高中英语冠词易错点
The boss wants to hire an useful person.
用a还是an,取决于后面单词的个音标,如为元音用an,为辅音用a。useful的个音是辅音所以应把an改为a。类似的,我们说a European country.
8. Plane is a machine that can fly.
Plane为可数名词单数,不能单独放在句中,应在其前加冠词或把它变为复数,而本句后有a machine, 因此只能在其前面加a,变为A plane。
9. He played a piano at the party yesterday.
把a 改为the ,因为乐器前用定冠词。
