根据短文理解，选择正确答案。

    Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood-powered or coal-powered stoves.

    One way to reduce the number of deaths is through cooking equipment powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the "Sol-4". "It is four square meters of mirrors, six to eight meters in length. It is quite a large cooker. "

    The "Sol-4" works by reflecting (反射) light from the sun off large mirrors. The mirrors direct (把……对准) the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.

    The cooker is also much "friendlier" than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals would be less likely to have breathing illnesses from harmful smoke.

    At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.

    Each cooker costs about $ 2,000, which is a large amount of money for most Africans. To solve that problem, Crosby Menzies has created a non-governmental organization called Solar Cookers for Africa.  It plans to raise money through donations to provide poor people with solar cooking equipment.

    Philip is a school boy. On his twelfth birthday, he decided to give up eating 1.

    "I don't think it's right to eat animals," he said. "They live on the Earth just like us and they are our friends." Philip's parents were not happy about that. "You are a growing boy," his mother said "You need meat. Don't you want to become healthier and 2?" His mother put some 3, rice and carrots in front of him. "I want you to eat all your food now," she said. "Don't 4 anything." Philip didn't want to make his mother sad. But he ate only the rice and the carrots without touching the beef.

     "You're a silly boy!" said his father 5. "I'm getting very angry with you."

     "I'm sorry, Mum and Dad," answered Philip. "I don't want you to be sad or angry. 6 I really don't want to eat any meat. "

     "Then have some fish, dear," said his mother.

     "Oh no, I can't!" cried Philip. "Fish are living things, too.

     "Well, you can't have 7 to eat at all if you don't eat any meat or fish," said his father.

    The next morning Philip got up hungry. His father walked to the 8 with him and asked to see the teacher. "Is this what you teach the students at school" he asked the teacher. "Philip 9 to eat meat at home. He doesn't listen to what I say. "

    "I don't agree with Philip," replied the teacher. "But I think he is 10 to do what he thinks is right. We teach the students to do that."
