B: I think reasons are complex, but in general, they do it to make money.B：我想原因很多，但是总的来说，都是为了赚钱。
A: But how do they make money in stock market?A：在股市上通过什么途径赚钱呢?
B: There are usually two ways. When they buy shares in a business, they have the ownership of the business, so if the company makes money, the company shares money with investors, which is called a dividend. A second way to make money is to sell the stock at a higher price than they paid when they bought it.B：通常有两种方法。当他们买进一家公司的股票，他们就是这家公司的部分所有者。当该公司赚钱了，它就与投资者分享利益，即股利。第二种方法就是，投资者以高出买入价的价格售出股票。
A: Why does a company want to share its money with others?A：为什么公司愿意与他人分享资金呢?
B: Because the company needs to raise money. First, when a company is doing well, it may need money to expand. By selling shares of stock, the company may get the money it needs. Sometimes, it is advantageous for the company to sell stocks for taxes reasons, because the tax law says the company may save money on taxes by selling shares on the stock exchange. However, sometimes a company sells shares of stock because it needs money to pay the banks.B：因为他们需要筹资。第一，公司经营情况良好时，它可能需要资金扩大业务，通过售出股票，公司能够得到所需资金。有时候，由于税收原因，发行股票对公司很有利。因为税法规定公司在证券交易售出的股票可以减免税收。但是有时候，公司售出股票是为了偿还银行贷款。
A: In this way, although there is no guarantee, both investors and companies would like to buy or sell shares of stock.A：所以在这种情况下，即使没有保障，投资者愿意买进股票，公司也愿意售出股票。
