单选题Passage Two It was sunrise on an August morning when the captain and his crew cast their nets some 50 miles south of Louisiana in the Gulf of Mexico. As the net was pulled over，the contents poured out followed by excited cries of "Coins！Coins!" The fishermen quickly realized they had realized a fisherman's dream：sunken treasure！And not just any treasure，but early American silver dollars that had gone down 210 years earlier. In 1784，at the end of the American Revolutionary War，a heavily armed ship was bound for the port of New Orleans. On board was a fortune in Spanish Silver Dollars. Hundreds of thousands of them were loaded for the trip to New Orleans，yet not a single one arrived. With no survivors from the ill-fated voyage，historians can only guess at what happened. Some say powerful storms took her down while others speculate it was treasure-hungry pirates(海盗). Whatever happened，the secret-along with a treasure valued near $100，000,000 in today' s dollars-was sent to a watery grave some 300 feet below the ocean's surface. Spanish Silver Dollars were the favorite coins of colonial Americans. Widely used and accepted as payment in the thirteen colonies，the United States government gave them the status of official legal tender. Unfortunately，even though they were struck in large quantities，not many of them survive today. After the Civil War，the government withdrew them from circulation and they were melted down. Due to the historic discovery of this treasure，Gov Mint . com is releasing these coins to the public for an amazingly low price. For a limited time，those authentic silver dollars are priced at $49 plus shipping and handling—a dramatic reduction from the market price of this coin anywhere else worldwide.  What surprised the fishermen on an August morning?

单选题Passage Three The environment affects the way people interact. To examine this conclusion，two researchers "decorated" three rooms：One room was refurnished to look ugly. The second room was intended to look average. The third room was designed to be beautiful. Individuals were then asked to sit in one of the three rooms and rate several pictures of people's faces. The results indicated that the environment has a significant effect on the way people rated the faces. Subjects in the beautiful room gave the pictures higher rates than did subjects in the ugly room. In addition，subjects in the ugly room found the task more unpleasant and boring than did subjects in the beautiful room. Subjects assigned to the ugly room attempted to leave sooner than did subjects assigned to the beautiful room. Color is one environmental factor that can affect your mood and even your ability to concentrate. One researcher concluded that the most pleasant colors，listed in order of preference，were blue，green，purple，red and yellow. The colors listed from most to least arousing were red，orange，yellow，violet，blue，and green. Lighting also affects behavior. Elegant restaurants with dim lighting create a mood of intimacy（密切）that encourages conversation. The bright lights of an office or classroom，on the other hand，arouse and stimulate thinking. Room decoration，color，lighting，and even music and temperature all influence communication with others；but there is no all-purpose environment. The ideal environment depends on the task that will be performed as well as on the needs and expectations of those present. The same environmental factors that encourage lively conversation and dancing at a New Year's Eve party cannot be expected to create a serene climate in which to study for final exams.  Paragraph 1 shows that subjects in the ugly room tend to be______.

单选题The scariest part of buying a used car is not being completely sure of what condition it’s in. A car that’s been in a major accident is always a bigger risk, but sellers often try to hide this information. Andrew Bleakley, evaluator-inspector, runs a mobile vehicle inspection service in Montreal. For about $ 80 he will perform a full, unbiased inspection on a used vehicle. In his 10 years as a professional inspector, Bleakley has seen a lot. He warns, “Watch out for dealer demonstration vehicles which are used, not new. They may have been in a collision.” He adds that it is not uncommon in Ontario and Quebec especially for unscrupulous sellers to roll back the odometer or to even disengage it. Bleakley has special tools to check for this. Bleakley always recommends hiring an independent technician to inspect the condition of a used car before you buy it. The problem is finding someone qualified to do the inspection, which he says generally doesn’t mean just any mechanic. A thorough mechanical inspection includes checking the compression, all major systems, including the engine, electrical and charging systems, transmission and drive line, fluids, brakes, suspension, and steering. Essential, too, is all inspection of the car’s body and finally a road test. There are, however, a few things everyone can do before buying a used car: Do a visual check of the car. Look at the right rear door hinges. If they are very worn, or the door doesn’t close well, the car may have been used as a taxi. Holes in the roof could mean the car was used for deliveries. Check for oil leaks on the pavement. Note that leaks are not necessarily a significant problem—it depends on the cause. Don’t assume that new-looking brake and accelerator pedals mean the car hasn’t been driven much. Resellers know people check these details and can buy new pads for around $ 6. Copy down the vehicle identification number(V1N), a 17-character combination of numbers and letters, from the vehicle’s dashboard. In Ontario, ask the dealer or seller for the Used Vehicle Information Package. This gives details of previous owners, any outstanding liens on the car, and the fair market value of the vehicle. According to the passage, in buying a second-hand vehicle it is most important to know
