My feelings about science have{#blank#}1{#/blank#} (complete) changed. More than one science teachers at my new school {#blank#}2{#/blank#} excellent and {#blank#}3{#/blank#} (friend) . The science{#blank#}4{#/blank#} (facility) are very good with laboratories that have all the{#blank#}5{#/blank#} (late) equipment. Our chemistry teacher takes us to public science lectures about four times{#blank#}6{#/blank#} term, {#blank#}7{#/blank#} are always interesting, because the lecturers are famous at their area of science. In the last 20 years, seven Canadian scientists{#blank#}8{#/blank#} (win) the Nobel Prize. Now{#blank#}9{#/blank#} I'm becoming more and more interested in is physics and I want to study it at university. But my parents are {#blank#}10{#/blank#} (astonish), as they always thought I would become an English teacher.

    In the 17th century, dentists did their best {#blank#}1{#/blank#} (make) false teeth. The problem, however, was not making the teeth, {#blank#}2{#/blank#} was keeping them in place. They had to tie each tooth to the one on either side of it. Only rich people could afford false teeth, {#blank#}3{#/blank#} were usually made of gold or silver. As more and more people wanted new teeth, poor people {#blank#}4{#/blank#} (sell) their teeth to the rich so that they could buy food and clothing. During the next 200 years, many changes were made to false teeth although some of these were not really improvements. Towards the end of the 19th century, for example, cheap elastic teeth were introduced. But they caught fire very {#blank#}5{#/blank#} (easy), and a number of men were badly burned when their teeth caught fire while they were smoking {#blank#}6{#/blank#} (cigarette). Nowadays, false teeth {#blank#}7{#/blank#} (be) so well made and look so real that it is often {#blank#}8{#/blank#} (possible) to tell from a person's appearance whether or not they have them. And in {#blank#}9{#/blank#} near future, very few people will have them by {#blank#}10{#/blank#} (add) certain things to the water we drink, we have been able to keep our teeth so healthy that most people will never need false teeth.

    Nowadays more and more people like to travel, {#blank#}1{#/blank#} (especial) when vacations come.A great number of people rush out of their homes or companies to {#blank#}2{#/blank#} (travel) spots. They either drive or take a bus, a train, a ship {#blank#}3{#/blank#} so on. Some even ride bikes.

    However, there {#blank#}4{#/blank#} (be) another way of travelling—poorism. People have a tour in {#blank#}5{#/blank#} poorest areas of the worlds Some people may take a one-day poorest tour, and some even pay to stay in very poor neighborhoods {#blank#}6{#/blank#} (experience) the lowest living standards in the worlds Poorism tours take place around the world, and not just in the third world {#blank#}7{#/blank#} (country).You can, for instance, tour New York neighborhoods in the Bronx. Such tours can take people into the heart of poor areas. These tours may awaken people to pay {#blank#}8{#/blank#} (much) attention to long-standing poverty, or the effects of war.

    Some think that tours in the poor areas can raise social care. And the money from the tour can {#blank#}9{#/blank#} (donate) to help the people {#blank#}10{#/blank#} live there.

Tu Youyou, a {#blank#}1{#/blank#}(commit) and patient scientist, was born in China and graduated from Peking University Medical School in 1955. After graduation, she worked at the China Academy of Traditional Chinese Medicine in Beijing. In 1967, she {#blank#}2{#/blank#} (choose) by the government to join a team of scientists with the aim of discovering a new treatment {#blank#}3{#/blank#} malaria. Her team examined over 2,000 old medical texts, and evaluated 280,000 plants for their medical {#blank#}4{#/blank#}(property). From their research, they discovered and tested 380 distinct ancient Chinese medical treatments that showed promise in the fight against malaria.

After a lot of failures, in 1971, Tu Youyou and her team members succeeded by using a lower temperature {#blank#}5{#/blank#}(draw) out the extract. They even insisted on testing the medicine on {#blank#}6{#/blank#}(they) to make sure that it was safe. Later, the medicine was tested on malaria patients，most of whom recovered. The medicine,{#blank#}7{#/blank#}was called artemisinin, soon became a standard treatment for malaria.

According to Tu Youyou, the discovery of artemisinin was a team effort. Upon {#blank#}8{#/blank#}(hear) that she had been awarded {#blank#}9{#/blank#}Nobel Prize, she said the honour belongs to the team behind her and all the people of her country. The success{#blank#}10{#/blank#}(prove) the great value of traditional Chinese medicine.
