Both Lang Ping and Michael Jordan are living legends of sports as they not only are     1    in their sport but also set good     2    by helping others.

Lang Ping is loved by fans at home and    3    . She is successful both as a player and as a coach of volleyball. The     4     she showed as a coach was impressive.

Michael Jordan,     7    as “Air Jordan”, changed basketball with his graceful moves and jumps.     8     made him unique was not only because of his skills but also because of his mental strength. He refused to give up in time of failures and kept on learning from     9    , which was the secret to his success.

It is said that the     1     use of chemical pesticides and artificial fertilizers can sometimes     2    both the land and people’s health. For     3    , pesticides can do     4     to the land by killing not only bacteria and insects, but also     5     ones. In addition, these chemicals can stay in the soil and underground water sources for a long time,     6     affects the crops grown on the land, in turn, the animals and humans who digest them. What     7     people is that these chemicals may harm their health and even cause cancer.     8    , some pesticides like DDT have been prohibited in most countries because of the damage they cause to people and the     9    . Besides, crops     10     with chemical fertilisers usually grow too fast to be rich in nutrition.     11     from their     12    , they look beautiful but they have a     13     of essential minerals and flavor. So some people are considering an     14     to chemical farming like organic farming though there is still a long way to     15    .

As a     1     to farmers’ poor harvests and even a severe     2     of food, Yuan Longping was determined to devote his life to     3     this crisis. After     4    , he realised that what farmers needed most was to boost     5     in the fields. Yuan was     6     that the answer lay in the creation of hybrid rice, one     7     of which is that it usually achieves higher output than     8     crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general     9     that this could not be done. Through intense effort, Yuan managed to     10     this incredible crop. It is     11     that about 60 percent of domestic rice     12     in China is comprised of crops generated from Yuan’s hybrid strains. His     13     has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of     14     and unconcerned about celebrity or fortune, Yuan continued to turn one vision after another into     15    .

For most people before the mid-20th century, it was impossible to travel into space. However, it was some scientists’     1     to help humans to fulfill their dream of     2     space. With many experiments done, they had rockets made successfully, which could escape Earth’s     3    . Then on 4 October 1957, the Sputnik 1 satellite was launched by the USSR and     4    orbited around Earth. Some time after that, the USSR     5     on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to go into space. Over eight years later, on 20 July 1969, American     6     Neil Armstrong said, “That’s one small step for a man, one giant     7     for mankind.” when he stepped on the moon. Following Russia and the US, China was the third country to send humans into space on its own in the Shenzhou 5     8     in 2003 when Yang Liwei successfully     9     Earth, which was a main     10     for China.

Artificial intelligence aims to create intelligent machines. To achieve the aim, many approaches to     1    (create) true AI have been put forward. The dream of AI     2    has been around for centuries has finally become a reality. Nowadays, AI is already being applied in many fields. From autonomous vehicles to domestic robots, from     3    (recommend) systems to computers writing novels, AI has     4    unlimited number of applications. The technology     5    (transform) the way we live. However, the question is, where will all this lead?    6    we become more and more dependent on computers, some scientists are urging us to think about the dangers     7    (pose) by the advances in AI. Stephen Hawking, for example,    8    (warn), “The development of full artificial intelligence could spell the end of the human race.”     9    (apparent), such warnings demand our attention. We need to make sure that we will not fall victim     10    AI.

The first day I was in senior high school, I felt     1     (焦虑的) and awkward. I was frightened that I could not     2     (留下好的第一印象). What if the     3     (讲座) were hard?     4     (终于), after     5     (登记) in the registration office, I had my first chemistry lesson. The teacher’s teaching strategy and     6     (方式) were so     7     (有组织的) that we could all     8     (集中精力于) his experiment and     9     (记笔记). During the break, I     10     (交换) ideas with my partner and found the guy     11     (自信的) and     12     (外向的). His     13     (目标) was to become a     14     (设计师) and design for his company.
