Yuan Longping, known as the “father of hybrid rice ”, is one of China’s most f    1    scientists. Yet, he considers himself a farmer because he a    2     works the land in his research. Indeed, his s    3     but strong body is just like that of millions of Chinese farmers, to whom he has d    4     his life.

Yuan Longping was born in 1930 in Beijing. His parents wanted him to p    5     a career in science or medicine. However, what c    6     him most was that farmers often had poor h    7       and sometimes even had a serious s    8    of food to eat. To tackle this c    9    , he chose to study agriculture and received an e    10     at Southwest Agricultural College in Chongqing.

The Internet has done much more for people than simply make l    1    more convenient.

People’s lives have been changed by online c    2     and social networks. Jan Tchamani, an English teacher, suddenly d    3     serious illness and had to quit her job. At age 50, she found herself out of work and stay at home with only her computer to keep her c    4    , After a while, she discovered that s    5     Internet could help her feel less lonely and bored. She was so inspired by the p    6     she met online that she decided to start an IT c    7    . Jan has started taking online c    8     to learn more about ho to use the Internet to make s    9     better. Her next goal is to start a charity w    10     to raise money for children in poor countries.

Yuan was born in 1930 in Beijing. His parents wanted him to pursue a career in science or medicine. However, what concerned him most was that farmers often had poor harvests and sometimes had a serious s    2     of food. To t    3     this crisis, he chose to study agriculture in a college.

After graduating in 1953, he worked as a researcher. Yuan realised that larger fields were not the solution. Instead, farmers needed to b    4     yields in their fields. How this could be done was a challenging question. Yuan was c    5     that the answer could be found in the creation of hybrid rice. One characteristic of hybrids is that they usually a    6     a higher yield than c    7     crops. Through i     8     effort, Yuan o    9     technical difficulties to develop the first hybrid rice. This hybrid enabled farmers to expand their o    10     greatly.

Yuan Longping, known     1     the “father of hybrid rice”, is one of China’s most famous scientists. Yet, he     2     himself a farmer because he continually works the     3     in his research. Indeed, his slim but    4     body is just like that of millions of Chinese farmers, to whom he has     5     his life.

China is w    1     known for its ancient c    2     which has continued all the way through into modern t    3    , despite the many ups and downs in its history. There are many reasons why this has been possible, but one of the main f    4     has been, the Chinese w    5     system.

At the b    6    , written Chinese was a picture-based l    7     . It d    8     back several thousand years to the use of longgu-animal bones and shells on which s    9     were c    10     by ancient Chinese people. Some of the ancient symbols can still be seen in today’s hanzi.

Economic development is necessary if we want to improve s    1    . There comes a time w    2     the old must give way to the new, and it is not possible to p    3     everything from our past as we move towards the future. Finding and keeping the right b     4     between progress and the protection of cultural sites can be a big challenge.

Big challenges, however, can sometimes lead to great s    5    . In the 1950s, the Egyptian government wanted to build a new dam across the Nile in order to control floods, produce electricity, and s     6     water to more farmers in the area. But the p    7     led to protests. Water from the dam would likely damage a number of temples and d    8     cultural relics that were an important part of Egypt’s cultural h    9    . After listening to the scientists who had studied the problem and citizens who lived near the dam, the government t     10     to the United Nations for help in 1959.

In g    1    , doctors in those days had two c    2    theories to explain how cholera spread. One theory was that bad air caused the disease. Another was that cholera was caused by an i    3    from germs in food or water. Snow s    4    to the second theory. It was correct, but he still needed p    5    . Consequently, when an o    6    of cholera hit London in 1854, Snow began to investigate. He discovered that in two particular streets the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why.
