　　Man’s first real inventions and one of the most important inventions in history was the wheel．All transportation and machines in the world depend on it．

　　The wheel is the simplest yet but perhaps the most remarkable(值得注意的)of all inventions．Because there are no wheels in nature－no living thing was ever created with wheels．How then did man come to invent the wheel? Perhaps some early hunters found that they could roll the carcass(尸体)of a heavy animal through the forest on log more easily than they could carry it．However the logs themselves weighed a lot．

　　It must have taken a great prehistoric(史前的)thinker to imagine two thin slices(薄片)of log connected at their centers by a strong stick this would roll along just as the logs did and axle(轴)came into being and with them the first carts．

Answer 1

答案：1．D;2．C;3．B;4．D;
解析：
(1) 第一段一开头就说，轮胎是历史上最重要的发明之一，接着说明的就是其重要之所在(All transportation and machines in the world depend on it)。 (2) 第二段提到轮胎可能是最值得关注的发明，因为没有什么天生就带有轮胎。 (3) 猎人只是用圆木来滚动那些笨重的动物尸首，而史前的思想者很难想到两片圆木的薄片用一根坚实的木棍连起来可以像圆木一样滚动，而这种想法使得第一辆马车诞生。可见，可能是第一个制造马车的人发明了轮胎。 (4) 从第3题可以得知第一个轮胎可能就是一块圆木薄片。
