T: Good. Any more examples with "-er"?

Ss: Writer, organizer etc.

T: (writes down "-er" on the blackboard) What about other noun suffixes?

S: Thomas Edison invented the way of giving electricity. He was an inventor. "-or" is a noun suffix for a person. Another example is "sailor" from "sail".

T: (writes down "-or" on the blackboard) Right.

S: I remember one more suffix for a person. For example, Yang Zhenning has made great contributions to the field of science. He is a scientist. "-ist" is a suffix for a person.

T: (writes down " ist" on the blackboard) Good job. In fact we have one more suffix for a person. For example, if I interview you, you are my interviewee. "-ee" means a person too. ( writes down "-ee" on the blackboard)

3. Practice

1)Check exercise 1 on Page 4. Show the table on the screen and get the students to say the answers aloud in chorus so that everyone will be aware of the suffixes. If they have any questions, give further explanation.

2)Show some more words on the screen and get the students to guess their meanings according to the rules of word formation. They should be able to tell their meanings at the first sight. Instruct them to find out the root first and then guess the meanings of the words, taking the suffixes into consideration.

pianist, typist, physicist, educationalist

protection, imagination, separation, education

punishment, management, statement, requirement, entertainment, payment

prisoner, adviser, lecturer, climber 4. Summary

T: Now we can see it is not really difficult to remember words as long as we master some rules. With the knowledge of word formation, we can enlarge our vocabulary. Today, we focus our attention on the Noun Suffix. In fact there are much more suffixes in English, later we will come across some of them.

Step 3 Discovering useful structures (Subject-verb agreement)

1. Brainstorm　Subject-verb agreement by giving simple examples.

T: Now watch me. What am I doing? (draws a picture on the blackboard)

Ss: You are drawing on the blackboard.

T: Yes. The teacher is drawing on the blackboard. (Writes the sentence "The teacher is drawing on the blackboard". ) What about you? What are you doing?
