填空题 Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box. When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed. In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane–the area least subject to impact–from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility. Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 it. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

填空题The business memo(备忘录) is probably the most frequently used communication within a company. It is called an intra-company communication because it is used by people in their own company or organization. They change to letters, however, when they write messages to people who do not work for their company. A memo creates a written record that may or may not be filed, depending on the receiver and the subject. As you know, spoken messages may be misunderstood or forgotten. A memo, however, becomes a record that does much to ensure the complete communication between the sender and the receiver. The standard form of a memo frequently carries a pre-printed series of items: To, From, Date, and Subject. The first two items include the names of the receiver and the sender. A well-written subject line tells the reader the key topic or topics the memo is about. Business Memo Function: for communication within a 1 Purpose: 1) to keep a 2 2) to 3 the complete communication Items involved: 1) Receiver 2) 4 3) Date 4) 5

填空题Almost all of us thought his explanation was ______ (necessary) complex.

填空题There are two reasons why demand is related to price. For one thing, if your income stays the same, you can afford to buy more when the price is low. Secondly, records, for instance, are more attractive when their price is lower than the price of similar products. If records are less expensive than cassettes, you may choose to spend your money on records. In reality, the demand for a product is not always the same. It changes under different conditions. For example, taste may change. You may decide that you prefer cassettes because records are inconvenient. Consequently, you will buy fewer records at both high and low prices. Demand may also change as a result of changes in the prices of other products. For instance, the price of records stays the same, but the price of cassettes falls. Therefore, you buy more cassettes and fewer records. Or, income may change. Due to an increase in income, you can afford more records whether the price is high or low. The demand for a product has a close relation with 1 . One may choose 2 rather than cassettes because 3 . 4 may change under different circumstances, which affects demand. Regardless of price, 5 is a good way to increase demand.

单选题Telecommuting (远程办公) It" s 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his email and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John"s house, and he is a telecommuter—he works at home, communicating with the workplace through the Internet. Like John, millions of people--and their employers--are finding that telecommuting is a great way to work. Telecommuters can follow their own schedules. They work in the comfort of their homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems. Jobs that are suited to telecommuting include writing, design work, computer programming and accounting (会计). If a job involves working with information,a telecommuter can probably do it.
