1、英文小故事(文本)Driving on Ice (冰上跳舞)-英文故事-幼儿故事- When the ice is that thick it becomes possible to actually drive a car or truck across the ice. While driving on ice sounds like something that people would do just for fun, a lot of people drive across frozen lakes for very practical reasons.For example, th

In the middle of winter the only practical way of traveling to the mainland is by driving across the frozen lakes.Actually, when the lake is frozen two to three feet deep, this is a perfect opportunity for people living on is
3、lands to transport large objects onto or off the islands. Say, for instance, you owned a cabin on a small island in the middle of a lake in Michigan. Suppose you decided that you wanted to build an extra room onto the cabin.Transporting all the building materials onto the island using a boat would t

But almost every car and truck that drives on ice has snow tires, which creates extra friction between the tires and the ice. Some people also choose to put chains on t

If you walked up to such a road and did not know that the road was traveling over a lake, you might never suspect that the cars and trucks are actually driving across solid ice.
