16．二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。

When Dr. Robert Metcalf first used a solar cooker, the future changed for millions of Africans. He knew that billions of poor people around the world depend on the use of wood for cooking. As they take more and more firewood from wild areas. They are destroying habitats around the world. Wood collection is one reason why many animals have become endangered.

“But sunshine can be an alternative to fire.” Dr. Metcalf says. Since his first solar cooked meal, he has helped people around the world to use simple new technologies to cook their food.

Each morning in villages across East Africa, small children and their mothers wake up and walk several miles to collect firewood to cook their food. It takes much of the day, and the heavy firewood they carry home on their heads lasts only a few days.

This is why Dr. Metcalf spends each summer in Africa. He teaches women and children in villages how to cook with the sun. So far, more than thirty thousand African families now have solar cookers, and new programs will introduce solar cookers to millions of families.

To find water, women and children may have to walk long distance to dig holes in dry riverbeds or to gather water from streams and shallow wells.

They fill their buckets（桶）and carry them home on their heads. The buckets often weigh as

much as forty pounds. Not only is finding water hard work, but the water is often polluted with

germs（细菌）that make people sick.

Dr. Metcalf and others developed a simple，reusable tool that people can use to make sure their water is safe to drink．The tool is calked a WAPI，which stands for “Water Pasteurization Indicator”. The pasteurization process is named after Louis Pasteur，who developed it in the 1800s.

17．二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确为“T”，错误为“F”。

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.

Of all the inventions that could benefit humankind, a reliable solar cooker remains one of the most necessary. Countless people across the developing world still cook their food by burning wood or even cow dung, causing breathing problems and severe pollution in some regions.

The searching for a practical solar cooker has gone on for decades and produced dozens of models. But none of them have caught on importantly for use in the developing world because they can’t store heat. Without the ability to store heat, a cooker cannot be used, for example, on cloudy days.

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.
