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.

1.How many Chinese scientists headed for Antarctica on Oct 15th, 2019?

A.Fifteen. B.Nineteen. C.Fifty. D.Two hundred.

B.the first in the world to use two-way ice-breaking technology

C.one of the best research icebreakers in China

D.the second icebreaker made in China

3.According to Paragraph 3, scientists study ______ in Antarctica.

4.Which of the following best describes scientists’ life in Antarctica?
