不定冠词a/an的基本用法:

1.表类别,即指一类人或一类事物。

A cat likes fish.(不定冠词+单数名词表示一类)

=Catslike fish.(复数名词表示一类)

猫喜欢吃鱼。

2. 泛指某一类人或物中的任何一个。

Tom bought a new car last week.汤姆上个星期买了辆新车。

3.表示数量的“一”,但其数的概念不如one 强烈。

Give me an apple. 给我一个苹果。(重点在 apple,不要梨、桔等)

Give me one apple. 给我一个苹果。(重点在 one,不要两个或三个)

1.凡属前面可加不定冠词 a(an)或其相应代词(如 another用an的特殊名词100个,one,every,each)并能用于复数形式的为可数名词,如:(a) boy,(another) book,(every) house,(each) day。if you have a tv with a 120hz refresh rate that is 1080p/24 compatible (1920 pixels across the screen vs 1080 pixels down the screen, with a 24 frame per second rate). the tv ends up displaying 24 separate frames every second, but repeats each frame according to the refresh rate of the tv. in the case of 120hz, each frame would be displayed 5 times within each 24th of a second.。 (hertz). for example: a television with a 60hz refresh rate represents acomplete reconstruction of the screen image 60 times every second. as a result, this also means that each video frame (in a 30 frame per second signal) is repeated twice every 60th of a second. by looking at the math, one can easily figure out how other frame rates relate to other refresh rates.。

I go to the cinema once a month. 我每周看一次电影。

5. 用于序数词前表示“又一”、“再一”。

We'll have to do it a second time. 我们得再做一次。

She thanked him a second time. 她再次向他道谢。

Shall I ask her a third time? 我还要问她一次吗?
