Period 2 A sample lesson plan for Learning about Language
(Revise the Past Participle as the Attribute， Predicates & Object Complement>)
Introduction
In this period students will be first helped by the teacher to discover and learn to use some useful words and collocations， and then to discover and learn to use the following useful structures: may/ might， can/ could， will/ would， shall/ should， must/ can’t. The following steps of teaching may be taken: warming up by reading aloud to the recording of the text， discovering useful words and collocations， talking about the participle， discovering useful structures， closing down by singing a snake song.
Objectives
To help students revise the Past Participle as the Attribute， Predicates & Object Complement
To help students discover and learn to use some useful words and collocations
To help students discover and learn to use some useful structures
Procedures
1. Warming up by reading aloud to the recording of the text
Do you read aloud to your students？ Do you ever ask your students to read aloud to the recording of the text？
Is there ever a time when students are too old to be read to？ Many teachers are firm believers in reading aloud -- even at the upper grade levels！
Many teachers believe reading aloud enhances classroom instruction and improves academic achievement --- and recent research supports their belief.
Now I am going to play the tape and you are going to read aloud to it.
2. Discovering useful words and collocations
Now it’s time to do the two exercises on page 23. Check your work with your partner.
3. Talking about the participle
The Participle
A participle is an adjective formed from a verb. To make a present participle， you add "-ing" to the verb， sometimes doubling the final consonant:
"think" becomes "thinking"
"fall" becomes "falling"
"run" becomes "running"
The second type of participle， the past participle， is a little more complicated， since not all verbs form the past tense regularly. The following are all past participles:
the sunken ship
a ruined city
a misspelled word
Note that only transitive verbs can use their past participles as adjectives， and that unlike other verbals， past participles do not take objects (unless they are part of a compound verb).
Past Participle
To form the past participle of a verb， add the ending -ed to the base form. (But note that many common verbs have irregular past participle forms.) The past participle is used in the following circumstances:
＊After the auxiliary have in the perfect tense
Has the gas chromatograph been fixed yet？
＊After a form of the auxiliary be in the passive voice
The gas chromatograph was fixed on Monday.
＊After the verbs have and get with a causative meaning
We had the gas chromatograph fixed last week.
＊As a passive participial adjective
The recently fixed gas chromatograph is broken again.
4. Discovering useful structures
You are next to do the exercises 1， 2， 3， and 4 on page 23 and 24.
