After a long winter holiday, on April 20th, I returned to my school again. I was so excited to see my teachers and classmates. We didn¡¯t see each other for a long time. When I got to school at 7 o¡¯clock in the morning, teachers were waiting for us at the school gate. Before I entered the classroom, my teacher took my temperature. After I sat down, I found a Welcome card which my teacher prepared for me on the desk. I was moved deeply. At noon, my teacher put the lunch box on my desk. After school, it was teachers who disinfected the whole classroom. How great they are!

Thank you¡ªmy dear teachers. You have done a lot for us. We will try our best to study.

We promise that we can make progress. Please believe us.

¡¾ÌâÄ¿¡¿ The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit, look again. It may not be a cloud, but a Flogo ¡ª a 1ogo (±êÓï) that flies. It's a new form of advertising(¹ã¸æ) in the sky that's never been used before. It's a different way to market your products, logos, and events.

These funny logos are made with soap bubbles (·ÊÔíÅÝ) mixed with a little helium gas (º¤Æø) , which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $ 2,500 a day, can make a Flogo every 15¡ª25 seconds.

Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly to 20,000 feet, they usually float around at 300¡ª500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future.

Flogos are Green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment.

A.produce colorful cloudsB.advertise in the sky

¡¾ÌâÄ¿¡¿ Infrared thermometers£¨ºìÍâζȼƣ©, or temperature guns, have been widely used to detect£¨¼ì²â£©the early symptoms of COVID-19. They allow us to measure£¨²âÁ¿£©temperatures quickly. How do these thermometers work?

They determine temperature by measuring the energy coming from your skin £¨Æ¤·ô£©. Everything in nature has molecules £¨·Ö×Ó£© 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£¨ÎüÊÕ£©. The thermometers use a lens£¨¾µÍ·£©to focus infrared light from the skin onto a detector called a thermopile£¨Èȵç¶Ñ£©. 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 £¨¼ÆË㣩.

However, you might sometimes find that the results aren¡¯t always accurate £¨×¼È·µÄ£©. 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.

¡¾1¡¿Temperature guns, have been widely used to detect £¨¼ì²â£©the early symptoms of____________.

A.COVID-17.B.COVID-18.C.COVID-19.D.COVID-20.

¡¾2¡¿They determine temperature by measuring the energy coming from your____________.

A.skinB.headC.faceD.foot

¡¾3¡¿The electronic sensors inside the thermometers can measure the heat and read the____________ of the skin.

A.colorB.temperatureC.lightD.structure

¡¾4¡¿Which one of the following might not affect the accurate results?

A.The thermometers is too far from the body.

B.The thermometers is held for very long.

C.Make-up and sweat.

D.The thermometer is held steadily at the right time.
