问题     In June 2006, in Minato, Tokyo, a 16-year old high school student was killed by a Schindler elevator. He was backing out of it with his bicycle when the elevator suddenly rose with the doors still open, crushing his skull. Investigations began related to this fatality.
    In the process of this investigation, the safety of elevators in Japan came under question. 【R1】______The Japan Elevator Association disclosed that 9200 entrapments happened in Japan in 2004 in elevators of the big four Japanese elevator manufacturers(Mitsubishi Electric, Hitachi, Toshiba, and Fujitec).
    Results from a recent investigation in Hiroshima showed that 34% of Schindler elevators in the city have had problems. 【R2】______. As of June 14, 2006, the precise cause of the accident had still not been confirmed. 【R3】______The International Herald Tribune reported on June 14 that " Loose bolts and worn brake pads, evidence of poor maintenance, likely played a central role in the elevator accident.
    【R4】______The Asia Times Online reports that in response to a flood of inquiries from customers, the third-largest domestic elevator company, Toshiba Elevator and Building Systems Corp. is offering free inspections of their elevators, while Mitsubishi Electric Corp. , the leading firm, and Hitachi Ltd, which is the second-largest, are responding to requests on a case-by-case basis.
    In Hong Kong, many news agencies are finding similarities between the Minato case and the 2002 Fanling Hong Kong case. Thus, Hong Kong’s Public Housing Authority has been questioned about the 23 public estates with Schindler elevators. In comparison, Hong Kong law requires a full annual examination every year, load testing every 5 years, and an inspection every month. Some buildings have inspections every 2 weeks.
    A. There is a reported competition among elevator operators in Hong Kong, with some buildings opting to contract elevator maintenance to firms that offer low rates.
    B. The Housing Authority has said that all of its elevators are maintained by the original manufacturer(in Hong Kong’s case, by "Schindler Lifts Hong Kong Limited")and all elevators are inspected fully once every week.
    C. It should be noted that elevator maintenance had been carried out by a Japanese maintenance company and not by Schindler since 2005.
    D. That elevators are not infallible came as a surprise to many people, especially when it was discovered that of the 8, 800 Schindler elevators installed in Japan, 85 have trapped people.
    E. Japan has already ordered full inspections of the country’s entire set of Schindler elevators, with elevators of all manufacturers being inspected in government buildings.
    F. Public concern over the Minato case has not been limited merely to Schindler elevators.

选项

答案D

解析 D项说在日本8 800部Schindler电梯中85部都困过人。紧接着后文就表明在日本2004年四大电梯商就有发生9 200个被困住的事件。D句起承上启下的作用,D选项中的that elevators are not infallible是主语从句,指代的上一句话的内容。故选D。
