给外国人解释旅游景点作文【一】
Dear Live Oak classmates,
How are you all? How time flies! It has been 8 months since I came back to China. Every time I look up at the photograph of our grade that was taken by Brittany’s mother and bears the signature of every one of you (this picture is now hanging up on the wall above our dining table, I cannot help thinking of you and the happy time we spent together. I do miss you often.
I am doing fine here in China and I like my present school life as much as I liked Live Oak. My classmates and teachers are very good to me, too. I have already caught up with my classmates in all the school lessons. Thanks to the Live Oak school education, I am now far ahead of my classmates in English, and I’m still doing a lot of English reading to keep up my English.
In the beginning of this semester, I was chosen to attend the School Robotics Team to practice for the robotics competition on behalf of my school. It’s a really big privilege, and I like it very much, because in my school there are one thousand and four hundred students and there are only four chosen. In the robotics practice, I learn to cooperate with my teammates and I need the big financial support from the school, because one single robot costs 50 thousand yuan. So it’s not a project that one person could do. We need to have team spirit as what we did in our Live Oak football game. On August 8, our school attended the national robot competition held in Xining, Qinghai, witch is neighboring Tibet. After two days’ competition, our team got a silver medal. During one of the days when we had no game, we went to the famous Qinghai Lake. It was so beautiful. It looked like an ocean because it was so large. Its water had many colors, blue, green, and purple, due to the ultraviolet rays.
I don’t go to church on Sundays in China, but I read the Bible with my mom every night. If we have time, we sing hymns too. God listens to my prayers. We have just bought a car. When our car was just two days old, my dad had parked the car just one centimeter away from the car next to ours. We were so worried that our new car would be scratched if the other car moved. In the evening, I prayed to God asking God to save our car. The next morning, we found our car in the parking lot safe and sound. And we were so thankful to God.
Although I have so much fun in China, I still miss the time I had in the U.S. Mrs. Moffat, thank you for letting me study in Live Oak, so that I have such a wonderful experience in my life. Mrs. Moore, I can still remember the big hug that you gave me the first time I visited Live Oak. How is Andrew doing? Has he passed all his surgeries? Some days ago, I have visited “Andrew’s Update” but I haven’t seen any updates. I hope that he is feeling better. Mrs. Brummeler, thank you for your patient help with my English in the first month when the new school life was tough for me and I could only understand a little bit of what was going on in class. Knox, thank you for being my first friend to offer help to me in class and letting me copy everything from your notes, including some small errors sometimes J. Hudson, how are you doing in your sports? I believe you are still the leader of the Live Oak Falcons. Joel, I miss the time that we were sharing grapes together at lunch time and we called that “Jump Grapes”. Andrew, hope you are still going to be the King at this year’s Christmas Nativity. And if you do, I hope you will have a good royal robe that you like. Ethan and Jordan, I will never forget that fabulous birthday party we boys had in the forest. Ethan, I thank you for the beautiful football that your cousin gave me. I have displayed it on the top of my bookshelf. Jordan, I am still keeping the two- dollar note that you gave me and it serves as my bookmark. Joshua, I thank you and your mom for taking me to school every day. I enjoyed the time when we were playing together. l wish we would be still playing ping-pong and pool together in that game room. Will, I remember that we had a fun time together when Mrs. Browning took us all together in her van to Jordan and Ethan’s birthday party. Luke, I miss the time when we were playing World War Ⅱ together at your house. I also remember the time when we were playing basketball together in the Baylor SLC and my mom said that you are a very nice and polite boy. Keegan, my mom had given her email address to your mom. If you ever come to China, please do come to Xiamen and visit me. Jerome, I really miss the time when we were playing tag in the playground. Caleb, I still remember that in recess time, you were always doing your Latin homework with Thomas as your “tutor” hanging on the “Monkey Bar” in the playground.
Dear girls, incase this letter would be too long, I’m not going to write to each of you. But do remember, I miss you as much as I miss the guys.
Hope all of you are doing well in your fifth grade life. I wish all of you can come to China someday in the near future. I look forward to being your host and showing you around my beautiful city.
