Yasmin Eisenhauer, a teacher at Lowell School, told her class last fall that they were going to make the trees on their school grounds talk．"What? How are we going to do this?

" Then "Charlotte" tells the listener all about her leaves, and how big she is． She ends by saying: "I hope you come back to visit me because of course I can't come to you．"The project took a whole year to complete． The kids met about once a week to work on it． Now visitors can visit the Lowell school grounds during off﹣school hours and take the tree tour with their cellphones by calling a phone number that is on a sign next to 22 trees．（1）How did Lusya feel when she heard what he teacher said？________A Disappointed．B Surprised．C Worried．D Excited．．（2）According to the text， Charlotte is________．A the tree Brooke pickedB a visitor to Lowell SchoolC the organizer of the projectD Brooke's classmate and friend．（3）To carry out the project， the students have to________．A become very creativeB improve their math skillsC know a lot about new technologyD be quite familiar with their trees．（4）We can infer from the passage that________．A Lowell School has 22 trees in totalB Yasmin Eisenhauer is a crazy teacherC the project will last for a couple of yearsD the students were interested in the project．（5）The passage is mainly about________．A the talking treesB the clever studentsC the latest technologyD an experienced teacher．19. Studying music in high school is good for young people． Unfortunately, students do not think of music studies as a useful subject in high schools． They always learn other subjects or sleep in music classes． However, educators have seen the great difference which studying music has made in the minds and lives of their students．Some studies find that children who study music have better grades． According to Robert A Cutietta and Harvey Mercadoocasio, authors of "Raising Musical Kids: A Guide for Parents", "Students who study music in high school, as a group, have higher scores than those not in bands．"Studying music may not immediately lead to higher grades． It does, however, make students gain skills that can lead to success in tests．Through listening to music, one can enjoy the joy which music may bring into his life． Performing as a musician increases this joy, while developing self﹣confidence． According to Cutietta and Mercadocasio, "Being involved in music in a meaningful （and knowledgeable） way will add greatly to the quality of your child's life． It increases brain power along the way．"Studying music as a high school student allows teenagers to develop many healthy and productive habits that will carry over into their adult lives, giving them a push towards a successful life． In addition to these habits, studying music really changes the brain in some way, as well．"Kids who receive music training often make great progress in math studies．" According to Newsweek． It quotes psychologist Martin Gardiner: "they just ________ in math． This can't be explained by attention alone． There is something specific between music and math．"（1）As for high school students， the author holds that________．A they understand music studies in high schoolB they should learn other subjects instead of musicC they should take music studies seriouslyD they can choose to study music as they like．（2）Studying music in high school________．A immediately leads to high gradesB helps students improve in someskills C changes students' lives in high school D provides more joy than listening to music．（3）According to Para.4， listening to music can________．A bring one some joyB develop self﹣confidenceC improve parents' lifequality D increase adults' brain power．（4）Why is studying music good for young people's future？________A Because it lets young people get good grades．B Because it improves young people's life quality．C Because it makes young people more confident．D Because it makes young people develop good habits．．（5）What do the underlined words "shoot ahead" in the last paragraph mean？________A Practice a lot．B Show interest．C Move quickly．D Improve greatly．第一节：阅读表达（满分10分）阅读短文，并按照题目要求用英语回答问题．20. Eating is the best when it's a social occasion． Think of the meal a family enjoys in the evening when everyone's together after work or school， or the big get﹣togethers over food at Spring Festival． But now， in the age of the internet and social media， anyone with internet connection can enjoy a social eating event．Mukbang ﹣ a South Korean phrase meaning "eating broadcast" ﹣ is an unusual food craze that's popular across the country． This is a meal where only one person gets to eat while viewers watch live stream of hosts ________ large quantities of food． They leave commentson the dishes the host is enjoying， and the host responds to them live．So why have people taken to this unusual new food trend？ Jeff Yang， an Asian﹣American cultural critic， thinks it's down to "the loneliness of unmarried or uncoupled South Koreans"． He believes that eating on your own can be hard in the country like South Korea，where social eating is such a long tradition． However， Mukbang gives people the feeling that they are part of something larger， it seems．Millions of people have trouble with food． Either they eat too much of it， or toolittle． Some say that the popularity of Mukbang helps people with these disorders． Those who always eat too much and put on weight can watch Mukbang streams to satisfy their appetite． And those who don't eat enough can build their appetite by watching delicious food being eaten．Even though Mukbang is a South Korean phenomenon， it's also taken off in the US． But unlike South Koreans who sit down to enjoy noodles and kimchi（泡菜）， Americans enjoy their own native dishes． This means that viewers of US Mukbang streamers will see local eating hamburgers， fries and ice cream．（1）What does the underlined word "devouring" mean？（1 word）________（2）Why is Mukbang becoming popular in South Korea？（no more than 10 words）________（3）What is the article mainly about？（no more than 10 words）________（4）What is the specific trouble millions of people face in South Korea in the passage？（no more than 10 words）________（5）What do you think of Mukbang？ Put it in your own words．（no more than 20 words）________第二节：书面表达（满分20分）．21. 假如你是新华中学的李津，请根据下面提供的信息，给你的澳大利亚的笔友Jack写一封电子邮件，介绍你近期参加学校国画社（Chinese painting club）活动的情况，并谈谈收获和感受．1．活动：（听有关国画的讲座；参观展览；练习国画……）2．收获和感受（……）注意：（1）字数不少于100词；（2）邮件的开头和结尾已给出，不计入总词数；（3）适当增加细节，以使行文连贯．Dear Jack，How's everything going？I'm very excited to tell you that_____Best regards．Yours，Li Jin2018-2019学年天津市部分区联考高二（上）期末英语试卷答案1.

一、单项选择题：1.关于质点，下列说法中正确的是A. 体积小的物体都可看成质点B. 质量大的物体一定不能看成质点C. 地球不能被视为质点D. 在体操比赛中，裁判不可以把运动员看成质点【答案】D【解析】【详解】当物体的形状、大小对所研究的问题没有影响时，我们就可以把它看成质点，并不是体积小，如原子核很小，在研究原子核内部结构时，原子核不能看成质点。

故A错误；质量大的物体不一定不能看成质点，例如研究地球的公转时刻把地球看做质点，选项BC错误；在体操比赛中，裁判不可以把运动员看成质点，否则就没动作可言了，选项D正确；故选D.2.如图，粗实线是某同学晨练的轨迹图，用时32分11秒，跑步5公里，根据图中信息可知A. “5公里”指的是该同学的位移B. “5公里”指的是该同学的路程C. “32分11秒”指的是时刻D. 该同学的位移方向由终点指向起点【答案】B【解析】【详解】“5公里”指的是该同学的路程，不是位移，选项A错误，B正确；“32分11秒”指的是时间间隔，选项C错误；该同学的位移方向由起点指向终点，选项D错误；故选B.3.关于惯性下列说法正确的是A. 只有静止的物体有惯性B. 只有运动的物体有惯性C. 战斗机战斗前抛弃副油箱，是为了减小战斗机的惯性D. 火箭升空时，火箭的惯性随其速度的增大而增大【答案】C【解析】【详解】一切物体都有惯性，与物体的运动状态无关，选项AB错误；战斗机战斗前抛弃副油箱，是为了减小减小质量，从而减小战斗机的惯性，选项C正确；火箭升空时，因质量不变，则火箭的惯性不变，选项D错误；故选C.4.汽车的百公里加速时间指的是汽车从静止加速到100km/h所用的时间，是衡量汽车性能的一项重要指标。
