Introducción a la Lectura Comprensiva de Inglés Académico para Medicina Veterinaria 

FICHA TEÓRICO-PRÁCTICA #8: 

TIEMPOS VERBALES 

En un curso de lectura comprensiva, la idea de presentar la formación de los tiempos verbales es sólo para reconocimiento 

de los mismos en los textos. 

El siguiente cuadro muestra, de manera muy sintética y a través de ejemplos, cómo se forman los tiempos verbales 

llamados simple en inglés, en sus formas afirmativa, negativa e interrogativa.

calves), bite size values calculated indirectly from estimated herbage intake and total daily bites were different. 

 

 

 

Zoby y Holmes informaron que, con extremas diferencias en tamaño del animal, (vacas maduras vs vacas en 

engorde vs terneros) los valores del tamaño del mordisco, calculados indirectamente a partir de la ingesta de 

hierba y los mordiscos diarios, eran diferentes.

LISTA DE VERBOS IRREGULARES 

¿Cómo utilizarla 

La columna INFINITIVE nos da el nombre del verbo, es decir el verbo sin conjugar en ningún tiempo verbal; de esta 

columna formamos el simple present agregándole “s” o “es” para las terceras personas del singular (he, she, it). 

La columna SIMPLE PAST nos informa acerca de los verbos irregulares en simple past (pretéritos perfecto e indefinido del 

español), y la forma que se presenta es la misma para todos los pronombres. No figuran aquí los verbos regulares, porque 

su simple past se forma agregando “ed” al infinitivo. 

La columna PAST PARTICIPLE nos informa acerca del pasado participio (terminación –ado -ido del español) de los verbos 

irregulares; una vez más, no figuran aquí los verbos regulares porque su pasado participio se forma agregando “ed” al 

infinitivo. 

Comúnmente se llama “primera columna” a la INFINITIVE, “segunda columna” a la SIMPLE PAST, y “tercera columna” a la 

PAST PARTICIPLE.

Texto 1: 

Staphylococcus aureus causes both acute and chronic mastitis that responds poorly to treatment. It is easily 

transmitted at milking time and colonizes the teat canal but, contrary to prior opinion, does not colonize the skin. 

1. Observá el Texto 1 e identificá todos los verbos y frases verbales en simple present. Encerrálos con un 

círculo en el texto mismo. 

2. Leé el texto 1 y pensá en un título para este breve texto que responda a la pregunta ¿de qué trata 

TÍTULO 

TEXTO 1: 

Texto 2: 

This program is the national udder health program for the Australian dairy industry. More than $130 million is lost to 

Australian dairy farmers each year through poor udder health. Mastitis is the major cause of this loss. Mastitis 

reduces milk yield and leads to poor quality milk. Together, these factors erode the milk income received by farmers. 

In addition, antibiotic therapy used to overcome udder disease adds to dairy farmers’ costs and require strict 

monitoring to prevent residue entering the milk. This program plan consists of a set of recommendations to assist 

dairy farmers with profitable control of mastitis.

Reproductive Organs and Breeding Pattern 

There are two ovaries in the cow: one on the right and one on the left side, which produce the egg or ova and the 

female sex hormone, estrogen. At each estrus, a blister-like structure, called a follicle, enlarges and ruptures 

approximately 14 hours after the end of heat. This ruptured follicle releases the egg and the funnel of the oviduct picks 

it up. It is here that the sperm cell and egg unite to form the embryo which develops into the calf. The embryo enters 

the uterus four days after breeding and secretions from the uterus nourish it until 35 days when the membranes of the 

embryo and uterus unite to complete implantation. There are two oviducts and two uterine horns plus a single cervix 

which is about two or three inches long and one inch in diameter. The cervix is cartilaginous and hard tissue with three 

well developed rings on the inner lining and forms an effective seal during pregnancy. The cervix opens up or dilates 

during heat so sperm can pass to the uterus and an insemination tube can be inserted during and shortly after estrus. 

The vagina forms a passageway from the outside vulva to the cervix where the semen is deposited during natural 

service. The vulva is seen from the outside and increases in vascularity and size during heat.


Texto 5: 

The body is divided by four basic planes. The median plane divides the body into equal right and left halves. Sagittal 

planes are any planes that lie parallel to the median plane. Sagittal planes divide extremities longitudinally into 

medial and lateral aspects. The midsagittal plane and the median plane are synonymous. The dorsal plane divides 

the animal into dorsal and ventral portions. Last, the transverse plane intersects the body perpendicular to the body’s 

axis, dividing the trunk of the animal into cranial and causal regions. An extremity is also considered to have its own 

axis; therefore, a transverse plane of a limb divides the limb into distal (distant) and proximal (close) portions.

