I tried to wake up my wife by ringing the door-bell, but she was fast asleep, so I got a ladder from the shed in the garden, put it against the wall, and began climbing towards the bedroom window. I was almost there when a sarcastic voice below said, “I don’t think the windows need cleaning at this time of the night.” I looked down and nearly fell off the ladder when I saw a policeman. I immediately regretted acting in th e way I did, but I said, “I enjoy cleaning windows at night.”“So do I,” answered the policeman in the same tone. “Excuse my interrupting you. I hate to interrupt a man when he’s busy working, but would you mind coming with me to the station?”“Well, I’d prefer to stay here,” I said. “You see, I’ve forgotten my key.”“Your what?” he called.“My key,” I shouted.Fortunately, the shouting woke up my wife who opened the window just as the policeman had started to climb towards me.41.

He was the only boy among great many girl cousins. That was enough to make him important, but his father loved him especially, because he knew his son was going to be an artist. Pablo knew the word for pencil even before he could say Mamma and Papa. When he was small he spent hours by himself making delightful little drawings of animals and people. If his mother sent him out to play in the square, he went on drawing in the dust under the trees. One of his favorite models was his younger sister, Lola.Don Jose Ruiz, Pablo’s father, was director of the museum at Malaga in southern Spain. He earned only a small salary, but there was not much work to do and he was able to practice his hobby, which was painting pigeons. Don Jose loved pigeons very much. He painted them dead or alive in ones and twos and in dozens. Sometimes he painted them on paper, cut them out and stuck them on to canvas; sometimes he stuck real feathers on to his pictures. He knew a great deal about the technique of painting and he taught it all to Pablo.46. Picasso’s father loved him particularly, because ______.A he was their only childB he was a boyC he was going to be importantD he was going to be a painter47.

Pablo’s father painted a lot because ______.A he had plenty of timeB he did not have much moneyC he looked after the museumD he liked pigeons50. Drawing pigeons was Don Jose’s ______.A workB leisure-time activityC regular businessD way to earn a livingPassage ThreeYou have been badly injured in a car accident. It is necessary to give you a blood transfusion.However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.There are four basic types of blood: A, B, AB, and O. A simple test can show a person’s blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is inherited from parents.Because of substances contained in each type, the four groups must be transfused carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can be given to any other group, and, hence, it is often called the universal giver. For the opposite reason, AB is sometimes called the universal receiver. However, because so many reactions can happen in transfusions, patients usually receive salt or plasma until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to avoid any bad reactions to the transfusion.There is a relationship between your blood type and your nationality. Among Europeans and people of European ancestry, about 42 percent have type A while 45 percent have type O. The rarest is type AB. Other races have different percentages. For example, some American Indian groups have nearly 100 percent type O.51. A good title for this selection is ______.A Getting Blood and PlasmaB Special Blood ColorsC Universal Giver and ReceiverD Human Blood Types52. The author suggests that the rarest blood type be _____ among Europeans.A AB BC ABD O53. People with type A blood can receive _______.A ABB BC OD all the above54. If you need a transfusion, the best and safest blood for you is _____.A type AB type ABC exactly the same type as yoursD a mixture of salt, plasma, and type O55. According to the passage, a person’s blood type is decided by _______.A his parentsB his nationalityC his hair colorD his heightPassage FourWomen’s fashions tend to change more rapidly than men’s. In the early 1900s all women wore their skirts down to the ankle. Today, skirt length varies from floor-length to ten inches above the knee. Women’s shores have also gone through all sorts of changes in the last seventy years. For example, boots for women were very common at the beginning of this century. Then, several yearslater, they were not considered fashionable. Today they are back in style again in all colors, lengths and materials. In fact, today’s women can wear all types of clothes—even T-shirts and shorts on almost any occasion. While there are some rapid changes in women’s clothing which remained pretty much the same until a couple of years ago, most men still wear the traditional suit, jacket, shirt and tie although there have been more changes about their clothing in color, pattern and variety than in the past.56.
