     The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals and an aesthetics. Patients do riot often believe they really need surgery- cutting into a part of the body as opposed to treatment with drugs.  

     In the early year of the 20th century, there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Clogged blood vessels can be clean out, and broken ones mended and replaced. A lung, the whole stomach, or cvcn part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation.  

     The scope of surgery has increase remarkable in the past decades. Its safety has increased, too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example, to certain types of birth defects in new born babies, and at the other end of the scale, to life-saving operation for the octogenarian. The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks.  

     One of the most revolutionary areas of modern surgery is that of organ transplants. Until a few decades ago, no person, except an identical twin, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful.

     "Spare parts" surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if the doctors say to you: "Yes, I think it is possible to operate on you for this condition". 

Today, compared with 1910, __________

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 30 to 34  

     In Africa, people celebrate with joy the birth of a new baby. The Pygmies would sing a birth-song to the child. In Kenya, the mother takes the baby strapped to her back into the thorn enclosure where the cattle are kept. There, her husband and the village elders wait to give the child his or her name.  

     In West Africa, after the baby is eight days old, the mother takes the baby for its first walk in the big, wide world, and friends and family are invited to meet the new baby. In various African nations, they hold initiation ceremonies for groups of children instead of birthdays. When children reach a certain designated age, they learn the laws, beliefs, customs, songs and dances of their tribes. Some African tribes consider that children from nine to twelve are ready to be initiated into the grown-up world. They may have to carry out several tests.  

     Maasai boys around thirteen years old to seventeen undergo a two-stage initiation. The first stage lasts about three months. The boys leave their parents' homes, paint their bodies white, and are taught how to become young warriors. At the end of this stage, they have their heads shaved and they are also circumcised. At the second stage, the young warriors grow their hair long and live in a camp called a “manyatta" where they practice hunting the wild animals that might attack the Maasai herds. This stage may last a few years. When they are ready, they will marry and become owners of large cattle herds like their fathers. The girls are initiated when they are fourteen or fifteen. They are taught by the older women about the duties of marriage and how to care for babies. Soon after that they are married and lead a life similar to that of their mothers.
