Old age is often accompanied by various kinds of illnesses. When he woke up on a July morning in 2001, Robert Tools, 59, could hardly lift his head off his pillow. He had suffered from heart troubles since a decade ago.(30)The 6-foot-3-inch former librarian and administer was too sick for a heart transplant. So he agreed to let two surgeons try something that had never been done before.(31)That afternoon Tools became the first person ever to be implanted with a self-contained artificial heart.(32)Eight days later, Tools left the hospital for the first time to take a stroll through a city park, with his artificial heart pumping blood through his body. The heart is powered by(31)a battery implant that holds a 30-to-40 minute charge. The battery is recharged via a coil attached to an external battery pack good for two hours, which Tools wears on a belt. Or the coil recharger can be plugged directly into a wall outlet.(31)A small controller, about the size of a palm, is also implanted in the chest to regulate blood flow. The tiny controller knows how to adjust to his body’s need for higher or lower blood flow when he stands, sits, walks, or otherwise.(32)But Tools’ mobility is still limited. Most of the time,(31)a transmitter implanted in his chest broadcasts data to a computer in his hospital room so that doctor can continually monitor and fine-tune the blood flow.(32)Tools says living with an artificial heart means adjusting to some strange new sensations. "The biggest thing is getting used to not having a heart beat, except a whirring sound, and that makes me realize that I’m alive because I can hear it without a stethoscope(听诊器)."
30. What do we learn about Robert Tools from the passage?
31. What kind of devices was implanted into Tools’s chest?
32. What’s the result of the treatment?

选项 A、An artificial heart, battery, a controller, and a transmitter.
B、An artificial heart, battery, wall outlet, and a transmitter.
C、An artificial heart, battery pack, wall outlet, and a transmitter.
D、An artificial heart, battery pack, a controller, and a transmitter.

答案A

解析 事实细节题。文中提到Robert Tools是第一个接受人工心脏移植的病人。文章接着指出随同人工心脏一同植入Tools胸腔的还有为人工心脏提供能量的电池、调节血液流动的控制器、监视心脏运行并为医生提供数据的传送器。由此可知,植入Tools胸腔的有人工心脏、电池、控制器以及传输器。
