This means that there is a lot that can go wrong when you run. Most sports have some kind of running or jumping So experts at many shoe companies work hard to design good sport shoes. First, a designer enters a plan for a shoe into a computer .Engineers then improve the design. A second computer designs a model for the shoe. Then a few pairs are made. Next, the shoe is tested. Different kinds of sports shoes are made for different uses. Some are made to help marathon  runners save energy during a race. Some are made for the stop-and-go kind of running tennis players. But all sport shoes have one thing in common: they are designed to help people's feet comfortable during sports. Today, nearly every sport has its own special shoe designed for just the kind of running that sport needs. Question: Different kinds of sport shoes   _  . - are made in different shoe companies - are designed for people of the different weight - are of the same price - meet the needs of different sportsmen

Article: Chinese scientist Tu Youyou on October 5 won the Nobel Prize in physiology or medicine amongst a trio for discovering parasite therapies . 85-year-old Tu is awarded this world-renowned prize for her contribution to reducing the death rate of malaria, minimizing patients' suffering and promoting mankind's health. This is what science is all about. Tu's finding has saved millions' lives during the 40 years. This also proves the value of her research product. The reward is never too late in that aspect. The moment of joy and satisfaction came when she discovered the artemisinin( ) after all kinds of failures in experiments. As the first Chinese mainland Nobel Prize Winner of natural science award, Tu's winning completely surprised Chinese people, who have long been wondering when the first Chinese Nobel laureate in natural science would appear. Let's backtrack to 40 years ago. Tu accomplished the breakthrough findings without access to any advanced equipment, communication with outside world and papers to research. However, over the 40 years, improvements and innovations have transformed everything. Nowadays, Chinese scientists have the passion to invent. As Premiere Li Keqiang mentioned in his letter, "Tu's winning the prize signifies China's prosperity and progress in scientific and technological field". Tu's record-breaking winning serves as a reminder to those who are too eager for instant success. Science is never about instant success. There is no way to measure how much you spend on scientific research and compare it with how much reward you get. Question: Which of the following statements is TRUE according to the passage? - Science is just about the cure of the disease for mankind. - Tu is the first Chinese to win the Nobel Prize of natural science award. - Tu's achievements tell us that victory doesn't come in one day. - Tu made the breakthrough in discovering the artemisinin with advanced technology.
Tu's achievements tell us that victory doesn't come in one day.

Read the following article and select the best answer. Article: When people search online, they leave a trail that remains stored on the central computers of firms such as Google, Yahoo and Microsoft. Analyzing what we're looking for on the Web can offer a remarkable understanding of our anxieties and enthusiasms. UK writer John Battelle wrote on his blog, "This can tell us extraordinary things about who we are and what we want as a culture." Google's experimental service Google Trends, for example, compares the numbers of people searching for different words and phrases from 2004 to the present. According to these graphs, sometimes people's interests are driven obviously by the latest news: when the Spice Girls, a pop group, announce a reunion, there's an immediate rush to find out more about them. Other results are strikingly seasonal: people go shopping online for coats in winter and sandals  in summer. The most fascinating possibility is that search data might help predict behavior. Perhaps we search for a political candidate's name when we are thinking about voting for him or her. This information could clearly be useful to a marketer - it's already how Google decides which ads to show on its search results pages - or to a political campaign manager. Marissa Mayer, a Google vice-president, argues that Google Trends correctly "predicted" George Bush's victory over John Kerry in the 2004 election. The graph clearly shows that Bush continued his lead over Kerry, in terms of search volumes, even when polls  suggested  _ . However, that's not always the case. For instance, the same approach predicted Hillary Clinton would beat Barack Obama in the race for the Democratic presidential nomination in 2008 turned out to be wrong in the end. Question: The search data can help foresee the following EXCEPT   _ - the different features of different cultures - the better place to put advertisements in - the victory of a politician in the election - the reunion of a pop group
the reunion of a pop group

Read the following article and select the best answer. Article: Most academics would view a post at an elite university like Oxford or Harvard as the crowning achievement of a career--bringing both honour and access to better wine cellars. But scholars desire such places for reasons beyond glory. They believe perching on one of the topmost branches of the academic tree will also improve the quality of their work, by bringing them together with other geniuses with whom they can collaborate and who may help spark new ideas. This sounds reasonable. Unfortunately,as Albert Laszlo Barabasi of Northeastern University,in Boston (and also, it must be said, of Harvard), shows in a study published in Scientific Reports, it is not true. Dr Barabasi and his team examined the careers of physicists who began publishing between 1950 and 1980 and continued to do so for at least 20 years. They ranked the impact of the institutions these people attended by counting the number of citations each institution's papers received within five years of publication. By tracking the association of individual physicists and counting their citations in a similar way, Dr Barabasi was able to work out whether moving from a low to a high-ranking university improved a physicist's impact. In total, he and his team analysed 2,725 careers. They found that, though an average physicist moved once or twice during his career, moving from a low-rank university to an elite one did not increase his scientific impact. Going in the opposite direction, however, did have a small negative influence. The consequence is that elite university do not,at least as far as physicists are concerned,add value to output. That surprising conclusion is one which the authorities in countries such as Britain, who are seeking to concentrate expensive subjects such as physics in fewer, more elite institutions--partly to save money, but also to create what are seen as centers of excellence--might wish to consider. Question: Which of the following is true of Dr Barabasi's research? - It proved that a post at an elite university helps academics. - It began in 1950 and ended in 1980. - It calculated the citations of the physicists' institutions. - It is based on a lot more than 2,000 scholars of various fields.
