1 Is there anything wrong?
No.So far I ______(have)no trouble.
2、Look!Mr Green is ______(lose) in his books.
该填什么，为什么？？？
3、I have got ____ MD Player.Do you have one?
A an B a C the D one
为什么选A
No.So far I ______(have)no trouble.
2、Look!Mr Green is ______(lose) in his books.
该填什么，为什么？？？
3、I have got ____ MD Player.Do you have one?
A an B a C the D one
为什么选A
1 have had
（SO FAR,“到目前为止”,所以用现在完成时）
2 lost 词组be lost in意思是“沉迷于。。。。”
3 A an
后面的MD 发音时，M 是以元音/e/开始的， 所以选A an
就类似于--- an hour
No.So far I __have had____(have)no trouble.
Look!Mr Green is ___losing___(lose) in his books
MD 的M是/em/元音开头
1 have had
2 lost
3 A
1 have
2 losing
3 应为an用于以元音开头的名词前(指发音而不是拼写)
