How to Teach the Present Perfect for ESL Students

The present perfect is one of the most difficult tenses to learn for students. Teaching the present perfect effectively involves making sure students understand that the present perfect in English is always connected in some way to the present moment in time. Many languages including French, German, Spanish and Italian use the present perfect for past events. The present perfect in English covers what happens from a past moment to the present moment in time. Establishing this connection in students minds early will help students avoid mistakes. It helps to divide usage into three major areas: 1) From the past until now: Ive lived in New York for twenty years. 2) Life experience: Ive visited every state in the country. 3) Recent past events that influence the present moment: Ive just had lunch. Start by Speaking about Your Experiences Introduce the present perfect by providing three short situations One about life experiences, one speaking about some things that started in the past and continue into the present. Finally, also illustrate the present perfect for events that influence the present moment in time. Speak about yourself, your family or your friends. Life Experience: Ive visited many countries in Europe. Ive been to Germany and France a few times. My wife has also been in Europe quite a lot. However, our daughter has never visited.Past to Present: My friend Tom has a number of hobbies. Hes played chess for more than fifteen years. Hes surfed since he was a little boy, and hes practiced the art of the Japanese tea ceremony since September.Recent Events that Influence the Present:  Wheres Pete? I think hes gone to lunch, but hes been away for about ten minutes. I know hes been to the bank this afternoon so hes probably decided he needs a nice meal.  Ask students about the differences in these forms. Once the differences have been understood, return to your short scenarios and ask students related questions using the present perfect.Life Experience: Ive visited many countries in Europe. Which countries have you visited? Have you ever been to XYZ?Past to Present: My friend Tom has a number of hobbies. Hes played chess for more th an fifteen years. Which hobbies do you have? How long have you done them?Recent Events that Influence the Present:  What have we just studied? Have you understood the form? Explaining the Present Perfect Using the verbs youve introduced, quickly ask students the infinitive form for each verb. (i.e. Which verb is gone? - go, Which verb is bought? - buy, etc.). After having studied the past simple, students should recognize that many past verbs in -ed whereas others have irregular forms. Introduce the past participle form use in the present perfect. Its a good idea to provide an irregular verb sheet for future reference. Use three timelines showing the differences between usages: life experience, past to present, and recent events. At this point in the curriculum, students should easily be able to switch between positive, negative and question forms. However, its important to point out that questions in the present perfect are most often formed with How long for past to present usage, and Have you ever..? for life experiences. Finally, for present perfect that affects the present moment, its important that students understand the differences between the time expressions just, yet and already as well as for and since for past to present. Comprehension Activities Each of these uses of the present perfect can be practiced through present perfect role plays and reading comprehension activities. Its also a good idea to compare and contrast time expressions used for the present perfect and past simple. Present perfect worksheets and quizzes focusing on differences asking students to choose between the present perfect or the past simple will also help. To practice switching between the present perfect and the simple past practice short conversations with Have you ever...? followed by a question asking for specifics with when, or where. Have you ever been to France? - Yes, I have.When did you go there?Have you bought a car? - Yes, I haveWhen did you buy one? Challenges with the Present Perfect Common challenges with the present perfect include: Use of present perfect for events that happened in the pastSwitching between present perfect and past simple fluidlyUse of yet and already in questions, negative and positive formsUse of since with dates and for with periods of time

Italian Renissance and the Reformation - 1005 Words

The Renaissance and Reformation were two very important periods of time in European history that included change in culture and religion. The Renaissance happened before the reformation. The Renaissance was the rebirth of art, literature, and architecture. The reformation focused mainly on reforming the Catholic Church from its evil ways. Out of the Catholic Church came the protestant church. There were many different characteristics of the Renaissance. The main one is that society had a secular, or worldly, view. This can be proved by how their art was changed. They stopped painting religious things and painted the human body. Other main points are that recovery from the Black Plague and decline of church power led to interest†¦show more content†¦John Calvin was another leader in the Protestant church. He was originally Catholic and switched to Protestantism. He agreed with Luther on most things but put more emphasis on the â€Å"power, grace, and glory of God.† He believed in predestination. A belief that God determines in advance who is saved and who is to be damned. This religion would be called Calvinism, named after the founder. He also began the Reformation in Geneva, Switzerland. His reform was that there would be government inside the church, but the church would not rule the government. Another religion that broke off was the Anabapt ists. They were radicals who disliked the power given to the state through the reformation. They believed in spiritual rebirth in adulthood. They also believed that all believers were equal and that there was a complete separation of church and state. They had no political authority over them and were not allowed to bear arms. The Church of England broke away from the Catholic Church because Henry VIII wanted an annulment which the Catholic Church would not give him. Therefore he broke off and made the act of supremacy. It said that the king was taken, accepted, and reputed as supreme head of the Church of England. The start of the Catholic reformation was because of the spread of Protestantism.

