Lots of foreigners don’t understand why so many Chinese people are sorrowful about Yuan Longping’s passing away.

This reminds me     1     an issue more than 20 years ago,     2     I was a Chinese journalist in the US. Some American scholars     3     (think) China could hardly realize food-sufficiency because of the     4     (limit) water resources, decrease of agricultural land due to industrial     5     (expand) and the fast population growth. Just at that time, Yuan Longping announced breakthroughs in planting the new rice.     6     (bring) to large area application, this technique improved the annual growth of rice greatly, which fed     7     population of 60 million--equal to the whole of the UK.

Western scholars’ prediction of China back then was indeed analyzing China’s problems, but they failed     8     (realize) that the Chinese people have the capability to deal with these challenges.

If they had had any knowledge of Yuan who worked devotedly for our country, they wouldn’t have made such pessimistic evaluations. Why did the Chinese people make     9    ? Why are so many predictions about China in the West     10    (accurate)? It’s time to change minds to better understand China.

Charles Darwin was an English     1     (science) who studied nature. He is known     2     his theory of evolution (进化论)．

Darwin was born on February 12, 1809, in Shropshire, England. In 1831, Darwin boarded a ship     3     (call) the HMS Beagle and set out on a fantastic five­year journey around the world. His goal was     4     (study) the natural history of the areas he was to explore. Darwin was     5     (amaze) at the variety (多样性) of species he saw on his journey. He noticed that although the different islands had similar animals and plants, many seemed to have changed to adapt (适应) to their local environments. He noted some     6     (difference) between the mockingbirds found on San Cristobal, Floreana and two other islands. This led     7     (he) to wonder why they varied from place to place.

Darwin first presented his theory of evolution by natural selection (选择) in 1858 to explain how animals adapted to their environment to survive. The idea of evolution     8     (be) not new then, but Darwin’s theory explained how evolution occurred. When Darwin published On the Origin of Species in 1859, the book was     9     immediate success. However, it was not popular with people     10     believed that all the animals on the planet had been made at the same time by one creator. But Darwin scientifically proved all the species on Earth had evolved from earlier species!
