Police career is a profession that demands higher ethical standards than others. It is often said that police officers are like living in a transparent fish tank, being watched all the time. The majority of police officers are dedicated and hard-working, serving the people and doing the right things. All police officers have ideals: integrity and honesty, justice and courage. Yet, sometimes, we heard stories of bad cops doing bad things—bribery, misuse of force, abuse of authority, etc. These are the black sheep that hurt the entire profession and violate police code of ethics. Police officers should never permit personal feelings, prejudices, political beliefs, aspirations, animosities or friendships to influence their decisions. The following Law Enforcement Oath of Honor is recommended by the International Association of Chiefs of Police（IACP）as a symbolic statement of commitment to ethical behavior：

   On my honor, I will never betray my badge, my integrity, my character, or the public trust. I will always have the courage to hold myself and others accountable for our actions. I will always uphold my community and the agency I serve.

   The Oath of Honor’s brevity allows it to be constantly referred to and reinforced during conversations and ceremonies. It is strongly recommended by the IACP that all agencies adopt the Law Enforcement Oath of Honor.

       Five people were on an airplane, including a pilot, a president, a scientist, a priest, and an elementary student. When they were close to the destination, the pilot became very nervous because he found that the fuel was going to run out before landing. However, only four parachutes were left for them. There were only two options left for the passengers. They either had to jump out of the airplane or stay and wait for death. The pilot let the passengers make their decisions first because he thought it was his fault that the plane was out of gas.

      The president regarded himself as the most important person to his country, so he took a parachute and jumped out of the airplane. Then the scientist said that people also needed him, so he jumped with another parachute. Hence, only two parachutes were left. While the pilot and the priest were worried about what to do next, the elementary school student had a smile on his face. "Don’t worry," the student said, "Either the president or the scientist jumped out with my book bag, so we still have three parachutes left."

       Ponzi and pyramid schemes are both investment frauds. They both involve deceiving others by promising substantialincome or returns on an investor’s initial investment. Unlike a regular investment, these schemes can offer consistentprofits only as long as the number of investors continues to increase. Once the number tapers off, so does the money. Butthere are inherent differences between the two.

      The investment manager of a Ponzi scheme will promise you substantially higher returns than any traditionalinvestment with little to no risk. Investment strategies are often too complicated to understand and you may not receiveany financial documents. The “returns” actually come from the incoming funds contributed by later investors. Pyramid schemes similarly offer big returns for little investment capital. However, they require individuals to payan entrance fee and/or purchase products/services in order to participate. These people are then required to bring in morepeople to the scheme.

     People at the top are paid the most, receiving a portion of the money that the new recruits contribute.Those at the bottom of the pyramid make little to nothing, especially when no new individuals are recruited.

     Neuroscientists used an instrument called functional MRI to study the brains of two groups of bilingual people. One group consisted of those who had learned a second language as children. The other consisted of people who learned their second language later in life. When placed inside the MRI scanner, which allowed the researchers to see which parts of the brain were getting more blood and were thus more active, people from both groups were asked to think about what they had done the day before, first in one language and then the other.
    The researchers looked specifically at Broca’s area, in the left frontal part, which is believed to manage speech production. The two groups of people demonstrated different uses of their Broca’s area. People who learned a second language as children used the same region in Broca’s area for both languages. But those who learned a second language later in life made use of a distinct region in Broca’s area for their second language—near the one activated for their native tongue.
    Researchers concluded that when language is being hard-wired during development, the brain may
intertwine sounds and structures from all languages into the same area. But once that wiring is complete, the management of a new language, with new sounds and structures, must be taken over by a different part of the brain.

Most writers find it difficult to find a subject to write on. A method frequently used to gather ideas is brainstorming. The method has been used for many years in business. You get a group of people around a table, and they try to solve a problem. The people simply start talking and 9 to each other, then ideas come out in the process. Brainstorming is particularly valuable to the writer 10 it offers a technique for getting suggestions and leads for a subject. Most of us brainstorm 11 . You start with something—anything—and with a pencil and paper you talk to yourself. At first you write down whatever comes to mind. But after a few phrases appear, you gently apply pressure and shape some of the material as it 12 . Only when the ideas tend to get 13 should you come to a conclusion that may provide a subject. This may not be your final subject, but at least it is a beginning.
