必修三Unit 4 课下语篇提能练Ⅰ.阅读理解(2019·太原一模)More than 90 years has passed since Hollywood's official film organization first proposed plans to build its own museum. Those plans are finally becoming a reality, with the Academy Museum of Motion Pictures set to open in 2019.The project is underway at the site of a historic Los Angeles department store built in 1939. Museum officials say visitors will be able to “experience the magic of cinema” by learning about all parts of the filmmaking process.Film historian Kerry Brougher has been named director of the museum. Brougher says the museum will include over 12 million photographs and 80,000 screenplays as well as props (道具), costumes and other objects from famous films. The Academy Museum will also feature Oscar statuettes (小雕像) donated by actors who won the awards.Brougher says the museum is designed to make visitors feel like they are in a movie, too, with many interactive experiences.“You won't necessarily know what's coming next，”he adds.“You'll be in environments sometimes that make you feel like you've gone back to the past and that you're in the area that you're actually exploring.” He adds that visitors may even get the chance to walk down a red carpet and accept their own Academy Award.Currently, Hollywood only has a few possibilities for visitors. They can go along the Walk of Fame, visit movie studios or see the Dolby Theater, where the Oscars are presented. But beyond these, movie fans have limited possibilities.Eric Garcetti, the mayor of Los Angeles says the Academy Museum will provide visitors with the chance to experience many different parts of the film industry all in one place. Garcetti notes the museum will also serve the hundreds of thousands of local people working in film-related businesses. He says they, too, will finally be able to visit a place that celebrates their own Hollywood movie industry.语篇解读：本文主要介绍了好莱坞终于有了自己的电影博物馆，并将于2019年向公众开放。

Unit 4Astronomy: the science of the stars课时作业Ⅰ.阅读(2020·贵阳市普通高中高三年级摸底考试)Many of us think, wrongly, that the moon doesn't change. For example, the Tang Dynasty poet Zhang Ruoxu once wrote that “Generations have e and passed away; From year to year the mo ons look alike, old and new.”However, a new study published in the journal Nature Geoscience shows that the moon is in fact slowly shrinking over time. For the study, a group of US scientists examined and analyzed thousands of photographs taken by the NASA's Lunar Reconnaissance Orbiter Camera (月球勘测轨道飞行器照相机). They found that there were lots of faults (断层) on the surface of the moon. These faults were formed by recent movement on the moon.According to NASA, the moon is made up of pieces of rocks with a hot core. The moon continued to expand as it was born. But in this process, it released energy and cooled down. Then it began to shrink, in a way parable to the shrinking of a grape into a raisin. Over the past several hundred million years, it has bee 46 met ers “skinnier”. But due to its hard and rocky layer, the moon's surface continues to push up. “Some of these quakes can be fairly strong, around five on the Richter scale (里氏震级)，” said Thomas Watters, a senior scientist at the Smithsonian's National Air and Space Museum in the US.But does that mean the moon is a dangerous place that human shouldn't try to explore and live on in the future? Maybe not, reported The Telegraph.“This isn't anything to worry about. The moon may be shrinking, but not by much. It's not going anywhere，” Watters forted us.The new discovery proves that the idea that the moon is a dead, boring place is wrong. “We have been to the moon and we've done some great science, but there is still a lot we don't know. The moon is shrinking—we didn't really realize that until recently. It's a much more active and interesting place than we thought and we should explore that，” NASA scientist Nathan Williams said.篇章导读：本文是一篇说明文。
