Yet, people began to understand how electricity works only a little more than two centuries ago. Nature has apparently been experimenting in this field for million of years. Scientists are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.
All living cells send out tiny pulses of electricity. As the heart beats, it sends out pulses of record; they form an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain, too, sends our brain waves of electricity, which can be recorded in an electroencephalogram. The electric currents generated by most living cells are extremely small,often so small that sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all. When large numbers of these cells are linked together, the effects can be astonishing.
The electric eel is an amazing storage battery. It can send a jolt of as much as eight hundred volts of electricity through the water in which it lives. ( An electric house current is only one hundred and twenty volts, but two hundred and twenty volts in China.) As many as four-fifths of all the cells in the electric eel"s body are specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length of its body
56. Electricity was invented ______.
A. when man had no candles
B. about 200 years ago
C. to be operating computers.
D. by Thomse Edison
57. The following things can send out pulses of electricity except______.
A. electric eels and human hearts.
B. Electrical generators and animal muscle.
C. Stones and dry wood.
D. human brain and living cells.
58. The electric current send out by an eel can be
A. as much as 800 volts. B. about one hundred and twenty volts.
C. as high as the house current in China. D. stored in the water where it lives.
59. From this shot passage we can infer _____.
A. the shorter an eel is, the stronger electricity it produces.
B. we can always feel the electricity produced by living cells.
C. human beings get their knowledge about electricity from nature.
D. people learn about electricity from eels.

Just because you are in a wheelchair doesn’t mean you can’t enjoy the competitiveness(
竞争
) —the all-around fun —that playing sports offers you. More and more wheelchair users are playing sports every day —some even on a professional level. The following are just a few examples of the different choices you have.
Wheelchair basketball is a very common wheelchair sport. It was started over forty years ago as part of a medical recovery(
康复
) program. Over the years it has grown rapidly. Today wheelchair basketball is a professional sport that has more than 180 teams across the United States. In order to play wheelchair basketball, it is essential to have a lightweight wheelchair. Several different kinds of sports wheelchairs are on the market today just for sports fans.
Another wheelchair sport, quad rugby(
橄榄球
), was specifically designed for people who can’t move their arms or legs and are unable to play wheelchair basketball. It is a mixture of wheelchair basketball and ice hockey. To play the game you must have two teams of four players each.
Power soccer is another fun wheelchair sport that can be very fun and exciting. Players in power soccer must have an electric wheelchair. Two teams have two 30-minute halves to push the soccer ball over the other team’s goal line. The first team to reach the other team’s goal line most frequently wins.
Based on the sport you choose to take part in, there are several things you can buy for your wheelchair, including belts, gloves, bags for carrying things, drink holders and special back supports.

D.making people want to play sports
小题3:What is the main idea of the passage?

A lot of grown-ups worry that spending too much time playing video games isn’t good for a kid’s health. Now some doctors have noticed that kids who bring their hand-held game players to the hospital seem less worried about being there. These patients also seem to experience less pain when they are concentrating on a superhero adventure or a car race. At the Johns Hopkins Children’s Center in Maryland, young patients are finding hospital visits easier to deal with, thanks to a test program called the Hospital-based On-line Pediatric Environment (HOPE). Patients in HOPE have a life-threatening condition where their kidneys(
肾脏
)no longer filter(
过滤
)wastes from their blood. To get their blood cleaned, these kids must be hooked up to dialysis(
透析
) machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play online sports, racing, and adventure games with each other. Eventually they will be able to connect with kids in other hospitals who are suffering from the same problem. "We want to use the power of the Internet to bring together kids who feel that they are separated by their illness, and let them know that they are not alone," said Arun Mathews, the doctor who heads the program. He loves video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video game programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, who was struggling with cancer helped to design a video game where players get rid of cancer cells. That’s all great news, because doctors already know that reducing pain and worry helps patients heal faster.

Banks view online banking as a powerful “value-added” tool to attract and keep new customers while helping to eliminate costly paper handling or teller(出纳员)interactions in an increasingly competitive banking environment .Today , most large national banks , many local banks and credit unions offer some form of online banking , variously known as PC banking , home banking , electronic banking or Internet banking . Online banks are sometimes referred to as “brick-to-click” banks , both to tell them from “brick-to-mortar” banks that haven’t yet offered online banking , as well as from “virtual”(虚拟)banks that have no physical branches or tellers whatsoever .
The challenge(挑战)for the banking industry has been to design this new service channel in such a way that its customers will readily learn to use and trust it . Most of the large banks can now offer fully safe ,fully functional (功能的)online banking for free or for a small cost . As more banks succeed online and more customers use their sites , fully functional online banking will likely become as commonplace as automated teller machines (ATM).
Online banking has a lot of advantages . Unlike your corner bank , online banking sites never close; they’re at hand 24 hours a day , seven days a week , and they’re a mouse click away . If you’re out of state or even out of the country when a money problem appears , you can log on instantly to your online bank and take care of business . Online bank sites generally carry out and confirm (确认)deals at or quicker than ATM processing speeds . Many online banking sites now offer fashionable tools to help you manage all of your valuable items more effectively .
小题1:The word “eliminate” in the first paragraph probably means “ ”.
A.keep | B.remove | C.reduce | D.improve |
A.To make online banking attractive . | B.To open new services all over the world . |
C.To offer online banking for free . | D.To take care of business 24 hours a day . |