Question: Taking into account the role of the myelin sheath and the nodes of Ranvier, explain how APs are propagated along an axon, in a healthy subject, and how this is changed in MS. Answer: Nervous System The axons of neurons often are myelinated i.e. they are wrapped around by a sheath of myelin. Myelin is a protein-lipid complex, which is formed by Schwan Cells of in the Central Nervous System when they wrap their membrane around the axon, eventually locked together by a membrane protein, P0. Nodes of Ranvier are the portions of the axon that are not being enveloped by the myelin i.e. these about 1m periodic gaps of separated by 1mm are unmyelinated. Myelin acts as insulation to nerve impulse conduction. Nerve impulses are sent between neurons which is the only mode of communication for the nervous system. Electronic potentials that can produce propagated disturbances are called action potentials or nerve impulses. The nerve impulses are produced due to change in ionic conduction across the cell membrane of the neurons. The potential of nerve cells are found to be negative inside relative to outside; it is about -70mV. When the neuron is stimulated a series of potential changes occu r across its membrane and the stimulus thus propagates through the axon to another adjacent neuron. Depolarization increases the membrane potential to +35mV and again reverses and falls rapidly causing to reach the resting depolarized state. In unmyelinated nerve fibres local circuits of ion current are produced in the active regions of the neuron which is stimulated; the local circuit thus produced can depolarize the adjacent part of the membrane which continues in s sequential fashion (Arancibia-Carcamo Attwell, 2014). Conversely, in myelinated neurons ion exchange is allowed only at the Nodes of Ranvier and rest of the axon is insulated by myelin itself. This increases the speed of transmission of impulse through the axon. When an impulse reaches a Node of Ranvier it cannot flow through the high-resistance myelin sheath instead depolarizes the membrane at the next Node of Ranvier about 1mm away from it. Thus myelin increases the length constant i.e. the distance an ion travels before leaking out of the membrane by increasing the membrane resistance and thus resulting in insulation of the neuron. Further myelin decreases the capacitance of the membrane by separating the opposite charges across the two sides of the mem brane by a considerable distance. Thus in myelinated neurons impulse flows in a jumping fashion from one Node to the next which is termed as Saltatory Conduction. Multiple Sclerosis is an idiopathic, autoimmune, inflammatory disorder of the Central Nervous System that causes patchy destruction of the myelin sheath of the neurons. The destruction of the myelin sheath results in delayed or blocked conduction of impulses through the affected neurons leading to several neurodegenerative symptoms. Further the damage of myelin causes patches of scar tissues at various regions of the Brain and Spinal Cord and hence the name Multiple Sclerosis (Scleroses meaning scar tissue) (Dendrou, Fugger Friese, 2015). The impairment of nerve impulse conduction can affect physiological functions such as movement, speech or sight. Diagnosis at early stages of the disease prognosis is very difficult which causes delay in commencement of treatment. Endocrine System Metabolism is one of the most significant physiological processes necessary for the sustenance if life. Each and every cell of the human body undergoes various levels of metabolism to perform the fundamental bodily functions. Thyroid gland plays a key role in this context by regulating the level of metabolism in the cells required for the optimal functioning of the same. The hormones secreted by the thyroid gland are Thyroxine (T4) and triiodothyronine (T4), which primarily regulates the oxygen consumption of cells, lipid and carbohydrate metabolism, thermogenesis, growth and nervous system development. Thus they play a pivotal role in growth and maturity and deregulation of the hormone levels can lead to severe disorders. Hence, the hormone secretion is intensely regulated to maintain normal body functioning. Thyroid stimulating hormone or Thyrotropin secreted from the anterior pituitary regulates the secretion of the thyroid gland. It is a tropic hormone and secretion of Thyrotropi n in turn is regulated by Thyrotropin releasing hormone secreted from the paraventricular nucleus of the hypothalamus. Circulating thyroid hormones have feedback effects at hypothalamic and pituitary levels thus completing the Hypothalamus pituitary thyroid axis to maintain optimum levels of both the thyroid hormones in circulating blood (Ortiga?Carvalho, Chiamolera, Pazos?Moura Wondisford, 2016). Increased secretion and hence occurrence of thyroid hormones in the circulating blood results in decreased secretion of Thyrotropin and Thyrotropin releasing hormone and the opposite occurs when thyroid hormones levels are low in circulating blood. Thyroid hormones levels are maintained at a very narrow range by the three glands, failure of any of them causes excess or too less production of thyroid hormones resulting in hyperthyroidism or hypothyroidism respectively. However, the state of normal functioning of the thyroid gland is known as euthyroidism. Hypothyroidism, generally called Myxedema in adults can be caused by a number of diseases of the thyroid gland or can be secondary effects of pituitary gland or hypothalamus dysfunction. In case of pituitary hypothyroidism and hypothalamic hypothyroidism the patient responds to a dose of Thyroid stimulating hormone or Thyroxin; but in can of thyroid gland dysfunction no response to Thyroxin is obtained (Pearce et al., 2013). Symptoms of hypothyroidism may include markedly decreased basal metabolic rate, coarse and sparse hair, dry and yellow skin and low tolerance of cold. Hyperthyroidism is more common in women than in men and is often caused by self-antibodies that stimulate the receptor for thyroid hormones. This results in non-functioning of thyroid hormone in spite of being present in the circulating blood. Both the thyroid hormone secretion are substantially increased and due to over activity of the thyroid gland, it gets enlarged leading to a condition called Goitre (Biondi et al., 2015). However, as thyroid hormone levels remain adequate in the circulating blood Thyroid stimulating hormone is maintained at a low level due to feedback inhibition of the same. Some of the significant symptoms of hyperthyroidism are weight loss, low tolerance of heat, increased blood pressure, and a markedly increase in the basal metabolic rate of the body.

