5、th some exercises including some word study.The teacher may show them on the screen,such as staple,yield,sterile,hybrid,etc.By guessing from the whole context they will have a good sense of enlarging their vocabulary and this is very important in learning a language.While reading this passage,some r

6、eading strategies are necessary:skimming fast reading to find out the general idea of the passage as well as the answers to one or two questions;scanningcareful reading to look for important facts;guessingtry to guess new words from the context,understand the author s attitude and ideas from the con

7、text and understand the intention.In the teaching of reading,the teacher can organize different reading activities according to the content of the text on purpose to train the above reading strategies and help them develop good reading habits from the very beginning.Function Function in this module

8、is talking about numbers,which include big numbers,fractions and percentages.The students can finish Activities 1 and 2 individually and check the answers with the whole class.As for activity 3,pair work or group work is better.Let the students dictate some numbers to their partners to consolidate w

9、hat they learned.After that,the teacher can give them a quiz to make sure the students can distinguish different numbers correctly and can read and write them in the correct way.Grammar 1 In grammar 1,we ll revise the passive voice of present tense,past tense,future tense and present perfect tense.T

10、here are four activities for the students to practice.Through Activity 1,the teacher will know if the students can tell passive voice from active voice and if they can distinguish the sentence tense.In class,the teacher should give the students more chances to speak English.Listening Activity 1 is a

12、es 2 & 3 more efforts may be involved,and therefore the teacher had better play the tape twice.After listening we ll do a word exercise,that is Activity 4,match the words with the meaning.It is a good way to consolidate new words.Reading and Writing This part is very important and useful for the stu

13、dents to practice writing.At the beginning,we ll learn the new words:best-seller cosmology,diagnose,disability,motor neurone disease,and victim.In activity 2 there are three disordered paragraphs about scientist Stephen Hawking.Then make sure the main idea of each paragraph in activity 3.Activity 4

14、gives us the notes about Albert Einstein in the order of time,which is often the main character of introducing a person.At last,choose some information about him to write three short paragraphs about Albert Einstein.The beginning is given in Activity 5.Time permitting,the teacher may encourage the s

15、tudents to report what they write.If possible,present the students writing on the screen.Mistakes can be corrected now.Grammar 2 In this part,the students will learn to use by+-ing form.Firstly,in Activity 1 make sure the usage of this form.It usually works as adverbial,and means “ using some way” .

16、This form is not difficult.We are sure that after the practice in Activity 2,the students can master this form correctly.Pronunciation;Speaking and Everyday English The stress in long words is also the emphasis.The stress in a long word maycome at the beginning,in the middle,or at the end.In this pa

17、rt,we ll do some practice about that.In speaking,we ll play a game of guessing scientists names.First,the students may think of a famous scientist or inventor and some information about his life.Some questions about scientists are given as examples.Then work with another pair.Guess who pair B is des

18、cribing by asking yes or no questions.Pair work will be involved in this part and more practice will be encouraged.Everyday English we ll learn in this module is as follows:breakthrough,nickname,Pass and well done.Cultural Corner In this part,we ll learn something about rockets.After studying the te

19、xt,the students will be clear about the history and development of rockets.This supplementary reading will enrich the students knowledge of some scientific invention.Task After speaking,write down your notes about the scientist.Then prepare a radio programme about the life of a famous scientist.If p

20、ossible,record your radio programme.If not,write a passage about the famous scientist,and then report it to the whole class.Module File This part is a summary of this module.It may help the students to know whether they have mastered the main points or not.If time permits,the teacher may have a revi
