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.

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.

9 . NATURE has many ways of reminding us who is in charge. Her most deadly weapons — bacteria, viruses, and parasites (寄生虫) —claim millions of lives every year.

But thanks to the hard work of great scientists, mankind could turn nature against itself. And it is for exactly this sort of work that the Royal Swedish Academy of Sciences awarded the 2015 Nobel Prize in Physiology or Medicine on Oct 5.

Half of the prize was awarded to the Irish William Campbell and the Japanese Satoshi Ōmura for discovering avermectin (阿维菌素), a drug that kills the parasitic worms that cause river blindness and lymphatic filariasis (象皮病). Chinese scientist Tu Youyou shared the other half of the prize for developing Artemisinin, a drug that helps kill the parasite that causes malaria.

Ōmura is a microbiologist by training. He studied Streptomyces bacteria to find compounds (化合物) that work against harmful microbes (微生物). Campbell, working in the US, took bacteria found by Ōmura and took out avermectin, which is effective against parasites in farm animals. An improved type of avermectin was later produced for humans, which greatly reduced the cases of river blindness and lymphatic filariasis.

Avermectin comes from bacteria, but artemisinin comes from plants. Its discovery was the result of Project 523, a Chinese government project to find a new malaria drug in the late 1960s.

Malaria is a mosquito-borne disease caused by parasites, which attack red blood cells, causing fever, and sometimes, brain damage and death. Tu and her team made 380 herbal extracts from 2,000 recipes from traditional Chinese medical books. In 1971, after more than 190 failures, Tu’s team finally found an extract that was 100 percent effective against malaria parasites. It was called qinghaosu, later renamed artemisinin. In 2001, the World Health Organization named artemisinin the first choice in the treatment of malaria.

Millions of people are still troubled by infections caused by parasites. But the WHO said that by 2013, malaria deaths had fallen by 47 percent compared with 2000. Similarly, river blindness used to be one of the leading causes of preventable blindness. These days, doctors are talking about chances of wiping the disease off Earth. All of these achievements would not be possible at all without the drugs that Campbell, Ōmura and Tu helped to discover.

1. The drug Tu Youyou developed, artemisinin, has proven effective in treating ______.

A．river blindness

B．malaria

C．lymphatic filariasis

D．infections caused by Streptomyces bacteria

2. Avermectin, discovered by Campbell and Ōmura, comes from ______.

A．bacteria

B．plants

C．farm animals

D．ocean animals

3. Which of the following is TRUE about the discovery of artemisinin?

A．It took Tu and her team about 10 years to discover artemisinin.

B．Tu and her team achieved success after about 380 failures.

C．Artemisinin has saved millions of people’s lives since its discovery.

D．Artemisinin was discovered thanks to the efforts of scientists from at home and abroad.

10 . Huang Danian, the well-known Chinese geophysicist, was born in 1958 in Guangxi, China. As a keen and able student, Huang went to the UK in 1993 to further his studies.

By the time Huang moved back to China in 2008, he had been living and working in the UK for 15 years. He had a good job and a life there, but he gave it all up to return to home driven by the idea that he needed to contribute to his country. As one of the world’s leading experts in deep earth exploration technology, Huang was invited to participate in the “Thousand Talent” programme. He took up a position at Jilin University, Changchun.

Huang was named lead scientist on China’s deep earth exploration programme, developing advanced cameras that can see through the Earth’s crust(外壳) so that it can be analysed without having to dig into it. He set up an advanced lab, sometimes paying for equipment with his own money. Some described him as a “lunatic” (a “madman”), but this passion(热情) and drive enabled Huang to push forwards China’s deep earth exploration technology into a world-leading position. Huang’s devotion contributed to China’s lunar probe(月球探测器) Yutu being landed on the moon in 2013 and the launch of the spacecrafts Shenzhou-11 and Tiangong-2 in 2016.

Huang's health also paid the price for his commitment to his work. He began having fainting fits(昏厥) in 2012, but paid them little attention, stating he did not have time to go to see a doctor——his work always came first. In November 2016, Huang fainted and was taken to hospital, where he was diagnosed with cancer. The disease was so advanced that he had just a couple of months to live.

Like the true scientist he was, Huang never gave up, but always tried to push forwards. Even from his hospital bed, he continued his work, writing letters of reference for his colleagues and replying to questions from his students. Huang died in January 2017, aged just 58. More than 800 people attended his funeral to celebrate a life that burned so bright, but was so short.

1. Huang returned to China in 2008 because ________.

A．he desired to devote himself to his motherland	B．the “Thousand Talent” program attracted him
C．Jilin University offered him a top position	D．he wasn’t satisfied with the life in the UK

2. What is Paragraph 3 mainly about?

A．China’s aerospace development.	B．Huang’s working attitude and style.
C．China’s deep earth exploration technology.	D．Huang’s great contributions to China.

3. What can we learn from the last two paragraphs?

A．The working environment caused Huang’s disease.

B．Huang worked continuously despite his poor health.

C．Huang was taken to hospital after he fainted in 2012.

D．A large sum of money was paid to treat Huang’s illness.

4. Which of the following can be used to describe Huang Danian?

A．Generous and honest.	B．Hardworking and determined.
C．Modest and courageous.	D．Passionate and patient.
