OF ANIMALS PREPARE FOR THE COLD WEATHER? 
3.LISTEN AGAIN TO PART OF THE LECTURE. THEN ANSWER THE QUESTION. 
 (Student 2) 
Yes, I do. Does the groundhog have a good record, you know, about 
predicting whether winter’s over? 
(Professor) 
(laughs) It’s just a folktale, and I think you won’t be surprised that the 
groundhog isn’t … um … batting much more than fifty-fifty. 
WHAT DOES THE PROFESSOR MEAN WHEN HE SAYS THIS?

4. LISTEN AGAIN TO PART OF THE LECTURE. THEN ANSWER THE QUESTION. 
 (Student 3) 
Well, professor, I’m not … uh … exactly sure what … um … hibernation 
is. I mean … how is hibernation different from sleep? 
(Professor) 
Ah, … that’s a good question, Tom, one that I’m a little late in clarifying. 
WHY DOES THE PROFESSOR SAY THIS: 
 (Professor) 
Ah, … that’s a good question, Tom, one that I’m a little late in clarifying. 
5. LISTEN AGAIN TO PART OF THE LECTURE. THEN ANSWER THE QUESTION. 
 (Professor) 
But, it’s far from settled as to whether animals hibernate as an adaption 
to cold or as a reaction to a scarcity of food. Lowering body temperature 
and uh not moving is a way of saving energy that can’t be easily 
replenished during winter months. Now in my opinion, it would seem 
easier to resist cold per se than survive a lack of food … um, food 
needed to generate energy and warmth.
