凤归云·恋帝里柳永恋帝里，金谷园林，平康巷陌，触处繁华，连日疏狂，未尝轻负，寸心双眼。

况佳人、尽天外行云，掌上飞燕。

向玳筵、一一皆妙选。

长是因酒沈迷，被花萦绊。

更可惜、淑景亭台，暑天枕簟。

霜月夜凉，雪霰朝飞，一岁风光，尽堪随分，俊游清宴。

导数中的朗博同构、双元同构、指对同构与二次同构问题目录方法技巧总结一、常见的同构函数图像1、同构式：是指除了变量不同，其余地方均相同的表达式2、同构式的应用：（1）在方程中的应用：如果方程和呈现同构特征，则可视为方程的两个根（2）在不等式中的应用：如果不等式的两侧呈现同构特征，则可将相同的结构构造为一个函数，进而和函数的单调性找到联系．可比较大小或解不等式．<同构小套路>①指对各一边，参数是关键；②常用“母函数”：，；寻找“亲戚函数”是关键；③信手拈来凑同构，凑常数、、参数；④复合函数（亲戚函数）比大小，利用单调性求参数范围． （3）在解析几何中的应用：如果满足的方程为同构式，则为方程所表示曲线上的两点．特别的，若满足的方程是直线方程，则该方程即为直线的方程（4）在数列中的应用：可将递推公式变形为“依序同构”的特征，即关于与的同构式，从而将同构式设为辅助数列便于求解3、常见的指数放缩：4、常见的对数放缩：5、常见三角函数的放缩：6、学习指对数的运算性质时，曾经提到过两个这样的恒等式： （1） 且时，有（2） 当 且时，有再结合指数运算和对数运算的法则，可以得到下述结论（其中） （3）（4） ()0f a =()0f b =,a b ()0f x =()x f x x e =×()xf x e x =±x ()()1122,,,A x y B x y ,A B AB (),n a n ()1,1n a n --)1();0(1=³=+³x ex e x x e x x )(ln );1(1ln 11e x exx x x x x =£=-££-x x x x tan sin ,2,0<<÷øöçèæÎp 0a >噍1,0a x ¹>log a x a x =0a >1a ¹log xa a x =0 x >()ln ee ;ln ln e xx x x x x x x +=+=ln :ln lnx x x xe e e x x x x-=-=（5）（6） 再结合常用的切线不等式lnx x -1， 等，可以得到更多的结论，这里仅以第（3）条为例进行引申：（7）；（8）；7、同构式问题中通常构造亲戚函数与，常见模型有： ①； ②； ③8、乘法同构、加法同构（1）乘法同构，即乘同构，如； （2）加法同构，即加同构，如， （3）两种构法的区别：①乘法同构，对变形要求低，找亲戚函数与易实现，但构造的函数与均不是单调函数；②加法同构，要求不等式两边互为反函数，构造后的函数为单调函数，可直接由函数不等式求参数范围；()22ln 2e e ;2ln ln e xx x x xx x x +=+=2ln 2ln 22,x xx x x x e e e e x x--==£ln ,e 1,e e exx x x x x £³+³ln ee ln 1xx x x x x +=³++()ln ln e e 1x x x x x x +=£-ln e e e(ln )x x xx x x +=³+()1ln ln x xx xe x x xe xe e-+=£=x xe ln x x 1ln ln ln ln log ln ln ln ln ln ln xx ax a x e a xa x e x a e x x x e x a x a e a>Þ>Þ×>=×Þ>Þ>ln ln 1ln ln ln ln x x x x x xee x x e x x x e x e x x el l l l l l l l l l >Þ>Þ×>Þ×>×Þ>Þ>()()()()ln 1ln 11ln 1ln 1x ax e ax x x e x ax x ++>+++=++Þ>+x ln ln ln ln ln ln ln x a x a x a e x x a e x e ×>Û×>×x log log log log a x x x a a a a x a x x x a x >Û+>+=+x xe ln x x x xe ln x x题型一：同构法的理解【典例1-1】对下列不等式或方程进行同构变形，并写出相应的同构函数．(1)； (2)；(3)； (4)；(5)；(6)； (7)； (8)．【典例1-2】关于的不等式有解，则实数的取值范围是 .【变式1-1】（2024·内蒙古·三模）已知函数.(1)讨论的单调性；(2)若恒成立，求的取值范围.2log 20kx x k -׳21e0xl l-³2ln e 0mx x x m -³()æö+³+ç÷èø1e 12ln ax a x x x ()()ln 1212e xa x x ax -+-³+ln e (1)x a x a x x x -++³>e 2ln 0x x x ---=2e ln 0x x x +=x e 2ln 2ln 2ax a x -£a ()22ln f x x ax x =-+()f x ()0,e axa f x >£a题型二：利用同构比较大小【典例2-1】已知，且，，，则（ ） A ． B ． C ．D ．【典例2-2】已知．且，，，则（ ）A ．B ．C ．D ．【变式2-1】已知a ，b ，，且，，，则a ，b ，c 的大小关系是（ ） A ．B ．C ．D ．【变式2-2】已知，，，则，，的大小顺序是（ ） A ． B ． C ．D ．题型三：方程同构【典例3-1】（江苏省常州市前黄高级中学2023-2024学年高三期初数学试题）已知实数满足，，则 ．【典例3-2】（江苏省泰州市泰兴中学2023-2024学年高三期中数学试题）已知实数a ，b 满足，则ab ＝ ．【变式3-1】设x ，y 为实数，且满足，则（ ）A ．2B ．5C ．10D ．2018【变式3-2】同构式通俗的讲是结构相同的表达式，如：，，称与为同构式．已知实数满足，，则 ．【变式3-3】（2024·高三·辽宁大连·期中）在数学中，我们把仅有变量不同，而结构､形式相同的两个式子称为同构式，相应的方程称为同构方程，相应的不等式称为同构不等式．若关于的方程和关于b 的方程可化为同构方程，则的值为（ ）A ．B ．eC ．D ．11,,,e a b c æöÎ+¥ç÷èøln55ln a a =-ln33ln b b =-ln 22ln c c =-b<c<a c b a <<a c b <<a b c <<,,(1,)a b c Î+¥2ln 22ln 12a a --=212ln 1eb b --=2ln π2ln 1πc c --=b a c >>b c a >>a b c >>c a b >>(0,1)c Î5ln ln 5a a -=-4ln ln 4b b -=-3ln ln 3c c -=-b<c<a a c b <<a b c <<c b a <<0.5ln 2a =()0.4ln5ln 2b =-()8ln 3ln 29c =-a b c a b c <<b a c <<c b a <<a c b <<,a b 2024a a e -=3ln 2021ln b b e -+=ab =20210a e a --=2ln ln 20190,b e b ---=()()3(1)2018153(1)201815x x y y -+-=-ìï-+-=íïîx y +=()e x f x x =+()ln ln ln e ln xf x x x x =+=+e x x +ln x x +12,x x 11e 6xx +=23522x =123x x +=a 24e e a a -=()31(ln 2),b b a b l -+-=Îe R ab 8e ln 6题型四：零点同构【典例4-1】（2024·高三·天津西青·期末）已知函数和．(1)若曲线数与在处切线的斜率相等，求的值； (2)若函数与有相同的最小值． ①求的值；②证明：存在直线，其与两条曲线与共有三个不同的交点，并且从左到右三个交点的横坐标成等差数列．【典例4-2】（2024·江西南昌·模拟预测）已知函数和有相同的最小值．(1)求；(2)是否存在直线，其与两条曲线和共有三个不同的交点且从左到右的三个交点的横坐标成等差数列？说明理由．【变式4-1】（2024·上海嘉定·一模）已知． (1)求函数的单调区间和极值； (2)请严格证明曲线有唯一交点；(3)对于常数，若直线和曲线共有三个不同交点，其中，求证：成等比数列．()e x f x ax =-()ln g x ax x =-()y f x =()y g x =1x =a ()f x ()g x a y b =()y f x =()y g x =()e x f x ax =-()ln g x ax x =-a y b =()y f x =()y g x =ln (),()e x x xf xg x x==()()y f x y g x ==キ()()y f x y g x ==キ10,e a æöÎç÷èøy a =()()y f x y g x ==キ()()()123,,,x a x a x a キキ123x x x <<123x x x キキ【变式4-2】已知函数和有相同的最大值.

