[单项选择]Luckily, the back tires of their car stayed on the road. Otherwise, the young couple would have driven right into a pit twenty feet wide and thirty feet deep!
The man and woman were coming home from a party. They were enjoying the landscape around Swansea, Wales. Suddenly, they found the front of their ear leaning into a huge hole. The car barely hung onto the edge of the pit. It swayed back and forth like the arm of a balance.
In their precarious position, the couple knew that each movement they made could be a matter of life and death. Slowly, slowly, they edged toward the backseat. Then each opened a back door. And on the count of three, they jumped out together. The accident was so scary that they ran a long way before they calmed down. But later they returned to see what had happened. They found that a big chunk of the road had sunk into the ground ! And at the bottom of the pit lay their car—roof down and wheels up.

[单项选择] When one of your car tires goes flat, there are two things you can do. Groan and change it or, if you don’’t have a spare, stand helplessly beside the road and hope someone comes to your rescue. Now comes a third alternative, called Quickwheel. It is designed to get disabled motorists rolling again as quickly as possible. Quickwheel is essentially a tiny emergency trailer—complete with three tough little wheels of its own—that supports the flat tire and enables the motorist to drive to a service station without losing much time or expending much energy. The product is manufactured in the Netherlands but is owned and marketed by a U. S. company, Quickwheel Inc. of Greenwich, Connecticut. According to the firm’’s president, Robert Bockweg, the product meets each of the major concerns that consumers associate with flat tires: safety, lost time and physical exertion. To use it, motorists simply unfold the product to its fully extended position, set it in front of the disabled
A. can’’t be used in place of a tire over long distance
B. will be available chiefly in the U. S.
C. can be folded and unfolded
D. functions well over various kinds of road surfaces
