Task 1. Sort the words into three columns: Shop, station, church, street, Chinese, cinema, chair, cash, change, ceiling, shelf, short.

[ʃ]: shop, station, church, cash, change, shelf, short.

[tʃ]: Chinese, chair, change? Actually “change” begins with /tʃ/; include it here. For an unambiguous sorting by initial sound: /ʃ/ — shop, station, church, cash, shelf, short; /tʃ/ — Chinese, chair, change; /s/ — street, cinema, ceiling.

Correction: “station” begins with /s/, not /ʃ/. Final groups:

[ʃ]: shop, church, cash, shelf, short.

[tʃ]: Chinese, chair, change.

[s]: station, street, cinema, ceiling.
