  • 第12题：

    单选题
    An electrical appliance company has submitted a new model of washing machine for stress and durability testing. After the conventional round of tests, 26 of the 90 machines tested no longer functioned. Observing these results, the company determined that the washing machine model was acceptable for the consumer market.　 Which of the following, if true, most strongly supports the company’s decision regarding the washing machine?
    A

    When the number one rated washing machine was submitted for stress and durability testing, 96 out of 100 machines were still functioning at the end of the test.

    B

    Because of the extreme stress of the testing process, any model that has more than two-thirds of its machines functioning at the end of the test process is considered sufficiently durable for the consumer market.

    C

    Most consumers will tolerate a washing machine that functions only 64 times out of 90 attempts.

    D

    Although the model tested is less durable than other models on the market, its projected price is considerably lower than that of the most durable models.

    E

    The electrical failure that brought down most of the 26 washing machines that ceased functioning could probably be avoided if the machine were redesigned.


    正确答案： A
    解析：
    该公司的产品不合格率为26/90，小于1/3，故B项最能支持公司的决定，所以本题选B项。

    请阅读 Passage 1，完成第 21~25小题。Passage 1These days，many large city buildings are equipped with their own air-conditioning systems.These systems help keep the buildings cool，but they can also damage the environment.Since they use a lot of electricity，for instance，they contribute indirectly to global warming.In addition，the water that flows through the systems is often cooled using chemicals called chlorofluorocarbons，or CFCs，that are believed to damage the Earth's ozone layer.Recently，though，a system has been built in the city of Toronto，Canada，that cools buildings with little damage to the environment. In the traditional air-conditioning systems found in most large buildings，water is pumped through the building in a continuous cycle.The water is first cooled to a temperature of 4℃ in machines called chillers.It is then sent to individual units that cool the air in each room.As the water flows through the building，it gradually becomes warmer.Finally，it reaches the roof ，where it is left to cool down naturally in a water tower.After that it is returned to the chillers，where the cycle begins again.Toronto lies on the shore of Lake Ontario，one of North America's Great Lakes，and the new system makes use of cold water taken from about 80 meters below the surface of the lake.At this depth，the water in the lake remains at 4℃ all year round.This is exactly the temperature to which the water in air-conditioning systems is cooled.However，the water from the lake is not pumped directly into the air-conditioning systems.Instead，it is used to cool the water that is already inside the air-conditioning systems.After that，the lake water is added to the city's ordinary water supply.Enwave，the company that developed this deep-lake cooling system，says that it uses 75 percent less energy than traditional air conditioning.And since no CFCs are used，no damage can be caused to the ozone layer.Not every city is located next to a large lake，but experts believe that systems like the one being used in Toronto could be built elsewhere by using other natural sources of cold water.What is one advantage of Enwave 's new system?
    A

    It keeps buildings much cooler than other methods.

    B

    It can be used by large cities anywhere in the world.

    C

    It is much more energy-efficient than traditional systems.

    D

    It keeps water from being used for more than one purpose.
