When we donate blood, a small amount is usually taken in advance for at least ABO and Ph systems typing. 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 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 O out of 100 
donors in the world…
| 84 donors are Rh+ |
16 donors are Rh- |
| 38 are O+ |
7 are O- |
| 34 are A+ |
6 are A- |
| 9 are B+ |
2 are B- |
| 3 are AB+ |
1 is AB- |

Memory， they say， is a matter of practice and exercise. If you have the wish and really make a conscious （有意识的） effort， then you can quite easily improve your ability to remember things. But even if you are successful， there are times when your memory seems to play tricks on you.
Sometimes you remember things that really did not happen. One morning last week， for example， I got up and found that I had left the front door unlocked all night， yet I clearly remembered locking it carefully the night before.
Memory “tricks” work the other way as well. Once in a while you remember not doing something and then find out that you did. One day last month， for example，I was sitting in a barbershop（理发店） waiting for my turn to get a haircut， and suddenly I realized that I had got a haircut two days before at the barbershop across the street from my office.
We always seem to find something funny and interesting in incidents（事件） caused by people’s forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years. Unfortunately， however， absent-mindedness is not always funny. There are times when “tricks” of our memory can cause us great trouble.If you want to have a good memory， _____.
| A．you should ask someone else to help you to remember things |
| B．you should make a conscious effort to practice and exercise |
| C．you should never stop learning |
| D．you should try hard to remember things |
In the passage， the writer seems to tell us _____.
| A．forgetting things is serious and dangerous |
| B．always forgetting things is understandable |
| C．forgetting things at times is natural |
| D．the ways to protect yourself from memory “tricks” |
The best title for this passage is“_____”.
| A．How to Get a Good Memory |
| B．Tricks’ of Memory |
| C．The Danger of Forgetfulness and Absent-mindedness |
| D．Get Rid of Absent-mindedness |
As far back as 700 B. C, man has talked about children being cared for by wolves. Romulus and Remus, the legendary（传说的）twin founders of Rome, were said to have been cared for by wolves. It is believed that when a she-wolf loses her litter, she tries to get human child to take its place. This seemingly foolish and unreasonable idea did not become believable until the late nineteenth century when a French doctor actually found a ten-year-old boy having nothing on wandering in the woods. He didn’t walk upright, could not speak understandably, nor could he relate to people. He only growled（嗥叫）and stared at them. Finally the doctor won the boy’s confidence and began to work with him. After many long years of devoted and patient teaching, the doctor was able to get the boy to clothe and feed himself, recognize and say a number of words, as well as write letters and form words.The French doctor found the boy ________.
A. wandering in the woods B at his doorstep

In many societies, there is often greater acceptance of light skin than dark skin. Light skin may be seen as a mark of beauty, intelligence and success. These beliefs can lead to social pressure even within the same racial or ethnic group, if some members are darker skinned than others.
The result is that skin lightening has become a common activity across Africa, Asia and other areas of the world. More and more people with dark skin are using skin-lightening products, even if they may face health risks.
They believe that having whiter skin will improve their lives. Many people think they will have a better chance of getting a job or marrying into a better family. Or they want to look like what their society generally considers beautiful.
Some beauty care products and soaps contain chemicals that make skin lighter. This process is also called bleaching. But some of the chemicals are extremely dangerous. One of the chemicals has been linked to kidney (肾) damage and some kinds of cancer. It also causes low birth weight in babies when mothers use it during pregnancy.
At first, bleaching products make the skin color lighter. But after long-term use they can cause problems. They can even make some skin darker. The chemicals in the products block and break down the natural process that gives color to skin. The skin loses its natural barrier to protec
t against sunlight. Then the skin can become thick and discolored. Usually the person will use more of the product in an effort to correct the problem, but this only makes it worse.
Fatimata Ly treats skin cond
itions in the Senegalese capital，Dakar. Doctor Ly says skin bleaching has become a problem throughout Senegal. She says the chemicals are now more dangerous because they are stronger. Some cases have resulted in blackened fingernails, infections and permanent skin damage.
And these are not the only risks. Experts say some people who change their skin color suffer emotional da
mage. They feel regret and sadness. They feel that instead of risking their health, they should have learned to love and accept their skin color as it was. Which of the following words can replac
e the underlined word “bleaching”?
| A．whitening | B．changing | C．lighting | D．pleasing |
Why has the skin lightening become a common activity all over the world?
| A．There are many products that can make the dark skin light. |
| B．Many people with dark skin have no confidence. |
| C．Relatively speaking, light skin has more advantages over dark skin. |
| D．People with dark skin are forced by the pressure of their families. |
According to the text the following are the risks using the bleaching products EXCEPT________.
| A．blackened fingernails | B．permanent skin damage |
| C．emotional damage | D．a waste of time and money |
From the text we can conclude the writer’s attitude toward using the bleaching products is probably ________.
| A．supportive | B．positive | C．doubtful | D．negative |
When something goes wrong，it can be very satisfying to say, “Well, it’s so-and-so’s fault.” or “I know I’m late，but it’s not my fault; the car broke down.” It is probably not your fault，but once you form the habit of blaming somebody or something else for a bad situation，you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.
Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague (同事) causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job
well.
This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to dev
elop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stones for success.According to the passage, winners .
| A．deal with problems rather than blame others |
B．meet with fewer difficulties in their liv es |
| C．have responsible and able colleagues |
| D．blame themselves rather than others |
The underlined word remedy in Paragraph 1 is closest in meaning to .
| A．avoid | B． accept | C．improve | D．consider |
When your colleague brings about a problem, you should .
| A．find a better way to handle the problem |
| B．blame him for his lack of responsibility |
| C．tell him to find the cause of the problem |
| D．ask a more able colleague for help |
Which of the following is the best title for the passage?
| A．A Winner’s Opportunity. | B．A Winner’s Secret. |
| C．A Winner’s Problem. | D．A Winner’s Achievement. |
