u在单词中能发什么音(为什么U开头的单词前面有时加a)

上一讲我们讲了冠词的泛指、定指、量指和独指,今天简单地复习一下。我们知道学习冠词不仅是要记住什么词前面加什么冠词,还要理解什么是泛指、定指、量指和独指概念。例如:

Do you like art? 你喜欢艺术吗?(泛指)

Music is an art. 音乐是一门艺术。(量指)

Government funding for the arts has been reduced. 对艺术这类学科的投入(定指)

Fresh water is scarce in some countries. 淡水缺乏 (泛指)

The flowers want a poured water. 浇透一次水(量指)

He jumped into the water to save the boy. 跳入(落水的)水中 (定指)

u在单词中能发什么音(为什么U开头的单词前面有时加a)(1)

下面我们做几道高考冠词真题,以巩固冠词的知识。

(1. 2018 I) Corn production has jumped nearly 125 percent over 62.________ past 25 years, while rice has increased only 7 percent.

(2. 2018 II) Unexpectedly, I'm face-to-face with the gorilla, who begins screaming at 62.________ top of her lungs.

(5. 2011 广东) I sat next to the man and introduced myself. We had 24.________ amazing conversation.

解析:1. over 62.___the___ past 25 years 过去的25年, 定指;

2.screaming at 62.___the___ top of her lungs 撕心裂肺地尖叫, 最大的声音,定指;

3.As 65.___a_____ result,结果是,只有一个结果,量指;

最后谈谈an的用法,虽然全国卷还没考过,但也得掌握。

我们知道,不定冠词a与an在意义上没有区别,a用在辅音音素开头的单词或字母前;an用在元音音素开头的单词或字母前,而且要与后面的单词连读(连读用下划线表示)。如:

an important meeting, an elephant, an old woman, some envelopes

这与语音知识有关,要弄清楚元音音素有20个,元音字母a, e, i, o, u共5个, 其中u有两种拼读音,所以要特别注意以u开头的单词。如:

u在单词中能发什么音(为什么U开头的单词前面有时加a)(3)

ugly, umbrella, unable, uncertain, uncle, underground, understanding, underwater, undivided, unfair, unfolded, unhealthy, unknown, unlike, unpleasant, unreserved, unrest, unsold, unsuccessful, unusual, upstairs, upward。

还有一些辅音字母也是元音音素开头,加冠词时要加an,如:
