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? " thought Lusya Mae Engen, a student in Yasmin's class．But the kids soon learned what their teacher meant．"We're trying to get people to talk with the trees through technology, " said Lusya．First, the students picked their own trees． Then, each student had to learn all about his or her tree, like how tall it was, how the tree's leaves felt and looked, and during what season it flowered． To get all the information, they used the Internet and some math．Next, the students wrote what they had learned about their trees and they recorded their own voices talking as if they were their trees, telling people all about who they were． That was the technology part．"It was really cool to connect technology with nature, " said Azur Walla, another student in the class．The kids named their trees things like Dog 'N' Woods, Harlo Tree or Freddy． They also added their own creative voices to the project, and asked people looking at the trees to sing a song in their shade or give the trees a hug．"My name is Charlotte． I was given this name by my friend Brooke． She is really nice and tries to visit me every day． What is your name?

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.

【解析】【分析】（1）连接1AC ,交1AC 于点O ，连接DO ，能证出1//BC DO ，则能证出1BC ∥平面1ACD.（2）先把1AB ⊥平面1ACD 当做条件，得出11AB A D ⊥，得出1AA AB的值，过程要正面分析. 【小问1详解】连接1AC ,交1AC 于点O ，连接DO ， 因为O 是1AC 的中点，D 为AB 的中点， 所以DO 是1ABC 的中位线，即1//BC DO ,1BC ⊄平面1ACD ，DO ⊂平面1ACD ， 所以1BC ∥平面1ACD . 【小问2详解】1AA AB =时，1AB ⊥平面1ACD ，证明如下：因为1AA AB =，11tan A AB ∴∠，111tan AA DA B AD ∠= 1111A AB DA B ∴∠=∠，1112DA B AA D π∠+∠= ，1112A AB AA D π∴∠+∠=，即11AB A D
