Article: Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too. There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.

Options: (A) a lot of problems (B) words and easy grammar (C) words but no grammar (D) grammar but not many words

Article: On a warm Monday, Jenny Neilson bought a sandwich and parked her car under some trees. Rolling down the windows to let in fresh air, she settled back to enjoy her lunch. Suddenly she noticed a big _ man running through the parking lot. Before she came to realize what would happen, the man was there, shouting through her window, "Get out!" Neilson refused. Pulling open her door, the man seized her by the neck and hair, and threw her out of the car onto the ground. She screamed, grabbing her purse and the keys. Two reporters of the local newspaper, Robert Bruce and Jeff Jackson, just outside their office building on a break, heard the screams and began running . When they reached Neilson's car, the attacker had jumped into the driver's seat and was madly searching for the keys. Bruce opened the door, and he and Jackson dragged the man out. The attacker fought back. But even in his cornered panic, he was no match for the two athletic men. Reggie Miller, a worker of the local newspaper, heard the screams, too. He rushed back to the office to phone the police, and then ran back with some plastic ropes ---- used to tie up newspapers. With his arms tied tight behind him, the prisoner looked up and said coldly, "I hope you guys feel good about yourselves---- you just caught one of the most wanted men." They ignored him and waited for the police. Later, Bruce and Jackson were shocked to learn the man was the professional carjacker and suspected murderer, whose picture---- but with a full head of hair---- had been recently printed in their own newspaper. Neilson considers herself lucky though she suffered injuries. She believes the story might have had a different ending if those good people had not come to her aid. "Unfortunately," she said, "many people would never have done what they did, and that is the real truth."

Article: The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer just under the surface.The outside dead layers wear off all the time,with new ones replacing them,and the body forms a totally new skin every three weeks. The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria can't get in through the skin unless it is damaged. If the weather is cold,the blood vessels in the skin squeeze down,or contract ,so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even "blue".At the same time,the hairs on the skin are pulled upright by tiny muscles. When it is hot,the blood vessels expand ,or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands produce more sweat,which cools the skin. If your skin has ever been numb ,you will realize how important the feeling from the skin is.Nerves in the skin are sensitive to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways. The colour of the skin depends on special colour cells .These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may "tan" in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.
