If you take my advice on ABC, this is what I would advise on Advertisement:-
When you tell somebody about something in listening test paper,you should try speak a lot and ask students to mark down notes for their answers.
----Tell the students about ABC Co.eg:-an advertising Co.(ABC)
----ABC is doing the business of encouraging people to buy goods by means of advertisements.
----They may have a campaign outside to society.
----They may make something for sale, services offered; divided rooms to rent;,a house to sell or buy.
----They may put it in a newspaper,Daily News SCMP; on television
May have a very big poster advertising "Cosmetic Angel Water Bottle" hanging in Causeway Bay.
----May be Lawyers and Chinese Medicine man to advertise their services in the shop windows;(It may be illegal if allowed?)
----Lemon Tse, the famous film star, is asking students to join his Advertising Co. for a very high salary.Students can interview him at Sept 1st.in his office.
--- Teacher to Students:-Now students failed their tests are given E grade;(From A----E grades).Best of wishes.
