Would you be able to go through a whole day without using a light bulb? Most people probably wouldn’t. Today, almost every building uses light bulbs as their main light source. Although we use them daily without much thought, light bulbs were once a costly and the newest technology. A lot of people’s hard work led to the light bulb’s invention, which has impacted our lives greatly.

The first light bulbs were glass containers that release light when an electric current heated a part inside called a filament (燈絲). Electric light bulbs are also known as incandescent (白熾) light bulbs. These days, we use energy-saving bulbs that are better for the environment. Nick Holonyak, Jr., an American engineer, invented the first light-emitting diode light (LED) in 1962. An LED light bulb uses one-third the electricity as an incandescent light and lasts far longer.

In 1802, a British scientist named Humphry Davy created the first electric light. Then, in 1835, other British scientists created the first constant stream of electric light, although the light didn’t shine very long. In the following decades, scientists experimented with light bulb filaments made of different types of materials, hoping to create a longer stream of electric light. In 1860, Joseph Swan found a material that produced a good light, but it burned out quickly. By this time, none of the light bulbs created were ready to be sold to the public for everyday use. Then, in 1878, Thomas Edison made more progress. He spent a lot of time researching what previous scientists had done. He and his team spent years experimenting with light bulb filaments. They eventually created the first light bulb that could release constant electric light for 1,200 hours. Edison immediately patented (取得專利) his light bulb design so that light bulbs could be produced and sold.

Light bulbs were safer and more convenient to use than oil lamps and candles. Increased use of light bulbs resulted in people being able to have a longer work day, so the average work day increased. Light bulbs also led to changes in building designs. Architects created windowless buildings, and lights could be placed in elevators and other new places.

【1】From Paragraph 1, we can learn that light bulbs were _______ in the past.

A. commonB. expensiveC. hardD. great

A. There was not enough money and engineering support.

B. There were no materials that could be used to save power.

C. Scientists from different countries couldn’t work together.

D. It was hard to find a filament material that shone long.

【4】According to the passage, which of the following statements in TRUE?

A. Light bulbs were as convenient as candles and oil lamps.

B. Edison made it possible to sell light bulbs to the public.

C. LED can save more power and make people’s work time longer.

D. Light bulbs make people stay in windowless rooms on work days.

【5】Which of the following would be the best title of the passage?

A. The invention we depend on.

C. The history of science and technology.

D. What changes building designs?

Like visible light, UV rays are energy waves released by the sun, only they cannot been seen. Some exposure (暴露) to those waves can do a body good. For example, ultraviolet B (UV-B) rays tell human skin to make vitamin D. Too much exposure can be harmful, though. Overexposure to UV rays can cause DNA problems, opening the door for skin cancer. Too much sun can also cause painful sunburns.

There are three different types of UV energy waves. They are UV-A, UV-B and UV-C rays. Each type moves at a different wavelength, with UV-A’s being the longest. Rays of UV-C are considered especially harmful to human beings. Fortunately, we have the ozone (臭氧) layer of the Earth’s atmosphere. It blocks out nearly all of the UV-C rays and most of the UV-B ones.

The moon doesn’t have much of an atmosphere, though. Back on the moon, things are more dangerous. Over the years, astronauts have planted six American flags on the moon. Some scientists think that powerful UV rays could have bleached all the colorful flags white by now. For this reason, the moon is a dangerous place to visit without protection.

You might think that astronauts who visit the moon would come home with terrible sunburns. That didn’t happen to Armstrong and his company. Neil Armstrong was a U.S. astronaut and the first person to walk on the moon. These astronauts all wore special spacesuits on their missions. Spacesuits were made with heavy fabrics that block out UV rays.

When Armstrong set foot on the lunar surface, he was wearing a see-through helmet (頭盔) with sun shades that were made of ultraviolet-stabilized polycarbonate. It is a very tough plastic that protects astronauts’ faces from UV rays. A weaker material could put the space travelers at risk for “snow blindness” and other problems. Conditions like these arise when UV rays damage parts of the human eyes.

Sunscreen (防曬霜) defends us from the UV rays that do pass through the ozone layer. However, there’s really no need for an astronaut to put on sunscreen. The risk of sunburn goes way down when astronauts are inside a spaceship. Inside the International Space Station (ISS), for example, there is no need for special suits. Astronauts regularly do their work in nothing but common cotton shirts and pants. To protect them from sunburns, the ISS uses UV-blocking windows. So do most space exploration ships.
