Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose ans amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person’s diet. This translates to about 75-100 grams of carbohydrates per day.
A diet that is deficient in carbohydrates can have an adverse effect on a person’s health. When the  body lacks a sufficient amount of carbohydrates, it must then use  its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketones in the body that causes fatigue, lethargy, and bad breath.

Which of the following do carbohydrates NOT do?

Choose the option (A, B, C or D) that best completes each of the following sentences.

My aunt is one of those people who can talk to anyone about anything. If she goes to a party where she doesn't know any of the people, she just walks up to the first person that she sees and introduces herself. And yet she doesn't seem to talk about deeply important things like politics or religion. She always starts off on something very obvious like the other person's job. Very soon she's talking as if she's known the other person for years. I asked her once what her secret was. She said that the most important thing in a conversation was listening. People love to talk about themselves, so if you allow them to do so, it's very easy to keep a conversation going. You have to listen very carefully and ask questions. And you have to look interested, too. So don't keep looking at other things in the room while you're talking to someone.

Another thing that I've noticed is that she only pays people compliments. She says: “I like your hair. Which hairdresser do you go to?” or “You look very well. Have you been on holiday?” Friendly messages like this seem to provide an easy way into a conversation.

What should you NOT do when you have a conversation with someone?

Advantages of Living in a Big City

Do you live in a big city? It is said that living in big cities is expensive because of the high living cost. There are also pollution and traffic problems that make living in big cities unpleasant. However, many people enjoy living in big cities because they offer convenience and countless options for entertainment.

Many big cities already have good public transportation systems, which make it easy for the citizens to go anywhere around the city. This also reduces and helps overcome the problem of traffic jams that often occur at peak times. With the convenience of public transportation, the citizens do not have to drive everywhere and can save money as they do not have to pay for parking charges.

Staying healthy is everybody’s concern and in big cities you can find the best possible medical care for any diseases, especially the severe ones. Moreover, compared to rural areas, access to medical treatment is easier because there are always clinics or medical centers that open 24 hours in many parts of the city so you can get medical help anytime, as soon as you need it. Reaching hospitals is also easier as public transport is usually available 24 hours a day.

There is a saying that big cities never sleep. This is true for some cities in which the nightlife begins just when people in other cities are ready to go to bed. Big cities like New York, Madrid, London and Paris have vibrant nightlife. People can still find entertainment, dine out or go shopping into the early hours. 

City dwellers are usually more diverse and there are many communities that hold social events or parties, which provide interesting opportunities for social interactions and social networking. The social interactions allow you to learn about other cultures and share interests with people from different backgrounds, which makes you more open minded and able to understand individuals. On the other hand, the social networking helps you to broaden not only personal but also professional relationships.

All in all, living in big cities is more convenient because of the complete facilities provided. The advanced transportation system enables the citizens to access public facilities easier, cheaper and faster. Big cities also provide better education and health service. In addition, city life is more fun and exciting because there is a wide range of entertainment to enjoy and a lot of social events to attend. 

Why do many people like living in big cities?

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 anaesthetics. 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. Cloyed blood vessels can be clean out, and broken ones mended and replaced. A lung, the whole stomach, or even 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 twins, 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, l think it is possible to operate on you for this condition”.

The main difficulty with organ transplants is     .
