阅读下面的文字,完成小题。

鱼,我所欲也;熊掌,亦我所欲也,二者不可得兼,舍鱼而取熊掌者也。生,亦我所欲也;义,亦我所欲也,二者不可得兼,舍生而取义者也。生亦我所欲,所欲有甚于生者,故不为苟得也;死亦我所恶,所恶有甚于死者,故患有所不辟也。如使人之所欲莫甚于生,则凡可以得生者,何不用也?使人之所恶莫甚于死者,则凡可以辟患者,何不为也?由是则生而有不用也,由是则可以辟患而有不为也。是故所欲有甚于生者,所恶有甚于死者,非独贤者有是心也,人皆有之,贤者能勿丧耳。   

一箪食,一豆羹,得之则生,弗得则死。呼尔而与之,行道之人弗受;蹴尔而与之,乞人不屑也。   

万钟则不辩礼义而受之。万钟于我何加焉?为宫室之美、妻妾之奉、所识穷乏者得我与?乡为身死而不受,今为宫室之美为之;乡为身死而不受,今为妻妾之奉为之;向为身死而不受,今为所识穷乏者得我而为之,是亦不可以已乎?此之谓失其本心。

Large companies need a way to reach the savings of the public at large. The same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. There can be little hope of raising the money needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money, for long-term projects. So companies turn to the public’ inviting people to lend them money, or take a share in the business in exchange for a share in future interests. This they do by issuing stocks and shares in the business through the Stock Exchange. By doing so they can put into circulation the savings of single persons and institutions, both at home and abroad.

When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead he sells his shares through a stockbroker to some other Saver who is seeking to invest his money.

Many of the services needed both by industry and by each of us are provided by the government or by local organizations. Without hospitals, roads, electricity, telephones and railways, this country could not work. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than’ it is raised through taxes alone. The government, local organizations and nationalized industries therefore frequently need to borrow money to finance: major capital spending, and they, too, come to the Stock Exchange.

There is hardly a man or woman in this country whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another his new money must come from the savings of the country; The Stock Exchange exists to provide a channel through which these savings, can reach those who need finance.

The money which enables these companies to go ahead with their projects is().

A.exchanged for part ownership in the Stock Exchange

B.raised by the selling of shares in the companies

C.repaid to its original owners as soon as possible

D.invested in different companies in the Stock Exchange