It is a sweet job for a sweet tooth. However, the person needs to be good at maths. Chocolate has a melting (融化) point close to our body temperature. For that reason, chocolate melts easily in hot weather. You might think the advertisement from Cambridge University is funny, but if there is really a “doctor of chocolate”, he or she will help people a lot._________One logo (商标) isn’t too expensive to print because it doesn’t need much ink, but printing a large number of logos could cost a lot. In order to save money and energy, an American design company made small changes to some famous brands, such as Nike, McDonald’s and Starbucks, to cut the cost. The design company remained the main body of these logos, but left an empty space inside. The logos look almost the same, but in this way, the famous brands could save 39 percent of the ink during the printing. Let’s hope other companies will take this advice. The way will save them money and use less energy, too.Funny menu for childrenDining out with children can be an unpleasant experience for most parents, because kids are always runninground the whole restaurant, saying “I don’t know what I want” or “I’m not hungry.” But now, a Maryland restaurant has created the “Kid Friendlies” menu. It translates children’s words into meals to help parents order for their kids. A father said, “As a dad, I think this is on the money.” Here is the menu.Kid Friendlies“I don’t know.” - - - Triple Layer PB&J“I don’t care.” - - - Grilled Peanut Butter & BananaSandwich“I am not hungry.” - - - Basket of Chicken Tenders“I don’t want that.” - - - Kids Fries“What?” - - - Cheese Quesadilla31.

