II. Read the following passage and then circle the correct answer

Passage 1

There are many causes of headaches, and most people suffer them at some time or other. Although doctors have come a long way from the old days, when headaches were ascribed to evil spirits and treatments ranged from cutting our part of the skull to concoctions of cow brain and goat dung, they are still not sure what sets off headaches.

The most significant advance has been the acceptance that they are not the result of emotional stress. Until recently, many doctors thought that imbalances in the body’s systems were to blame, but experts now believe it is the brain itself. They point to malfunctioning chemicals, such as serotonin, whose job it is to send messages to regulate the contraction and dilation of blood vessels in the brain.

Monosodium glutamate, a flavor enhancer used in Chinese cooking, can cause headaches in some people, as do many other common foods. Red wine, aged cheese, coffee, chocolate, nuts, and preserved meats contain nitrates, caffeine, and tyramine, chemicals that may produce pounding headaches.

Even though the exact culprit has yet to be found, there are plenty of treatments for prevention or cure. Over-the-counter preparations such as aspirin are fine for treating the occasional headache, but often exacerbate severe cases. Beta blockers, usually used for lowering blood pressure, seem to head off migraines. Antidepressants are effective, too. But doctors also recommend non-drug treatments such as relaxation techniques, which can be used in combination with medication, and diet modification, to cut out foods that cause attacks.

A. Praying to spirits.

B. Sacrificing cows and goats.

C. Operating on the patient’s head.

D. Writing prescriptions.

Passage 2

Whether one is awake or asleep, the brain emits electrical waves. During wakefulness, the waves are recorded at about ten small waves per second. With the onset of sleep, the waves become larger and slower. The largest, slowest waves occur during the first three hours of sleep. Mental activity slows down but does not stop. In fact, if awakened from slow-wave sleep, a person can often remember vague thoughts that occurred during that period of sleep.

During sleep, intervals of small, fast waves also occur. These waves are similar to those experienced while awake. The eyes move rapidly, and it appears to the observer that the sleeper is watching some event. Sleepers who are awakened during this rapid-eye-movement sleep will often recall the details of dreams they have been having. Sleep of this kind is called dreaming sleep or rapid-eye-movement sleep, also known as REM sleep.

In a period of eight hours, most sleepers experience from three to five instances of REM sleep. Each instance lasts from five to thirty minutes with an interval of at least ninety minutes between each one. Later instances of REM sleep are usually of longer duration than are instances earlier in the eight-hour period.

People who suffer sleep deprivation experience fatigue, irritability, and loss of concentration. Sleep is essential because it regenerates the brain and the nervous system. Slow-wave sleep may be especially helpful in restoring muscle control, whereas REM sleep may be more important in revitalizing mental activity. It appears that both kinds of sleep are necessary, and the recuperation of sleep of one kind will not compensate for a lack of the other kind of sleep.

B. Can stay up all night working and recover the sleep they need bysleeping for a few hours the next afternoon
C. Need REM sleep to restore mental functioning
D. Do not need as much sleep because of the heighened brain wavesinvolves in creative activity

Passage 3

As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and “life in the fast lane” have long been known to contribute to 5 the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.

Heart failure, for example, appears to have seasonal and temporal 10 patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since 15 discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.

In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more 25 at risk for heart attacks than their married counterparts.

Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.

Passage 5

There are some diseases for which we know no cure. For many of these, however, scientists have been able to discover a means of prevention. Smallpox is such a disease.

In the 18th century, millions of people died of smallpox, while many others who recovered from the disease was left scarred for life. Today, it is rare to find a case at all.

By 1780, doctors had noticed that once a person had smallpox, he became immune to it. From this observation, the theory of inoculation was developed. Inoculation is a way of deliberately giving a person a disease by placing diseased mattar under the skin. When this is done, the person may develop a mild case of the disease, but from then one he is safe from a several attack.

Using this principle, an English doctor named Edward Jenner set to work against smallpox. He found that persons who had had a milder disease called cowpox could not catch smallpox. The cowpox seemed to make them immune. By taking some bacteria from the arm of a person who was ill with cowpox, and giving it to a healthy person, Jenner found that he could transfer the immunity. Jenner’s process came to be known as vaccination, from the Latin word “vacca”, meaning “cow”. Because of vaccination, smallpox, one of man’s greatest enemies, has been practically wiped out.

III. Translate the following paragraphs into Vietnamese

Paragraphs 1

Viral hepatitis (commonly called jaundice because of the yellowish tinge to the skin) is due to a viral infection in the liver. Hepatitis can be contracted from contaminated food, hypodermic needle, or blood transfusion. Symptoms of the disease do not usually appear until after incubation period of several weeks. These symptoms include the loss of appetite, fatigue, fever, and nausea in addition to the yellowish color. Hepatitis can be treated with gamma globulin.

