Period 3 & 4 Learning about Language, Using LanguageTeaching Goals:1. To discover the useful words and expressions in the text.2. To learn and improve the use of useful words and expressions.3.

Using Language 1.Pair workAsk Ss to read the text again and make a dialogue with their partners to describe the life of one space creature. Ask one or two pairs to read the dialogues to the whole class. And then let Ss discuss them and see which group do a better job.Sample dialogue:S1: Our space creature is called a moddock. It comes from a planet going around a star on the outer part of the Andromeda galaxy. To begin with we thought it would be impossible to talk to this creature. It used to run away and hide whenever we came near. However, my friend thought of a good way to make friends with it. S2: I noticed that it always looked up when oil was near. SO I thought maybe it could smell the oil so I covered myself in oil and went near. The moddock did not run away but came close to sniff me. S1: Once we knew that an oil smell was the way to make friends with it, everything was much easier. S2: It would put one of its six hands over your face and feel the lip movements. Then it remembered them and watched your face. We found it could speak our language very quickly and soon we were having long conversation s. They re marvelous language learners. 2. Writing Ask Ss to draw a picture of their aliens and then write an essay based on their pictures. At last let them read it to their partners.Sample writing:The moddock is an alien from the Andromeda galaxy. It is shy until you get to know it. To make friends you need to cover yourself in oil as that is the thing the moddock likes best. It should be able to help you with your English homework because it is such a marvelous language learner! It stays in one place most of the time as it finds moving so painful. When it has to move, it rolls over and over like a ball. Moddocks live alone and never go to school. They dont need to, as they are good observers and quick learners from others. It really likes humans and as we are now friends, it wants to become a human being too.Step 3. Discovering useful structures1. Individual workGive Ss two sentences in which the past participle is used as an adverbial phrase. Eg Worried about the journey, I was unsettled for the first few days.Then ask Ss to find other three sentences from the reading passage with the past participle used as the adverbial.(1) Well-known for their expertise, his parents company(2) Confused by the new surroundings, I was hit by the lack(1) Exhausted, I slid into bed Lets Ss discuss the usage of past participle and find some grammar usages.2. Explanation of the grammar.(1) 和现在分词一样，过去分词或过去分词短语也可以充当副词，修饰谓语动词。过去分词可以表达下列四种意思： 方法或活动方式，如：He walked up and down, lost in thought I sat before the desk until after mid-night, absorbed in writing. Surrounded by a host of fans, the film star left the airport excitedly . 原因，如：Greatly disappointed, some staff decided to leave the place. Taken by surprise, the enemy surrendered. 时间，如：Born and bred in a turbulent age, the older generation of people experienced all sorts of hardships. Thrown to the floor, the boy regained his footing a few minutes later . 条件，如：Given more time, the slow learners would have done better . Criticized by someone else, Tony would not have fared up like that. (2) 除了直接修饰动词之外， 过去分词或短语也可以和连词组成短语，表示下列四种意思： 由 when ,whenever , while until等连词引导，表示“时间”，如：When asked about his previous job, Bill said he had been a motor mechanic. Susan seldom speaks in class until spoken to. 由where , wherever 连词引导，表示“地点”。Mosquitoes should be completely exterminated where found. Retires in good health should be invited to return to work wherever needed. 由if , unless引导，表示“条件”，如If kept for too long, some medicines will lose their effectiveness. We have made a point of not attacking unless attacked. 由 though, although , even though 连词引导，表示“让步”，如：Though warned of the danger, they still went mountaineering. Even though defeated for a second time, our team did not give up hope for the ultimate victory. IV Studying the past participle as the attribute. (3) 过去分词做定语, 在语态上表被动，在时间上表示动作已经发生或完成，与它所修饰的名词有逻辑上的动宾关系。 过去分词做定语时， 所修饰的名词在逻辑上相当于被动句中的主语，过去分词相当于谓语。 (4) 过去分词作定语表示动作在谓语之前发生，已经完成并具有被动意义。有时也不表示时间性。作定语的过去分词一般由及物动词变来，因为只有及物动词才有被动意义。如：He is a teacher loved by his students. 他是个很受学生爱戴的老师。 (5) 也有不及物动词作定语的情况，一般作前置定语，它不表示被动意义，只表示主动意义，强调动作完成。不能像及物动词的过去动词那样放在名词后面作定语。如： fallen leaves, retired workers , the risen sun 注意下面过去分词作定语的几种情况： 单个的过去分词作定语一般放在被修饰的名词之前。如：We needed much more qualified workers My friend is a returned student. 过去分词短语作定语要放在被修饰的名词后面，作后置定语，其作用相当与一个定语从句。如：The student dressed in white is my daughter = The student who is dressed in white is my daughter. 如果被修饰的词是由every /some/any / no+thing /body/one 所构成一个复合代词或指示代词those 等时，即使一个单一的分词做形容词，也要放在被修饰词的后面。例如：Is there anything unsolved?There is nothing changed here since I left this town. 单个过去分词前加一名词或副词，常用连字符将它们连起来构成一个复合形容词，放在其修饰词前，作前置定语。This is a state-owned factor. This is our school run factory. 作前置定语的某些动词的过去分词的形式与作谓语或表语的过去分词的形式往往不一样。例如：原形用作定语的过去分词用作表语或谓语的过去分词 drink drunken drunk light lighted lit melt melten melted sink sunken sunk We lit the candle and the candle lit up the room. 我们点着蜡烛，蜡烛照亮房间。There is a lighted candle on the table. 桌上有一只点着的蜡烛。2. Pair work(1) In pairs combine these two sentences using the past participle as the adverbial. I was frightened by the loud noise. I went to see what was happening. _ He was hit by the lack of fresh air. He got a bad headache._ I felt very tired after the long journey. I still enjoyed meeting the aliens on the space station._ The little girl was frightened by the noise outside. The little girl dared not sleep in her bedroom. _ The museum was built in 1910. the museum is almost 100 years old. _ The student was given some advice by the famous scientist.
