“I can't see clearly, because I don't wear my glasses today.” We always hear people saying something like this. Glasses are very important to many people. Do you know how they were invented and developed?
Glasses took a long time to develop into what you can find in the glasses store today. The Chinese first used colored glasses as fashion. They thought that those glasses had magic, but they didn't think that glasses could help eyes to see clearly.
In 1262, the inventor, Roger Bacon, discovered the amazing function(功能) of lenses(镜片), and he thought that glasses could be used to help people to see. Twenty years later, in Florence, Italy, the inventor, Alessandro di Spina, made the first pair of glasses that could help people to see.
Although these glasses worked, scientists didn't understand how glasses helped eyes to see. They thought that eyes sent out light onto whatever a person was looking at, and then the light came back to the eyes. Johannes Kepler finally found out how glasses worked.
Inventors continued to improve glasses. In 1784, Ben Franklin created glasses that had bifocal(双焦的) lenses. Many years later, in 1827, George Airy made circle-shaped glasses to correct astigmatism, an eye problem that stops the eyes from seeing things clearly.

If your answer "Yes" to more than two of these questions, you are one of those people with stress. So what can you do about it?
Doing relaxing exercises, talking with friends and listening to light music are all usual ways of relieving (减轻) stress. However, doctors now say that there are easier ways-people should laugh and smile more often. When you laugh and smile, your body relaxes. They also say that people, especially men, should X more often, because crying is a natural way of relieving stress.

Then, you should know the best skipping stone is flat, thin and small enough to hold in one hand. But now scientists say a heavier one, but no heavier than a tennis ball, is also good. That's because. . . When a heavier stone hits the water, a bigger part of it goes under the water so it gets a stronger push from the water. *Top tips: 1 Find the right stone. 2 Flat, calm water is best, like a lake or pool. 3 Turn the stone around quickly when you throw it. Don't throw hard. Instead, try to throw the stone quickly. 4 The best angle(角度) to skip the stone is 20 degrees. *The best way to hold a stone: Hold the stone between your thumb and middle finger. Put your pointer finger around the edge(边缘) of the stone. *The biggest number of skips of a stone on the water is 88. |