I’d love to hear from you about anything fun in your life and our Live Oak Classical School.
Sincerely,
Joseph

一、（2013浙江湖州卷）阅读下文，回答问题。
感知地球的“千里眼”
近日，第三十五届国际环境遥感大会在北京召开，来自全球56个国家和地区的1000余位遥感专家参加了会议，这也是该会议发起50年来首次在中国举办，这说明我国遥感技术的应用发展得到了国际同行的广泛认可。
遥感技术兴起于上世纪60年代，是指从远距离感知目标反射、辐射或散射的可见光、红外、微波电磁波，从而对目标进行探测和识别的科学技术。人类目力有限，遥感技术的出现，让人类仿佛拥有了另一双可以无限感知地球的“千里眼”。
今年4月22日，国务院总理主持召开了部署芦山地震抗震救灾工作会议，在身后挂着一幅芦山县震后航空影像图。这幅影像图对抗震决策起到至关重要的作用。它是由中国科学院遥感与数字地球研究所（以下简称遥感地球所）提供的。遥感作业时间是4月20日11点，距离地震发生刚刚过去3个小时。那么科研人员怎么利用遥感技术评估判断地震灾情呢？
遥感地球所航空遥感中心主任李震说：“遥感航拍得到的高分辨率影像，能请楚地辨识建筑物、道路、河流、车辆等地面信息。科研人员运用专业知识，与震前的遥感观测数据比对，就能够判断建筑物和道路的受损情况，道路上堆积的滑坡物大小、滑坡的土方量等等，发现潜在的山体垮塌、堰塞湖等次生灾害，并确定财产损失的基本情况，确定救援所需投入的人力、物力等。”总之，利用遥感技术监测和评估灾情，具有定位准，速度快的特点，可以第一时间获取灾情数据，服务抗震救灾。
今年1月，我国中东部地区发生了数次极端强雾霾事件，主流观点认为，污染物排放量大，静稳天气、扩散条件不利，区域污染和本地污染贡献叠加等是导致强雾霾事件的主要原因。遥感地球所陈良富研究员基于遥感卫星观测数据的统计与分析提出，除了人为排放引起的本地污染浓度上升这一内在原因外，水汽、浮尘是造成雾霾来袭、能见度急剧下降的重要外部原因。
目前，对雾霾主要靠地面监测，但地面监测站只能监测地上几米高范围内的PM2.5数值。而灰霾随高度变化，分布不一样。利用激光遥感手段能获得霾的垂直分布情况，反映整个区域霾的二维甚至三维情况。如果不科学地认识极端强雾霾的发生机理，就容易判断错误，认为都是由排放的污染物引起的，在治理上进入误区。要得出科学判断，仅凭地面一种观测手段是不够的，还需要卫星遥感观测手段来补充，更全面客观地掌握大气污染状况。
另外，遥感技术对自然遗产和文化遗产的发现和保护的作用也不容小觑。应用遥感技术，美国考古学家发现了沉没海底数千年的古埃及名城亚历山大;希腊考古学家用红外像片在科林斯湾发现了公元前373年毁于地震的古城“Hekike”;遥感地球所郭华东课题组利用雷达遥感技术发现了阿拉善高原干沙覆盖下的古河湖串联系统和明、隋古长城……遥感技术也十分适用于文化遗产保护，它的优势在于能获得物体的三维图像。若能及早对文化遗产进行三维扫描，将来就可按照计算机模型对其进行复原。更重要的是，科学家还能依据这些数据分析破坏发生的原因，如温度、风力、湿度等，从而指导文物部门进行更加精细的修复。
总之，近些年，我国遥感技术发展迅速，在地震监测和评估，雾霾状况观测，自然遗产和文化遗产的发现和保护等方面广泛应用。
阅读下面句子，联系上下文，探究括号中的问题。
1.人类目力有限，遥感技术的出现，让人类仿佛拥有了另一双可以无限感知地球的“千里眼”。（为什么说遥感技术是“千里眼”？）
2.这幅影像图对抗震决策起到至关重要的作用。（黑体词为什么不能删去？）
