Mr. Green, could I ask you some questions please? Excuse me , sir. May I have a look at the name of your book?T: Can you tell me the differences between the three sentences :(PPT)T:- In the 1st sentence, III Simon uses can to ask his friend Kitty a question because it s informal.4can, is always used with friends.(在第句中，Simon 用情态动词，can，提问他朋友Kitty,因为这通常用于朋友之间的非正式场合。)In the 2nd sentence,/Simon uses “could to ask his teacher Mr. Wu a question because it s formal,“could“ is always used with teachers or other adults.(在第二句中，Simon用情态动词，coukT提问他老师，Mr Wif,因为这通常用于教师和其他成年人之间的正式场合。)一 in the 3rd sentence,/Simon uses may to ask a stranger a question because it s formal and polite,may is always used with strangers and people you respect.(在第三句中，Simon用情态动词may提问陌生人，因为这通常用于陌生人和你尊重的人之间的正式而礼貌的场合。)Here pay more attention to “might”. Might is very formal and its very polite but rarely used.(注意：，might的用法既正式又礼貌，但是实际生活中很少使用。) eg: Might I use your computer, Mr. Wu?X They all express permission.(他们都用于表示请求和允许。)T: OK. Let s do some exercises.(PPT)T: Let s check the answers.1 Dad, could I take your camera?Yes, you can .(Its formal.)2 May I borrow this helmet, madam?No, you may not.(Its formal and polite.)3 Can I borrow your boots, Mike?Yes, you can.(Its informal.)T: Can you give me the answers to these questions about can, could, may , might,?(PPT)1 Can / Could you go to the zoo tomorrow?We can answer :-Yes, you can . or No, you cannot/ cant2 May/ Might I use your computer, Mr Wu?We can answer :Yes, you may. or No, you may not/ cant.T: Here could , mighf do not mean 4the past tense, but mean more polite ,.(这儿的“could , might ”不是表示在去时，而是表示更委婉的语气。)T: Now please write sentences to ask for permission in the following situations.(PPT) look at the 1st SituationIf you are on a bus and the person in front of you has the window open and It starts to rain and youre getting wet. How do you ask him for permission?一 We can ask : May I close the window? Because its formal and polite to use may when we ask a stranger on the bus for permission.T: Look at the2nd SituationIf your cousin is watching a boring programme on TV. What do you say to ask her to change the channel.T: We can say:-Can I change the channel? Because its informal to use can to ask friends for permission.T: Look at the 3rd SituationIf your uncle and aunt have invited you to join them in a walk in the park and you want to take your dog with you./What do you say then?That* s right. We can say :Could I bring my dog? Because its formal to use could to ask adults for permission.Step 3 The Object clauses introduced by thatT: Look at Grammar B .Lets learn that 4 clause (下面我们来学习 that 引导的宾语从句。)(PPT)1) Earth is becoming more and more crowded and polluted.What does Daniel think ?-Daniel thinks that Earth is becoming more and more crowded and polluted.2) ) People will live on the planet Mars by the year 2100.What does Daniel think?-Good . Daniel thinks that people will live on the planet Mars by the year 2100.3) The robot will do most of the work.What does Daniel think?一Yes, Daniel thinks that the robot will do most of the work.T: Now can you put these two sentences with that?T: Lets do some exercises.,Have you finished?

Can you find out the rules about Object clauses introduced by that?(PPT)(那么你能总结-that连接的宾语从句的规则吗？)Tips1 We can use that clause to replace an object after the verb in a sentence.(我们可以用that从句来代替一个宾语连接跟在动词后面做宾语。)2 The word order in the object clause is just the same as that in the statement.(从句中语序保持不变。)3 Sometimes we can leave the connective that out in the object clause.(有时连接词that也可以省略不用。)T: It seems terribly easy for you, right? Lets do more practice. Can you join the following sentences with object clauses introduced by that?(PPT)1 ) People think.Humans on Mars have to wear special boots to make themselves heavier.

So ifs N.(在这句中that we need不是宾语从句，因为它不在动词后面。)2 ) Scientists should be able to develop plants that grow on Mars.一Here that grow on Mars is not an object clause because its not after a verb. So its N .(在这句中“hat grow on Mars，不是宾语从句，因为它不在动词后面。)3 ) People think that humans on Mars have to wear special boots to make themselves heavier.Here that humans on Mars have to wear special boots to make themselves heavier* is an object clause after the verb “think.So its O.(在这句中that humans on Mars have to wear special boots to make themselves heavier,是宾语从句，因为它在动词“think，后面。)4 )We all know that Mars is a planet in the solar system.-Here that Mars is a planet in the solar system, is an object clause because its after the verb know.So its O.(在这句中，that Mars is a planet in the solar system，是宾语从句，因为它在动词后面know。)5 ) The journey to Mars could take only a very short time in space shuttles that travel at half the speed of light.-Here that travel at half the speed of light, is not an object clause because its not after a verb. So ifs O.(在这句中，that travel at half the speed of light，不是宾语从句，因为它不在动词后面。)6 ) Some scientists do not believe that the journey to Mars will be very comfortable.一Here 4that the journey to Mars will be very comfortable? is an object clause because its after the verb believe. So its O.(在这句中“hat the journey to Mars will be very comfortable是宾语从句，因为它在动词，believe，后面。)Step 4 The Object clauses introduced by if or whether(PPT)T: Now lets learn the Object clauses introduced by if or whether.T: Daniel has learned a lot about living on Mars.

I want to know if /whether you have finished your homework.T: Can you work out the rules yourselves?(PPT)Tips1 We can use if or whether to introduce an object clause when it expresses a yes /no question.(我们可以用，f或whether引导一般疑问句。)2 The word order in the object clause is just the same as that in the statement.(宾语从句应该用陈述语序。)T： Boys and girls , please look at some other exercisesput the two parts into the object clauses using if or whetherJ ?(PPT)Will transport on Mars be much better than on Earth?Are you certain?2 ) Is gravity a problem for the early settlers on Mars?Can you tell me?3 ) Does it take very long to travel from Earth to Mars?Do you know?4 ) Are many people going to move to Mars?Can you tell me?5 )Did the USA send a space robot onto Mars last year?Do you know?Keys:1 Are you certain if / whether transport on Mars will be much better than onEarth ?2 Can youtell me if / whether gravity is a problem for the early settlers on Mars3 Do youknow if / whether it takes very long to travel from Earth to Mars4 Can youtell me if / whether many people are going to move to Mars5 Do you know if / whether the USA sent a space robot onto Mars last yearT: Now weve learned about the object clauses introduced by that and the object clauses introduced by if or 4whether9.
