∵一张对边互相平行的纸条折成如图，EF 是折痕，∴∠C′EF=∠CEF=32°， ∴∠AEC=180°-2×32°=116°，所以②错误； ∵AC′∥BD′，∴∠BGE+∠AEG=180°， ∴∠BGE=180°-116°=64°，所以③正确； ∵GC ∥FD ，∴∠BFD=∠BGC=180°-∠BGE=180°-64°=116°，所以④正确． 故答案为：①③④．根据平行线的性质由AC′∥BD′可得到∠C′EF=∠EFB=32°；根据折叠的性质得到∠C′EF=∠CEF=32°，再利用邻补角的定义得到∠AEC=116°；由于AC′∥BD′，根据平行线的性质得∠BGE+∠AEG=180°，则∠BGE=180°-116°=64°；由GC ∥FD ，根据平行线的性质和对顶角相等得∠BFD=∠BGC=180°-∠BGE=116°．依此即可求解． 本题考查了平行线性质：两直线平行，同位角相等；两直线平行，同旁内角互补；两直线平行，内错角相等．19.【答案】解：原式=（3-12+2-32）×√7=3√7．【解析】根据合并同类二次根式的法则计算可得．本题主要考查二次根式的加减法，二次根式相加减，先把各个二次根式化成最简二次根式，再把被开方数相同的二次根式进行合并，合并方法为系数相加减，根式不变．20.【答案】解：原式=12×4×32×√6×12÷2=3√36=18．【解析】 ↵本题主要二次根式的乘除法，解题的关键是熟练掌握二次根式的乘除运算法则．直接根据二次根式的乘除法计算即可求出答案．21.【答案】解：原式=-27÷2+72-1 =-272+72-1 =-10-1=-11．【解析】先计算分数指数幂、绝对值和零指数幂，再进一步计算可得．本题主要考查实数的运算，解题的关键是熟练掌握分数指数幂、绝对值和零指数幂．22.【答案】解：根据题意知2x -3=0，y 3+1=0∴x =32，y =-1，∴4x -3y =9，∴4x -3y 的平方根为±3． 【解析】 此题主要考查了立方根、平方根定义和非负数的性质，其中求一个数的立方根，应先找出所要求的这个数是哪一个数的立方．注意：（1）一个数的立方根与原数的性质符号相同；（2）一个正数有两个平方根，它们互为相反数；0的平方根是0；负数没有平方根．首先根据绝对值和被开方数的非负性可以求x 、y 的值，再根据平方根的定义即可求解．23.【答案】解：原式=246×223÷216 =276．【解析】先把开方运算表示成分数指数幂的形式，再根据同底数乘法、除法法则计算即可．本题考查了分数指数幂．解题的关键是知道开方和分数指数幂之间的关系．24.【答案】PN；PM；PN；0【解析】解：如图所示：线段PN的长表示点P到直线BO的距离；线段PM的长表示点M到直线AO 的距离；线段ON的长表示点O到直线PN的距离；点P到直线OA的距离为0，故答案为：PN，PM，PN，0．先根据题意画出图形，再根据点到直线的距离的定义得出即可．本题考查了点到直线的距离，能熟记点到直线的距离的定义是解此题的关键．25.【答案】两直线平行，同旁内角互补；平行的传递性；两直线平行，内错角相等；128°；52；等量代换【解析】解：过点C作CG∥AB∴∠1+∠ABC=180°（两直线平行，同旁内角互补）∵AB∥DE（已知）∴CG∥DE（平行的传递性）∴∠CDF=∠2 （两直线平行，内错角相等）∵∠ABC=128°（已知）∴∠1=180°-128°=52°∵CD⊥DF（已知）∴∠DCB=90°，∴∠2=90°-∠1=38°∴∠CDF=38°（等量代换）故答案为：两直线平行，同旁内角互补；平行的传递性；两直线平行，内错角相等；128°（或∠ABC），52；等量代换．根据平行线的判定和性质解答即可．本题考查了平行线的判定和性质、熟练掌握平行线的判定和性质是解答本题的关键．26.【答案】证明：∵∠1=∠2，∠1=∠DGH（对顶角相等），∴∠2=∠DGH（等量代换），∴DB∥EC（同位角相等，两直线平行），∴∠C=∠ABG（两直线平行，同位角相等），∵AC∥DF，∴∠D=∠ABG（两直线平行，内错角相等），∴∠C=∠D．【解析】本题考查了平行线的性质和判定的应用，注意：①两直线平行，同位角相等，②两直线平行，内错角相等，③两直线平行，同旁内角互补，反之亦然，题目比较好，难度适中．根据对顶角相等和已知求出∠2=∠DGH，推出DB∥EC，根据平行线的性质得出∠C=∠ABG，∠D=∠ABG，即可推出答案．27.【答案】135°【解析】（1）①∵∠DCE=45°，∠ACD=90°∴∠ACE=45°∵∠BCE=90°∴∠ACB=90°+45°=135°故答案为：135°；②∵∠ACB=140°，∠ECB=90°∴∠ACE=140°-90°=50°∴∠DCE=90°-∠ACE=90°-50°=40°；（2）猜想：∠ACB+∠DCE=180°理由如下：∵∠ACE=90°-∠DCE又∵∠ACB=∠ACE+90°∴∠ACB=90°-∠DCE+90°=180°-∠DCE即∠ACB+∠DCE=180°；（3）30°、45°、120°、135°、165°．