Module 6 Animals in danger Unit 3 Language in use

Grammar 动词不定式

Revision 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，这时 应如何表达呢？ 同学们自然会想到want to do sth., need to do sth.和decide to do sth. 等表达方式。

什么是动词不定式？ 主要行为动词后面的动词都采用了 “to+动词原形”的结构，我们把这种 结构称为动词不定式（有时可以不带 to）。动词不定式没有人称和数的变 化，在句子中不能作谓语。下面我们 一起来看一下动词不定式有哪些语法 功能。

不定式作宾语 学习不定式作宾语时,要注意掌握:后接不 定式作宾语的动词。常见动词有: want, hope, wish, like, begin, try, need, forget, agree, help 等。 Many people decide to protect animals in danger. 许多人决定去保护濒危动物。 I want to go to the library. 我想去图书馆。

1. 我们需要帮助动物生活在安全的环境里。 We need ________ the animals live in peace. 2. 他决定去参观香港迪士尼乐园。 He decided ________ Disneyland Hong Kong. 3. 我忘记帮我姐姐买一支笔了。 I forgot __________ a pen for my sister. to help to visit to buy

我们可以发现动词不定式的另外两种语法功能： ①在“动词+宾语+动词不定式”的结构中充当宾语的补足语 ② 在句中表示行为动作的目的，作目的状语

动词不定式作宾语补足语 可用于“动词+宾语+动词不定式”这一结构的动词有很多，除本模块出现的allow，choose等词外，常见的还有：want, tell, ask, invite, help, need,等。 We want you to help us. 我们想要你来帮助我们。 Please tell Betty to come to school earlier. 请告诉Betty早点来学校。

需要注意的是： 1）以上动词接不定式作宾语补足语时，若要表达否定的意思，要在to do前加not, 构成not to do的形式。例如： My mom tells me to play football in the street. (改为否定句) My mom tells me ____ _____ ____ football in the street. Mr Han tells us not to sleep in class. 韩先生告诉我们上课不要睡觉。 She told me not to buy the concert ticket. 她告诉我不要去买音乐会的票了。 not to play

2）有些动词后接动词作宾语补足语时，可以接不带to的不定式，常见的这类动词有：make, let, have，help,等。例如： Let me make a cake for you. 让我做个蛋糕给你吧。 His words made everyone laugh. 他的话（ His words ）让大家哄堂大笑。
