A

Have you ever wondered who invented the umbrella? The umbrella is one of the oldest and most useful inventions, yet its origins are unclear. We do know that it was first used in ancient Egypt, Assyria, and China over 4,000 years ago. In ancient times, umbrellas were not primarily for keeping dry; they were symbols of status and power. Kings and nobles used them to shield themselves from the sun.

The first waterproof umbrellas, however, appeared in China during the Zhou Dynasty. These early umbrellas were made of silk or oiled paper stretched over a bamboo frame. They were heavy and expensive, but they worked. The Chinese also developed a collapsible umbrella, which could be folded up when not in use—a design feature we still use today.

It wasn’t until the 16th century that umbrellas became popular in Europe. At first, people thought they were silly and unnecessary. Men, in particular, refused to carry them, considering them women’s accessories. However, a man named Jonas Hanway changed that. He carried an umbrella everywhere he went in London for 30 years, despite being mocked. Eventually, people realized how practical it was, and the umbrella became a common sight.

Today, the umbrella is an essential item worldwide. From blocking rain to providing shade, it serves many purposes. Its simple design—a canopy on a stick—has remained largely unchanged for centuries. The next time you open an umbrella, remember that you’re using a piece of technology that has been refined over thousands of years. It’s a great idea that truly stood the test of time.

26. What was the primary use of umbrellas in ancient times?

A. To keep dry in the rain. B. To shield from the sun.

C. To decorate homes. D. To signal for help.

27. What was a key feature of the Chinese umbrella during the Zhou Dynasty?

A. It was made of metal. B. It was collapsible.

C. It was very cheap. D. It was used only by soldiers.

28. Why did European men initially refuse to carry umbrellas?

A. They thought umbrellas were too heavy. B. They believed umbrellas were fragile.

C. They saw umbrellas as women’s items. D. They didn’t like the colors of umbrellas.

29. What can we infer about Jonas Hanway?

A. He was a fashion designer. B. He was a weather forecaster.
