doesn't rain very often in the Atacama Desert in Chile. In fact，it rained in 1971 for the first time in 400 years！People get water from the fog（雾）.And it's a perfect place for studying the stars because the sky is very clear even at night.
In Mali，West Africa，people have to get up early before it gets too hot. Traditionally，they wear clothes that cover all of their body because such clothes can protect them from the high temperature！

【推荐1】Winter is cold in some places. Many plants do not grow during winter. Some plants die. Snow and ice may cover the ground. It can be difficult for animals to find food during winter. Animals get through this time in many ways.
Birds and butterflies can fly. Many of them leave. They go to a place with nice weather. Then they come home in the spring. We call this migration (迁徙). Migrating is a good way to avoid the cold.
Another good way to avoid the cold is to sleep through it. Many animals hide during the winter. Their bodies slow down. They save their energy (精力). They do not eat. They depend on their fat (脂肪). They do this until food returns. We call this hibernation (冬眠). Snakes, frogs, and bears hibernate.
Some animals store (储存) food in their homes. They do not sleep all winter, but they do much less. They live on what they saved in the summer and fall. This is what squirrels(松鼠) do.
Other animals tough it out (忍受). They do not leave. They do not hide. They must survive (生存) in winter. Sometimes nature helps them out. Some animals grow thicker coats in the winter. Other animals change color. A kind of foxes are brown in the summer. Their coats turn white in the winter.
Winter may be pretty. It is nice to see snow on the trees. But it is dangerous too. People are also at risk. You can get frost bitten (冻伤) or worse. How do you beat the winter? Do you wear a thick coat? Do you stay inside? Or do you live somewhere warm?

【推荐2】Usually before an earthquake happens, people don’t know it is on the way. And these earthquakes are very dangerous. In fact, earthquakes kill more people than snowstorms and rainstorms every year. So scientists are looking for ways to predict (预测) earthquakes. Now they can predict the earthquake, but it is not always right every time. And scientists can say that an earthquake is possible to happen in some place, but they can’t predict the right place or time. And they can’t tell how strong the earthquake will be.
How do scientists make these guesses? First, scientists make sure which place the big earthquake will strike by studying the earth plates (板块). Second, scientists study the history of the place where earthquakes happened. Scientists can guess how often an earthquake may happen in this place. Third, scientists watch underground rocks for months. When rocks break, earthquakes happen. Last, scientists watch the water to predict an earthquake. Scientists hope that one day we can predict earthquakes.

How do you decide where to go on holiday? Is it the local places of interest? Or do you choose your next holiday just for delicious food?
“Food tourism” is that people travel to new places to try the local food. It is now becoming popular among visitors. There are many forms of food tourism, such as trying street food, visiting food markets, or eating at local restaurants.
A recent survey found that about 75% of Americans have traveled for food in the last five years. They said the top four countries they would visit for their food are Italy, France, Spain and Japan.
Food is an important part of holidays for British people, too. A survey team asked 2,000 British people about their main reason for a holiday. 61% of them said “the food”. And 41% said they would travel hundreds of kilometers to find the perfect meal. The top three European countries they would choose to visit for food are Italy, Spain and France.
The survey also found that British people like to try new and different foods most when they are traveling, and nearly half of people believe that they are more adventurous (胆大的) with what they eat when they are away from home.
