China Daily May16,2021 Hot News China’s Zhurong Rover Lands on Mars
The Zhurong rover was transported on a long journey to Mars by the Tianwen-1 spacecraft which began orbiting the red planet in February. The rover touched down on the surface of the planet before midnight on May 15, 2021. It is an important event for China, as only the U. S. A. had ever managed to land something on our neighboring planet before Zhurong. Some other countries have also tried before, but their rovers have either crashed or lost contact. After landing, Chinese President Xi Jinping congratulated the mission team on its “outstanding achievement.” Less than a week after its landing, Zhurong returned its first two pictures. One is a black-and-white photo taken through a fisheye lens showing a view of where it landed. The other is in color, showing view of the rovers’ solar panels (太阳能电池板). If things go as planned, Zhurong will spend about three months studying the local environment around it and looking for signs of water ice on the Martian surface. |

26、If the only sports you do are dancing your fingers across your keyboard, you could be in serious danger of more than just becoming overweight and out of shape.
Do you often feel sleepy, like something is weighing down on your head? Do you feel forgetful? Do you sometimes feel uncomfortable up and down your neck and lower back, and you can’t explain why? Do you get sick often? It could be radiation (辐射) from your computer causing it. If you spend three hours or more a day in front of a computer (and at this point, who doesn’t?), you are more easily harmed by the hazards.
We have got so used to using computers that we often neglect (忽视) to think of them as dangerous sources of harmful radiation. A safe amount of radiation is 25 V/m (Volts/meter). Do you want to guess how much our personal computers give off?
Keyboard: 1000 V/m
Mouse: 450 V/m

CPU: 170V/m
Notebook computers: 2,500 V/m
Ways of Protect Yourself from Harmful Computer Radiation
1. Decorate your desk with cactus (仙人掌) plants, they take in radiation.
2. Drink two to three cups of green tea a day and eat an orange daily. The vitamins in tea leaves and oranges protect us from radiation and keep our eyes healthy as well.
3. Use a screen filter（滤色镜） for your monitor.
4. Avoid having metal objects (金属物体) nearby on your desk.
5. Put the back of the computer to the wall. Most of the radiation comes off the back.
