"be willing to do"是英语中表达主观意愿的核心短语,以下是其详细含义与用法解析:
强调主语主动、自愿去执行某个动作,不含“被迫”或“勉强”的意味(区别于"have to do"“must do”等表“必须”的短语)。
该短语的基本结构为:be动词(随主语/时态变化) + willing(形容词,表“愿意的”) + 不定式(to do,表具体动作),具体用法如下:
be动词需根据主语人称和时态调整:
一般现在时:I → am;you/we/they → are;he/she/it → is
一般过去时:I/he/she/it → was;you/we/they → were
例:I am willing to help you.(我愿意帮你。)
She was willing to take the risk.(她之前愿意承担风险。)
They are willing to support our plan.(他们乐意支持我们的计划。)
在be动词后加not,表示“不愿意做某事”:
结构:be not willing to do 例:I'm not willing to wait any longer.(我不愿意再等了。)
He wasn't willing to admit his mistake.(他不愿意承认错误。)
将be动词提前至句首,用于询问对方意愿:
结构:Be + 主语 + willing to do? 例:Are you willing to join our team?(你愿意加入我们的团队吗?)
Was she willing to move to a new city?(她愿意搬到新城市吗?)
be more than willing to do:非常愿意;极其乐意(比原短语更强调主动性)
例:I'm more than willing to lend you my book.(我非常愿意把书借给你。)
be willing to do sth. for sb.:愿意为某人做某事
例:She is willing to sacrifice her time for her family.(她愿意为家人牺牲时间。)
1、 主语限制:通常是人(或拟人化的事物,如公司、组织),因为“愿意”是主观态度(无生命物体一般不使用)。
例:The company is willing to negotiate.(公司愿意协商。)(拟人化用法)
2、 不定式的作用:to do后接具体动作,明确“愿意做的事”,不可省略。
肯定句:We are willing to try new foods.(我们愿意尝试新食物。)
否定句:He isn't willing to compromise.(他不愿意妥协。)
疑问句:Are they willing to help us?(他们愿意帮我们吗?)
强调句:I'm more than willing to assist you.(我非常愿意协助你。)
简言之,"be willing to do"是描述“主动意愿”的高频短语,只要掌握be动词的变化和不定式的搭配,就能灵活运用啦!
