      Activity 11  
      Write a summary and paraphrase of the following statements.
- Original text: Writing a summary
 
Academic writing builds on the works of others.  A chemist investigating a new, inexpensive  way to produce hydrogen as an alternative fuel to gasoline will refer to  earlier research in order to help readers understand the context of her present  research.  An economist analyzing the  impact of increasing the minimum wage will refer to earlier analyses in order  to establish comparisons.  Each time you  write a research paper, you refer to the work of others in an effort to blend  ideas and information in a single, coherent discussion.  Before using sources in your own work, you  must understand them.  And the most  direct way to express your understanding is to write a summary—a brief, objective  restatement of the source in your own words.

2. Original text: Academic Argument Defined
        Academic writers use argument as a tool for understanding how the  world works or ought to work and how we attach meaning to our actions and  creations.  Within the university, an  argument is undertaken less as an expression of disagreement than as an effort  to build knowledge.  Researchers—your  instructors included—make observations and present findings as written  arguments to be published in journals or delivered to colleagues at  conferences.  They know as they write  that others may raise challenges and that, when challenged, they themselves  will respond. Through this process of argument and counterargument, researchers  build knowledge and make decisions.

3. Original text: Analysis
        An analysis is an argument in which you study the parts of  something to understand what it is made of, how it works, what it means, what  its problems may be, or why it might be significant.  In academic settings, researchers analyze  every subject imaginable: from cliff diving to sculpture, from the birth of  galaxies to blood flow, from the courtship behavior of orangutans to the  emigration patterns of Monarch butterflies. In each case the researcher uses an  analytical tool: With it, you can examine the skin cells from the back of your  hand and see details invisible to the naked eye.  But change the tool—use an x-ray machine, for  instance—and you will see something else entirely.
