Module 6 Animals in danger 模块语法精讲 动词不定式(2) 动词不定式的结构：to+动词原形。有时可以不带to，没有人称和数的变化，属于一种非谓语形式，在句子中不能作谓语。 一、作主语：动词不定式主语常用it作形式主语，不定式是真正主语，常后置。句式：It is+adj. +to do sth. ①It is good to help others.帮助他人是件好事。 ②It is exciting to surf the Internet.上网是件令人兴奋的事。 二、作定语：不定式修饰名词或代词，起形容词的作用，在句中作定语，放在被修饰对象的后面。 There is no more room to live in.没有更多的房间居住。 三、作表语：动词不定式可以放在be或其他系动词后作表语，常表示具体动作或将来动作。 ①Our duty today is to clean the floor.今天我们的任务是打扫地板。 ②Our job is to feed the animals.我们的工作是喂养这些动物。 四、作补足语：补充说明表语或宾语。动词不定式在tell, ask, want等动词后作宾语补足语时，必须带不定式符号to. 但在使役动词（make, let, have等）和感官动词（watch, see, hear等）后作宾语补足语时，常省略不定式to. ①She told me to buy a ticket.她让我去买张票。 ②I’m sorry to hear that. 我很抱歉听到那件事。 五、作状语：不定式常常作目的状语、原因状语、结果状语等。不定式作状语时，要注意不定式的逻辑主语应与句子的主语保持一致。 ①I came to Beijing to see my grandpa. 我来北京看望我爷爷的。（作目的状语） ②I’m glad to meet you！很高兴见到你！（作原因状语） ③I’m too tired to walk. 我太累了，走不动了。（作结果状语） 模块语法精练 I.单项选择 1.— Where's your brother now, Bob? — 1 saw him ________ in the street a moment ago and I told him__________.
