美语听力与发音技巧第七期:冠词“a”

小白老师2015/12/07英语学习

摘要: 英语冠词“a”的使用取决于名词在句中的可数性:当名词表示可数意义时需加“a”,表示不可数或泛指部分时则省略冠词。

  • 冠词“a”用于可数名词单数前,表示一个完整、独立的个体。
  • 省略“a”通常意味着名词在此语境中为不可数,指代物质、类别或部分量。
  • 同一名词在不同语境下可能既可数又不可数,如“hair”和“cake”,需根据具体含义判断是否使用“a”。
  • 错误使用或省略“a”可能导致语义偏差甚至误解,例如“I like a dog”与“I like dogs”含义截然不同。

Welcome to Daily Tips on Learning English. Today’s tip is on using or omitting the English article “a” correctly.

There’s no single rule that explains how to choose whether you should use “a”, use “the” or not use any article at all. Sometimes there’s only one correct choice, and in other cases, different choices change the meaning of the sentence. Today let’s discuss the most frequently occurring differences between using the article “a” and using no article. All English nouns can be divided into 2 classes: those that are countable and those that are uncountable.

It is the meaning of a noun as it is used in a sentence which determines whether it is countable or uncountable. For instance, in the sentence “She has long hair.”, “hair” is uncountable. But in the sentence “There’s a hair in my soup.”,” hair” is countable. This can create some interesting mistakes. For example, “I like a dog” does not mean 我喜欢狗, that should be “I like dogs.” If you say “I like dog”, that means you like to eat dog meat. If you say “I ate a hamburger”, that means 我吃了一个汉堡, but if you say “I ate hamburger”, that means you ate raw ground beef. If you say “I ate a cake’, that means you ate a whole cake, which is very unlikely. You should have said, “I ate cake”, then it means you ate some cake.

Notice how the use of the article “a” means that the noun it precedes is countable, and therefore you’re talking about a whole one, an entire one. If you omit the article “a”, then it means that you can’t count the noun it precedes, and therefore you are talking about a piece or a quantity or something. So remember to pay careful attention to whether nouns are being used to a countable or uncountable meaning, and be sure to use or omit the article “a” accordingly.

常见问题

什么时候该用冠词“a”?

当名词在句中表示可数、单数且首次提及的具体事物时,应使用冠词“a”。

为什么“I ate cake”和“I ate a cake”意思不同?

“I ate cake”表示吃了一些蛋糕(不可数),而“I ate a cake”表示吃掉了一整个蛋糕(可数单数)。

名词“dog”前面加不加“a”有什么区别?

“I like dogs”表示喜欢狗这种动物;“I like a dog”指喜欢某一只特定的狗;而“I like dog”在英语中会被理解为喜欢吃狗肉。
