I ______ (not) come shopping with you tomorrow – I’ve got a dental appointment.

I’m really pleased to hear that you could come to visit me next month.

Although the shop was very crowded, we could / were able to get the shopping done quite quickly.

A lot of unique markets could be found in London.

We could find our way around Rome easily by using online maps on our smartphones.

I was very happy that I could meet all your friends when I visited you last month.

When I was a small child, I could / was able to sing beautifully, but my voice isn’t so good now.

It would be much easier if we can find the information on the internet.

I could buy / could have bought my tablet more cheaply online, but I got it from my nearest independent computer shop instead because I like to support local businesses.

Even though we were cold and tired, we could / were able to reach the top of the mountain.

I can’t carry everything, so I had to leave some things behind.

I’d be grateful if you can advise me about which book to buy.
