Q: Which of the following is not true according to the conversation?
A: Their mother didn’t spend too much on buying flowers.
B: The mother used to have tough times with her mother-in-law.
C: The mother is positive and life-affirming.
D: The daughter feels very sad about her mother's past.
解析：D
难度级别：★★★。A正确，在原文中有“I didn't spend enough on flowers”,说明并没有花太多的钱在花上。B正确，从“grow up with someone who is critical of every single thing you say”推断。C正确，从“turned out to be the positive, life-affirming person”推断。D不正确，原文无法知道这个感情色彩。
======原文=====
Mrs. Geller: I didn't spend enough on flowers, and if I spent more she'd be saying 'Why are you wasting your money? I don't need flowers, I'm dead'.
Monica: That sounds like Nana.
Mrs. Geller: Do you know what it's like to grow up with someone who is critical of every single thing you say?
Monica: ...I can imagine.
Mrs. Geller: I'm telling you, it's a wonder your mother turned out to be the positive, life-affirming person that she is.
Monica: That is a wonder.
