6、ns.Predict by using pictures One way to get more out of your listening is to predict what you will hear.Using the pictures provided and the knowledge you already have,you can guess the kinds of information you should listen for.At times,you may even be able to guess exactly what will be talked about

7、.This will help you focus better when listening,making your listening more effective.(1)Listen to the conversation to check your prediction inActivity 2.Take down key words.1.Where are the people in the conversation going to go?2.What kind of place is it,and what does it focus on?3.What kinds of thi

8、ngs can you do there?Activity 3:Listening and speaking(1)Listen to the conversation to check your prediction inActivity 2.1.Where are the people in the conversation going to go?They are going to a science museum.2.What kind of place is it,and what does it focus on?It is a science museum that focuses

9、 on letting visitors experiencescience through interactive learning exhibitions.(1)Listen to the conversation to check your prediction inActivity 2.3.What kinds of things can you do there?You can probably try different activities to learn about sound,light,reflection,and so on.For example,you can go

10、 to a room with many mirrors facing eachother so it looks like there are many copies of you!Or you can playwith a big piano on the floor.(2)Write down the letters(A-E)for the photos in the orderthat you hear them.1 _ 2 _ 3 _4 _ 5 _ABCDE a hall of mirrors see myself reflectedthousands of timesDC a bl

17、the museum called Light Games.It was really cool.They had a hall of mirrors where I could see myself reflected thousands of times!Bill:A hall of mirrors can be a lot of fun.What else did they have?Judy:Well,they had an experiment where we looked at a blue screen for a while,and then suddenly we coul

18、d see tiny bright lights moving around on it.Youll never guess what those bright lights were!Bill:Come on,tell me!Judy:They were our own blood cells.For some reason,our eyes play tricks on us when we look at a blue screen,and we can see our own blood cells moving around like little lights!But there

19、was another thing I liked better.I stood in front of a white light,and it cast different shadows of me,in every colour of the rainbow!Bill:Oh,I wish I had been there.Tell me more!Judy:Well,they had another area for sound.They had a giant piano keyboard that you could use your feet to play.But then,i

20、nstead of playing the sounds of a piano,it played the voices of classical singers!Then they had a giant dish,and when you spoke into it,it reflected the sound back and made it louder.You could use it to speak in a whisper to someone 17 metres away.Bill:It all sounds so cool.I wish I could have gone

21、with you.Judy:I know,but we can go together this weekend.Id love to go there again!Bill:That sounds like a great idea!Activity 5:Talk about something more on the scientificmuseum.1.The conversation is about the City of Science and Industry,amuseum in Paris.Would you like to go to this museum?Whyor w

22、hy not?2.Are there any museums like this in China?What otherinteresting museums are there?1.The conversation is about the City of Science and Industry,amuseum in Paris.Would you like to go to this museum?Why orwhy not?Yes.The exhibitions seem really interesting.I think I would learn a lot there.2.Ar

23、e there any museums like this in China?What otherinteresting museums are there?Yes,there is,for example,the China Science and TechnologyMuseum in Beijing and the Shanghai Science and TechnologyMuseum.Activity 6:(1)Brainstorm a scientific research or experiment(Page 7,Activity 6&7).Example1.What scie

24、ntific phenomenon is the example about?2.Do you know the phenomenon?Where did you know it?3.What other scientific research/experiments have you everdone or read about?(1)Brainstorm a scientific research or experiment(Page 7,Activity 6&7).1.What scientific phenomenon is the example about?A non-Newton

25、ian fluid.2.Do you know the phenomenon?Where did you know it?Yes.In TV programs or books.3.What other scientific research/experiments have you everdone or read about?For example:the positive and negative charges of molecules.n.分子/微粒(2)Read the expressions to talk about scientific phenomena(Page 7),u

26、sing the following expressions Sample Presentation Today,I want to talk to you about the positive and negative charges of molecules.We can demonstrate how these interact through a simple experiment using milk,dish soap,and food colouring.First,cover the bottom of a shallow plate with milk.Now add tw

27、o or three drops of different liquid food colouring to the centre of the milk.They should form one large dark puddle in the middle of the milk.Now,dip a cotton swab into dish soap,and place it into the middle of the food colouring.You will see the colours quickly move to escape from the soap,making

28、interesting and beautiful patterns.This happens because the dish soap molecules have a strong negative charge,and the milk molecules have a strong positive charge.Like magnets,these molecules are attracted to each other,and so they appear to move around on the plate,taking the food colouring with them,making it look like the colours are quickly moving to escape from the soap.Constant dropping wears the stone.滴水穿石。
