好像要表示整个类属习惯上是用定冠词加单数名词的吧,应该是不能用复数名词或用单数名词连用不定冠词的。比如:
老虎有灭绝的危险。
正:The tiger is in danger of becoming extinct.
误:Tigers is in danger of becoming extinct.
误:A tiger is in danger of becoming extinct.
但是下面这句怎么解释呢?
Internation measures have been taken to prevent the extermination of whales. 国际上已经采取措施防止鲸鱼灭绝。
▲你的句子完全正确:
Internation measures have been taken to prevent the extermination of whales. 国际上已经采取措施防止鲸鱼灭绝。
▲表示整个类属不仅可以用定冠词加单数名词,也可以用复数名词,但不能用单数名词连用不定冠词。即:
老虎有灭绝的危险。
正:The tiger is in danger of becoming extinct.
正:Tigers is in danger of becoming extinct.
误:A tiger is in danger of becoming extinct.
