Research has become both simpler and more complex. It's simpler because,{#blank#}1{#/blank#} you have computer, you can find information you need by searching the Internet. For all you information, you don't have to go to {#blank#}2{#/blank#}library to find the relevant resource and take notes on it. Instead, you can find some sources from the Internet{#blank#}3{#/blank#}print the copies needed. Remember, however, that you should usually consult different types of sources. That is, you {#blank#}4{#/blank#}always rely just on the Internet for you research.

    While finding information is easier than ever, at the same time, researching has become {#blank#}5{#/blank#} complex. There is a lot more material available, which means you may be overwhelmed {#blank#}6{#/blank#}the amount of information. You need to learn {#blank#}7{#/blank#} to sort through and find the relevant information for your particular project. Also,{#blank#}8{#/blank#} need to check the accuracy of it.

    What do you read when you travelling by train? What about other passengers? Perhaps a woman{#blank#}1{#/blank#}(sit) near you is reading a romantic novel. A man is reading a serious biography about a politician. And there's a student reading an English textbook.

    What do their{#blank#}2{#/blank#}(choice) say about them? Do you judge them by{#blank#}3{#/blank#}they reading? I have to tell you that your impressions of them may be{#blank#}4{#/blank#}(complete) wrong. The woman reading the romantic novel could be a {#blank#}5{#/blank#}(law). She just wants a light read to take her mind off work. The man reading the biography wants you{#blank#}6{#/blank#}(consider) him knowledgeable, and he is just {#blank#}7{#/blank#}(show)off. The student reading the textbook isn't a student at all. She's an English teacher.

    Publishers know people are {#blank#}8{#/blank#} (concern)about what they read on public transport and put out different versions (版本) of a cover For example, books about Harry Potter have an{#blank#}9{#/blank#} (interest)cover for young readers and then another more serious version for adults.

    So next time you see what other people are reading on a train don't jump to any conclusions.

    Here is a situation {#blank#}10{#/blank#} you could say, "Don't judge a book by its cover.”

    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.
