нужна помощ! помогите указать из текста временные формы гл. to be и to have .

A partnership is an association of two or more persons to carry on a business for profit. When the owners of the partnership have unlimited liability they are called general partners. If partners have limited liability they are "limited partners". There may be a silent partner as well - a person who is known to the public as a member of the firm but without authority in management. The reverse of the silent partner is the secret partner - a person who takes part in management but who is not known to the public.
Any business may have the form of the partnership, for example, in such professional fields as medicine, law, accounting, insurance and stockbrokerage. Limited partnerships are a common form of ownership in real estate, oil prospecting, quarrying industries, etc.
Partnerships have more advantages than sole proprietorships if one needs a big capital or diversified management. Like sole proprietorship they are easy to form and often get tax benefits from the government.
Partnerships have certain disadvantages too. One is unlimited liability. It means that each partner is responsible for all debts and is legally responsible for the whole business. Another disadvantage is that partners may disagree with each other.
About 60 percent of the world’s population goes into business. Because of the rapid increase in world population, putting an amount of money into business will receive greater attention in future years.
