Most millionaires measure success by net worth， not income. Instead of taking their money home， they plow as much as they can into their businesses， stock portfolios and other assets. Why? Because the government doesn‘t tax wealth; it taxes income you bring home for consumption， the more the government taxes.

　　The person who piles up net worth fastest tends to put every dollar he can into investments， not consumption. All the while， of course， he‘s reinvesting his earnings from investments and watching his net worth soar. That’s the attitude as well.

　　The best wealth-builders pay careful attention to their money and seek professional advice. Those who spend heavily on cars， boats and buses， I‘ve found， tend to skimp on investment advice. Those who skimp on the luxuries are usually more willing to pay top dollar for good legal and financial advice.

　　The self-made rich develop clear goals for their money. They may wish to retire early， or they may want to leave an estate to their children. The goals vary， but two things are consistent： they have a dollar figure in mind-the amount they want to save by age 50， perhaps – and they work unceasingly toward that goal.

　　One thing may surprise you. If you make wealth – not just income – your goal， the luxury house you‘ve been dreaming about won’t seem so alluring. You‘ll have the attitude.

　　A.Wealth is judged according to the life style one has.

　　The promise of finding long-term technological solutions to the problem of world food shortages seems difficult to fulfill. Many innovations that were once heavily supported and publicized have since fallen by the wayside. The proposals themselves were technically feasible， but they proved to be economically unviable and to yield food products culturally unacceptable to their consumers.

　　One characteristic common to unsuccessful food innovations has been that， even with extensive government support， they often have not been technologically adapted or culturally acceptable to the people for whom they had been developed. A successful new technology， therefore， must fit the entire social cultural system in which it is to find a place. Security of crop yield， practicality of storage， and costs are much more significant than previously been realized by the advocates of new technologies.

　　The adoption of new food technologies depends on more than these technical and cultural considerations; economic factors and governmental policies also strongly influence the ultimate success of any innovation. Economists in the Anglo-American tradition have taken the lead in investigating the economics of technological innovation. Although they exaggerate in claiming that profitability is the key factor guiding technical change—they completely disregard the substantial effects of culture—they are correct in stressing the importance of profits. Most technological innovations in agriculture can be fully used only by large landowners and are only adopted if these profit-oriented business people believe that the innovation will increase their incomes. Thus， innovations that carry high rewards for big agribusiness groups will be adopted even if they harm segments of the population and reduce the availability of food in a country. Further， should a new technology promise to alter substantially the profits and losses associated with any production system， those with economic power will strive to maintain and improve their own positions. Therefore， although technical advances in food production and processing will perhaps be needed to ensure food availability， meeting food needs will depend much more on equalizing economic power among the various segments of the populations within the developing countries themselves.

　　C.normally occur only when the innovation favors large landowners.

　　D.generally cost the country more than will be earned by the innovation.

　　3.The first paragraph of the passage best supports which of the following statements?

　　A.Too much publicity can harm the chances for the success of a new food innovation.

　　B.Innovations that produce culturally acceptable crops will generally be successful.

　　C.A food-product innovation can be technically feasible and still not be economically viable.

　　D.It is difficult to decide whether a food-product innovation has actually been a success.
