Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.
"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.
Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陈代谢) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system.
There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的卫星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
1.European researchers are conducting hibernation experiments to ________.
A. ensure astronauts to get a complete sleep
B. find the secret of some creatures
C. make preparations for the journey to Jupiter’s moon Callisto
D. know if man can sleep for years
2.The sentence “What seems like science fiction is not completely unlikely” means ______.
A. Science fiction is people’s imagination.
B. Science fiction is imaginative, but it can be realized.
C. Things seem impossible may come true.
D. Things described in science fiction are sure to become true.
3.The passage implies that ________.
A. putting living cells into a sleep-like state is full of failure
B. Biggiogera is confident with the experiment
C. human’s hibernation needs no energy
D. medical research is the key to space flight hibernation system
4.What’s the best title for the passage?
A. Six humans to fly to Callisto
B. Human hibernation improves health
C. Space travel attracts people
D. Deep sleep for deep space travel

Have you ever dreamed of having a fashionable watch of great value?
A small watchmaker in Switzerland in 1922 designed the first automatic(自动的)watch to show the day, month, and date, Only seven of these splendid watches were ever made and these watches were almost lost to history.

Have you ever dreamed of meeting top scientists in person? If so, what would you want to ask them?
For Tan Fanglin, a 15-year-old girl from No. 2 High School of East China Normal University in Shanghai, her dream of meeting top scientists has already come true. In October 2019, she attended the World Laureates Forum for a second time, which had attracted 44 Nobel Prize Winners and 21 other world-class award winners. Tan was by far the youngest participant among the scientists invited to be at the meeting of the world’s sharpest minds.
Her discovery about the relationship between the Fibonacci sequence (斐波那契数列) and Bézout numbers (贝祖数) has won her many prizes in youth innovation competitions both in Shanghai and elsewhere in China. Her finding has been praised by the famous Canadian mathematician, Professor Rankin, who has been studying the same theme for five years but with no conclusions.
From a very young age, Tan has always been fascinated by mathematics. This is largely because her father, who teaches mathematics in East China Normal University, has a profound impact on her. According to Xu Jun, the head teacher, Tan doesn’t take after-school classes or too many extra exercises either. Her mastering of Advanced Mathematics and her good grades in school are thanks to the right study method. Her mother told Guangming Daily that Tan always treats studying and life with a positive state of mind so she can feel happy while studying.
Attending this forum enabled Tan to get more inspiration from top scientists. She even got the opportunity to talk with Gero Miesenbock, the 2019 Warren Alpert Foundation Prize winner. She asked Professor Miesenbock what he considered were the best personal qualities for conducting scientific research. Miesenbock encouraged her not to lose her passion and love for what she does. He said that accepting failures is crucial for researchers. He stressed that people all knew that even Thomas Edison went through hundreds of unsuccessful attempts before finally inventing the light bulb. The words made Tan feel inspired and she promised to keep her curiosity and interests in mathematics and overcome any obstacles in her research.
1.What can we learn about Tan Fanglin according to paragraph 2?
A.She is a student from East China Normal University.
B.She frequently participates in the World laureates Forum.
