I believe students may have the following difficulties in taking IELTS listening test.

1. Speaking is too fast, especially when weak forms and linking sounds are involved, which is actually a very common phenomenon. 

2. New words, or collocations very idiomatic but not familiar to Chinese students, such as "prescription glasses/ goggles/ a naked flame"

3. Abrupt turnings or negations in logic could be very misleading or disturbing. eg. "yes, it is very useful for finding a job. But i have a job right now." 

4. Numbers with confusing sounds, like sixteen and sixty.

5. there could be some confusing choices. eg. 

21. Students must follow ............. to prevent accidents in the lab.

…if you always use your judgement, observe safety rules and follow directions

I hope i can organize each of my lessons with focus on one difficult language phenomenon. it will be highly appreciated, if this training programme can provided such materials.
