The dream of flying into outer space, cherished by the Chinese people for centuries, will soon come true.
China launched its fourth unmanned spacecraft (飞船)“Shenzhou Ⅳ” on December 30 at the Jiuquan Satellite Launch Centre in Gansu Province. It was the 27th consecutive(连续的 )and successful launch of China - made rockets since October 1996. This launch has made it more realistic for China to send a person into space on its own following Russia and the USA.
Qi Faren,leading designer of the spacecraft system, said all the functions (功能) designed for manned flights have withstood (经受住)the test of three previous, successful launches and return landings of the “Shenzhou” spaceships.
China launched the “Shenzhou Ⅰ ”, “Shenzhou Ⅱ ”and “Shenzhou Ⅲ ”spacecrafts in 1999,2001 and 2002 respectively.
“Shouzhou Ⅳ” was to make it a more comfortable place in which astronauts can live and work. All parts of the application system for manned flight are aboard the “Shenzhou Ⅳ”craft in all test flights.
China’s manned flight programme began in 1992. A number of unmanned test flights will be launched before Chinese astronauts are sent into space.
Leading scientists in charge of China’s manned space programme said the successful launch of the “Shenzhou Ⅳ” laid a solid foundation for the country’s future task of sending Chinese astronauts to outer space.
The spacecraft returned to the earth on January 5, after completing seven experiments in space.
Officials at the centre said that“ Shenzhou Ⅴ”, a manned spacecraft, is expected to be launched later this year.
How many countries can send a person into space on its own by now?
A. 2. B. 3.
C. 4. D. Not mentioned.
China’s manned flight programme began in ________.
A. 1992 B. October 1996.
C. 1999 D. January 2003
As a matter of fact, ________ .
A. “Shenzhou Ⅴ ”has been launched
B. “Shenzhou Ⅳ” was a manned spacecraft
C. “Shenzhou Ⅲ ”and“ Shenzhou Ⅳ” were not launched in the same year
D. the dream of man flying into outer space has come true in China
Which is the most suitable title for the passage?
A. The Successful Launching of “Shenzhou Ⅳ ”.
B. The Landing of “Shenzhou Ⅳ ”.
C. Chin a’s Manned Flight Programme.
D. The Third Country Sending a Person into Outer Space.

I used to be ashamed of my grandma. I know that's a 36 thing to say, but it was true until today, so I have to 37 it.
The 38 started when my friend Katy found Grandma's false teeth floating in a glass on the bathroom sink. I was so used to seeing them that I 39 took notice of them.

查看习题详情和答案>>The 2012 London Olympics had enough problems to worry about. But one more has just been added -- a communications blackout caused by solar storms.
After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. "A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is the greatest during a solar maximum when there is the greatest number of sunspots.
Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
Professor Richard Harrison, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advanced warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
