选定冠词
解题思路: 如下
解题过程:
冠词的用法
一.冠词的种类:
1. 定冠词: the
2. 不定冠词: a / an
当紧跟不定冠词之后的单词是辅音发音开头时,不定冠词应该用a, 当紧跟不定冠词之后的单词是元音发音开头时,不定冠词应该用 an.。
a + [辅音……] a wallet, a European country
an + [元音 …… ] an hour, an 8-year-old boy
一般说来,冠词应放在名词或名词词组的最前面.
a matter, an easy problem, a necessary action, the world, the old stone bridge,
注意:在以下六种词中,只能使用其中的一种词修饰名词:
冠词、指示代词(如:this, that, these, those)、形容词性物主代词(如:my, your, his, her等)名词所有格(如:Tom’s, the Smiths)、不定代词(如:every, each, any)以及疑问代词(如:which, what).

5.每隔几天一次 (不能说:once every a few days) once every few days
三.冠词的用法
1.a / an 表示数量 “一”,但不强调数量 “一”.如果强调数量“一”,应该用one.请比较:

(想告诉别人: “我”有兄弟,虽然提到了 “一个”,但想强调的是 “我”不是独生子女,或想强调的是 “我”不是有姐妹.)
I have only one brother.
(想告诉别人: “我”并没有两个、三个兄弟.)
2.不表示数量 “一”,而是表示类别,可以在单数可数名词前加a /an.

One can not live without air or water.
3.对于说话者特指但听话者还不知的单数可数名词(人或物),第一 次提到时,前面经常加a / an;再次提到才加the,这时,说话者和听话者都知道是特指哪一个人或物.

5.在最高级副词前可以加the,也可以不加the;在最高级形容词前 一般要加the; 但是, 如果不表示 “最”, 而是表示“非常”, 则应 在最高级形容词前加 a / an,
