问题     Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
    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(滑板) and give it a push. If the skateboard hits a stone, it will stop, but the egg won’t. It will fly through the air, hit the ground and break.
    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.
    Volvo, a famous Swedish carmaker, was the first to use seat belts in 1949. Air bags are also very important for car safety because sometimes a seat belt isn’t enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them.
    Most newer cars have air bags in front of and next to the seats. When a car hits something, its airbags will come out quickly in less than one second—to keep the people inside safe.
The best title for this passage is ______.
选项 A、Buy a Volvo with Airbags
B、Make a Car Safe Inside
C、Fasten Your Seat Belts
D、Add Air Bags to Cars
答案B
解析 主旨大意题。全文介绍了增强驾车安全的两项措施——安全带和安全气袋的使用。由此可见，选项B是正确答案。
