Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way to contribute to social work and help the community. It helps to save lives and helps those who are in need of blood due to bad condition or the heavy loss of blood during operations or in accidents.
You are able to give or donate blood every three or four month, and it is a great way to make a huge difference to someone’s life and you can always be proud of it after making valuable contributions to society. Blood donation is not a big problem, but you need to keep a few points in mind.
Before donating blood, make sure that the ferrum (铁) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. Afterwards, you will not feel faint or weak.
For required hemoglobin (血红蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.
For a good blood flow in your body, drink at least 6-7 glasses of water every day. Completely avoid a day before and after giving blood, taking alcohol (酒). Do not smoke half an hour before giving blood.
When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity, take a deep breath and try to calm yourself. Don’t join in some other activities.
When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.
Take a rest for 15 minutes after the donation. It helps you to feel relaxed.
Eat something and drink juice before leaving the blood donation centre. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Avoid some activities right away, for example, driving.
Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.

When we donate(捐献) blood, a small amount is usually taken in advance for at least ABO and Rh 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 least common 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.
1.Which of the following shown the correct relationships in blood transfusions?
2.The underlined word “transfuse” most probably means ________.
A. 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 writer suggests that the third most common blood type among the Europeans is ______.
A. B B. A C. AB D. O
4.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

Most people think about donating blood. However. Very few actuallv do it. Even the most consistent ones donate an average of just three to four times during their lifetime. Now the officials in Sweden are trying to change the trend with the help of modern-day technology.
The encouragement to donate again begins shortly after the donor leaves the clinic when he/she receives a "thank you" text. Though that certainly helps them feel appreciated, what is even more pleasing is the text they receive each time their blood is used to help someone in need.
Karolina Wiberg, manager of the Stockholm blood service, believes this small gesture not only results in repeat donors, but helps bring in new ones. The program that was started in Stockholm has received such positive feedback that it is now being rolled out across the country.
However, Swedish officials are not stopping there. They are also encouraging local clinics to publish the exact levels of the different blood groups they have at any given time on their websites. This allows potential donors to realize that their blood can make a difference in saving someone ' s life.
While all these outreach programs are great, busy citizens, even the ones with the best intentions have to be occasionally reminded. In order to jog their memories, officials ask people for authorization to send them text, Facebook, and e-mail reminders. Though that may sound disturbing, the citizens do not seem to mind, given that the messages are light-hearted and fun-things like "We won't give up until you bleed."
Though Sweden is currently the only country using modern technology to urge more donations, don't be surprised if more join in, especially if the Nordic (北欧) country's blood banks start to overflow!
1.Why is another text sent to blood donors after a "thank you" one?
A. To ask them for authorization.
B. To inform them their blood is used.
C. To remind them to donate blood immediately. '
D. To tell them the levels of blood groups.
2.What does "the program" in paragraph 3 refer to?
A, Publishing information about blood donation.
B. Giving Facebook reminders to citizens.
C. Sending text messages to blood donors.
D. Providing people with blood service.
3.What do people think of blood donation reminders?
A. Disturbing. B. Memorable.
C. Authentic. D. Acceptable.
4.What can we infer from the last paragraph?
A. Sweden will stop urging blood donation.
B. Sweden has benefited little from its program.
C. More countries may follow Sweden's example.
D. Nordic blood banks are in great need of blood.

Scientists may have found a way to reduce shortage of type O blood. Type O is the kind of blood that hospitals most often need. What the researchers are testing is an easier way to make type O blood out of other kinds of blood.
There are four main kinds of blood. Most people born with one of these four: Type A,Type B, Type AB or Type O. Type O can be safely given to anyone. So it is commonly used when a person is injured or sick and has to have blood.
The differences among blood types are linked to whether or not red blood cells contain certain kinds of sugar molecules(分子). These molecules are found on the surface of the cells.They are known as antigens (抗原). These antigens are found with type A, B and AB blood but not with type O.
More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of enzymes were required to make the change.
Doctor Henrik Clausen of the University of Copenhagen in Denmark led the study. The next step, he says, is to complete safety tests. The team is working with the American company ZymeQuest to test the new method. If it meets safety requirements(*k)and is not too costly,it could become a widely used life-saving tool to increase the supply of universal blood.
1.How do scientists deal with the problem of lacking type O blood?
A.Hope more people to donate type O blood.
B.Make the most of the present type O blood.
C.Develop new ways of using type O blood.
D.Make type O blood out of other kinds of blood.
2.What make people have different kinds of blood?
A.Sugar molecules in red blood cells.
B.People's different living conditions.
C.Peoples various immune systems.
D.The variety of peoples cells and genes.
3.What can we infer from the text?
A.Type O blood can be safely given to anyone
B.Antigens could easily be removed to create universal blood.
C.A Danish company wanted to involve itself in studying blood.
D.The new method is not safe enough to be put into use in hospitals now.
4.What is the best title for the text?
A.Four different kinds of blood
B.A new way to make type O blood
C.The latest research on blood type
D.Find the proper type of blood

Below is a selection from a popular science book.
If blood is red, why are veins (静脉) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker(超级油轮). But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed(腐烂)and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink(收缩)as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not.
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system(边缘系统). All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.
If exercise wears you out, how can it be good for you?
1.What is the color of blood in a vein near the surface of the skin?
A. Blue B. Light yellow
C. Red D. Dark reddish purple
2. Why do some old people look a little shrunken as they age?
A. Because their spine is in active use.
B. Because they are more easily affected by gravity.
C. Because they keep growing backwards.
D. Because their spine becomes more bent.
3.Which of the following statements about our brain is true?
A. In the long run, our brain probably works harder than our heart.
B. When our brain senses the spinning, we will feel dizzy.
C. The brains of the other mammals are as complex as those of humans.
D. Our feelings and emotions come from the most developed area in our brain.
4. What is the main purpose of the selection?
A. To give advice on how to stay healthy.
B. To provide information about our body.
C. To challenge new findings in medical research.
D. To report the latest discoveries in medical science.

If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.
