1.Why ( )Frank ( )so happy?
A.does,不填 B.does, is C.does,be D.is,不填
我错选了A,正确答案是D.
为什么要这么选?
2 Do you want ( ) e-dog or ( )useful e-book as your birthday present?
A.a,a B.an,a C.an,an D. a,an
我错选了C,正确答案是B。我以为an+A,E,I,O,U打头的字母,可这里后面怎么是a?
2 Do you want ( ) e-dog or ( )useful e-book as your birthday present?
A.a,a B.an,a C.an,an D. a,an
不定冠词的选择依据音标,而不是字母。e-dog首音标(或称为因素)是元音,不定冠词用an;useful首音标是辅音,不定冠词用a。因此选B
