發(fā)布時(shí)間：2017-06-29 22:27:25New York, September 15. During a heavy rainfall last night a bus carrying 42 passengers slipped off the road on Highway 28, killing 36 of the passengers and the driver. A spokesman for the Highway Patrol(巡邏隊(duì)) who arrived at the scene shortly after 11:30 p.m. estimated(估計(jì)) that the accident had happened about half an hour before. The injured and the dead were sent to the nearest town of Valley View.At the point where the accident happened the road has a three-lane(三條行車線) highway with many curves(彎道). Cause of the accident has not been fully found out.1. It was very likely that the accident happened _______.A. after 11: 30 p.m. B. in the city of New YorkC. at or about 11: 00 p.m. D. in the town of Valley View2. How many people died in the accident?A. 37 B. 36 C. 43 D. 423. In consideration of what caused the accident, one should pay attention to _______.A. the careless driver B. the nearest town of Valley ViewC. Highway 28 D. the road with many curves1.C。推斷題。巡邏隊(duì)發(fā)言人晚上11點(diǎn)半到達(dá)，發(fā)言人說是大約半小時(shí)前發(fā)生車禍的，那車禍應(yīng)該是大約11點(diǎn)鐘發(fā)生的。2.A。細(xì)節(jié)題。36個(gè)乘客再加一名司機(jī)，當(dāng)然是死了37人。3.D。推斷題。因?yàn)樽詈笠欢蔚?句話At the point where the accident happened the road has a three-lane(三條行車線) highway with many curves(彎道)，所以答案為D。
