最后一篇lecture最后一题
You are gonna do such a thing? Well, that first touch of ice apparently triggers a biological response inside the frog. That first of all starts drawing water away from the center of its body, so the middle part of the frog, its internal organs, its heart, lungs, liver, these start getting drier and drier while the water that’s being pulled away is forming a puddle around the organs just underneath the skin. And then that puddle of water starts to freeze. OK, up to known, the frog’s heart is still beating, right? Slower and slower but…and in those last few hours before it freezes, it distributes glucose, a blood sugar throughout its body, its circulatory system, sort of acts like an an antifreeze.
B: A solution of antifreeze like you put in your car in the winter?
A: Well, you tell me. In frogs, the extra glucose makes it harder for the winter inside the cells to freeze. So the cells stay just slightly wet, enough so that they can survive the winter. Then after that, the heart stops beating altogether. So is that the same?

34. What does the professor imply when she says this  
She wants the student to clarify his question.
She wants the student to draw his own conclusions.
She thinks the student does not understand how car antifreeze works
She thinks the student has misunderstood her point

答案是B，我选的是C，感觉是教授后来说的是正确的解释，好像是学生提出的观点并不正确，所以想不通。。
