不定冠词的特殊位置有哪些作者: admin来源: 网络文章时间: 2019-03-06我在实际使用的过程中不难发现，不定冠词总是置于被修饰名词前，若名词前有其他修饰语，则不定冠词通常要置于该修饰语前。但是，还是存在一些比较特殊的情况，以下这几点我们需要格外注意。一、与such和what连用时不定冠词与such, what连用时，习惯上是置于它们之后，而不是之前。such aShe is such a good friend. 她是那么好的朋友。Such a boat is fit only for a calm sea. 这种船只适合在风平浪静的海上航行。what aWhat a great idea! 多么了不起的主意！What a beautiful diamond ring! 多漂亮的钻石戒指！She told him what a silly boy he was. 她告诉他是个多么蠢的孩子。二、与rather和quite连用时当一个单数可数名词前有rather或quite修饰时，不定冠词习惯上要放在这些词之后。如：rather aIt was rather a pity. 这真是件憾事。It was rather a success. 这件事相当成功。quite aThats quite a problem. 那很成问题。Your daughter is quite a beauty. 你的女儿真是个大美人。但是，当这类结构中的名词还带有形容词修饰语时，则不定冠词既可放在这些词语之前，也可放在这些词语之后。He was rather a a rather naughty student. 他是一个相当淘气的学生。由于名词student前有形容词naughty的修饰，所以既可说rather a naughty student，也可说a rather naughty student。三、与half连用时当不定冠词与half连用时，在通常情况下，我们总是说half a。如：I need half a kilo. 我需要半公斤。He arrived half an hour ago. 他是半小时前到达的。在美国英语中，也可说成a half，如说a half kilo, a half hour等。但是，在某些特殊表达，我们必须要说a half，如要表示“几个半”时，我们总是说and a half。如：I waited for an hour and a half one and a half hours. 我等了一个半钟头。不定冠词知识点总结作者: admin来源: 网络文章时间: 2018-09-01We need an apple and a knife.我们需要一个苹果和一把刀子。1.a和an的区别不定冠词有a+和an+Q两种形式，a用于辅音(不是辅音字母)开头的词前。an用于元音(不是元音字母)开头的词前。a boy, a university, a European countryu是元音字母，但发音是U(，是辅音。an hour ，an honor ，an islandh是辅音字母，但它不发音，它的音标是是元音。an elephant， an umbrella， an egg2(1)不定冠词的用法泛指类人或物。eg.
