It uses encryption to ensure that data is encrypted before transmission, making it much more difficult for hackers to intercept and read. HTTPS is commonly used for secure online transactions, such as submitting credit card information or personal details.四、编程题请编写一个Python程序，实现计算圆的面积和周长的功能。

But there have been times when snow has looked red, green, yellow, or black. There have been snowflakes of almost every color. Think how it wouldseem to have colored snowflakes coming down all around you.Black snow fell in France one year. Another year grey snow fell in Japan. It was found that the snow was mixed with ashes. This made it look dark. Red snow had come down in other countries. When this happened, the snow was mixed with red dust.Most snow looks white, but it is really the color of ice. Snow is ice that comes from snow cloud. Each snowflake begins with a small drop of frozen water. More water forms around this drop. The way the water freezes gives the snowflakes its shape.No two snowflakes are ever just the same size or shape. Sometimes the snowflakes are broken when they come down. Other snowflakes melt as they fall. All snowflakes are flat and have six sides, if they are not broken or melted. When the air is cold and dry, the falling snowflakes are small and hard. If the air wet and warm, the snowflakes are big and soft.Would you be surprised to see snowflakes as big as your head falling from the sky? It happened once in the United States.

At the time France was in a crisis. The government was badly run and people's lives were miserable. King Louis XIV tried to control the national parliament and raise more taxes. But his effort failed. He ordered his troops to Versailles. The people thought that Louis intended to put down the Revolution byforce. On July 14, 1789, they stormed and took the Bastille, where political prisoners were kept. Ever since that day, July 14 has been the French National Day. Louis tried to flee the country in 1792, to get support from Austria and Prussia. However, he was caught and put in prison. In September 1792, the monarchy was abolished. In the same year, Louis was executed. A few months later his wife, Marie, also had her head cut off. The Revolution of France had frightened the other kings of Europe. Armies from Austria and Prussia began to march against France. The French raised republican armies to defend the nation. The Revolution went through a period of terror. Thousands of people lost their lives.

In some kinds of work, one can solve the problem of speed if one pays by theamount of work to be done and not by the hour: work paid for in this__3__ is called piece-work. But it is not always possible to do this, so it is sometimes useful to pay workers at different rates, which take differences in skill into __4__. This usually means that the younger and therefore less experienced worker gets less than the __5__ and more experienced one, which seems reasonable enough.(1)、A：otherB：sightC：olderD：wayE：account答案：B(2)、A：otherB：sightC：olderD：wayE：account答案：A(3)、A：otherB：sightC：olderD：wayE：account答案：D(4)、A：otherB：sightC：olderD：wayE：account答案：E(5)、A：otherB：sightC：olderD：wayE：account答案： C五、英译汉(1)、All that glitters is not gold.(2)、I got married ten years ago.(3)、Excuse me.
