    　　About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels(控制板)on the ground rather than the roof．Then they began to develop the Solar Roadway．The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun．while providing safer driving conditions, along with power and data delivery．They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being used to build and resurface current roads can be used to build the Solar Roadways．

    　　Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor(微处理器)that monitors and controls the panel, while communicating with neighboring panels and the vehicles travelling overhead．The inventors suggest that this provides a communications device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems．The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions(抓地力)they need．

    　　According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots．

    　　The inventors say their Solar Roadway has many functions and advantages from main roads to driveways, parking lots, bike paths, sidewalks and runways．The Federal Highway Administration has given Brusaw ＄100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring．

    阅读理解

    　　When you donate blood, a small amount is usually taken in advance to test your blood type．If you are O＋, the O is your ABO type and the＋is your Rh type．It is possible to be A,B,AB, or O as well as Rh＋or Rh-．

    　　The ABO system was discovered by Karl Landsteiner in the early 1900s．He was awarded the Nobel Prize for his achievements．There are four basic types of　blood in the ABO system：A,B,AB and O．Everybody is born with one of these four types of blood．We get blood type, just like hair color and height from parents．Because of the substances(物质)contained in each type, the four groups must be transfused carefully．If two different blood types are mixed together, it may put a person into an extremely dangerous situation．Basically, A and B cannot be mixed．A and B cannot receive AB, but AB may receive A or B．In an emergency, type O blood can be given because it is most likely to be accepted by all blood types，so it is often called the universal donor．However，there is still a risk．For the opposite reason，AB is sometimes called the universal receiver．However，because there can be so many reactions in transfusions，patients usually receive only salt until their blood can be matched as exactly as possible in the blood bank of the hospital．

    　　There is a relationship between your blood type and your nationality．Among the Europeans, about 45 percent have type O while 42 percent have type A．The rarest is type AB．Other races have different percentage．For example, some American Indian groups have nearly 100 percent type out of 100 donors in the world．

    (1)

    Which of the following shown the correct relationships in blood transfusions?

    [　　]

    C．

    D．

    (2)

    The underlined word “transfuse” most probably means ________．

    [　　]

    to put the blood into a container

    B．

    to move the blood from one place to another

    C．

    to put the blood of one person into the body of another

    D．

    to give power to another person

    (3)

    The text mainly tells us ________．

    [　　]

    A．

    about the basic types of human blood

    B．

    what kind of blood is the most common

    C．

    about Karl Landsteiner who won the Nobel Prize

    D．

    the relationship between blood type and nationality
