解答 答案：66．A  主旨歸納題．根據整篇文章內容及其第四段句子Volvo，a famous Swedish carmaker，was the first to use seat belts in 1849．沃爾沃，一個著名的瑞典汽車制造商，在1849年第一個使用安全帶．和最后一段第一句Air bags are also very important for car safety，對于汽車安全氣囊也很重要．可知文章介紹了駕車和乘車時系安全帶自我保護的原理以及安全氣囊是如何保護駕車人和乘車人安全的．故選A．
67．C   細節理解題．根據第二段第一行句子It's always a good idea to put on your seat belt when you're in a car．Why？Think about this example：You put an egg on a skateboard and give it a push．If the skateboard hits a stone，it will stop，but the egg won't．當你在車里時，系好安全帶總是一個好主意，為什么？想想這個例子：你把一個雞蛋放在滑板上推一下，如果滑板撞到石頭，它就會停下來，但是蛋不會．和第三段句子Now，think what would happen if you tied the egg to the skateboard．When the skateboard hits a stone，the egg won't go flying； it will stay safely on the skateboard．現在想想如果你把雞蛋綁在滑板上會發生什么事，當滑板撞到石頭上時，雞蛋就不會飛了，它會安全地留在滑板上．可知通過將雞蛋系在滑冰板上再碰石頭，而雞蛋不破的原理來告知人們乘車駕車系安全帶的重要性．故選C．
68．C   細節推理題．根據第三段句子Now，think what would happen if you tied the egg to the skateboard．When the skateboard hits a stone，the egg won't go flying； it will stay safely on the skateboard．現在想想如果你把雞蛋綁在滑板上會發生什么事，當滑板撞到石頭上時，雞蛋就不會飛了，它會安全地留在滑板上．可知通過將雞蛋系在滑冰板上碰石頭而雞蛋不破的原理，告訴我們系安全帶可以讓人在座位上處于安全狀態．故選C．
69．B   細節理解題．根據最后一段第二行句子When a car hits something its air bags will come out quickly in less than one second to keep the people inside safe．當一輛汽車撞上某東西時，它的氣囊會在不到一秒鐘的時間內迅速打開，保護里面人的安全．可知當發生相撞時安全氣囊打開，同樣起到保護安全的作用．故選B．
70．D   細節判斷題．根據第四段句子Volvo a famous Swedish carmaker was the first to use seat belts in 1849．沃爾沃一個著名的瑞典汽車制造商，在1849年第一個使用安全帶．可知沃爾沃是第一個用安全帶的是正確的．故選D．
