111 Period 5 Grammar The General Idea of This Period This is the fifth period, which will center on the grammar: using the past participle as the adverbial and attribute.At the beginning of the period, the teacher should offer some time to go over what the students learned in the last period. Later the teacher had better present some sentences containing the past participle used as the adverbial and attribute on purpose by asking the students to do some exercises.Get the students to find all the sentences containing the past participle in the two passages.After finding them, the teacher can ask the students to analyze them and understand the function of the past participle in those sentences.While doing it, the students should be given some explanation about how to use the past participle. The following step is to practise more about the grammar.The teacher should arrange some activities carefully and creatively.First let them do some simple exercises.For example, combine the two sentences using the past participle as the adverbial and attribute.Then ask them students to make some sentences using the past participle. Besides that, the teacher should help the students to review the other usages of the past participle.In the end, let them write a passage using the past participle properly. Apart from the usage of the past participle, the teacher had better make the students understand the difference between the past participle and the present participle.In order to have the students master it, the teacher should choose some exercises to supply the students with some problems to deal with.By doing and practicing more, the students may master the grammar. Teaching Important Points To learn about the past participle used as the adverbial and the attribute. Teaching Difficulties To know the difference between the past participle and the present participle. Teaching Aids Multi-media classroom and other normal teaching tools. Three Dimensional Teaching Aims Knowledge Aims To learn about the past participle used as the adverbial and the attribute. Ability Aims To use the past participle used as the adverbial and the attribute freely and properly in speaking and writing. Emotional Aims Encourage the students to study by themselves. Make them know only by doing more exercises can they learn the grammar well. Teaching Procedure Step 1 Greeting　 T: Hello, my friends. Ss: Hello, Miss Wang. Step 2 Revision　 T: Do you still remember what you learned in this unit?Please say something about the life in the future.

S: In the future, equipment will make life much more convenient than now. Ss: ... T: Good.Now please answer some questions according to the passage: I Have Seen Amazing Things. Where did he visit in the first place?What did he find there? S: His first visit was to a space station considered the most modern in this part of space.It is an enormous round plate, which spins slowly in space to imitate the pull of the earth’s gravity. Inside, it is divided into zones with extraordinarily different atmospheres and gravities. There the alien creatures live while they work with human space scientists searching for new worlds. T: Excellent.Would you please describe the friendliest creatures he met? S: The friendliest creatures are the mu-mu, a family from the Pleiades group of stars.They can see in the dark so they live in an area without light of any kind.They have assisted in the discovery of planets round the fourth star in the Pleiades system.They speak in whispers and eat food that contains carbon.They have six arms and one shell-covered leg.They moved forward by slowly shaking from side to side and they are tall and thin with white and black faces. T: You did a good job.What about the most interesting creatures? S: The most interesting creatures are the tiny dimpods from a galaxy near NGC6240.They skip around the pipes and between the wooden walls of the space station.They require the same atmosphere as humans and are great engineers.They will be able to travel many light years away from the earth.They also can produce a special liquid from their bodies.They are not easy to talk to, because you have to use a language-changer to help and they shout loudly in your ear.They are very small with many arms and legs.They are purple or blue and the color changes depending on their mood. Step 3 Presentation T: Can you find the following sentence in the reading passage? Worried about the journey, I was unsettled for the first few days. T: In this sentence the past participle is used as an adverbial phrase.It is a way of joining two clauses together: As I was worried about the journey, I was unsettled for the first few days.Now please pick out three more sentences from the reading passages with past participles used as the adverbial.You are allowed to find as many sentences as possible in two minutes. (Two minutes later, ask the students to report what they have found.) S: Well-known for their expertise, his parents’ company named“Future Tours”transported me safely into the future in a time capsule. S: Confused by the new surroundings, I was hit by the lack of fresh air. S: Exhausted, I slid into bed and fell fast asleep. S: Described as an enormous round plate, it spins slowly in space to imitate the pull of the earth’s gravity. T: Good.You just found all the sentences containing the past participles used as the adverbials.Besides using as the adverbials, the past participles can also be used as the attributes.Can you find the sentences with past participles used as attributes?Finish it in two minutes. (Two minutes later, let the students read these sentences with past participles as the attributes.)
