Count On是什么意思?
短语动词是英语中独特且重要的组成部分,通常由动词与介词或副词(或两者)结合,产生与原始动词截然不同的新含义。短语动词“Count on”就是很好的例子。它的主要意思是依赖或信任某人或某事。你“Count on”一个人时,就是信任他们会支持你或者履行承诺。你“Count on”某事时,是指你期望它会发生或者可用。掌握“Count on”对于表达自信与信任至关重要,因此在英语口语与书面语中频率极高。正确使用它能让你的英语表达更加自然、流利。
Count On的句型结构
短语动词“Count on”十分灵活,是英语表达依赖关系的重要组成部分。作为不可分割的短语动词,“on”作为介词必须和所依赖的对象直接相连,这意味着“count”和“on”必须连用,后面跟被依赖的人或事。例如,你说“Count on someone”,而不是“count someone on”。
下面详细介绍其常见含义及句子结构:
含义一:依靠或依赖某人/某事(信任)
这是“Count on”最常见和核心的含义,表示对某人的能力/意愿或对某事的可靠性表示信任或信心。
结构一:主语 + count on + 某人/某物
- 这是最基础的结构,表示一般性依赖。
- Example 1: "You can always count on your family for support in difficult times."
- Example 2: "For our camping trip, we are counting on good weather to make it enjoyable."
结构二:主语 + count on + 某人/某物 + to + 动词原形
- 该结构明确表示依赖某人/某物去做某事。
- Example 1: "I count on my experienced colleague to guide me through the new project."
- Example 2: "She counts on her best friend to keep her secrets and offer honest advice."
结构三:主语 + count on + 某人/某物 + for + 名词/动名词
- 该结构明确指出依赖的理由或具体需提供的东西。
- Example 1: "The entire community counts on the local fire department for safety and emergency response."
- Example 2: "We count on Sarah for bringing the delicious homemade cookies to every party."
在此语境下使用“Count on”可以增强信心,也是表达相信某人或某事不会让自己失望的常见方式。
含义二:预期某事发生(期待)
这一用法表达了对某一事件或行为发生的期待或预期。表示你确信某种结果会出现;有时这种预期可能无法实现,从而导致失望。
结构一:主语 + count on + 某事(通常为动名词、名词短语或that引导的从句)
- 该结构强调预期的事件或结果。
- Example 1: "Given the heavy traffic, don't count on arriving at the airport in under an hour."
- Example 2: "He was counting on getting a significant raise this year, but the company announced a wage freeze."
结构二(带“it”):主语 + count on + it + that + 从句
- 这是更强调的表达方式,用于表达被认为是确定无疑的事。比简单结构稍正式或更强烈。
- Example 1: "It's a very popular concert; you can count on it that tickets will sell out quickly."
- Example 2: "We counted on it that the detailed instructions would prevent any confusion."
用“Count on”表示期待时,语气可以表达希望,也可以是对某种可能发生的不理想结果的警示。
含义三:确信某事,确定性(肯定)
这种用法与期待类似,但更强调确信或确定某一事实或将来事件。常用于陈述你认为是事实的观点,或当你希望别人给予你肯定时。
结构:主语 + count on + [名词短语 / that从句]
- 用于以高度自信的态度陈述某事。
- Example 1: "When visiting London, you can count on seeing many historical landmarks."
- Example 2: "Can I count on your discretion regarding this sensitive information?"
用于疑问句或否定句时: 常用来探询可靠性或对原有信心产生质疑。
- Example 1: "Can we really count on him to finish the project on his own?"
- Example 2: "I wouldn't count on the shops being open on a public holiday without checking first."
掌握上述结构和细微差别能让你更准确、有效地使用“Count on”于不同语境中。这一短语动词蕴含深厚的信任与预期色彩,是英语人际交流的核心之一。当你想让对方感受到你的信任时,说一句"I'm counting on you"会很有分量。
