China’s second manned(人造的) space flight will be done by two astronauts(宇航员) over five days in 2005. “Shenzhou-VI will be sent into space sometime in 2005,” said Zuo Saichun, a spokesperson of the China Aerospace Science and Technology (CAST). “The spacecraft(宇宙飞船) will make new breakthroughs(突破性进展) in China’s manned space technology.”

Unlike Shenzhou-V, a little more than a year ago (in October, 2003), the next flight will see two astronauts fly in space for five days. Their capsule (太空舱) is designed to be capable(能够)of orbiting(绕轨道运行) for a whole week, the spokesperson said. “For the first time, astronauts will enter and live in the orbital module(舱) of the spacecraft to do scientific experiments,” said a statement from CAST. CAST did not say what those experiments will be.

In Shenzhou-VI, scientists have changed the spacecraft’s configuration (构形) to reduce its weight, and tried to improve the performance of on-board equipment. They have also worked to make sure of the energy supply of the spacecraft and further improve its safety. So far, scientists have worked out ways to solve problems on environmental control and life support. Shenzhou-VI will be sent into orbit atop(在……顶上) a Long March 2F rocket.

Meanwhile, a model of the Chang’e-1 satellite is expected to be sent to orbit the moon in two years. The satellite, part of the three-stage programme, would be followed by the landing of an unmanned vehicle on the moon in the second stage by 2010 and collecting samples(样品) of lunar soil by 2020 in the final stage, according to Sun Laiyan, director of the China National Space Administration.

D.lunar soil collecting小题3:. Which of the following does NOT belong to the three-stage programme?

    

A.Shenzhou-VI’s being sent into space.

  

B.A model of the Chang’e-1 satellite will be sent to orbit the moon.

  

C.The landing of an unmanned vehicle on the moon.

  

D.Collecting samples of lunar soil. 小题4:. The passage mainly tells us ______.

    

A.some problems need solving before Shenzhou-VI is sent into space

  

B.Shenzhou-VI will be sent into space in 2005

  

C.what China’s space programme is
