[阅读选择]Parents often decide on the basis of what their children want. Cathy, a mother told us, “My children have packed lunches, because they say they hate school dinners. I make 3 packed lunches every morning, so our kitchen is like a sandwich bar in the morning.” However, another mother, Susan made her choice based on the nutritious value of the food. She said, “My daughter always has school dinners. I think she probably gets healthier food by having a cooked lunch at school than she would if I made a few sandwiches.”
Which of the following is TRUE according to the passage?
A、Katz thinks chips are good for his kids.
B、Susan‘s daughter likes eating sandwiches.
C、Cathy may have at least three children.
D、Jamie likes burgers and pizzas.
正确答案:C
答案解析:答案选C。细节查找并简单推断题。从本段,特别是I make 3 packed lunches every morning…可知Cathy有三个孩子在上学,有没有不上学的孩子不得而知,故选项C为最佳选项。其他三项均与原文意思不符。

C、The first message is the warning signal.

正确答案:B
答案解析:第一句讲的是疼痛的感觉是由两种信号signals 组成的,所以紧接着就提到两种信号的传播路线。B项恰恰照应了首句意思。