HOW TO GIVE YOUR DOG MEDICATION Fuente: www.vetstreet.com 25 de agosto de 2011 

There will be times when you need to give your dog medication — and that can be a tricky task, especially if you’ve never 

done it before or if he is uncooperative. Here is expert advice on how to get the medicine down. 

To get your dog to take his medicine, you may have to employ a few sneaky tactics, whether the medicine comes in a pill, a 

capsule or is liquid. Luckily, there are a few simple things you can try to help you keep your pet still so you can give him the 

medication that will make him feel better. But first you must be clear on what the veterinarian recommends. 

1. Understanding the Medication Instructions: When your veterinarian prescribes a new medication, make sure you 

completely understand the instructions before you leave the office. She will likely explain the route of medication into the 

dog (by mouth, into the ears, or into the eyes, for example) how often the medication should be taken (once daily, every 12 

hours, etc.), duration of treatment (7 days, until gone), and other special considerations (give with food, follow with water). 

You should also ask how you can expect your pet to respond to the treatment—and how quickly he will be feeling better. 

Some medications don’t have very strict dosing instructions—for example, your veterinarian may simply say you should 

administer the drug as needed. Other times, you may be able to give a medication once a day even though the package 

says twice a day. But since dosing guidelines must be followed precisely, you should always ask your veterinarian before 

making adjustments. And don’t hesitate to speak up if the dosing instructions don’t work with your schedule—in some cases 

your veterinarian may be able to recommend another medication that can be given on a different timetable. For example, if 

your work schedule does not permit dosing every 8 hours, your veterinarian may be able to recommend a medication that 

can be given less frequently. 

To make sure you don’t forget any doses, consider making a medication schedule for your pet. Simply write the date and 

time that the medication needs to be administered, along with the last day of treatment. Even if your dog is feeling better, 

you should still give him the medication for the correct length of time. The reason: Complications can occur if antibiotics 

aren’t given for the full duration of recommended treatment, plus some medications—such as corticosteroids—will cause 

illness if they’re discontinued. 

You should also take care to follow all label directions exactly, since seemingly minor factors, like improper storage (for 

example, keeping a refrigerated medication at room temperature) can affect a medicine’s safety and effectiveness. And if 

your pet experiences any side effects after taking the medication, contact your veterinarian promptly before making any 

changes to your dog’s dosing schedule or discontinuing the medication. 

2. Administering Pills: It can take some trial and error to get your dog to swallow a pill. When your veterinarian 

prescribes a medication, ask if it can be given with food, as some dogs take pills very readily if they’re hidden inside a treat


(such as liverwurst, a small piece of soft cheese, peanut butter, or cream cheese) or given with a small amount of canned 

food (simply crush pills or break and empty capsules and mix into the food.) The downsides to this method: Your dog must 

eat all of the food in one sitting (to ensure he receives the full dose), plus some coated pills and capsules have a bitter taste 

if the capsule or coating is removed, and if the medication makes the food taste bad, your dog may refuse to eat it. You will 

probably know after the first or second dosing if this method will work. 

It’s a bit more challenging if you must give your dog a pill directly by mouth. If your dog isn’t used to having your hands 

around his mouth, gradually introduce him to this by stroking his muzzle and chin for a few moments to calm him down. If 

you think your dog may try to bite you, do not attempt giving him medicine by mouth—ask your veterinarian about 

alternative medication options. But if you trust that your dog won’t attempt to harm you, try these tips to make it a bit 

easier (warning: this technique takes practice and may require more than one attempt to get your dog to swallow the pill): 

Stand/kneel beside your dog (on his right side if you are right-handed). Hold the pill between the thumb and index 

finger of your right hand if you are right 

handed. Switch it if you are left handed. 

Using your left hand, reach over the top of your dog’s nose and squeeze your thumb and middle finger between his 

upper and lower teeth. Your thumb 

should be on one side of your dog’s mouth and your middle finger on the other side. Try to stay behind the canine 

teeth (the long, pointy teeth near the 

front of the mouth). If you’re doing this properly, the sides of the upper lip will curl in as your fingers go in his 

mouth. 

Once your fingers are inside, gently tilt your dog’s head back to encourage him to open his mouth. 

Once the mouth is open, use your right index finger and thumb to place the pill near the base of the tongue. Then 

remove your hands quickly so your dog 

can swallow. 

Rub your dog’s throat lightly and offer a small amount of water to encourage swallowing. 

3. Administering Liquid Medication: Some people prefer liquid medication because administering it doesn’t require 

placing your fingers inside your dog’s mouth. Here are tips for administering liquid medication: 

Draw the medication into the dropper or syringe and hold it in your right hand (if you’re right handed). 

