Question

【题目】In many people's opinion, man's first real invention,【1】is also one of the most important inventions in history, 【2】 (be) the wheel. All transportation and every machine in the world depend【3】it. The wheel is the【4】(simple) yet perhaps the most remarkable of all【5】(invention) because there are no wheels in nature. How, then, did man come to invent the wheel? Perhaps some early hunters【6】 (find) that the body of a heavy animal could be rolled through the forest on logs (圆木) more【7】 (easy) than they could carry it. However, the logs 【8】 (them) weighed a lot. It must have taken 【9】 great prehistoric thinker to imagine two thin slices of log connected at their centers by a strong stick. This would roll along just as the logs did, yet be much lighter and easier【10】 (handle). Thus the wheel and axle(车轴) came into being and with them the first carts.

【解析】文章主要讲述了轮子是怎样产生的。

【1】考查定语从句。句意：在许多人看来，人的第一个真正的发明，也是历史上最重要的发明之一，是轮子。___1___is also one of the most important inventions in history是非限制性定语从句，修饰man’s first real invention，引导词在从句中做主语。故用关系代词which引导该从句。

【2】考查主谓一致。句意：人的第一个真正的发明是轮子。主语是单数名词，根据主谓一致原则，谓语动词用第三人称单数形式，填is。

【3】考查介词。句意：世界上所有的交通工具和机器都依赖它。depend on是固定短语，意为“依赖，依靠”。故填介词on。

【4】考查形容词最高级。句意：轮子是最简单的，但或许是所有发明中最引人注目的。该空和后面的the most remarkable对应，前面有定冠词the，故应使用最高级simplest。

【5】考查名词复数。句意：轮子是最简单的，也许是所有发明中最引人注目的。invention是可数名词，前面有all修饰，故填复数形式inventions。

【6】考查时态。句意：也许早期的一些猎人发现在穿过树林时，可以通过滚动原木运送沉重的动物。该空做谓语，根据earlier可知，该句介绍的过去的事情，故用一般过去时态。填found。

【7】考查副词。句意：也许早期的一些猎人发现在穿过树林时，可以通过滚动原木运送沉重的动物，这比他们自己搬运更容易。该空修饰动词carry，应用副词。故填easily。

【8】考查反身代词。句意：然而，原木本身重量很大。该空做the logs的同位语，故用反身代词。填themselves。

【9】考查冠词。It must have taken ___9___ great prehistoric thinker to imagine two thin slices of log connected at their centers by a strong stick这肯定需要一位伟大的史前思想家想发挥想象力，将两片薄薄的原木用一根结实的棍子连接在他们的中心。该空修饰thinker，指一位思想家，故填不定冠词a。

【10】考查动词不定式。这将像原木一样滚动，但更轻，更容易处理。该题考查be+adj.+to do结构。故填to handle。
