不定式在英语语法中具有重要的连词作用,可以连接两个主语、两个谓语或两个从句,使它们在同一句子中并列存在。掌握不定式的用法,可以使语言表达更准确且丰富。
连接两个主语
不定式可以用来连接两个主语,让它们在同一个句子中并列存在。例如:
- My dream is to travel around the world.
- His hobby is to play basketball in his free time.
在上述例句中,“to travel around the world”和“to play basketball in his free time”都是不定式,它们连接了主语“My dream”和“His hobby”,使得两个主语在同一个句子中并列存在。
连接两个谓语
除了连接两个主语,不定式也可以用来连接两个谓语,让它们在同一个句子中并列存在。例如:
- I like to read books and to watch movies.
- She wants to eat pizza and to drink soda.
在上述例句中,“to read books”和“to watch movies”以及“to eat pizza”和“to drink soda”都是不定式,它们连接了两个谓语“like”和“wants”,使得两个谓语在同一个句子中并列存在。
连接两个从句
不定式还可以用来连接两个从句,让它们在同一个句子中并列存在。例如:
- He told me to study hard if I want to get good grades.
- She asked him to come to the party if he is available.
在上述例句中,“to study hard”和“if I want to get good grades”以及“to come to the party”和“if he is available”都是不定式,它们连接了两个从句“He told me”和“She asked him”,使得两个从句在同一个句子中并列存在。
