Question

【题目】根据短文理解，选择正确答案。
On Monday, the Centers for Disease Control and Prevention predicted that 42% of Americans could be overweight by 2030. Our expanding waistlines lead to not only a medical problem, but according to a recent article In The New York Times, it could also endanger personal safety in some situations—in an airplane crash, for example.
The New York Times' Christen Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. Government standards for airplane seat strength（强度）— first set moe than 60 years ago — require that the seats be made for a passenger weighing 170 pounds (77kg). Today, the average American man weighs nearly 194 pounds (88kg) and the average woman 165 pounds (75kg). Negroni reports:
“If a heavier person completely fills seat, the seat is not likely to behave as intended during a crash,” said Robert Salazar, the leading scientist at the Center for Applied Biomechanics at the University of Virginia. “The energy absorption that is built into the aircraft seat is likely to be overpowered and the passengers will not be protected properly.”
“Nor would the injury be limited to that passenger only,” Dr. Salzar said. “If a seat or a seat belt fails,” he said, “those people who are seated nearby could be endangered from ‘the uncontrolled movements of the passenger'.”
Most complaints about airplane seats focus on their lack of comfort and high ticket price, and whether overweight passengers should be made to buy two seats. But The New York Times' article brings up another reason to feel anxious about flying. Investigators of the issue got in touch with the airplane seat and seat belt makers, but they refused to comment on the problem. Experts agreed that crash testing should be done with overweight dummies （人体模型）. Both airplane seats and seat belts should be tested, they said.
Fortunately, however, according to Nora Marshall, a senior adviser at the National Transportation Safety Board, the board's investigators have never seen an accident involving a commercial plane in which the weight of a passenger was a problem.
（1）What is the article in The New York Times mainly concerned with?
A.The size of airplane seats and seat belts.

C.Airplane crashes involving commercial planes.
D.A medical problem caused by being overweight.
（2）Robert Salzar would probably agree that .
A.overweight passengers should buy two seats
B.the government should help produce safer planes
C.standards for airplane seat strength should be raised
D.passengers should know how to protect themselves
（3）We can learn from the text that .
A.airplane seat makers have taken action now
B.there are few complaints about airplane seats
C.those seate near the overweight may suffer too
D.only a small number of airplane accidents involve the overweight
（4）What is the best title for the text?
A.Why Do Passengers Feel Anxious about Flying?
B.Will 42% of Americans Be OVERWEIGHT BY 2030?
C.When Will the Overweight Enjoy Their Flight?
D.Are Airplane Seats Safe Enough for the Overweight?

Answer 1

【答案】
（1）B
（2）C
（3）C
（4）D
【解析】本文是议论文。随着肥胖人群的增多，目前的飞机座椅能否保证他们的安全？本文围绕这一问题展开了论述。本文第一段引出话题；第二段首句为全文中心句，点明了文章的主旨，即目前的飞机座椅是否能够保证肥胖乘客的安全。

（1）细节理解题。根据第二段第一句“The New York Times' Christine Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. ”可知，这个报道主要关注的是肥胖乘客乘坐飞机的安全问题。故选B。

（2）推理判断题。“If a heavier person completely fills a seat, the seat is not likely to behave as intended during a crash,” said Robert Salzar,根据第三段大意可知，肥胖乘客乘坐飞机时，座椅不一定能够保证他们的安全，故可推断Robert Salzar很可能希望提高飞机座椅的强度标准。故选C。

（3）细节理解题。根据第四段中的““If a seat or a seat belt fails,” he said, “those people who are seated nearby could be endangered by 'the uncontrolled movements of the passenger'.””可知，肥胖乘客周围的乘客也可能会有危险。故选C。

（4）主旨大意题。随着肥胖人群的增多，目前的飞机座椅能否保证他们的安全？本文围绕这一问题展开了论述。本文第一段引出话题；第二段首句为全文中心句，点明了文章的主旨，即目前的飞机座椅是否能够保证肥胖乘客的安全，故D项为最佳标题。故选D。
