Every year for over a millennium, fishermen have braved the subzero temperatures, biting winds and deep snow to search for     1     underwater fortune at Chagan Lake — one of the biggest freshwater lakes in our country.

Chagan is the only place in China     2     you can still find fishermen using a Mongolian fishing method that dates back centuries and has     3     (bare) changed over time. Holes are drilled in the ice     4     (lower) a 2-kilometer-long net into position underwater. Once it fills up with fish, the net is pulled out of the water using a giant wheel     5     (turn) by Mongolian horses. The largest fish in the     6     (season) first catch is believed to be lucky, and will go to the highest bidder at the auction (拍卖).

To ensure that this tradition can continue     7     damaging the lake’s ecology, fishermen keep nature in mind throughout the process.     8     (avoid) the use of modern vehicles helps reduce the chance of polluting the lake water, and the number of fish that can     9     (catch) is capped to ensure that there will be fish for years to come.

Also, over the past few years, the money from the auction has been invested into protecting the lake and surrounding environment. And during the summer, private fishing without     10     (permit) is strictly prohibited. These preservative measures have kept the tradition alive for thousands of years and certainly will be passed on to future generations.

States and space agencies     3     (work) on space exploration since the first space launch. The first space launch led to the first human space flight,     4     led to the first moonwalk. Nowadays focus has shifted to joint human and robotic missions, near - Earth asteroids (小行星), Mars and destinations beyond our own solar system.

Space exploration and the innovation     5     (involve) in it are essential drivers for opening up new areas in space science and technology. That produces new partnerships     6     develops capabilities that create new opportunities for     7     (address) global challenges. Space exploration also motivates young people     8     (pursue) education and careers in science, technology, engineering and mathematics (the STEM disciplines).

Though the precise nature of future benefits from space exploration is not easily predefined (预先确定), current trends suggest that significant advantage may     9     (find) in areas such as new materials, health and medicine, transportation and computer technology. As the benefits of space exploration and innovation become     10     (well) known, increasingly more countries and non - governmental entities are interested in engaging in exploration and innovation.