Less ink less waste.C①Imagine this: when you sit down and begin to eat a tasty tomato, suddenly it starts to cry! This thing will never really happen, but a new study shows that plants can make sounds when they are stressed.②Researchers from Tel Aviv University in Israel did the study. They used ultrasonic microphones (超声波麦克风) to record the sounds of tomato plants in boxes.③Three groups of plants were listened to: One group wasn’t watered for five days, another group had the stems (茎) cut off, and the third group was untouched. It turned out that the first two groups made sounds 30 to 50 times per hour, while the untouched group only made the sound once per hour. “When tomatoes are not stressed at all, they are very quiet,” Hadany from the team told CNN.④The researchers didn’t know how the sounds were made, but they believed the noise came from the breaking of air bubbles (泡) in the plants. This meant the noise produced by the plants was not on purpose.⑤Animals and insects may benefit (受益) from the sound. For example, the sound can tell a butterfly that the plant is under stress and not a proper place to lay eggs on. An animal that wants to eat a plant could also use the sounds to decide what to do, according to Science Focus.⑥After the experiment, the researchers listened to other plants such as rice, corn and grapes, and found they also made more sounds when stressed. Researchers said the study can help farmers in the future, as they can better take care of farm by “hearing” how plants feel.36. According to the experiment, we know that _______.A. the plants produced the noise on purposeB. the plants which had the stems cut off were very quietC. air bubbles in the plants broke and made the noiseD. the untouched group made more sounds than the other two groups37. How can animals and insects benefit from the sound of plants?A. To communicate by themselves.B. To break the air bubbles.C. To listen to other plants.D. To make right decisions.38. The study may help farmers to _______ in the future.A. improve the growth of plantsB. protect the environmentC. tell the weatherD. decide what to plant39. Which of the following is the structure of the passage?A. ①|②③④|⑤⑥B. ①②|③④⑤|⑥C. ①②|③④|⑤⑥D. ①②③|④⑤|⑥40. What’s the main idea of the passage?A. Plants that make sounds are tasty.B. Plants can show feelings by sounds.C. Researchers listen to plants.D. Animals benefit from the sounds.DHow would you like to build a time machine? Paper, sticks, glue and string are all you need. Put them together to build a kite. A kite connects you to the past.No one knows who flew the first kite. It was probably someone in China or perhaps Indonesia. Indonesian fishermen hung fishhooks on kites and sent them out to sea to catch fish. Starting 2,000 years ago, Chinese farmers flew kites to welcome the New Year and bring good luck to Earth.In China, people also used kites during the war. One Chinese story tells how people put noise makers on kites and flew them at night over the enemy camp. The enemies were afraid of the noise and ran away.About 1,300 years ago, Chinese travelers took kites to Japan. Soon kites filled the skies there. Kites reached Thailand about 700 years ago. During floods, Thai farmers flew kites over their fields. They hoped the kites would drive away the clouds and stop the rain. Over time, kites flew their way out of Asia. Today more and more people are crazy about flying kites. They are a passion all over the world. Kite fans meet at festivals in many parts of the world and have great fun together.Over the years kites have also helped people understand the natural world. For example, in 1906, cameras hanging from kites took pictures of San Francisco, California after an earthquake. The photos helped people plan what to do. Kites also helped inventors find out how to make airplanes. The Wright brothers studied how kites flew, which helped them make the first successful airplane.Since the ancient Chinese first set their kites into the air, people have loved flying kites. Kites give us ways to celebrate, relax and explore. So go fly a kite! Enjoy the feeling that kite flyers have felt for centuries.41. In which countries were kites used to make good wishes?A.

By listing numbers.C. By comparing facts.D. By giving examples.,.45. What’s the purpose of this passage?A. To show people how to fly kites.B. To explain how kites are used in science.C. To introduce the roles of kites in history.D. To discuss the difference among kites worldwide.第二部分非选择题（共55分）任务型阅读阅读下列短文，根据短文中的信息完成文后的表格。

专题06 从句（定语从句、状语从句、名词性从句）（新模拟和新高考）I.语法填空1. 【江苏省苏锡常镇四市2021届高三教学情况调查（一）】Like any natural force, gravity pull can work with us or not. The gravity pull of our habits may currently be keeping us from going 64．we want to go.【答案】where (wherever)【解析】考查状语从句。

句意：现在，习惯的引力可能正在阻止我们去想去的地方。

分析句子可知，动词going为不及物动词，后接地点状语从句，表示“（无论）……地方”。

故填where (wherever)。

2.【2021届江苏省南京市高三学情调研】"He then handed Todd a large bag, inside 43．were clean shirts and shorts, plus a brand-new pair of New Balance sneakers. Todd was blown away."I was very happy." he toldWATN-TV."Shocked, completely."【答案】which【解析】考查定语从句关系词。

句意：然后他递给托德一个大袋子，里面有干净的衬衫和短裤，还有一双崭新的纽巴伦运动鞋。

分析句子结构，“inside ____ were clean shirts and shorts…”是定语从句，先行词a large bag，指物，因此用“介词inside+which”引导定语从句。

故填which。
