Every day new Inventions appear on the market. In recent years, a "talking pillow (枕头)"has been on sale in the UK. It has a speaker (扬声器) that can be connected to an MP3 player or a CD player. People can listen to music or radio programmes from their pillows when they sleep.
The pillow is popular with people who have a snoring (打呼噜的) partner. It can play music to cover the sound of the snoring. In a way, it is helpful for people to keep a good relationship.
The pillow is the most popular with students. Why? Because they prefer to listen to lessons before they sleep. They hope they will remember at least some of the information when they wake up.
A US study shows students who receive information during sleep can remember what they learn. But some teachers don't like the new idea. They think the traditional ways of learning may help students learn better.
