One would have to be a fool to overlook the importance of using positive thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little w*w^w..c~o*mchemicals and good feelings which will reinforce the positive thoughts.

For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.

It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.

When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal (揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout (布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”
61. To find criminals, police usually _________.
A. check who are on the crime scene
B. seek help from local people
C. depend on new mathematical tools
D. focus on where crimes take place
62. O’Leary is writing a computer program that _________.
A. uses math to increase the speed of calculation
B. tells the identity of a criminal in a certain area
C. provides the crime records of a given city
D. shows changes in criminals’ patterns
63. By “I’m the only one who knows what gold looks like”, O’Leary means that he _________.
A. is better at finding gold than others
B. is the only one who uses math to make money
C. knows best how to use math to help solve crimes
D. has more knowledge of gold than other mathematicians
64. What do you know about O’Leary according to the passage?
A. He is a man full of impractical imagination.
B. He is a man full of self-confidence.
C. He is a man who is talkative but lazy.
D. He is a man who doesn’t like mathematics.
65. What is the main idea of the text?
A. Math could help police find criminals.
B. Criminals live near where crimes occur.
C. Crime records could be used to fight crime.
D. Computer software works in preventing crimes.

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…

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

  A B  A         B    A       B      A      B

 AB O   AB     O      AB     O     AB      O

      A             B            C               D

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  K^S*5U.C#O

  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

“I started going to clubs when I was nineteen. My friends went and they told me that I’d love it. They were right.” –Lara

Lara is a twenty-one-year old student who loves dancing. “At the moment, my favorite kind of music is acid jazz. I’d love to go to a Fatboy Slim or Ken Ishii gig. They’re so cool,” says Lara. Fatboy Slim and Ken Ishii are not pop stars—they are famous DJs. Being a DJ these days means more than playing records at a nightclub. DJs like Fatboy Slim have also produced a lot of successful CDs of their own music.

Nightclubs have been popular since the seventies but today’s clubs are different. They don’t usually open until at least 11 pm, and people often stay until 7 or 8 o’clock the next morning. Some clubbers will keep on dancing until 12 o’clock in the morning.

Why has dance music become so popular? Some people believe that clubs give young people what the hippies found in the sixties. They have somewhere to meet people just like them. Many clubbers say that dance music helps them to escape from their problems. They feel they are part of a big happy family. But most people just love to dance.
