T: Hello, my friends. Ss: Hello, Miss Wang. Step 2 Reviewing the Grammar: the Past Participle  T: Complete each sentence by choosing the right verb and putting it in the correct form.‎

answers to the whole class.If they still have difficulty understanding, the teacher should offer some explanation.) Suggested answers: ‎ ‎1.connected　2.folded　3.carried　4.mentioned　5.intended　6.lost　7.Frightened　8.Given T: Now let’s have a competition.Use these sentences to make up a story.If necessary, you can change the expressions of the sentences.You had better make your story interesting and complete.　If you can properly use the past participles in the story, there will be more chances for you to win the competition.First discuss making up a story with your partners, then tell your story to another pair near you.Later combine your story with another pair’s to make up a new story, which must be better than the first edition of your story.In the end, tell the whole class the story which has been made up by your group.Let’s see which group will do the best. ‎(The teacher will give them five minutes to make up a story.After that, let volunteers show their story.The group will be the winner if they can tell the most interesting story and expressions are very fluent without mistakes.After the competition, the teacher had better praise the winner, and encourage the others to try to succeed next time.) Step 3 Learning about Words and Expressions T: What did Li Qiang not believe? S: He can’t believe that he is taking up his prize that was won last year. T: Right.What does“taking up”mean in the sentence? S: Start or begin something. T: Yes.Taking up means starting or beginning something, especially a job.For example, “She takes up her duties next week.In fact, it has many meanings.” take up 开始做（工作）; 占用; 选修; 从事; 打断了某人的话（以反驳和批评）; 提交议论等。 例如: ‎ When does the incoming manager take up his job? 新来的经理什么时候开始工作？ The copying of these documents took up the whole morning. 复印这些文件用了一个早上的时间。 He has taken up art in college.他在大学里学习艺术。 The table takes up too much room.这桌子占了很大空间。 She took me up

do T: Good.remind somebody of something是指“使某人回忆起过去的事情”。而remind somebody to do something是指“提醒某人去做某事”。例如:  ‎1.It reminds me of what a woman once said of him. ‎2.Remind me to take my medicine tomorrow. ‎3.Mrs.White reminded her son to go to the store after school. T: Can you use it to make some sentences? S: 1.Her appearance reminded me of a childhood friend of mine. S: 2.I forgot to

phrase“as a result”?‎ S: as a consequence T: Yes.“As a result”is almost the same as“as a consequence”.For example: He worked hard, and as a result, he got promoted quickly. ‎ He used to be lazy to read English, as a result, he failed to pass the examinations again and again, which led to his failure to go to college. T: Do you still remember some other phrases related to“result”? S: as a

them. S: Put on this mask. S: If you to there, you must wear red nightlights on your helmets so that you can see. T: From these two sentences, we can know the difference between them. Put on指穿的动作,

flower to attend the party.‎ T: Pay attention to other phrases; wear out使……破损或使人筋疲力尽; wear somebody/　something down削弱; wear off变弱; wear on 指时间慢慢消逝 Children’s shoes are worn out. She wore herself out walking home with the heavy bags. T: There are some other expressions which have the similar meanings to“wear”.Have on, be in, dress, be dressed in.‎ T: Can you use them to make some sentences? S: He is old enough to dress himself now. S: She used to be in white when she was young, while she likes to be dressed in red now. S: A little boy suddenly cried out, “He is having nothing on.” S: Doing the same thing day after day makes her worn out. S: This morning, he got up late and hurried to put on his clothes, and as a result, he is wearing his clothes in disorder. T: Excellent.Now, let’s look at the screen together to learn more expressions.(referring to the following material) Step 4 Learning Some Sentence Structures T: Now let’s learn some sentence structures.Can you find the following sentence in the passage?Can you translate it into Chinese?“Confused by the new surroundings, I was hit by the lack of fresh air.”‎ S: 新的环境把我弄得心烦意乱的, 由于缺新鲜的空气, 我感到受不了。 T:

comfortable for first few days. S: He worked day and night, tired but excited. S: The girl likes sitting in her study, lost in thought. T: Good.Would you please find the sentence and understand

flashed a switch on a computer screen, and a table and chairs rose from under the floor as if by magic.”Please transform it into Chinese. S: 王平的母亲出现了, 电脑荧屏上的开关闪了一下, 于是一张桌子和几把椅子就像魔术般地从地板下面升了起来。 T:

you.Here“what looked like a large market”is used as an object.For example,‎ Work hard and you will be able to obtain what you are expecting one day.Let’s make some sentences belonging to object clauses with“what”.‎ S: Do what I asked you to.‎ S: They reached what they thought they had been dreaming of. S: What we haven’t got seems much better than what we have got. T: Wonderful sentences.“in all directions”is“从四面八方”in Chinese.For example, Hearing the noise, all birds on the trees flew in all directions.Then how to understand“because of the people flying in all directions? S: Because of + something/doing something. T: Right.There is some difference between“because”and“because of”.As a result, because of the people flying in all directions = because the people were flying in all directions. T: Please pay attention to the next sentence:  Neither of these creatures is easy to talk to.What does that sentence mean? S: 跟他们俩交谈都不容易。 T: Right.在英语里有些形容词如: easy, hard, difficult, impossible 当它们用作表语时, 其后的动词不定式, 如与主语存在语意上的动宾关系, 通常用主动形式, 而不用被动形式。For example,  The horse is impossible to control. The problem is not easy to deal with. Have you understood it?Now let’s finish the following sentences. This room is... English is... S: The room is hard to clean, because it is too dirty. S: The room is comfortable to live in. S: English is difficult to learn

many farms now use computers to control the growing conditions of vegetables and other plants.In glasshouses, computers control the watering of the plants as well as the light and the temperature.It is possible to work out whether you will save or lose money by increasing the temperature by ‎1℃‎.‎ In their personal lives people will also use computers more and more.Instead of going to the bank, they will use a computer and a telephone to change money and to pay their electricity bills and so on.Houses will be controlled by a central computer.Lights will go off if no one is in the room.The idea that computers can recognize human voices surprises many people.You will be able to telephone home half an hour before returning and, by speaking into the telephone, you will be able to tell the computer to turn on the heating and the hot water.The computer will recognize your voice and carry out the instructions.‎ The possibility that the majority of the labor force will work at home is often discussed.It will be much more convenient than spending a lot of time traveling to work every day.People will be able to use the videophone for conferences.They will be able to do drawings and send them by mail or by fax.‎ Computers will be used more and more in transport.Railways in Japan already use them to work out the best distance between trains.Trains will be operated by computer and many of them will have no drivers.‎ Space travel will become much cheaper.In ‎1993 a new space rocket with no wings was developed in the USA.This type of rocket is able to return to the earth and land on its legs.As a result, costs will be reduced by as much as 90%. In the fields of education, health and research, computers will continue to play an important part.It will be part of everyone’s education to learn computer skills.Information records, for example, of patients with the same illness, are now kept on computer.It is possible to have a group of these records collected and printed.Computer programs for storing while texts are already well developed.You can type the name of a subject, e.g.“Printing in China, ”and the computer will give you a worldwide list of magazine and book titles.The next step is to search the title for more information.Finally you can choose certain texts and read them on your computer screen.If you want a copy of the article or page, it can be printed out and sent to you.
