单选题Exchange a glance with someone, and then look away. Do you realize that you have made a statement? Hold the glance for a second longer, and you have made a different statement. Hold it for 3 seconds, and the meaning has changed again. For every social situation, there is a permissible time that you can hold a person's gaze without being intimate, rude, or aggressive. If you are on an elevator, what gaze-time are you permitted? To answer this question, consider what you typically do. You very likely give other passengers a quick glance to size them up (打量) and to assure them that you mean no threat. Since being close to another person signals the possibility of interaction, you need to emit a signal telling others you want to be left alone. So you cut off eye contact, which sociologist Erving Goffman(1963) calls "a dimming of the lights". You look down at the floor, at the indicator lights, anywhere but into another passenger's eyes. Should you break the rule against staring at a stranger on an elevator, you will make the other person exceedingly uncomfortable, and you are likely to feel a bit strange yourself. If you hold eye contact for more than 3 seconds, what are you telling another person? Much depends on the person and the situation. For instance a man and a woman communicate interest in this manner. They typically gaze at each other for about 3 seconds at a time, and then drop their eyes down for 3 seconds, before letting their eyes meet again. But if one man gives another man a 3-second-plus stare, he signals "I know you," "I am interested in you," or "You look peculiar and I am curious about you." This type of stare often produces hostile feelings. The passage mainly discusses ______.

单选题Venice is such a strange city. It is built on an Italian lagoon in the Adriatic Sea. It has canals instead of roads, which means there are no cars or buses, no trams or trains or bicycles running past us. Best of all, you could walk or jump or play hide-and-seek on its cobbled streets or its countless bridges whenever you choose to. Daily life in Venice skims over its waterways, especially the sweeping double curve of the Grand Canal and the 180 smaller water passages that run through the 118 islands that make up the city. For generations, tiny boatyards have built these lopsided boats, with one side curving further outwards than the other. Why? To balance the weight of the oarsman at the end of the boat. This Italian city is known for its festivals, especially the popular ten-day Carnival in April. Children, teenagers and adults dress in special costumes, unusual stockings and shoes, then do masks before they take part in this celebration. It's difficult to make out who is behind each mask, but it's easy to make friends during this constant party in the streets. What fun! On other occasions, Venetians celebrate with a regatta or boat race. The city loves the Vogalonga, on the first Sunday of May, best of all. That's when anyone who can row with oars is welcome to join the other boats on the great Grand Canal, especially in fancy dress. Imagine the sight! Venice is an unusual city, but it is facing an unusual threat. It's sinking. Since it's built on a lagoon, the weight of the city on the silt beneath it threatens its life. "Venice today is sinking three times as fast as before, at 300mm per century," explains an environmentalist. We feel sad about the thought that beautiful Venice, with its splendid churches, its collections of art and its happy spirit, may be buried under the sea someday. May the lion of St. Mark, the symbol of Venice, never face that day.

单选题In the U. S. today, the cost of housing is very high. It is common to pay one fourth to one third of a family's income on a place to live. The price of a house depends on its size and location. Big houses are more expensive than smaller ones, and houses closer to the center of big cities are more expensive than the ones in the suburbs or in small towns. Regardless of(不顾) the cost, it is usual for people to buy their houses over a period of time. When a family buys a house, it is necessary to borrow money from a bank to pay for it. Then they repay the bank in regular payments. This kind of bank loan is called a mortgage. Families usually take 30 years pay off the mortgage. Without a mortgage it would be impossible for most people to own their houses. Many Americans don't own their houses. They pay landlords to live in their homes. The money for this is called rent. Usually it is cheaper to rent than it is to buy and to pay a mortgage. Also, when something needs to be repaired, it is easy for the renter to ask the landlord to fix it. Some people rent houses, but most renters live in apartments. Apartment buildings are located in cities where it is too costly to build houses. Recently it has become common for renters to buy their apartments. When this happens, the cost usually increases but the money goes to pay off the mortgage. Apartments bought this way are called condominiums. What does the word "mortgage" (in Para. 2) mean in Chinese?