Paragraphs 2

An important function of the nervous system is to pick up sensations of light, sound, touch, taste, heat, cold, pain… etc……. These sensations are carried from sense organs to the brain over the sensory nerves. The brain receives these messages of sensations and reacts to them, makes plans, and sends orders to for action. These orders are carried by the motor nerves to the muscles of a particular part of the body

Paragraphs 3

High blood pressure (HBP) is a serious condition that can lead to coronary heart disease (also called coronary artery disease), heart failurestrokekidney failure, and other health problems.

“Blood pressure” is the force of blood pushing against the walls of the arteries as the heart pumps blood. If this pressure rises and stays high over time, it can damage the body in many ways.

Paragraphs 4

Nausea and vomiting are associated with stomach and intestinal disorders such as flu, food poisoning, or dysentery. Chest pain or a congested feeling can be a symptom of heart trouble while sweating, itching, and rashes are skin manifestations of problems such as allergies, or even cancer.

Paragraphs 5

People notice changes in their bodies which they associate with illness. These are called symptoms. The most clearly recognizable symptom is pain. A pain in the stomach may indicate simple indigestion or a more serious ailment such as an ulcer or dysentery. A headache is associated with colds, the flu, and head injuries while a pain in the chest may be a warning of a heart attack or lung trouble.

Paragraphs 6

You have more calcium in your body than any other mineral. Calcium has many important jobs. The body stores more than 99 percent of its calcium in the bones and teeth to help make and keep them strong. The rest is throughout the body in blood, muscle and the fluid between cells. Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.

Paragraphs 7

Osteogenesis imperfecta (OI) is a genetic disorder in which bones break easily. Sometimes the bones break for no known reason. OI can also cause weak muscles, brittle teeth, a curved spine and hearing loss. The cause is a gene defect that affects how you make collagen, a protein that helps make bones strong. Usually you inherit the faulty gene from a parent. Sometimes, it is due to a mutation, a random gene change.

Paragraphs 8

Although bacteria are known to cause harmful diseases in humans and other organisms, it is a seldom recognized fact that bacteria actually help us fight the very disease they cause. It is through vaccines and antibiotics that medical science has made use of both the pathogenic bacteria and their toxins.

Paragraphs 9

It is important to get plenty of calcium in the foods you eat. Foods rich in calcium include diary products such as milk, cheese and yogurt, and leafy, green vegetables. The exact amount of calcium you need depends on your age and other factors. Growing children and teenagers need more calcium than young adults. Older women need plenty of calcium to prevent osteoporosis. People who do not eat enough high-calcium foods should take a calcium supplement.

Paragraphs 10

Hypertesion has been called “the silent killer” because it gives no warning. In the early stages of this disease, there often are no symptoms. As the disease develops, people may have complaints which they do not investigate. They may complain of headaches, vision changes, or problems with their urinary ouputs. If they consulted a physician, permanent damage to a viral organ would be avoided. Some people with HBP do not seek help until they have a stroke. By this time there is often permanent damage to one’s vital organs

Paragraphs 11

Your bones grow thicker as you get older. The thin covering the outside of the bones put down hard new bone cells to make the bone thicker and stronger. During your growing years, the end of your long bones is fastened to the bone shaft, mainly by a wide cartilage plate known as the growth plate, or epiphysis. Gradually bone cells come up from the shaft and start destroying the cartilage cells and putting down hard new cells in their place

Paragraphs 12

The largest, most significant role in which bacteria are involves is the decomposition of waste materials on earth and in process, the maintaining of a balance in nature. Without these saprophytic bacteria, the remains of dead organisma and plants would not decay and the waste would accumulate so fast that it would soon interfere with the life of new generations

Paragraphs 13

Despite the common and valid association of bacteria to deadly germs and disease, bacteria also have other very important roles in nature. Not only do these tiny organisms help fight disease in humans, but they also maintain the fragile balance on earth and are often used in the chemical and mining industries. These are just a new of the positive influences that certain bacteria have on the lives of living organisms

Paragraphs 14

A lot of water is necessary for the chemical reduction of food into its end products. Food is moved along the length of the intestines by the rhythmic contraction of the muscle walls. This is called peristalsis. What is left of the food, after some has been absorbed by the small intestines, moves through the large intestines where water is reabsorbed into the body. The material that cannot be used by the body is excreted from the rectum through the anus as feces or waste

Paragraphs 15

Most colds are caused by viruses rather than getting wet or standing in a draft, as is the common belief. The symptoms of a cold may include a runny nose, a cough, a sore throat, a fever, and various aches. None of the antibiotic drugs, such as penicillin, are effective in treating a cold. Drinking tea with honey and whiskey, a common home remedy, does not cure a cold nor does taking massive doses of Vitamin C. About all one can do is stay in bed and rest for five to seven days duration of the illness. Happily, most virus infections in otherwise healthy people are self-limited

Paragraphs 16

Vaccines are used to produce an acquired immunity. A person is vaccinated with a living but weakened germ, a killed germ, or a toxic poison from the germ. The body responds by developing an immunity to the germ. Because this acquired immunity often does not last a lifetime, it may be necessary to immunize people periodically with booster shots of the vaccine

