Unit 6 Space and beyond

1．Taken as a whole，the universe is absurd. —Bagchot

整体说来，宇宙无法理解。                         ——巴佐特

2．A grain of sand includes the universe. —Coleridge

一粒沙包含着宇宙。  ——柯勒律治

3．Nothing puzzles me more than time and space；and yet nothing troubles me less.                        —Charles Lamb

时空使我困惑最多，然而也令我烦恼最少。           ——查尔斯·兰姆

4．The universe is full of magical things，patiently waiting for our wits to grow sharper.                       —Eden Phillpotts

宇宙中充满着不可思议的事物，耐心地等着我们的智慧变得更加敏锐。                 ——艾登·菲尔波次

Located in a natural depression in Guizhou，China's Five­hundred­meter Aperture Spherical Radio Telescope，known as FAST，has identified six pulsars(脉冲星)after one year of trial operation.It is the first time Chinese scientists have discovered pulsars using a radio telescope independently developed by Chinese scientists，thus opening a “new era of Chinese original space discovery”．

China's FAST science impact on astronomy will be extraordinary，and has the potential to revolutionize other areas of the natural sciences.It will remain the global leader for the next 10 to 20 years.

Have you ever dreamed of visiting a planet in the Milky 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 shut­eye.They would have to sleep for years.

European researchers are now conducting hibernation(冬眠) 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.

What seems like science fiction is not completely unlikely.Researchers have been able to use chemicals to put living cells into a sleep­like state where they don't age.They have now moved on to small，non­hibernating mammals(哺乳动物)like rats.

According to Marco Biggiogera，a hibernation researcher at Italy's University of Pavia，the six­person Human Outer Planets Exploration Mission to Jupiter's moon Callisto，could be an opportunity to use human hibernation.The mission aims to send six persons on a five­year flight to Callisto，where they will spend 30 days，in 2045.

[探究发现]

1．Find out the purpose of hibernation experiments by the European researchers.

To know if man can sleep for years.

2．Find out the first try of the hibernation technology according to Marco Biggiogera.

The six­person Human Outer Planets Exploration Mission to Jupiter's moon Callisto.

3．Find out the main idea of the passage and then think of a proper title for it.

Hibernation study for space travel ;Deep Sleep for Deep Space Travel.
