T: Any different opinions?
T: Good! Class, you were required to prepare Activity 2 before class. It’s the tape-script of Part 1. Predict the right words from the context. Each group finds a capable candidate, and then writes your predictions on the blackboard.
Today’s topic is a big one--it’s dinosaurs, those strange (2)__________ which ruled the earth for no less than (3)______________, some of them were (4)_________, others were like the infamous（ 名声不好的）Tyrannosaurus Rex (霸王龙), carnivores who (5) ________meat and who (6)__________ the more peaceful plant eating dinosaurs.

(2 students write their answers on the blackboard.)
T: You’ve got creative answers! Boys and girls listen to Part 1 and then find out the right words from the tape-script.
T: Are you clear now? Let’s check them together. I’d like one student from each group to come up and correct the answers.
T: Here are the keys.
1) Mysteries of Nature
3) two hundred million years
4) plant eaters
5) lived off
8) 66 million years ago
(After correcting, Teacher checks any possible answers and scores them.)
T: Did the two perform a good job? Wonderful handwriting! I’m surprised! How can you figure out all the answers correctly! Well, Group A gets 5 points, Group B 8 points. Let’s give them a big hand, shall we? (Whole class clap!)
T: Well, from what we did just now, we obtain a listening Strategy. Who volunteers to translate it into Chinese?
Good listeners make predictions(做预测) using what they know about the topic to correct their listening comprehension, when the listening material is different from their prediction.
S8:（Slowly get the Chinese translation with Teacher’s help）
T: Good. Please keep in mind. It’s always helpful in listening. Let’s move to the next. Activity4: Match the words below with the pictures on the projector.

Ss: (All answer) 1, 2, 4, 5, 6!
T: Smart boys and girls! Both score 5 points. The following game is Hot. It is Super-quiz! Today’s topic is dinosaurs! The one who stands first gets a chance to answer. If you give a right answer, you get 3 points. If you don’t get it correctly, your members can help you. But if you fail, you lose 3 points. Ready? go!
S13: (Stands up first!) No4.
T: Good. Read the 2 questions and answer them.
S13: Theory Two: Dinosaurs were unable to adapt to the changes of climate.
Question1. What caused the changes in the climate?
S13: Perhaps the meteorite hit the earth and led to the disappearance of life. Finally it caused the changes of climate. People don’t know exactly what caused the changes.
T: Well-done! Go on.
S13: Question 2. Why couldn’t dinosaurs adapt to cold climate?
S13: The climate was cold. They had no furs to keep warm. Or they might have stopped evolving, and unable to adapt to changes in the climate.
T: Good. Any make-up?
S14: Dinosaurs were 冷血动物（cold-blooded animals）.They can’t survive the changes.
T: Thanks, clever boy! Now, Group A get another 6 points! Give them congratulations, shall we? (All clap) Next, ready?
S15: (Stands up first!) No, 2.
T: Oh! Read and answer.
S15: Theory 3: They killed each other.
Question1. Do you think dinosaurs were friendly?
S15: I think some were friendly. They lived off plants and lived in groups. They helped each other.
T: Anyone else has more?
S16: Maybe others had to kill and fight for a living.
Question 2.Why did dinosaurs kill each other?
S16: Maybe, they killed each other for food, space or mates.
T: Excellent! We can see you have a good knowledge in dinosaurs. Group B scores another 6 points. Let’s give them a big hand!
T: Now comes the last round of Super-quiz! One, two, start!
S17: (Quickly standing up) No1
T: Good! Let’s come to the questions.
S17: Theory 5 Cancer caused by radiation.
Question1How did dinosaurs get cancer?
S17: Due to the radiation coming from a dying star somewhere in our galaxy. The radiation was strong and bad. Slowly it caused cancer.
T: Good point! Next, please!
S17: Question 2. Do you think cancer could end the lives of all the dinosaurs? Why?
S17: Hard to say, but perhaps dinosaurs got cancer as time went by. They would die out in a long time.
S18: I think (It is) unlikely. If dinosaurs died of cancer, radiation might cause death to the others (as well).
T: Quite true! Of course, this is only a prediction! Let’s award the gifted students 8 points! (Whole class clap)
T: Last, we’ll have a discussion. Share your opinions with your partner, and then demonstrate in class. “Which theory do you think is the most likely, and why?” (3min)
Some related phrases and words:
the most widely accepted theory, meteorite, … hit the earth with such force that it create a huge dust cloud, extremely hot …,fire spread…, be destroyed…, stop the sunlight from getting through, …there be no light, no heat, and no food…, be unable to adapt to, climate change, disappear, extinct, stop evolving, survive, volcanic eruption, send out huge clouds of dust , cut off the light, more mammals(脯乳动物), seeds, nuts, steal eggs, give birth to male baby dinosaurs , because of freezing weather, no fur to keep warm, cancer caused by radiation from a star ,galaxy, fantastic（怪异的）, go for, for, can’t agree more…
T: (After discussion) Does Anyone want to share?
(The bell rings)
T: It’s a pity time is limited. I’d like you to organize your ideas into a short passage.
“Which theory do you think is the most likely, and why?”
Before you write, make sure what makes a good writing.
