8 （24分）观看电影和欣赏戏曲是人们闲暇时文化生活的重要内容。阅读材料，回答问题。材料一中国电影产业的发展在2013年尤其引人注目。截至9月底，全国电影票房收入达164.25亿元，同比增长34.86%，其中国产影片为95.58亿元，占比58.19%，同比增长93.79%。中国电影产业的崛起，在越来越好地满足人民群众的文化需求的同时，也越来越深入地影响着世界电影格局。材料二戏曲起源于民间，它保存着地方语言和世俗风情，是一个区域、一座城市的文化记忆，现在中国的大部分戏曲剧种都是世界级或国家级的非物质文化遗产，应该加强保护。目前，我国戏曲文化的发展虽有升温，但仍存困境：有些剧目一直沿袭传统的表演技法，形式刻板，缺乏吸引力；快节奏的生活和丰富绚丽的文娱活动使年轻人离传统的戏曲越来越远。（1）结合材料一，从文化与生活的知识角度，分析我国电影产业快速发展的意义。（8分）（2）结合材料二，运用文化生活的知识，说明加强对中国传统戏曲保护的原因。（8分）（3）根据材料二，运用文化生活的知识，分析我国戏曲如何实现创新。（8分）
9 D Earth is the third planet from the sun. It is one of the four inner planets. The other three inner planets are Mercury, Venus, and Mars. The inner planets are also called the rocky planets, because th ey are made of rocks. Earth is often called the “Water Planet”, because it is the only planet in our solar system which has liquid water on its surface. About 70% of the surface of Earth is covered by water! The other part of Earth is made up of continents and islands which have different landforms on them. Examples of landforms are mountains and plains. Plants and animals can live on Earth, because it has so much water. Earth spins very quickly compared to other planets. It only takes Earth 24 hours to spin around its axis one time. One Earth day is 24 hours long! Earth orbits the sun in 365 days! This makes one Earth year 365 days long! Earth is the only planet in our solar system where humans, other animals, and plants can live. There is plenty of water to drink or to live in. Water is present on Earth in its big oceans and in the air! Clouds are made of water vapor. The atmosphere has a lot of oxygen in it for animals to breathe, but the rest of our “air” is made up of water vapor, nitrogen, carbon dioxide, and other gases. The air is perfect for plants to grow. Earth temperature is not the same in all places, but the temperature is just right for plants, animals, and humans in most places on Earth. Like the other inner planets, Earth has volcanoes. Volcanoes on Earth are different from those on other planets, because they still erupt. Scientists think that there may be active volcanoes on other planets and moons in our solar system, but they are still studying this. Earth has one planet which we call the Moon. The surface of the Moon has many craters on it These were caused when meteorites hit it. It has many volcanoes on it which do not erupt anymore. We can see the moon at night without using a telescope. It is the closest space object to our planet ,Earth. 68.Earth is called the Water Planet,______. A. because animals need water B. the water makes it look blue from space C. it has liquid water on its surface D. Earth is the third planet from the sun 69. It takes Earth ______to orbit the sun in one year. A.24 hours B.24 days C.365 days D.360 days 70. Life exists on Earth,______. A. because the water, air, and temperature are just right B. there is water vapor in clouds C. Earth is the planet closest to the sun D. earth has volcanoes 71.The craters on the moon were caused by______. A. meteorites hitting its surface B. active volcanoes C. volcanoes which do not erupt anymore D. some reasons that are not mentioned
