     About 21,000 young people in 17 American states do not attend classes in school buildings.Instead,
they receive their elementary (初等) and high school education by working at home on computers.The
Center for Education Reform says the United States has 67 public "cyberschools", and that is about twice as many as two years ago.
     The money for students to attend a cyberschool comes from the governments of the states where they
live.Some educators say cyberschools receive money that should support traditional public schools.They
also say it is difficult to know if students are learning well.
     Other educators praise this new form of education for letting students work at their own speed.These
people say cyberschools help students who were unhappy or unsuccessful in traditional schools.They say
learning at home by computer ends long bus rides for children who live far from school.
     Whatever the judgment of cyberschools, they are getting more and more popular.For example, a new
cyberschool called Commonwealth Connections Academy will take in students this fall.It will serve
children in the state of Pennsylvania from ages five through thirteen.
     Children get free equipment for their online education.This includes a computer, a printer, books and
technical services.Parents and students talk with teachers by telephone or by sending emails through their
computers when necessary.
     Students at cyberschools usually do not know one another.But 56 such students who finished studies at Western Pennsylvania Cyber Charter School recently met for the first time.They were guests of honor at
their graduation.
1. What do we know from the text about students of a cyberschool?
A. They have to take long bus rides to school.
B. They study at home rather than in classrooms.
C. They receive money from traditional public schools.
D. They do well in traditional school programs.
2. What is a problem with cyberschools?
A. Their equipment costs a lot of money.
B. They get little support from the state government.
C. It is hard to know students' progress in learning.
D. The students find it hard to make friends.
3. Cyberschools are getting popular because ________.
A. they are less expensive for students
B. their students can work at their own speed
C. their graduates are more successful in society
D. they serve students in a wider age range
4. We can infer that the author of the text is ________.
A. unprejudiced in his description of cyberschools
B. excited about the future of cyberschools
C. doubtful about the quality of cyberschools
D. disappointed at the development of cyberschools

  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(物質(zhì))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)

C.

D.

(2)

[  ]

A.

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)

[  ]

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.

閱讀理解。
      Every year, World Blood Day is celebrated by blood services worldwide on 14 June, the birthday
of Nobel Prize winner Karl Landsteiner, the man who discovered the ABO blood group system. If you
have every thought of becoming a blood donor, just register to do it. And you should never worry about
the donation.
     Just under a pint (around 470ml) of blood is taken at one sitting. This amount is no more than 13
percent of your total blood volume, and is quickly replaced by your body.
     It may come as a surprise, but whole blood is only rarely used. Different blood components are used
to treat a range of conditions. None goes to waste. Red blood cells are frequently used to replace heavy
blood loss after an accident, surgery or childbirth. White blood cells and antibodies (抗體) are used to
help people fight infections if their immune system doesn't appear to be responding to antibiotics (抗生
素). Plasma (血漿), the straw-coloured fluid which carries the blood cells and contains proteins, are
used to treat burned patients.
     First-time donors should be aged between 17 and 65, weigh at least 50kg and be in good health. If
you have donated before, you can start being a donor again up to your 70th birthday.
     Although most people are able to give blood, some people who pose health risks or are at a higher
risk of having come into contact with an infectious disease are no tasked to be donors. Pregnant women
or those who have had a baby in the last 9 months should not donate blood.
     Blood has a very short shelf life. Some blood components can be kept longer than others, for instance
red blood cells will keep for 35 days but platelets(血小板)for only five. Remember, you should wait at
least 16 weeks before donating blood again.
1. People should never worry about the donation mainly because _____.
A. it causes no pain to their body
