1. (2017八下·黄冈期中) 根据短文内容的理解，选择正确答案。   

    Several weeks ago, more than 70 American students discussed with American First Lady Michelle Obama at the White House about health problems.

    The students asked lots of questions that day and Mrs. Obama answered them one by one patiently. Then Mrs. Obama explained the importance of making healthy choices(选择). The students were all eyes and ears as they listened.

    She told the students that she didn't always feel good about the choices her family was making. Some years ago, when she was working and living with her family in Chicago, Mrs. Obama realized she had to make changes in her family's lifestyle.

    "We were eating out too much, buying a lot of things, and drinking a lot of sugary drinks," she said. So Mrs. Obama started talking to her kids about eating healthily and exercising more. Soon they were cooking more, eating fewer desserts, and spending less time watching TV. Mrs. Obama realized that making little changes can have a big effect(效果)。

    Mrs. Obama said that young people should take care of their own health and their own futures. "Exercise isn't always about sports. It's just about moving," she said.
