It is called DSCOVR —the Deep Space Climate Observatory. It will replace a satellite that has been observing space weather. DSCOVR will begin its work during the worst of the 11-year-long solar cycle. This is a time when extreme weather on the sun can have the greatest effect on planet Earth. DSCOVR will gather information about a continuing flow of particles（粒子流）from the sun. We are protected from these particles by the Earth's magnetic field （磁场）and atmosphere. But we are not fully protected from what scientists call Coronal Mass Ejections（“日冕物质抛射”）. These are strong storms that can happen on the sun's surface. Thomas Berger is the director of the Space Weather Prediction Center at the National Oceanic and Atmospheric Administration, or NOAA. He says these ejections are much more dangerous than solar particles. He says the Coronal Mass Ejections are extremely large magnetic clouds that are expelled from the sun at extremely high speeds. He says when they affect Earth, it is like a hurricane affecting Earth in terms of space weather.

阅读理解：My school appeared on the news 进入查看：2022-2023学年英语周报九年级第25期答案及试题 My school appeared on the news last week because we had made an important change in our local area. Our class had planted a large garden in what was once only a vacant lot. It was a lot of work but it was all worth it. I got blisters (水泡) from digging, and we all got insect bites, too. I learned a lot about gardening and collaboration (合作), and then I learned about the media. Our teacher telephoned the TV station and informed them, of what we' had accomplished. She spoke with the producer. The producer checked with the directors, but they said there were plenty of stories similar to ours. They wanted to know what was special about our particular garden, since many schools plant them. The teacher explained that, after going on the Internet to learn about the prairie (大草原), we had made a prairie garden. We had gone to a prairie and gotten seeds from the plants, and then we planted them, We did not water the garden, but we did weed it. We decided to let nature water it with rain, since that was how prairies grew in the past. We sent a picture of the garden to the news station. In the picture, the grass was so high that it stood taller than the fourth grade students.
