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.

    No one could say that Katy Perry is an ordinary artist. Her songs are not just about sweet love and heartbreaks,{#blank#}1{#/blank#}usually have bigger themes. Take the songs Firework (2010) and Roar(2013) for example,{#blank#}2{#/blank#}Perry sings about being our own master and{#blank#}3{#/blank#}(discover) our true value. Earlier this year, she {#blank#}4{#/blank#} (announce) her new album (专辑) Witness, together with a new idea for W music Perry calls her new style “purpose pop”, meaning a{#blank#}5{#/blank#}(society) and political message. It seems that Perry has become tired{#blank#}6{#/blank#} simply encouraging people. Now, she wants to educate them politically as well. The best example of Perry's purposeful pop is{#blank#}7{#/blank#} (probable) the song Chained to the Rhythm, in which Perry criticizes the {#blank#}8{#/blank#} (behave) that people are unwilling to think more critically (批判的) about the world.

    But when it comes to the concept (概念) of purposeful pop, it is, in fact, something a lot of pop stars have been doing for a while. For example, Beyonce's 2016 song Formation deals with various problems such as an {#blank#}9{#/blank#} (argue) between white policemen and black citizens (公民) in the US,{#blank#}10{#/blank#} (hope) to create change through music.
