中文段落：

2015年，中国股市经历了一场惊心动魄的波动。那么，这场股市下跌究竟是从何时开始的呢？

回顾历史，2015年6月12日，被视为股市下跌的起点。这一天，上证指数达到了历史性的5178点，创下了七年来的新高。然而，随后市场风云突变，股市开始震荡下行。到了6月下旬，市场恐慌情绪蔓延，大量资金撤离股市，导致股市连续暴跌。短短几个月内，股市市值蒸发数万亿元，无数投资者遭受了巨大的损失。

这场股市下跌的原因是多方面的。一方面，当时市场上存在着严重的炒作和杠杆化交易，一旦市场出现波动，这些高杠杆资金就会迅速撤离，加剧了市场的下跌。另一方面，部分上市公司存在质量问题，业绩造假、违规操作等丑闻频发，严重损害了市场的信心。此外，国际市场的波动也对国内股市产生了影响。

股市下跌给投资者带来了沉重的打击，但也暴露出市场存在的深层次问题。对于投资者而言，应该保持理性，加强风险管理，避免盲目跟风。同时，政府也应该加强对市场的监管，打击违法违规行为，维护市场的公平和稳定。

英文段落：

In 2015, China's stock market experienced a thrilling ride of fluctuations. So, when did the stock market decline actually begin?

Looking back at history, June 12th, 2015, is considered the starting point of the stock market decline. On this day, the Shanghai Stock Exchange Composite Index reached a historic high of 5,178 points, marking a seven-year peak. However, shortly after, the market dynamics shifted, and the stock market began to decline in a volatile manner. By the end of June, panic spread throughout the market, and a significant amount of funds withdrew from the stock market, leading to continuous sharp falls. Within just a few months, the market capitalization evaporated by trillions of yuan, causing immense losses for countless investors.

The reasons for this stock market decline were multifaceted. On one hand, there was severe speculation and leveraged trading in the market. Once the market fluctuated, these high-leverage funds quickly withdrew, exacerbating the market's decline. On the other hand, some listed companies had quality issues, with frequent scandals of earnings falsification and illegal operations, severely damaging market confidence. Additionally, fluctuations in the international market also impacted the domestic stock market.

The stock market decline dealt a heavy blow to investors but also exposed the underlying issues within the market. For investors, it is crucial to maintain rationality, enhance risk management, and avoid blindly following trends. Simultaneously, the government should strengthen supervision over the market, combat illegal and违规 activities, and maintain market fairness and stability.
