当我们要表示“想做某事、需要做某事或决定做某事”时，就会出现两个动词连用的情况，同学们自然会想到用wanttodosth,needtodosth和decidetodosth等表达方式。行为动词后的动词都采用了“to+动词原形”的结构。我们把这种结构称为动词不定式。动词不定式没有人称和数的变化，在句中不能作谓语。那么动词不定式有什么样的语法功能呢?首先，它可以在句中充当宾语成分。Presentation课本129页Weonlyplannedtowatchforanhour.动词不定式和动名词作宾语Presentation课本129页Eg：IwantedtoseetheBeiiingopera,soLiLingofferedtotakemethere.Weonlyplannedtowatchforanhour.需要注意的是：在英语中，并不是所有的动词都可以用不定式作宾语。有一些动词只能用动名词作宾语。Eg：Sheenjoyslearningaboutdifferentculturesandtraditionsfromaroundtheworld.Presentation动词不定式的基本形式为：to+动词原形；动名词的基本形式为：v.+-ing。注意：1.动词不定式是一种非谓语形式，在句中不能作谓语，其形式不随主语的人称、数和时态的变化而变化。2.动名词是由“动词原形+-ing”构成，相当于名词的功能。动词不定式和动名词作宾语一般来说，用不定式作宾语时，所表示的多为将来的行为。但是，在具体使用中同学们还要注意记忆，因为动词不同，对其后动词形式的要求也不同。Doyouwanttosayanything?你想要说什么吗？·Heofferedtolendmesomebooks.Presentation考点1：
