President Xi Jinping signed a presidential order on Tuesday to award four people national medals and honorary titles for their outstanding contributions     1     fighting the COVID-19 pandemic.

Zhong Nanshan, 84,     2     excellent disease expert, was awarded the Medal of the Republic, the highest national honor, for his outstanding work in fighting COVID-19 in China. Three others were also awarded the ‘People’s Hero’national honorary title for helping fight against the novel coronavirus(新冠病毒). They are Zhang Boli, a    3    (tradition) Chinese medicine expert; Zhang Dingyu, head of Wuhan’s Jinyintan Hospital and Chen Wei, a medical scientist    4    made major achievements in COVID-19-related basic research.

Zhong also has long been devoted to the research, prevention and    5    (treat) of major infectious and chronic respiratory disease(慢性呼吸病), and has a long record of    6    (achieve). He was a major figure in the fight against the SARS outbreak in 2003 in China.

    7    (follow) the COVID-19 outbreak, the Chinese government encouraged the country    8    (contain) the disease in Wuhan, Hubei province, after the city was locked down in late January. More than 42,000 medical workers from across the country    9    (send) to Hubei to fight the disease.The pandemic has been     10    (effective) placed under control on the Chinese mainland since early March.

Perhaps no other scientist has had a greater impact     1     China’s aerospace science than Qian Xuesen. Born in Hangzhou in 1911, Qian attended schools in Beijing and entered Shanghai Jiao Tong University to study Railway Mechanical Engineering. However, he switched his major to aviation     2     (advance) China’s aerospace after the Songhu Battle broke out. After finishing his graduate studies in the United States, Qian became a pioneer in American jet and rocket technology and founded the Jet Propulsion Laboratory with several other people.

Qian returned to China in 1955 after he     3     (overcome) some difficulties and was put in charge of not only     4     (develop) China’s rocket science but also its space and missile programme. Under Qian’s leadership, China made many     5     (breakthrough) in aerospace. Therefore he earned the name of “    6     father of China’s aerospace”.

Qian was     7    (extreme) knowledgeable, especially in the area of frontier science research.     8     might have made him so outstanding and creative was probably his extensive interests. His deep     9    (appreciate) for art often gave him inspiration in his scientific research. The whole country     10    (sad) by Qian’s death in 2009 and people honoured and remembered him in different ways.

At age 5，Lin Qiaozhi lost her mother，    1     death affected her deeply. So at age 18, she decided to study medicine despite     2     (complain) from her brother. After graduating from Peking Union Medical College with the Wenhai Scholarship, the     3     (high) prize given to     4     (graduate), she     5     (hire) as a resident physician in the OB-GYN department of the PUMC Hospital and later was named     6     chief resident physician. Several years later, she was sent to study in Europe and then the US where she was invited to stay by her colleagues but she     7     (reject) their offer.

In1941, Lin Qiaozhi became the first Chinese woman ever     8     (appoint) director of the OB-GYN department of the PUMC Hospital. In1954, she was elected to the first National People's Congress. However, despite all these important positions, she was more interested in tending patients,     9     (publish) medical research on care for women and children, and training the next generation of doctors. Though Lin Qiaozhi never married, she was known     10     the “mother of ten thousand babies", having delivered over 50,000 babies in her lifetime.

Yuan Longping, known as the “father of hybrid rice”, was born in 1930.     1     (learn) that farmers often had poor harvests and sometimes even had a serious     2     (short) of food to eat, he chose to study agriculture and graduated from Southwest Agricultural College in 1953.

Since his graduation, Yuan     3     (devote) his life to finding ways to produce more rice. Through constant effort, he overcame enormous technical difficulties     4     (develop) the first hybrid rice     5     could be used for farming in 1974. This hybrid enabled farmers to expand their output     6     (great).

Today,     7     is estimated that about 60 percent of domestic rice consumption in China is comprised     8     crops come from Yuan’s hybrid strains. Yuan’s innovation has helped feed not just China, but many other     9     (country) that depend on rice as well.

Though Yuan’s hybrid have made him quite     10     (wealth), he doesn’t lead a life of leisure. Instead, he donates much money to support agricultural research.

Tu Youyou has become the first Chinese scientist     1     (award) a Nobel Prize for her discovery of qinghaosu,     2     makes malaria patients across the world more likely to survive.

