It was a hot summer day. My mum 14 (hold) a small note and waving at every taxi that passed along the Suzhou road. We had come here by train 15 Shanghai to visit the classical gardens. But now we had already been standing by this road for over 16 hour. We needed to go to the station to catch 17 (we) train to Shanghai and had asked a local shopkeeper to write down the name of the station for the driver to understand. But every driver who stopped to examine the note drove off without 18 (say) a word. There we were, helpless and 19 (lose) in China.
Luckily, a young lady walked over and found out that the paper only said “xièxiè” —Chinese for “Thank you”. No wonder no one would take us. We 20 (sudden) realized that my father had repeatedly asked the shopkeeper to “write this down, please. Thank you! Thank you!” Apparently, he had assumed us funny foreigners 21 wanted to know the word for “thanks” in Chinese. That explained the 22 (puzzle) expression on the taxi drivers’ 23 (face) as they just read “thank you” on the note. Thanks to the help of the passer-by, we were eventually able to catch the train.
