资源简介 小升初英语总复习精讲精练之冠词(一) 不定冠词&定冠词 【精讲】 ???? ?冠词分为不定冠词、定冠词以及零冠词。顾名思义,不定冠词具有不特定、不特指的性质,就是英语中最简单的两个词a、an,这两个词的共同点是:数量上都代表“一个”(人或物),但不特指“哪一个”。而这两个词的区别是:如果后面所跟的词首发音(音标)为元音发音,这个名词前用an,例如:an orange, an egg… ;反之,如果后面所跟的词首发音(音标)为辅音发音,这个名词前用a,例如:a teacher, a park…。在这里要特别说明的是,单词首发音≠单词首字母。 我们一起看看下面的例子: ????a university:这里的university首字母虽然是元音字母,但是字母u的发音为[ju:],首发音[j]为半元音,视作辅音发音功能,所以university前用a。 ??? ? ?an hour:?这里的hour首字母虽然是辅音字母,但是首字母h不发音,所以整个单词的发音为[au?],首发音为[a],为元音发音,所以hour前用an。 ? [小窍门]?我们在上文中用university举例,有的同学不禁要问:是不是所有以字母u开头的单词,前面都得用不定冠词a呢?在这里教给大家一个辨别方法,如果单词首字母u发字母本身的音[ju:],那么这个单词前用a,如?a unit, a university student等;如果单词首字母u发音为[?],那么这个单词前用an,如an umbrella, an unusual day等。 ? ? ? ?说完不定冠词我们再说说定冠词。定冠词,就是我们最常见的the,从字面理解就是具有特定、特指的作用。 在小升初考试中,经常会考查学生在哪些情况下使用定冠词the,这也是冠词中最主要的考点,详见下表: 必须出现the的情况 例句 用于特指某(些)人或某(些)物 Please give me?the? book?on ?the desk. 用于上文已经出现的人或物,再次出现时 I see a dog in?the? garden.?The ?dog?is Cherry’s. 用于说话双方都知道的人或物 Open?the door, please! 用于世界上独一无二的事物 The earth?goes around?the ? sun. 用于专有名词前 The Great Wall?is the?
