G:We'd got 5 low berths, 5 upper berths and 5 middle berths. I suggest that the young men among us take the upper berths, leaving the low berths for the elderly and the two women with little children. The rest of us can take middle berths. What do you think? T:That's a good idea. TA:I'm very sorry, but I get trainsick. Would it be possible for me to take a low berth? TB:Miss Li, please let him have a low berth. I can take an upper berth. Although I'm no longer young, I'm in very good health. Climbing up to the upper berth won't be a problem for me.
