Having clean hands is important because people often use their hands to touch their eyes, noses and mouths. Touching these areas gives germs (细菌) the chance to go into the body.

“Washing hands is an important lifetime habit for staying healthy,” doctors say. Cleaning your hands is one of the best and also the easiest ways to protect yourself from getting sick. But it takes more than just placing your hands under running water for a few seconds.

How can you make sure you are washing your hands correctly? Here are five easy steps you can take to wash your hands.

● Wet your hands with warm water.

● Lather up with soap. Be sure to lather the backs of your hands, between your fingers, and under your nails.

Can you understand the following words? “Long time no see.” “Good good study, day day up.” “I like your smile, but unlike you put your shoes on my face.”

Yes, we call these examples Chinglish, like “people mountain, people sea”

Chinglish usually means English vocabulary with Chinese grammar on street signs or products.

However, many English speaking tourists love them. Tom has been living in Beijing for years. “I think many Chinese people dislike Chinglish. But I love it. It's quite interesting. I think if the translations of English in China are all perfect, something will be lost from Chinese culture.” However, Chinglish will probably become a part of history in future. Beijing has made a plan to correct Chinglish within(在…之内) five years. “It is so funny to see Chinglish on the signs. And they are a kind of trouble for communication between the Chinese and foreigners,” a Beijinger said.

Infrared thermometers(红外温度计), or temperature guns, have been widely used to detect(检测)the early symptoms of COVID-19. They allow us to measure(测量)temperatures quickly. How do these thermometers work?

They determine temperature by measuring the energy coming from your skin (皮肤). Everything in nature has molecules (分子) inside of it that are always moving around. This include our skin. The higher the temperature is, the faster the molecules move. The molecules give off infrared light while moving.

This kind of light can be focused or absorbed(吸收). The thermometers use a lens(镜头)to focus infrared light from the skin onto a detector called a thermopile(热电堆). The thermopile absorbs the infrared radiation and turns it into heat. The electronic sensors inside the thermometers can measure the heat and read the temperature of the skin after making some calculations (计算).

However, you might sometimes find that the results aren’t always accurate (准确的). It depend on how these devices are used. For example, how far away they are held from the body, how steadily they are held and for how long. Factors such as make-up and sweat will also affect the results.
