3、rn in Ningbo, China, on 30 December 1930, and graduated from Peking University Medical School in 1955. After she graduated, she worked at the China Academy of Traditional Chinese Medicine in Beijing. In 1967, the Chinese government formed a team of scientists with the objective of 9._(discover) a ne
4、w treatment for malaria, and Tu Youyou was among the first researchers 10_(choose). In the beginning, Tu Youyou went to Hainan, 11_ malaria was more common, to study malaria patients. In 1969, she became the head of the project in Beijing, and decided to review ancient Chinese medical texts12_(find)
5、 traditional botanical treatments for the disease. Her team examined over 2, 000 old medical texts, and evaluated 280, 000 plants for their medical properties13(翻译)_. From their research, they discovered and tested 380 distinct ancient Chinese medical treatments that showed promise14翻译)_ in the figh
6、t against malaria.One medical text from the fourth century suggested 15_(use) the extract from sweet wormwood to treat 16_ fever. Tus team tested a collection of dried wormwood 17_(leaf) but found no effect. They then tried boiling fresh wormwood, and using the liquid 18_(obtain) from this to treat
7、malaria, but this did not work19(翻译)_ either. Their project got 20_(stick). However, Tu Youyou would not acknowledge defeat. She analysed the medical texts again, and 21_ chance, she found one sentence 22_(suggest) a different way to treat the wormwood. She concluded that23_(boil) the sweet wormwood
8、 apparently destroyed its medical properties. 24_(use) a lower temperature to draw out25(翻译)_ the extract, she found a substance that worked. After 26_(fail) more than 190 times, the team finally 27_(success) in 1971. Tu Youyou and her team members even insisted on 28_(test) the medicine on themselv
9、es to make sure that it was safe. Later, the medicine was tested on malaria patients, most of 29_ recovered. This medicine，30_ was called artemisinin, soon became a standard treatment for malaria.According to Tu Youyou, the discovery of artemisinin was a team effort. Upon 31_(hear) that she had been
10、 awarded the Nobel Prize, she said, “The honour is not just 32_(me) There is a team behind me, and all the people of my country. This success proves the great value of traditional Chinese medicine. It is indeed an honour for Chinas scientific research and Chinese medicine to be spread around the wor

He made numerous 4_(contrite) to the world, the most well-known being the general theory of relativity an
12、d the famous formula E=mc2. Einstein was not only a genius; he was a 5_(courage) and kind figure loved by many people.This gentle genius 6_was born in Germany on 14 March 1879. When he was 16, he tried to enter university in Switzerland, but failed due to his low scores in the general part of the en
13、trance exam, despite 7_(obtain) exceptional scores in maths and physics. After studying for another year, he managed to pass the exam, entering university in 1896 and graduating in 1900.After two years of 8_(look) for work 9_a teacher, Einstein took a job as a clerk in the Swiss patent office. While
14、 working there, 10out of翻译_ a strong passion for knowledge, he continued to study, 11_(earn) a doctorate in physics in 1905. That same year, 12_ was later recorded as a miracle year in science, he published four extraordinary physics papers. Following this, he gradually became famous throughout the
15、world 13_ the new Isaac Newton. After four years, he was able to quit his job at the patent office and enter research full-time at a university. In 1922, he was awarded the 1921 Nobel Prize for Physics for his explanation of the photoelectric effect.Circumstances changed in 1933, 14_ Hitler came to
16、power in Germany. Einstein, 15_ was Jewish, found the doors of academic institutions 16_(close) to him. As 17_ consequence, he had to flee Germany. After 18_(spend) time in Europe, he finally took up a position as a researcher at the Institute for Advanced Study in Princeton, USA. Following that, he
17、 continued to make great 19_(achieve) in physics and mathematics.To the public, he was seen as a 20_(slight) odd-looking but kind and funny man. He had a thick moustache and long white hair, 21_ sometimes stood on end as though he had just received an electric shock. Although he was a genius, he som

There is even a story about 23_ he helped a little girl 24_ knocked on his door and asked for help with her homework. In fact, Einstein often encountered people on the street25
19、_ would stop him and ask him to help explain things. After many such occasions, he finally started saying, “Pardon me! Sorry! Always I am mistaken26_ Professor Einstein!”On 18 April 1955, it was reported that Einstein had 27passed away翻译_, and the whole world mourned the great loss of a brilliant sc

These smart homes will keep us secure, save us energy, and provide 4_(一个更舒适的居住环境).Intelligent ControlsToday, we have to use 5._( 开关) for our lights, knobs for o
22、ur appliances, and remote controls for our TVs and air conditioners. In the future, we will be using 6_(先进) technology every day for automatic control of just about everything in our home. The future home will use integrated sensors to tell when you leave home each morning, and then go into an 7_(节能
23、模式) all by itself. You will no longer have to think about turning switches on and off yourself.

Your lights will come on10_(一) you enter the door along with your favourite
24、music or TV programmes, and you will find your dinner already 11_(prepare) for you.
