The money people receive as personal income may be either spent or saved. However, not all spending is completely voluntary. A significant portion of our income goes to pay personal taxes. Most workers never receive the money they pay in personal taxes, because it is withheld from their paychecks. The money that individuals are left with after they have met their tax obligations is disposable personal income. Disposable income can be divided between personal consumption expenditures and personal savings. It is important to remember that personal saving is what is left after spending.

A. money earned.
B. not money earned but money received.
C. money received because you have contributed to the economy.
D. money earned because you have furnished a service to the economy.
5. The passage implies that
A. people willingly pay taxes because they want to do something useful to the country.
B. people willingly pay taxes because they do not want to be looked down upon by others.
C. people pay taxes unwillingly because they feel they will be arrested if they do not.
D. people pay taxes somewhat unwillingly.
The Gene Industry
Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls “metal-hungry microbes that might be used to mine valuable trace metals from ocean water.” They have already demanded and won the right to patent new life forms.
Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of “microbe spills” that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.
Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us? Should we attempt to eliminate “inferior” people and breed a “super-race” ? （Hitler tried this, but without the genetic weaponry that may soon issue from our laboratories. ）Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate “unfit” babies? Should we grow reserve organs for ourselves, each of us having, as it were, a “savings bank” full of spare kidney, livers, or hands?
Wild as these notions may sound, every one has its advocates（and opposes） in the scientific community as well as its striking commercial application. As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God? “Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines, automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created. ”
