<\/span><\/h2>\n\n\n\nIn our daily speech and in rough drafts, we tend to rely heavily on the various forms of the verb to be<\/em>.<\/p>\n\n\n\nThe verb to be <\/em>is unlike any other verb because it is inert–that is, it doesn’t show any action. For example, in the sentence “The researcher is a professor at Duke” the verb is merely connects the subject with what grammarians call the subject complement. We could just as easily say “The professor at Duke is a researcher” without changing the meaning of the sentence.<\/p>\n\n\n\nIt would be nearly impossible to draft documents without some linking verbs. Because you diminish the vigor of a document by using an excessive number of is<\/em> and are<\/em> constructions, you should try to limit their frequency. Finally, note that the progressive form of a linking verb\u2014which involves using to be as an auxiliary verb with a participle–is much more acceptable. The advantage of the progressive form is that it illustrates action progressing over time, enabling us to shape concise sentences that indicate something is currently happening: “The coauthors are disagreeing about the order in which their names should be listed when the book is published.”<\/p>\n\n\n\nIt is<\/em> and there are<\/em> constructions often lead to sluggish, passive sentences, so you should limit their frequency, as illustrated below.<\/p>\n\n\n\nSample<\/strong>: While it is<\/em><\/strong> crucial for us to speak out on behalf of education<\/em><\/strong>, it is<\/em><\/strong> important that we do so in a manner consistent with statute and administrative rules<\/em><\/strong>.<\/p>\n\n\n\nRevision<\/strong>: We need to speak out on behalf of education while<\/em><\/strong> observing statute and administrative rules<\/em><\/strong>.<\/p>\n\n\n\nSample<\/strong>: According to the certification theory<\/em><\/strong>,
