根据对话内容,从对话后的选项中选出能填入空白处的最佳选项。(共5小题,每小题1分,满分5分。)并在答题卡上将该项涂黑。选项中有两项为多余选项。

---Eric,let’s go and see Jenny after school. I’ll take today’s math test papers to her.

---Good. We can see how well she is getting on and tell her all the answers to the exercises.

----I don’t think we need to tell her all the answers. She won’t be impressed.

----____61_______

---Well, she always likes dealing with math problems by herself.

---Is that so? __62___

---Don’t worry about that. I’m sure that she can work them out.____63____

---Well, that’s true, but have you thought about her absence from school all week because of her illness?

---Yes, I have.___64__

---She is always doing math exercises every time. What’s more, she often asks us what we are studying at school.

----  ___65____.

So I am confident that she can do quite well without our help.

What makes you think so?

If I were you, I would tell her the answers.

After all, she is a very clever girl.

I agree that she is able to solve the problems, but she missed school.

But do you remember what she is doing every time we see her?

What if she has some difficulty doing these exercises?
