An Introduction to Irregular Verbs in English

An Introduction to Irregular Verbs in English Although fewer than 200 verbs are classified as irregular, these include some of the most common words in English. Here, after briefly reviewing regular verbs, well look at the principal parts of irregular verbs. Review of Regular Verbs Regular verbs have three basic forms: the present (or base form), the past (ending in -ed), and the past participle (also ending in -ed). These three forms are referred to as the principal parts of a verb. Heres how we might list the principal parts of the regular verb laugh: I always laugh at her jokes. (present)She laughed nervously during her speech. (past)We have often laughed together. (past participle) The past participle form works with different auxiliary verbs (has or have; had) to form different tenses. (See Forming the Past Tense of Regular Verbs.) What Are Irregular Verbs? Irregular verbs are those verbs that do not end in -ed in the past tense. Though their endings differ from those of regular verbs, irregular verbs rely on the same auxiliary verbs (also called helping verbs) to indicate past, present, and future time. Principal Parts of Irregular Verbs Irregular verbs have three principal parts: I tell a joke. (present)I told a joke. (past)I have told a joke. (past participle) Some irregular verbs, such as tell, have the same form in the past and the past participle. Others, however, have different forms: I wear a cap. (present)I wore a cap. (past)I have worn a cap. (past participle) With irregular verbs such as wear, we need to learn the different forms for the past and the past participle. Auxiliaries with Irregular Verbs Just like regular verbs, irregular verbs are used with various auxiliaries to form different tenses. For instance, we use has or have with the past participle of an irregular verb to form the present-perfect tense: Tom has worn out his welcome. Similarly, we use had with the past participle of an irregular verb to form the past perfect tense: I had never worn a seat belt before you told me why I should. And we use will with the present form of an irregular verb to form the future tense: I will wear a seat belt from now on. In short, irregular verbs work the same way as regular verbs; they just have different endings. Tables of Irregular Verbs The tables linked below contain the most common irregular verbs in English. Although you are probably familiar with many of them already, study the verbs in all three lists and look for patterns that will help you remember the forms of all these verbs.

Free Essays on The Great Gatsby Jay

The greatness of an individual can be defined in terms far beyond tangible accomplishments. In F. Scott Fitzgerald’s classic American novel, The Great Gatsby, Jay Gatsby’s greatness comes from his need to experience success and his will to achieve his dreams. Nick Carraway narrates the story, and his cousin, Daisy Buchanan, is Gatsby’s love. Daisy, however, is married to Tom Buchanan, a wealthy, arrogant womanizer who despises Gatsby. Gatsby feels the need to be successful and wealthy, and his participation in a bootlegging operation allows him to acquire the wealth and social status needed to attract Daisy. In his narration, Nick focuses on Gatsby’s fixation of Daisy and how he longs for her presence in his life. Gatsby’s greatness comes from his power to dream, his competence in turning dreams into reality, and his absolute love for Daisy. In The Great Gatsby, Jay Gatsby uses his dreams as motivation for his existence. Fitzgerald uses wealth and social status to define Gatsby’s character, which is exemplified by his lavish parties and the dignitaries who attend them. In his formative years, Gatsby was employed by a wealthy yachtsman, Dan Cody. It is from Cody that Gatsby develops his appreciation for wealth. â€Å"To young Gatz, resting on his oars, looking up at the railed deck, that yacht represented all the beauty and glamour in the world† (Fitzgerald 106). Fitzgerald uses this quote to mark the point at which Gatsby encounters wealth and power for the first time, and also, he uses it to symbolize Gatsby’s social standing and economic status. By comparing Gatsby’s rowboat with the luxurious yacht of Cody’s, Fitzgerald presents the idea that money and power translate into bigger and better things. The event is symbolic in that it illustrates Gatsby’s perception that wealth is a necessity. By saying that he was â€Å"looking up† to â€Å"all the beauty and glamour in the world,† Fitzgerald make...

The vulnerabilities of industrial control systems and possible Essay

The vulnerabilities of industrial control systems and possible solutions - Essay Example Industrial control systems (ICS) are imperative to the quality of life that most of society shares and depends on every day. These systems regulate the electricity, food supply, medical and chemical manufacturing, as well as many other processes and utilities that are used daily.After September 11, 2001, the threat of terrorist attacks became a high priority on the home front (Marsh 2006). Most people worried about airplanes, metro or subway systems, or bombs, but a few realized that with the computerization of control systems in a variety of industries becoming normal operating procedures, the risk of attack was just as possible as any other probable target. In fact, some of the systems, such as nuclear plants or chemical manufacturing companies, were more apt to be targeted than others. This concern led to the National Institute of Standards and Technology (NIST) to lead a 500 member forum to discuss cyber-security of the ICS regulating our lives and our country.At the conclusion o f this 2004 forum, NIST produced the System Protection Profile-Industrial Control Systems (SPP-ICS) to use as guidelines and strategies to find the vulnerabilities in each facility and possible solutions. Some of the main concerns include terrorists and unfriendly governments, human error, disgruntled employees, bored teenagers, and natural disasters to name a few. However, most facilities looked only on the outside, without considering errors on the inside that could do as much damage as those external forces. (Barr, 2004; D'Amico, 2004; Marsh, 2006; NIST, 2004; NIST's process control, 2004; Wagman, 2008). NISTS findings were based on the System Target of Evaluation and all risks and vulnerabilities are determined by this standard. The corporate leaders should look at and consider the vulnerabilities and their solutions to help identify the areas that are in need of immediate attention in their own facilities and to make the cyber-connection of the location secure. Unfortunately some do not believe there is a real threat. For example, Tom Donahue from the CIA stated that "attacks on critical infrastructure lack the necessary dramatic display that seems to be preferred by this constituency" (Marsh, 2006, p. 12). This concept may have been true five years ago, but as the world becomes more connected the disruption of electricity, water, or gas would be a fairly dramatic event for those experiencing it, and for those watching it. Previously most facilities were separated by using their privately owned machines, hardware and methods of communication. However, with the onset of more facilities and corporations using "commercial, off-the-shelf" products the vulnerability increases (D'Amico, 2004). The SPP-ICS provides three main areas to watch; the type of agent, method of attack, and the asset that will be affected by the attack. The agent is the insider or outsider that either maliciously or accidently causes an attack on the ICS. The vulnerabilities of attack can include, but are not limited to, protocols, unnecessary systems attached to the ICS, outside remote access to the ICS, incorrect IT architecture, lack of security controls, and lack of risk assessment upon or prior to installation of the system. The assets consist of all the systems used to control the system software and hardware and the infrastructure of the company (Barr, 2004; NIST, 2004) When working to correct or strengthen the security of these systems, the company should look at physical items, the connectivity and if it is secure, authentication, backup and remote access as well as many other attributes of security.