理由：当CB∥AD时，∠ACE=30°；当EB∥AC时，∠ACE=45°；当CE∥AD时，∠ACE=120°；当EB∥CD时，∠ACE=135°；当BE∥AD时，∠ACE=165°．（1）①根据∠DCE和∠ACD的度数，求得∠ACE的度数，再根据∠BCE求得∠ACB的度数；②根据∠BCE和∠ACB的度数，求得∠ACE的度数，再根据∠ACD求得∠DCE的度数；（2）根据∠ACE=90°-∠DCE以及∠ACB=∠ACE+90°，进行计算即可得出结论；（3）分五种情况进行讨论：当CB∥AD时，当EB∥AC时，当CE∥AD时，当EB∥CD时，当BE∥AD时，分别求得∠ACE角度．本题主要考查了平行线的性质，以及直角三角形的性质，解题时注意分类讨论思想的运用，分类时注意不能重复，也不能遗漏．。

Stanley Martin Lieber was born in 1922. When he was just 17, he got a job at a company that made comic books. As a writer, he started using the name—Stan Lee Ⅱ (which sounded like his first name, Stanley). He wrote his first Captain America story in 1941. It was very popular. Before he was 19, he was responsible for all writing for the company, which became Marvel Comics (漫威漫画公司) in the1960s. At the time, most superheroes were almost perfect. They were strong and smart and always knew the right thing to do. However, after working with some artists, Mr. Lee had some new ideas. He made it okay for comic book heroes to have weaknesses. The Incredible Hulk was a really nice guy until he got angry. Spider-Man was never sure he was doing the right thing, but he always seemed to have something funny to say to the bad guys. In 1980, Mr. Lee moved to California. He wanted to try and get his superheroes onto TV and into the movies. Marvel movies have now earned over $24 billion. Mr. Lee has played a small role in most of these movies, usually showing up (出现)on screen for just a few seconds. Mr. Lee is no longer with us, but the heroes he created live on.55．Who created many comic book heroes?56．Did he get a Job at a company that made comic books in 1939?57．What were the new ideas about after Mr. Lee working with some artists?58．How much did Marvel movies earn?59．What do you think of Mr. Lee?十、话题作文60．Write at least 50 words on the topic ‘________ makes me happy’ （以“________让我开心”为题，写一篇不少于50个单词的短文，要求内容适切，意思连贯，标点符号不占格。
