国家开放大学作业答案

Millions of people around the world cook their food over a smoky fire every day. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers, or ovens, have been used for centuries. ?

Solar ovens consist of a system of reflectors and a cooking pot. The rest is up to your imagination! Once you have collected or bought your solar oven, you can use it to prepare hot meals in the backyard, at a campground or wherever your heart desires.

But now a group based at the?Norwegian University of Science and Technology?(NTNU) is reporting a?discovery?in solar cookers. They say it will lead to the production of practical solar cookers within a year and a half and it can store enough heat during a sunny day to work for an entire additional day, even if it is cloudy. ?渝粤搜题
