According to legend, Wan Hu, a Chinese astronaut, was crazy about the stars and had a rather bold (大胆的) plan to get     1     (he) closer to them. He set out to become the world’s first astronaut. Picking up on China’s then developed technology in rocketry, he took up the task of building a spaceship.

Wan Hu’s pioneering spacecraft     2     (build) around a strong chair, two kites and forty-seven of the largest gunpowder- filled rockets.     3     the launch day, Wan Hu strapped (用绳子系) himself in the chair and called upon his forty-seven servants, each armed with a flaming torch,     4     ( light) the forty-seven fuses (导火线).

Their job done, the servants speedily ran to a safe     5     (distant) and waited nervously.     6     came next was a loud noise. When the smoke eventually cleared, Wan Hu, the Chinese astronaut, and his chair were nowhere to be seen. Whether Wan Hu     7     (actual) made it or not has never been made clear.

Despite (尽管) the fact     8     the story is considered untrue by some people today, Wan Hu found his place in Chinese popular culture.

At the beginning of the 21st century, China finally launched a man into space and turned Wan Hu’s centuries-old dream into     9     (real). In 2003, Yang Liwei was launched aboard Shenzhou 5,     10     (become) the first person sent into space by the Chinese space program.

If there is one thing that distinguishes China’s considerable effort in expeditions to the moon from other countries, it is China’s launch that is one     1    (true) carried out in the name of the advancement of humanity, unshaded by the cloud of the Cold War and an urge to demonstrate its power just     2    (make)other countries feel on edge.

The Chinese nation has always held a flame for the moon. The spacecraft, Chang’e,     3    (name) after the Chinese moon goddess.     4     it may be overly poetic to compare modern human     5    (attempt) at understanding the universe with a legend, we should by no means underestimate     6    significance of scientific discovery for the benefit of all.

As the Chang’e-5 returns     7     the much-sought-after and youngest lunar sample, the international community is charged with excitement and ambition to explore its analysis. Thomas Zurbuchen, associate administrator of NASA Science Mission Directorate wrote: "Congratulations to China on the     8    (success)landing of the Chang’e-5. This is no easy task. When the samples     9    (collect) on the Moon are returned to Earth, we hope everyone     10    (benefit) from being able to study this precious samples that could advance the international science community."

Firstly, exploring space has already made a     1     (different) in the fight against world hunger. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data     2     land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful     3     (recommendation) and advice for farmers. As a result, space-based science has helped farming in its efforts to grow enough food to feed Earth’s     4     (increase) population.

When Lin Zhanxi first introduced mushroom cultivation(培育) to the Gobi Desert residents of Ningxia, he didn’t expect such a phenomenal success.     1     inventor of juncao, a method that uses grass cuttings as substrate (培养基) for growing eatable and medicinal mushrooms, has long been committed     2     expanding the method in poverty relief.

In the 1980s, as a professor at Fujian Agriculture and Forestry University, Lin experimented with grass instead of logs to grow mushrooms because logs weren’t     3     (ready) available for many rural households while grass,     4     leaves and roots can be used for ecological management, is an essential multi-functional agricultural resource. In 1986,Lin made it, and soon his method     5     (adopt) by 51 counties in Fujian.

When juncao was made a key project in the pairing-off cooperation between Fujian and Ningxia in 1997, Lin advocated     6     (take) advantage of abandoned cave dwellings(窑洞) for growing mushrooms in Ningxia. The project doubled the farmers’ yearly income that year.

The success made juncao     7     (promote) in 506 China’s counties and it was then introduced to 106 developing countries. This world-famous innovation     8     (bring) welfare to millions of people so far. What touched Lin most during his journey to other countries to help develop juncao technology was that a foreign minister even named his daughter after juncao in honor of China’s     9    (assist).

“I feel I have a new mission     10     (shoulder), even after China wins its battle to reduce poverty. I can still foresee the importance of juncao in helping farmers better their situation and improving the ecology and the environment around us,” he said.