Wall Street Barbarians At The Gate Essays -

Wall Street: Barbarians At The Gate Barbarians at the Gate is a story of the largest takeover in Wall Street history. Ross Johnson turned CEO of a company, which was the product of three merged companies, Standard Brands, RJ Reynolds, and National Biscuit Company (Nabisco). The newly formed companys, called RJR Nabisco, stock began to fall and never recover. Johnson along with Shearson executives planned a leverage buyout (LBO), in which a brokerage firm (Shearson) would borrow money from banks and buy up all the outstanding shares from the stockholders to turn the company private. The problem with this is that the company would be put into jeopardy of other companies that can outbid the parent company, which would lead to a takeover. The higher the bid would lead to a bigger debt and lesser profits for the owners of the firm. One of the six accounting principles that was discussed in the book was the expense principle, which helps determine performance of a company by measuring the outflows and inflows of resources. The matching principle guides the recognition of expenses, so good matching will ultimately lead to a better measure of performance. When KKR exercised due diligence of RJR Reynolds, they could not figure out other uses of cash in the statements obtained. The initial projections they had obtained from RJR Nabisco was a heading other uses of cash. Beside it was a row of figures stretching out ten years, each year ranging from 300 to 500 million dollars. Was it cash flowing in or out? Should he add it? Subtract it? Ignore it? (Barbarians 369). Obviously, KKR was trying to figure out whether RJR Nabisco was a good investment or not. The debt accrued by an LBO needed to be paid off using cash from the company acquired. The difference between expensing the millions of dollars or recognizing it as r evenues would mean a bid of 92 or 96 dollars per share. The expense recognition method here proved to be helpful for KKR to acquire RJR Nabisco. Economics Essays

Management Technique - Assignment Example 30) The most important asset of the airport was the choosing a suitable baggage handling system .The application of the automatic baggage handling system facilitated quick aircraft turnaround time to as minimal as 30 minutes. The efficiencies in the operations were mostly promoted by the occurrence of a fast turn around and this made it remain competitive among other aircrafts. The plan however faced some shortcomings because of the under estimation of the complexity of the project that resulted to problems like snowballing and public frustrations from the individual involved. Notably, the airport’s opening had been delayed for at least 16 months due to problems in the baggage system. Another setback was the increased expenditure to cater for the maintenance of the empty airport and also the city of Denver was charged an interest cost of $ 1.1 M daily during the time of the delay (Jean 2000, p. 28) However the most embracing moment of the delay occurred after the media had sho wcased a demonstration on the system which clearly showed how the system bags were crushed, vital information and goods destroyed as well as how two carts crashed into each other while moving at a very high speed. After everything had been resolved and the opening day was agreed upon .The plan by this time had been destroyed beyond control and the system had been distorted completely. The system was now only using one single concourse by the single airline and for only out bound fights in comparison to the 3 concourses it had been using in the automating baggage system. The rest of the baggage handling was carried out by the use of a simple conveyor belts with a manual tug and a quickly built trolley system when it was as ascertained that the automating system could not work efficiently again. After a period of 10 years, the remaining parts of the system were still used in the baggage handling until the United Airlines announced that the old system was to be abandoned completely in August 2005.This was due to the increased cost of maintenance that had risen to about $ 1 million per month even surpassing the cost of a manual tug and trolley in a month (Adam 2000, p. 5) Basic Mode of Failure The downfall of the plan can be attributed to many factors. They include the fact that some of the main minds behind the formulation of this plan underestimated its complexity and this is seen to be the main reason for the failure of the Denver International Airport project. The managers of the project set up the most complex baggage system that has never been applied before. The increasing of the size of the plan by as much as ten times more than the automated system made it more difficult to control or grow in potential. This led to the rise of issues like â€Å"line balancing† due to the complexity of the system (Marj 2005, p 7). In a measure to regulate the system delivery, empty carts were distributed around the airport ready to pick up new bags. To achieve this goal all the 100 pick-up points had to be allocated empty carts efficiently. However this move got a setback because the queue could not clearly tell where they should anticipate the empty carts and where they should wait for the new bag. This resulted into delays thus the system could not efficiently achieve their operational goals as targeted. The project was initiated late because the managers under estimated its comp
