Section Ⅲ　Learning About Language 　 UNIT 3 SEA EXPLORATION 课 时 精 练 语 法 探 究 边 角 拾 遗 内 容 索 引 语　法　探　究 索引 新知导学 教材示例 分析下列加黑部分并体会其语法功能 1．(教材原句)To complete the great map of the world was a strong passion for the people of early civilisations. 2．(教材原句)Marco Polo's tales inspired European explorers to search for sea routes from west to east. 复习动词不定式 3．(教材原句)Here，merchants from China and many other places met to negotiate trade deals，which also led to more awareness of each other's cultures. 4．(教材原句)These fleets were a sight to behold and were in a league of their own at that time. 5．(教材原句)To reach out across the sea remains a strong desire today. 6．(教材原句)The aim of this initiative is to encourage cooperation and trade across the historic Silk Road areas，and strengthen the bonds between China and the rest of the world. 7．(教材原句)Trading has grown greatly in recent years，and will continue to do so in years to come. 8．(教材原句)China has invested billions in systems and services along these routes，which will help to greatly develop the whole area for the benefit of future trade and cultural exchange. 9．(教材原句)Hundreds of years on，and with the latest technology in hand，the need to trade and the desire to enhance relationships will drive China to reach out across the sea far into the future. 我的发现 1．以上句子中黑体部分皆用了动词不定式。动词不定式在句中可充当主语(如句___和句___)、宾语(如句___和句___)、宾语补足语(如句___)、表语(如句___)、定语(如句___和句___)及目的状语(如句___)。 2．动词不定式一般式的结构为：_______。 1 5 7 8 2 6 4 9 3 to do 语法精讲 　　动词不定式的基本构成是“to＋动词原形”。to是动词不定式符号，无词义。动词不定式具有名词、形容词、副词和动词的特征。它可以在句中充当除谓语以外的各种句子成分。 Ⅰ.动词不定式的句法功能 动词不定式在句中可以作主语、表语、宾语、宾语补足语、定语和状语，它多表示具体的或某次具体行为。 一、作主语 动词不定式短语作主语时，谓语动词用单数形式。动词不定式短语作主语时，为了保持句子平衡，往往把主语放在句子末尾，而在它原来的位置上加上引导词it作形式上的主语。 To make you understand him completely is impossible. →It is impossible to make you understand him completely. 让你们完全了解他是不可能的。 To remember to switch off the electricity is important. →It's important to remember to switch off the electricity. 重要的是要记住关掉电源。 二、作表语 　在用动词不定式作表语的句子中，系动词除be外，还有seem，appear等。 Her wi
