Unit 3 语法讲解及习题：动词不定式（The Infinitive）2026-2027学年外研版英语九年级下册
外研英语九下Unit3语法讲解及习题：
动词不定式（The Infinitive）
动词不定式基本结构：to + 动词原形，否定形式：not to + 动词原形；部分场景可以省略 to，叫作不带 to 的不定式。不定式属于非谓语动词，不能单独作句子谓语，主要用来作主语、宾语、宾语补足语、定语、状语，也是本教材三个原句对应的核心考点。
例句语法拆解
(a) Did Leonardo da Vinci want the Mona Lisa to live behind a wall of glass?
解析：want sb to do sth，不定式充当宾语补足语，想要某物做某事。
(b) ... it needs to be where people can reach it!
解析：need to do sth，不定式作动词 need 的宾语。
(c) Artists paint on walls to make cities and towns more beautiful.
解析：不定式置于句末，充当目的状语，用来解释作画的目的。
常接不定式作宾语的高频动词：want, hope, plan, decide, refuse, learn, choose, try, agree, wish, prepare 等。
例句：Many artists choose to create works that warm people’s hearts.
许多艺术家选择创作抚慰人心的作品。
2. 作宾语补足语（动词 + 宾语 + to do，补充说明宾语动作）
1）必须带 to 的结构：want/ask/tell/allow/encourage/persuade/order sb to do sth
例：Teachers encourage students to design their own artwork. 老师鼓励学生设计专属艺术作品。
2）主动语态省略 to 的不定式（使役动词、感官动词）

make/let/have sb do；see/hear/watch/notice/feel sb do
变为被动语态时，必须还原 to，是中考高频易错点
例：The painter made the colours stand out.
The colours were made to stand out by the painter.
用来表示动作发生的目的，翻译为 “为了……”，可放句首或者句尾；放句首常用逗号隔开。
例句：People create tie-dye art to bring beauty to daily life.
人们制作扎染艺术，为日常生活增添美感。
To understand the painting, you need to know its background story.
为读懂这幅画作，你需要了解它背后的故事。
固定搭配：something to draw, a chance to show art talent
例句：She gets a good chance to show her sculpture. 她得到展示雕塑作品的机会。
句型：It is + adj. + (for/of sb) to do sth
• for sb：形容词用来描述这件事（important, necessary, easy, hard）
• of sb：形容词用来评价人的品性（kind, wise, careless, honest）
例：It is meaningful for teenagers to learn different forms of art.
学习各类艺术对于青少年很有意义。
It is creative of her to make artwork from waste materials.
她利用废料创作艺术品，很有创意。
例句：My dream is to become an outstanding artist. 我的理想是成为一名优秀艺术家。
7. 疑问词 + to do（what/where/when/how/who + to do），可充当宾语
例：She doesn’t know how to draw Mondrian’s classic paintings.
她不知道如何绘制蒙德里安的经典画作。
