19、在中国学习的梦想的事情。5解析：细节理解题。根据第一段“Chineselanguage teacher Xie Fang is excited that one of her former students from Indonesia has been admitted to Beijing Language and Culture University.”可知中文老师谢芳很高兴她的一名印尼学生被北京语言大学录取了。由文章可知，Alvin Rizqi Adrian已获准在中国学习，让语文老师谢芳高兴。故选D。答案：D6解析：词义猜测题。根据后文“the content of the text
20、books to make it easier and more interesting for the Indonesian children to learn Chinese.”可知，使印尼孩子学习汉语更容易，更有趣。所以应是谢芳改进了教科书。根据上下文语境可知画线单词意思为“改进”。故选B。答案：B7解析：推理判断题。根据倒数第二段中“At that time，he was a middle school student.He was so interested in Chinese that he worked very hard to learn and practice.”(那时，
21、他还是一名中学生。他对中文非常感兴趣，所以他非常努力地学习和练习)由此可推知，Adrian很特别，因为他很勤奋。故选C。答案：C8解析：主旨大意题。本文主要说明了一位中文老师谢芳教授印尼孩子学习中文，并帮助一名印尼学生实现了他在中国学习梦想的事情。故A选项“中文老师帮助印尼人实现梦想”符合文章标题，故选A。答案：AC(2020深圳高三统一测试)Rivers are the veins of the Earth，transporting the water and nutrients (营养物) needed to support the planets ecosystems，including
22、 human life.While many nutrients are essential to the survival of life，there is one element transported by water in rivers that holds the key to life and to the future of our planetcarbon. Carbon is everywhere and understanding the way it moves and is either released or stored by the Earth system is
23、 a complex science in itself.Carbon starts its journey downstream when natural acid rain，which contains carbon dioxide from the atmosphere，melts minerals in rocks.This helps transform carbon dioxide to bicarbonate (碳酸氢盐) in the water that then flows in our rivers.This is a very long process，which is
24、 one of the main ways carbon dioxide is removed from the atmosphere.Carbon is transported by rivers to oceans and once that carbon reaches the ocean，it is stored naturally in deep sea sediments (沉淀物) for millions of years.As carbon travels down a river，different processes may impact whether it conti
25、nues to flow downstream or whether it is released into the atmosphere.For example，human engineering，like extensive dam construction，will result in dramatic changes to how water and sediments travel down the river.Some carbon that fails to reach the sea may return to the atmosphere in some way，which
26、causes more warming.Earths climate is closely related to the carbon cycle.We all know about the essential role of plants in consuming carbon dioxide，but do we know enough about rivers? Changing the chemistry and the course of rivers may have significant impacts on how they transport carbon.Remember：
27、wherever we live，we all live downstream.9Where is the carbon in rivers originally from?AThe atmosphere. BThe rocks.CThe acid rain. DThe upstream areas.10Why is human engineering mentioned in Paragraph 3?ATo show how important to life carbon is.BTo explain how necessary it is to build dams.CTo show h
28、ow a natural process is interrupted.DTo explain how humans fight global warming.11What does the author want to convey in the last paragraph?AWed better move upstream to live.BWe should protect plants along rivers.CWed better seek more help from plants.DWe should be cautious about river management.12
29、What is the best title for the text?AWhat Humans Do with RiversBHow Rivers Transporting Carbon CountsCWhat the Carbon Cycle Means to UsDHow Living Downstream Affects the Earth【语篇解读】本文指出，河流运输的碳对整个生态系统至关重要。人类不应该擅自改变水流的方向，因为这种行为会对整个生态系统产生巨大的影响。9解析：推理判断题。根据第二段第二句“Carbon starts its journey downstream whe
30、n natural acid rain，which contains carbon dioxide from the atmosphere，melts minerals in rocks.”可知，河里的碳最开始来自大气中。故选A。答案：A10解析：推理判断题。根据第三段的第一句“As carbon travels down a river，different processes may impact whether it continues to flow downstream or whether it is released into the atmosphere.”可知，第三段提到人类工
