Before you listen, look at the pictures and guess whether they would be useful for astronauts in space.
The most useful items by far in space would appear to be the tape and the tissues. Both are light and do not take up much space, and neither of them can cause a mess which is difficult to clean up.
A: I wonder how they get exercise in space—it’s not like they can go out jogging.
C: I’d never thought of that. But then, after they exercise, I’m very keen to find out how they wash their clothes.
I’m most curious about ...
I’m most interested to discover ...
I’m very keen to know ...
I wish to know ...
I hope you won’t mind me asking about ...
