check the homework.t: id like to know what your inventions that you will see in the future are. whod like to share your ideas with us? please read your writing about it.s: most of us came to school by bike. some of us sometimes have a bike stolen or find it difficult to find room for parking the bike. so i think if there were a new invention that would be named inflatable bicycle, we would never have to worry about having our bikes stolen and finding suitable space to park our bikes. and if we dont use it, we can let the air out and put the bikes in a bag. it would be very convenient.t: a wonderful idea. what else?s: my invention is a device that translates chinese into english. it is very important for people who come from different countries to communicate with each other. it is made up of a 3-inch long wireless microphone that is fastened to a tie and sends out sounds to a small console that is connected to a database. the console can translate chinese into english, so by that time chinese can communicate with foreigners who know english fluently. t: excellent! i hope that you must study hard and try to realize your dreams. maybe some day some of you will be inventors.step ii grammar get the students to learn to use the future perfect and the future continuous correctly.t: we have learned some ways to express the future. they include “will / shall do”, “be going to”, “be to do”, present progressive “be doing” and simple present “do”. now look at two sentences with the future tenses on the screen. in which of these sentences do we emphasize that the underlined activity must be finished before the other one happens?show the following on the screen.1 when you get home on friday, youll receive good news.2 after youve done the shopping, youll have a pleasant surprise.ss: in the second sentence, we emphasize that the underlined activity must be finished before the other one happens.t: good. lets look at another two sentences on the screen and pay attention to the parts in bold. then point out which of the tenses refers to something that will finish before a certain time in the future and which refers to something that will be in progress at a certain time in the future.show the following on the screen.1 by the end of the century, we will have discovered other places in our solar system 2 at nine oclock on saturday morning, ill be sitting in the front row and listening to the great professor willard.ss: the tense in the first sentence refers to the activity “discover” that will finish before the end of the century, a certain time in the future. and the tense in the second one refers to the activity “sit” that will be in progress at nine oclock on saturday morning, a certain time in the future.t: you are right. the two tenses are what we are going to learn today. now look at the screen.show the following on the screen.1 the future perfect: will / shall have done2 the future continuous: will / shall be doingt: the construction “will / shall have done” is used when we want to express an action that has just finished before a given future time. the tense is called the future perfect. the construction “will / shall be doing” can be used to denote an action that is happening / going on at a given future time. now please find more examples of the two tenses in the text on page 20.suggested answers to exercise 7:1 the seminar
