2b 阅读理解
Jane, a reporter, is collecting information for the local newspaper. She is interested in the following things introduced in a magazine.
Smart Schoolbag
Forget to pack the books you need into your schoolbag in the morning rush?
A schoolboy aged 11 has invented a schoolbag. It tells you which books to pack. A small computer and a scanner(扫描装置) are fixed in the bag. As each book is put into the bag, it is checked by the scanner. If any book is missing, a message will be shown on the computer screen to remind you.
Weather Sweets
Can you eat weather?
A university makes that happen. It uses a 3D printer to create sweets based on the weather information of a certain day.
The shapes of the sweets are affected by wind speed. The colors of the sweets are decided by temperature. The sweets act as a weather record of the day when they are made.
Sunrise Bed
It’s hard for you to get up in the morning, isn’t it?
To help you get up, a company has created a “tool”—a sunrise bed.
It wakes you up gently as a sunrise does. Lights built into the bed turn on and start to get brighter and brighter. When the lights are fully on, soft music will begin to play. It will be louder and louder until you turn it off. The company explains, “The gentle light tells your body that it is morning, so it stops producing a chemical that helps you sleep.”

答案： 2b 1. D 2. B
3. C [解析] 细节排序题。根据“Sunrise Bed”下的信息“Lights built into the bed turn on and start to get brighter and brighter.”及“... soft music will begin to play. It will be louder and louder until you turn it off.”可知，日出床叫醒人的步骤是：灯先打开，然后灯光变得越来越亮，其次音乐打开，最后音乐的声音越来越大。故选C。
4. A [解析] 代词指代题。根据“Sunrise Bed”下的信息“The gentle light tells your body that it is morning, so it stops producing a chemical that helps you sleep.”可知，柔和的光线会告诉你的身体现在是早晨，所以身体会停止产生有助于睡眠的化学物质。能产生化学物质的是“你的身体”，故it指代“你的身体”。故选A。
5. C
