歌曲it might be you里的英语句子的问题
Time
I've
been passing time watching trains go by
All
of my life
Lying
on the sand,watching seabirds fly
Wishing
there would be someone waiting home for me
Something's
telling me it might be you
It's
telling me it might be you
这句子里lying ,watching,wishing的用法一样吗?是现在分词还是动名词呢?
All of my life
Looking back as lovers go walking past
All of my life
Wondering how they met and what makes it last.
这里looking和wondering的用法又是什么?是现在分词吗
