When a computer works on a group of programs, it can get very hot. Cooling the computer can cost a lot. So some scientists wonder what would happen if the heat from the computer could be used.
Large Internet companies (公司) such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems (系统). These systems send the heat into the air.
A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.
Boaz Leupe, head of the company, says that e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don’t have to pay to cool their computers.
Five homeowners in Holland are testing the heating system in their homes.
“We pay for the computer using, so, in that way, homeowners get heating for free,”Boaz says.
Jan Visser is one of the homeowners. “If you use the computer more, the e-Radiator producers more heat, ”he says, “It cannot provide enough heat if you don’t use your computer often.” But he is ready to try it. It’s a great help for his family.
The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.Before the e-Radiator appears, usually the heat of a computer ______.
| A．is sent into the air |
| B．helps the five homeowners |

| D．makes the computer work better |

| B．to help Microsoft |
| C．to heat the computer |

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.
A visit to a doctor’s office costs from 15 to 50 dollars. It’s so expensive. Many people in the United States think that doctors are overpaid. However, most doctors disagree. They say that they were asked to study medicine for a long time. Tuition for many years of medical education costs a lot of money. Doctors say that it is necessary for most medical students to borrow money from the bank to pay their tuition. Because their money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收费)people high prices for medical care.
Therefore the cost of medical care in America is high. Because high tuition is one cause of high costs, one way to lower costs would be to have medical school that are free or have low tuition.The underlined word "tuition" in the passage means “______”

Many years ago, when I was working as a volunteer at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease(疾病)and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a blood transfusion(输血)from her five-year-old brother.

The doctor talked to the little boy about what they planned to do, and asked him if he would like to give his blood to his sister. I saw him hesitate(迟疑) for a moment. Then he took a deep breath and said, "Yes, I’ll do it if it can save Lisa."
