Keep only the material that is strictly relevant to your own ideas.
So here you would not want to quote the middle sentence, since it is repeated again in the more informative last sentence.
Finally, you should always consult your instructor to determine the form of citation appropriate for your paper.
You can save a lot of time and energy simply by asking "How should I cite my sources," or "What style of citation should I use? In the following sections, we will take you step-by-step through some general guidelines for citing sources.
If your sources are very important to your ideas, you should mention the author and work in a sentence that introduces your citation.
If, however, you are only citing the source to make a minor point, you may consider using parenthetical references, footnotes, or endnotes.Taking the exact words from an original source is called quoting.You should quote material when you believe the way the original author expresses an idea is the most effective means of communicating the point you want to make.In the forty-ninth segment of the text, entitled “A Stuffed Swan,” he writes: Using all of his remaining strength, he tried to write his autobiography. This was due to his still lingering sense of pride and skepticism...After finishing “A Fool's Life,” he accidentally discovered a suffered swan in a used goods store.If you want to borrow an idea from an author, but do not need his or her exact words, you should try paraphrasing instead of quoting.Most of the time, paraphrasing and summarizing your sources is sufficient (but remember that you still have to cite them! If you think it’s important to quote something, an excellent rule of thumb is that for every line you quote, you should have at least two lines analyzing it.For example, If you have already introduced the author and work from which you are citing, and you are obviously referring to the same work, you probably don't need to mention them again.However, if you have cited other sources and then go back to one you had cited earlier, it is a good idea to mention at least the author's name again (and the work if you have referred to more than one by this author) to avoid confusion.But often you can just tag this information onto the beginning or end of a sentence.For example, the following sentence puts information about the author and work before the quotation: Milan Kundera, in his book The Art of the Novel, suggests that “if the novel should really disappear, it will do so not because it has exhausted its powers but because it exists in a world grown alien to it.” You may also want to describe the author(s) if they are not famous, or if you have reason to believe your reader does not know them.