After studying medicine at university, Tu acquired     3     good knowledge of both traditional Chinese medicine and Western medicine through further training courses, which led to her success in her discovery of qinghaosu.     4     (face) with the serious situation of malaria, as the head of a team intended to find a cure for the disease, Tu and her team referred to the ancient books of traditional Chinese medicine, and tried countless times to make extract from different herbs     5     they managed to make qinghao extract that could treat malaria in mice. However, due to the     6     (short) of research resources and good equipment, it was hard to produce enough qinghao extract for large trials. Tu and her team didn’t give up. They tried almost all means to solve the problems they faced. Fortunately, their efforts finally paid     7    . They     8     (success) in isolating the most effective part of the extract and named it qinghaosu, which is now a key part of many malaria medicines.

When     9     (give) her Nobel Lecture, Tu encouraged scientists to further explore the treasure house of traditional Chinese medicine and raise it to a     10     (high) level.

Chinese agronomist (农业科学家) Yuan Longping, the “father of hybrid rice (杂交水稻)”, died of an illness at 1:07 p.m. on Saturday at the age of 91.

    1     a serious nationwide starvation (饥荒) in the 1960s,Yuan,decided to devote     2     (he)to studying how to increase the production of rice, the main food of China. Yuan     3     (succeed) in developing the world's first high-yielding hybrid rice in 1973,     4     production could reach over 500kg per mu. For the following years, he continued to develop hybrid rice, achieving     5     (increase) higher outputs than before. On September 29, 2019, Yuan     6     (award) the “Medal of the Republic”, the highest honor in the country, for his outstanding     7     (contribute) to China's agricultural development and food supply. In 2020, hybrid rice     8     (develop) by Yuan’s team achieved a new world record.

Yuan once said he had two dreams: one was to “enjoy the cool breeze under rice crops     9     (tall) than men,” and the other was that “hybrid rice could be grown all over     10     world to help solve global food shortage.

Professor Yuan’s devotion to China and the world will inspire us to value food and try our best to serve our country.

Yuan Longping was born in 1930.Since he graduated from Southwest Agricultural College in 1953,he    1    (devote)his life to finding ways    2    (grow)more and more rice.As a young man, he saw the great need for increasing the rice output. At that time    3    (hungry)was a serious problem in many parts of the countryside. Yuan searched     4     a way to increase rice harvests without     5    (expand) the areas of the fields.In 1950,Chinese farmers could produce about 56 million tons of rice.In    6    recent harvest,however,nearly 200 million tons of rice were produced.These increased harvests mean that 22% of the world’s people    7    (feed)from just 7% of the farmland in the world.Yuan LongPing is now circulating his knowledge in India and many other less    8    (develop)countries to increase their rice harvests.    9    (thank)to his research,the UN is trying to rid the world    10    hunger.Using his hybrid rice,farmers are producing harvests twice as large as before.

“Father of hybrid rice” Yuan Longping     1       ( pass) away at 13:07 pm in Changsha of Hunan province, Xinhua reported     2    Saturday. Yuan Longping(1930-2021) was a pioneer for all people. Although he was one of China's most famous    3    (science), Yuan Longping considered     4     ( he) a farmer.Indeed,his sunburnt face and arms and his slim,strong body were just like those of millions of Chinese farmers,for whom he had struggled for decades. Dr Yuan Longping developed super hybrid rice. In 1974,he became    5     first agricultural pioneer in the world    6    ( grow) rice with a high output.Now more than 60% of the rice     7    (produce) in China each year is from this hybrid strain.

In 1949, Yuan applied for Southwest Agricultural College and began his special     8     (connect) with rice--a staple food of the Chinese people that would become the focus of his lifelong research career.

Now the focus of Yuan's hybrid rice project    9     ( change) from increasing output to green and sustainable development     10      is strong and tall enough.The second dream is that the whole world can plant the rice he developed and all the people in the world  are not hungry.

Let's remember the great man.

Tu Youyou is universally acknowledged as a scientist of great     1    (achieve). Born in Ningbo, China, on 30 December 1930, Tu Youyou graduated from Peking University Medical School in 1955. In 1967, she was chosen for a research team     2     was formed by the government with the aim of discovering a new treatment     3     malaria and two years later she became the head of the project in Beijing. She and her teammates examined over 2,000 old medical texts,     4    (evaluate) 280,000 plants for their medical properties, and tested 380 distinct ancient Chinese medical treatments that showed promise in the fight against malaria. As a     5    (commit) and patient scientist, she never acknowledged defeat whatever difficulty she met. After failing to draw out useful extract by     6    (boil) the sweet wormwood, she began even     7    (careful) thinking and research work. She drew     8     conclusion that boiling the sweet wormwood     9    (destroy) its medical properties. So she used a lower temperature     10    (draw) out the extract and finally she succeeded.
