Passage FourThe atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E. O. Wilson, a biologist at Harvard, calls the depletion(枯竭、耗尽)of rain forest areas "the greatest extinction since the end of the age of dinosaurs(恐龙)."Unlike some environmental issues, rain forests' depletion has fortunately received significant public and media's attention. Despite the opposition to the cutting down of rain forests, the problem continues. Every year, Brazil chops down an area of forests the size of the state of Nebraska. In addition to the Amazon's rain forests, many other forests are being cut down as well.: In Indonesia, Zaire, Papua-new Guinea, Malaysia, Burme, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain forests that were once great have been lost.According to some estimates, 50 million acres of rain forest are cut down every year. The United Nations says the figure is closer to 17 million acres. The World Wildlife Fund says that every minute,25 to 50 acres are cut down or burnt to the ground.The world's growing population has been a primary reason of rain forests' destruction. More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would alleviate the destruction of the rain forests.48. In the opinion of the author, ______are being destroyed terribly at present.A. the oceansB. the atmosphereC. the rain forestsD. all the above

The cause can be something as normally uneventful as driving over a bridge or flying in an airplane.And it can happen even if the person has driven over many bridges or flown many times before.A fast heart beat. Sweaty hands.Difficulty in breathing. A light一headed feeling. At first a person may have no idea what is wrong. But these can all be signs of what is known as panic disorder.

问答题Practice 3 Equity securities are known as shares (or stock) in a corporation. Stockholders are considered owners of the corporation. The Articles of Incorporation must state the number of shares and the characteristics of the stock. To issue stock is actually to offer shares of stock for sale. The corporation’s Board of Directors controls when and to whom the corporation’s shares are offered and sold. Outstanding shares—Outstanding shares are shares already issued and purchased by the shareholder or stockholder. Par value—Par value is an arbitrary value assigned to each share in the Articles of Incorporation but does not necessarily reflect the true market value of the stock. Shares may not be issued and sold by the corporation for less than their par value therefore it is sometimes advisable not to state any par value at all or state a par value lower than the estimated market price. No par value allows the Board of Directors to decide each time shares are issued what the price per share will be. In a very large corporation where the stock is publicly traded at a public exchange, such as the New York Stock Exchange, the public demand for the stock of the corporation rather than the Board of Directors determines the selling price of the stock. Capital account—The capital account of a corporation is an entry in the books of the corporation and is determined by multiplying the par or stated value of the corporation’s stock by the number of shares outstanding. For example, if the corporation had sold 1,000 shares of stock which had $10 par value, the capital account would be $10,000.
