英文的不定詞是什麼意思
在英文中,不定詞(Infinitive)是動詞的一種形式,用來表示動作、行為或狀態。不定詞是由「to」加上動詞原形構成,例如 "to walk", "to study", "to eat"。不定詞可以用來做為句子中的主語、賓語、補語、狀語或插入語。
不定詞的用法包括:
- 做為主語:To study abroad is my dream.
- 做為賓語:I want to travel around the world.
- 做為補語:My plan is to move to another city.
- 做為狀語:She decided to stay at home.
- 做為插入語:To be honest, I don't like his attitude.
不定詞有時也會與動詞連用,形成「不定詞短語」,用來表達目的、結果、原因、假設等意義。例如:
- 目的:She went to the store to buy some milk.
- 結果:I tried my best to pass the exam.
- 原因:I'm sorry to hear that.
- 假設:If I had enough money, I would travel to Europe.
不定詞有時也會被動詞修飾,形成「被動式不定詞」或「進行式不定詞」,用來表達被動意義或進行中的動作。例如:
- 被動式不定詞:She is easy to get along with.
- 進行式不定詞:She is always trying to improve her English.
不定詞的否定形式是在「to」和動詞原形之間加上「not」,例如:
- 否定形式:I'm sorry not to hear from you.
不定詞的用法多樣,是英文學習者需要掌握的重要語法結構之一。
