Aside from teacups and rice bowls, China doesn’t do anything on a small scale. Sure enough, their recently-completed solar power array in Ningxia is huge.

The Ningxia array is the first of several giant renewable energy projects planned for     1     (construct) in the dry western areas like the Gobi, Tengger, and Taklamakan deserts.

China Energy Investment Corp says it is the first solar farm in the country    2     (include) an ultra high voltage power transmission channel that will bring the electricity     3     (generate) there to Hunan Province.

    5     the most recent Five Year Plan, the Chinese government     6     (outline) their intention to install 100 gigawatts of renewable energy by 2026. Installed capacity of renewable energy in China continued to expand in the first quarter,    7     (reach) 47.4 million kW.

Like most rural Chinese provinces, Ningxia, along with Xinjiang and Inner Mongolia — the provinces     8     the three deserts mentioned above lie, rely     9     (heavy) on coal for electricity.    10     is hoped that the major installations of solar and wind will accelerate development in these mostly-agricultural economies.

The artists of Dafen can paint like Van Gogh

The village of Dafen was once thought     1     (produce) the most oil paintings in the world every year.     2     (recognize) as the “world’s art factory”, Dafen impressed visitors with its many workshops, in which painters created mock masterpieces by Van Gogh, Monet and Warhol. But the village was always seen more as a production line     3     a place of culture. Today the future of Dafen may depend on     4     it is able to earn respect of the art world.

Some scientists think     1     idea of people living on Mars will come true one day. Stephen Hawking believed humans must move into space to survive. “Once we spread out into space and establish     2     (dependent) colonies, our future should be safe,” he said, Robert Zubrin, a rocket scientist, agrees and thinks starting with Mars     3     (make) the most sense. He thinks sending people to Mars will allow us to learn a lot--for example, about the ability of humans to live in a very different environment.

However, scientists will need to terraform Mars for people to be able to live. Terraforming means changing the environment on a planet so that it is similar to Earth's. One of the main goals of terraforming Mars is to warm it up     4     the average temperature there is about -60°C. One idea for warming Mars is to build factories there     5     produce greenhouse gases. This could take many     6     (century). However, it should lead to rainfall and the growth of plants,     7     (result) in more air that people can breathe.

Another big concern for scientists is whether humans can move to Mars and still live     8     (healthy) in mind and body. Not to feel bored, humans on Mars would always need to keep     9     (they) busy with various activities. And the people living together should all be able to get     10     and work together.