Stand/kneel beside your dog (on his right side if you are right-handed). Place your left hand behind your dog’s 

head to stabilize it. You can gently stroke the back of the head to distract your dog. 

Using your right hand, insert the tip of the dropper or syringe into the side of your dog’s mouth. Try to stay close 

to the back of the mouth (near the molars) and away from the canine teeth (near the front of the mouth). 

Once the tip is in, empty the medication into the mouth and release your dog’s head. Rub your dog’s throat lightly 

to encourage swallowing. 

4. Troubleshooting Tips: If you’re unable to administer medications to your dog, consider these expert tips: 

Ask for help. If your dog won’t cooperate with receiving medication, ask someone to help you restrain your dog while you 

control the head and give the medication. 

Don’t risk injury. If you’re unable to administer medication or are worried your dog will hurt you, call your veterinarian 

and ask for advice. Seek out a different formulation. Some medications are available in several forms, including pills, liquid 

given by mouth with an eye dropper or syringe, chewable flavored treats, and transdermal gels (the gel is applied to your 

dog’s skin, where it’s absorbed into the bloodstream). So if you dog won’t swallow liquid medication or if the pill just isn’t 

working out, ask your veterinarian if there is another option. 

Consider calling in the pros. Some veterinarians can arrange daily outpatient appointments for a technician or assistant 

to administer your dog’s medication. If your schedule doesn’t permit this, some veterinarians may be able to board your dog 

so that medication can be given until the course of treatment has been completed. 

Hopefully giving your dog medication will go smoothly but if it doesn’t, or if you are concerned about dosage or anything at 

all, call your veterinarian.

1 Glove Barriers to Bacterial Cross-Examination Between Hands to Food (fragmento adaptado) 

Glove use has recently become popular in foodservice establishments because of the intuitive assumption that 

a physical barrier will prevent the food handler from contaminating food. Food handling and poor handwashing 

practices have traditionally been the source of foodborne disease outbreaks. However, some have argued that 

5 mandatory glove use can cause overall hygiene to decline and that gloves are not commonly properly used. In 

September 1999, the Food and Drug Administration asked the National Advisory Committee for the Microbial 

Criteria for Foods to examine this issue. The committee determined that there were insufficient data on gloves to 

mandate their use in the model food code. 

The majority of the glove effectiveness originates from the healthcare literature. These studies have limited 

10 foodservice application because they evaluate surgical gloves that typically are of a better quality than foodservice 

gloves. 

Some studies have examined gloves in a foodservice setting, focusing primarily on attachment characteristics 

and contamination on the outer part of the glove. In a study by Bardell, droplets of saliva containing herpes 

simplex virus were placed on the outside of latex disposable gloves and touched to lettuce or ham at 0, 30, and 

15 60 min. The virus was isolated from the food in all five trials for each group. Fendler et al. asked volunteers to 

handle ground beef containing Escherichia coli and showed that the outside of the glove was highly contaminated 

at the end of a 3-h period regardless of whether the handlers had changed gloves or washed their hands. Other 

studies also provide data on the transfer of bacteria and viruses from hand to kitchen surfaces, hands to food, 

and the survival of organisms on these surfaces. 

20 The primary objective of this study was to determine four bacterial transfer rates: chicken to bare hands, 

chicken to hands through gloves, bare hands to lettuce, and hands to lettuce through gloves. A secondary 

objective was to fit the transfer data to statistical distributions so they could be incorporated in a quantitative risk 

assessment.

1 Management of an enterprise in agriculture, horticulture and forestry has to take into account a wide range of 

issues: the management of soils, crops and animals, the selection and use of machinery and implements, 

marketing arrangements, man management, and local and world commodity prices. Except for subsistence 

farming, where security of food supplies is all important, the purpose is to make the enterprise profitable. 

5 The objective of soil management is to create suitable conditions for the crops that are to be grown. Soil is 

required to provide anchorage and the physical and chemical conditions required by the plant. What the farmer 

does to help meet these requirements depends on what crops he grows, the required yield, the inputs that are 

available to him, and the soil and climatic conditions. 

Management of the soil started with the first farmers. Cultivations, rotations and irrigation are ancient 

10 practices. In the past 200 years there have been several innovations: farm machinery has become more powerful, 

crop varieties have been bred that give higher yields, and fertilizers and chemicals for the control of pests have 

been introduced. 

Soil is the growers´ main resource and it is in their interests to maintain it in as fertile a condition as possible. 

In this they are usually successful, but there has been, and still are, examples of bad management. Erosion has 

15 been caused by cutting down trees, salts have accumulated in soils under irrigation, and unsuitable soils have been 

brought into cultivation.
