William Campbell, Satoshi Omura and Tu Youyou jointly won the 2015 Nobel Prize for medicine{#blank#}1{#/blank#} their work against parasitic diseases (寄生虫病). 85-year-old Tu was awarded this prize for her contribution to{#blank#}2{#/blank#} (reduce) the death rate of malaria (疟疾), minimizing patients' suffering and promoting mankind's health. This is {#blank#}3{#/blank#} science is all about.

    As a matter of fact, Tu has won some attention when she {#blank#}4{#/blank#} (get) the Lasker Award in 2011. But there is no way to compare her popularity back to the attention she is receiving today. As the first Chinese mainland Nobel Prize Winner of natural science award, Tu's winning {#blank#}5{#/blank#} (complete) surprised Chinese people, {#blank#}6{#/blank#} have long been wondering when the first Chinese Nobel Laureate in natural science would appear.

    Tu Youyou is the first Chinese scientist to win a Nobel Prize for work {#blank#}7{#/blank#} (carry) out within China. She has spent 40 years' time on scientific research. Although the Nobel Prize did not come to her until four decades later, it is definitely one of {#blank#}8{#/blank#} most privilege rewards that recognizes Tu's devotion and perseverance in discovering artemisinin (青蒿素). Her record-breaking winning  {#blank#}9{#/blank#} (be) a reminder that science is never about instant success. There is no way to measure how much you spend on scientific research and compare {#blank#}10{#/blank#} with how much reward you get.

    Parkour（跑酷）is a sport which trains people to deal with any physical obstacles in their path. It is not a competition but a physical training. A person joining in parkour is called traceur. Traceurs run along a path and use only their bodies to deal with the obstacles in the most efficient way. Parkour pays more attention to efficiency{#blank#}1{#/blank#}(make) it different from the similar practice of free running. Parkour{#blank#}2{#/blank#}(common) includes running, jumping, climbing, rolling and other similar types of physical movements. Many teenagers think that parkour is quite {#blank#}3{#/blank#} cool sport. They have great interest in it.

    The {#blank#}4{#/blank#}(invent) of parkour can't {#blank#}5{#/blank#}(give) to one person because many people have worked on it. A French officer developed the earlier form of parkour. The term “parkour” was first introduced by David Belle and Sebastiar Foucan in the early 1980s{#blank#}6{#/blank#} that time, they were two teenagers. This sport {#blank#}7{#/blank#}(become) more popular in the1990s when many films were made on it.

    {#blank#}8{#/blank#} makes parkour different from other sports is its power to bring people together. It allows traceurs to forget the {#blank#}9{#/blank#}(society) and other problems, and makes a large group work and grow together instead of competing with each other. People can benefit from parkour as it can make them stronger. Still, it also influences one's thought process by improving self-confidence and critical-thinking skills. In this way, parkour allows one to deal with {#blank#}10{#/blank#}(difficulty) in daily life if he or she deals with them through parkour.

    How should you behave when you meet someone {#blank#}1{#/blank#}the first time? An American shakes your hand {#blank#}2{#/blank#} (firm) while looking you straight in the eye. In many parts of Asia, there is no physical contact at all. In Japan, you should bow, and the {#blank#}3{#/blank#} (much) respect you want to show, the deeper you should bow. In Thailand, people greet each other by pressing both hands together at the chest. In both countries, eye contact {#blank#}4{#/blank#}(avoid) as a sign of respect.

    In Spain, lunch is often {#blank#}5{#/blank#}biggest meal of the day, and can last two or three hours. For this reason, many people eat a light breakfast and a late dinner. In Mexico, lunch is a time {#blank#}6{#/blank#} (relax), and many people prefer not to discuss business as they eat. In Britain, it's not unusual to have a business meeting over breakfast.

    In most countries, an exchange of business cards{#blank#}7{#/blank#} (be)necessary for all introductions. You should include your company name and your position. If you are going to a country {#blank#}8{#/blank#} your language is not widely spoken, you can get the back side of your card {#blank#}9{#/blank#} (print) in the local language. In a word, when {#blank#}10{#/blank#} (travel) abroad, we should follow local habits.

    I've always been attracted by the {#blank#}1{#/blank#} (beautiful) of Chinese culture and its vast history. When we first arrived in China, my friend Tony and I expected a huge city {#blank#}2{#/blank#} (fill) with modern buildings, busy streets and a crowded transport system. But we were pleasantly surprised.

    The first thing {#blank#}3{#/blank#} struck us was the space. Yes, Beijing is indeed huge, but its wide streets and green spaces made every area feel less crowded. Tian'anmen Square was the perfect example of this. The Forbidden City was {#blank#}4{#/blank#} (surprise) clean and well preserved. Everywhere we looked, there were people {#blank#}5{#/blank#} (tidy) and cleaning, which really left an {#blank#}6{#/blank#} (impress) of national pride. We {#blank#}7{#/blank#} (concern) that few people would speak English, even in Beijing. But we found it common for Chinese people to know a few words of English. The most exciting part of our visit was riding around in the sunshine and exploring the city {#blank#}8{#/blank#} Ofo bikes.

    It was great {#blank#}9{#/blank#} (experience) Beijing's landmarks in person after admiring {#blank#}10{#/blank#} for so many years. This was our first visit to China, but certainly not our last.

Barbara Millicent Roberts, also called Barbie, {#blank#}1{#/blank#} (consider) the most successful toy doll in history. She first {#blank#}2{#/blank#} (appear) in the world of toys about 60 years ago, and has become very popular among little girls.

According to the Mattel Company, {#blank#}3{#/blank#} created Barbie, 90% of all American girls between 3 and 10 have at least one Barbie at home. However, today there are many dolls competing {#blank#}4{#/blank#} Barbie on the market. Bratz dolls, for example, look more like today's pop {#blank#}5{#/blank#} (star) with lots of makeup and miniskirts. Now Bratz is {#blank#}6{#/blank#} great challenge to Barbie, as the company offers various clothing, too.

It seems that Barbie is no longer {#blank#}7{#/blank#} (attract) to older girls. "For younger girls, playing with a Barbie is much fun, but when they get older, they want something more fashionable and modern," says a shop keeper of a toy store in New York. On the international scene, Barbie remains number one. Although Mattel has been selling fewer Barbies in the United States over the past years, sales in other countries have kept {#blank#}8{#/blank#} (rise). It is hard {#blank#}9{#/blank#} (say) how long Barbie will stay on as a celebrity in the world of toy dolls, but {#blank#}10{#/blank#} (undoubted) 60 is not the age to retire.
