Unit 4 Then and now
Grammar time & Fun time
译林牛津·六年级上册
When I was young
I’d listen to the radio
Waiting for my favorite songs
When they played I’d sing along
It made me smile
Those were such happy times
And not so long ago
How I wondered where they’d gone
But they’re back again
Just like a long-lost friend
All the songs I love so well
…
It’s yesterday once more
Let’s sing together
