英语冠词的用法
个人认为冠词还是比较容易的,这类题做得多了,就有语感了
an icy rain 肯定是泛指啊,
一场冰雨,不需要是那场冰雨
the road 是特指,冰雨fall 的路上
在一次对44项研究的回顾中...这里的表示泛“在一次...”的意思,并没有说清楚是在哪一次一次以及时间等重要的含有特别指定意味的,所以应该用“a”;
如果第一句用the的话,翻译过来就是“在那次对...的回顾中”,但是后面的of 44 studies表示的虽然是对review的修饰,但是讲的并不具体,因为In a review of 44 studies的这种情况太多了,所以这里泛指,不能用the.
第二句中“prevent ()spread of AIDS”翻译为:防止艾滋病的蔓延,其中艾滋病的表示的是独一无二的,特指的,由他来修饰当然要用“the”.
看用不用加the,其实很简单,用the的名词一定是说话者和听话者(或者写文章的人和读文章的人)都知道的东西或事情
比如,
I bought a book and i like the book a lot.
我买了一本书,我很喜欢那本书.(你要翻译成“我很喜欢“这本书”也可以”,其实都是指前面说的那本书)
The sun goes around the earth
太阳绕着地球转.(我虽然前面没有提过,但是全世界就只有一个太阳和地球,用the不会有歧义)
而你说的那个题目:
如果你说Polar bears live mostly on the sea ice
而sea ice-“海上浮冰”,全世界并不只有一块儿,是所有的浮冰的一个宽泛概念
如果你对我说这句话,就意味着,我原先对你说的那块儿“海上浮冰”了如指掌,知道它的位置,大小,等等,好像你是想表达:“北极熊通常都是在那块儿(我知道的那块儿)浮冰上生活的.”这显然是个奇怪的说法
因此,就不用the,表达泛指的“浮冰”概念,“北极熊通常都是在浮冰上生活的”
冠词是一种虚词,用在名词或名词词组的前面,表示名词是特指还是泛指.冠词可分为不定冠词和定冠词两种形式. 不定冠词有 a, an. 定冠词有 the. 其中, a 用在发音以辅音开头的名词之前, 而 an 则用在发音以元音开头的名词之前.