Paragraphs 17

Bone is a hard substance that forms the framework around which the body is built. This framework, or skeleton, contains over 200 separate bones that support and give shape to the body and protect its vital organs. Contrary to a common misconception, bone is a living substance! In fact, bone is one of the most active tissues in the body. It is constantly being broken down and being rebuilt in a process remodeling and, like any other living tissue, needs nourishment to stay strong and healthy

Paragraphs 18

The liver is the place where toxins or poisonous substances are removed from the blood. Damage to the liver can be caused by drinking alcoholic substances or taking drugs that are harmful to its tissue. The liver is also responsible for the production and storage of some elements necessary for proper circulation of the blood and for blood clotting. Blood clots are not always bad. When a blood vessel has been injured, a clot may form that holds the blood within the closed vessel until healing occurs

Paragraphs 19

Muscular tissue is composed of long, thin cells, or fibers, which can contract and relax. Groups of muscles work together to perform a body motion. These muscles can be classified as smooth or striated, depending on what they look like under a microscope. Two groups of muscles that work together are called antagonistic grows. Extend your forearm. The biceps muscle relaxes while the triceps contracts. Abduction means moving a part away from the body, and adduction means moving it toward the body

Paragraphs 20

Proper breathing involves drawing in through the nose. The nasal cavity warms and moistens the air and filters it of impurities. Tint hair and sticky mucous membranes trap foreign materials before they can enter the delicate tissues of the lung. Structure in the nasal cavity called concha increase the surface area allowing maximum efficiency

Paragraphs 21

The sinuses are hollow areas, or cavities in the bones of the skull that are lined with mucous membranes and that open into the nasal cavity. The sinuses provide resonance for the voice. When the sinuses are inflamed and filled with mucus, the voice has a different quality, often referred to as nasal in character

Paragraphs 22

There are three main types of cancer. A carcinoma originates from the surface cells of the skin or the linings of the internal organs. A sarcoma attacks the muscles, bones, tendons, cartilage, fat, blood vessels, lymph system or connective tissue. Leukemia afflicts the blood forming cells. Some cancers grow slowly; others spread rapidly, doubling in bulk in days. Cancers can appear anywhere in the body but some common sites are the lungs, the breasts, the uterine cervix, the skin, the colon, and the blood

Paragraphs 23

Diabetes is a disease in which the body no longer uses sugar properly. In a healthy body special cells in the pancreas secret the hormones insulin and glucogin which help to store sugar. This no longer happens when one suffers from diabetes. A victim of diabetes thus must limit sugar and starch intake and possibly take daily injections of insulin

Paragraphs 24

Allergies are common, and may increase with environmental deterioration. Person who cannot tolerate certain foreign substances may react with a rash or hives, with hay fever or asthma, or with eczema or other manifestations. The substance acts as an antigen which stimulates excessive antibody reaction. The reaction can usually be weakened by medication or by desensitization injects, but the only real cure is to avoid the allergies

Paragraphs 25

Different genes are activated in different cells, creating the specific proteins that give a particular cell type its character. A gene is the basic unit of heredity in a living organism. All living things depend on genes to hold the information to build and maintain their cells and to pass on their traits to offspring. In general terms, a gene is a segment of nucleic acid that, taken as a whole, specifies a trait. The colloquial usage of the term gene often refers to the scientific concept of an allele

Paragraphs 26

There are three ways that strong bones are dependent on proper nourishment. First, keep the bone cells healthy and active. Second, supply the variety of important nutritional building blocks needed to form the organic matrix of bone. Finally, supply the complex of minerals that need to be placed on that organic net making up

Paragraphs 27

Paget’s disease of bone causes your bones to grow larger and weaker than normal. They also might break easily. The disease can lead to other health problems, too, such as arthritis and hearing loss. You can have Paget’s disease in any bone, but it is most common in the spine, pelvis, skull and legs. The disease might affect one or several bones, but not your entire skeleton. More men than women have the disease. It is most common in older people

Paragraphs 28

Although it is not usually difficult to produce anesthesia in patients, the skills of a carefully trained anesthetist are necessary, for anesthetic drugs can be dangerous. The anesthetist must prepare the patient with a series of preparatory drugs. He or she must also keep careful watch of the patient’s vital signs throughout the operation to assure that they remain as close to normal as possible

Paragraphs 29

Oxygen os absorbed into the body during breathing. Carbon dioxide is released from the body during breathing. Water vapour is also lost during breathing. You should know about the internal structure of the lungs. The windpipe (trachea) branches into 2 bronchi (one to each lung). Cartilage rings in the walls of the windpipe help to keep it open however much you twist your neck. The bronchi split into smaller and smaller tubes called bronchioles. The bronchioles end in microscopic air sacs. These air sacs are lined with mucus and are surrounded by a network of blood capillaries

Paragraphs 30

The epiglottis is flap of cartilage in the throat behind the tongue and in front of the larynx. The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows, the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs. After swallowing, the epiglottis returns to its original upright position
